With the development of science and technology, we also have a TV gradually replaced the original black and white color , and its radiation performance compared to the previous TV is also greatly reduced, especially the recent popularity of LED full color display to says it uses the most advanced high-end light-emitting materials and high-quality special IC chip , not only show good results , but the large viewing angle display more fluid , has occupied a leading position in the current display market .
Main components of LED full color display has a power switch ( responsible powered LED display full color display ), scanning control board ( responsible for data buffering ) , a display unit ( which is part of the display screen ) , metallic structural framework ( control LED constitute the framework of full color display ) , twisted pair cable ( data transmission ) , the main controller ( responsible for data buffering and combinations and generate various control signals ) , dedicated graphics cards and multimedia cards ( whose role is more on the computer display card similar functions ) , and other components , but with the constant development in recent years, LED full color display , the current full-color LED display on the market in terms of quality and price are good and bad, so if you want to buy LED full color display , the top priority attention to the following points:
1 , display brightness LED full color display
We know full color LED display screen is by the light emitting diode emits light to achieve imaging results, so once the brightness is not enough, it shows the poor quality of its diode , usually for LED brightness for indoor full color display to control the brightness of 800cd/m2 or more, while the outdoor requirements are higher, and usually 1500 cd/m2 or more.
2, LED full color display whether the balance
Zhengzhou Feng Shuo LED display Shun Hing Electronic Technology Co., Ltd. introduced , we know that if you want to show white display , it is needed by the red, green and blue colors to fit the proportion 1:4.6:0.16 able to show up , so If it does not display the precise control of the control system , then it is easy to appear yellowish , greenish , bluish and other white display.
3 , if there is not change the color of the pixel full color LED display
We know that the image is displayed full color LED display is a small point by a luminous color composition of these small points are not fixed, if the display image needs some small dots appear as white , these little white pixels will be displayed , If one of these images need to display the red dots , these dots and need to become red , so as to have a single pixel if some necrosis appears on the display with the received image effects , these will affect display pixels display screen or some constants normally black state, and the main cause of this phenomenon is due to the quality of its decisions die .
4 , whether full color LED display color transition
That runner color display pixels of two adjacent lot , resulting in uncoordinated display , and the main cause of this phenomenon is mainly due to the full -color LED display control system for poor reasons.
5, LED full color display surface is flat
Zhengzhou Feng Shuo LED display Shun Hing Electronic Technology Co., Ltd. pointed out at the time of purchase of full-color LED display if you find that the surface is very rough, and also appeared locally convex , etc. , then these will affect the full-color LED display display quality , resulting in distortion of the display screen , thus like this type of full color LED display , do not buy , generally speaking full-color LED display surface flatness to the lusm 1mm or less .
6, LED full color display color reproduction
Also refers to the color reproduction and consistent color display received appears to keep its color , or not called to restore order to ensure the authenticity of the effect of LED display

Next few years, all businesses strive to place the LED industry broke the news
At
this stage, with the gradual increase of micro-channel users , mobile
Internet portal also intensified the battle , LED lighting business in a
variety of business models also need to strengthen and consolidate . It is understood that some of the LED lamps brands have started to
start their new media marketing plan , and micro-channel marketing is
one of the more powerful one.
In the industry view , the food, cosmetics, FMCG able to attract such a large number of new fans to continue to focus on its various promotional information , LED lamps are one-time home of large slow- moving consumer goods, the growth of new consumer group is relatively slow . "We are on the micro-channel services are mainly old customers , offer some follow-up services after purchase for them ." He said.
The current micro-channel public number is also not the best way to open up new customers, the place is that it is more effective to maintain existing customers through micro-channel systems. "Old customers may re-decoration , but also to our latest event information learned introduction to a friend or forwarded to their own circle of friends, word of mouth into sales ." Insiders said very valued between known and potential customers the depth of the contact , finally being recognized, converted to business sales .
A person in charge of an LED lighting company declined to be named said that compared to two-way communication , consumers prefer to interact by means of credible third-party platform . "We're selling it as an aid to the store , in addition to face to face increases , the opportunity to communicate with consumers ." The source said.
LED lighting business or as a marketing tool permeability
In fact, although many companies have recognized the LED lamps "universal micro-channel " influence , but for now, various industries and enterprises , as well as micro-channel background itself , everyone in the development and use of micro-channel marketing platform is still in the exploratory stage .
An industry point of view , believes that the existing micro-channel feature also stop at only as a long-lasting penetration of marketing channels. Because of privacy protection micro letter , LED lighting business is not easy to "grab consumers ' to LED lighting company, for example , the existing micro-channel marketing is far smaller than the list according to residential property owners , businesses directly target the needs of consumers by telephone marketing more efficient and effective .
2014 , LED lighting manufacturers in the application of micro-channel platform for the occasion , more to think about is how to make products faster and more accurate is received consumers. At the same time , how to provide consumers with more convenient service . Micro-channel marketing in the coming years will become the land of all businesses strive , therefore, first mover advantage early profit !

Precautions purchase and installation methods of decoration LED lights
LED lights with after several years of rapid development , the market
presents a variety of LED lights, the uneven quality of good and bad .
Consumers in the purchase using their eyes to polish their quality
choose the right lights, remember not to take any cheap . The first flexible led strip network Xiaobian today summed up the following points of home improvement pro for reference, we want to help.
A color
From the color points , led lamp with a light color, white , warm white ( yellow light ) yellow and blue , and so on . In theory led many colors can be retrieved , so few mainstream color , because many factors affect the light color , so the color temperature of light with different batches generated there will be some deviation . For example, warm white 3000K and 4000K will be divided into color temperature , white color close to the sun as well as cool white, tiny chromatic aberration. Home decoration and daily use , mostly because basically warm white warm white reflects the warm environment , the bright white and blue fashion. Light colors can be selected according to their own preferences, home decoration style.
Second, the model
1 There are many types of lights with flat third-line market , per second, flat four-wire , led lights, and so kind . Because of led lights with energy saving, environmental protection, long life, clean and affordable. Etc. have occupied a major position of home improvement . Old-fashioned flat three-wire lights with low brightness and power consumption is not only large , has basically been eliminated. So choose when to use lights with led lights ( LED type of patch ) . Model LED lights are commonly used in 3528 and 5050 . ( 3528 refers lights inside the chip size is 3.2 W 2.8 mm long rectangle ) 5050 refers to a chip with a light band width is 5 mm . ( 5050 chips because of the large ratio of the chip 3528 of the lot, so 5050 is relatively higher than the luminance of about 70% brightness 3528 . )
2, led strip light based on the number of lamp beads can be divided into 60 Pearl 72 Pearl 68 Pearl 90 beads , common specifications , in daily to buy the corresponding specifications can be selected according to the size of the installation space , the use of purpose. If it is cooler home decor, desk decoration, do not ask for the case of brightness can choose 3528-60 beads , decoration 8-15 square meter room can use beads 3508-68 Gold Edition models, or use 5050-60 15 square meters or more rooms beads recommended to use the classic 5050 - upgrade to subsection ( 72 beads ) so that the brightness of the light to keep the room relatively modest coordination , the next picture shows the 3528 's led lights .
Three: Note .
Part of 1.led lights , there lamp beads - guides - wire - wrapped plastic - Resistors - Wire - accessories.
Note that when you choose to buy the regular brands , so quality can be well protected ( when the lights with optional width guides to choose 6 mm or more , less than 6 mm in width guide is not enough because the circuit board can cause lights generate a lot of heat , there is a serious security risk, so pay attention to when buying guide width light band. )
2 , when the lights cut to note that there are special scissors mouth , usually one meter lamp with a loop , the entire meters usually have a 1 cm gap is a special needs from the mouth of scissors cutting scissors mouth .
3, the led strip are accessories , accessories are generally cross-flow plug ( that transformer lights must be used ) line cards ( fixed lights with plastic clip ) tail plug ( protection lights with the tail of the plastic condom ) to buy lights with time to ask businesses , otherwise you missed parts nor oh.
Four: Installation
For the terms of the purchase , installation much simpler ,
A direct bar lights with nails to the lamp with clamp groove
2, back glue ( adhesive ) paste into the lamp compartment
All OK . This is generally good job electrician .

Graphite heat is reflected materials chemistry
Many
called cold light LED , LED light source is actually hot , because the
LED during operation a large amount of power transferred into heat. Poor heat will cause damage to the power supply , the light fades
faster, shorter life expectancy and other issues, the heat issue has
always been the top priority of LED , LED heat dissipation is a concrete
manifestation of materials chemistry .
LED light engine has occupied senior Crystal Light 2-5 % market share , graphite heat from the LED light engine power LED light source components, metal thermal column ( referred to as " thermal column " ) , high thermal conductivity graphite body composition. LED light engine as a separate light source device , the unit area is small , small , multi-unit combination of freedom of choice , conveniently mounted on the mounting holes reserved for carrying platform , made of lighting, design increases the degree of freedom ; Users more may need to use the freedom to assemble. Simple, independent LED light engine has been successfully developing and manufacturing a variety of LED application products : crystal lamps, candle lamps , bulb , MR16, module modular lights.
Graphite heat LED light engine has been fully applied to the light source to replace the crystal , LED light engine does not affect the independence to make it come off the light from the lamp above the other , to facilitate the ongoing maintenance of lamps and save maintenance costs, even if one or two of them light the engine broken in the case of UPS , and a few seconds to re- put a new light engine. Prices for customers are most concerned about , the lowest four yuan / W, price depends on the chip quality , " ten a few watts too.
Traditional aluminum heat sink material , good thermal conductivity, heat capacity but poor . , Thermal conductivity and heat dissipation are the two concepts.
Graphite material inherent physical and chemical properties make it superior thermal performance . Preparation of high demand but low efficiency and low cost , has become an obstacle to the development of graphite thermal material bottleneck . Plasticized material graphite thermal material developed simultaneously with superior thermal performance , high production efficiency and consistency , mass production , thus a higher price advantage. LED heat dissipation in the industry , with a light weight, small size , fast heat dissipation , the combination of freedom and other advantages .
Plasticized material graphite heat sink cooling speed, high efficiency ; direct exchange heat with temperature and indirectly improve the environment , independent heat exchange , thermal heat deposition polymerization and thus a reasonable transfer and exchange , so that the internal temperature of the heat source of heat deposited poly controlled within a safe range .
Works vividly graphite heat plasticized material metaphor for the human body fever , when the body temperature above normal body temperature , the pores will expand to the heat by sweating to export . Similarly, the plastic is when heat reaches a certain temperature they will draw moisture out of the space , to ensure the active ionic bond is opened, the heat dissipated .
Faced with the cottage industry of various plagiarism flooding , product homogeneity serious , for the cottage , the cottage is no future , only imitation of its appearance , but its unknown reason . "LED heat is reflected materials chemistry , materials chemistry only to have a full understanding , in order to make a good product.Industry will face a reshuffle
With the development and improvement of LED technology , materials for LED heat dissipation is also innovation, from aluminum to ceramics , to the new composite material ( plastic clad aluminum ) , heat dissipation materials market competition becoming increasingly fierce. Coexistence of various thermal materials have space, but ceramic , plastic coated aluminum and other market share will be compressed , because the ceramic molding difficult, and fragile, adding requires a lot of energy ; rather expensive metallic materials in LED lighting products prices continued to decline under market conditions , it is not so economical.
LED lighting popularization rate will accelerate in 2020 will replace all incandescent lamps. With the improvement in technology , the popularity of automated production , no technology , no core competitiveness , " screwdriver " plants will be eliminated in the new round of industry reshuffle .

Currently many places the semiconductor lighting energy industry as the focus of industrial development , intensify support , but also the existence of blind investment and low-level construction of the phenomenon , some local governments in spite of the economic benefits of road lighting blindly transformation, over- investment landscape lighting leading industry disorderly competition , product quality varies greatly, serious waste of resources , impact on consumer confidence , is not conducive to the healthy development of the industry . Disorderly market competition often leads companies to ignore technological progress and product quality improvement, less investment in research and development .

Where is the contradiction in the LED lighting industry?
In
early January, the country's new formulation of "embedded LED lighting
performance requirements" and other national standard release, the
standard is expected to be implemented in October this year, and for
2014 the LED lighting market for further specification. Currently,
because the price is not close to the people, energy and other obvious
reasons, LED lighting products have not been home consumer acceptance,
production standards are not clear but also to distributors,
manufacturers face many confused. The new standard specification for the role of markets in the end how much remains to be seen.
LED lamps are not high consumer acceptance
Will be explicitly requested "Embedded LED lighting performance requirements" national standards each year to engage lamps lighting manufacturers strictly in accordance with the development and production of human life and production in line with quality standards and technical regulations to provide for the current lighting industry norms and guidance.
Standard one, LED lighting lamp replacement tide on the argument heard. According to many years living in Beijing NVC agent Monica house industry trade Co. stores are actually pretty hairy ho introduced in addition to the advantages of LED energy-saving, life is also 2-3 times higher. In this regard, Zheng Zhang Shanghai enterprises an illumination (Beijing), general manager of the company's flagship store, also said LED recognized that although Zheng Zhang LED lamps in the initial purchase relatively expensive, but because of the use for a long time, so the average is actually to save money every day . Because of different light emission principles, LED also has a good perspective of, widely used in public spaces.
However, the performance is so superior LED lighting, consumer acceptance is not high. Two years ago, when Ms. Xu consumers used home decoration LED ceiling lamps, two years later, Ms. Xu insisted in exchange for energy-saving lamps. According to Ms Xu introduced, home LED lights use less than a year is not bright, sale and said it was normal. "Brightness getting lower and lower, the original seems to have not much to say saving the province."
Only use problems, time to market again to buy lamps, LED lamps changes in the price also let Ms. Xu feel very "do not fly." Had spent more than fifty yuan to buy lamps, and now the price is less than thirty yuan. The original ten million energy-saving lamps, it is now more than ten dollars. Compared the two, Ms. Xu decisive choice of energy-saving lamps.
Whether the use of LED lighting in the home energy saving, indeed debatable. For example a room using a 6 watt LED lamps replace 12-watt energy-saving lamps, electricity saved one light year is less than $ 10. However, with an LED light to replace the original energy-saving lamps, they spend tens of dollars.
General Manager Zhang Jing told reporters lighted and decorated the city, because from the market point of view, consumers rarely use LED lights, the price is still not enough close to the people. But because the shape of the color change LED lighting and more at home can be used as an auxiliary light source.
Dealers can "touch stones"
Zhao was a dealer lighted decoration of the city, six years ago to get involved in LED lamps. According to Zhao, the current consumers to buy LED lamps only 20%. For LED lamps, Zhao said dealers are also feeling the stones, "not to mention consumers brightness decay and price volatility issues very angry, and we are very worried."
Because of the promise the sale of products within one year warranty, Zhao encountered in the past few years many times because the situation requires bright enough to replace. "We can only say that LED are explained to consumers of new products, technology is not yet mature." Zhao recalls, manufacturers will be replaced when the purchase again, but whether the new product manufacturers will have problems, only to see the market feedback.
The market price of LED lamps for letting down frequently and more dealers are afraid to purchase. Currently out of the market as fast as the speed of the new companies have joined, although often hear business failures, the market is still no shortage of low-quality products. China Association of Lighting Chen Yansheng said, whether or media hype is to promote policies, LED lighting industry is currently participating companies are too much.
Many companies also want to do LED pushed the industry, resulting in an overheating situation, while consumer demand has only just begun. Oversupply, giving rise to a relative surplus of production capacity. Plus lamps produce mostly inter-related, and some accessories such as chip brand manufacturers can not even produce, and the quality of the introduction of chip and can not judge, so manufacturers seem to face greater confusion.
The industry voice
Manufacturers should consider the long-term interests
Chen Yansheng, director of China Association of Lighting
LED can develop different styles, different types of products, giving the company offers a lot of room, but no matter what type, should be responsible for the consumer. Because the LED current fierce competition in the industry, a lot of products for the price, once the price cuts, it is possible for manufacturers to drive down costs and improper selection or even cut corners. People bought after a bad product, the LED will produce a feeling of mistrust, but now they do have this situation. Therefore, manufacturers should consider the long-term interests, not to focus on price competition, lower product quality, harm the interests of consumers. The current situation will not last long, the future will certainly Ebb Tide, there will be some companies are eliminated.
All-out energy-saving lamps unrealistic
Shan Ho, general manager of Colliers International Lighting Hong Kong
Now LED and must do more and more, but all-out energy-saving lamps also not realistic, after all, not a country for LED established standards. Now manufacturers, distributors, stores, selling lamps came in a hurry, but anxious to no avail. From the sales point of view in recent years, awareness of consumers to buy LED lamps indeed enhance sales in 2014 will surely be doubled. With the enhancement of self-testing and manufacturers of production technology, product quality is also improved, but this process will take time.
LED lighting performance requirements and more
Zheng Zhang, Shanghai enterprises an illumination (Beijing), general manager of the company's flagship store LED
A good quality LED lighting is not good, long life is not long, light attenuation is worse, is determined by many factors. One chip, the chip is good or bad for the life of the lamp play a decisive role. Some small manufacturers use recycled scrap chips are used as raw materials, the quality is even worse. Second, the heat, the heat is not good, more than 40 degrees will reduce the life of the chip brightness decay occurs. Third, the power supply, turn on the lights when similar "trigger" if instability will affect the life of the lamp. However, when consumers buy more concerned with the product casing, anyone can do this part, but is the least important.
Observer reporter
The limited role of the new standard
Shan Ho, general manager of the Hong Kong International Lighting Colliers said Colliers International in Hong Kong although the establishment of the LED lamps lighting area, the introduction of the brand when to call for qualified materials, but only by ordinary lantern light even some norms to constrain LED lamps. "There is no specification specifically for LED lighting." Ho Shan said.
Because there is no established norms, LED lighting industry, eliminate ineffective. Such competition is bound to induce a price war, prices down frequently, some small businesses to cut costs, product quality can not be guaranteed, indirectly reducing consumer confidence LED lamps.
For the country's new "embedded LED lighting performance requirements," the Beijing News reporter understood by the parties, the standard is still only know the name, I do not know the specific content. According to the Secretary-General of China Association of Lighting Dou Linping introduced new standards published text must be printed by a specified printing after the National Standards Commission announcement. Although you do not see the content, but we can see that the new standards would be more stringent in the past on a range of safety standards for lighting, and then raise the standard of performance, to further regulate the industry. Dou Linping also said that because of different lighting environment requirements are not the same, so the new standard non-mandatory standards, its role is limited and not conclusive. The standards in the implementation and monitoring of the process will increase the cost of natural products, consumers are willing to spend this part of the costs, but also need to wait for the market investigation.

Quality first LED lighting prospect of hospitals
Since 2011 , Guangdong Province, began issuing energy saving policies , the implementation of favorable policies have led to the city roads , hospitals , schools, libraries and other public lighting places the city 's demand for energy-saving light source in the lighting installation , use LED seems become the first choice of various departments.
All of the light source from the market for now , LED is the most energy-efficient artificial light , replace incandescent , fluorescent, halogen and xenon lamps and other lighting with LED light source , the average energy savings of more than half. Precisely because , LED energy-saving effect is gradually being accepted by the market . Insiders told reporters that in 2014 China's LED both in circulation or engineering sales channels will be made great strides.
Meanwhile , the State Lighting R & D and Industry Alliance Geng Bo , Deputy Secretary-General also believes that if you press the demand for LED 's and their words carry echelon type sort , underground parking , shopping malls , supermarkets , hotels, restaurants belong to the first echelon , office factories belonging to the second echelon , hospitals, libraries followed.
As Geng Bo said, as the city's major public lighting market segments , the hospital has been an important area of LED lighting business concern.
Prospects
A few years ago , due to the very high price of LED lighting products and the quality is not stable , LED light source in the hospital range is not large . However, under favorable policies to stimulate the industry generally believe that with the steady decline in the price of LED lighting products and product quality , LED lighting products into the hospital imperative.
The second half of 2013 , the Regional People's Hospital of Shenzhen Nanshan , Yantian People's Hospital , several large hospitals have performed on hospital building and other energy-saving LED makeover . Guangzhou, Dongguan, Zhongshan and other cities in major hospitals have started companies bidding on LED energy saving.
"LED into the hospital during the hospital side is a positive attitude ." Shenzhen Optoelectronic Design Director billion capsules魏志国In an interview with Engineering "LED lighting channels," said in an interview , as opposed to ordinary home lighting and commercial lighting field hospital for LED lighting product acceptance is much higher.
Market acceptance is an important factor in promoting LED products into the hospital, but the hospital around the clock as needed lighting large electricity itself has all the advantages of energy saving and long life LED lighting products will directly affect the market 's perception of LED products . Wei Zhiguo that, although the purchase cost of the product than ordinary LED lighting traditional higher, but from a long-term perspective , LED lighting and more purchase value.
For example, some time ago , a hospital for the relevant parameters such as surgical lighting power consumption for the corresponding inter- comparison test , the results showed that the overall hospital with LED lights , energy saving effect is remarkable , hospital annual savings of electricity 265,900 degrees, combined with its lamp replacement costs and maintenance costs , the cost advantage is obvious.
Another aspect , more than the number of health care institutions . According to the National Health and Family Planning Commission issued the " 2012 China Health and Family Planning Development Statistics Bulletin " shows the end of 2012 , the national total of 950,297 health care institutions , including hospitals 23,170 , 912,620 primary health care institutions , professional public health agencies 12,083 , other agencies 2424 .
And in all medical institutions , the vast majority of organizations are using incandescent lamps and energy saving lamps can be replaced if the process is changed to LED lighting , the LED 's prospects will be very bright.
Quality first
Although LED applications in medical institutions vast , but currently specialize in the production of LED lighting suitable for hospital companies are not many.
It is understood that the hospital made LED lighting enterprises are 100% Technology Co. , CREP optoelectronics, photovoltaic cells and other Japanese companies . Philips, Osram, NVC, three male and other famous enterprises have also involves hospital lighting projects , but relatively few emerging LED lighting companies , these well-known companies are not dominant .
"Although China's LED industry is developing rapidly , but the brand concentration is not high , the domestic LED does not form some well-known brands , NVC , PAK and other companies also dominate the party in the traditional lighting, but LED technology is almost and other emerging LED enterprises in parallel position . " anonymity of an LED corporate general manager told reporters.
Also, therefore , whether a company has a reputation for customer choice has little effect . It is reported that the quality of products , prices and constraints of both contract customers main factors affecting the choice of products .
In terms of product quality , relative to the normal functional lighting , hospital lighting illumination environments that require more stringent , being so choose better quality products will become inevitable. Shanghai Kai Rui Technology Development Co., Ltd. for a project official said , out of consideration the needs of China 's LED lighting industry will strive to package high-end products and product upgrades direction of the light source .
Any purchase , the price can not be ignored is its element , hospital lighting the same. Difference in quality is not the case , on the trading price of the product plays a decisive impact.
For example, last year, Shenzhen Nanshan People's Hospital, LED energy-saving projects in the transformation process, companies Lehman optoelectronics, 100% Technology Co. , CREP Optoelectronics , Yu Long Tongfang Technology Co., Ltd., are involved in the bid , although competitors are very strong, but 100% Technology Co., eventually 807,950 yuan of the lowest bid .
In addition, the direction of the hospital as an important marketing channel LED engineering contract is reasonable also affect the trading behavior of both sides. "Although the factors affecting hospital lighting very much, but because the hospital renovation projects are generally larger , and the transformation period is relatively long, so once formed partnership , after a two-way cooperation will be more stable , LED lighting companies to before so it will not passive . " Wei Zhiguo said.
Strong limitations
On the use of functions, compared with ordinary civil hospital lighting requirements necessary to consider a variety of treatments , but also consider the patient's response to lighting conditions , so as much as possible to create a harmonious and comfortable place for patients with medical training to become a The main task.
In addition , many hospital departments , large differences in illumination requirements , general lighting , partial lighting , special lighting and other places indicate different functions but also because of different requirements , needs fully into account.
It is understood that the medical hospital lighting including LED lighting and general illumination functional range mainly used for each area includes the wards , operating rooms, waiting rooms and the like.
Shadowless operation , inspection lights, a variety of indoor lighting and so is the hospital routine and necessary lighting.
Medical lighting mainly attributable to the medical device industry , since China started relatively late night time , and therefore production, the overall technological level is relatively low , only a small part of the production of such products , most hospitals with medical lighting products are purchased from abroad. In addition , due to the complexity of medical lighting products certification program , so the progress of LED medical lighting is not ideal , is incompatible with the demand .
In functional lighting products, although there is a strong research and development and production capacity, but because they are not attributable to the medical device industry , the lack of entry- way . Positive result, many hospitals during the transformation process, although the use of LED products , but mostly concentrated in the waiting area and other areas , and other areas like the operating table is still the main use of high CRI traditional halogen lamps .
" Shadowless operating table for the request , including brightness and CRI , shadowless luminosity must be high for CRI requirements must also be 95 or more, and in the light fades consistency , not biased , just maybe , when some lamps use significantly means and brightness can meet the requirements, but after several months of use , prone to light dimmed , significantly weakening phenomenon means . " the general manager of Shenzhen Rui Optoelectronics Co., Ltd. Liu Shan said .
Liu Shan believes a product from R & D to sales market requires at least one cycle of a year or even three to five years , in order to determine if this is not feasible. In use LED shadowless operating table above is still in a preliminary stage of development , not fully put into use, so the hospital put into use to a wide range of LED lamps is also seen.

LED lighting channels gone?
Since the New Year , I visited dozens of LED lighting business. For
the current development of China's LED lighting industry , general
awareness of the business is ! " More cruel " More ! " Fierce " , "
market is more universal ," and there are questions in this series of
exclamation points behind Enterprise: ! Channels gone? Why this question
? because there are a lot of LED lighting companies have yet to find
their own way , and even many companies ' channel' understanding of the
term , are still in the shallow " agent" , " dealer" level . When the
nature of business-to "channel " the lack of understanding of the time,
naturally, difficult to pinpoint their location , it is inevitable issue
" channels gone? " Questions .
What is a "channel " ? Popular understanding , is the " ditches and roads ," the saying . Ditches is what to do with ? Was the water upstream , downstream drainage to go . The road is what to do with ? Place is a place to connect with another . ? Regarding how to dig ditches and build roads how no fixed pattern , did not say a person , an enterprise must use some way to dig ditches, build roads ; ? Did not limit a person, a company can only dig a ditches , build a road . So that LED lighting business "channel " and , in the end what it should contain ? I believe that any kind of LED lighting companies to sell their products to consumers in the way , is a channel. Popular in accordance with industry classification, should have distribution channels, channel engineering , retail channels, the electricity supplier channels , EMC channel super channels , etc. . These channels require carriers, such as distributors, contractors , retailers, electronic business platform , energy companies , shopping malls and supermarkets. The current "storm channels of " LED lighting companies , is looking confused I do not know what kind of carrier. Business is multi-faceted , multi- channel carrier also faces . Many companies simply will LED lighting professional lighting business currently on the market understood as " the flow of business ," a very one-sided .
In fact, the Chinese lighting industry's best dealer , which is not fully developed? Liu with light , Zeng Ping , Liu Mingxian , Wal- Ren Zhang , Shen Wei Yang, Su Hengbing , Xiao Wenbin ...... they not only have a strong distribution capabilities in circulation in the local market, but also PR has a very strong engineering capability ; they not only have a beautiful store, also has an experienced team . You can use the simple " wholesaler" , " Contractors " " retailer" to define them? Therefore , I believe that " channels gone? " There is a false proposition ! LED lighting companies, you think, or do not want , the channel there, an enterprise will not be exclusive , it will not be a person exclusive ! can have channels, ultimately depends on whether the business enterprise and "like-minded " !

The road is what to do with ? Place is a place to connect with another . ? Regarding how to dig ditches and build roads how no fixed pattern , did not say a person , an enterprise must use some way to dig ditches, build roads ; ? Did not limit a person, a company can only dig a ditches , build a road . So that LED lighting business "channel " and , in the end what it should contain ? I believe that any kind of LED lighting companies to sell their products to consumers in the way , is a channel. Popular in accordance with industry classification, should have distribution channels, channel engineering , retail channels, the electricity supplier channels , EMC channel super channels , etc. . These channels require carriers, such as distributors, contractors , retailers, electronic business platform , energy companies , shopping malls and supermarkets. The current "storm channels of " LED lighting companies , is looking confused I do not know what kind of carrier. Business is multi-faceted , multi- channel carrier also faces . Many companies simply will LED lighting professional lighting business currently on the market understood as " the flow of business ," a very one-sided .
In fact, the Chinese lighting industry's best dealer , which is not fully developed? Liu with light , Zeng Ping , Liu Mingxian , Wal- Ren Zhang , Shen Wei Yang, Su Hengbing , Xiao Wenbin ...... they not only have a strong distribution capabilities in circulation in the local market, but also PR has a very strong engineering capability ; they not only have a beautiful store, also has an experienced team . You can use the simple " wholesaler" , " Contractors " " retailer" to define them? Therefore , I believe that " channels gone? " There is a false proposition ! LED lighting companies, you think, or do not want , the channel there, an enterprise will not be exclusive , it will not be a person exclusive ! can have channels, ultimately depends on whether the business enterprise and "like-minded " !

LED lighting in commercial lighting applications become increasingly prominent
Today's
society , the increasingly fierce market competition, forcing many
industries not only to provide high quality products and services , but
also to consider the full range of multiple factors from the environment
and store layout , location, etc. , only to meet consumer product use
and visual enjoyment and other aspects of the comprehensive needs to be able to occupy a place in the market among .The
process of lighting as Products crucial detail, ensuring basic lighting
stores outside the shop , but also to strive for perfection in this
regard. Reasonable to add lighting elements are often the product will be the
most beautiful side out , tend to improve the grade of the entire store ,
the first time to attract the eyes of consumers and get their favor, so
that the linear product sales rose .
Well-known brand of men Saar . Juarez lighting in the lighting arrangement would achieve the ultimate , so to get such a good development in the years before . It is reported that , Sal . Juarez at the top of the store , use the form Ye 24WLED track lighting , and costume exhibition at the counter , in order to show better results Saar . Juarez selected 12WLED downlights , light exposure makes each side of the garment can be best presented in front of the customer. LED lamps use only the largest operational cost savings store , customers will not cause too full of feeling beautiful, can naturally restore the most authentic product styles and colors.
But Ye lighting was also here to remind businesses, not every shop should use the same wattage LED lamps and specifications must be in accordance with the requirements of the product itself or the shop itself to consider the details of the layout and design of lighting on . With China's urbanization process is becoming increasingly faster, more and more companies began to pay attention to the store or the overall effect , led commercial lighting plays a very important role in the competition in the market , whether it is standing tall on the street , or the introduction of products require attention to make them more appropriate lighting to the glitz , this truth is not only in our country, placed in the world is the same effect.
A person in charge of lighting was Ye pointed out how best to save costs and resources companies , and how to be truly sustainable development has become an important issue in the enterprise must be in the select led lighting fixtures than using traditional incandescent lamps , can save more than half of the electricity. And led lamps using a cold light source, while showing the product , to ensure that the physical state of the product , does not affect the quality of the product occurs , again also to ensure safety.
Today, the world 's increasingly competitive market led lighting technology , open, and how to choose high-quality products in the complicated brands, not just the need for a comprehensive and integrated product comparison , but also according to their actual situation of businesses to thinking.

Experts Weapon : LED life how to predict
Life LED products can predict it? Xiaobian
tell you, even though LED lighting with energy saving, environmental
protection, long life, easy to control, maintenance , etc. , but the
irony is that we often heard the LED drive power of life itself becomes a
direct drag on LED lighting not
"longevity " greatly increased maintenance / cost ; or drive efficiency
is not high power LED lighting leads to energy efficiency conversion
ratio is not quite so high , or because the output current ripple is not
well controlled affect the luminous quality , making green energy-saving advantages of
LED lighting greatly reduced , and even affect the market penetration .
Everything has happened , development and demise of the process, although compared to the average light-emitting devices , led strip life is relatively long, but also have a certain life . Early LED just flashlights, lamp kind of gift , not a long time with a life problem is not prominent. But now LED has begun to be widely used among outdoor and indoor lighting , especially in high-power LED lights, its power, heat , long working hours, life issues will be very prominent. Theoretically be 100,000 hours of life, but in fact it can not be conceivable , then in the end the problem is where?
If you do not consider the failure of the power supply and driver ,flexible led strip lifetime performance for its light failure , which is a long time, the brightness is getting darker , until finally extinguished. Attenuation is usually defined as 30% of its life time .

The five factors influencing the light brightness
In
Shenzhen, the largest city in this weather , we will feel the dust in
the summer than adequate rainfall significantly more air dry, dust
intrusion , light to dark, the logo is not a lot ? Fine
weather at night , walking to the way many people , your advertising
light than other people is not to have an absolute advantage ? Creativity
does not say, and the brightness can affect your advertising effect ,
LED luminous characters , LED lights piercing , full-color lights and
other exposed nothing more than to have eye-catching advantage, a strong
visual impact , it all themselves , so in order to attract guests . About five big points affect the brightness of the light-emitting logo
, are summarized as follows : You can look through the following
comparison , is not it should take action to improve it!
First , LED lamp wears well luminometer word number, type , light output , color, and light boxes in its position will affect the brightness , the premise must be considered to make this point .
Second, identification of the light emitting material ( perforated exposed light color ) : The acrylic plate with a light transmission , light reflection , light absorption and diffusion factors all influence the choice of material , when the light transparency as possible to ensure a certain quality a good degree .
Third, the size of the light box , in particular with a light box in thickness and reflection factor of the light box or other coating material attached towel .
Fourth, the impact of light absorption and electrical equipment boxes inside the lamp brightness of the LED logo .
Finally maintenance : the light output intensity will increase the useful life of the light box and the impact of the accumulation of dust inside the weakened proposal in this regard is for everyone to be able to do a clean case in accordance with the Code must be clean to do this well, in addition under the light output of the lamp is not strong necessary conditions should be done to replace the handle .

LED Grow Light : no sunlight but looks pretty
All things grow by the sun , the truth might be changed. In agriculture park , a "bath " with dark red and blue light, nursery
room , rows of led grow lights to attract the attention of reporters .
"LED Grow Light is a LED (light emitting diode ) as the light source instead of sunlight for photosynthesis, plant growth lamps provide when controlled by adjusting the light quality plant morphology , with shorter flowering plants , so plant water more nutritional value higher, " Qin Long modern ecological agriculture garden greenhouses intelligent and creative engineers Heyan Liang said , LED grow lights is an important technology in the field of vegetable cultivation . "There is no sunlight , but looks pretty ," He Yanliang explained that absorb sunlight and vegetables grown only in red-orange and blue-violet light , low light energy utilization , greatly influenced by the natural environment . The LED grow light can be adjusted spectrum , plant leaves on long stems needed more blue vegetable species and growth stages , the result is more red flowers . Otherwise require 50 days to 60 days to grow into lettuce , using LED grow lights can mature only 20 days .
College of Agriculture , Nanjing Agricultural University , Professor Xu Zhigang said , "LED Grow Light be industrialized breeding , advantages over conventional light sources , traditional light sources 0.5 kilowatts per square meter , while the LED only 0.27 kilowatts , enabling consumption decreased by about half . " He believes , LED grow lights there is a great extension of the space can be used for physical control of agricultural pests , led light with specific wavelengths kill pests.
