In the a certain shopping malls of the Guangzhou, Miss Song Standing on the before the lamps and lanterns shelf hesitate on the purchase of the energy-saving lamps or LED lamp for a long time, and ultimately still to buy a the the the the price is cheaper of the energy-saving lamps. Miss Song said: "LED lights, energy saving and environmental protection, but the price of big brands in the hundreds of hundred dollars too expensive." Due to high prices, low power consumption, long life and other advantages unmatched by other products, but the LED lights have been not large-scale entry to the people at home. LED civilian market penetration rate is only about 5%.

    However, the high price of LED lights situation will soon change. May 7, the Ministry of Science and Technology issued a semiconductor lighting technology development "12th Five-Year" special plan (draft) "(hereinafter referred to as the" Plan "), which, in 2015, more than 80% of the chip localization of the target cause for concern, if the target can be achieved, the LED lighting is expected to significantly lower prices, and open a huge civilian market.

    The high prices hinder civil promotion of LED lighting

    The data show that replace the traditional 60-watt incandescent bulbs 5-watt LED bulb, the average retail price in December last year, began to decline in the average selling price of a single month decline of 16%, the lowest price of $ 18.9 ($ 118.9 yuan RMB). Replace the traditional 40-watt incandescent bulb 3-watt LED bulb category, manufacturers of the products the lowest market price of 11.1 U.S. dollars (about 69.97 yuan).

    Insiders calculations, a 5-watt LED bulb price of U.S. $ 18.9 million ($ 118.9 yuan), the average life expectancy of about 50,000 hours, if the eight districts of Guangzhou City residential tariff of 0.61 yuan / watt , the use of LED light for 50,000 hours of lighting use costs about 270 yuan. The price of the 60-watt incandescent about 3 yuan, can the average life expectancy of 1500 hours, the same conditions, the use of incandescent lamps cost about 1932 yuan. A major factor to hinder large-scale application of LED lighting products is the price, reduce the cost to promote LED lighting products to accelerate the popularity of "president of the Guangdong Provincial Association of Lighting Jian said so.

LED lighting, LED lighting, a semiconductor light-emitting the original, with a high electro-optical efficiency, small size, long life, low voltage, energy saving and environmental protection, etc., in today\\ s society should strengthen its research to better serve the community.

1, LED lighting technology

LED is a new light, incandescent, fluorescent, high pressure gas discharge lamp, after the fourth generation light source. Early as the 1960s, GE has developed the first visible red LED and a truly historic 2O 1990s, Nichia, Nakamura Shuji Dr. formed by a combination of the various chemical raw materials, the invention of The blue LED, the majority of market demand, with the successful development and commercialization of the white LED in the late 1990s, the LED in various fields have gradually become widespread and popularity.

2, the working principle and characteristics of LED light-emitting diode

The LED is a can convert electrical energy into light energy of the solid components, its structure by the PN junction of the chip electrode and optical systems The basic working principle is an electrical energy into the process of light energy, ie the P-N ultraviolet light, visible light, infrared light is applied to the junction forward current can be issued.

2.1 The luminous efficiency

50-200 lumens / watt LED luminous efficiency will be improved, and its light color, narrow spectrum, no filter can be sent directly to the colored visible. Incandescent, halogen light efficiency l2 ~ 24 lumens / watt fluorescent light 50 to 70 lm / W sodium lamp 90 to 140 lumens / W, most of the power into heat loss. At present, countries in the world are stepping up to improve the efficiency LED light in the near future, the luminous efficiency will be greatly improved, to a certain extent with the traditional light source rival.

2.2 low power consumption

LED single tube power 0.03 ~ O.06 watts, DC drives, single-tube drive voltage of 1.5 ~ 3.5 V, 15 ~ l8 mA current, fast response, can be operated at high frequency. Under the same lighting effects, the power consumption is the eighth of incandescent bulbs, fluorescent tubes of the half.

2.3 Environmental Protection

Do not add \"Mercury\" LED in the production process, do not need to inflatable, no glass enclosure, excellent impact resistance, resistance to shock, not broken, easy to transport, very environmentally friendly, \"green energy\".

 Intelligent lighting industry since entering the Chinese market since the 1990s, the limitations of consumer awareness of the market, the market environment, product price, promotion efforts, and has been in a slow trend.
LED products for home lighting, a unique advantage to create a comfortable and energy-efficient lighting environment through intelligent control. LEDs for its light source determines the characteristics of intelligent lighting direction. National Institute of Standardization, deputy director of Guangdong Province, said Dr. Xu Chen, 3-five years later, when the LED luminous efficiency of limit, the energy-saving effect is no longer the ultimate benefit of the selling point of LED lighting. Future competition in the LED lighting is more reflected in the intelligent demand.

In recent years, many international first-line lighting brands have begun to layout the field of sensing, communications, multimedia and intelligent control. As early as in the first half of 2011, the the Philips Lighting on the have already with Bayer cooperation to\\ s accession to the Ecological Business construction programs which. Through interdisciplinary cooperation, the program provides comprehensive services and material solutions for the construction industry decision-makers in the construction of public and commercial sustainable building. Osram through acquisition of EncELium technology companies last year (The company has state-of-the-art commercial building lighting control software system), aimed at LED lighting control solution. At present, mainland China, although there are some companies have introduced intelligent lighting products, but most only stay in a simple dimming color. In fact, the concept of intelligent lighting much more than that.

LED lighting competition long way to go is reflected in the intelligent demand

Intelligent lighting products currently on the market to achieve intelligent effect by using the control functions of the drive power, the technology itself and there is no difficulty. At the same time, the Chinese market demand for LED intelligent lighting is not high. High institutional research data shows that penetration of the mainland intelligent LED lighting for less than 2%, and product applications are mainly reflected in the dimmable LED landscape light, adjustable color temperature LED street lights and its monitoring and other aspects.

\"At present, mainland enterprises intelligent lighting, mainly LED dimmable the palette lighting products, the real systematic LED intelligent lighting manufacturers, little.\" Zhang Long a new admitted that mainland China LED lighting companies for the intelligent concept not thoroughly understand, mainland enterprises is blind pursuit of the intelligent, focused on the immediate; and intelligent understanding of the international community, mainly from the coordination of people and the environment as a starting point.

 With the unprecedented prosperity of the LED technology, LED display products of concern, widely used in commercial advertising, live broadcast, traffic guidance, the stage interpretation of other fields, the development so far, LED display showing some of its characteristics:
First, the overall industrial development has reached the level of large-scale

The main products of China\\ s LED display industry is not only an absolute market in the country, occupy a certain share in the global market, the formation of a stable export. With significant improvements in product quality and reliability of the overall domestic LED display applications enterprises in major projects and construction of key projects performance to compete in the international market, large-scale display systems engineering to undertake the implementation of the capacity significantly increased.

Second, the industry, technological advancement, technological innovation has played a leading role in promoting the development of the industry

LED display applications industry, the overall technical level of the basic sync with the international development of the past two years, innovative products continue to come, active technical innovation within the industry, product and technology development capabilities continue to strengthen. Meet specific application requirements of technology development, technical support and technology to ensure the empowerment of key technologies and mainstream product development is more mature.

LED upstream industrial development on the display application development of the industry to promote the role of apparent

Positive interaction between the upstream and downstream of the LED industry chain, new products, rapid application of new technologies to promote the development of the LED chip material, driver IC, control technology, many companies in the industry in LED applications, semiconductor lighting, lighting, lighting engineering and other aspects of the technical basis and production engineering basis. Traditional LED large screen display technologies and products based on the LED display products in the industry market share is increasing every year.

Industrial development were the characteristics of standardized, intensive

LED display industry association has been actively promoting the products and technological exchanges and carry out the standardization work, product technical standards, product testing and other means to effectively promote the development of industry standardization. Normalization and standardization led to enhance the level of industrialization, the accumulation effect of industrial layout reflected the focus on larger-scale enterprises such as Shenzhen. In recent years, China\\ s LED display An important feature of the process of application development of the industry is to scale the number of firms increased significantly, the number of medium-sized enterprises is a decrease in the number of small-scale enterprises have also increased. Industry in general by \"olive\" to \"dumbbell-shaped\" change.

The effect of five major activities of industrial development, driven by mentioning

2008, 2009, industrial growth, the pull factors of the major events of the Beijing Olympic Games, the 60th anniversary celebrations, the Shanghai World Expo can not be ignored. In this regard, on the one hand, have a rational understanding, on the other hand to take this opportunity to seriously sum up experience, and actively promote technological innovation, develop new markets in order to maintain the continued development of the industry.

Six, industry structure adjustment and constantly improve and rationalize

Specialization within the industry has become increasingly evident, the prototype of the LED display industry chain has basically taken shape, and laid a good foundation for the escalation of the industry. Competition, specialization of production, technology development, engineering services, and other aspects of the division of labor in the industry reflected in the market segments and prominent core competitiveness, and become the new focus of many companies.

With the increasingly serious problem of Earth s greenhouse gas emissions, approaching the critical point of the Earth self-regulation, countries have introduced policies to governments around the world, including China, is necessary for the urgent implementation of energy saving and emission reduction (carbon dioxide), the LED lights are the most energy-efficient green electric light, natural lighting energy saving options, along with the gradual reduction of cost and price of led lights, its popularity is also accelerating, the LED lamp market share of over 50% in 2020 .

Reduce the cost of LED lights

The LED chip occupy the the the the the the the main part of of the LED lights cost, thus lowering the the the main way to of the LED the cost of to is to lower the the the cost of of the LED chip.

LED chip technology the key to development lies in the base material and epitaxial growth techniques. Base material by the traditional materials of sapphire, silicon and silicon carbide, the development of zinc oxide, gallium nitride and other materials. In a few short years, by means of a series of technical improvements, including chip architecture, surface roughening treatment and multiple quantum well structure design, including LED light effects achieved a great breakthrough.

Low cost silicon substrate technology continue to progress, but the luminous efficiency are still not satisfied, to maintain this pace of development, once they reach a higher level, the silicon substrate as the main technical program has become an inevitable choice, businesses will also be huge economic returns.

Improve the luminous efficiency of LED lights

Five elements that determine the direction of technological development of LED lights

Improve the light efficiency can also improve the proportion of the effective light to start. Light thin-film chip technology can reduce the light output of each side of the loss, with the bottom of the reflecting surface of more than 97% of the light from the front output power conversion be mostly light, not only significantly improve the LED luminous efficiency, a favorable favorable conditions for the lens design. The thin-film chip technology is the core technology of super bright LED chip production.

Improve the color of the LED lights

In the high-brightness white LED, a small portion of blue Stokes shift of the longer wavelengths. This is a good thing, because it makes the LED light manufacturers can use many different colors of the phosphor layer to extend the emission spectrum, effectively improve the LED color rendering index (CRI). Using phosphor white LED high CRI has a cost, because the Stokes shift will cause the white LED efficiency is lower than the efficiency of monochromatic LED. But for most lighting applications, preferring to use high CRI LED light efficiency is slightly lower.

Improve the efficiency of the LED lamp power

Whether the power of the current-limited constant current control, or op amp to control the constant current power supply, we must solve the supply problem. Switching power supply chip work is a relatively stable DC voltage for the chip-powered, the chip s operating current of several MA ranging from an MA. Like FSD200, NCP1012, and HV9910, such a chip is a high-pressure self-feed, to use is convenient, but high-pressure feed, resulting in the rise of the IC heat, because the IC to withstand about 300V DC, a little current, even if MA, the damage of 0.3 watts consumption. General LED power about 10 watts, the loss of a few tenths of watts can click on the efficiency of the power to pull down a few points. Typical elephant QX9910. Resistor pull-down to take power, so, the loss on the resistor, about have to loss it a few tenths of watts. There is a magnetic coupling transformer, plus a winding on the main power coil, as flyback power auxiliary winding, to avoid loss out of a few tenths of watts of power. This is why one of the isolated power supply is also used transformer, in order to avoid the loss of a few tenths of watts of power and efficiency to mention a few points.

Improve the system reliability of LED lights

The overall efficiency of the LED life and reliability through system optimization can be improved.

Light source: compact, efficient, and to choose the right color and output power.

Control and drive: the use of electronic circuits to achieve constant current LED driver and control.

Thermal Management: To achieve a longer life must control the use of LED junction temperature, thermal model calculations with the new materials, new technology is the hot spot of LED lamp technology.

Optical components: lenses, reflectors or light-material light rays are focused in the target area or dispersed in four weeks, according to design requirements.

With the rapid development of LED technology, and gradually increase the efficiency of LED light, LED lamp applications will be more extensive. Especially with the worsening of the global energy shortage problem, the LED lights will replace the inevitable choice of incandescent, tungsten and fluorescent. In addition, the interior lighting design, the LED will tend to intelligent, diverse, and the arts.

"The current market of LED lighting applications, there is no uniform product standards, a manufacturers products are completely compatible with another manufacturer, it has become a major obstacle in the development of led lighting industry." Exchange Conference in Foshan, the first LED lighting industry, and more business representatives unanimously recommended, Foshan should guide enterprises to establish a unified product standards as soon as possible.

Foshan Science and Technology, Deputy Secretary the Huangqi Feng said, the second batch of LED industry in Guangdong Province special support fund of 450 million yuan, five large projects in Foshan, Akinobu magnitude is one of them, a total capital of about $ 160 million.

Enterprises: the construction of a unified standard required the government guidance "

100 yuan worth of LED lamp is damaged, only replace $ 8,000 worth of LED street lamp. "The conference, OSRAM (China) Lighting Co., Ltd., director of solid-state lighting products market Guan Shi Jing said, due to the different LED manufacturers of lighting products are not mutually compatible, once a part of the product problems and can not find the original manufacturer, the entire product can only be scrapped, which makes the products and parts replacement LED lighting market very difficult.

Exchange site agree that many companies on behalf of this view of Guan Shi King. Came from Shenzhen to attend the General Assembly Shenzhen Hua Gaoguang Power Technology Co., Ltd. general manager Mr. Fu said that the products are not standardized, it is difficult to strict than the products of different manufacturers. Manufacturers not in the product life, color temperature, cost competitive, but they played the "price war". But the cost of LED lighting products is difficult to decline, in order to reduce product prices, many manufacturers produce products difficult to have quality assurance. "The process of establishing product standards of the relevant government departments should play a leading role, and this standard should be established as soon as possible."

Cooperation: "The needs of large enterprises first step"

Large enterprises and SMEs for the LED industry set up exchanges and cooperation platform to complement each other, is one of the main purpose of this exchange. But reporters at the scene was found of the interview, hesitates for cooperation, leading enterprises and SMEs.

Blue Arrow Electronics LED Division Manager Luo Jijun told reporters, "season orders too much, we do not busy, the need of SMEs for our OEM support, but really looking for small businesses to help production, we are very worried about the quality of products, technologies outflows, in serious cases may even damage our brand. "Luo Jijun, the cooperation of large enterprises and small businesses need a high degree of trust, which requires the two sides in technology, management, long-term running.

Huagao Guang Technology Co., Ltd general manager Mr. Fu also admitted that there are channels of large enterprises, financial strength, brand, and the lack of advantages of these are small enterprises. However, "when dealing with small businesses, large enterprises are too strong, for example, of the purchase price of the small businesses of large enterprises will pressure a few months, not sufficient working capital for small businesses, which may be a fatal blow." Mr. Fu think, to cooperate in large enterprises need to take a step in the capital and other support for small businesses.

In this regard, Foshan Lighting Association, Wu Yulin, Foshan LED lighting manufacturer has many years of industrial base, technology, leading enterprises to cooperate with the biggest benefit is able to quickly get the products of large enterprises have strict quality monitoring system to small businesses to do the training, the two sides cooperation is feasible. "He disclosed that the gesture of goodwill, Osram, the company has docking way attached to the meeting information, I believe that will be followed by many small and medium enterprises docking, is expected to form the order.

In view of the small businesses is weaker in the other aspects of product design, the Congress, Foshan Lighting Association and Guangdong Light Industry Vocational and Technical Institute College of Art, Guangdong Institute of Textile Technology, Shunde Polytechnic Institute of Technology signed a "common build LED lighting design trading platform for strategic partner "agreement, in order to provide low-cost lamps industrial design patent.

29.9 yuan technical support price cuts

Upstream chip, the sapphire substrate, the relative excess capacity, coupled with lower lighting applications, delay start, leading to electronic semiconductor industry growth is slowing down this year. Many the company 捂紧 purse dismally dilemma, BDO Runda not by common sense out the card, played a trick of big price cuts, the first international after the combination punches.

October 18, BDO Runda in Beijing launched a relying on a patent duct cooling system LED innovative products in the Chinese market instead of 7W energy saving lamp 3W specifications of LED lamps retail price of 29.9 yuan, and Philips energy-saving The lamp 28 prices were unchanged. LED lights, energy saving of 50%, better than 10 times longer life of the energy-saving lamps and mercury-free pollution obvious advantages.

The day, BDO the Runda also announced a core argument is 4545/350Mat 1101M / W high-power chips in similar products, BDO Runda production, the high-power chip has reached international advanced level.

\"We believe that once the price barriers by 29.9 yuan crack lighting will quickly enter the LED era. Semiconductor industry always gives surprise at this price a very good profit.\" Wang Dong-lei, smiling, told reporters, \"must sold for the price and quality of consumer recognition, to an LED bulb is designed to be very beautiful necklace as 100 dollars to sell, I would like, but consumers do not buy it, consumers can buy a table lamp, a floor lamp as works of art, but No one will buy a Bulb as works of art. \"

Wang Dong-lei calculations, in accordance with the current pace of development of the domestic LED industry, and domestic metal organic chemical vapor deposition (MOCVD) equipment arrival and put into operation in progress, accompanied by the development of new products such as BDO Runda, LED light source to the end of this year to $ 1 per watt, while the price is still 1.2-1.5 times the price of energy-saving lamps, but when the LED products with energy saving lamps spread of only 1.2 times the LED lighting market will suddenly zoom , it is estimated that energy-saving lamps to replace the rate will reach 10%, while the replacement rate of the U.S. and European markets will reach 50%.

Having said that, the reporter found that the domestic LED lighting market 5W Bulb sold about $ 30 everywhere, even to around $ 20, many shops, many customers in actual use, known life of up to tens of thousands of hours or even a lifetime is not a bad product, was soon broken for various reasons, in fact, the main product technical performance standards caused.

\"BDO Runda do, there is no technical support for lower prices.\" Said Wang Dong-lei, the company built a 7 LED Division, flower hired from the United States, Japan, Korea, China, Taiwan, the world\\ s outstanding LED talent determined to create the world\\ s one of the best LED products. \"Today, we are in the high-power chips is leading this thing is for sure, but we need to find ways to keep this lead.\"

To break the price barrier, BDO Runda Electrolux, the world\\ s top 500 enterprises reached a strategic cooperation, the company provides technology, design and manufacturing support, Electrolux offers its high-end brands AEG. This cooperation is mainly to Europe and the United States market and the gradual penetration of the global market.

Capacity is really a surplus?

The entire LED industry is filled with overcapacity argument, winter on the recognition of the many industry professionals, this can also be from the LED-related stocks this year, the trend is not difficult to see.

\"A few months ago, who do it will be the brightest thing can make money.\" Wang Dong-lei ridicule. He said that the LED chip from the grab in short supply to the overcapacity, global TV LED backlight LCD TV sales have fallen by about 50%, making the backlight used in chip production capacity, all of a sudden put into the LED lighting market, lighting market, an increase of 30%, but could not absorb, resulting in a short-term market fluctuations. \"For LED production capacity is a good thing, not a bad thing, it will be the pursuit of profits speculators kick, chip prices more civilians, the entire industry to mature.\"

In a pre-dawn darkness of the night, BDO Runda LED industry capacity expansion force.

In November last year, the company raised 1.5 billion yuan to invest in the manufacture of Wuhu LED chip, LED packaging and LED lighting three projects; October 13 this year, the company received for the production project of Wuhu LED epitaxial wafers and liquidity of $ 3.5 billion private placement approval of the program after the completion of the scheduled increase, BDO Runda will form the strategic layout of the LED industry, epitaxial wafers, chip, package, lighting applications open value chain.

5 billion yuan to invest in LED upstream requires a lot of courage, but also need to face all kinds of questionable sound, the whole industry chain will cause everywhere is the situation of the competitors, but rarely collaborators?

Collaborators? This is definitely a fallacy. \"Explained Wang Dong-lei from the BDO 润达 industry chain itself, on the one hand, towards integration, on the other hand is open. \"For example, the chips produced will be sold to someone else, and we have to buy someone else\\ s chip, we are the largest buyers of the Philips chip. Chip characteristics are not the same as the lighting needs of different density, we can not supply us with applications all the chips. \"

Wang Dong-lei, LED future strategy will only exist in two directions has been done, one from the chip package, so that the light engine, the second down to do the application. \"If you only do light engine, the industry chain is shorter, the overdraft is difficult to support. Enterprises to ensure that the chip is the world\\ s most cost-effective, if not immediately be eliminated. If you do the application have the support of the brand and the arts, even the short term a little bit difficult, the same a light bulb can be sold for 15 dollars, but also can be sold for 20 dollars, the whole industry chain a safer, more controllable, so the strategy of vertical integration BDO Runda very careful decisions. \"

The inside of our entire investment package of investment is at least only a few a little package in the industry chain of no value to the idea to throw away, this is the real cost reduction. \"Said Wang Dong-lei.

Industry statistics show that the mainland of China has more than 10,000 lighting company, total sales of the three companies in the industry accounted for only 2.5% of the total sales of lighting products in the Mainland, the focus of competition have focused on LED lighting.

To do the electrical state of mind to do LED

Wang Dong-lei \"bread king\", who in the end what cards? He odds geometry in the LED industry?

\"Why do we do the LEDs, we do not to do LED of the LED, LED is the next generation of human lighting industry, a few basic properties of the next generation of human lighting products, we have to do it.\" Said Wang Dong-lei, \" we do the LED to do the electrical state of mind, in my opinion, who should be able to meet consumer demand, whoever wins. \"BDO Runda small appliances known around the world, the pursuit of one of the best brand model resulted in the company bread accounted for more than half of the world market, coffee maker accounted for 15% to 25%, ovens accounted for 20% of the market, the company formed the open, to the integration of industrial chain model.

Led road lighting should continue to engage, LED road lighting applications in the Chinese market a few years, has a certain basis, should be concerned about product development in the promotion at the same time, improve product cost-effective to solve the problem of cooling and other applications based on truly meet the lighting needs of the users. \"a veteran in the industry would look at the LED lighting market and development priorities. At present, the industry\\ s concern for the LED lighting toward more in-depth, more humane to meet safety and comfort of the direction of development. November 9, 2011 Summit, one of the 8th China International Semiconductor Lighting Forum LED street lighting market and technology application be held as scheduled from the domestic and foreign experts, academics, entrepreneurs, etc. LED lighting development status, technology and the industrial development trend, the need to focus on the problem, how to play to the advantages of the LED light source through a more scientific and rational design, in interaction with the environment to achieve a more secure, comfortable road lights have become the key topic of the meeting.

Speakers of this conference Geng Bo, Deputy Secretary-General of the National Semiconductor Lighting Project R & D and Industry Alliance, Taiwan\\ s Industrial Technology Research Institute of the electro-optical components and systems applications department at Zhu catechumens, Germany University School of Architecture of the University of British Xie Erfei lighting and visual perception Professor Steve Fotios, Philips Lumileds Lighting Company in Asia Marketing Director Zhou Xuejun, Philips Lighting Asia, senior research fellow, Zhu Xiaoyan, Guangdong Long Traffic Technology Co., Ltd., chairman of Chen Bin, Fudan University, the light source and lighting engineering associate professor Lin Yandan, etc., made a keynote report . From a different point of view of the road lighting market and technical issues of road lighting applications.

Geng Bo from the perspective of industrial development, the development status of the semiconductor road lighting industry, there is the problem and carried out by the Government in terms of road lighting support policy and subsidy policy, issued an important development of the industry data. He pointed out that the 2011 100 cities in the installation of 800,000 LED lighting products, outdoor LED high-mast lighting part of the future will have much room for development.

Zhou Xuejun, director of Asian markets, Philips Lumileds Lighting Company, pointed out that this year\\ s industry forum seems less talking about the topic of road lighting, but in fact, the development of road lighting market compared with last year and the year before showed a steady growth trend, we for the road lighting return to rational expectations of market development, and the same time as the product matures and costs decline further, the LED road lighting market development opportunities to re-emerge.

Zhu catechumens on Taiwan\\ s road lighting market, the development status quo and the government in promoting industrial development of specific measures at the same time he also introduced the five kinds of road lighting with light the way, and pointed out that the use of the light guide device carried out with light may be will become the future development of direction, but is currently facing great technical difficulty.

Lin Yandan CIE conference held this year on the latest research reports and research trends analysis, pointed out that these research directions and research results for the reference and significance of China\\ s semiconductor lighting industry. She pointed out that the domestic LED enterprises should be a deep understanding of the characteristics of the LED light source, making the performance of the LED products based on a scientific basis.

Chen Bin from road lighting, LED tunnel lights and street lamps in the market performance of different phenomena starting from the perspective of the technical applicability and economic applicability of a detailed analysis of its causes. He pointed out that the technical applicability and economic applicability of the product development are achieved, the market will naturally open, and this is the law of the market.

The steve Fotios from the road target recognition, obstacle recognition, face recognition and perception of the environment point of view, the optimal spectrum suitable for pedestrian area lighting. There are also experts and entrepreneurs from the standard testing, lighting design, road lighting, visual comfort, modular point of view to do the report, the development of LED road lighting to the depth, the application of LED lighting to more meet the safety, comfort humanization of the direction of the LED road lighting market toward a broader direction.

led under the baton of industrial policy, and Pushing Hands. Development and Reform Commission, Central Information Secretary, Deputy Director Xie very last week revealed that the Development and Reform Commission is organizing the preparation of semiconductor lighting industry, "the 12th Five-Year Plan, in conjunction with the departments concerned to study to consider LED included in the" Green Lighting Project.

The clash of foreign brands and domestic brands, LED function and decorative market strategic change, and once again become the focus of the game under the policy. In the end who is assigned to the number of LED s largest cake Where? Still smoke and mirrors.

Commercial lighting higher

The end of the Guangzhou International Lighting Exhibition from June to see, in addition to LED exhibiting significant increase in the proportion, and the other changes are also quietly emerged: LED products from decorative gradually to functional changes.

The research firm Strategies Unlimited has a new research, from 2010 to 2011 is the first of the two LED commercial lighting, rapid growth and popularity of take-off, LED home lighting applications have to wait until after the 2011, 2012.

The data show that commercial lighting accounts for the global lighting market electricity consumption 43 percent, the highest proportion of the retail, office, storage purposes, educational buildings, health care applications aggregate of the total commercial lighting electricity consumption 70% of the market.

Relative LED home lighting, commercial lighting market than civil lighting market operation more convenient, mass-market scale of procurement, making LED lighting in the commercial lighting market has been steadily rising, the growth rate significantly.

Investment Advisor in the Research Director Zhang Yan Lin pointed out that far, commercial lighting LED penetration is highest breakdown field of lighting, commercial areas are not price sensitive, this is also the large-scale promotion of one of the reasons.

Undoubtedly, the commercial space lighting in the acceptance of the price easy for LED companies to enter. In addition, with increasingly stringent energy saving requirements, making the LED in the proportion of the use of commercial space increases.

At present, there are about more than half of the existing commercial lighting needs to be replaced in the next three years, the next decade, about 300 million people into cities, the size of the city commercial lighting will further expand the commercial lighting market reverie.

Foreign companies heavily bar, according to

Yang earth brand competition is increasingly intense. Economic and Trade Commission of Guangdong Province authorities admitted that the LED market is large enough so that everyone can eat, but in another two years or even one year, in the end who eats who said do not know.

Indeed, China has become one of the global commercial lighting of the fastest growing market in recent years, annual growth of 20% constitutes a huge commercial lighting market. Although the huge capacity of China s lighting market, many brands, but has been showing a foreign brand a dominant situation.

More critical is the foreign brands use their own technology, capital, sales and other advantages from epitaxy, chip, package, and application of a complete industrial chain, to occupy the key areas of the market.

Habitat technological monopoly advantages of foreign-funded enterprises in the domestic market rapidly enclosure. May 23, covering 100 acres, a total investment of more than 350 million U.S. dollars of Xu Rueiguang LED epitaxial silicon project in the South China Sea, the project by the U.S. SemiLEDs Corporation to jointly invest in the domestic semiconductor lighting industry giants. In marketing, the end of last year, Philips began to set up in the country, to upgrade the commercial lighting center stores, products, but also to provide the overall shop lighting solutions, to provide users with convenient one-stop services to meet different levels of commercial lighting needs.

Now nearly 500 Philips commercial lighting center of the layout of the Chinese. Philips to enter the commercial lighting retail industry is a long-awaited strategic planning. "The relevant person in charge of the Philips commercial lighting.

Spontaneous groping and domestic, and the progressive development of the LED business enterprise started late 2004, slowly, and mainly low-power light source; to 2006 and 2007, the LED business in the exploration period, the pace is quite slow, due to the immaturity of the market and technology, has not not be able to make major strides forward.

In the field of commercial lighting, there are a number of OEM enterprises, mostly small-scale manufacturing enterprises, to concentrate on production, not as basic terminal marketing.

If there is no lighting living room, bedroom color is significantly impaired. So, after the tiles, sanitary ware, cabinet purchase, we non-stop and then approached the lighting.

Speaking of lighting, according to my understanding, each room due to their different functions, requirements are also different. Concrete in accordance with this idea of ??design: the configuration of the living room lamps should be beneficial to create a warm and enthusiastic environment to make guests feel at home.
