LED indoor lighting road is very long, TV backlight patent is a worry
· Entering general lighting should be slower because some technical issues are not well resolved.
· The road to indoor lighting is still very long, and cost is the biggest obstacle.
· The threshold of TV backlight technology is relatively high, the supply chain is relatively closed, and application companies attach importance to patents.
Peng Wanhua: At present, the application of LED should focus on the promotion of backlights, automotive lights and commercial lighting, namely downlights, spotlights, bulbs, commercial fluorescent lamps and freezers, as well as public and special lighting. It should be slower to enter general lighting (offices and homes) because some technical issues, such as light color quality, are not well resolved.
Fang Zhilie: After several years of research and development, LED street lamps have made some progress. It should be said that in the LED street lamp products below 100W, some product life problems have been solved, and the L70 can reach more than 35,000 hours (6000 hours of work attenuation is less than 5.9). %). The LED street lights and tunnel lights of less than 100W tested in multiple tunnels have actually tested the L70 life index to more than 35,000 hours. Even so, it is necessary to strictly control the life and prevent the counterfeit and inferior products from passing through, so that the promotion and application work will achieve positive results, which will be beneficial to the development of the LED street lamp product market.
At present, the research and development of high-power LED street lamps (100W-200W) should be further strengthened to comprehensively capture indicators such as light efficiency, uniformity and longevity. Emphasize the life expectancy of the project and encourage innovative technical measures to improve the life of LED street lamps. Conduct test evaluations of LED street lights including life indicators. The bidding indicator emphasizes the life expectancy and clarifies the responsible party when the life expectancy is not up to standard and the damage is caused by damage and serious decline. I believe that as long as everyone is holding a scientific attitude, scientific research and practical research, application of experiments, will soon solve the life of high-power LED street lights, and then promote the application of LED street lights to the first-class road. In the current situation that the high-power LED street lamp has not passed the life, the LED street lamp application is not promoted for the first-level road lighting. When will you pass the customs and when will you promote?
He Kailuo: The characteristics of the LED market are as follows: The first is that LED backlights are the fastest growing, and LED-backlit LCD TVs will grow 10 times in 2010, from 3.5 million units in 2009 to more than 36 million units in 2010; the second is Automotive lighting, in addition to the headlights, all indicators, signs, lights will use LED; the third is commercial and public lighting, all commercial lighting, more than 12 hours of electricity, supermarkets, underground parking, cold storage, workshops, factories are available LED products, the current 24 hours of electricity lighting places with LED lights 1 to 1.5 years of savings in electricity costs can be recovered, the LED application of commercial lighting in the next three years will exceed 30%.
Wang Li: Overall, the development of the lighting market is relatively fast and may exceed people's original expectations. The application of domestic enterprises' products is relatively mature on the display screen. This is a relatively stable technical threshold for TV backlight products. The supply chain is relatively closed, and application companies pay more attention to patents. Therefore, this market is not easy to enter. The lighting market is widely distributed, high, medium and low, and may develop faster. The possibility of intellectual property disputes in these markets is considered by individuals to be relatively large, especially for backlight products. Due to the small number of production enterprises and the large scale, it is easy to become the object of patent litigation.
Chen Hesheng: Outdoor landscape lighting and street lighting are becoming more mature. Therefore, indoor and outdoor lighting does not have the problem of successive development, but has formed a situation of simultaneous development. Personally believe that the simultaneous promotion of indoor and outdoor lighting means that LEDs are gradually matured in general lighting, and it is of little significance to entangle themselves in household lighting. First, any lighting method has its own advantages and disadvantages. The target of substitution is not practical. Until now, even the candle is still available in the market. Second, compared with the promotion of a new technology, the improvement of the cost performance of the product can have a longer-term process.
Zheng Tiemin: At present, the application of LED backlights has driven the development of the LED industry, so there is a shortage of Blu-ray chips. With the improvement of light efficiency, the next step in the development of the LED industry is indoor lighting. There are five reasons for this: First, the light efficiency is further improved. In theory, the light efficiency can be increased to 200 lm/W, which is actually improved within 3 years. It is ok to 150lm/W. At present, the light effect of Inspur Huaguang applied to the T-type lamp has reached 120lm/W. Second, compared with energy-saving lamps, the price/performance ratio is further improved. With the increase in performance, the cost is further reduced and the price is further reduced. Third, the guidance of the policy. Fourth, there are already thousands of enterprises engaged in the production and preparation of indoor LED lamps in China. Fifth, the United States and other western developed countries have begun to use LED indoor lighting to demonstrate the LED indoor lighting in China.
Lu Hongliang: The cost of LED in LCD backlight is not high, so the replacement is faster; the automotive lighting market is mainly based on auxiliary light source and brake light. The significant advantage of auxiliary light source is energy saving and environmental protection compared with traditional tungsten light. Because LED is a cold light source and the reaction speed is fast, this feature can not be replaced by any existing light source, so the replacement will be very fast; outdoor landscape lighting is more reflected in the changes, color and other advantages, floodlights and The high-brightness lighting products of floodlights are still a constraint in terms of short-term, and commercial lighting should consider the environment and the rationality of use. Energy conservation should consider two aspects: the first is the light effect of the light source itself; the second is to be used reasonably, such as the person walking away from the lamp, reasonable dimming color; the road of indoor lighting is still very long, and the cost is the biggest obstacle.
Review
Based on innovation and promote application
LED applications, especially lighting applications, are growing rapidly, and it is now important to emphasize innovation and science in promoting LED applications. The truth about innovation is obvious. Only innovation can have a foothold in future patent disputes. With the rise of the lighting market and the rapid advancement of the TV backlight field, future patent disputes will be inevitable. With its own core technology, it can stand in the future market competition. At the same time, in the promotion of LED commercial lighting, we must be realistic and gradual. Pay special attention to the reliability and longevity of LED devices. New products with poor reliability and short-lived products will not have any value, but will hinder the promotion of LED applications.
LED standard "can not be relied upon" and "can not rely on" coexist
· LED is a new type of light source, and some standards need to be carefully studied and revised.
· National standards lag behind industry development is a reality, LED lighting is still in the primary development stage.
· The formulation of national standards can not be rushed to seek success, but the speed is not up to speed, you can start from the establishment of industry standards.
An Guoyu: At present, the national standard of the semiconductor lighting industry has lagged behind the development of the industry. Some local standards have obvious characteristics of drafting companies and lack of impartiality. For example, some local standards for LED street lamps stipulate that their light sources must be single 1W, etc., and some also specify the shape of the lens. Such local standards exclude street lamps that use advanced packaging modes and light distribution methods, which not only can not promote the development of the industry, but also play a hindrance role. Therefore, it is imperative to issue national standards as soon as possible to guide the healthy and orderly development of the industry.
He Kaiwei: The lag of LED product standards is a key issue hindering the development of the industry. However, many companies believe that there is no standard, and some enterprises are irresponsible. The lighting, lighting, and construction engineering standardization systems are perfect. The main problem at present is that there are standards that are not implemented, and that there are laws that do not comply, resulting in chaotic situations in which products are mixed and the market is disorderly.
Since LED is a new type of light source, we need to study and formulate some standards carefully. We discuss the standard issues at the following levels: First, lighting is a comprehensive interdisciplinary project that combines technology with human physiological and psychological optical effects. Historically, International standards are developed with the development of light sources. The new optical characteristics of LEDs (such as the combination of color and light with high color saturation) have a great impact on the current standards of CIE (International Commission on Illumination) and IEC (International Electrotechnical Commission). Great investment, organize basic research in photometry, colorimetry and surveying, earnestly carry out research on experimental physics statistics of Chinese people, enhance the right to speak in international standards, and participate in the revision of international standards. Secondly, there are more than a dozen national-level standardization technical committees involved in the formulation of lighting standards in China. They have their own battles. There is no coordination mechanism and mechanism. It is recommended to include LED lighting standards in the national “12th Five-Year Plan†national key standards planning project. The AQSIQ, the National Standards Commission and the China National Institute of Standardization organize various professional standardization technical committees and enterprises and scientific research institutions to jointly study and formulate. Third, the currently urgently needed product standards can be organized and researched by the National Lighting Appliance Standardization Technical Committee to solve the urgent need. Fourth, local governments have set their own industry standards. It is not serious to publish a company's standards as provincial standards. It is mainly in the street lighting industry. There are many provincial and municipal standards, because many street lights are everywhere in the “Ten Cities and Ten Thousand Citiesâ€. Projects, government procurement must be based on standards, so they have introduced LED street lights standards. In fact, according to the standardization method, if there is no national standard product, the enterprise should have its own product enterprise standard, and submit it to the corresponding quality inspection department for record. The product is sent to the third-party testing organization for inspection and the government can purchase it.
Zhang Wansheng: The national standard lags behind the industrial development. This is the reason. LED lighting is still in the immature primary development stage, mainly reflected in the process of setting standards in the Electrical Lighting Standardization Committee and the Semiconductor Lighting Standards Working Group, for example in In terms of terminology definition, test methods and division of labor, different opinions generated by different industries are difficult to unify. However, differences in opinions cannot be resolved by administrative means. It is necessary to test and correct through practice and reach a consensus through a long period of time. This is not a one-off event. The formulation of national standards cannot be rushed to seek success, but the speed of failure is not up to even lead to misleading negative results.
In order to meet the urgent needs of the current development of the LED lighting industry, we can start from the development of industry standards. The lighting electrical standard committee and the semiconductor lighting working group can establish their own standardization systems. Even if there are repetitions and overlaps, it does not matter. There is a dispute over the division of labor. At the same time, the provinces can also formulate relevant local standards. The standards developed afterwards must be more comprehensive and more realistic than the standards first established. There is a comparison, there is identification, local standards should not be afraid of more, afraid of chaos. Local standards and industry standards will lay a solid foundation for the formation of national standards, and have the significance of promoting and drawing on the formulation of national standards.
Li Mantie: The formulation of standards is a gradual process, especially semiconductor lighting is an emerging industry, products are constantly developing, and new technologies are constantly emerging. Standards development cannot be done overnight, and should be gradually improved with the development of the industry. Standard setting is to protect the industry, and it cannot be the threshold set by some enterprises for commercial interests.
Yu Binhai: First, standards play an important role in regulating products, processes, development, and markets. On the one hand, we can give you a clear, unified method, terminology, etc., such as what standards and what kind of equipment to test which performance of LED, etc., everyone has a unified standard will not cause confusion. On the other hand, it can give the market a threshold and regulate market behavior. It will not promote the introduction of some inferior products due to disorderly competition and pure interests. In particular, after the introduction of mandatory standards, market supervision departments should quickly establish Regulatory, access, certification, testing and other systems.
Second, the standard is to be built on relatively mature products or technologies. Otherwise, the development of technology will be limited to some extent. For example, the structure of high-power structure has not been completely determined. If a standard is imposed, the restrictions will affect the development and development of. Generally speaking, the promotion of LED industry standards is more in line with the development of the industry, but the LED market has experienced explosive growth in the past year or two, making the standards relatively lagging behind. We believe that it is imperative to introduce basic norms and standards such as terminology and test methods in order to better regulate the end of the market's disorderly competition. The standards for the appearance of applications and interfaces should not be too urgent, because in fact Most of the LEDs are replacing lamps, and they have not yet played the advantage of being small and controllable. There is a huge amount of space for future applications.
Third, the establishment of the standard system should play a synergy between management, industry, research and research. The standard should not be a one-man show of a certain university or enterprise, nor should it be a smooth road of joy. It is necessary to give full play to the powers of the institutions and enterprises in all links of the industrial chain, and to mobilize multiple superior units to coordinate and tackle the problems in the form of project tasks, fully study and experiment, and fully draw on international standards, especially the US Energy Star and other standard systems.
Fourth, the standard system includes national standards, local standards, and corporate standards. All three are necessary and complementary. Enterprise standards and local standards are important components of the national standards system. Enterprise standards are the specific refinement and embodiment of national and local standards. There are no conflicts or contradictions between them.
