At present, China has included semiconductor LED lighting in the medium and long-term science and technology development plan, and has initially formed an industrial chain of epitaxial wafer production, chip preparation, package integration and LED application. Under the current opportunity, independent innovation is particularly important. Professor Zhao Haitian of the School of Architecture and Urban Planning of Shenzhen University used LED street lights to analyze the feasibility of independent innovation through question and answer.
Is independent innovation feasible?
The semiconductor lighting industry supported by the government is an opportunity for great development. Many companies are optimistic about the development space of this sunrise industry. At present, LED application and research and development mainly use LED and traditional light source for simple replacement. Almost all LED manufacturers follow the design idea of ​​traditional street lamps, and pursue tens of watts and hundreds of watts of high-power LED street lamps to meet current HPS lamps. The modeling and installation methods are identical or compatible, and the current LED street lamps and installation methods are almost all designed and manufactured according to the "snake head (flat snake head) lamp" suitable for the HPS light source, instead of the LED lighting law as the starting point for research and development.
Is a simple alternative feasible?
Simulation, counterfeiting, and production of various "snake heads" in the shape of conventional lighting lamps. From the perspective of the existing manufacturers of LED street lamps in China, most of them have not produced street lamps, and the technical requirements for street lamp production are relatively vague. Mutual reference imitation, mostly in the shape of conventional traditional "snake head" shape, the rectangular weight and wind resistance of LED street lamps affect the retrofit installation of street lamps, and it is more difficult to compare with conventional gas discharge lamp lamps in optical distribution and maintenance requirements. In particular, the direct use of the owner of the home has been strongly reflected, which has brought difficulties to the application.
Glare problem. Glare is caused by the excessive brightness of the lamp or luminaire directly entering the field of view. The severity of the glare effect depends on the brightness and size of the source, the position of the source within the field of view, the observer's line of sight, the level of illumination, and the reflectance of the room surface. And many other factors, the brightness of the light source is the most important. No matter whether it is high power or low power, if the light distribution process is not good, it is glare. Now, in order to achieve the light effect, many LED lamps use a transparent mask, and the effect is very poor.
Invalid lighting problem. At present, most public spaces such as corridors, walking ladders, parking lots, toilets, elevators, and roads. It is generally based on the transmission of long-time lighting, and these places are sometimes empty, and the electricity is consumed in vain. Therefore, the most energy-saving technology is not on the wattage of the lamp, but how to make the lamp smarter and more human. When no one is using it, you can enter the "sleep" state, and some people will slowly wake up.
Visibility issues. The zebra crossing effect and the environment in which the air pollution is severe, rainy and foggy, causing the light to be bright on the ground, therefore, the most important main attack is to reduce the energy consumption without affecting the ultimate goal of illumination visibility. The direction is to try to improve the overall uniformity of the lighting. With good total illumination uniformity, the average brightness of the illumination can be appropriately reduced, so that the same recognition and recognition of the visual effect of the object can be achieved, and at the same time, the purpose of energy saving and consumption reduction can be achieved.
The facts show that replacing the HPS light source with an LED light source is not a change in illumination mode, and it is impossible to solve the problem of the high-level illumination mode.
What is the independent innovation of LED?
The first is the research of technologies such as upstream chips in LEDs. As the world's largest lighting market, China's LED mid-stream technology link has become a serious injury. Many domestic manufacturers lack core technologies, and their investment in innovation and research and development is very small, leading to the long-term monopoly of LED key technologies. Without technology, there is no way out. It is a stupid effort to invest in a frenzied irresponsible mass production movement, resulting in negative effects such as overcapacity and poor quality.
The second is the study of LED related standards. As a new lighting product that is attracting attention, how to use the LED light source to meet the application requirements is a major issue facing LED lighting products. To solve this problem, we should begin to understand the basic principles of the luminaire standard from the understanding of the existing luminaire standard system. When we look at the characteristics of the LED luminaire from a scientific perspective, we will understand that the existing luminaire standard has covered the LED luminaire. Due to some characteristics of LED lamps, additional requirements for LED lamps are required, and special requirements for LED lamps are required.
What restricts independent innovation?
Impetuous is a natural enemy of independent innovation, too quick and quick.
Impetuous performance in terms of products. At present, LED application and research and development mainly use LED and traditional light source for simple replacement. Following the design idea of ​​traditional street lamp, the LED light source can simply replace the traditional light source, and the advantage of LED can not be played well.
Impetuous performance in research. Nowadays, relying on the technology development model of the company alone, it is difficult to adapt to the ever-changing market environment. It must be integrated with all enterprises and institutions in the upstream and downstream of the industry to jointly establish an "innovation chain" for R&D and even the entire industry. Technological innovation.
Impetuous performance in the media. Many media can't really grasp the development trend of the industry. They like to exaggerate the development of the industry, so that enterprises in the industry can not really understand the development of the industry and make wrong judgments.
Therefore, the LED industry is a strategic emerging industry, and there is still a long way to go. In the process of industrial development, there will naturally be problems in the system, concept, technology, market, etc., which requires both the enterprise’s own efforts and the needs of each. Aspects give attention, attention and support. The LED industry is an industry with great development potential. We are confident to face challenges, be brave in innovation, strengthen cooperation, deepen application, guide the healthy and sustainable development of the LED industry, and promote the LED industry in China to become bigger and stronger.
