The future of the LED industry is unlimited

Following the overall surge in LED industry stocks in January 2, LED industry stocks have remained strong in the past week. Some analysts predict that LED industry stocks will continue to rise. The LED industry has an infinite future. LED (Light-EmittingDiode)It is short for light emitting diode. As a kind of semiconductor electronic component that can emit light, it has developed rapidly in recent years along with the national phase-out of incandescent lamps.

Deng Maolin, a researcher at the China Lighting Appliances Association, said. The future is infinite and is directly related to the advantages of LED. He Huahua, a consultant researcher at CIC, believes that LED has obvious advantages over incandescent lamps and energy-saving lamps in terms of working life, power consumption, response time, volume, and lack of environmental pollutants such as mercury and lead. These visible advantages have gradually penetrated into the family field from the public sector, and the proportion of household consumption is getting higher and higher. In terms of industry, the effective combination with solar energy conversion further highlights the role of LED in energy conservation and emission reduction in the future. He said. Deng Maolin, a researcher at the China Lighting Appliances Association, also said that the performance of LED lighting products in protecting the environment, energy conservation and emission reduction is self-evident. Generally speaking, in lighting places, ordinary need 8 ~ 9W energy-saving lamp, LED lighting, only need 5W to keep energy-saving lamp 8 ~ The level of 9W is precisely because LED is in light efficiency ( The total luminous flux emitted by the light source and the electric power consumed by the light source (Tile)The ratio of is called the luminous efficiency of the light source. The higher the luminous efficiency value is, the stronger the ability of the lighting equipment to convert electric energy into light energy is, that is, under the condition of providing the same brightness, the energy saving of the lighting equipment is stronger; Under the same power, the lighting property of the lighting equipment is stronger, I . e. the brightness is larger)It has obvious advantages. He explained. At present, in order to regulate the LED market, the country has successively issued 19 LED-related standards. For the introduction of these standards, especially in the face of the booming LED industry in the past two years, he Huabei said, the establishment of these standards will lay a good foundation for the large-scale promotion of LED. The formulation of standards is an important means of industrial optimization and an effective means to regulate the market. As a large manufacturing base for LED application products, China has the opportunity to participate in and lead the formulation of standards, providing a strong backing for LED to enter the international market. He added in China. However, Deng Maolin said that the current entry threshold for the LED industry is low, and some enterprises, especially small workshops, have poor performance and fail to meet the safety standards of 3C certification. At the same time, he believes that in view of the fact that some LED related standards are recommended standards and are not enforced, it is difficult to guarantee that the recommended standard enterprises will not necessarily abide by them. In addition, for the quality standards of LED lighting products, Deng Maolin said that to a certain extent, the performance standards of the products determine the quality of the products. Generally speaking, the quality of products that meet the performance standards will not be bad, except for the products produced by some small workshops I mentioned before. In response to this problem, Cai Jianqi, an associate researcher at the Institute of Public Safety Standardization of the China Institute of Standardization, believes that LED quality standards cannot be generally summarized as whether the product quality is qualified, and multiple factors should be considered. He said that performance indicators and health indicators jointly build quality standards. Only after reaching the performance index, further optimization, improvement of safety requirements, improvement of health requirements, and small harm to human health are the real good quality. Especially now, people pursue visual health. LED quality is actually a potential impact on human health at a deeper level. Cai Jianqi believes that in view of the rapid development of the LED industry, some relevant standards and norms can only catch up with the development of the LED industry, which is a deformed development to a certain extent, because the development is too fast and there is no corresponding standard, in order to continue to develop and blindly adopt European and American standards, the structural differences of ethnic signs between yellow and white people are ignored. In terms of LED lighting products, different races have different visual health requirements for color temperature, color rendering index, illuminance and other indicators. For researchers, we believe that LED quality standards should be developed, introduced and implemented on the basis of practical and in-depth experimental research, this standard should be based on a large number of scientific and objective experimental data, rather than simply translating and adopting relevant standards of European and American countries. This introduction and implementation is not only the performance specification of LED products, but also a kind of control over consumers' health according to different human body characteristics. He suggested.
