In recent years, the investment in LED lighting has become "hot" and can even be said to be frenetic. Due to the "ruthlessness" of many problems in the application, people's minds are forced to wake up, and the understanding of LED lighting returns to the rational track, forcing some people who are dizzy to start thinking calmly.
Through the "fanatic" phenomenon, we should seriously reflect our understanding of LED lighting to correct our way of thinking, strategic direction and scientific research methods.
However, at present, many people have two misunderstandings about LED light source, lighting and application.
One of the misunderstandings: the chip is equal to the light source
The electric light source has strict technical standards. There are strict requirements for many indicators such as contrast, lumens, color rendering, color temperature, power, light decay, harmonics, and life. This is the result of technological advancement of electric light source for more than 100 years. . A chip or a PN junction, although a generalized light source, is only a luminescent element in terms of a standard electric light source, and is by no means a standard electric light source. The manufacture of chips into various standard electric light sources is not a simple patchwork, but a scientific design and combination. It requires a large number of technological innovations in related fields such as materials and electronics, and requires a large number of scientific experiments. An electric light source that is not equal to the modern meaning and has strict standards.
However, many "experts" or "officials" have exchanged concepts in their speeches, confused common sense, did not talk about science, and blindly promoted them. Such experts or local government agencies promote LED lighting, or "do not understand" and "understand". Either "understand" and "do not understand" are all ulterior motives, the generosity of the country, and the interests of all parties.
Error two: a light source illuminating <br> <br> equal to the "light" will be able to illuminate right. Torches, candles, and oil lamps have been historical light sources, and they still play a role in lighting in some areas where electricity is not available. But in the 21st century, it seems that the original illumination is the illumination that is compatible with the social form and productivity level at that time. Today, if you use an LED chip compared with a torch or an oil lamp, you will be ridiculed. Some people will say that LED lighting is high-tech. But an indisputable fact is that some people use the single light source - a PN junction as a light source, as the whole illumination, and do "self-floating themselves."
Due to the characteristics of the LED light source itself, such as the high directivity of the light, heat dissipation, driving and optical processing are required, which determines that the LED as a light source must be "the maturity of the whole system". In this sense, or from the point of view of modern lighting, the illuminating is not necessarily the "light", in terms of LED lighting, the single source is never equal to the illumination.
From a PN junction to a modern light source, to scientific lighting and green lighting that are compatible with the environment, there is a long way to go. This includes deep understanding of LED lighting, advances in materials and technology, equipment manufacturing and applications. The secondary development of products, especially the maturity of the system, the appropriate cost performance and large-scale production, can not do these points, the large-scale promotion and application is just a beautiful "vision" and embarrassing.
