LED Lighting Industry Will Produce What Kind of Pattern Change?

LED lighting

As a light source for illuminating the material basis of traditional light LED light source will be the mainstream , this is not to say that 10 years ago the basic , but very few people do not believe now estimate the . As the influence of the surface of mainstream LED light source is the impact on the industry , but also for the development of large lighting disciplines .

Since before the LED, the light source is a major source of thermal radiation , low pressure discharge light source and high intensity discharge light source , and the main purpose of which is the visual light illumination ( To be consistent with the existing version , this paragraph will be referred to the visual illumination lighting ) . These light sources , such as scales due to the flexibility , spectral and time and space , creating a center of gravity lighting disciplines is the material basis lighting " light " in the light of the study , after mature , there will be no big lighting basic disciplines of development. We see that the lighting disciplines in first half of the 20th century, there are a lot of research , but in the CIE1931, CIE1964 and CIE1976 chromaticity system , the last time in 1974 after the great progress that CRI finalized, lighting no major progress in basic subjects even fast approaching , " lighting " of the. This is mainly the material basis illumination is too inflexible , and in other words , it is that several sources , their application can be thoroughly studied . Therefore , after major research is the development of a new light , and thermal radiation source as the main gas discharge light source after , the focus of research to find new luminescent material , or the second light emitting method . But LED illumination into the mainstream , will make a great change in this situation :

When the main indicators and price (1) LED device technology has not yet reached maturity, especially the green LED pending further technological progress. Thus , over time , the development of LED technology will continue to be an important part of our lighting disciplines. However, the current LED has been developed to be able to get the application in many fields. Therefore , the focus of the lighting disciplines will gradually return to the lighting , the light source of the application, but not the light itself.

(2) LED high degree of flexibility will create tremendous research opportunities for future lighting disciplines. Because , LED high degree of flexibility to create a wide application field of LED , and in a variety of applications , is the high flexibility of the LED there is an optimal choice of applications , it is an academic problem that research opportunities . A typical example is the fill light LED plant , the presence of the human eye due to the different wavelengths V (λ) values ​​are different like , plants are also different fill fill light efficiency of different wavelengths of light , ie there is a concept of a light formulation . The current study is still in its initial stages.
