The high degree of flexibility of LED will bring great opportunities for the lighting industry

Because before LED, the mainstream light source is the thermal radiation source, low pressure discharge light source with high intensity discharge light source, and the main purpose of the light source is the visual lighting (in accordance with the existing version of this paragraph, the following will be referred to as visual lighting lighting). Because of these light sources in scale, spectral and temporal space, the inflexibility created a focus subject is the material basis of "lighting illumination", in the light of mature, there is no basic lighting discipline big development.

As the material basis for the lighting of the light source, the traditional light source will not die, but will fade, perhaps in the near future, LED will be the main light source, this is 10 years ago does not say so, but now very few do not believe. The influence of LED as the main light source on the surface is the impact on the industry, but also for the development of lighting disciplines. Because before LED, the mainstream light source is the thermal radiation source, low pressure discharge light source with high intensity discharge light source, and the main purpose of the light source is the visual lighting (in accordance with the existing version of this paragraph, the following will be referred to as visual lighting lighting).

The high degree of flexibility of LED will bring great opportunities for the lighting industry

We see that there are many lighting discipline research results in the first half of twentieth Century, but in CIE1931, CIE1964 and CIE1976 color system, in 1974 after the last big progress is to determine the color index down, lighting discipline no big progress, even close to the "lighting project". This is mainly, the material base of the lighting is too flexible, in other words, is that a few light sources, their application research on it. Therefore, the main research is to develop a new light source, and as the main source of the gas discharge light source after the heat radiation, the focus of the study to find a new light-emitting material, or two light emitting method. However, the main source of LED lighting, will make this situation has changed a lot:

(1) the main indicators and prices of LED devices have not yet reached the technical maturity, especially green LED pending further technological progress.

Therefore, in a period of time, the development of LED technology will still be an important part of our lighting. However, at present, LED has been developed to be used in many fields. Therefore, the focus of lighting disciplines will gradually return to the lighting, that is, the application of light sources, but not the light itself.

(2) the high degree of flexibility of the LED will create a great opportunity for the future of lighting disciplines.

Because of high flexibility LED will create the broad application of LED, and in a variety of applications, and is the application of choice because of the flexibility of LED and there is an optimal, this is an academic problem, namely research opportunities. A typical example is the LED plant growth, and human existence because of different wavelength (lambda) V value of different plant growth are also similar, different wavelengths and different lighting efficiency, which is called as the formulation of the concept of light. The present study is still in its initial stage.
