Modern lighting electric light sources are classified into incandescent lamps, fluorescent lamps, LEDs and the like according to the light emitting principle, and various light sources have advantages and disadvantages, but have great differences from natural light (sunlight) in spectrum, color temperature, color rendering index and the like. The incandescent lamp has a continuous spectrum, the color rendering index is closest to natural light, but the luminous efficiency is poor, the illumination is insufficient, and the dim feeling is brought to people. Although the spectra of the fluorescent lamp and the LED can form a continuous spectrum, the spectrum is a peak linear spectrum and is essentially different from the full spectrum of sunlight and incandescent lamps; however, the cost of implementation is high, and although the color rendering index of the light source can be closer to a full-spectrum light source such as natural light and an incandescent lamp, the difference still exists. The fluorescent lamp and the LED have the advantages of high lighting effect, good illumination and bright feeling.

Therefore, if different artificial electric light sources can be combined and matched, the advantages of the artificial electric light sources are fully exerted, and the artificial light sources with the spectrum, the color temperature, the color rendering index and the like similar to the natural light characteristics of the ground are manufactured, so that the artificial light sources are more in accordance with the physiology of eyes, the visual comfort is favorably ensured, and the artificial light sources are certainly beneficial to preventing myopia and maintaining the eye health.
The full spectrum is widely agreed by the public and scientists to maintain good visual quality in humans. At present, the technology of simulating full spectrum by using an LED light source technology is available, and different light sources are also used to form a lighting environment simulating natural light. The single light source technology is adopted to realize full spectrum, the cost is high, and the defect that the inherent short plate of the single light source is difficult to overcome exists. The technology of forming the environment similar to natural light illumination by integrating a plurality of light sources is complex in realization technology, high in cost and difficult to implement. If two or more kinds of light sources are combined and integrated under the integrated light source appliance, the implementation cost can be greatly reduced, and the light sources can be more conveniently installed and replaced. Secondly, various light source technology combinations are adopted, and all the wave bands (400-760 nm) of visible light in the solar spectrum are more favorably and really realized.
