Abstract
A full-spectrum LED light mixing system belongs to the technical field of LED light sources; the present application aims to improve the problem of poor spectral continuity of white light LEDs in the prior art. This application includes an LED light board, one side of the LED light board is equipped with a reflective plate, and the other side of the LED light board is equipped with a diffuser plate. The LED light board includes a blue-green light board, a red light board and a white light board. The blue-green light board, The red light panel and the white light panel are arranged sequentially from the reflector to the diffusion plate, the first light guide layer is arranged between the blue-green light panel and the reflector panel, and the second light guide layer is arranged between the red light panel and the blue-green light panel layer, a third light guide layer is arranged between the red light board and the white light board. The spectrum of the full-spectrum LED lighting system of the application is close to that of sunlight, with good light mixing effect, strong spectrum continuity and high color rendering.
Description
technical field [0001] A light mixing system belongs to the technical field of LED light sources, and in particular relates to a full-spectrum LED light mixing system. Background technique [0002] As a new type of cold light source, LED has the advantages of small light source unit area, good impact resistance, high luminous efficiency, long service life, wavelength can cover visible light, good monochromatic performance, narrow full width at half maximum, and non-coherent light emission. Light, can better control the composition of the luminescent spectrum and so on. At present, the mature technology of blue light exciting yellow phosphor to produce white light has greatly improved the light efficiency and color rendering of white LED, but there is still a big gap compared with sunlight. Therefore, simulating natural light based on LED synthetic spectrum has been widely studied, but there are still problems to be solved urgently in how to improve the light mixing efficien...
