Abstract
The invention discloses a full spectrum LED light mixing system, belongs to the technical field of LED light sources, and aims at solving the problem of poor continuity of a white light LED spectrum of the prior art. The full spectrum LED light mixing system comprises an LED lamp board, a reflector board is mounted on one side of the LED lamp board, and a diffusion board is mounted on the other side of the LED lamp board; the LED lamp board comprises a blue green lamp board body, a red light lamp board body and a white light lamp board body, the blue green light board body, the red light lampboard body and the white light lamp board body are sequentially arranged in the direction from the reflector board to the diffusion board, a first light guiding layer is arranged between the blue green light board body and the reflector board, a second light guiding layer is arranged between the red light lamp board body and the blue green light board body, and a third light guiding layer is arranged between the red light lamp board body and the white light lamp board body. The spectrum of the full spectrum LED illuminating system is close to a daylight spectrum, and the full spectrum LED light mixing system is good in light mixing effect, and high in spectrum continuity and color rendering performance.
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...
