Abstract

The invention provides a multicolor LED mixed-light illumination method and system, and the method comprises the steps: acquiring specification information parameters of LEDs of each color; obtaininga biological clock adjustment index and an optical color index parameter of the LEDs of each color according to the specification information parameter, and calculating the luminous intensity of eachcolor LED according to the specification information parameters, the biological clock adjustment indexes and the optical color index parameters, and driving the LEDs of each color so that the brightness values of the LEDs of the respective colors are consistent with the calculated luminous intensities of the LEDs of the respective colors; mixing the light of the LEDs of each color uniformly, and emitting the mixed light.. The multicolor LED mixed-light illumination method and system provided by the invention adopt a non-blue light emitting mechanism, and achieve the emission of white light bymixing a plurality of colored LEDs. Since the spectral range of the colored LEDs can be selected, the harmful blue light can be more completely eliminated.

Description

technical field [0001] The invention relates to a lighting device, in particular to a multi-color LED mixed light lighting method and a lighting system. Background technique [0002] The emergence and application of light-emitting diodes (LEDs) have brought about ten times the energy efficiency of traditional light sources. Ordinary white LEDs can produce about 100 lumens of luminous flux per watt of energy consumed, that is, the luminous efficacy is 100lm / W, which is much greater than that of incandescent and fluorescent lamps. This high-efficiency white LED is based on the blue light emission mechanism: the surface of the blue LED is covered with yellow phosphor, a part of the blue light excites the phosphor to produce yellow light, and the other part of the blue light directly passes through the phosphor to continue to emit blue light. The result is that blue light mixes with yellow light to produce white light. Therefore, the white LED spectrum inevitably contains a la...
