Laser color mixing structure

Abstract

The invention discloses a laser color mixing structure, and the structure comprises a control system, a laser light source, a motor and a color wheel piece, wherein the laser light source and the motor are in electric control connection with the control system, and a motor is arranged to drive the color wheel piece to rotate; the color wheel piece is provided with a plurality of color areas, and the color areas are arranged around the rotation center axis of the color wheel piece in a circular array mode; the plurality of color regions at least comprise all basic colors of any color mixing mode; the light-emitting direction of the laser light source is aligned with the color area. Mixed color light is projected. Meanwhile, the percentage of each basic color in the mixed color light can besmoothly adjusted by controlling the irradiation time of the laser light source and the rotating speed of the motor, so that an electrodeless color mixing function is achieved, and the mixed color light with a wider color gamut can be projected.

Description

technical field [0001] The invention relates to a laser color mixing structure. Background technique [0002] The color mixing working principle of traditional DLP projectors is to use a combination of color separation filters such as red, green, blue, and white, which can separate the transmitted white light, and separate different monochromatic lights through the color wheel sequence. A full-color image is projected through the DMD and its projection lens. When the red light hits the DMD, the lens is tilted and flipped according to the position and intensity of the red information, and the green and blue light and video signals also work according to this principle. The image formed on the surface of the DMD can be projected through the projection lens. The working principle of color mixing of traditional DLP projectors is to project each single basic monochromatic light separately, and then each basic monochromatic light is superimposed and mixed on the screen. It can b...

Problems solved by technology

The working principle of color mixing of traditional DLP projectors is to project each single basic monochromatic light separately, and then superimpose and mix colors on the screen by each basic monochromatic light. It can be seen that the DMD module is an indispensable core of traditional DLP projectors. Components, the DMD module has the disadvantage of complex structure, so the traditional DLP projector has the disadvantage of complex structure, in addition, the traditional DLP projector also has the disadvantage of too narrow color gamut for color mixing
