White laser light source capable of being homogenized

Abstract

The invention relates to a homogenizable white laser light source, and relates to the technical field of laser light sources. By arranging the laser emitting unit, the blue light emitting unit and the yellow light emitting unit, blue light laser and yellow light laser are generated. The first focusing lens mixes the blue laser and the yellow laser to generate Gaussian white laser. By arranging the plug-in dodging assembly, the plug-in dodging assembly can move to the first position or the second position. When the plug-in dodging assembly is located at the first position, the Gaussian white laser is homogenized, and uniform white laser is output to serve as a pattern lamp. When the plug-in dodging assembly is located at the second position, Gaussian white laser is directly output to serve as a searchlight. According to the invention, the plug-in dodging assembly is arranged, so that the generated white laser light source can be switched between a Gaussian beam and a uniform beam, and therefore, the light source can be used as a long-distance searchlight and can also be used as a pattern lamp.

Description

technical field [0001] The invention relates to the technical field of laser light sources, in particular to a homogenizable white light laser light source. Background technique [0002] The white laser light source is a laser light source based on the excitation of fluorescent materials by blue light to generate yellow laser light, and then the yellow and blue light are mixed to produce white light effect. This white laser light source is widely used in the fields of car lights, flashlights, searchlights and stage lighting. [0003] At present, the white laser light sources on the market generally only have Gaussian output with concentrated energy, and are used as long-distance searchlights. Since such high center energy is not conducive to the uniform pattern, it is not suitable for pattern lights; or it can only output uniformly, energy It is evenly distributed and used as a pattern light. Since this kind of energy is evenly distributed, it is not conducive to long-dista...

Problems solved by technology

[0003]The current white laser light sources on the market generally only have Gaussian output, and the energy is concentrated. They are used as long-distance searchlights. Because the high center energy of this type is not conducive to uniform patterns , so it is not suitable for pattern lights; or it can only output uniformly, and the energy is evenly distributed, and it can be used as pattern lights. Because this kind of energy is evenly distributed, it is not conducive to long-distance transmission, so it is not suitable for searchlights
