Embodiment 1

[0036] This embodiment is used to provide a homogenizable white laser light source, such as figure 1 shown, including:

[0037] (1) Laser emission unit, used to generate blue laser light;

[0038] Specifically, the laser emitting unit includes a blue laser 1 and a focusing assembly, a reflecting mirror 4 , a diffusing mirror 5 and a dichroic mirror 6 arranged in sequence along the transmission direction of the optical path. The blue laser 1 is used to generate a blue light beam. The focusing component is used for focusing the blue light beam to obtain the focused blue light beam. The reflecting lens 4 is used to horizontally reflect the focused blue light beam to obtain the reflected blue light beam. The diffusing lens 5 is used to homogenize the reflected blue light beam to generate blue laser light. The dichroic lens 6 is used to reflect a part of the blue laser light to enter the yellow light emitting unit, and transmit the remaining blue laser light to enter the blue l...

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...
