Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the present invention includes a light source housing 1 , and a refracting mirror 2 is arranged inside the light source housing 1 . The refractor 2 is made up of a quadrangular prism 21 and two triangular prisms 22, 23. The cross section of the quadrangular prism 21 is a parallelogram, and the cross section of the triangular prism 22, 23 is an isosceles right triangle. The quadrangular prism 21 is located between the two triangular prisms 22, 23, and the oblique surfaces of the triangular prisms 22, 23 are attached to the opposite inclined surfaces of the quadrangular prism 21, so the cross section of the refracting mirror 2 is rectangular. Wherein, the vertical right-angled surface of the triangular prism 22 is used as the incident surface a of the refractor 2 , and the vertical right-angled surface of the triangula...

Abstract

The invention relates to a laser light source module, which is characterized by comprising a light source shell. A refractor the cross section of which is oblong is arranged in the light source shell; the refractor comprises a quadrangular prism the cross section of which is a parallelogram and two triangular prisms the cross sections of which are isosceles right triangles, wherein the vertical tight-angle surface of one triangular prism serves as an incidence surface, and the vertical tight-angle surface of the other triangular prism serves as an emergence surface; the outer side of the refractor is provided with a red light laser device over against the incidence surface and is provided with a light beam hole over against the light source shell of the emergence surface; a collimator is arranged between the emergence surface and the light beam hole; a green light laser device and a blue light laser device are arranged below the refractor, wherein light generated by the green light laser device can be totally incident upon a contact inclined surface near the incidence surface, and light generated by the blue light laser device can be totally incident upon a contact inclined surface near the emergence surface; and the other side of the refractor is provided with a three-colour laser photoreceptor opposite to the blue light laser device.

Description

technical field [0001] The invention relates to a light source module, in particular to a laser light source module. Background technique [0002] At present, semiconductor technology has become increasingly mature, and LED (Light Emitting Diode, Light Emitting Diode) lighting lamps are the most widely used. As an emerging technology in the field of semiconductor technology, laser technology has developed rapidly, and because of its wide range of laser output power, from hundreds of watts to several milliwatts, it has been widely used in many fields such as machinery, medical treatment and measurement. In terms of projection, LED is firstly used as a projection light source, which can produce vivid pictures through different projection methods. However, with the improvement of people's requirements for image quality, LED light sources can no longer meet the requirements of vivid colors. Therefore, laser light sources have gradually attracted people's attention. Moreover, c...
