Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0031] With the development of optoelectronic technology, the requirements for the display effect of the projection screen of the projection device are getting higher and higher. In related technologies, the positions of the light spots formed by the blue light emitted by the light source module are quite different from those formed by the red light and green light, and the coincidence degree of the light spots formed by lights of different colors is low, resulting in the color of the light spots formed by the light emitted by the light source module being different. The uniformity is low, which in turn leads to poor display effect of the projected picture formed by the light emitted by the light source component. And, please con...

Abstract

The invention discloses a light source assembly and projection equipment, and belongs to the technical field of photoelectricity. A light-emitting assembly in the light source assembly emits laser, and the laser penetrates through a collimating lens group from one side of an optical axis in the collimating lens group and is emitted to a fluorescent wheel; the fluorescent wheel is configured to rotate around a rotating shaft, so that in the rotating process of the fluorescent wheel, the laser is emitted to different areas in the light emitting surface of the fluorescent wheel; when the laser is emitted to the first area, the laser excites the first area to emit fluorescent light, and the fluorescent light passes through the collimating lens group and is emitted to the reflecting part; when the laser is emitted to the second area, the laser is reflected in the second area and then penetrates through the collimating lens group to be emitted to the reflecting part, the second area is intersected and not perpendicular to the optical axis of the collimating lens group, and the second area faces one side of the optical axis in the collimating lens group; and the reflecting part is used for turning the transmission direction of the incident light. The problem that the display effect of a projection picture is poor is solved. The light source assembly is used for emitting light.

Description

technical field [0001] The present application relates to the field of optoelectronic technology, in particular to a light source assembly and projection equipment. Background technique [0002] In the projection device, the light emitted by the light source assembly can be used for image projection after being collected by the light receiving component. [0003] Such as figure 1 As shown, the light source assembly in the related art includes: a laser 001 , a dichroic mirror 002 , a fluorescent wheel 003 , a converging lens 004 , a collimating lens group 005 , a light receiving component 006 and a reflector 007 . Laser 001, mirror 007, dichroic mirror 002, collimating mirror group 005 and fluorescent wheel 003 are arranged in sequence along the first direction (y direction in the figure), and mirror 007 covers the dichroic mirror 002 In the first area, the reflecting mirror 007, the dichroic mirror 002, the converging lens 004 and the light-receiving component 006 are sequ...
