Abstract

The invention discloses a projection light source and projection equipment, and belongs to the technical field of photoelectricity. A light combination lens in the projection light source comprises a reflection area and two transmission areas located on the two sides of the reflection area respectively; a fluorescent wheel comprises a first area and a second area, and a light diffusion part is arranged on the second area; a laser is used for emitting multiple laser beams, and the multiple laser beams are emitted to the two transmission areas of the light combination lens, so that the laser beams are transmitted to a convergent lens; the convergent lens converges the laser to the fluorescent wheel; the fluorescent wheel is configured to rotate around a rotating shaft, and different areas in the fluorescent wheel are irradiated by the converged laser in the rotating process of the fluorescent wheel; the first area is excited to emit laser, and fluorescent light passes through the convergent lens and is emitted to the reflection area; the light diffusion part of the second area diffuses the converged laser, and the diffused laser passes through the convergent lens and is emitted to the reflection area; and the reflection area reflects incident light in a target direction. The problem that the projection light source is large in size is solved. The projection light source is used for emitting light.

Description

technical field [0001] The present application relates to the field of optoelectronic technology, in particular to a projection light source and projection equipment. Background technique [0002] With the development of optoelectronic technology, the requirements for miniaturization of projection light sources in projection equipment are getting higher and higher. [0003] related technologies, such as figure 1 As shown, the projection light source includes: a laser 001, a dichroic mirror 002, a first collimating lens group 003, a fluorescent wheel 004, a light guide 005 and a relay circuit system, and the relay circuit system includes a second collimating lens group 006 , the first reflective mirror 007, the first collimating lens 008, the second reflective mirror 009, the second collimating lens 010, the third reflective mirror 011 and the third collimating lens 012. The dichroic mirror 002 and the fluorescent wheel 004 are sequentially arranged on the light emitting si...
