Abstract

The embodiment of the invention provides a light source assembly, which comprises a laser device used for emitting red, green and blue laser, a light combining component positioned between the laser device and a second lens group, the second lens group which is positioned between the light combining component and an angle adjusting component and is used for converging the light beams, and the angle adjusting component, wherein laser emitted by the laser device enters the second lens group after passing through the transmission area of the light combining assembly and enters the angle adjusting component after being converged by the second lens group, and the adjusted light beam enters the light combining assembly after being collimated by the second lens group and is reflected by the reflection area of the light combining assembly in the light emitting direction. According to the light source assembly provided by the invention, the problem of poor light spot consistency of the light beams emitted by the laser device is solved, the light homogenizing effect is further improved, and the image quality is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of projection technology, and in particular, to a light source component and a projection device. Background technique [0002] With the continuous development of science and technology, projection equipment is more and more used in people's work and life. At present, the projection equipment mainly includes a light source system, an optomechanical system and a lens. After the light beam is processed, it is emitted to the lens, so that the lens can emit the light beam to the projection screen, and then realize the display of the picture on the projection screen. In recent years, with the research and development of laser devices and the decline in cost, three-color lasers have gradually become the preferred device for projection light sources. [0003] When three-color lasers are applied to a light source system, the lasers of each color are usually arranged in a certain way. In the rela...
