Abstract

The invention discloses a projection light source and projection equipment, and belongs to the technical field of photoelectricity. In the projection light source, a first laser and a second laser are sequentially arranged along a first direction, and a first light combining mirror and a second light combining mirror are sequentially arranged along the first direction; in the first laser and the second laser, the emergent area of the first laser and the emergent area of the second laser are parallel to the first direction; laser emitted by the first laser device is emitted to the first light combining mirror, and the first light combining mirror is used for reflecting the incident laser to the second light combining mirror in the first direction; the laser emitted by the second laser device is emitted to the second light combining mirror, and the second light combining mirror is used for reflecting the laser emitted by the second laser device in the first direction and transmitting the laser emitted by the first light combining mirror in the first direction. The problem that the display effect of the projection picture formed based on the laser emitted by the projection light source is poor is solved. The invention is used for emitting light.

Description

Projection light source and projection equipment 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, projection equipment is widely used, and the requirements for the display effect of the projection screen are also Higher and higher. [0003] The projection light source in the projection device can emit lasers of various colors, and then based on the laser projection to form a projection shadow screen. In the related art, the projection light source may include a laser and a light combining lens group, and the light combining lens group can emit the laser The lasers of different colors are mixed and emitted. The laser light can then be directed to the subsequent modulated optical path, based on the image to be projected The laser is modulated and then emitted, thereby reali...
