Abstract

The invention discloses an optical machine illumination system, and belongs to the field of laser projection. The optical machine illumination system comprises an illumination mirror group and a light valve. The illumination mirror group comprises a dodging assembly, a collimating lens group, a rectangular reflector and a total internal reflection prism, the collimating lens group comprises at least three lenses, and the at least three lenses are spherical lenses; and an included angle is formed between each of two adjacent sides of the rectangular reflector and the display surface of the light valve. According to the optical machine illumination system provided by the invention, the rectangular reflecting mirror is rotationally placed to avoid other structures in the light machine illumination system, the rectangular reflecting mirror is prevented from being cut, and the lenses are spherical lenses which are relatively easy to process, so that the problem that the manufacturing process of the light machine illumination system is relatively tedious in the related technology is solved; and the effect of simplifying the manufacturing process of the light machine lighting system is achieved, and meanwhile the manufacturing cost of the light machine lighting system is reduced.

Description

technical field [0001] The present application relates to the field of laser projection, in particular to an optical-mechanical lighting system and laser projection equipment. Background technique [0002] At present, laser projection technology is a new type of projection technology on the market. Laser projection technology has the characteristics of high picture contrast, clear imaging, bright colors and high brightness. These characteristics make laser projection technology become the mainstream development direction in the market. [0003] An optical-mechanical lighting system used in laser display projection equipment to provide the required light source for laser projection equipment. When the optical-mechanical lighting system is in use, it needs to use the reflector to deflect the light. In the actual installation process, because The installation space of the optomechanical lighting system is small. In order to avoid other structures in the optomechanical lighting ...
