Description

Three-primary-color laser light source system

Technical Field

Background

With the gradual development of optical projection and illumination technologies, the projection devices on the market at present mainly include bulb projection and laser projection, and the main difference between the two projection devices is the light source for output, the bulb projection device uses a high-pressure mercury lamp as a light source, and the laser projection device uses laser as a light source. Laser projection devices employing laser sources have gradually gained traditional bulb projection devices due to the longer life of the laser sources and the superior color rendition compared to bulb sources.

The adoption of the step mirror light source array needs to occupy larger space, so that the volume of the equipment is increased, and the light path output by the step mirror light source array is scattered and low in concentration, so that the brightness of the output laser light source is obviously flat and low.

The X-mirror light source array integrates a plurality of reflecting mirror plates into an X-mirror structure similar to an X shape, the three-primary-color lasers are arranged around the periphery of the X-mirror structure, and the laser light sources input from the periphery are uniformly reflected to a specified direction through the X-mirror structure to be output. Although the occupied space and the volume of the equipment can be effectively reduced by adopting the X-mirror light source array, the integration level is low because the light path for reflecting and outputting by the X-mirror structure is complex; moreover, the lasers can only be arranged around the periphery of the X-mirror structure, so that the size and the number of the lasers are limited, the expandability is low, and the brightness of the output light source is insufficient.
