Abstract

The invention discloses a laser projection light path residual light energy conversion method, which is applied to the technical field of laser display, and comprises a light path shell of laser projection equipment, a light receiving reflector structure, a solar cell panel, a related control circuit and an electricity storage device. The laser projection system performs imaging by controlling the OFF light of the DMD, the OFF light of the DMD is directly irradiated on the shell of the optical assembly in the original design and is consumed in a shell heat dissipation mode, so that energy waste is caused, and meanwhile, a very high requirement is provided for heat dissipation of the system. According to the device and the method provided by the invention, the OFF laser of the DMD chip is collected to the solar cell panel through the light receiving reflector structure to convert energy. And through hardware circuit and software design, reasonable and effective utilization of the part of energy of the system after conversion is realized, and the heat dissipation burden of the system is greatly reduced.

Description

Technical field[0001]The present invention belongs to the field of laser display technology, and in particular, it is a laser projection optical path remaining light energy conversion and utilization method.Background technique[0002]Laser display technology has a high-color domain and high brightness as a new generation of display technologies. At the same time, the large screen is supported, but in order to improve the display effect, increase the power of the laser, the power is increasing, resulting in more optical paths in the OFF field of the DMD. The portion of the laser is continuously reflected in the optical path, gradually manifested in the form of heat, since the laser is carried with a large amount of capacity, so that the part is huge. The heat is constantly accumulated inside the equipment. If the heat sink is not perfect, it will seriously affect the normal operation of the equipment. In order to solve this problem, the heat dissipation effect is generally accelerated...
