Abstract

The invention discloses a laser light source and a laser projection device, relates to the technical field of projection devices, and is used for solving the problem of poor heat dissipation effect of a fluorescent wheel of laser projection equipment in the prior art. The laser light source comprises a laser used for providing an illumination light beam; a mounting cavity is formed in the mounting shell, and a light inlet communicated with the mounting cavity is formed in the mounting shell; the fluorescent wheel is arranged in the mounting cavity, and an illumination light beam emitted by the laser is incident to the wheel surface of the fluorescent wheel through the light inlet; the first heat dissipation device is arranged outside the mounting shell and is used for exchanging heat with the mounting shell in a heat conduction manner; and the second heat dissipation device communicates with the mounting cavity of the mounting shell and is used for guiding air to the wheel surface of the fluorescent wheel for heat dissipation. The laser light source is used for emitting light beams.

Description

technical field [0001] The present application relates to the technical field of projection devices, and in particular, to a laser light source and a laser projection device. Background technique [0002] Laser projection display technology is an optical display technology that uses a semiconductor laser to convert electrical energy into light energy, and projects the laser onto the screen by an optical path system, a circuit system, and a lens system. The optical path system of the laser projection device includes a fluorescent wheel. The fluorescent wheel is one of the key components in the optical path system. The high-speed rotating fluorescent wheel can separate part of the blue laser light source into red and green light sources, and finally pass through the DMD in the optical machine. The chip, and the lens, output the red, green and blue three primary color images to the projection screen. [0003] The fluorescent wheel in the existing laser projection equipment is ...
