Abstract

The invention relates to the field of laser projection display and discloses a fluorescence color wheel device, a light source system and a laser projection device. The contradictions between the thickness of a buffing machine as well as the diameter of the fluorescence color wheel and the radiation are solved. The laser projection device disclosed by the invention comprises the buffing machine, a lens and a laser light source system, wherein the laser light source system comprises a laser device, a post-positioned lens set, a pre-positioned lens set, a dichroscope, a laser transferring and processing system, a light beam gathering component and the fluorescence color wheel device. The fluorescence color wheel device comprises a driving device and a color wheel, wherein the color wheel has a shape of a cylinder without a cover; the color wheel comprises a base and a side walls; openings are symmetrically and oppositely formed in the side wall; the side wall is divided into two sides by the openings; various fluorescent powders are coated on the outer side of the side wall on each side; the same fluorescent powders on the side walls on the two sides are in equal width and are symmetrically opposite to each other. The fluorescence color wheel device is suitable for the laser projection device.

Description

technical field [0001] The invention relates to the field of laser projection display, in particular to a fluorescent color wheel device, a light source system and laser projection equipment. Background technique [0002] At present, projection equipment is widely used in various application scenarios such as home, business, education, and advertisement. With the improvement of usage requirements, halogen lamps and LEDs as projection display light sources have a great shortage in terms of lifespan or brightness, and it is difficult to meet the increasingly high usage requirements. [0003] Laser Diode (Laser Diode) has the characteristics of high efficiency, high brightness, low power consumption, long life, etc., and is gradually widely used in projection display. According to the principle of chromaticity, red, green and blue light are generally used as the three primary colors in the field of projection. However, for laser diode LDs, red and green LDs, because of effici...
