Abstract

The invention discloses an optical-fiber fluorescent-wheel hybrid laser projector. The projector comprises a conductive optical fiber, a focusing lens, a total-reflection mirror and a hybrid fluorescent wheel. The conductive optical fiber comprises two portions, one portion is used to guide a laser to a light outlet, and the other portion is used to guide the laser to the hybrid fluorescent wheel.The focusing lens is used for focusing fluorescence emitted by the hybrid fluorescent wheel. The total-reflection mirror reflects all the focused fluorescence to the light outlet. An incident angle of the laser guided to the hybrid fluorescent wheel and a fluorescent surface of the hybrid fluorescent wheel is less than 90 degrees. In the invention, by using an optical-fiber fluorescent-wheel hybrid mode, a blue laser is directly coupled to a laser device so that propagation in the optical fiber is performed and a dust influence during a propagation process is avoided; and the optical fiber possesses good and stable light guide performance and attenuation of a light beam during the propagation process is greatly reduced.

Description

technical field [0001] The invention belongs to the field of projectors, and in particular relates to an optical fiber fluorescent wheel hybrid laser projector and a control method thereof. Background technique [0002] According to different light sources, projectors are mainly divided into three types: bulb, LED and laser. Among them, laser projectors are the most advanced projection technology at present, and laser projectors with fluorescent wheels are the most cost-effective models. The traditional fluorescent wheel laser projector uses multiple lenses to collimate and focus the laser light emitted from the blue laser, and then transmit it to the fluorescent wheel. This process requires multiple coated lenses, the attenuation of the lens itself and due to Dust entering the optical machine due to incomplete sealing will cause attenuation of the transmitted laser light. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
