Problems solved by technology

On the laser display, it is necessary to receive and display the image in real time, so the second method is usually used to suppress the speckle, and many methods have emerged, such as the rotating fiber method, the laser resonator method, the vibrating screen method, and the multi-fiber splitting method. beam method, ultrasonic grating speckle elimination method, etc., but the existing methods have problems such as single speckle elimination mechanism, poor speckle elimination effect, fuzzy screen display, complex device structure and high cost

Abstract

The invention discloses a long-service-life modular laser fluorescent light source system capable of improving shimming of a light source, which comprises a blue laser light source A (101), a scattering sheet A (102), a blue-reflecting and yellow-transmitting beam combiner (103), a lens group A (104), a fluorescent element (105), a lens group B (106), a scattering sheet B (107), a blue laser light source B (108), a lens group C (109), a red-green-reflecting and blue-transmitting beam combiner A (110), a lens (111), a scattering sheet C (112), a red-green-blue laser light source (113), a lens group D (114), a light flux tube (115), a red-green-reflecting and blue-transmitting beam combiner B (116), wherein the scattering sheet C (112) is arranged in the vibration mechanism. The system is reasonable in design, high in operation stability and wide in application range, and has very high generalization performance and very good practical application value.

Description

technical field [0001] The invention relates to the technical field of laser projection, in particular to a modularized laser fluorescent light source system with long service life and improved shimming of the light source. Background technique [0002] As the most advanced projection technology at present, laser projection has developed rapidly in recent years and has formed three main product forms: pure laser light source, laser fluorescent wheel and laser LED light source. Among them, laser projectors with phosphor powder are the most cost-effective machines. type. Laser fluorescence projection is irradiated on the fluorescent powder by blue light laser to produce yellow light, which is combined with another part of the blue light machine laser that transmits the optical path, which effectively reduces the coherence of the light source and can effectively eliminate speckle. However, high lumens or long-term laser irradiation on the fluorescent wheel will cause the local...
