Abstract

The invention relates to a projection laser combining device with the application of laser to a wide-band light model, and belongs to the technical field of laser display. The invention aims to solvethe technical problems of poor illumination quality, high cost and no elimination of speckle of an existing laser projection device. The technical scheme is that the device comprises a laser module, alens group, a wide-band incoherent light source module, a converging lens and a light homogenizing tube, the lens group is disposed in front of the light emitted by the laser module, the wide-band incoherent light source module is disposed in front of the lens group, the converging lens is disposed in front of the wide-band incoherent light source module, and the light homogenizing tube is disposed in front of the converging lens.

Description

technical field [0001] The invention relates to a projection laser beam combination device for lasers applied to broadband light models, and belongs to the technical field of laser display. Background technique [0002] As a new type of projection technology, laser projection uses a broadband incoherent light source or laser as a light source. The red, blue, and green lights are combined into white light by a beam combining device, and then transmitted to the projection screen after being integrated by a uniform light tube to complete the project. The whole laser projector shows the process. The main factors affecting the development of projection technology are the price of light source, luminous quality and luminous power of light source. [0003] The pure broadband incoherent light source device or laser array has poor beam quality of the output light source, and cannot satisfy the characteristics of low price and excellent luminous quality at the same time. [0004] As...
