Background technology
On current projection display apparatus, projected mostly using laser projection or Led.Using Led as projected light
Source, but Led is low as projection light source brightness, it tends to be difficult to meet user's request.And the scheme of laser projection is substantially and adopted
Reach the white light of projection needs with blue laser excitated fluorescent powder wheel, the scheme of blue laser excitated fluorescent powder wheel is adopted due to powder wheel
Rotated and realized with motor, belonged to mechanical movement, be also easy to produce mechanical displacement and noise, cause subsequent optical path difficult design.While by
Radiated in fluorescent material wheel difficult, fluorescence conversion efficiency is low, and efficiency is poor.
Therefore it is badly in need of noise and mechanical displacement caused by a kind of fluorescent wheel rotation for evading existing fluorescent material wheel scheme
Produced optical design deviation, heat dissipation characteristics are good, significantly improve the utilization solid state fluorescence of fluorescence conversion efficiency and projection brightness
Laser projection device.
Utility model content
In view of problem above, the utility model provides a kind of fluorescent wheel for evading existing fluorescent material wheel scheme and rotates institute
Optical design deviation produced by caused noise and mechanical displacement, heat dissipation characteristics are good, significantly improve fluorescence conversion efficiency and
The laser projection device using solid state fluorescence of projection brightness.In order to realize above-mentioned purpose of utility model, the utility model provides
Following technical scheme：
In the utility model, a kind of laser projection device using solid state fluorescence, including optical projection system, laser module, dissipate
Thermal modules and heat-conducting substrate, in addition to solid state fluorescence, the solid state fluorescence, which is directly smeared, to be fixed on radiating module or by leading
Hot substrate is fixed on radiating module, the integrated design of solid state fluorescence and radiating module, fluorescent material is had good radiating
Performance.The heat-conducting substrate is located at the top of radiating module, and on solid state fluorescence, the laser module is set the optical projection system
In the side of optical projection system.
The heat-conducting substrate is bolted on the top of radiating module.
The solid state fluorescence receives the direct laser beaten thereon of laser module, excites the assorted spectrum required for projection,
This process make use of the specular removal property of laser.The assorted spectrum of the solid state fluorescence can separate.So as to form high colour saturation
Degree.
Bank type light sources can be used in the laser module.
The laser module includes at least 2 laser lamps using each bank of LASER Light Source.
Single integrated-type light source can be used in the laser module.
