Other 80% or so LD blue lights can carry out being converted into required blue light by material for transformation of wave length, adjust two parts blue light
Ratio can couple any required chromaticity coordinates point blue light.
Lens or lens group 7 can also be set on the light channel structure of polaroid 4 and optical-mechanical system 8, for the transmission that is stimulated
Light enters line convergence.Wherein, lens group includes multiple lens, and for that will be stimulated, transmitted light is coupled to optical-mechanical system to greatest extent
In 8, it is ensured that the brightness of complete machine.
If carrying out colour filter to blue stimulated light using the optical filter of blueness in optical-mechanical system 8, the wave band for the blue light that is stimulated to the greatest extent may be used
460-490nm can be concentrated on.
Because in Color Laser Projection Technology traditional at present, blue light paths are not excited through fluorescence wheel apparatus, but utilize another
The last light again with being excited by fluorescence wheel apparatus of an outer light path does closing light, blue light of such framework except laser in itself be partially purple,
Need closing light adjustment, system bulk heavy outer, can also be after laser projection to picture, picture has the effect of speckle.It is and of the invention
By changing the fluorescent wheel in existing light path into fluorescent wheel that blue light is excited mode, while by 45 degree of blu-ray reflections in existing light path
Mirror changes 45 degree of polariscopes into, realizes the mode that the light of RGBY colors is all excited using fluorescent material.Using excitated fluorescent powder
Blue light is produced, so as to efficiently solve the partially purple problem of blue light, can also allow each color to deactivate photochemical, speckle is not had on picture
Effect；Furthermore light path of the invention only needs single light path, except can with reduction system volume, reduce number of lenses and reduction
, can also be because the problem of reducing after simplified design on procedure for producing outside cost；In addition, in the part of white light closing light, because
It is single light path, therefore is not in the uneven phenomenon of white picture.
Description of the those skilled in the art in embodiment 1 understand that this technology for being excited to produce blue light can not only be used
In projection light-source system, can also be used in the light-source systems such as illumination；The light-source system can be used as projection light source system accordingly
