Description
The application is based on Application No. 201410284185.3, entitled light-source system and projector equipment, application
Day is the divisional application of 2014-06-23 patent application.
Technical field
The present invention relates to optical technical field, more specifically to light-source system and projector equipment.
Background technology
At present, solid state light emitter due to its long lifespan, it is environmentally friendly the features such as, it is aobvious in general illumination, special lighting and projection
It is widely used in showing.Wherein, white solid state light source is even more to have huge development potentiality in lighting field.
Prior art provides a kind of white light source that super brightness is realized using LASER Excited Fluorescence powder, the white light
Light source excites YAG using the bluish violet color laser of 440nm-455nm wavelength：The yellow fluorescent powder of Ce materials, generate efficient Huang
Color fluorescence, then the blue laser complementary with yellow fluorescence is formed using blue laser of the wavelength in 440nm-470nm, yellow is glimmering
White light source is formed after light and blue laser closing light.

One or more optical modulation device, such as DMD are incided respectively, on LCD chip, or LCOS chip.By optical modulation device
Three kinds of primary lights of RGB after modulation are spectrally put together to be output on screen by a projection lens again to be formed
Coloured image.Because the efficiency comparison of bluish violet color laser is high, heat endurance and long-term reliability are good.YAG：The fluorescence of Ce materials
The luminous quantum efficiency of powder is high, and heat endurance is good, so bluish violet color laser and YAG：Ce fluorescent material has combined to form one
The white light source of high efficiency, high reliability, and high brightness.
However, YAG is being excited using bluish violet color laser：The fluorescent material of Ce materials is formed in the white light source of white light, due to
YYAG：The yellow spectrum intensity of the fluorescent material stimulated emission of Ce materials is to weaken in red color segment, so that this kind of white light light
There is white balance in source, i.e. white light equalization point deviates Planck blackbody curve, a kind of partially green white is presented.
In order to avoid white balance problem, prior art provides green color components superfluous in a kind of white light for filtering synthesis,
So that white balance point is returned on Planck blackbody curve, to solve the problems, such as white balance.But this method is due to having filtered green glow
Composition, so as to reduce the light extraction efficiency of the white light source.
