Description
Technical field
The present invention relates to Color Laser Projection Technology, particularly to the technology of LASER Light Source illumination.
Background technology
In laser projection display field, mainly there are two kinds of LASER Light Source lighting engineering.
One is: uses redgreenblue laser instrument as illuminator, is drawn by light path system after trichroism sharp actinic light
Lead and be illuminated on process chip, and export colour pitcture by projection imaging mode.But use the projection of this technology
There is serious laser speckle problem in system, and cost is high, it is impossible to carries out mass market popularization and application.
Another kind is: be provided with the laser instrument sending single blue wave band on light supply apparatus, optical system mobile phone swash
Light beam also focuses on, and gets on fluorescent powder color wheel surface approximating the form of point source, and fluorescent powder color wheel surface-coated has all kinds of glimmering
Light powder realizes wavelength convert, and can obtain in back-end optical system according to the rotation of fluorescent powder color wheel has the RGB three of sequential
Plant color.In this technical scheme, generally blue light is designed by hollow out or the transparent section of fluorescent powder color wheel, by solely
Vertical blue light paths is transmitted, and red-green glow then occurs on fluorescent powder color wheel surface to launch and be collected, final RGB three
Kind color of light completes to close light on dichroic eyeglass and exports and be directed on the imager chip of rear end, and its light path schematic diagram sees figure
1, it includes laser light source module 1, dichroic eyeglass 2, Quasi-straight light-focusing battery of lens 3, phosphor color conversion equipment 4 (fluorescent material
Colour wheel, has following reflection substrate) and blue light paths 5, in figure, the blue light of laser light source module 1 output is through dichroic eyeglass
2 reflect and carry out shaping into Quasi-straight light-focusing battery of lens 3, make output blue light be incident on phosphor color with the form of approximation point source and turn
On changing device 4, the reflection substrate of phosphor color conversion equipment 4 is made up of segmentation structure, is predominantly coated with on its reflection substrate
The section being covered with red fluorescence powder, the section being coated with green emitting phosphor and hollow out (or transparent) section (make the district that blue light passes through
Section), the section being coated with red fluorescence powder and the section being coated with green emitting phosphor excite product when by above-mentioned blue light illumination
Raw HONGGUANG and green glow also pass back through Quasi-straight light-focusing battery of lens 3 relative to blue light incident before and export collimated beam and enter two
To color eyeglass 2, hollow out (or transparent) section is then blue light penetration phosphors color conversion apparatus 4 position entering blue light paths 5
Put, blue light enter after blue light paths 5 by a series of reflections and lens and/or battery of lens finally export collimated beam entrance two to
Export after color eyeglass 2 and HONGGUANG and green actinic light, it is seen then that in this scenario, blue light and red-green glow need two-way light to be implemented separately,
Its system design difficulty is relatively big, and technological process is more complicated, also can bring when producing in rear end such as assembling and setting difficulty relatively greatly and
