When the 3rd wavelength light beam 231 is incident upon the first fluorescent material 263 on the first plate body 26, can acts on the first fluorescent material 263 and convert the 4th wavelength light beam 233 to.Because the first fluorescent material 263 is a green emitting phosphor, the 4th wavelength light beam 233 that the 3rd wavelength light beam 231 produces after exciting the first fluorescent material 263 is green beam.4th wavelength light beam 233 reflexes to the first band-block filter 27, first band-block filter 27 along the 4th light path 204 and reflects the 4th wavelength light beam 233 again, makes the 4th wavelength light beam 233 enter equal optical element 25.
From the above, the light beam entering equal optical element 25 will have first wave length light beam 211 (blue light beam), second wave length light beam 221 (red beam) and the 4th wavelength light beam 233 (green beam).First wave length light beam 211 and second wave length light beam 221 are all provided by light emitting diode, therefore brightness is enough.And the 4th wavelength light beam 233 produced by the first fluorescent material 263, therefore brightness is also enough.In other words, the brightness of each color beam that equal optical element 25 exports is all sufficient, and the brightness that the image that therefore last projection arrangement projects does not have particular color (such as green) is on the low side.
Being more than the explanation of the light-source system of first embodiment of the invention, is then the explanation of the light-source system of other embodiment of the present invention.
Please refer to Fig. 6 and Fig. 8, Fig. 6 and two schematic diagram of light-source system that Figure 8 shows that second embodiment of the invention.The difference of the light-source system 2 ' of the second embodiment and the light-source system 2 of the first embodiment is, light-source system 2 ' more comprises one second plate body 28 and one second band-block filter 29, and the 3rd solid state light emitter 23 is another in order to provide one the 5th wavelength light beam 235.5th light path 205 of the 5th wavelength light beam 235 is different from the 3rd light path 203 of the 3rd wavelength light beam 231, and the 5th wavelength light beam 235 also can be a blue laser beams.
Before second plate body 28 compartment of terrain is arranged at the exiting surface closing optical element 24.Refer to Fig. 7 A, Fig. 7 A is depicted as the first plate body 26 of the light-source system of the second embodiment and the arrangement schematic diagram of the second plate body 28, second plate body 28 has a second surface 281 relative with exiting surface and one second fluorescent material 283, and the second fluorescent material 283 is arranged on second surface 281.
Refer to Fig. 7 B, Fig. 7 B is depicted as the first plate body 26 of the light-source system of the second embodiment of the present invention and the different composition aspect schematic diagram of the second plate body 28.First plate body 26 and the second plate body 28 can be combined into larger plate body 26 ', the first fluorescent material 263 of area and the second fluorescent material 283 is arranged on the surface 261 ' of plate body 26 ' respectively.
Referring again to Fig. 6 and Fig. 8, the 3rd wavelength light beam 231 can excite the first fluorescent material 263 being positioned at the first plate body 26, and produces one the 4th wavelength light beam 233; 5th wavelength light beam 235 can excite the second fluorescent material 283 being positioned at the second plate body 28, and produces one the 6th wavelength light beam 237.
In the second embodiment, the second fluorescent material 263 can be a red fluorescence powder, therefore the 6th wavelength light beam 237 is a red beam.In addition, second wave length light beam 221 and the 6th wavelength light beam 237 are the red beam of different-waveband, and the wave band of second wave length light beam 221 is positioned at the wave band of the 6th wavelength light beam 237.
Second band-block filter 29 is arranged between exiting surface and equal optical element 25.Now, the first band-block filter 27 can be arranged on exiting surface, and before the second band-block filter 29 can be arranged at the first band-block filter 27, and between the second band-block filter 29 and the first band-block filter 27, there is an angle.Second band-block filter 29 can pass through to the 5th wavelength light beam 235 with for first wave length light beam 211, and reflects the 6th wavelength light beam 237.
Then the light path that in light-source system 2 ', each light is advanced will be illustrated further.First light path 201 is identical with the light path of the conjunction optical element 24 of aforesaid first embodiment to the 4th light path 204, does not repeat them here.And the 5th wavelength light beam 235 (blue laser beams) of the 3rd solid state light emitter 23 enters conjunction optical element 24 through the 5th light path 205, after then being reflected by clearance layer 243, penetrate along the 5th light path 205 and close optical element 24.
5th wavelength light beam 235 of injection conjunction optical element 24 then injects the second fluorescent material 283 on the second plate body 28, to produce the 6th wavelength light beam 237 (red beam).6th wavelength light beam 237 then advances to the second band-block filter 29 along the 6th light path 206.
After 6th wavelength light beam 237 arrives the second band-block filter 29, the some light (light that namely wave band is identical with second wave length light beam 221) of the 6th wavelength light beam 237 can through the second band-block filter 29, and all the other light (namely the different light of wave band and second wave length light beam 221) can be reflected by the second band-block filter 29, then enter equal optical element 25.
