In other embodiment, colour wheel can also be arranged to reflection or part the first output light sequence of reflection and the second output light sequence.
Fig. 8 is referred to, Fig. 8 is the structural representation of the 3rd embodiment of the light-source system of the present invention.As shown in figure 8, this
The light-source system 80 of embodiment mainly includes light source 81, beam condensing unit 82, colour wheel 83, drive device 84 and switching device 85.
Colour wheel 83 includes being provided with the first area of at least two first color sections and is provided with the secondth area of at least two second color sections
Domain, such as the first area shown in Fig. 4-6 and second area, and then the first different output lights is produced under different working modes
Sequence and the second output light sequence.
The difference of light-source system 30 shown in light-source system 80 and Fig. 3 of the present embodiment is, the first of colour wheel 83
Part the first color section in region is arranged to transmit a part of output light in the first output light sequence, and another part color section is set
Another part output light into the first output light sequence of reflection.Now, another portion of a part of output light of transmission and reflection
Point output light merges device through being divided the light path that optical filter 86 and 89 and speculum 87 and 88 are formed and carries out light path merging.Example
Such as, when colour wheel 83 is using colour wheel structure shown in Fig. 4, blue light exciting light caused by light source 81 through beam condensing unit 82 collect and in
It is transmitted to after through being divided optical filter 86 on colour wheel 83, the blue light color section transmission blue light exciting light in the first area of colour wheel 83,
And blue light excitation wavelength is converted into feux rouges and green glow and reflected by red light color section and green light color section.The blue light of transmission excites
Light reflects through speculum 87 and 88, then is transmitted through being divided optical filter 89.The feux rouges and green glow of reflection reflect through being divided optical filter 86
Reflected again through being divided optical filter 89 afterwards, and then carry out light path with the blue light exciting light that light splitting optical filter 89 transmits and merge.Equally, originally
Part the second color section of the second area of the color section 83 of embodiment can also be arranged to transmit one in the second output light sequence
