Example Embodiment
[0037] Example one:
[0038] The light source device includes a phosphor wheel and also includes a phosphor excitation light source;
[0039] The phosphor wheel is coated with green phosphors with different emission spectra in sections. The excitation light from the phosphor excitation light source irradiates the rotating phosphor wheel, and the phosphor on the phosphor wheel emits light of corresponding wavelength in turn . Specifically, the phosphor wheel is coated with yellow-green corresponding emission spectrum phosphors and dark green corresponding emission spectrum phosphors in sections.
Example
[0040] example 1:
[0041] Such as Figure 1a As shown, the excitation light emitted by the phosphor excitation light source 101 passes through the refractive lens group and the reflective lens group 102 to form a parallel beam of excitation light. The parallel beam of excitation light passes through the transmission of the first group of lenses 103 and the first dichroic in turn. After the transmission of the mirror 104 and the transmission of the second set of lenses 105, it is irradiated on the phosphor wheel 106, so that the phosphor coated on the phosphor wheel 106 emits light of corresponding wavelength, and the light emitted by the phosphor sequentially passes through the second The transmission of the group lens 105 and the reflection of the first dichroic mirror 104 reach the reflective surface of the second dichroic mirror 107;
[0042] The red light emitted by the red light source 108 reaches the transmission surface of the second dichroic mirror 107; the blue light emitt...
Example
[0044] Example 2:
[0045] Such as Figure 1b As shown, the excitation light emitted by the phosphor excitation light source 120 forms a parallel beam of excitation light after passing through the refractive lens group and the reflective lens group 121, and the parallel beam of excitation light passes through the transmission of the first group of lenses 122 and the first dichroic in turn. After the transmission of the mirror 123 and the transmission of the second set of lenses 124, it is irradiated on the phosphor wheel 125, so that the phosphor coated on the phosphor wheel 125 emits light of the corresponding wavelength, and the light emitted by the phosphor sequentially passes through the second The transmission of the group lens 124 and the reflection of the first dichroic mirror 123 reach the X prism 126;
[0046] The red light emitted by the red light source 127 reaches the X prism 126; the blue light emitted by the blue light source 128 reaches the X prism 126; the X prism 1...
