Embodiment
[0028] Embodiment: The blue laser light that B light is sent by semiconductor laser diode 1 passes through converging lens II2, and due to the particularity of laser light, the laser is linearly polarized light-P light, which passes through PBS wavelength reflector 18, and passes through converging lens III4 through high-speed The rotating reflective fluorescent color wheel 5 passes through the λ / 4 wavelength plate 19 and then returns to the λ / 4 wavelength plate 19 through the total reflection mirror 20. At this time, the P light is converted into linearly polarized light-S light, which is reflected by high-speed rotation Type fluorescent color wheel 5 passes through converging lens III4 again, through the reflection of PBS wavelength selective reflector 18, then passes through converging lens I12, enters uniform light rod 13, enters TIR prism 15 through relay lens 14 after uniform light, after TIR The light is irradiated onto the display original 16, and the light reflected by...
