Polarized light lighting device |
摘要 |
<p>A device for illuminating an area includes a circular reflector for focussing a light ray from a light source into a beam. A polarizer splits the beam into an effective beam having a first polarization direction and a complimentary beam having a second polarization direction. The polarizer reflects the effective radiation toward the area to be illuminated and transmits the complementary radiation to a rough surface having a roughness at least an order of magnitude greater than the wavelength of the light to diffuse the light and reflect at least a portion of the complementary beam back to the reflector and another portion to the area to be illuminated.</p> |
