照明器
Document Type and Number:
Japanese Patent JP6877363
Kind Code:
B2
Abstract:
An optical device is disclosed for generating illumination that appears to emanate from a location different from the actual light source. The device includes a waveguide having opposed first and second planar faces. A light source is positioned to direct light into the waveguide. A diffractive optical element (DOE) is formed across the waveguide. The DOE distributes the light entering the waveguide via total internal reflection and couples the light out of the surface of said first face.
