  • Illumination sources and systems
    Patent number: 6164789
    Abstract: The reflectivity of a substrate can be improved by combining a reflective diffuse layer with a specular layer. The light output of individual light sources can be improved by embedding them in a composite diffuse and specular substrate resulting in a superior illumination source. A tapered coupling waveguide having a large input surface can be used to couple the illumination source to a thin waveguide having a relatively small input surface area.
