    摘要： In one embodiment, a light-emitting apparatus includes a plurality of adjacent, overlapping light-guide plates formed of substantially transparent material, and a plurality of light sources. Each of the light-guide plates has i) first and second ends, ii) one or more substantially transparent surfaces through which light is emitted, and iii) one or more reflective surfaces to redirect light within the light-guide plate. Where first and second light-guide plates are adjacent, the first end of the first light-guide plate A) underhangs the second end of the second light-guide plate, and B) is positioned opposite a primary light-emitting side of the apparatus. The plurality of light sources are optically coupled to the first ends of the light-guide plates so as to illuminate the interiors of the light-guide plates.

    摘要： A light source having a flexible substrate and a plurality of dies having LEDs is disclosed. The light source can be conveniently utilized to provide an extended light source by bonding the light source to a suitable light pipe. The substrate is divided into first and second regions. The dies are bonded to the substrate in a first region. A portion of the surface of the substrate in the second region is reflective. The substrate is bent such that the second region forms a reflector that reflects light that would otherwise be emitted in a non-useful direction to a more useful direction. The substrate can be constructed from a three layer flexible circuit carrier in which the dies are mounted on a bottom metal layer to provide an improved thermal path for heat generated in the dies.
