    摘要： A light bulb includes light guides extending in a direction having a radial component with respect to a longitudinal axis, each light guide including a light input edge, opposed major surfaces, and light extracting elements at least one of the opposed major surfaces. In one embodiment, the light guides are disposed about an axial heat sink, and for each light guide, a respective light source is mounted to the axial heat sink to edge light the light guide such that light from the light source propagates in the light guide by total internal reflection. In another embodiment, a housing is at an end of the light guides, and for each light guide, a respective light source is mounted to the housing to edge light the light guide such that light from the light source propagates in the light guide by total internal reflection.

    摘要： A modular light-emitting panel assembly has first and second light guides edge lit by respective light sources. Each light guide has a light input edge, opposed side edges, opposed major surfaces and a pattern of light extracting elements at at least one of the major surfaces. The light guides are juxtaposed with a side edge of the first light guide abutting a side edge of the second light guide at a seam and with the major surfaces nominally coplanar. Various embodiments of the panel assembly additionally include respective structures that reduce visibility of the seam when the light sources illuminate the panel assembly.
