  • Patent number: 5988842
    Abstract: This invention is concerned with lightpipes and lightpipe arrays designed to redirect light from a mounted light source, such as a light-emitting diode (LED), or from an array of mounted light sources. The lightpipe and lightpipe array are advantageously designed to be mounted to a surface not directly in contact with the light source(s) or the surface on which the light source(s) is (are) attached and to redirect light such that light exits the lightpipe at an elevation between the elevation of the light-emitting end of the light source and the elevation of the surface mounting such light source after a plurality of light reflections within a lightpipe(s). Several methods for attachment of the lightpipes to a mounting panel are described. A preferred embodiment of the invention features attachment of the lightpipe or lightpipe array to a mounting panel using a bezel or bezels which substantially prevent interference from stray light sources and prevent light from mixing between lightpipes of an array.
