摘要： A lighting assembly includes a light source to emit on-axis light rays at smaller angles relative to an optical axis of the light source, and off-axis light rays at larger angles relative to the optical axis and spectrally different from the on-axis light rays. The lighting assembly additionally includes a light guide having a light input edge adjacent the light source and opposed major surfaces between which light from the light source propagates by total internal reflection. The light input edge has an edge feature aligned with the light source to receive light therefrom. The edge feature specularly redirects the on-axis light rays and the off-axis light rays differently to increase overlap between the on-axis light rays and the off-axis light rays within the light guide. The increased overlap reduces spatial color variation of light extracted from the light guide between locations at different angles from the optical axis.

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.

摘要： A flashlight includes first and second solid-state light sources, a collimating optical element, and a light guide. Light output by the first light source interacts with the collimating optical element to output a light from the flashlight along an optical axis of the collimating optical element. The light guide includes an outer major surface, a first end, a second end, a longitudinal axis extending between the first end and the second end, and a light input edge at the first end. Light from the second light source is input to the light guide at the light input edge and propagates in the light guide by total internal reflection. The light guide additionally includes light extracting elements to extract light from the light guide with a radial component relative to the longitudinal axis and the optical axis.
