    摘要: Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.

    摘要: A light source includes a light emitting unit including a light emitting layer for electrically emitting a light, and a waveguide for emitting a light irradiated from the light emitting unit into air through a light take-out surface formed on an end face, wherein an area of the light take-out surface of the waveguide is set to be smaller than that of the light emitting layer. Thus, the light irradiated from the light emitting layer is emitted through the light take-out surface of the waveguide. Therefore, it is possible to freely determine the size of the light source by the size of the light take-out surface of the waveguide. Consequently, it is possible to easily obtain a very small light source.

Each collimating element, which may be a compound parabolic concentrator or TIR lens, comprises an input side and an output side, is optically associated to one of the plurality of light source regions (57), and is configured to receive light emerging from the associated light source region (57) at its input side and to emit collimated light (29) from a respective collimated light emitting region (61) formed at its output side. In another embodiment the light emitting units are configured to emit primary light having a spectral distribution that compensates for spectral losses accumulated by the primary light while propagating within the light guide unit. In a further embodiment the collimated light has a direction that is tilted with respect to the normal to a light emitting face of the light source. In an additional embodiment the ration of the area of the plurality of light source regions with respect to the area of the main front face and/or the area of the non-source region is less than or equal to 20%.
