Abstract: A lamp assembly (1800) may include a circuit board (201), one or more light-emitting devices (100) disposed on the circuit board (201), a heat sink (600) in thermal contact with a surface of the circuit board (201), a gasket (700) with a first surface in mechanical contact with the circuit board (201), a bezel (800) a surface (805) of which is in mechanical contact with a second surface of the gasket (700), and one or more fasteners (901) that may apply a force between the bezel (800) and the heat sink (600). A lamp array (2100) may include two or more lamp assemblies (1800), not all of which supply illumination with the same spectral characteristic, and a bearing mount (2000) that may support each lamp assembly (1800) and allow each to be oriented rotationally. A supply circuit (2500, 2600) may include a nonlinear resistive element (2501, 2601).

Abstract: A lamp assembly (500) may include a linear light-emitting array (100) and a reflecting surface (101) arranged to limit the angular distribution of direct light while supplementing with reflected light the intensity of the direct light on a flat surface (102) of an object being illuminated. The reflecting surface (101) may be shaped to cause the distribution of the total illumination over the illuminated portion of the flat surface (102) to be uniform or to be linearly tapered or to have another desired profile. The reflecting surface (101) may be part of a heat-sinking reflector (300) that may include a mounting surface (302), a blind (303), oblong mounting holes (304) allowing rotational adjustment, heat sink mounting holes (305), and/or one or more exit holes (307), and that may have end pieces (400) attached to it.
