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.
