| description | Disclosed is a lighting system (10) that illuminates a surface (16) with a uniform illumination pattern (12). The lighting system includes a plurality of lighting units (14) that each emit a light beam that has a variable vertical illumination distribution and a variable horizontal illumination distribution. The intensity of each light beam is uniform in a central region of the horizontal illumination distribution, and non-uniform at each end of the horizontal illumination distribution. Similarly, the intensity of each light beam is uniform in a central region of the vertical illumination distribution, and largely non-uniform at each end of the vertical illumination distribution. The light beams overlap in the region of horizontal nonuniformity in order to create an illumination pattern that appears uniform. |
