Abstract

See full text

A lighting assembly includes an assembly body. A first lighting unit is attached to the assembly body. The first lighting unit includes a number of light emitting diodes (LEDs) and optical elements arranged over the LEDs such that each optical element overlies only one associated LED. The first lighting unit is configured to illuminate a substantially rectangular region. A second lighting unit is attached to the assembly body and spaced from the first lighting unit. The second lighting unit includes a number of LEDs and optical elements arranged over the plurality of LEDs such that each optical element overlies only one associated LED. The lighting assembly is configured to direct the light toward the substantially rectangular area such that the light illuminates the substantially rectangular area with a uniformity across the substantially rectangular area that achieves at most a 3:1 ratio of the average illumination to the minimum illumination.
