Abstract
A light bar for illuminating a surface that is substantially perpendicular to the light bar includes an elongated housing extending along an edge of the surface to be illuminated. The housing has a wall adjacent the surface to be illuminated, and at least portions of that wall are transparent. A series of light emitting diodes (LEDs) are mounted within the housing and spaced along the length of the housing for illuminating the surface, and a connector couples the LEDs to an electrical power source for energizing the LEDs to produce light that illuminates the surface.
