ABSTRACT:
A backlit sign with an LED module, with a housing that includes a top wall having a first length, a bottom wall having a second length, and a pair of opposing sidewalls each having a third length, wherein at least a portion of one of the sidewalls is translucent. One or more LED modules are mounted to the top wall and include a plurality of LEDs for producing light. The first, second and third lengths are selected to maximize illumination of the sidewalls by the produced light, and to minimize a width and weight of the sign. A mirror can be used to increase the reflectivity of the bottom wall.
