Abstract
A light emitting diode (LED) sign lighter is positioned to illuminate a sign. One or more LED modules on the LED sign lighter are directed toward different portions of the sign. Each LED module is configured with a reflector or over-optic to control the angle of the light emitted toward the sign. Each LED module includes an array of LEDs. The configuration of each LED module within the LED sign lighter helps to reduce the build-up of environmental contaminants on the LED module. The center section of the LED sign lighter includes a compartment for housing electrical components to power the LED modules. Heat sink fins are oriented along the back side of the LED sign lighter to provide thermal efficiency for the LED modules.
