Abstract

A billboard includes a support structure and first and second lighting assemblies. Each lighting assembly includes a number of circuits boards arranged in a common orientation. Each circuit board of the first lighting assembly is planar and has a number of LEDs and optical elements attached thereto. The LEDs are thermally coupled to a first heat sink. The LEDs are arranged in rows on each circuit board, with each row including a number of LEDs mounted so that all of the LEDs are arranged in a common orientation. Each optical element is disposed over only one associated LED. The optical elements are arranged to direct the light across a portion of the display surface.
