Claim:
1. A billboard comprising: a support structure; a display surface mounted on the support structure, the display surface having visual media content displayed thereon, the visual media content comprising a picture and/or text, wherein the display surface has a width of forty-eight feet along an upper edge and a lower edge of the display surface and a height of fourteen feet along a left side edge and a right side edge of the display surface, the display surface comprising a first portion extending from the lower edge to the upper edge adjacent the left side edge and a second portion extending from the lower edge to the upper edge adjacent the right side edge, the first and second portions together extending from the left side edge to the right side edge; a first lighting assembly that includes a plurality of circuits boards arranged in a common orientation, each circuit board of the first lighting assembly being planar and having a first plurality of light emitting diodes (LEDs) and a first plurality of optical elements attached thereto, the first plurality of LEDs being thermally coupled to a first heat sink, wherein the LEDs of the first plurality of LEDs are arranged in a plurality of rows on each circuit board, each row including a plurality of LEDs mounted so that all of the LEDs of the first lighting assembly are arranged in a common orientation, and wherein each optical element of the first plurality of optical elements is disposed over only one associated LED, the optical elements being arranged to direct the light from each LED across the first portion of the display surface, wherein all of the circuit boards of the first lighting assembly are mounted in a single assembly; and a second lighting assembly that includes a plurality of circuit boards arranged in a common orientation, each circuit board of the second lighting assembly being planar and having a second plurality of LEDs and a second plurality of optical elements attached thereto, the second plurality of LEDs being thermally coupled to a second heat sink, wherein the LEDs of the second plurality of LEDs are arranged in a plurality of rows on each circuit board, each row including a plurality of LEDs mounted so that all of the LEDs of the second lighting assembly are arranged in a common orientation, and wherein each optical element of the second plurality of optical elements is disposed over only one associated LED, the optical elements being arranged to direct the light from each LED across the second portion of the display surface, wherein all of the circuit boards of the second lighting assembly are mounted in a single assembly, wherein the display surface can be illuminated using only the first lighting assembly and the second lighting assembly so that the visual media content can be viewed without additional light.
