Abstract
An apparatus includes a display surface having a substantially rectangular region with a width of twenty-four feet. The region of the display surface has visual media content displayed thereon. A first lighting unit includes a number of light emitting diodes (LEDs) and optical elements arranged over the plurality of LEDs such that each optical element overlies only one associated LED. The first lighting unit is configured to illuminate the region of the display surface so that the visual media content on the region of the display surface can be viewed without additional lighting. A second lighting unit is laterally spaced from the first lighting unit along the width of region of the display surface. The second lighting unit includes a number of LEDs and optical elements arranged over the plurality of LEDs such that each optical element overlies only one associated LED.

10. An apparatus comprising:
-
a display surface having visual media content located thereon; and a lighting assembly that comprises a first lighting unit and a second lighting unit; wherein the first lighting unit includes a first circuit board, a first plurality of LEDs arranged on the first circuit board, and a first plurality of optical elements; wherein the second lighting unit includes a second circuit board, a second plurality of LEDs arranged on the second circuit board, and a second plurality of optical elements; wherein each optical element of the first plurality of optical elements and the second plurality of optical elements overlies a respective one of the LEDs, each optical element being configured to redirect light from the respective one of the LEDs; wherein the lighting assembly is configured to simultaneously direct light from the first lighting unit and the second lighting unit so as to illuminate a portion of the display surface; wherein the illuminated portion of the display surface is substantially rectangular; wherein the lighting assembly is configured so the portion of the display surface is illuminated in a manner that avoids light pollution; wherein the lighting assembly is configured so that the light from the first lighting unit and from the second lighting unit illuminates the visual media content on the portion of the display surface so that the visual media content on the portion of the display surface is visible even without additional lighting; and wherein the lighting assembly is configured so that if one or more LEDs of the first plurality or the second plurality of LEDs fails, remaining LEDs of the first plurality or the second plurality of LEDs still illuminate the portion of the display surface so that the visual media content on the portion of the display surface remains visible even without additional lighting. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
a lighting assembly configured to illuminate a substantially rectangular region, the lighting assembly comprising a first lighting unit and a second lighting unit; wherein the first lighting unit includes a first circuit board, a first plurality of LEDs arranged on the first circuit board, and a first plurality of optical elements; wherein the second lighting unit includes a second circuit board, a second plurality of LEDs arranged on the second circuit board, and a second plurality of optical elements; wherein each optical element of the first plurality of optical elements and the second plurality of optical elements overlies a respective one of the LEDs, each optical element being configured to redirect light from the respective one of the LEDs; wherein the lighting assembly is configured to simultaneously direct light with a substantially rectangular wavefront from the first lighting unit and the second lighting unit toward the substantially rectangular region; wherein the lighting assembly is configured so that the light is directed so that areas beyond edges of the substantially rectangular region receive minimum illumination from the lighting assembly; wherein the lighting assembly is configured to direct the light toward the substantially rectangular region such that the light from the first lighting unit and the second lighting unit illuminates the substantially rectangular region with an illumination level and a uniformity; and wherein the optical elements are configured so that failure of one or more LEDs of the lighting assembly will cause the illumination level of light impinging the substantially rectangular region to decrease while the uniformity of light impinging the substantially rectangular region remains substantially the same. - View Dependent Claims (20, 21, 22, 23, 24)
