Optical panel for LED light source

摘要

An optics panel for use in a light emitting diode (LED) lighting is disclosed. A plurality of LEDs is disposed on a substrate and directed outward therefrom. A substantially transparent substrate is disposed over the plurality of LEDs and configured to direct light from each of the plurality of LEDs of the lighting assembly onto a surface having a predetermined bounded area. Light from each of the LEDs is directed by the transparent substrate across the entire area of the surface so that each LED illuminates substantially the entire surface with a substantially equal level of illumination per LED.

1. An optics panel for use in a light emitting diode (LED) lighting assembly for illuminating a billboard that has a display surface extending between outer edges of the billboard, the optics panel comprising:
a plurality of LEDs directed toward the display surface; and a plurality of optical elements, each optical element disposed over only one associated LED and configured to direct light from that LED toward the display surface, such that the light from each LED is directed across the entire display surface of the billboard so that, for each LED, a ratio of the average illumination from that LED across the entire display surface to the minimum illumination from that LED at any point on the display surface is 3:1.
