ABSTRACT:
An electronic display includes a matrix of LEDs mounted to a circuit board and selectively operated to produce a message or image. A reflector matrix mounts to the circuit board and provides light pipes which extend forward from each LED to direct its light and provide protection. Potting compound is disposed in each light pipe and extends beyond the reflector matrix to provide a convex lens. In one embodiment the potting compound extends into a convex lens cover.
