Abstract
A visual display lighting system of a series of individual lighting modules. Each of the lighting modules having a printed circuit board containing drive circuitry and a plurality of light sources. Each module having a lighting panel which includes a reflector unit for each light source and a covering lens. A pair of retainer strips lock to the opposing ends of the lighting panel to hold the module in the display lighting system. The retainer strips quickly release from the opposing ends when the module is removed from the front of the visual display lighting system. In each module, the lighting panel has retainer clips for locking to the printed circuit board. When locked in place the board holds the plurality of light sources into the lighting panel for illumination of the sign. The printed circuit board can be quickly released from the lighting panel so that the board with the light sources can be removed from the rear of the visual display lighting system. In this event, the lighting panel continues to be locked to the pair of retaining strips.
