Abstract
A visual display sign having a lighting unit. The reflector in the lighting unit is nearly completely sealed and has a reflecting surface that spreads the emitted light about eight degrees from the plane of circumference of the reflector. To cool the lighting unit, air is directed along the rear surface of the sealed reflector. A small amount of the air enters the sealed reflector, causing a buildup of pressure inside the reflector and preventing any additional air from entering the reflector. This cooling system minimizes dust buildup on the reflective and light-emitting surfaces inside the reflector. The lighting units are attached to the visual display sign at a downward angle of about eight degrees from the horizontal.
