An improved lighting apparatus for providing uniform illumination to the surface of an object, primarily surfaces (14) with data in code or alphanumeric format, includes an area diffused light source (50) mounted interior to a light-shielding canopy (20). The area diffused light source (50) includes at least one electroluminiscent panel (52). The light shielding canopy (20) blocks out external sources of light, and has an interior surface that reflects light emitted by the electroluminiscent panel (52). In operation, the light-shielding canopy completely covers the surface of an object while diffuse, uniform light emanating directly from the elctroluminiscent panel (52) or reflected off the interior surface of the light-shielding canopy (20) illuminates the surface of the object. <IMAGE> |
