摘要: 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 area diffused light source (50) mounted interior a light-shielding canopy (20). The at least one electroluminiscent panel (52). shielding (20) blocks out external sources light, and has that reflects emitted by In operation, completely covers object while diffuse, emanating directly from elctroluminiscent (52) reflected off illuminates object.
