US 5,509,223 A · Lighting system

Abstract

A lighting system (10) is provided to allow a plurality of overlapping virtual images (16-16"') to be viewed by an external observer. Lighting mechanisms (18) are positionally located adjacent reflectors (20) to form virtual images (16-16"') and provide a wide solid band of lighting to be viewed by the observer. Housings (32 and 32') enclose the combination of the light mechanism (18) and reflectors (20) and a sign member (12) is formed on a frontal wall for viewing of particular indicia (14) formed on or through sign member (12). Reflector (20) may be bonded to a reflector support (38) fixedly mounted within housing (32). A color transmissive housing may be mounted over light mechanism (18) to provide a particular color to be passed external to housings (32 and 32'). In this manner, the external observer is provided with a substantially constant illumination density for light emission from light mechanism (18) passing through a sign member (12).

Claims8

Dependent claims

A lighting system comprising:

(a) light means for emitting electromagnetic radiation within the visible bandwidth, said light means having a predetermined first diameter dimension;
(b) a reflector member having a concavely contoured inner reflective surface, said reflector member inner reflective surface having a substantially semi-circular contour formed by a plurality of linear sections, said light means being positionally located between a focal point of said reflector member and said inner reflective surface for producing a plurality of intersecting virtual images of said light means viewable external said lighting system in an overlapping pattern for providing a substantially wide angle constant illumination pattern, said reflector member having a second diameter dimension approximating three times said predetermined first diameter dimension;
and,
(c) housing means for substantially encompassing said light means and said reflector member, said housing means defining a rear section for mounting of said reflector member therein.
