Abstract:
An LED display reflector comprising:at least one light emitting diode; an optically opaque base plate having upper and lower surfaces, said optically opaque base plate having a passage formed therethrough, said passage defining an outer display periphery; an optically opaque display member having upper and lower surfaces and being received within said passage of said optically opaque base plate, said upper and lower surfaces of said optically opaque display member being substantially co-planar with said respective upper and lower surfaces of said optically opaque base plate, said optically opaque display member defining an inner display periphery, said inner and outer display peripheries being spaced apart each from the other; and, a rib member fixedly secured to said lower surfaces of said optically opaque base plate and said optically opaque display member, respectively, said rib member maintaining a transmission space formed between said inner display periphery and said outer display periphery, whereby light emitted by said at least one light emitting diodes impinges on said lower surfaces of said optically opaque base plate and said optically opaque display member, said light being transmitted through said transmission space and being reflected between said optically opaque base plate and said optically opaque display member such that said light appears to have a substantially uniform intensity when transmitted beyond said upper surfaces of said optically opaque base plate and said optically opaque display member, said inner and outer display peripheries being selectively contoured for producing desired light patterns and effects.
