  • Patent number: 5174649
    Abstract: A lamp includes one or more LED's which illuminate respective portions of a refractive lens element whose incident surface preferably includes portions of hyperboloids which translate the LEDs' emitted rays into substantially parallel beams within the lens element. The lens element's exit surface is preferably an array of facets configured to provide a desired beam spread pattern, allowing precise tailoring of the resultant output beam pattern. The plurality of facets also allows a larger area on the lamp to appear to viewers to be uniformly illuminated, thus providing full target size definition at a decreased cost and with reduced power consumption.
