Abstract
A fiberoptic lighting system has a light source with a bulbous section and a plurality of plastic light pipes having substantially circular cross sections. A collector has an inlet for receiving light from the light source and an outlet. The collector performs an area-to-angle conversion on light it collects from the light source. A plurality of rods receives light from the collector and passes such light to the plastic light pipes, while thermally isolating the plastic light pipes from the light source. A perimeter of an outlet of the collector has a plurality of shaped portions, each associated with, and each substantially shaped the same as, a substantial portion of an associated perimeter of a respective one of the plurality of rods. The foregoing system delivers a higher percentage of light from a light source into multiple light pipes than in a prior art system.
