Abstract
A light collection system comprises a light source with a bulbous section for emitting radiant energy in the direction of first and second portions of the bulbous section. A reflecting surface directs visible light from the light source to the first portion. Another reflecting surface directs UV energy from the light source to the second portion. A first angle-to-area converter receives visible light in the first portion and decreases the angle of the visible light to a desired angle. A second angle-to-area converter receives UV energy in the second portion and decreases the angle of the UV energy to a desired angle. A phosphor layer receives UV energy downstream of the second angle-to-area converter and converts the UV energy to visible light. A third angle-to-area converter receives visible light from the phosphor and reducing the angle of such light to an angle optimized for entering a fiber optic cable.
