摘要： A process and apparatus is described to produce efficient light emission over a broad portion of the visible spectrum. A lens (240) containing a fluorescent dye is over molded to a short wavelength light emitter (110) such as a blue LED or laser diode placed within a reflector cup (120). The fluorescent dye absorbs at least a portion of the light emitted by the diode (110) and re-emits light of a second, longer wavelength. Concentration of the dye within the lens (240) can be varied to control the extent of a region within the lens where most of the light is re-emitted. One can readily and consistently tailor the color of the light emitted from the lens (240) through selection of the number and types of fluorescent dyes added to the lens.
