Light collection system for an electrodeless RF plasma lamp
Abstract:
An electrodeless plasma lamp and a method of generating light are provided. The plasma lamp may comprise a power source to provide radio frequency (RF) power and a lamp body to receive the RF power. The lamp body may include a dielectric material having a relative permittivity greater than 2. A bulb is provided that contains a fill that forms a light emitting plasma when the RF power is coupled to the fill. Collection optics is provided to direct the light along an optical path to an aperture, wherein the optical path includes at least one reflective surface and at least two refractive surfaces.
