Abstract
In one aspect the plasma lamp according to the present invention comprises a gas envelope that is constructed from ceramic material and a sapphire window rather than quartz. According to another aspect of the present invention, a plasma lamp comprises an RF structure for the radio wave radiation and an envelope for housing the excitation gas that are formed so as to constitute a single, integrated ceramic structure. According to yet another aspect of the present invention, the plasma lamp comprises a waveguide structure having solid material such as ceramic rather than air for the dielectric and a gas housing made of a combination of solid ceramic and a sapphire window. In this way, the separate quartz gas envelope and air-filled waveguide structure employed in the prior art are replaced by a single, integrated structure.
