ABSTRACT:
A plasma lamp for an electrodeless plasma lamp having a dielectric waveguide body and a bulb positioned, at least in part, in the waveguide body and having at least one end protruding from the waveguide body. A probe is used to couple power into the waveguide body. The power resonates in the waveguide body and ignites a plasma in the bulb. By having one or both ends of the bulb extend beyond the surface of the waveguide body, the ends of the bulb are exposed to reduced electric field intensity, resulting in longer bulb lifetime due to reduced plasma impingement on the interior surfaces of the bulb.
