Plasma lamp with light-transmissive waveguide

摘要

A lamp (10) may include a waveguide (18) having a solid dielectric body (19) and may have a bulb (22) disposed in the body (19). The bulb (22) may be adapted to produce light (24) when excited by electromagnetic energy (14). The waveguide body (19) may have at least a portion that is transmissive of light (24). The waveguide (18) may be configured to guide electromagnetic energy (14) recived from a source (16), and may have one or more apertures (40) adapted to allow light (24) to exit the waveguide body (19).
