Abstract
An electrode-less plasma lamp, comprising generally of a bulb containing a gas-fill and light emitter(s) that is excited to produce light using radio-frequency (RF) energy. The present lamp includes compact air resonators/waveguides that use grounded coupling-elements with integrated bulb assemblies to reduce the size of the resonator and improve the performance of the lamp as well as reduce cost and simplify manufacturability.
