Abstract
An electrode-less plasma lamps, comprising generally of a bulb containing a gas-fill that is excited to produce light using radio-frequency (RF) energy. In specific embodiments, the use of grounded coupling-elements with integrated bulb assemblies simplifies manufacturability, improves resonant frequency control, and enables the use of solid, partially filled, and hollow lamp bodies.
