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. In an example, the lamp is configured with an rf feed that is substantially normal to a direction of the bulb and associated support member.
