Abstract
An electrodeless plasma lamp includes a bulb containing a gas-fill and light emitter(s) excited to produce light using radio-frequency (RF) energy. Input and output coupling elements separated from each other by a gap couple RF energy from an RF source to the bulb. One end of the input coupling element is electrically connected to an RF source while the other end is connected to ground. One end of the output coupling element is connected to ground while the other end is connected to the bulb.
