    Abstract: An electrodeless plasma lamp and method of generating light is described. The lamp may comprise a lamp body comprising a dielectric material having a relative permittivity greater than 2. A lamp drive circuit is coupled to the lamp body and configured to provide radio frequency (RF) power to the lamp body. A bulb is positioned adjacent to the lamp body, the bulb containing a fill that forms a plasma when the RF power is coupled to the fill from the lamp body. The lamp drive circuit includes a control circuit to control the RF power to vary a temperature of the fill to emit light at adjustable output intensities. The control circuit may be configured to modulate a frequency of the RF power. In an example embodiment, the control circuit is configured to modulate the frequency in the range of 10 Hz to 10 KHz.
