Abstract
An RF electrode-less plasma lighting device has a base member, which includes an outer region capable of being coupled to first AC potential and an inner region capable of being coupled to a second AC potential. In a preferred embodiment, the device has an RF module mechanically and integrally coupled to the base member. The RF module has an RF source, which has an output. The RF module has a first DC input and a second DC input. The first DC input of the RF module is coupled to a first DC potential and the second DC input of the RF module is coupled to a second DC potential. In a specific embodiment, the present device has an RF electrodeless plasma lighting assembly integrally coupled to the base member. The RF plasma lighting assembly has an RF input, which is coupled to the output of the RF source.
