ABSTRACT:
Provided is a waveguide system for an electrodeless lighting device, comprising a waveguide guiding microwave energy outputted from an antenna of a microwave generation means which is fixedly-inserted into an inner surface of the waveguide, and having a slot formed at an inner surface of the waveguide and communicated with a resonator where a bulb is positioned for supplying the microwave energy inside the resonator, a first stub protruded from one inner surface of the waveguide to be placed adjacent to the slot, for an impedance matching with the antenna and tuning with an output frequency of the antenna; and a second stub protruded from an inner surface of the waveguide at a certain interval with the first stub and extending a bandwidth together with the first stub for tuning with the output frequency of the antenna is varied according to an impedance variation of the antenna, thereby enabling a supply of a maximal microwave energy outputted from an antenna to the resonator, and assuring of a resonance stability.
