Abstract
An electrodeless lighting system includes: a resonator which is installed at an exit of a wave guide for guiding microwave generated from a magnetron and making light pass and microwave resonate therein; a bulb positioned in the resonator and having a luminous portion filled with a luminous material emitting light by the microwave energy and a shaft portion integrally extended from the luminous portion; a resonance control member disposed inside the resonator and having a height controlled according to a position of the luminous portion of the bulb and the entire length of the resonator so as to make optimum resonance of the microwave; and a reflector positioned around the resonator for reflecting light emitted from the bulb. Accordingly, the electrodeless lighting system can facilitate light distribution for achieving lateral lighting and a wider range of lighting and simultaneously improve lighting efficiency.
