Abstract:
An electrodeless lighting system, comprising:a case; a waveguide, in which an exit is exposed out of the case, installed in the case for transmitting a microwave generated in a magnetron; a bulb located outside of the exit of the waveguide and emitting light as generating plasma by the microwave transmitted through the waveguide; a resonator having a protecting member formed of a non-reticular structure and a reticular member, the protecting member being formed as a cylindrical shape and fixed on the exit of the waveguide so that the walls of the protecting member completely surround the bulb for making a resonating area in which the microwave is resonated, and formed to endure heat generated from the bulb, and the reticular member being formed as a cylindrical shape and connected to the protecting member over the bulb so as to prevent leakage of the microwave and pass the light generated from the bulb.
