Electrodeless lighting system

摘要

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 the 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 protecting member fixed on the exit of the waveguide around a boundary portion of the bulb for making a resonating area in which the microwave is resonated, and formed to endure the heat generated from the bulb; and a resonator connected to the protecting member on front side of the bulb and having a reticular portion so as to prevent the leakage of the microwave and pass the light generated from the bulb, and thereby, discoloring or burning of a mesh portion of the resonator by the high temperature generated from the bulb can be prevented and therefore the leakage of the microwave in the resonating area, accordingly stability of the lighting system can be improved and life span of the resonator can be increased.
