Abstract
An electrodeless lighting apparatus using microwave comprises: a waveguide for transmitting microwave generated in a magnetron; a mesh screen coupled to an outlet portion of the waveguide for blocking a leakage of the microwave and passing light; a bulb located in the mesh screen for emitting light by generating plasma by the microwave; and a globe installed on outer area of the mesh screen so that the light generated in the bulb can be radiated to omnidirection, that is, the globe is installed around the bulb instead of a reflector and a light guide which are used in the conventional art, and thereby, a structure of the lighting apparatus can be made simply and an omnidirectional lighting can be performed.
