LIGHTING SYSTEM USING PLASMA

摘要

An electrodeless lighting system comprises: a first case (200) in which a microwave generator (102), a waveguide (103) for guiding microwave energy and a luminous part (120) communicating with the waveguide, for emitting light by the microwave energy are installed, wherein one side of the first case is opened so that light from the luminous part (120) is emitted to the outside; a second case (300) coupled to the first case to open or close the opened one side of the first case and configured to pass the light from the luminous part; and a third case (400) positioned at one outer side of the first case (200), in which a high voltage generator (108) for supplying a high voltage to the microwave generator (102) is installed. Accordingly, in the electrodeless lighting system, lateral lighting can be made like a streetlight, heat generating components and lighting components can be installed at separated spaces, respectively, and the generated heat can be smoothly emitted to the outside.
