ELECTRODELESS LIGHTING DEVICE USING PLASMA

摘要

PURPOSE: An electrodeless lighting device using plasma is provided to prevent damage to an electrodeless bulb by installing at least one cooling pin to be vertically projected from the surface of a lighting unit. CONSTITUTION: A waveguide(40) guides the electromagnetic wave generated from a microwave generator. A resonator(50) is installed on one side of the waveguide and blocks the electromagnetic wave. The first holding portion(62) is protruded upwardly a place where the resonator is installed. An electrodeless bulb(60) comprises a lighting-emitting region which is connected to the first end of the first holding portion and generates light. At least one cooling fin member(133) are arranged on the surface of a lighting unit(61) by a certain interval.
