PLASMA LIGHTING DEVICE

摘要

PURPOSE: A plasma lighting device is provided to achieve improved cooling efficiency by generating a chaos flow from the cooling air in the lighting device. CONSTITUTION: A plasma lighting device comprises a chaos generating protrusion(120) protruded from an air outlet port(111) of an air guide duct(100). The chaos generating protrusion generates a chaos flow in the air flowing in the plasma lighting device. The chaos generating protrusion is extended from the side wall of the inner end of the air outlet port of the air guide duct and protruded to the center of the air guide duct. The air guide duct having an air inlet port(14) is arranged in a casing(1) so as to release the heat generated from a high voltage generating unit(2) and a microwave generating unit(3).
