ABSTRACT:
Disclosed is a cooling structure for a plasma lighting system comprising a fan housing having at least two discharge ports having different flow rates for introducing external air into a case and cooling heat generating components in the case. The structure intensively cools heat generating components of high temperature such as a magnetron, thereby prolonging a life span of the components and enhancing a performance of a system.
