Cooling system of lighting apparatus using microwave energy

Abstract

In a lighting apparatus using microwave energy including a magnetron for generating microwave energy, a bulb for generating lights by the microwave energy, a wave guide for connecting the magnetron and the bulb and transmitting the microwave energy generated in the magnetron to the bulb and a casing housing the magnetron and the wave guide and combining with the bulb, a cooling system of a lighting apparatus using microwave energy comprises a heat exchanger installed to the exterior of a magnetron and having a coolant path, a radiating unit installed to the exterior of a casing and radiating heat of the coolant heated while passing the path of the heat exchanger, and a flow generating means installed between an outlet of the radiating unit and an inlet of the heat exchanger in order to make the coolant circulate the heat exchanger and the radiating unit.
