Abstract
A lighting apparatus which uses microwave energy which includes a microwave generator disposed inside a casing for generating microwave energy, a waveguide for transmitting the microwave energy, a resonator for covering an outlet of the waveguide, a bulb placed inside a resonator for generating light by the microwave energy transmitted through the waveguide, a conduction block in contact with the microwave generator for receiving heat generated in the microwave generating process, a heat transfer unit connected between the conduction block and the casing for transmitting heat from the conduction block to the casing and a radiating unit installed at the end of the heat transfer unit for radiating heat transmitted from the conduction block to the casing or outside of the casing.
