PURPOSE: An illuminating system using microwave is provided, in which electric bulb, magnetron, high voltage generator and the cooling fan are arranged in line, to thereby allow the illuminating system to be easily installed in a narrow space. CONSTITUTION: An illuminating system using microwave, comprises an electric bulb(50) for emitting light by the microwave transmitted through a waveguide; a resonator(60) covering front portions of the waveguide and the electric bulb, and which allows the light emitted from the electric bulb to exit but is opaque to microwave radiation; a magnetron(20) mounted within a casing(10), and which generates microwave for allowing the electric bulb to emit light; and a high voltage generator(30) mounted within the casing in such a manner that the high voltage generator supplies a high voltage power to the magnetron.
