ABSTRACT:
A lighting apparatus using microwave comprises: a waveguide for transmitting microwave generated in a magnetron; a mesh screen installed on an outlet portion of the waveguide for blocking a leakage of the microwave and passing light; a bulb located in the mesh screen for emitting light by the microwave; a dielectric mirror installed on the outlet portion of the waveguide for reflecting the light emitted in the bulb forward parallelly; and a reflector installed around the mesh screen for reflecting the light emitted in the bulb forward, and the reflector and the dielectric mirror are constructed so that the light generated in the bulb can be radiated as parallel ray, whereby loss of light can be minimized and lighting efficiency can be improved.
