Abstract:
A lighting system using microwave comprising:a relay unit for receiving an AC power, and passing or cutting off the AC power according to a control signal; a high voltage transformer for transforming the AC power outputted from the relay unit into a high voltage AC power and outputting the transformed AC power; a voltage doubler unit for transforming the high voltage AC power into a high voltage DC power, increasing a frequency of a current of the DC power by at least more than twice, and outputting the high voltage DC power having the increased frequency; a magnetron for receiving the high voltage DC power from voltage doubler unit and generating microwave; a waveguide for inducing the microwave; an electrodeless light bulb for generating a stable light without a flicker phenomenon by the induced microwave; and a controller for generating the control signal.
