摘要：
A driving device of a light source includes an arc sensing unit and an inverter. The light source includes a lamp having a first terminal and a second terminal. The arc sensing unit extracts a high frequency component from a voltage applied to the light source and generates an arc sensing signal in response to the high frequency component. The inverter controls the light source in response to the sensing signal.
