PURPOSE: A driving apparatus of a lamp is provided to improve the lifespan and reliability of a lamp by sensing voltage through an open lamp controller to perform a protection operation. CONSTITUTION: A driving apparatus of a lamp includes a DC/DC converter(110), a light-emitting area(120), a sensor(130), and an open protection unit(140). The sensor senses the light-emitting area to output a feedback voltage to a controller. The controller controls the DC/DC converter. The open protection unit senses the light-emitting area and stops the operation of the controller. |
