<p>PURPOSE: A light adjusting circuit is provided to stabilize load by supplying operation voltage to a driving controller using a built-in battery. CONSTITUTION: A light adjusting controller (10) controls first AC voltage based on a light control signal and outputs second AC voltage. A rectifier (12) is connected to the light adjusting controller to convert the second AC voltage to DC voltage. A power controller (14) outputs driving voltage to drive load (22). A driving controller (16) controls the driving voltage through the power controller. A battery (18) controls the driving voltage through the power controller.
