ABSTRACT:
A discharge lamp lighting controller that detects the voltage applied to a discharge lamp used by a vehicle, for example, and stops power supply to the discharge lamp if the voltage goes out of an estimated rated voltage range in a design stage. Circuit components are protected from possible impairment due to excessive current that may flow depending on the state of the discharge lamp under the constant power control of the discharge lamp.
