Abstract

An HID head lamp device capable of driving each of HID headlights by generating a high voltage at a secondary coil of a transformer by applying a starting voltage to a lamp firing circuit under the control of a control circuit when a lighting switch is turned on and maintaining the lighting of the HID lamp by applying a maintaining voltage to the secondary coil of the transformer after firing the HID lamp, which device composed of left and right head-lamp units, each unit formed by potting a lamp lighting circuit, a transformer assembly and a lamp socket in a housing with insulating resin poured in melted state and solidified therein, and a control unit for control the head lamp units, and which device is very compact, easy to mount on a vehicle body and easy to repair by exchanging only a faulty unit with new one when a fault such as a breakage of a circuit took place in the ECU or any of the lamp units.
