Document Type and Number:
Japanese Patent JP2592005
Kind Code:
B2
Abstract:
An aimable vehicular headlamp system has a discharge lamp assembly to be mounted to a vehicle body via aiming screws. The discharge lamp assembly comprises a discharge lamp bulb, and a bulb carrier subassembly directly coupled, both mechanically and electrically, to the lamp bulb. Also included is a lighting circuit assembly comprising a ballast section for providing a high alternating voltage, and an igniter section electrically connected between the ballast section and the bulb carrier subassembly of the discharge lamp assembly for causing the lamp bulb to glow by an electric discharge. At least the igniter section of the lighting circuit is mounted to the discharge lamp assembly, typically on the back of a reflector included in the discharge lamp assembly, for joint movement therewith relative to the vehicle body during the aiming adjustment of the discharge lamp assembly. Consequently, the lighting circuit assembly can be electrically connected to the discharge lamp assembly without use of any such elongate cables or cords as have been conventionally employed to this end.
