Embodiment Construction

[0017] Embodiments of the vehicle headlamp according to the present invention will be described below with reference to the drawings.

[0018] The vehicle headlamp 1 has a synthetic resin lamp body 3 with a front opening and a lighting circuit box 2 integrally formed on the side. The front opening of the lamp body 3 is covered by a front cover 4 , and a reflector 5 is provided in a tiltable manner in the space between the lamp body 3 and the transparent front cover 4 . A discharge bulb 6 (refer to FIG. 1 ) is detachably attached to the rear center of the reflector 5 .

[0019] The lighting circuit box 2 is formed in a shallow container shape extending rearward from one side (right side in the illustrated embodiment) of the lamp body 3 and opening to the right side. The front end of the lighting circuit box 2 is integrally connected to the lamp body 3 via the connecting portion 7 . The connection part 7 is formed in a shape bulging toward the rear, that is, the vertical cross...

Abstract

A vehicle headlamp including a lamp body, a front cover that covers the front of the lamp body, a reflector disposed in the lamp body, a discharge bulb supported by the reflector, a lighting circuit assembly formed by housing a ballast circuit for lighting the discharge bulb and a starting circuit in a casing, and a power feeding connector connected to the lighting circuit assembly by a cord and removably coupled to the connector portion of the discharge bulb. A lighting circuit case that houses the lighting circuit assembly is integrally disposed on the lamp body with a connecting portion in between, the lighting circuit case is provided on the side of the lamp body, and the connecting portion is in a shape of a lateral U in vertical cross-section so as to allow the power feeding connector to pass through.

Description

technical field [0001] The present invention relates to a new type of vehicle headlamp. More specifically, it relates to support of a lighting circuit unit in a vehicle headlamp using a discharge bulb as a light source. Background technique [0002] There are vehicle headlamps that use a discharge bulb as a light source. [0003] In order to light the discharge bulb, a ballast circuit that raises the voltage of the battery mounted on the vehicle and converts it to an AC voltage and applies it to the discharge bulb, and a starter circuit that applies a high-voltage starting voltage required to start lighting are required. Usually, the ballast circuit and the lighting circuit are accommodated in a single box, and are integrally mounted and disposed on the vehicle headlamp as a lighting circuit unit. [0004] For example, as shown in FIG. 6 , a vehicle headlamp e is shown in which a reflector is arranged in a space formed by a lamp body a and a fro...
