Abstract

A lighting device is provided with a power circuit part (23) which comprises power terminals (25, 25, 25) supplied with power from a power source, harnesses (29, 29, 29) which supply a discharge lamp (9) with the power supplied to the power circuit part, a terminal housing (34) which is formed of resin material, has respectively one ends of the harnesses arranged inside, and comprises a harness holding part (48) inside for holding the respectively one ends of the harnesses, and welded terminals (28, 28, 28) composed of portions arranged inside of the terminal housing and portions projecting outward from the terminal housing. The one ends ofthe welded terminals are joined respectively with the one ends of the electric wires of the harnesses, and the other ends of the welded terminals are respectively welded to the power terminals of the power circuit part. This improves workability of connection work with the power circuit part and secures the satisfactory connection of the harnesses.

Description

technical field [0001] The present invention relates to a lighting device preferably used for a discharge lamp. More specifically, it relates to a technical field in which a terminal case is provided to hold a plurality of bundles of electric wires respectively connected to a plurality of soldering terminals to improve workability of a connection operation with a power circuit unit. Background technique [0002] In some vehicle headlamps, a discharge lamp provided as a light source and a lighting device for lighting the discharge lamp are arranged in a lamp chamber formed by a front cover and a lamp body. [0003] This lighting device has a power circuit part that supplies power to a bulb socket for installing a discharge lamp or a so-called starter used as a discharge lamp starting device. socket or starter connection. [0004] When using a plurality of wire bundles as the connection wires, one end of each wire bundle is connected to each power terminal of the power circu...
