Embodiment Construction

[0019] exist figure 1 and 2 A housing according to a preferred embodiment of the present invention is shown in . The housing is basically formed as a cuboid and is very flat, approximately in the shape of a sheet. The housing has a large surface 200 and four side walls 300 , 301 , 302 , 303 . The above-mentioned six faces of the housing form a closed inner cavity, in which the components for driving the ballast of the metal halide vapor high-pressure discharge lamp are arranged on a mounting plate (not shown), the metal halide Vapor high-pressure discharge lamps are used as light sources in vehicle headlights. The mounting plate extends parallel to the front 100 and rear 200 of the housing. The edges between the side walls 300 , 301 , 302 , 303 are rounded. The housing consists of two magnesium die-cast parts connected to each other by means of screws 41 , 42 , 43 , 44 . The housing has a recess 110 running annularly on the outside of the front side 100 parallel to the e...

Abstract

In various embodiments, a housing for a ballast for operating a discharge lamp provided as a light source for a vehicle headlamp includes a housing forming an inner chamber to accommodate electrical components of the ballast, the housing configured such that it has an annular circumferential recess on its exterior, in which is arranged a sealing ring and on which fasteners are provided for the ballast, the fasteners being arranged outside the area on the exterior of the housing enclosed by the annular recess and the sealing ring.

Description

technical field [0001] The invention relates to a housing for a ballast for operating a discharge lamp designed as a light source for a vehicle headlight. Background technique [0002] Such housings are disclosed, for example, in publication WO 2005 / 034589 A2. Said document describes a housing for operating a ballast of a metal-halide vapor high-pressure discharge lamp designed as a light source for a vehicle headlight. The housing consists of two halves forming an interior cavity for housing the electronic components of the ballast. The interior is sealed by means of an O-ring surrounding the periphery between the two housing halves. [0003] The housing has the disadvantage that direct fastening of the housing to the vehicle headlight and sealing against the vehicle headlight are not possible. Contents of the invention [0004] The object of the present invention is to provide a housing which does not have the above-mentioned disadvantages. In particular, the housing...
