Embodiment Construction

[0032] figure 1 A sectional illustration of a motor vehicle headlight 10 with a light module 12 is shown. In other embodiments, the headlight 10 can also have a plurality of lighting modules 12 . The lighting module 12 has a semiconductor light source 14 , a primary optics 16 and a secondary optics 18 . The light module 12 is arranged in a housing 20 of the headlight 10 . The housing 20 has a light outlet that is covered by a transparent dust cover 22 .

[0033] The light source 14 is arranged on a carrier element 24 . Next to the light source 14, further electrical components and conductor circuits are arranged on the carrier element 24, which enable the power supply and control of the light source 14, but are not shown here for the sake of clarity. Electrical components and conductor circuits. The carrier element 24 is usually a rigid or flexible sheet and is usually in thermal contact with a cooling body, not shown in the figures, which is provided and arranged to abso...

Abstract

The invention relates to a motor vehicle headlamp (10) with at least one semiconductor light source (14) and a primary optical system (16) which collects light emitted from the semiconductor light source (16) and is directed to a secondary optical system (18), wherein the primary optical system (16) receives the light from the light source (14) via a light entry surface (26) and the light is emitted out via a light exit surface (28), wherein the primary optical system (16) has a connecting flange (42) with which the primary optical system is kept in a holder (34) in at least two fixed bearings (52), the fixed bearings are arranged in a first plane, which is parallel to a second plane, a distance (a) is arranged between the first plane and the second plane, and the light entry surface is arranged in the second plane. The motor vehicle headlamp is characterized in that a first section (44) of the connecting flange (42) is curved like a dome.

Description

technical field [0001] The invention relates to a motor vehicle headlight having the features of the preamble of claim 1 . Background technique [0002] Such a motor vehicle headlight is known from DE 10 2010 023 359 A1. The known headlight has at least one semiconductor light source and a primary optics system which is arranged to collect the light emitted by the semiconductor light source and direct it onto the secondary optics. For this purpose, the primary optical system absorbs light from the light source via at least one light entry surface and leaves it via the light exit surface. The primary optics has a connecting flange, by means of which the primary optics is held in the holder in at least two fastening mounts, which are arranged in a first plane parallel to the second plane and is spaced from a second plane in which there is at least one light incident surface. [0003] The light exit area of ​​semiconductor light sources for motor vehicle headlights is usuall...
