Embodiment Construction

[0030] figure 1 Shown is a headlight 1 for a motor vehicle according to the prior art, consisting of a reflector 2 having approximately the shape of an open partial ellipsoid, in which a light source S is located, and a converging lens 3 Inside, the converging lens is placed before the reflector. The light source S is arranged at the first focal point of the ellipsoid on the side of the reflector 2 and emits light over the full solid angle formed by the ellipsoid. After reflection on the reflector 2, all emitted rays are directed towards the second focal point F of the ellipsoid.

[0031] On the optical axis x-x of the headlight 1, the lens 3 is arranged longitudinally at a position such that the focal point of the lens is approximately at the second focal point F of the ellipsoid. In order to straighten the light from the reflection part 2 , so that the light is approximately parallel to the optical axis when output from the lens 3 . Thus, the result obtained is that, in t...

Abstract

The present invention relates to a multi-module motor vehicle headlight comprising movable reflectors actuated by a single motor. The headlight (11) is of multi-module type and each module (11a, 11b) constituting said headlight (11) comprises at least one light source and at least one movable member for interrupting the light beam (4a, 4b) , the movable member is able to block a part of the light beam from the light source or allow a part of the light beam to pass according to its position, the blocking members (4a, 4b) of at least two modules are actuated by a common moving device, both The reflective surfaces of each module are flat mirrors (4a, 4b) mounted on a common axis (5) and able to rotate around said common axis (5), The common axis is oriented perpendicular to the optical axis.

Description

technical field [0001] The field of the invention is that of devices for motor vehicles, more particularly that of headlights for these motor vehicles. Background technique [0002] A headlight for a motor vehicle generally includes a reflector inside which there is a light source and means for controlling the shape of the light beam emitted by the light source to adapt the light beam to the driving environment. [0003] The reflector is generally in the form of a paraboloid or ellipsoidal revolution, for which reflector the light source is arranged at the foci of these surfaces or at one of the foci of these surfaces. In the case of an ellipsoid, conventionally, the light source is positioned at the first focal point and the lens is positioned on the optical axis so that the focal point of the lens itself coincides with the second focal point of the ellipsoid. In order to reduce the size of the headlight, it is envisaged that the vertical extension of the headlight can be ...
