Problems solved by technology

[0016] However, these methods have the disadvantage of using an additional moving part in the headlamp and its actuator combination, thus increasing the complexity of the headlamp and, indeed, increasing the risk of wear and failure

Embodiment Construction

[0062] Before describing the method of distribution of the headlamp and the optical modules according to the invention, the different "sub-beams" and the complete beams obtained by the optical modules will first be described.

[0063] According to the first headlight configuration, which is to obtain a "full" beam, it is right-hand traffic and left-hand traffic type low beam. "Total light beam" should be understood as a complete light beam obtained by superposition of at least two sub-beams respectively emitted by at least two optical modules. Optical modules are defined above.

[0064] For this, 3 optical modules are used.

[0065] The first module, M1, produces a flat cut-off and thus obtains a "sub-beam" whose distribution is given by figure 1 Shown (with the most common isolux lines in the frame of reference, this coordinate system has two orthogonal axes defining four zones). It will be appreciated that the beam is distributed substantially symmetrically with respect t...

Abstract

#CMT# # / CMT# The device has a set of optical modules, each comprising a light source. One of the optical modules generates a first flat cut-off light beam (F1), and another optical module generates a partially oblique cut-off beam (F2), where the device emits total beams (Fg). One of the total beams is superposition of two of the beams emitted by the optical modules. A third optical module generates a second cut-off light beam (F3) approximately oblique and different from the partially oblique cut-off beam. #CMT# : # / CMT# An independent claim is also included for a method for installing a lighting device or a set of lighting devices. #CMT#USE : # / CMT# Lighting device i.e. headlight, for a car. #CMT#ADVANTAGE : # / CMT# The optical modules emit different cut-off light beams in a simple and safe manner without requiring mobile parts so as to avoid complexity of a headlight or risks of wear or malfunction of the headlight. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic view illustrating distribution of full road type complete luminous flux from a headlight. Fg : Total beams F1, F3 : Flat cut-off light beams F2 : Partially oblique cut-off beam YY' : Axis.

Description

[0001] This application is a divisional application based on the patent application with the application number 200610171865.X, the application date being July 26, 2006, and the invention name being "Motor Vehicle Lighting Device". technical field [0002] The invention relates to a lighting and / or signaling device of a motor vehicle, hereinafter referred to as a headlight for the sake of clarity. More specifically, the present invention relates to a headlight device capable of emitting a plurality of optical modules with light beams having different photometric characteristics. Background technique [0003] Different types of light beams already exist and are legally prescribed in practice. Some are mandatory, like high beam or low beam. Others are not mandatory at present, but can make the driver's field of vision more comfortable, such as fog light beams, or daytime light beams. [0004] A brief summary of the characteristics of most common beams is: [0005] - side li...
