AI Technical Summary

Problems solved by technology

However, this is rather complex and in most cases involves a complete modification of the overall design of the headlamp, which requires considerable human, technical and financial means, resulting in development times that are often incompatible with the requirements of the car manufacturers

example 1

[0079] Example 1: Method of partially treating a part of a headlamp housing

[0080] The part, a shell made of polypropylene filled with 36% by weight of mica, is implemented by injection moulding. The part is inserted into a chamber equipped with ion implantation equipment including a system for scanning through a controlled electrostatic lens.

[0081] The parameters of ion implantation are as follows:

[0082] Gas: Helium

[0083] Source: ECR (Electron Cyclotron Resonance) / Microwave

[0084] Process energy received by the part: 20keV

[0085] Ion dose: 10 16 Ions / cm²

[0086] Processing time: 3s / cm 2

[0087] Surface area of ​​beam: 1cm 2

[0088] Working pressure (P): 1×10 -3 mbar

example 2

[0089] Example 2: Comparative test of a headlamp according to the invention

[0090] Measurements are taken in such as Figure 4 The headlamps described (HCPP+treated HCPP) were carried out on headlamps with their housings made entirely of commonly used polypropylene filled with 40% mica (PPT40) and whose housings were not locally treated Compared with headlights made of high crystalline polypropylene (HCPP).

[0091] A. Pedestrian strike

[0092] The pedestrian impact test refers to the impact test of a headlamp fixed to a vehicle body support to which a striker representing a pedestrian is applied. Such tests are usually defined in national regulatory directives.

[0093] The calculations are performed using an explicit finite element processing software application suitable for calculating short duration impacts. The calculation methods used allow predictive calculations to be performed depending on the results of the tests involved. The results obtained are descri...

Abstract

The present invention relates to a component of a motor vehicle lighting (1) and / or signalling device, comprising a polymer-based material, characterized in that this material has, locally on one side, a region (45) of increased crosslinking over a surface thickness.

Description

technical field [0001] The invention relates to a lighting and / or signaling device component, in particular a headlight component, for a motor vehicle. Background technique [0002] Illumination and / or signaling devices are known which comprise a plastic housing, an external lens and an optical module, each of which is fixed to the housing. The plastic housing is secured to the chassis of the vehicle via fixing brackets on the housing. Optical modules include lamps, reflectors and lenses in order to emit the light beam that needs to be adjusted correctly. Lighting devices such as headlights may include support plates. In this case, the optical module is fixed to a support plate which is itself fixed to the housing. In either embodiment, the light beam is adjusted by adjustment points located on the housing. [0003] Thereby, the light beam is adjusted for an arrangement of the optical module relative to the housing (via the support plate or other means) and for an arrang...
