Headlight Vibration
LaserCam makes it possible to measure and document the stability of the Light-Dark-Border of a Headlight automatically. The aquired data is a valuable tool for the contineous enhancement of headlight systems.
A five minute fully automatic measurement using LaserCam delivers the designing engineer with a declination over frequency diagram as shown underneath. This makes LaserCam a quick measuring tool to check the effectivness of contruction changes upon the vibratory behaviour of the headlight system. The valuable information won using LaserCam also enables the designing engineer to optimize the finite elements models by comparing the simulated and real vibration tests.
High Tech without end
Headlights are meanwhile high tech products. While the illuminating engineering from the lamp over the halogen light finally developed to the xenon projector, the manufacturers go now a further step making the light cones arrangeble with means of motors: The keyword is called adaptive forward Lightening (AFL). Beyond the adjustment of the width of the light beam this concerns also the active curve light, with which the light cone is adjusted as a function of the respective steering wheel position and the speed into the respective curve. The new AFL Bi xenon headlights exhibit besides a so-called bending light, which can be activated at speeds under 50 km/h. This not enough: The cross-linking of adaptive lighting units with satellite-based navigation systems is already suggested. Afterwards the current courses of the curve will be called up in advance and the headlights are prepared optimally for the coming curve. The multiplicity of the headlight innovations has a common purpose: To make driving a car under the most difficult conditions as safe as possible. The numerous actuators and mechanisms, which affect the optical components of the headlight, lead however unfortunately to elastic constructions enforcing a greater deflection of the light when the vehicle is exposed to oscillations, a headlight of anno Tobak would admit.
Quality assurance
The increasing complexity of the headlights raises also the inspection costs in the context of the quality assurance. LaserCam supports the headlight manufacturers in the context of the quality assurance of the goods issue and the vehicle manufacturers in the context of the quality assurance of the goods receipt. In the first case LaserCam controls electrodynamic shakers, on which single headlights are fixed. In the second case complete vehicles are shaked by hydraulic shakers. LaserCam documents the measurement result delivering a quick overview and a complete Information on the behaviour of the headlight for the frequency band of interest.
