ILLUMINATION DEVICE FOR A SEALED-BEAM HEADLIGHT OF A VEHICLE, HAVING A LIGHT BEAM WHICH ENSURES CONSTANT ILLUMINATION OF AN OBSTACLE REGARDLESS OF THE POSITION THEREOF

摘要

The invention relates to an illumination device (DE) which is provided in a sealed-beam headlight (BO) of a vehicle (V) and includes a source (SL) which generates a light beam, and control means (MC) which are arranged such that, if an obstacle is detected at a point in a region located in front of the vehicle (V), said means vary the electrical supply from the source (SL) on the basis of the relative position of the obstacle in relation to the vehicle (V), so that the illumination of said obstacle by the light beam is substantially constant regardless of said relative position.
