Embodiment Construction

[0024] The object of the invention is in particular to provide a lighting device DE for fitting on an optical unit BO of a vehicle V and for illuminating in a dedicated manner the Obstacle OB.

[0025] In the drawings, direction X is the longitudinal direction of the vehicle V substantially parallel to the sides respectively including the side doors, direction Y is the transverse direction of the vehicle V substantially perpendicular to the sides, and The direction Z is the vertical direction of the vehicle, which is perpendicular to the longitudinal direction X and the transverse direction Y.

[0026] In the following, as a non-limiting example, it is considered that the optical unit BO is intended to be fitted on a motor vehicle. But the invention is not limited to this type of vehicle. The invention relates in fact to any type of vehicle equipped with at least one optical unit comprising lighting means.

[0027] Also, in the following, as a non-limiting example, the opti...

Abstract

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.

Description

technical field [0001] The invention relates to a lighting device fitted on some vehicle optical units for illuminating obstacles detected in the area located in front of the vehicle. Background technique [0002] As is known to those skilled in the art, some vehicles include at least one optical unit equipped with a lighting device sometimes referred to as a "marking light" and comprising a light source sending a beam of light and control means, said The control means is configured to operate the light source when an obstacle is detected at a location in the area in front of the vehicle such that the light source dynamically illuminates the detected obstacle. When an obstacle is illuminated by a dedicated light beam, the driver spends more time performing an operation for avoiding the obstacle, and thus this can reduce the possibility of collision. [0003] The light beam is projected forward through at least one lens, or reflected forward by a rotating mirror. Obstacles ...
