Patent ID: 6926430

Claim:
A safety device for a lamp for a motor vehicle, the lamp comprising at least: a light source associated with a reflector for producing a light beam characterised in particular by an instantaneous direction contained in a horizontal or substantially horizontal plane; a mechanism for horizontal displacement of the light beam comprising in particular a first motor for making the instantaneous horizontal direction of the light beam change position; and a system for automatic correction of an illumination range of the lamp comprising in particular a second motor, or a device for controlling the trim of the vehicle, for making the light beam change position vertically, wherein the correction device comprises: a position sensor for determining an item of information relating to the instantaneous direction of the light beam; and a computer for comparing the item of information relating to the instantaneous horizontal direction of the light beam and a light beam horizontal displacement control, said computer activating the second motor of the automatic illumination range correction system or the vehicle trim control device in order to orient the light beam downwards when the item of information relating to the instantaneous direction of the light beam and the light beam horizontal displacement control are not in agreement and the value of a defined angle (α) between a reference direction and the instantaneous direction is greater than the value of a reference angle (αr), the reference angle (αr) being defined between the reference direction and a non-dazzle limit direction.
