Headlight having a pivoting elliptical reflector and a fixed lens, for producing an offset or verge beam

摘要

A headlight for providing a light beam adapted to illuminate the verge of the road. From the rear towards the front along a horizontal reference axis are an elliptical reflector, a light source, and a convergent lens element. The reflector and light source are mounted for pivoting movement, to provide a movable optical axis with respect to the longitudinal axis. The lens is fixed. A lateral portion arranged in an angular sector is swept by the movable optical axis, and is designed to cause the light beam to be modified as a function of the offset angle defined by the movable optical axis with the longitudinal axis.
