Headlamp, especially for vehicle, has first terminating body intensity distribution cross-sectional variation, second curved cross-sectional variation at least over part of extent along optical axis

摘要

The device has a light source(s) and a terminating body for producing a light distribution with a base cross-section and light input and output coupling surfaces. A lens interacts with the output coupling surface. The terminating body has a first cross-sectional variation deviating from the base cross-section for intensity distribution and a second curved cross-sectional variation at least over part of its extent in the optical axis direction. The device has at least one light source and a terminating body (12) for producing a light distribution with a base cross-section, a light input coupling surface (22) and an output coupling surface (24). A lens (20) interacts with the output coupling surface. The terminating body has a first cross-sectional variation deviating from the base cross-section for intensity distribution and a second curved cross-sectional variation at least over part of its extent in the direction of the optical axis.
