Abstract
The headlight has a light source (12), a reflector (10), and a baffle (32) with a light admission opening (34), the baffle being disposed downstream of the reflector (10) in the light exit direction (30). The reflector (10) has a central reflector region (16), by which an at least approximately parallel fractional beam (20) is reflected, and at least one peripheral reflector region (24), by which a fractional beam (28) that converges in horizontal longitudinal planes (22) and is at least approximately parallel in vertical longitudinal planes (18) is reflected. The fractional beams (20, 28) are concentrated at least substantially on the light admission opening (34) of the baffle (32), whose cross section is smaller than the cross section of the reflector (10) at the front edge (36) of the reflector. The beam emerging from the headlight has pronounced horizontal scattering, despite the small cross section of the light admission opening (34) of the baffle (32).
