Embodiment Construction

[0033] figure 1 Shown is the projection unit 20 according to the invention, in particular the optical module 21 of the overall configuration of the projection unit 20 . The shown optical module 21 is designed in particular to provide at least partially, preferably completely, the projection function of the entire projection unit 20 . For this purpose, the optical module 21 , in particular its integral base body 30 , has an entrance section 31 through which an input light beam 50 can enter the interior of the base body 30 in an input direction 60 . The base body 30 also has at least one reflective section 32 , 33 , preferably two reflective sections 32 , 33 as shown. The incident light beams are internally reflected at the reflective sections 32 , 33 and are arranged in particular in the direction of the exit section 35 . A beam of light is emitted again in output direction 61 from exit section 35 as output beam 51 . As shown, in particular due to the presence of the reflec...

Abstract

The invention relates to a projection unit (20) for a headlamp (1) of a vehicle for providing an optical projection function, said projection unit (20) having an optical module (21). The invention further relates to a headlamp (1) for a vehicle, comprising a light source unit (10) for providing an input light beam (50) and a projection unit (20) for providing an optical projection function, said light source unit (10) comprising a light source (11) and a light source optical device (12), so an input light beam (50) can be projected as an output light beam (51) by a projection function.

Description

technical field [0001] The invention relates to a projection unit for a headlight of a vehicle for providing an optical projection function, the projection unit having an optical module. Furthermore, the invention relates to a headlight for a vehicle having a light source unit for providing an input light beam and a projection unit for providing an optical projection function, the light source unit having a light source and a light source optics , the input beam can be projected as an output beam through the projection function. Background technique [0002] In today's vehicles it is known in principle to install projection units in the headlights. By means of such a projection unit, the input light beam provided by the light source can be changed, shaped and then projected outwardly beyond the headlight. In this way, a particularly diverse and also particularly precisely defined provision of the lighting function of the headlight can be achieved. It is known in particula...
