Embodiment Construction

[0050] figure 1 The schematic design of a first embodiment of a lighting device 1 according to the invention is shown, which has a light module 2 and has at least one light emission source 10 or at least one light emission point 10 . For this purpose, the primary optics 100 connected here to the light emission source 10 has a light-conducting additional optics 102 made of a transparent material, which has a plurality of light conductors 102 , which are respectively It has a light entrance surface 101 and has a light exit surface 103 . The light beam 50 , which is outlined here with a dashed line, is conducted from the light exit surface 103 of the additional optics 102 to the secondary optics 300 , which is designed here as a lens entry surface 301 and a lens exit surface 302 . The projection lens 303 and this secondary optics are spaced from the primary optics in the direction of the optical longitudinal axis 150 . In the light path, the shutter 200 is arranged in the shutt...

Abstract

The invention relates to a lighting device (1) for a motor vehicle headlight, comprising a light module (2) with at least one light emission source (10), a primary lens (100) and a secondary lens (300), wherein said primary lens (100) comprises at least one light-conducting ancillary lens (102) which is designed to direct light (50) captured by the at least one light emission source (10) through at least one light-emitting surface (103) of the ancillary lens and on to the secondary lens (300) arranged downstream in optical longitudinal axial direction (150), and wherein the secondary lens (300) is designed to image a light distribution, which forms on the light-emitting surface (103) of the ancillary lens, in an area in front of the lighting device (1). At least one light-guiding shield (200) for shading a light color fringe (250) is arranged between the primary lens (100) and the secondary lens (300), wherein the at least one light-guiding shield (200, 201, 202) forms an optically active first aperture edge (221) for a lower light color fringe (252) and an optically active second aperture edge (222) for an upper light color fringe (251), and the optically active aperture edges (220, 221, 222) are each arranged in such a manner in the light beam (50) that blue defining light beams (51) of the light color fringe (250, 251, 252) can be selectively shaded.

Description

technical field [0001] The invention relates to a lighting device for a motor vehicle searchlight, the lighting device comprising a light module having at least one light emission source, primary optics and secondary optics, wherein the primary optics has at least one light source. Additional optics of a light guide, the additional optics are designed to further concentrate the light received by the at least one light emitting source through at least one light exit surface of the additional optics to a direction along the optical longitudinal direction. The axial direction is arranged on the rear secondary optics, and wherein the secondary optics are designed to image the light distribution occurring on the light exit surface of the additional optics to the illumination device located in front of it. in the front zone. Background technique [0002] It is known from the prior art that in optical lenses or in optical lens systems on the exit surface of the optical system, sho...
