Embodiment Construction

[0022]Figure 1a , 1b and 1c show a perspective view of a light conductor module 100 according to the invention, the light exit surface 2 of which is formed by the distal ends 13 of a plurality of light conductor segments 1 (for reasons of clarity, only selected The light conductor segment 1 is assigned the associated reference numerals), and the light conductor module is delimited on the edge side by a flange 3 running around in the circumferential direction.

[0023] The light conductor segments 1 are arranged next to each other in a matrix, in the example shown there are 3×30 light conductor segments 1 , which are assigned to a corresponding 3×30 LED array in the associated luminaire. The cross-section of the light guide segment 1 can be circular or oval, for example, and / or can vary along the longitudinal expansion direction of the light guide segment 100 . In particular, as in the example shown, the cross section can continue to widen between the light incoupling surface ...

Abstract

The invention relates to a light guide module 100 for a primary optical assembly 200 of a motor vehicle lighting device. The light guide module 100 has a plurality of elongated light guide segments 1arranged next to one another, each having a proximal end 11 with a light coupling face 12 and a distal end 13. The distal ends 13 of the light guide segments 1 lead into a light exit face 2 of the light guide module 100 and a length X of the light guide segments 1 is defined by the distance between the proximal end and the distal end. The light guide module has a collar which surrounds the light exit surface at least in sections, wherein the collar has a local height that corresponds substantially to the length of the respective light guide segment nearest adjacent to the collar. The local height is defined by the distance between a proximal end section of the collar and a distal end section of the collar.

Description

technical field [0001] The invention relates to a light conductor module for a primary optics module of a motor vehicle lighting system, wherein the light conductor module comprises a plurality of elongate light conductor segments arranged next to one another, each of which has a distal end and a proximal end with a light coupling surface, wherein the far ends of the light conductor segments lead into the light exit surface of the light conductor module, and the lengths of the light conductor segments respectively pass through the defined by the distance from the distal end. Furthermore, the invention relates to a primary optics assembly of a motor vehicle lighting system, which comprises an optical waveguide module, a carrier frame and a fastening holder. Background technique [0002] In modern motor vehicle lighting systems, a plurality of light-emitting diodes (LEDs) are formed in a matrix arrangement as lighting devices, the light of which is guided through associated l...
