Light guide module for a primary optical assembly of a motor vehicle lighting device with collar having height that corresponds to length of a light guid segment and primary optical assembly having the same

Abstract

A light guide module for a primary optical assembly of a motor vehicle lighting device. The light guide module has a plurality of elongated light guide segments arranged next to one another, each having a proximal end with a light coupling face and a distal end. The distal ends of the light guide segments lead into a light exit face of the light guide module and a length of the light guide segments is defined by the distance between the proximal end and the distal end. A collar extends at least in sections around the light exit face, 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.
