Embodiment Construction
[0034] figure 1 A schematic, perspective side view of a lighting assembly 1 for a vehicle according to the invention is shown, having in this example two interconnected lighting sticks 2' and 2" (cf. Figure 3a and 3b) The photoconductor 2 and the intermediate element 3 are constructed. In principle, the number of light guides 2 can be selected arbitrarily. Starting from a common end region E which opens into the branch G, the light guide 2 branches off at the branch G into at least two light guide sections 4 ′ and 4 ″, which in the exemplary embodiment shown are connected to each other. Connected in a ring or in a rectangle with rounded corners. The common end region E has a main light propagation direction X, which, for example, can coincide with the direction of the longitudinal axis of the vehicle in the state installed in the vehicle. The light conductor section 4' and 4" have decoupling locations 5 shown in FIG. 3 for decoupling light. The intermediate element 3 is d...

The invention relates to an additional optical system for a beam splitter in an optical waveguide, a light module for a vehicle having at least one optical waveguide which proceeds from a common end region leading into a branching at Branching at the bifurcation into at least two light guide sections, wherein the common end region has a main light propagation direction, wherein the light guide section has one or more outcoupling locations for outcoupling light; and for Intermediate element for homogenizing the scattered light emerging from the at least one light guide at the branching, wherein the intermediate element extends between the at least two light guide sections and has a light entry surface and a light entry surface Opposite light exit surfaces for emitting light into the region between the light conductor sections, wherein the light entry surface of the intermediate element is spaced apart from the beam splitting point at the apex of the branching, In this case, the light entry surface is oriented approximately perpendicularly to the main direction of light propagation of the common end region.
Description
technical field [0001] The invention relates to a light module for a vehicle having at least one light guide branching off at a bifurcation into at least two light conductors starting from a common end region leading into a bifurcation The light guide section, wherein the common end region has a main direction of propagation of light, wherein the light guide section has one or more outcoupling points (Auskopplungsstelle) for outcoupling light; An intermediate element for homogenizing the scattered light exiting the at least one light guide, wherein the intermediate element extends between the at least two light guide sections and has a light entry surface and an opening facing the light entry surface. For emitting light into the light exit surface in the region between the light guide sections. Background technique [0002] Lighting assemblies are increasingly being used in vehicle construction, in which light from a light source is fed into light bars at the end faces. Th...
