Embodiment Construction

[0023] according to figure 1 The lighting device has a plurality of light sources 1, a light-shaping optical unit 3 located in front of the light sources 1 along the main illumination direction 2 of the lighting device, and a diffusing optical unit 4 arranged between the light-shaping optical unit 3 and the light source 1. The lighting device is used, for example, as a headlight of a vehicle. The lighting device can be used in particular to form addressable high beams, dynamic turn indicators and other variable light distributions.

[0024] The light sources 1 are arranged in a matrix in the light-generating surface 5 . For example, 30 light sources 1 are arranged in three columns. It is also possible to arrange 80 or more light sources 1 in the light-generating surface 5 . In particular, light-emitting diodes can be provided as light sources 1 .

[0025] The light source 1 is preferably arranged on a shared circuit carrier. To dissipate the heat, the light-emitting diode...

Abstract

A lighting device for vehicles with multiple light sources arranged like a matrix in one light generation level, with a light forming optic unit arranged in front of the light sources, and with another optic unit arranged between the light forming optic unit and the light sources, comprising a plurality of optic elements that are arranged like a matrix and one optic element each being allocated at a face thereof to a light source and with the other optic unit in front of the optic elements being allocated to the light sources to coupling areas and at least one decoupling area facing the light forming optic unit, with the other optic unit being embodied as a widening optic unit for widening the partial light bundles emitted by the light sources with light guiding rods as optic elements.

Description

technical field [0001] The invention relates to a lighting device for a vehicle with a plurality of light sources arranged in a matrix in a light-generating area, with a light-shaping optical unit arranged in front of the light sources as seen in the main illumination direction of the light sources and with a light A further optical unit between the shaping optical unit and the light source, the further optical unit having a plurality of optical elements, wherein the optical elements are arranged in a matrix and each optical element is assigned with its end face to a light source , and wherein the further optical unit has, in the end-side region of the optical element, an incoupling surface corresponding to the light source and at least one outcoupling surface facing the light-shaping optical unit. Background technique [0002] Today more and more vehicle lighting devices are realized which provide one or more light distributions by means of a plurality of individual light s...
