Abstract

The invention relates to a turn-indicator light module having an outer contour and comprising one or more light guiding elements and one or more visible-light emitting light sources coupled to at least one of the one or more light guiding elements, wherein at least one infrared light emitting light source is coupled to at least one of the one or more light guiding elements. At least a major portion of a longitudinal extension between a first end and a second end opposite of the first end of the one or more light guiding elements follows the outer contour and wherein the one or more light guiding elements are adapted to emit light at least along the major portion of their longitudinal extension.

Claims

1. A turn-indicator light module fixedly securable to an exterior rear view mirror of a motor vehicle wherein the exterior rear view mirror defines a forward facing contour, said turn-indicator light module comprising:

a single light guiding element defining a longitudinal extension and an outer contour, wherein said outer contour complementing the forward facing contour of the exterior rear view mirror;

a visible-light emitting source coupled to said single light guiding element such that visible light emitted by said visible-light emitting source is radiated out from said single light guiding element along all of said outer contour; and

an infrared light emitting source coupled to said single light guiding element such that infrared light emitted by said infrared light emitting source is radiated out from said single light guiding element along all of said outer contour in conjunction with and independently from the visible light being emitted by said visible-light emitting source, wherein the visible light and the infrared light are transmitted through said single light guiding element along said longitudinal extension thereof and are radiated out therefrom independently of each other.

2. The turn-indicator light module according to claim 1, wherein said infrared light emitting source and said visible-light emitting source are coupled to said single light guiding element.

3. The turn-indicator light module according to claim 1, wherein said single light guiding element to which said infrared light emitting source is coupled is arranged behind a light pane or in front of said light pane, and particularly arranged parallel to said light pane.

4. The turn-indicator light module according to claim 1, wherein said single light guiding element pierces through a light pane.

5. The turn-indicator light module according to claim 1, wherein said single light guiding element is integrated in a light pane.

6. The turn-indicator light module according to claim 3, wherein infrared light is coupled in said single light guiding element and said light pane.

7. The turn-indicator light module according to claim 1, wherein infrared light is coupled in an end of said single light guiding element.

8. The turn-indicator light module according to claim 1, wherein infrared light is coupled in at one end of said single light guiding element and visible light is coupled in said single light guiding element at a second end opposite said one end.

9. The turn-indicator light module according to claim 1, wherein said single light guiding element includes spatially separated structures for coupling out the visible light and the infrared light at spatially distinct locations along said single light guiding element.

10. The turn-indicator light module according to claim 9, wherein said single light guiding element includes light deflecting structures at a rear side thereof for deflecting visible light toward said plurality of spatially separated structures.
