Abstract

The invention relates to a cooling device ( 10 ) for at least one light source ( 110 ) located in a lighting system ( 100 ) and having a cooling body ( 20 ), which comprises at least one contact surface ( 22 ) for absorbing heat from the at least one light source ( 110 ) and at least one cooling element ( 24 ) for emitting the absorbed heat, characterized in that the cooling body ( 20 ) has a mechanical interface ( 26 ) which is designed for an optional arrangement of counter-interfaces ( 66 ) of at least two different optical components ( 50 ).

First claim

The invention claimed is:

1. A cooling system comprising:
a cooling body, said cooling body comprising:
at least one light source;
at least one cooling element for emitting absorbed heat, the at least one cooling element projecting outwardly from the cooling body;
a contact surface opposing the at least one cooling element for absorbing heat from the at least one light source;
at least three external side portions each having an abutment surface, wherein each abutment surface includes a rib that protrudes outwardly from each abutment surface; and

at least a first optical component and a second optical component, each of said optical components comprising at least three internal side portions each having a second abutment surface, wherein each second abutment surface includes a groove that is recessed into each second abutment surface;
wherein the first and second optical components are installed on either: (i) the same vehicle at different locations, or (ii) on different vehicles; and
wherein a user may selectively install the cooling body into either the first or second optical component, wherein upon said installation, said grooves in the selected optical component receive and secure said ribs of the cooling body such that the cooling body is secured in the selected optical component.

2. The cooling system according to claim 1 , wherein the rib is tapered in a mounting direction in order to increase the guiding force between the abutment surface and the second abutment surface.

3. The cooling system according to claim 1 wherein the optical component includes an optical body that includes section-wise at least one of the following: a light-transmitting component, a total internal reflection body, a reflector, and a lens or lens system.

4. The cooling system according to claim 1 , wherein a circuit board is provided with the at least one light source, which is especially arranged in such a way that it is connected to a contact surface of a cooling body of the cooling device.
