Abstract

A device for fastening a fan in a housing of a lighting device, wherein the lighting device has a pot-shaped housing in which a number of lighting units are arranged, such that the fan can be fastened on a carrier frame at several fastening points by means of fasteners, wherein the carrier frame can be fastened on the housing by means of additional fasteners, wherein the fan is connected to the carrier frame at each fastening point by a plug-in connection as a fastener.

First claim

The invention claimed is:

1. A device for fastening a fan within a lighting device, comprising:
a pot-shaped housing of said lighting device in which a number of lighting units are arranged,
a retaining part of the housing on which the fan can be fastened at several fastening points by means of fasteners, wherein the fan is connected to the retaining part at each fastening point by a plug-in connection, and wherein the plug-in connection has a fastening pin and a flexible fastening socket, wherein the fastening pin can be inserted into the flexible fastening socket.

2. The device according to claim 1 , wherein the flexible fastening socket is set on an edge recess of the fan with a clamping effect.

3. The device according to claim 2 , wherein the flexible fastening socket has an annular groove that connects coaxial washer rings in the axial direction and that, in the installed position, the edge recess of the fan is inserted into the annular groove, wherein each washer ring contacts a flat side of the edge recess.

4. The device according to claim 2 , wherein the edge recess of the fan extends in an obtuse peripheral angle.

5. The device according to claim 2 , wherein the edge recess of the fan has a C-shaped edge, wherein a thickness of the C-shaped edge is greater than a width of the annular groove.

6. The device according to claim 1 , wherein, in a free end area of the fastening pin, a retaining cam projects laterally for engaging behind the flexible fastening socket set on the fastening pin.

7. The device according to claim 1 , wherein the flexible fastening socket is made from an elastic material.

8. The device according to claim 1 , wherein the retaining part is constructed as a carrier frame, wherein the carrier frame can be fastened on the housing by means of additional fasteners.

9. The device according to claim 1 , wherein the light unit has an LED light source that is allocated spatially to the fan.
