LED module with a heat sink
An illuminating device includes: at least one lighting module, and at least one lighting module support, wherein the lighting module support is provided in order to dissipate heat from the lighting module and at least one first fastening element for fastening the lighting module on the lighting module support is provided, wherein the first fastening element is designed in such a way that the lighting module is pressed with a defined pressing force onto the lighting module support in such a way that a defined transfer of heat between the lighting module and lighting module support is enabled, and, in the region of the first fastening element, a movement of the lighting module, in particular a thermal expansion, parallel to the main plane of the lighting module is enabled.
1. An illuminating device-comprising:
at least one lighting module,
at least one lighting module support, wherein the lighting module support is provided in order to dissipate heat from the lighting module, and
at least one first fastening region comprising at least one first fastening element for fastening the lighting module on the lighting module support; wherein the at least one first fastening element comprises a u-shaped geometry having two branches extending from a bend therebetween; wherein each branch consists of a spring arm and contacts the bend;
at least one second fastening region for fastening at least one second fastening element on the lighting module and/or the lighting module support; and
at least one bridge connecting each spring arm of the at least one fastening element to the at least one second fastening element; wherein the at least one bridge comprises a wave-like shape between the at least one first fastening element and the at least one second fastening element.
2. The illuminating device as claimed in claim 1 , wherein the second fastening element comprises at least one screw and/or at least one rivet.
3. The illuminating device as claimed in claim 1 , wherein the first fastening element comprises at least one punched part.
4. The illuminating device as claimed in claim 3 , wherein the punched part is formed as a punched spring steel sheet.
5. The illuminating device as claimed in claim 1 , wherein the at least one bridge comprises, between the at least one first fastening region and the at least one second fastening region, at least one contact point for introducing force onto the lighting module and/or the lighting module support.
6. The illuminating device as claimed in claim 1 , wherein the at least one first fastening element comprises at least one fixing means for delimiting the movement of the lighting module.
7. The illuminating device as claimed in claim 1 , wherein the at least one first fastening element has a substantially frame-shaped geometry.
8. The illuminating device as claimed in claim 1 , wherein the movement of the lighting module is a thermal expansion.
