Abstract

A device for securing a source of LED light to a heat sink includes an LED light source engaging surface that is arranged and configured to engage at least a portion of the source of LED light and which is provided with an integrated force applying spring. Further, the device may include a continuous metallic path extending between the sources of LED light and the surface.

Claims

1. A device for releasably securing a LED light module, having one or more sources of LED light, on a mounting surface, comprising:

a monolithic member constructed from a resilient, metallic material having an aperture for the one or more sources of LED light wherein the aperture is completely surrounded by a planar LED light module engaging surface for releasable engagement with corresponding surfaces of the LED light module, the monolithic member further having at least a pair of fastener receiving openings each surrounded by a fastener engaging surface wherein an engagement between the fastener engaging surface and a corresponding fastener with the corresponding surfaces of the LED light module positioned in engagement with the planar LED light module engaging surface places the planar LED light module engaging surface under load such that the planar LED light module engaging surface applies a generally uniform force upon the corresponding surface of the LED light module to secure the LED light module on the mounting surface while providing at least one continuous metallic path between the mounting surface and the LED light module.

2. A device as recited in claim 1, wherein the at least a pair of fastener receiving openings are each keyhole shaped to allow a fastener head of the at least one or more metal fasteners to pass only through a larger part of each of the at least a pair of fastener receiving openings.

3. A device as recited in claim 1, wherein the device is arranged to be releasably lockable in an installed position in which the LED light module is secured to the mounting surface.

4. A device as recited in claim 3, wherein the device is adapted to be slid in a generally parallel direction relative to the mounting surface to transition the device from a free position to the installed position.

5. A device as recited in claim 3, wherein the device is adapted to be rotated in a plane parallel to the mounting surface to transition the device from a free position to the installed position.

6. A device as recited in claim 1, further comprising a set of deflectable arms coupled to the monolithic member for grasping an accessory attachable to the device.

7. A device as recited in claim 1, further comprising at least one electrically insulating housing carried by the monolithic member, the at least one electrically insulating housing having an electrical contact element disposed therein, the electrical contact element being arranged to electrically coupled to a correspond electrical contact of the LED light module and to remain electrically insulated from monolithic member.

8. A device as recited in claim 7, wherein the at least one electrically insulating housing is attached to a side of the monolithic member that is closer to the mounting surface.

9. A device as recited in claim 7, wherein the electrical contact element comprises one or more portions that are generally biased to engage the corresponding electrical contact of the LED light module.

10. A device as recited in claim 7, wherein the electrical contact element is connected to one or more wires.

11. A device as recited in claim 10, wherein the electrical contact element comprises at least one push-in type connector for engaging the one or more wires.

12. A device as recited in claim 10, wherein the device further comprises one or more routing elements for positioning the one or more wires through a path.

13. A device as recited in claim 1, further comprising one or more locating features associated with the monolithic member co-operable with a feature of the LED light module for use in locating the LED light module in engagement with the LED light module engaging surface.

14. A device as recited in claim 13, wherein at least one of the one or more locating features is deflected when the LED light module is placed into engagement with the LED light module engaging surface.

15. A device as recited in claim 13, wherein the one or more locating features holds and secures the LED light module to the monolithic element prior to attachment of the device to the mounting surface.

16. A device as recited in claim 1, further comprising one or more rib-like elements provided to a surface of the monolithic structure opposite the LED light module engaging surface to stiffen part of the device.

17. A device as recited in claim 1, wherein the at least a pair of fastener receiving openings are disposed on opposed sides of the aperture.
