Abstract

A socket assembly includes a light emitting diode (LED) package having an LED printed circuit board (PCB) with an LED mounted thereto. The socket assembly also includes a clamp for holding the LED package to a support structure. The clamp includes a base that is configured to be mounted to the support structure such that the base engages the support structure. The clamp also includes a spring finger that extends from the base such that the base and the spring finger define a unitary body of the clamp. The spring finger is configured to engage the LED PCB of the LED package and apply a clamping force to the LED PCB that acts in a direction toward the support structure.

Claims

1. A socket assembly comprising:

a light emitting diode (LED) package having an LED printed circuit board (PCB) with an LED mounted thereto; and

a clamp for holding the LED package to a support structure, the clamp comprising a base that is configured to be mounted to the support structure such that the base engages the support structure, the clamp further comprising a spring finger that extends from the base such that the base and the spring finger define a unitary body of the clamp, the spring finger being configured to engage the LED PCB of the LED package and apply a clamping force to the LED PCB that acts in a direction toward the support structure, wherein the clamp comprises a mounting member that is configured to cooperate with a mounting feature of the support structure with at least one of a snap-fit connection or an interference-fit connection to mount the base of the clamp to the support structure.

2. The socket assembly of claim 1, wherein the spring finger is integrally formed with the base to define the unitary body of the clamp.

3. The socket assembly of claim 1, wherein the unitary body of the clamp is metallic.

4. The socket assembly of claim 1, wherein the unitary body of the clamp is a cut and formed unitary body.

5. The socket assembly of claim 1, wherein the unitary body of the clamp comprises a recess that receives the LED package therein.

6. The socket assembly of claim 1, wherein the base comprises a ring structure having a central axis, the ring structure of the base being configured to extend at least partially around a circumference of the LED PCB, the spring finger extending from the ring structure of the base in a radially inward direction relative to the central axis.

7. The socket assembly of claim 1, wherein the clamp comprises a retention member that is configured to cooperate with a retention member of a housing such that the clamp is mechanically connected to the housing.

8. The socket assembly of claim 1, wherein the base comprises a ring structure having a central axis, the ring structure of the base being configured to extend at least partially around a circumference of the LED PCB, the clamp further comprising a locating member that extends from the ring structure of the base in a radially inward direction relative to the central axis, the locating member being configured to engage the LED PCB to locate the LED package relative to the clamp.

9. The socket assembly of claim 1, wherein the LED PCB comprises a substrate that includes a ceramic substrate.

10. A socket assembly for light emitting diode (LED) packages having an LED printed circuit board (PCB), the socket assembly comprising:

a housing having a recess that is configured to receive an LED package therein, the housing being configured to be mounted to a support structure; and

a clamp comprising a base that is configured to be mounted to the support structure such that the base engages the support structure, the clamp further comprising a spring finger that extends from the base, the spring finger being configured to engage the LED PCB of the LED package and apply a clamping force to the LED PCB that acts in a direction toward the support structure to clamp the LED PCB between the spring finger and the support structure independent of the housing being mounted to the support structure.

11. The socket assembly of claim 10, wherein the base of the clamp comprises a ring structure having a central axis, the ring structure of the base being configured to extend at least partially around a circumference of the LED PCB, the spring finger extending from the ring structure of the base in a radially inward direction relative to the central axis.

12. The socket assembly of claim 10, wherein the clamp comprises a mounting member that is configured to cooperate with a mounting feature of the support structure to mount the base of the clamp to the support structure.

13. The socket assembly of claim 10, wherein the clamp is mechanically connected to the housing.

14. The socket assembly of claim 10, wherein the spring finger extends from the base such that the base and the spring finger define a unitary body of the clamp.

15. The socket assembly of claim 10, wherein the spring finger is integrally formed with the base.

16. The socket assembly of claim 10, wherein the base and the spring finger define a body of the clamp, the body of the clamp being metallic.

17. The socket assembly of claim 10, wherein the clamp and the housing comprise mounting members that are aligned with each other for cooperating with a common mounting feature of the support structure to mount the clamp and the housing to the support structure.

18. A lighting assembly comprising:

a support structure having a mounting surface; and

a socket assembly comprising;

a light emitting diode (LED) package having an LED printed circuit board (PCB) with an LED mounted thereto;

a clamp for holding the LED package to the support structure, the clamp having a base that is configured to be mounted to the support structure such that the base is engaged with the mounting surface of the support structure, the clamp further comprising a spring finger that extends from the base such that the base and the spring finger define a unitary body of the clamp, the spring finger being configured to engage the LED PCB of the LED package and apply a clamping force to the LED PCB that acts in a direction toward the mounting surface of the support structure; and

a housing having a recess that is configured to receive the LED package therein, the housing being configured to be mounted to the support structure.
