Abstract

A socket assembly is disclosed. The socket assembly includes a light emitting diode (LED) package having an LED printed circuit board (PCB), a base frame, an isolator frame, and an electrical contact. The base frame has a base mounted to a support structure and a spring finger extending from the base, the spring finger applying a clamping force to the LED PCB that acts in a direction toward the support structure. The isolator frame is mounted to the support structure. The electrical contact is electrically connected to the LED PCB and disposed within the isolator frame, such that the isolator frame electrically isolates the base frame from the electrical contact.

First claim

What is claimed is:

1. A socket assembly comprising:
a light emitting diode (LED) package having an LED printed circuit board (PCB) and a power pad disposed on the LED PCB;
a base frame having a base mounted to a support structure and a spring finger extending from the base, the spring finger directly contacting the LED PCB and configured to apply a clamping force to the LED PCB that acts in a direction toward the support structure;
an isolator frame mounted to the support structure; and
an electrical contact having an LED contact directly contacting and electrically connected to the power pad of the LED PCB, the electrical contact disposed within the isolator frame such that the isolator frame electrically isolates the base frame from the electrical contact, the isolator frame is disposed between the base frame and the electrical contact in a direction extending perpendicular to a plane defined by the LED PCB.

2. The socket assembly of claim 1 , further comprising a cover that extends over the base frame, the isolator frame, and the LED package, the cover having an opening that exposes an LED of the LED package.

3. The socket assembly of claim 1 , wherein the base frame is in thermal communication with the LED package.

4. The socket assembly of claim 1 , wherein a threaded fastener engages an anvil of the base frame and applies a clamping force to the base frame that acts in a direction toward the support structure.

5. The socket assembly of claim 1 , wherein the LED package is disposed within a recess of the base frame, the base frame having an LED mounting member contacting the LED PCB and holding the LED PCB within the recess.

6. The socket assembly of claim 1 , wherein the LED package is disposed within a recess of the base frame, and the isolator frame has an LED mounting member contacting the LED PCB and holding the LED PCB within the recess.

7. The socket assembly of claim 1 , wherein a retention feature of the isolator frame mechanically connects with a retention member of the base frame.

8. The socket assembly of claim 1 , further comprising a cover having an opening that exposes an LED of the LED package and a retention feature mechanically connecting with a retention member of the base frame.

9. The socket assembly of claim 1 , wherein the isolator frame has an isolator PCB electrically connected to the electrical contact, the LED PCB, and an electrical power supply.

10. The socket assembly of claim 1 , wherein a portion of the base frame is metal.

11. A socket assembly comprising:
a light emitting diode (LED) package having an LED printed circuit board (PCB) with an LED mounted thereto;
a metal base frame having a base mounted to a support structure and a spring finger extending from the base, the spring finger configured to apply a clamping force to the LED PCB that acts in a direction toward the support structure;
an isolator PCB electrically connected to an electrical power supply; and
an electrical contact electrically connected to the LED PCB and disposed within the isolator PCB such that the electrical contact electrically connects the isolator PCB to the LED PCB.

12. The socket assembly of claim 11 , further comprising an electrical connector electrically connected to the isolator PCB, the electrical connector being configured to be mated with a mating connector for supplying electrical power to the LED through the isolator PCB.

13. The socket assembly of claim 11 , wherein the base frame is in thermal communication with the LED package.

14. The socket assembly of claim 1 , wherein the isolator frame is disposed between a portion of the electrical contact and the LED PCB.

15. The socket assembly of claim 14 , wherein a side of the portion of the electrical contact is disposed directly on a surface of the isolator frame.

16. The socket assembly of claim 2 , wherein the cover overlaps an entirety of the base frame in a direction extending perpendicular to a plane defined by the LED PCB.

17. A socket assembly comprising:
a light emitting diode (LED) package having an LED printed circuit board (PCB) and a power pad disposed on the LED PCB;
a base frame having a base mounted to a support structure and a spring finger extending from the base, the spring finger directly contacting the LED PCB and configured to apply a clamping force to the LED PCB that acts in a direction toward the support structure;
an isolator frame mounted to the support structure; and
an electrical contact having an LED contact directly contacting and electrically connected to the power pad of the LED PCB, the electrical contact disposed within the isolator frame such that the isolator frame electrically isolates the base frame from the electrical contact, the isolator frame is disposed between a portion of the electrical contact and the LED PCB.

18. The socket assembly of claim 17 , wherein a side of the portion of the electrical contact is disposed directly on a surface of the isolator frame.

19. A socket assembly comprising:
a light emitting diode (LED) package having an LED printed circuit board (PCB) and a power pad disposed on the LED PCB;
a base frame having a base mounted to a support structure and a spring finger extending from the base, the spring finger directly contacting the LED PCB and configured to apply a clamping force to the LED PCB that acts in a direction toward the support structure;
an isolator frame mounted to the support structure and having an isolator PCB; and
an electrical contact having an LED contact directly contacting and electrically connected to the power pad of the LED PCB, the electrical contact disposed within the isolator frame such that the isolator frame electrically isolates the base frame from the electrical contact, the isolator PCB is electrically connected to the electrical contact, the LED PCB, and an electrical power supply.
