Abstract

A holder includes a socket. An insert can be positioned in the socket and includes two terminals configured to engage pads on an LED array. The insert and holder configuration can be configured to provide electrical isolation for a COB LED array so that additional flexibility in the selection of power suppliers is possible.

Claims

1. An insert, comprising:

a base with a mating pocket and a first projection and a second projection;

a first terminal insert-molded into the base and supported by the first projection, the first terminal providing a first contact extending from the first projection and a second contact extending into the mating pocket, the first terminal including a first body extending between the first contact and the second contact, the first body secured by the base; and

a second terminal insert-molded into the base, the second terminal providing a third contact extending from the second projection and a fourth contact in the mating pocket, the second terminal including a second body extending between the third and fourth contacts, the second body secured by the base.

2. The insert of claim 1, wherein the insert is configured to be inserted into a socket in a first direction and the first and third contacts are configured to engage contact pads that are arranged on a first plane that is substantially parallel to first direction.

3. The insert of claim 2, wherein the second and fourth contacts include a cross section that is substantially rectangular in shape and are arranged so that a longer side of the rectangular shape is substantially perpendicular to the first plane.

4. The insert of claim 2, wherein the second and fourth contacts and the pocket provide a mating interface that is configured to receive a mating connector, wherein in operation the mating connector is inserted into the pocket in a direction that is substantially perpendicular to the first plane.

5. A LED holder assembly, comprising:

a holder with a frame that includes an array recess configured to receive an LED array and secure it in position, the frame including an aperture and a socket that are both in communication with the array recess; and

an insert with a base configured to be mounted in the socket, the insert including a mating pocket and a first terminal supported by the base, the first terminal providing a first contact that extends into the array recess and a second contact that extends into the mating pocket, the first terminal including a first body extending between the first contact and the second contact, and the insert further including a second terminal supported by the base, the second terminal providing a third contact extending into the array recess and a fourth contact extending into the mating pocket, the second terminal including a second body extending between the second and fourth contacts.

6. The LED holder system of claim 5, wherein the insert includes a projection that is configured, in operation, to be positioned on top of an LED array, the projection having the first terminal extend therefrom and configured such that a distance from one the first terminal along a perimeter of the projection to an conductive surface of the LED array provides a predetermined voltage isolation

7. The LED holder system of claim 5, wherein the insert includes a first projection and a second projection that are configured, in operation, to be positioned on top of an LED array, the projections respectively having the first and second terminals extend therefrom and configured such that a distance from one of the terminals along a perimeter of the projection to an conductive surface of the LED array provides a predetermined voltage isolation.

8. The LED holder system of claim 7, wherein the distance is at least 2 mm.

9. The LED holder of claim 5, wherein the frame includes a terminal slot extending into the array recess, the terminal slot aligned with the first contact.

10. A LED holder assembly, comprising:

a frame with an array recess configured to receive an LED array and secure it in position, the frame including a socket;

an insert with a base configured to be mounted in the socket, the insert including a first terminal supported by the base and electrically connected to a first conductor that extends from the insert, the first terminal providing a first contact that extends into the array recess, the first terminal including a first body extending between the first contact and the conductor, and the insert further including a second terminal supported by the base and electrically connected to a second conductor, the second terminal providing a second contact extending into the array recess, the second terminal including a second body extending between the second contact and the second conductor.

11. The LED holder assembly of claim 10, wherein the first and second conductors are covered with an insulative layer.

12. The LED holder assembly of claim 10, wherein the frame includes a first terminal slot extending into the array recess that is aligned with the first contact and further includes a second terminal slot extending into the array recess that is aligned with the second contact.

13. The LED holder assembly of claim 10, wherein the array recess includes at least one crush rib.

14. The LED holder assembly of claim 10, wherein the frame includes a retention block configured, in operation, to support one edge of an LED array.

15. The LED holder assembly of claim 10, wherein the insert includes a first projection and a second projection that are configured, in operation, to be positioned on top of an LED array, the projections respectively having the first and second terminals extend therefrom and configured such that a distance from one of the terminals along a perimeter of the projection to an conductive surface of the LED array provides a predetermined voltage isolation.
