Socket and heat sink unit for use with removable LED light module

1. A socket and heat sink unit configured to couple to a removable LED light module, comprising:

a socket portion having one or more openings formed in a base thereof and one or more ramps aligned with said openings; and

a heat sink portion attached to the socket portion and extending about a longitudinal central axis of the heat sink, the heat sink portion comprising a plurality of fins defining channels aligned with said openings in the socket,

wherein the socket and heat sink portions are monolithic, and wherein the socket and heat sink can be formed in a die casting process comprising a die and cooperating slides, said slides positionable relative to the die to form the channels, openings and one or more edges of said ramps, the slides removable from the die when the die casting process is complete.

2. The unit of claim 1 , wherein the fins are defined by plate-like members axially aligned about the central axis so that the plate-like members extend generally perpendicular to the central axis.

3. The unit of claim 1 , wherein the fins extend radially outward from a central portion of the heat sink portion, each of the fins extending axially from the socket portion to a distal end of the heat sink portion.

4. The unit of claim 1 , further comprising one or more apertures are disposed on one or more of the fins and extend generally perpendicular to the central axis, the apertures configured to removably receive a fastener therein.

5. The unit of claim 1 , further comprising one or more apertures disposed on a distal face of the heat sink unit and extend generally parallel to the central axis, the apertures configured to removably receive a fastener therein.

6. The unit of claim 1 , further comprising an aperture in a wall of the socket portion.

7. The unit of claim 6 , further comprising an aperture in the base of the socket between a raised portion of the base and the wall of the socket.

8. A method of manufacturing a socket and heat sink unit, comprising:

providing a die having one or more complementary portions, said die having a shape complementary to the socket and heat sink unit;

positioning one or more slides in a desired position relative to the die; and

injecting molten metal under pressure into the die to die cast the socket and heat sink unit, the socket portion having one or more openings formed in a base thereof and one or more ramps aligned with said openings, the heat sink portion attached to the socket portion and extending about a central longitudinal axis of the heat sink, the heat sink portion comprising a plurality of fins defining channels aligned with said openings in the socket,

wherein the slides are positionable relative to the die to form the channels, openings and one or more edges of said ramps, the slides removable from the die when the die is detached from the socket and heat sink unit.

9. The method of claim 8 , wherein the die has five complementary portions.

10. The method of claim 8 , further comprising withdrawing the slides from the die before disassembling the die.

11. The method of claim 8 , wherein the slides comprise a proximal portion having a contour that defines the one or more edges of said ramps.

12. The method of claim 8 , wherein the slides are configured to extend through said openings in the base of the socket portion.
