Abstract

An energy consumption device includes a housing that supports a first and second terminal. An energy consuming module, which may include a light emitting diode array, is supported by the housing and is thermally coupled to a thermal bridge that extends below a lower surface of the housing. A cover can be positioned so as to secure the energy consuming module between the cover and the housing. A plurality of magnets can be configured to secure the energy consumption device to a rail that supports powered contacts so that the first and second terminals engage the powered contacts and the thermal bridge is pressed against the rail.

Claims

1. A LED assembly, comprising:

a housing having a top surface with an aperture positioned centrally in the housing, the housing including a first trace that extends from a first electrical opening in the housing, the first electrical opening extending from the top surface through the housing, the first electrical opening positioned adjacent the aperture, the housing further including a second trace that extends from a second electrical opening in the housing, the second electrical opening extending from the top surface through the housing, the second electrical opening positioned adjacent the aperture, wherein the traces respectively extend into the first and second electrical openings; and

a LED array including a base that supports at light emitting area on a top surface, the light emitting area extending above the base, the base having an anode pad and a cathode pad positioned on the top surface, wherein the aperture is configured to align with the LED array such that the anode pad and cathode pad are aligned with the first and second electrical openings and light emitting area extends through the aperture, the first and second traces being respectively electrically connected to the anode and cathode pads.

2. The LED assembly of claim 1, wherein the electrical openings are tapered.

3. The LED assembly of claim 1, wherein the aperture includes at least one orientation feature that extends into the aperture so as to control orientation of the LED array with respect to the housing.

4. The LED assembly of claim 1, wherein the first and second electrical openings are on opposite sides of the aperture.

5. The LED assembly of claim 1, wherein the base of the LED array extends below a bottom surface of the housing.
