Optic Coupler for Light Emitting Diode Fixture
A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

11 . The recessed light fixture of claim 10 , wherein the optic coupler further comprises:
a bottom member defining the second opening;
a side member extending angularly from the bottom member; and
an engaging member extending angularly from the side member,
wherein the side member is disposed substantially between the bottom member and the engaging member, and wherein the engaging member comprises the engaging surface.
12 . The recessed light fixture of claim 11 , wherein the engaging member is substantially parallel to the bottom member.
13 . The recessed light fixture of claim 1 , wherein the LEDs are configured in an array having a first shape, and wherein a shape of the first opening is substantially the same as the first shape.
14 . The recessed light fixture of claim 13 , wherein the second opening has a shape that is substantially the same as the shape of the first opening.
15 . A recessed light fixture, comprising:
a light emitting diode (“LED”) package comprising at least one LED;
a reflector housing;
a reflector disposed substantially within the reflector housing, around at least a portion of the LED package; and
an optic coupler disposed substantially between the LED package and the reflector, the optic coupler comprising an engaging surface that engages a top end of the reflector such that the top end of the reflector is disposed between a side edge of the optic coupler and an inside surface of the reflector housing.
16 . The recessed light fixture of claim 15 , wherein the LED package generates substantially all light emitted by the recessed light fixture.
17 . The recessed light fixture of claim 15 , wherein the optic coupler further comprises:
a top member defining a first opening;
a bottom member defining a second opening; and
at least one wall member extending between the top member and the bottom member and defining a channel that connects the first opening and the second opening,
wherein the channel is substantially aligned with the LEDs so that the LEDs are visible through the channel.
18 . The recessed light fixture of claim 17 , wherein the optic coupler further comprises:
a side member extending angularly from the bottom member; and
an engaging member extending angularly from the side member,
wherein the side member is disposed substantially between the bottom member and the engaging member, and wherein the engaging member comprises the engaging surface.
19 . The recessed light fixture of claim 18 , wherein the engaging member is substantially parallel to the bottom member.
20 . The recessed light fixture of claim 18 , further comprising at least one electrical connection electrically coupled to the LED package and configured to provide power thereto,
wherein the bottom member and the side member define a region that at least partially houses the at least one electrical connection.
21 . The recessed light fixture of claim 20 , wherein the at least one electrical connection are not visible when looking into the recessed light fixture from an environment illuminated by the recessed light fixture.
22 . A recessed light fixture, comprising:
a light emitting diode (“LED”) package comprising at least one LED;
a reflector disposed around at least a portion of the LED package; and
an optic coupler disposed substantially between the LED package and the reflector and covering at least one electrical connection on the LED package, the optic coupler comprising an aperture through which light emitted by the LEDs is visible.
