  "claims": [
    "1. A device, comprising: a heat sink having a mounting surface for carrying a light source holding component and an opposed surface from which a plurality of radially oriented, heat dissipating fins extend; a junction box having a first wall formed by at least a portion of the opposed surface of the heat sink, a second wall formed in its entirety from a first surface of a first one of the plurality of heat dissipating fins, a third wall formed in its entirety from a first surface of a second one of the plurality of heat dissipating fins, a fourth wall that extends from the first surface of the first one of the plurality of heat dissipating fins to the first surface of the second one of the plurality of heat dissipating fins, and a fifth wall, opposite to and spaced from the fourth wall, that also extends from the first surface of the first one of the plurality of heat dissipating fins to the first surface of the second one of the plurality of heat dissipating fins; a gasket; and a junction box cover sized to cover the junction box, the junction box cover being removeably attachable to one or more of at least a second surface of the first one of the plurality of heat dissipating fins, a second surface of the second one of the plurality of heat dissipating fins, and the opposed walls; wherein the heat sink has at least one wire accepting aperture that extends between the mounting surface and the at least a portion of the opposed surface of the heat sink, each of the second surface of the first one of the plurality of heat dissipating fins, the second surface of the second one of the plurality of heat dissipating fins, and the opposed walls have a channel formed therein, and the gasket is positioned with the channels to thereby be interposed between the junction box cover and the second surface of the first one of the plurality of heat dissipating fins, the second surface of the second one of the plurality of heat dissipating fins, and the opposed walls.",
    "2. A device, comprising: a heat sink having a mounting surface for carrying a light source holding component and an opposed surface from which a plurality of radially oriented, heat dissipating fins extend; a junction box having a first wall formed by at least a portion of the opposed surface of the heat sink, a second wall formed in its entirety from a first surface of a first one of the plurality of heat dissipating fins, a third wall formed in its entirety from a first surface of a second one of the plurality of heat dissipating fins, a fourth wall that extends from the first surface of the first one of the plurality of heat dissipating fins to the first surface of the second one of the plurality of heat dissipating fins, and a fifth wall, opposite to and spaced from the fourth wall, that also extends from the first surface of the first one of the plurality of heat dissipating fins to the first surface of the second one of the plurality of heat dissipating fins; a junction box cover sized to cover the junction box, the junction box cover being removeably attachable to one or more of at least a second surface of the first one of the plurality of heat dissipating fins, a second surface of the second one of the plurality of heat dissipating fins, and the opposed walls; and a wire carrying cable coupled to the junction box cover via use of a water tight fitting; wherein the heat sink has at least one wire accepting aperture that extends between the mounting surface and the at least a portion of the opposed surface of the heat sink."

  "description_excerpt": "The present description relates generally to light source holding devices, and more particularly to a heat sink for use with a light source holding component\n\nAssemblies for holding a source of light, e.g., a LED light engine or a LED light module, are known in the art. By way of example, U.S. application Ser. No. 13/309,675, now published US patent application No. 2012/0305230, which is commonly assigned and which is incorporated herein by reference in its entirety, describes a light source holding component sized and arranged to securely receive a source of light. The light source holding component is intended to be attached to a mounting surface, such as a heat sink. In one described embodiment, the heat sink is provided with an integrated junction box to thereby reduce the part count of the device. An additionally described embodiment includes an accessory mounting feature. The accessory mounting feature is adapted to cooperate with an accessory to provide a seal against the mounting surface to which the light source holding component is attached.\n\nDescribed hereinafter is an improved heat sink for use in an assembly for holding a source of LED light. In one described embodiment, the subject heat sink is provided with a flexible conduit fitting that uses a screw or other piece of hardware to secure the flexible conduit to the heat sink. In this manner, wiring, e.g., Class 1 wiring used in connection with an LED light engine, may be enclosed by being passed through the heat sink and the flexible conduit attached thereto. In a second described embodiment, the heat sink is provided with a sealed, integrated junction box.",
