  • Patent number: 9320093
    Abstract: The disclosure is directed at a method and apparatus for configuring and powering light fixture loads for a LED low voltage distribution system. The method and apparatus include converting power being supplied for powering the set of light fixture loads and then limiting this converted power to a set of multiple current outputs supplied to the light fixture loads. The multiple current outputs are then split or regrouped prior to being delivered to the light fixture loads.
    Type: Grant
    Filed: January 6, 2015
    Date of Patent: April 19, 2016
    Assignee: LUMASTREAM CANADA ULC

  • Patent number: 8957601
    Abstract: The disclosure is directed at a configurable light emitting diode (LED) dimmer for controlling a set of light fixture loads comprising: a power circuit; a primary digital controller for controlling the power circuit; a set of output current drivers, each of the set of output current drivers connected to one of the set of light fixture loads for controlling the associated light fixture load; a secondary digital controller for controlling the set of output current drivers; wherein the secondary controller transmits LED control information to control outputs of the set of output current drivers; and wherein the secondary digital controller provides digital feedback control information to the primary digital controller.

  • Patent number: 8926133
    Abstract: A lighting system includes a base that is made of a thermally conductive material. Mounted within a cavity in the base and thermally interfaced to the base is a device that produces light (LED or LED array). Heat produced by the device that produces light conducts from the device to the base. A removable bezel is connected to the base along a conical frustum interface. The interface is formed at an angle with respect to a lengthwise axis of the bezel such that heat from the base conducts through the conical frustum interface and to the bezel from which the heat is radiated into the room ambient environment. An extension of the bezel includes an optional trim preferably made of the same or a similar material.
