  • Patent number: 8206001
    Abstract: Methods and apparatus for providing sources of light, or mechanical and/or electrical connections for light sources, via a grid system of a suspended ceiling. All or a portion of a grid system for a suspended ceiling may be configured to support the generation of light. Lighting units may be coupled to various portions of the grid system in a removable and modular fashion, so as to be completely or substantially recessed above the ceiling surface, or as pendant components hanging below the ceiling surface. Lighting interface components of the grid system also may be configured to facilitate significant thermal dissipation from lighting units. In one exemplary implementation, one or more LED-based lighting units may be coupled to one or more lighting interface components of the grid system so as to provide controllable multi-color and/or essentially white light.

  • Patent number: 8134303
    Abstract: Methods and apparatus for simulating resistive loads, and facilitating series, parallel, and/or series-parallel connections of multiple loads to draw operating power. Current-to-voltage characteristics of loads are altered in a predetermined manner so as to facilitate a predictable and/or desirable behavior of multiple loads drawing power from a power source. Exemplary loads include LED-based light sources and LED-based lighting units. Altered current-to-voltage characteristics may cause a load to appear as a substantially linear or resistive element to the power source, at least over some operating range. In connections of multiple such loads, the voltage across each load is relatively more predictable. In one example, a series connection of multiple loads with altered current-to-voltage characteristics may be operated from a line voltage without requiring a transformer.

  • Patent number: 7781979
    Abstract: Methods and apparatus for controlling series-connected LEDs. Two or more LEDs are connected in series between a first node and a second node, wherein a series current flows between the nodes when an operating voltage is applied across the nodes. One or more controllable current paths are connected in parallel with at least a first LED for at least partially diverting the series current around at least the first LED. A controller monitors at least one parameter representative of the operating voltage, determines a maximum number of the series-connected LEDs that can be energized by the operating voltage, and controls the controllable current path(s) so as to increase an amount of the series current that is diverted around at least the first LED when the maximum number is less than a total number of all of the LEDs connected in series. In one example, the foregoing may be implemented as an integrated circuit package to provide a lighting apparatus suitable for automotive applications.

  • Patent number: 7777427
    Abstract: A controllable dimmer/relay used in combination with a power cycle control lighting device, wherein the controllable dimmer/relay serves as a network interface for the power cycle control lighting device. The controllable dimmer/relay is controlled by lighting commands formatted according to any of a variety of communications protocols, which instruct the controllable dimmer/relay to output one or more power cycles (interruptions in power) rather than gradual increases or decreases in power. In response to the power cycle(s) output by the controllable dimmer/relay, the power cycle control lighting device alters some aspect of the generated light (e.g., change one or more of color, color temperature, overall brightness, dynamic effect, etc.). In this manner, a power cycle control lighting device may be made responsive, via the controllable dimmer/relay, to lighting control commands formatted according to any of a variety of industry standard (e.g., DMX, Ethernet, DALI, X10) or proprietary protocols.

  • Patent number: 7737643
    Abstract: Methods and apparatus for providing and controlling power to loads including one or more LEDs. In one example, a controlled predetermined power is provided to a load without requiring any feedback information from the load (i.e., without monitoring a load voltage and/or load current). In another example, a “feed-forward” power driver for an LED-based light source combines the functionality of a DC-DC converter and a light source controller, and is configured to control the intensity of light generated by the light source based on modulating the average power delivered to the light source in a given time period, without monitoring and/or regulating the voltage or current provided to the light source. In various examples, significantly streamlined circuits having fewer components, higher overall power efficiencies, and smaller space requirements are realized.
