  • Publication number: 20080164827
    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.

  • Publication number: 20080012506
    Abstract: Apparatus and systems including one or more first LEDs, each first LED configured to generate first radiation having a first spectrum, and one or more second LEDs, each second LED configured to generate second radiation having a second spectrum different than the first spectrum. A diffuser is employed to blend the first radiation and the second radiation, when generated, so as to provide a uniform color of light having a visible spectrum based on a combination of the first spectrum and the second spectrum. One or more controllers are configured to control the first LED(s) and the second LED(s) such that visible light provided by the diffuser is perceived as one or more colors. In different aspects, the apparatus/systems may be configured to generate white light and/or multicolor light, may be formed to resemble conventional light bulbs, and may be arranged as a linear chain of nodes.

  • Publication number: 20080012502
    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.

  • Publication number: 20070237284
    Abstract: Methods and apparatus for computer-based control of light sources in a networked lighting system. In one example, a plurality of LED-based lighting systems are arranged as computer controllable “light strings.” Applications contemplated for such light strings include, but are not limited to, decorative and entertainment-oriented lighting applications (e.g., Christmas tree lights, display lights, theme park lighting, video and other game arcade lighting, etc.). Via computer control, one or more such light strings may provide a variety of complex temporal and color-changing lighting effects. In one example, lighting data is communicated in a given light string in a serial manner, according to a variety of different data transmission and processing schemes. In another example, individual lighting systems of a light string are coupled together via a variety of different conduit configurations to provide for easy coupling and arrangement of multiple light sources constituting the light string.

In another example, a first intensity of the first radiation and a second intensity of the second radiation are independently controlled so as to controllably vary at least an overall perceivable color of generated visible radiation. In yet another example, a first control signal controls all of the first light sources substantially identically, and a second control signal controls all of the second light sources substantially identically.

  • Publication number: 20070188114
    Abstract: Methods and apparatus for high power factor power transfer to a load using a single switching stage. In exemplary implementations, a controllable variable power may be delivered to a load using a single switching stage while maintaining high power factor, in some cases without requiring any feedback information relating to the load conditions (i.e., without monitoring load voltage and/or current) to control normal switching operations in the single switching stage, and without requiring regulation of load voltage and/or load current. In one example, a single stage high power factor driver is used to control power delivery to an LED-based light source.
