  • Patent number: 9955541
    Abstract: Methods and apparatus relating to the collection of data regarding a plurality of customers in a retail or entertainment environment. Data may be collected via at least one sensor coupled to at least one lighting fixture in the retail or entertainment environment. In one exemplary implementation, data may be collected by one or more lighting fixtures, and data may be communicated via light generated by any one or more fixtures without perceivably affecting a quality of light generated by the one or more fixtures. A map may be generated based on the collected data to display traffic patterns and/or dwell times of the plurality of customers in the retail or entertainment environment, and such a map may be displayed, for example, via a graphical user interface.

  • 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.

    Abstract: Methods and apparatus for generating and modulating white light illumination conditions. Examples of applications in which such methods and apparatus may be implemented include retail environments (e.g., food, clothing, jewelry, paint, furniture, fabrics, etc.) or service environments (e.g., cosmetics, hair and beauty salons and spas, photography, etc.) where visible aspects of the products/services being offered are significant in attracting sales of the products/services. Other applications include theatre and cinema, medical and dental implementations, as well as vehicle-based (automotive) implementations. In another example, a personal grooming apparatus includes one or more light sources disposed in proximity to a mirror and configured to generate variable color light, including essentially white light, whose color temperature may be controlled by a user.

  • Publication number: 20110031888
    Abstract: A lighting apparatus (100) includes one or more first LEDs (202) for generating a first spectrum of radiation (503), and one or more second LEDs (204) for generating a second different spectrum radiation (505). The first and second LEDs are electrically connected in series between a first node (516A) and a second node (516B), between which a series current (550) flows with the application of an operating voltage (516) across the nodes. A controllable current path (518) is connected in parallel with one or both of the first and second LEDs so as to at least partially divert the series current, such that a first current (552) through the first LED(s) and a second current (554) through the second LED(s) are different. Such current diversion techniques may be employed to compensate for shifts in color or color temperature of generated light during thermal transients, due to different temperature-dependent current-to-flux relationships for different types of LEDs.

  • 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: 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.
