  • Patent number: 8009042
    Abstract: A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load.

  • Publication number: 20110163678
    Abstract: Light assemblies may contain a light socket assembly powered by an alternating current source, the light socket assembly containing a female socket for threadedly or otherwise receiving a light bulb or a retrofit socket, for example. An AC/DC converter electrically communicates with the light socket assembly thereby providing direct current to the light socket assembly. A first set of direct current contacts communicating with the AC/DC converter is formed within or about the light socket assembly. A solid state lighting source contains a second set of direct current contacts contained within the solid state lighting source, whereby the second set of direct contacts electrically communicates with and corresponds to the first set of direct current contacts. When assembled, the solid state lighting source such as an annular ring coupled to at least one light emitting diode, operably engages the light socket assembly and is fixed about at least a portion of the light socket assembly.

  • Publication number: 20110148309
    Abstract: A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the occupancy sensor provides additional information, such as information about movement detected in the monitored area, in the form of a signal superimposed on the occupancy signal, and a specialty power pack is configured to detect and respond to the superimposed information signal, thereby providing enhanced functionality to the lighting control system. The superimposed signal conveying the additional information is made high-speed/short-duration such that it is “invisible” to a conventional power pack and the occupancy sensor remains compatible with conventional power packs. The enhanced occupancy sensor may therefore be used seamlessly with both conventional and specialty power packs, and may be implemented as a “drop-in” component for legacy lighting control systems.

  • Patent number: 7965050
    Abstract: In an arrangement of lighting devices (10), a remote control device (30) and a central control device (20), a particular lighting device to be controlled by means of the remote control device may be selected by a user transmitting a selecting command (42, 43). When the central control device receives the selecting command (44), it carries out a selection sequence (45) during which it controls the lighting devices in one or the other sequence so as to have their output change temporarily (45, 46, 47). If the remote control device, which is directed to the particular lighting device (41), senses such an output change (50), it transmits data representing such an event (51) to the central control device. When the central control device receives such event data (52), it determines the particular lighting device as that to which the remote control device is directed (53) for subsequent control (54) of this particular lighting device.

  • Patent number: 7928670
    Abstract: An LED driver includes at least two interlocked closed feedback loops. One feedback loop controls the duty cycle of the on/off times of a switch connected in series to the LED string, and the other feedback loop controls the duty cycle of the on/off times of a power switch in the switching power converter that provides a DC voltage applied to the LED string. The LED driver of the present invention achieves fast control of the LED brightness and current sharing among multiple LED strings simultaneously in a power-efficient and cost-efficient manner.

    Abstract: A fluorescent lamp sensor system is provided. The fluorescent lamp sensor system includes a plurality of bulbs and a plurality of electrodes coupled to the bulbs. A balanced differential circuit measures changes in electric fields produced by the bulbs in front of the electrodes. The balanced differential circuit includes a symmetric current source associated with alternating the surface potential of the bulbs. A current mode detection circuit detects the current associated with the capacitive effects of the balanced differential circuit. A synchronous detection circuit isolates the capacitive effects of the symmetrical current source from stray signals that differ in either frequency or phase.
