    摘要: Disclosed herein is system level occupancy counting in a lighting system configured to obtain an indicator data of a RF spectrum signal (signal) generated by a number of receivers at a number of times in an area. At each respective one of the number of times, for each respective one of the receivers, apply one of a plurality of heurist algorithm heuristic algorithm coefficients to each indicator data of the signal, based on results of the application of the heuristic algorithm coefficients, generate an indicator data metric value for each of the indicator data for the respective time. The lighting system is also configured to process each of the indicator data metric value to compute a plurality of metric values for the respective time and combine the plurality of metric values to compute an output metric value for each of a plurality of probable number of occupants in the area for the respective time. The lighting system is further configured to determine an occupancy count in the area at the respective time based on the computed output metric value.

    摘要: An intelligent lighting system may be installed using pre-existing electrical wiring, such as in a construction or retrofit environment. An intelligent lighting controller and an intelligent lighting fixture may be connected via electrical wiring that is configured for transmitting AC power signals. A commissioning signal may be transmitted to the intelligent lighting fixtures via the electrical wiring. In some cases, the intelligent lighting controller modifies portions of the AC power signal to indicate the commissioning signal. The intelligent lighting fixtures may receive the commissioning signal via the electrical wiring. In some cases, each intelligent lighting fixture that is connected to the electrical wiring, such as each intelligent lighting fixture on a lighting circuit in a room, receives the commissioning signal.

    摘要: An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.

    摘要: A system includes a control device and a plurality of lighting fixtures configured to receive power through the control device. Each lighting fixture includes a receiver and a memory, and is configured to: scan for a first message transmitted by the control device, the first message containing a unique identifier of the control device; receive the first message and store the unique identifier of the control device in the memory; sense a power interrupt to the lighting fixture initiated by the control device within a specified period of time after receipt of the first message from the control device; and transmit a second message including the unique identifier of the control device, the second message indicating that the lighting fixture is in a provisioning mode.

    摘要: A light fixture mounting assembly includes a surface mount, a lighting unit mount configured to engage the surface mount, and an arm connecting the surface mount to the lighting unit mount. The lighting unit mount is movable in use between a first configuration in which the lighting unit mount is disengaged from the surface mount and supported by the arm and a second configuration in which the lighting unit mount is engaged to the surface mount. Moving the lighting unit mount from the first configuration to the second configuration includes moving the lighting unit mount relative to the surface mount in a first direction to cause the surface mount and the lighting unit mount to draw closer together in a second direction that is nonparallel to the first direction.
