摘要： The present invention is directed to a lighting control system with a motion sensor unit that electrically couples to a load circuit through a latching relay or load controller for turning on and off lights. The motion sensor unit is configured to power down to draw zero power after a time delay, when motion is longer detected within the work space by the motion sensor unit. The lighting control system further includes a control circuit that reinitiates or turns the motion sensor back on through a switch device.

摘要： A scalable DC power distribution and control system suitable for commercial buildings includes one or more power and control hubs. Each DC power and control power hub provides power and control for any suitable distributed DC loads such as light-fixtures. AC power from the electric utility is applied to the power and control hub and is converted to DC power for distribution to DC loads within the space using low-voltage cables.

摘要： The adjustable voltage regulator under control of a microcontroller applies controlled amplitude voltage in the range of 5 to 9VDC to the sensor transmitter to adjust the output amplitude of the transmitter. The adjustable amplitude transmitter allows an occupancy sensor to have its total output energy adjusted to reduce environmental noise-induced false triggering and to conform to the area to be covered. Lowering the total ultrasonic energy in the monitored space lowers the sensitivity of the receiver to inappropriate activations. Lowering the input power to the transmitter also lowers the total internal system noise and provides an improved signal to noise ratio in the receiver.

摘要： Location-Based Addressing (LBA) is a method of controlling and commissioning networked lighting devices. The lighting devices communicate over a wireless network using radio frequency communication protocols. The lighting devices are commissioned or grouped based on their 5 respective locations in a building floor plan or a building architecture. The lighting devices are commissioned to respond to radio frequency communications that correspond to their respective locations. This imposed location-based architecture reduces the amount of transmitted data required to control the lighting devices and, thus, reduces the radio bandwidth required to control the lighting devices. In other words, controlling devices “multicast” instructions and controlled devices “listen” for instructions and act only upon instructions that correspond to their respective location. Hand shaking or two-way communication between the controlling devices and the controlled devices is not required.

摘要： A DC power supply for lighting includes low voltage driver electronics for any suitable load such as lighting along with a supervisory controller that communicates to the driver electronics via any suitable digital communication protocol. Each driver's output ports include a 3rd wire that communicates to the low voltage load fixture for the purpose of auto-negotiating the appropriate power level without first having to energize the fixture.

摘要： The methods and apparatus described enable automatic configuration, or commissioning, of controller devices and load control devices through a low voltage communication network controlled by one or more controller devices. These methods and apparatus further enable expansion of the load control system by connection of additional loads and or load control devices and or controller devices which will reinitialize the low voltage communication network and automatically reconfigure the controller devices and load control devices connected to the network.
