Modular coordinated lighting system
摘要
說明書
In embodiments a wireless lighting module or device may be comprised of a light source, a receiver configured to receive a lighting action command directing the wireless lighting module to respond to the detected change in electric power, a power source configured to provide power to the light source, a controller configured to control the power source in response to the lighting action command and a housing including the light source, the receiver and the power source. In embodiments of the wireless power outage lighting system, the wireless transmitter of a first power change detection apparatus avoids interference with the transmission of a second power change detection apparatus by transmitting at a first time delay from a detected change in electric power and the second power change detection apparatus avoids interference with the transmission of the first power change detection apparatus by transmitting at a second time delay from a detected change in electric power. The power change detection apparatuses may use a time delay that is set by assigning a channel number to a power change detection apparatus corresponding to the delay in time of the transmission from the detected change in power. The power change detection apparatuses may have the channel number assigned by at least one of a dip switch, a device programming method or factory configuration. In embodiments, the power change detection apparatuses may transmit the channel number as part of the lighting action command. In embodiments of the wireless power outage lighting system, the wireless transmitter of a first power change detection apparatus avoids interference with the transmission of a second power change detection apparatus by transmitting at a different frequency. In embodiments, the wireless power outage lighting system may have a first group of one or more wireless lighting modules configured to respond to the channel number assigned to a first power change detection apparatus and a second group of one or more wireless lighting modules configured to respond to the channel number assigned to a second power change detection apparatus.
