Abstract: 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 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.

Abstract: A lighting control system comprising: at least two luminaires (12), a control unit (14) coupled to the at least two luminaires (12) by a communication link (16), by which control unit a respective illuminance of the at least two luminaires (12) can be varied, and comprising at least two sensors (18). Each of the at least two luminaires (12) is assigned at least one sensor (18). The at least two sensors (18) have a first sensitivity at which a first signal can be generated as a result of the sensor (18) being acted upon by a first parameter detectable by the sensor (18), and the respective illuminance can be set in a manner dependent on said first signal. Each of the at least two sensors (18) is adapted to generate an address, wherein the generated address of the respectively addressed sensor can be determined by the control unit (14).
