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 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.

Claims

1. A system for controlling one or more devices to be controlled using location-based addressing, the system comprising:

a first device configured to transmit a control signal containing a function code and a location based address corresponding to a location;

one or more devices to be controlled which are configured to receive the control signal, wherein each of the one or more devices is configured to be programmable with a location descriptor corresponding to at least one location; and

wherein each of the one or more devices to be controlled is configured to be programmable to compare the transmitted location based address to the location descriptor and perform a function corresponding to the function code in response to a match between the location-based address and the programmed location descriptor.

2. The system of claim 1, wherein the location based address includes a hierarchical data structure comprising data fields corresponding to one or more of a building, a house, a floor, a room and one or more portions of a room.

3. The method of claim 1 wherein the location based address is generated by concatenating a unique physical address onto a root location based address.

4. The system of claim 1, wherein the one or more devices to be controlled are selected from the group consisting of a light fixture, a fan, an electrical heater, a motion detector, an electrical outlet or an air conditioning and heating unit.

5. The system of claim 1, further comprising:

a playback device configured to store location-based addresses and function codes corresponding to a sequence of transmitted control signals over a selected time period as an program;

wherein the playback device is programmed to transmit the program to the one or more devices to be controlled at a selected time.
