Location-Based Addressing for Wireless Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting and environmental control systems face challenges in scalability, maintenance, and automation due to the need for individual device addressing and complex control processes, which hinder efficient remote control of multiple devices in a room.
Innovation Solution
The implementation of location-based addressing, where devices are commissioned into sets based on physical locations, allowing control signals with location descriptors to manage multiple devices with a single command, reducing bandwidth and complexity through anonymous multicast signals and hierarchical addressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual device addressing is used to control each device separately, then device control precision is improved, but system complexity and time consumption increase significantly when controlling multiple devices
Solution Approach 1:
The patent segments the addressing system into two levels: individual device addresses for precise identification and location-based group addresses for collective control. Devices are assigned both unique individual addresses and location-based addresses that group them by physical location, enabling both individual and collective control without conflict.
Solution Approach 2:
The patent adds a spatial dimension to the addressing system by introducing location-based addressing. Instead of only using individual device addresses, the system incorporates location information (such as room or area identifiers) as an additional addressing dimension, allowing devices to be controlled based on their physical location rather than individual addresses.
2Measurement precision
If individual device addressing is used for each device, then device identification accuracy is improved, but the time required to control multiple devices increases
Solution Approach 1:
The patent merges individual device control with location-based group control. By combining individual addresses with location-based addresses, the system enables simultaneous control of multiple devices within a location through a single command, eliminating the need to send separate commands to each device individually.
Solution Approach 2:
The patent adds a spatial dimension to the addressing system by introducing location-based addressing. Instead of only using individual device addresses, the system incorporates location information (such as room or area identifiers) as an additional addressing dimension, allowing devices to be controlled based on their physical location rather than individual addresses.
3Ease of operation
If traditional addressing systems are used, then device control capability is maintained, but scalability and ease of maintenance deteriorate when devices are replaced or added
Solution Approach 1:
The patent segments the addressing system into two independent levels: individual device addresses and location-based addresses. This segmentation allows the system to maintain device control capability through individual addresses while simultaneously achieving scalability through location-based addresses that remain valid even when devices are replaced or added within the same location.
Solution Approach 2:
The patent creates a universal addressing system that serves multiple functions: individual device identification, location-based grouping, and automatic device discovery. The location-based addresses act as universal identifiers for groups of devices at specific locations, enabling the system to adapt to changes in device composition without requiring reconfiguration of control logic.

AI summary
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.
