Lighting System Pairing via Dynamic Transmission Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems require laborious pairing operations between luminaires and controllers, making the process inefficient, especially when dealing with multiple luminaires installed in large areas.
Innovation Solution
A lighting system with a wireless controller and a setting device that adjusts the transmission power of address request signals to ensure the total number of addresses received from luminaires falls within a target range, allowing for efficient pairing by adjusting the radio transmission power levels until the correct number of luminaires respond.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the setting device transmits address request signals at a fixed high transmission power level to ensure all luminaires are reached, then the coverage area is maximized, but the number of responding luminaires exceeds the target range making pairing laborious
Solution Approach 1:
The transmission power level is made dynamic rather than fixed. The setting device adjusts the transmission power level of address request signals based on the number of responding luminaires, transitioning between first transmission power level (when responses exceed target) and second transmission power level (when responses are within target), enabling adaptive control of the pairing process
Solution Approach 2:
The patent changes the transmission power parameter to control the number of responding luminaires. By varying the transmission power level between first and second levels, the system adjusts the coverage area to match the target number of luminaires, resolving the contradiction between maximizing coverage and maintaining manageable pairing operations
2Ease of operation
If the setting device transmits address request signals at a fixed low transmission power level to limit the number of responding luminaires, then the pairing operation is simplified, but the coverage area is reduced and some luminaires are missed
Solution Approach 1:
The transmission power level is dynamically adjusted based on real-time feedback from luminaire responses. Rather than using a fixed low power level that would consistently limit coverage, the system transitions between first and second transmission power levels to adaptively match the coverage area to the target number of luminaires, ensuring both complete coverage and manageable pairing
Solution Approach 2:
The setting device uses feedback from the number of address responses received to adjust transmission power level. When the number of responding luminaires exceeds the target, the device switches to second transmission power level; when within target, it uses first transmission power level, creating a closed-loop control system that resolves the contradiction between coverage and operational simplicity
3Device complexity
If the setting device uses a single transmission power level for all pairing operations, then the device complexity is reduced, but the productivity of pairing operations decreases due to manual intervention requirements
Solution Approach 1:
The setting device performs self-adjustment of transmission power level based on automatic counting of address responses. The control unit automatically determines when to switch between first and second transmission power levels without requiring manual intervention, enabling the system to serve itself and eliminating the need for complex manual power level management while maintaining high pairing productivity

AI summary
Luminaires in a lighting system have mutually different addresses. A setting device includes a communication unit that transmits an address request signal at a first transmission power level and a control unit that determines whether a total number of the addresses transmitted from one or more of the luminaires in response to receiving the address request signal is within a target range. The control unit instructs the communication unit to transmit the address request signal at a transmission power level different from the first transmission power level when the total number of the addresses is outside the target range, and executes pairing of the one or more of the luminaires that responded to the address request signal with a wireless controller when the total number of the addresses is within the target range.
