Wireless Lighting Controller Grouping by Transmission Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless lighting control systems consume excessive power by using strong transmission power to communicate with luminaires, even when a weaker signal would suffice, leading to increased power consumption.
Innovation Solution
A wireless controller classifies luminaires into groups based on their communication power requirements, using first transmission power for those that respond and second transmission power for those that do not, thereby optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strong transmission power is used to ensure communication with all luminaires, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by classifying luminaires into different groups based on their distance and communication characteristics from the wireless controller. Each group is assigned appropriate transmission power levels tailored to its specific communication needs, rather than using uniform high power for all luminaires. This resolves the contradiction by providing high transmission power only where necessary (for distant or difficult-to-reach luminaires) while using lower power for nearby luminaires, thus maintaining communication reliability while reducing overall power consumption.
2Area of stationary object
If uniform transmission power is used for all luminaires, then communication coverage is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent implements segmentation by dividing the plurality of luminaires into multiple groups based on their communication characteristics and distance from the wireless controller. Each group is assigned a specific transmission power level appropriate for its characteristics. This segmentation approach ensures that all luminaires receive adequate communication coverage while avoiding the energy waste of applying uniform high transmission power to all devices, thereby resolving the contradiction between communication coverage and energy efficiency.
3Length of stationary object
If transmission power is increased to reach distant luminaires, then communication range is improved, but power consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the transmission power parameter based on the distance and communication characteristics of each luminaire group. Instead of using a fixed high transmission power level, the system varies the power parameter according to the specific communication needs of each group, enabling extended communication range for distant luminaires while minimizing power consumption by using lower power for nearby luminaires.

AI summary
A lighting system includes a wireless controller, luminaires each configured to communicating with the wireless controller, and a storage. The wireless controller classifies a first luminaire among the luminaires, which is able to communicate using first transmission power, into a first group and stores the first luminaire on the storage, and classifies a second luminaire among the luminaires, which is able to communicate using second transmission power greater than the first transmission power, into a second group and stores the second luminaire on the storage.
