Wireless Lighting Control Device Low Power Battery Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery-powered wireless lighting control devices face challenges in conserving battery power during installation and commissioning, with existing methods being error-prone, labor-intensive, and wasteful of battery life, as they require physical disconnection or insertion of batteries, which can lead to operational issues and increased costs.
Innovation Solution
Implementing a low power mode in battery-powered wireless lighting control devices that remain in a deep sleep state until activated by a user stimulus, such as a button press or motion detection, allowing for temporary power-up during commissioning and reducing the need for physical battery installation or pull tabs, thereby conserving battery life and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If batteries are physically disconnected using pull-tabs or not included during manufacturing, then battery power is conserved during storage and transport, but installation complexity increases and user error becomes more likely
Solution Approach 1:
The device is pre-configured with batteries during manufacturing and enters a deep sleep mode automatically. This preliminary action eliminates the need for users to install batteries or remove pull-tabs, while the deep sleep mode ensures minimal power consumption during storage and transport, resolving both the energy conservation and installation ease requirements
2Loss of energy
If the device remains in deep sleep mode until commissioning, then battery power is conserved, but the device cannot perform commissioning functions without waking up
Solution Approach 1:
The device dynamically transitions between deep sleep mode and active commissioning mode based on detected user stimuli. Motion sensors, light sensors, or button presses trigger the transition from low-power deep sleep state to full operational state, enabling commissioning functions only when needed while conserving battery power during storage and transport
3Adaptability or versatility
If the device wakes up for commissioning, then commissioning functions can be performed, but battery power is consumed during the wake state
Solution Approach 1:
The device employs periodic action by waking up temporarily in response to detected stimuli, performing necessary commissioning functions, and then returning to deep sleep mode. This periodic activation ensures that the device only consumes battery power when commissioning is actually needed, rather than remaining continuously active
Solution Approach 2:
The device uses environmental cues such as motion detection, light detection, or button presses to automatically trigger wake-up for commissioning. This self-service mechanism eliminates the need for continuous power consumption or manual intervention, allowing the device to autonomously determine when commissioning is required

AI summary
The wireless lighting control device examples conserve battery power before installation and/or commissioning. To save battery life, such a device remains in a low power mode and is awakened for commissioning, for example, by a button press (e.g. for a wall switch) or motion or audio sensing (e.g. for an occupancy sensor or the like). When awakened, the lighting control device enters its commissioning mode with the radio transceiver active for a short period of time. If the lighting control device is not commissioned within that time interval, for example, it may reenter the sleep mode. Conversely, if successfully commissioned during the active time period, the lighting control device is ready for normal operations.
