Solution Overview
Problem
Conventional LED lighting systems lack the ability to operate independently of wired power sources, limiting their installation flexibility and efficiency, especially during power outages, and do not effectively manage energy consumption to address peak demand and cost concerns.
Innovation Solution
The integration of wireless control and power systems in LED lighting devices, allowing them to operate autonomously with internal power sources, such as rechargeable batteries, and communicate through networks for coordinated power management, enabling installation without wired connections and efficient energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lighting systems use wired power connections, then power supply stability is improved, but installation flexibility and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired power connection system with a wireless power transmission system using electromagnetic fields. The lighting device receives power wirelessly through a power receiver that converts electromagnetic energy to electrical energy, eliminating the need for physical power cables while maintaining reliable power supply.
Solution Approach 2:
The patent introduces a wireless power transmission intermediary system consisting of a power transmitter and power receiver. The transmitter converts electrical energy to electromagnetic energy, which is then received and converted back to electrical energy by the receiver, serving as an intermediary medium to transfer power without direct physical connection.
2Ease of operation
If LED lighting systems use internal power sources for wireless operation, then installation flexibility is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic wireless power transmission where the power transmitter sends power in scheduled intervals or on-demand basis. The system can transmit power during off-peak hours or when lighting is not immediately needed, allowing the internal battery to charge gradually rather than requiring large capacity for continuous operation.
Solution Approach 2:
The patent uses a hybrid power system that dynamically switches between wireless power reception and internal battery power. The system can adaptively choose the power source based on availability, demand, and battery charge level, optimizing energy consumption while maintaining installation flexibility.
3Reliability
If multiple lighting devices operate independently during power outages, then reliability is improved, but coordinated power management and energy efficiency deteriorate
Solution Approach 1:
The patent implements a feedback-based power management system where the central controller receives status information from multiple lighting devices and sends coordinated control commands. The system monitors power availability, battery charge levels, and lighting demands to optimize power distribution and minimize energy consumption during peak demand periods.
Solution Approach 2:
The patent creates a universal wireless power management network that can operate in multiple modes: coordinated group operation for energy efficiency, independent operation for reliability during outages, and hybrid modes. The system adapts its behavior based on environmental conditions and power availability, providing multi-functional power management.

AI summary
Aspects of the presently disclosed embodiments may include a wireless power outage lighting system comprising one or more power change detection apparatuses and one or more wireless lighting modules where the system is implemented to allow management of multiple groups in the same area such that interference may be avoided when there are multiple transmissions in the same area. A power change detection apparatus may be configured to transmit to avoid interference with another power change detection apparatus. A power change detection apparatus may also be configured through the user input method to operate different groups of wireless lighting modules such that lighting zones may be created. Multiple lighting zone allow a user to configure lighting provided by the wireless power outage lighting system based on their preference.
