Battery LED Bulb with Edison Socket Charging Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light bulbs require either AC to DC converters within the bulb or battery-powered solutions that are not compatible with conventional Edison socket infrastructure, making it difficult to use them in existing light fixtures without extensive electrical modifications.
Innovation Solution
A battery-operated LED light assembly with a housing that includes a bulb-shaped upper end and a nonconductive threaded lower end, featuring a charging port, a battery enclosure, and two PCB boards for power and control circuits, allowing the LED light to be used in conventional Edison sockets without drawing current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED lights use AC to DC converters within the bulb, then they can be used in conventional AC sockets, but the bulb structure becomes incompatible with conventional Edison socket form factor
Solution Approach 1:
The invention divides the lighting system into two separate components: a battery-powered LED bulb that maintains conventional Edison socket form factor, and a separate AC to DC converter unit that plugs into the same socket. This segmentation allows the bulb to retain its simple, compatible structure while the converter handles the power conversion function externally.
Solution Approach 2:
The invention introduces a charging cradle or converter unit as an intermediary device that sits between the AC power source and the LED bulb. This intermediary performs the AC to DC conversion and charges the battery in the bulb, allowing the bulb itself to remain a simple, socket-compatible form factor without integrated power conversion circuitry.
2Ease of operation
If battery-powered LED bulbs are used, then they can operate without AC power, but they require non-Edison socket form factors and adhesive or mechanical fastening
Solution Approach 1:
The invention creates a universal solution where a single Edison socket interface supports multiple functions: it can accommodate conventional AC bulbs, battery-powered LED bulbs, or serve as a charging station for battery bulbs. The socket becomes multi-functional, accepting both power delivery and battery charging operations through the same physical interface.
Solution Approach 2:
Instead of having the bulb contain the battery and conversion circuitry (which would compromise socket compatibility), the invention inverts the approach by placing the power conversion and charging infrastructure in the socket or on the ceiling mount, allowing the bulb to remain a simple, lightweight LED component with integrated battery that fits conventional sockets.
3Productivity
If conventional light fixtures are installed in unwired areas, then lighting can be provided, but extensive electrical work by electricians is required
Solution Approach 1:
The invention extracts the power conversion and electrical infrastructure requirements from the bulb itself and places them in a separate, portable charging station or ceiling-mounted unit. This allows the actual lighting bulb to be a simple, plug-and-play Edison socket component that can be installed anywhere without requiring electrical wiring, while the power conversion infrastructure is concentrated in dedicated charging locations.
