Light Fixture Power Adapter with GFCI Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor electrical power distribution solutions fail to provide convenient and flexible power connections for external light fixtures without requiring replacement of fixtures or additional wiring, and often lack safety features like ground fault protection.
Innovation Solution
An external electrical power distribution apparatus that mounts between a standard external light fixture and a support structure, providing AC power outlets and connectors, including GFCI protection, while allowing for the use of existing light fixtures and optional sensors for automated switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external light fixtures are replaced with integrated power outlet fixtures, then electrical power distribution capability is provided, but the aesthetic preference and style choice of the original light fixtures is lost
Solution Approach 1:
The invention separates the power distribution function from the light fixture function by using an adapter module that interfaces between the light socket and the outlet. This segmentation allows the original light fixture to remain unchanged for aesthetic purposes while the adapter provides the needed power distribution capability.
Solution Approach 2:
The adapter module serves as an intermediary component that connects the existing light fixture wiring to external power outlets. It mediates between the original fixture design and the need for power distribution, allowing both functions to coexist without requiring replacement of the preferred light fixture.
2Adaptability or versatility
If adapters are installed in enclosed light fixtures, then power distribution is added, but physical accessibility for plugging in devices becomes difficult
Solution Approach 1:
The adapter extends power outlets to the exterior surface of the light fixture housing, moving the plug access point from the enclosed interior space to the external dimension. This allows users to access outlets without needing to open or disassemble the fixture enclosure.
Solution Approach 2:
The adapter is pre-installed within the fixture during initial setup, with outlets positioned and configured before use. This preliminary installation ensures that accessibility is built into the design, eliminating the need for future modifications or complex assembly steps.
3Adaptability or versatility
If standard adapters are used in enclosed fixtures, then power distribution is provided, but safety ground connection and GFCI protection are not available
Solution Approach 1:
The adapter module integrates multiple safety functions including ground connection terminals and GFCI protection circuitry into a single component that also provides power distribution. This multi-functionality ensures that safety requirements are met without adding separate complex systems.
Solution Approach 2:
The adapter includes built-in safety features such as automatic ground fault detection and interruption capabilities that operate autonomously to protect users. The device self-monitors and self-protects without requiring external safety systems.
