Extension Cord Light Source Integrating LED Bulb With Power Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lighting solutions for construction and commercial settings, such as portable drop lights and extension cords, often result in a cluttered and hazardous environment due to multiple cords, and there is a need for a more integrated and efficient lighting solution that cooperates with extension cords.
Innovation Solution
A bulb-shaped light source with multiple LEDs, enclosed in clear plastic, is attachable to the end of an extension cord, featuring a switch for light control and a pilot lamp, eliminating the need for additional light units and allowing for multi-directional light beams, and can be easily removed and reconnected to other power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If portable drop lights and extension cords are used separately, then lighting is provided, but cord clutter and tripping hazards increase
Solution Approach 1:
The patent combines the extension cord and light source into a single integrated unit. The light source is attached directly to the extension cord, eliminating the need for separate drop lights and reducing cord clutter on the floor.
Solution Approach 2:
The extension cord serves dual functions: providing electrical power and providing illumination. This multi-functionality eliminates the need for additional lighting equipment in areas where extension cords are required.
2Adaptability or versatility
If multiple cords are used for power and lighting, then both functions are provided, but device complexity and safety risks increase
Solution Approach 1:
The extension cord and light source are merged into a single integrated device, reducing the number of separate cords and light units while maintaining both power and lighting functions.
3Illumination intensity
If conventional incandescent bulbs are used, then lighting is provided, but energy consumption and heat generation increase
Solution Approach 1:
The patent changes the type of light source from incandescent to LED, which fundamentally alters the energy conversion efficiency and reduces energy consumption while maintaining adequate illumination.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution minimizes cord clutter, provides adjustable lighting, and ensures safety by integrating the light source with the extension cord, reducing tripping hazards and electrical risks while offering a versatile and efficient lighting solution.
Implementation Method 1
A light source is attached or is attachable to the end of an extension cord. The light source may be bulb shaped source having multiple LEDs therein
Implementation Method 2
A pilot lamp is included in the bulb to indicate that the power is present and also provides a minimal light source until the bulb is activated
Data Source
AI summary
An extension cord light source provides a source of light without additional cords or light units. A light source is attached or attachable to the end of an extension cord. The light source may be a light bulb-shaped source having multiple LEDs therein. Clear plastic encloses the devices therein and allows for multi-directional light beams. The LEDs may connected to a switch with multiple positions for controlling the amount of light. The extension cord lines pass through the bulb and into an outlet being a female plug. This combination thus eliminates the need for a drop light. A removable shade may be also attached to the bulb to prevent unnecessary light. A pilot lamp is included in the bulb to indicate that the power is present. The bulb may have a male plug therein that will accept the female plug of a conventional extension cord.
