Light Fixture Finial Touch Control and LED Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures are not designed to fully utilize light-emitting diodes (LEDs), which emit light at higher intensities and produce heat, and lack proper structural and electrical support, leading to inefficiencies and inadequate light diffusion.
Innovation Solution
A light fixture design featuring a platform, trunk support, and finial, where the trunk support extends upwardly to house light sources and wiring, and the finial serves as both a decorative element and a touch control for electrical continuity, allowing for efficient LED usage and diffused light output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional light fixtures are used with LEDs, then LED lifespan and energy efficiency are improved, but structural support and electrical continuity are insufficient
Solution Approach 1:
The finial is designed to serve multiple functions: it acts as a decorative element, provides structural support by securing the shade to the trunk support, and serves as a touch control interface for the LED light source. This multi-functional design resolves the contradiction by ensuring reliable structural support while maintaining energy efficiency.
Solution Approach 2:
The finial acts as an intermediary component that bridges the electrical connection between the light source and the user interface. By being electrically connected to the light source and positioned as an accessible external element, it provides both structural support and reliable electrical continuity for touch control functionality.
2Use of energy by moving object
If conventional light fixtures are used with LEDs, then LED lifespan and energy efficiency are improved, but electrical continuity for control is insufficient
Solution Approach 1:
The finial serves as a multi-functional component that combines decorative aesthetics with touch control functionality. By making the finial electrically conductive and connecting it to the light source, it becomes an intuitive touch interface while maintaining the energy efficiency of LED operation.
Solution Approach 2:
The finial itself serves as the control interface without requiring separate buttons or switches. The decorative element that is already part of the light fixture structure becomes the control mechanism, allowing users to operate the light by simply touching the finial, thus improving ease of operation while maintaining energy efficiency.
3Illumination intensity
If point light sources are used, then LED intensity is improved, but light diffusion is insufficient
Solution Approach 1:
The patent introduces a shade component that adds a spatial dimension between the point light source and the environment. The shade diffuses the concentrated light from the LED in multiple directions, transforming the intense point source into a more distributed light pattern while preserving the high intensity output of the LED.
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
The design enhances LED efficiency and lifespan by providing structural support and diffusing point light sources, while the finial offers touch control functionality, improving overall light fixture performance.
Implementation Method 1
The finial is at least partially formed of a conductive material and is coupled with the wiring extending out the opening in the end of trunk support to maintain electrical continuity with the light source assembly

AI summary
A light fixture includes a platform, a trunk support, a light source assembly, and a finial. The trunk support is coupled to and extends upwardly from the platform. The trunk support defines an elongated cavity therein, exterior surfaces facing away from the elongated cavity, and an end opposite the platform. The end defines an opening to the elongated cavity. The light source assembly includes light sources and wiring in electrical communication with the light sources. The light sources are coupled to exterior surfaces of the trunk support, and the wiring extends from the light sources, into the elongated cavity, and out the opening in the end of the trunk support. The finial caps the top end of the trunk support. The finial is coupled with the wiring extending out the opening in the end of trunk support to maintain electrical continuity with the light source assembly.
