LED Connection Element With Integrated Light Guide for Modular PCB Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection elements for LED light modules are not adaptable to the varying shapes and sizes of printed circuit boards due to manufacturer-specific designs, leading to high inventory costs and a need for quick interchangeability, sustainability, and improved light quality without compromising safety and ease of handling.
Innovation Solution
A connection element with an annular frame divided into an outer and inner ring, where the inner ring forms part of a light directing component, allowing for pre-assembly and secure fastening through bayonet locks or screw fasteners, ensuring direct light emission into the light directing component and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple manufacturer-specific connection elements are stocked to accommodate varying printed circuit board shapes and sizes, then adaptability to different LED modules is improved, but inventory costs and device complexity increase
Solution Approach 1:
The connection element is designed with a standardized annular frame and contact arrangement that can universally accommodate different printed circuit board shapes and sizes through the recess configuration, eliminating the need for multiple manufacturer-specific variants while maintaining adaptability
2Productivity
If complete pre-assembled units of LED light modules with connection elements are stocked for quick delivery, then productivity and quick interchangeability are improved, but inventory costs and loss of substance increase
Solution Approach 1:
The system is segmented into standardized connection elements and variant light modules, allowing the connection element to be stocked once in a standardized form while light modules are assembled as needed, reducing inventory value while maintaining quick interchangeability
3Ease of operation
If the connection element design is simplified to reduce component count for easier handling, then ease of operation is improved, but light quality and reliability may worsen
Solution Approach 1:
The contact arrangement is merged with the annular frame structure, integrating the electrical contact function into the mechanical holding structure, which simplifies the overall component count and ease of handling while maintaining reliable electrical connection through the integrated design

AI summary
A connection element electrically connects an LED light module. The LED light module has a printed circuit board with contact springs for the electrical supply of the LED. The connection element includes an annular frame to cover the printed circuit board and to hold it mechanically on an arrangement surface of a counter bearing. A contact arrangement is mounted in the frame and serves to supply the LEDs with electricity. The frame is divided into an outer ring and an inner ring. The outer ring is provided to surround the printed circuit board and to hold it in the parallel direction to the arrangement surface of the counter bearing. The inner ring at least regionally surrounds the printed circuit board and is provided to hold the printed circuit board in the vertical direction to the surface of the counter bearing. The inner ring is implemented in a light directing component.
