Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED modules lack effective protection against accidental contact, particularly with high-voltage LED circuit boards, posing risks to users and the LEDs themselves.
Innovation Solution
An LED module design featuring a contact protection element with a flat surface area oriented parallel to the LED circuit board, incorporating light-influencing areas and pin-shaped holding elements, which securely encloses the board and prevents accidental contact by being connected in a way that requires a tool for separation, ensuring reliable protection and compliance with safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a contact protection element is designed as a detachable profile part, then ease of operation is improved, but protection reliability deteriorates due to openings allowing access to the LED circuit board
Solution Approach 1:
The contact protection element is segmented into a flat protective plate and integrated optics modules, allowing the protection function and light emission function to be separated yet combined in a single component system
Solution Approach 2:
The contact protection element merges the protective cover function with the optical function by integrating light-influencing areas directly into the protection plate, eliminating the need for separate optics components and achieving full enclosure without compromising light emission
2Reliability
If a cover plate is used to cover the LED circuit board, then protection reliability is improved, but device complexity increases due to additional components
Solution Approach 1:
The contact protection element combines the protective cover and optical elements into a single integrated component, eliminating the need for separate cover plates and optics, thereby reducing device complexity while maintaining protection reliability
Solution Approach 2:
The contact protection element serves multiple functions simultaneously: it provides mechanical protection against contact, acts as an optical element for light emission, and serves as a structural component of the LED module, thereby reducing the total number of components required
3Reliability
If the contact protection element is positioned close to the LED circuit board, then protection reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The contact protection element is designed with pre-formed geometric shapes including recesses and protrusions that enable self-alignment and automatic positioning during assembly, eliminating the need for high-precision manual positioning and reducing manufacturing precision requirements
