Flexible LED Module Magnetic Mounting for Reliable Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid-state lighting devices with flexible modules face challenges in achieving optimal adhesion and reliability when using bi-adhesive tapes, and alternative external supports are cumbersome and not widely adopted due to increased mounting time and risk of incomplete fixation.
Innovation Solution
The use of a magnetic attachment system, where a profile element with embedded magnetic material is integrated into the lighting module, allowing it to be securely attached and removed from a magnetically attractable support surface without the need for adhesives, preserving flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bi-adhesive tape is used to mount the flexible LED module, then the module can be attached to the mounting surface, but the adhesion reliability is low and the module may detach over time
Solution Approach 1:
The patent replaces the chemical adhesion mechanism of bi-adhesive tapes with a magnetic mechanical system. Magnets embedded in the module interact with magnetically attractable material on the mounting surface through magnetic forces, providing reliable and permanent attachment without the degradation issues of adhesive bonds.
Solution Approach 2:
The patent changes the mounting mechanism from chemical (adhesive) to physical (magnetic). By introducing magnetic elements and magnetically attractable material, the system utilizes magnetic field parameters to achieve secure mounting, transforming the fundamental attachment parameter from bond strength to magnetic force.
2Reliability
If a bi-adhesive tape is used for mounting, then the module can be fixed, but pressure must be exerted on electronic components during installation
Solution Approach 1:
The patent eliminates the need for mechanical pressure during installation by using magnetic attraction. The magnets and magnetically attractable material create a self-aligning, pressure-free mounting system where the module is drawn to the mounting surface through magnetic force rather than being forced into place by human pressure.
3Reliability
If a bi-adhesive tape is used, then the module can be mounted, but it becomes impossible to move the module after installation
Solution Approach 1:
The patent creates a dynamic mounting system where the magnetic connection can be easily changed from a fixed state to a removed state. By controlling the magnetic field strength and using removable magnetically attractable material, the system allows the module to be securely mounted during use but easily repositioned or removed when needed, providing adaptability while maintaining stability.
4Reliability
If external supports are used instead of bi-adhesive tape, then adhesion issues are avoided, but mounting time increases and fixation may be incomplete
Solution Approach 1:
The patent replaces complex external support structures with an integrated magnetic mounting system. The magnets are embedded directly in the module during manufacturing, and the magnetically attractable material is applied to the mounting surface, eliminating the need for separate external supports and reducing mounting steps while maintaining high fixation reliability.

AI summary
A lighting device includes at least one strip-like carrier member (10, 14) carrying electrically powered light radiation sources (12), e.g. LED sources, wherein said at least one carrier member (10, 14) includes magnetically attractive formations (16, 18) along the length of the at least one strip-like carrier member (10, 14). The lighting device can therefore be mounted on a magnetically attractable support structure, such as a metal plate, so that the lighting device is retained on the support structure (S) by the magnetic attraction force.
