Segmented LED Strip for Flexible Architectural Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED strips break electrical connections when twisted and suffer from overheating and compromised illumination when folded, making it difficult to achieve continuous, flexible illumination in architectural applications.
Innovation Solution
The LED strip is designed with two distinct sections: one for illumination and another for ensuring electrical continuity, allowing bending, folding, and bowing without breaking connections, featuring a knot-like second section for power transmission and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the LED strip is made with a continuous laminar support and connections, then electrical connection is maintained, but the strip breaks when twisted or folded
Solution Approach 1:
The LED strip is divided into separate sections with non-conductive portions between conductive sections. This segmentation allows the conductive parts to maintain electrical connection while the non-conductive parts provide flexibility and prevent breakage during bending or twisting operations.
Solution Approach 2:
The invention extracts the electrical connection function from the continuous laminar support by using discrete conductive sections connected by non-conductive sections. This separation allows the strip to be flexible and bendable while maintaining electrical continuity through the extracted conductive elements.
2Adaptability or versatility
If several LEDs are folded to follow architectural contours, then the strip can be installed on walls and ceilings, but the LEDs may overlap causing overheating
Solution Approach 1:
The LED strip is segmented into discrete sections with spacing between them. This segmentation prevents overlapping when the strip is folded or bent to follow architectural contours, thereby preventing overheating while maintaining adaptability to various shapes and surfaces.
3Adaptability or versatility
If the LED strip is folded or bent, then it can follow architectural surfaces, but illumination direction is compromised
Solution Approach 1:
The strip is divided into sections that can be independently positioned and oriented. This segmentation allows each section to follow the contours of architectural surfaces while maintaining proper illumination direction, as the discrete sections can be arranged to face the desired directions even when following complex surfaces.
4Illumination intensity
If a continuous LED strip is used, then illumination is continuous, but installation costs increase due to required splicing and cable connections
Solution Approach 1:
The LED strip is designed as segmented sections that can be directly connected end-to-end without requiring additional splicing or cable connections. The non-conductive sections serve as natural connection points, simplifying installation and reducing costs while maintaining continuous illumination through the series connection of LED sections.

AI summary
The invention relates to a LED strip with discontinuous illumination which does not break when bent, folded, or bowed, thereby providing correct illumination, even when bent, folded, or bowed. Said LED strip comprises at least a first section, in turn comprising a laminar support on one or both faces of which LEDs are attached, and a second section comprising at least one conductor connected to the first section, such that said strip can be bent, bowed, or folded by the second section in the same plane as that of the laminar support.
