Bendable LED Fixture Segmented Profile for Contouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting fixtures lack flexibility and water resistance, making them unsuitable for contouring to various surfaces and withstanding outdoor or moisture-exposed environments, especially in applications like walkways and underwater installations.
Innovation Solution
A bendable lighting fixture with a flexible profile and polyurethane filling material, capable of being bent or flexed in multiple directions, featuring a translucent or transparent lens to obscure individual LEDs and provide water resistance, suitable for indoor and outdoor use on contoured surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting fixtures are used, then structural stability is maintained, but flexibility and ability to contour to surfaces is lost
Solution Approach 1:
The lighting fixture is divided into modular segments that can be independently positioned and connected. Each segment contains its own lighting elements and can be arranged to follow complex surface geometries while maintaining overall structural integrity through standardized connection interfaces.
Solution Approach 2:
The patent employs flexible housing structures and thin-walled components that can bend and conform to surfaces. The fixture incorporates flexible circuits, bendable mounting elements, and compliant structural features that enable contouring to irregular surfaces without compromising the protective enclosure or electrical connectivity.
2Reliability
If conventional lighting fixtures are used, then manufacturing simplicity is maintained, but water resistance and durability in outdoor environments is lost
Solution Approach 1:
The lighting elements, circuits, and components are nested within a sealed housing structure. The fixture incorporates nested protective layers including gaskets, seals, and waterproof coatings that protect internal components from moisture while maintaining a compact, integrated design that can be manufactured as a unified assembly.
Solution Approach 2:
The patent utilizes composite construction combining multiple materials with complementary properties: corrosion-resistant metals for structural components, waterproof polymers for seals and housings, and protective coatings for surface durability. This composite approach achieves superior water resistance and outdoor durability while allowing each material to be optimized for its specific function.
3Illumination intensity
If individual LEDs are visible, then light output efficiency is maintained, but aesthetic quality and light distribution uniformity is worsened
Solution Approach 1:
The patent introduces optical intermediaries such as diffusers, lenses, and light guides positioned between the LED sources and the external environment. These optical elements redistribute light from discrete LED chips to create uniform illumination patterns, eliminate visible individual LED dots, and maintain high overall light output efficiency through optimized light extraction and distribution.
