Flexible Lighting Accessory with Reflective Screen for Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices with linear substrates face limitations in flexibility and light distribution due to their strip-like conformation, restricting their assembly and configuration possibilities.
Innovation Solution
A flexible accessory with a light-permeable body and a reflective screen is applied to standard front- or top-emitting LED lighting devices, allowing for improved flexibility and light distribution by reflecting light sideways, enabling the use of standard LEDs without side-emitting sources and masking internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strip-like substrate is used for lighting devices, then protection against external agents can be provided, but flexibility and bending possibilities are limited
Solution Approach 1:
The lighting device is divided into modular segments that can be independently bent and configured. The strip-like substrate is segmented into multiple sections with flexible connections, allowing each segment to be positioned independently while maintaining overall structural integrity and protection against external agents.
Solution Approach 2:
The lighting device transitions from a strictly planar two-dimensional configuration to a three-dimensional spatial arrangement. By introducing vertical and angular dimensions through flexible mounting and segment orientation, the device can wrap around surfaces and adapt to complex geometries while maintaining protective encapsulation.

3Ease of manufacture
If the substrate structure is simplified for ease of manufacture, then manufacturing precision and light distribution control are reduced
Solution Approach 1:
The lighting device is divided into modular segments that can be independently bent and configured. The strip-like substrate is segmented into multiple sections with flexible connections, allowing each segment to be positioned independently while maintaining overall structural integrity and protection against external agents.
Solution Approach 2:
The device incorporates adjustable parameters such as flexible segment angles, spacing, and orientation that allow post-manufacturing tuning of light distribution characteristics. This enables standard manufacturing processes to produce components that can be precisely configured during installation to achieve desired optical performance.
