OLED Acoustic Ceiling Panel Merging Lighting and Sound Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic ceiling panels lack integrated lighting functionality, which limits their ability to enhance both acoustic properties and illumination in architectural and interior design applications.
Innovation Solution
An acoustic and illuminating ceiling panel is designed with a layer of acoustic absorbent material and integrated organic light-emitting diode (OLED) modules, which provide lighting while maintaining or improving acoustic absorption coefficients, allowing for uniform sound distribution and adjustable lighting levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic ceiling panels are used to cover the ceiling, then acoustic properties are improved, but lighting functionality is lacking
Solution Approach 1:
The patent combines acoustic absorption and lighting functions into a single ceiling panel by integrating OLED modules directly into the acoustic panel structure. The OLED modules are positioned on the rear face of the acoustic absorbent material, allowing the panel to simultaneously provide acoustic correction and illumination without requiring separate lighting fixtures.
Solution Approach 2:
The ceiling panel is designed to perform multiple functions: acoustic absorption through the porous material and lighting through integrated OLED modules. This multi-functional design eliminates the need for separate acoustic panels and lighting fixtures, allowing a single element to serve both purposes effectively.
2Adaptability or versatility
If light fittings are added to acoustic ceiling panels, then lighting functionality is improved, but acoustic zones become non-uniform
Solution Approach 1:
The lighting function is distributed through multiple small OLED modules positioned at specific locations on the rear face of the acoustic panel, rather than using a single centralized light fitting. This distributed arrangement ensures that acoustic properties remain uniform across the entire panel surface while still providing adequate lighting coverage.
3Adaptability or versatility
If OLED modules are integrated into acoustic panels, then lighting and acoustic functions are combined, but device complexity increases
Solution Approach 1:
The ceiling system is divided into modular acoustic panels, each containing integrated OLED modules. This segmentation allows for standardized manufacturing and installation while maintaining acoustic performance. The modular approach simplifies the overall system complexity by breaking down the integrated functionality into manageable, replaceable units.
