Backlit Lighting Assembly with Spaced Acoustic Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight lighting fixtures face issues with sound echoing, limited sound absorption effectiveness, heat transfer challenges, and difficult installation due to the configuration of backlighting spaces.
Innovation Solution
A lighting apparatus is designed with a lighting assembly and a sound absorbing assembly separated by an empty space, using attachment assemblies to form this gap, allowing increased sound absorption and thermal dissipation without interference, and enabling easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a backlighting space is formed between lighting fixtures and translucent material, then lighting function is achieved, but sound echoing occurs
Solution Approach 1:
A sound absorbing assembly is introduced as an intermediary component between the lighting assembly and the translucent material. This sound absorbing assembly includes sound absorbing material that captures sound waves entering the backlighting space, preventing them from echoing back into the occupied space. The attachment assemblies serve as mediators to position the sound absorbing assembly correctly without interfering with the lighting function.
Solution Approach 2:
The sound absorbing assembly is nested within the overall lighting fixture structure, with the attachment assemblies integrating multiple functions (mechanical support, spacing, and electrical connectivity). The attachment assemblies connect the lighting assembly, sound absorbing assembly, and translucent material in a nested configuration where each component serves its primary function without disrupting others.
2Object-generated harmful factors
If sound absorbing material is added to the backlighting space, then sound absorption improves, but heat transfer challenges arise
Solution Approach 1:
The backlighting space is segmented into distinct functional zones: a first portion for lighting where heat generation occurs, and a second portion for sound absorption where the sound absorbing material is positioned. This segmentation allows the lighting assembly to operate with adequate thermal management space while the sound absorbing material handles acoustic control in a separate zone, eliminating the conflict between heat transfer and sound absorption.
3Object-generated harmful factors
If conventional sound absorption techniques are used, then sound echoing is reduced, but installation difficulty increases
Solution Approach 1:
The attachment assemblies are designed with multi-functionality, serving as universal connectors that mechanically support the sound absorbing assembly, maintain proper spacing, and provide electrical connectivity pathways. This universal design simplifies installation by consolidating multiple requirements into single components rather than requiring separate elements for each function.
Solution Approach 2:
The attachment assemblies are configured to pre-establish the correct spatial relationships and connection pathways before final assembly. The attachment assemblies are designed with built-in features that guide proper positioning and alignment, allowing installers to simply connect components rather than perform complex alignment procedures during installation.
4Illumination intensity
If lighting fixtures are configured with backlighting space, then lighting performance is achieved, but device complexity increases
Solution Approach 1:
The lighting fixture is segmented into modular assemblies (lighting assembly, sound absorbing assembly, translucent material) connected by standardized attachment assemblies. This segmentation transforms a complex integrated system into manageable modules that can be independently handled and assembled, reducing overall device complexity while maintaining lighting performance.
