Collapsible Ceiling Light Fixture with Batwing Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional light fixtures for ceiling grid systems are large, costly to ship, and have poor acoustical performance, as well as a discontinuous appearance with ceiling tiles, and are cumbersome to assemble and install.
Innovation Solution
A modular, collapsible, and expandable light fixture designed for ceiling grid systems, featuring a support member, light source, and a monolithic wall assembly that is adjustable between a folded and unfolded configuration, providing indirect lighting with an asymmetric batwing light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional light fixtures are used for ceiling grid systems, then lighting function is provided, but shipping costs and carbon emissions increase due to large size
Solution Approach 1:
The light fixture is divided into multiple modular components including a light engine assembly, monolithic wall assembly, and ceiling grid interface assembly that can be separately manufactured and shipped, then assembled on-site to form the complete fixture
Solution Approach 2:
The monolithic wall assembly is designed to be collapsible between a folded configuration for compact shipping and an unfolded configuration for installation, allowing the fixture volume to dynamically change based on operational needs
2Reliability
If traditional light fixtures are used for ceiling grid systems, then lighting function is provided, but acoustical performance is poor
Solution Approach 1:
The monolithic wall assembly is formed from acoustic-absorbing material that provides both structural support and acoustic treatment functionality, creating a composite structure that addresses both mechanical and acoustic requirements
Solution Approach 2:
The fixture integrates multiple functions including structural support, acoustic absorption, and lighting into a single unified assembly, eliminating the need for separate acoustic tiles and simplifying the overall ceiling system
3Shape
If traditional light fixtures are used for ceiling grid systems, then lighting function is provided, but appearance is discontinuous with ceiling tiles
Solution Approach 1:
The monolithic wall assembly is designed to be substantially indistinguishable from adjacent ceiling tiles when viewed from below, creating visual homogeneity across the entire ceiling surface and eliminating the appearance of discontinuity
Solution Approach 2:
The light engine assembly is positioned and configured to provide asymmetric batwing light distribution that illuminates the space below while maintaining the uniform appearance of the ceiling surface, with lighting function localized to specific areas
4Ease of operation
If traditional light fixtures are used for ceiling grid systems, then lighting function is provided, but assembly and installation are cumbersome
Solution Approach 1:
The fixture is divided into pre-assembled modular components that can be independently handled and positioned, then quickly connected together on-site, reducing the complexity and time required for installation
Solution Approach 2:
The modular components are designed with self-aligning features and tool-less assembly mechanisms that allow installers to easily connect the light engine assembly, monolithic wall assembly, and ceiling grid interface assembly without specialized equipment or complex procedures

AI summary
A lighting system for a ceiling grid system may provide lighting at a location below the ceiling grid system. The light fixture includes a light source and a support member, and the light fixture may provide diffusely reflected light to a ceiling grid opening. The light fixture may include a wall assembly that is adapted to be moved between a folded configuration and an unfolded configuration.
