Modular Retrofit Lighting Assembly with Universal Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures are limited in their ability to accommodate new and more efficient light sources due to difficulties in retrofitting with different lighting technologies, often requiring replacement with similar fixtures rather than upgrading to better technologies.
Innovation Solution
A retrofit assembly comprising two lighting modules and a central hub, allowing for the integration of solid state light sources into existing fixtures of varying lengths, enabling the use of interchangeable components to adapt to different housing sizes and lengths, such as T5 and T8 fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing light fixtures are replaced with similar light sources, then installation compatibility is maintained, but lighting efficiency and technology advancement are limited
Solution Approach 1:
The retrofittable lighting assembly is designed with universal mounting features including multiple groups of mounting holes arranged in different patterns, allowing the same assembly to be installed in various housing types (T5, T8, and other fixtures) while maintaining high lighting efficiency through LED technology
2Use of energy by moving object
If existing light fixtures are retrofitted with different lighting technologies, then lighting efficiency is improved, but installation compatibility and ease of installation deteriorate
Solution Approach 1:
The lighting assembly is divided into separable components including a housing, mounting features with multiple hole groups, and lighting elements that can be independently installed or replaced, facilitating easy installation and maintenance while maintaining high lighting efficiency
Solution Approach 2:
The assembly incorporates universal mounting features with multiple groups of mounting holes in different patterns, enabling the same high-efficiency LED assembly to be easily installed in various housing types without requiring custom designs for each fixture type
3Adaptability or versatility
If multiple fixture types are maintained in inventory, then adaptability to different housing sizes is improved, but inventory complexity and cost increase
Solution Approach 1:
A single retrofittable lighting assembly design with multiple groups of mounting holes can be used across T5, T8, and other fixture types, eliminating the need to maintain separate inventory for different fixture sizes and reducing inventory complexity while maintaining universal compatibility
4Ease of operation
If traditional light sources are used in existing fixtures, then installation simplicity is maintained, but technological obsolescence and energy inefficiency occur
Solution Approach 1:
The lighting system is segmented into a retrofittable assembly that can be independently installed or replaced within existing fixtures, allowing traditional fixtures to be upgraded to modern LED technology while maintaining installation simplicity through modular replacement of the entire assembly
Solution Approach 2:
The retrofittable assembly enables parameter changes from traditional lighting technologies to modern LED technology, improving energy efficiency and reducing technological obsolescence while maintaining installation simplicity through standardized mounting interfaces

AI summary
A retrofit assembly includes at least first and second lighting modules, and at least a central hub positioned between the first lighting module and the second lighting module. Each lighting module includes a tray extending along a longitudinal axis and supporting a solid state light source on a seat defining a plane, a set of legs extending from each side of the seat, and a set of wings extending from the legs and parallel to the plane of the seat, the wings including first and second groups of mounting holes. First and second lenses might be provided to extend across a portion of the seats.
