LED Light Engine Retrofit Kit with Hook and Mounting Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED retrofit kits are not generally compatible with various sizes and configurations of fluorescent light fixtures, making them difficult to install and requiring access to the ceiling area, which poses safety hazards and increased costs.
Innovation Solution
A retrofit kit comprising a light engine with a hook bracket for suspension and a mounting bracket for secure installation, allowing single-worker installation without disturbing the ceiling, and compatible with different fixture dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional fluorescent fixtures are replaced with LED fixtures, then lighting efficiency is improved, but installation complexity and cost increase due to ceiling access requirements
Solution Approach 1:
The invention divides the LED lighting system into separate components: a removable light engine containing LEDs and a mounting bracket system that attaches to the existing fixture. This segmentation allows the LED component to be installed independently without removing the entire fixture, eliminating ceiling access requirements while maintaining energy efficiency benefits
Solution Approach 2:
The patent extracts the LED light engine as a separate replaceable component from the traditional integrated fixture design. This extraction enables installation without disturbing ceiling structures, as the LED engine can be mounted directly onto the existing fixture housing through the bracket system
2Manufacturing precision
If LED retrofit kits are designed for specific fixture configurations, then installation precision is improved, but adaptability to different fixture sizes decreases
Solution Approach 1:
The mounting bracket is designed with universal compatibility features, including adjustable mounting positions and multiple attachment configurations, allowing it to fit various fixture sizes and types (T5, T8, T12) while maintaining precise installation through standardized mounting holes and alignment features
3Reliability
If LED replacement requires access to ceiling area, then installation reliability is improved through proper wiring access, but safety hazards and cleanup requirements worsen
Solution Approach 1:
The mounting bracket is pre-designed with integrated wiring access features and pre-drilled mounting holes, allowing electrical connections to be made from the fixture level without ceiling access. This preliminary design eliminates the need to disturb ceiling structures, preventing asbestos release and dust contamination while maintaining installation reliability through proper wiring integration

AI summary
Retrofit kits for retrofitting LED light engines into existing light fixture housings. The retrofit kit includes a hook bracket that may be mounted in the housing and from which an end of the LED light engine can be suspended so as to permit an installer to electrically connect the LED light engine. The retrofit kit also includes a mounting bracket to secure the free end of the LED light engine into the housing after the LED light engine has been rotated upwardly into the housing from the hanging position.
