Modular LED Luminaire with Rotating Chassis for Tool-Free Driver Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED luminaire systems are costly and inefficient to replace, upgrade, or repair due to the need to access components like drivers, which often requires disassembling complex structures and can be dangerous, leading to waste and lost productivity, and there is a lack of environmentally friendly solutions for upgrading lighting systems.
Innovation Solution
A modular LED luminaire design featuring a detachable component chassis with engaging elements that allow for easy access and servicing without tools, enabling the component chassis to be partially detached and rotated for maintenance or replacement while remaining securely attached, reducing the need to remove the entire frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If LED systems are designed with integrated drivers and components that require accessing troffers from above, then structural integrity and security are improved, but ease of repair and maintenance deteriorate
Solution Approach 1:
The LED luminaire is divided into separate functional modules: a driver module and a light module. The driver module can be independently accessed and replaced through the bottom access feature, while the light module remains secured. This segmentation allows maintenance of critical components without compromising overall structural integrity.
Solution Approach 2:
A bottom access feature acts as an intermediary mechanism that provides selective access to the driver module. This intermediary structure allows technicians to reach drivers from below without disassembling the entire luminaire or accessing from above, resolving the contradiction between security and ease of repair.
2Reliability
If LED systems require disassembling complex structures for component access, then security and protection of components are improved, but loss of time and productivity deteriorate
Solution Approach 1:
The luminaire is pre-designed with a bottom access feature and modular driver module configuration before installation. This preliminary structural arrangement ensures that future maintenance operations can be performed quickly without requiring complex disassembly procedures, thus reducing time loss while maintaining component protection.
Solution Approach 2:
The access mechanism incorporates movable or removable components that allow dynamic access to the driver module. Technicians can quickly open or remove the access panel from below, enabling rapid component replacement without time-consuming disassembly of fixed structures.
3Reliability
If entire troffers are discarded for LED upgrades, then reliability and performance are improved, but loss of substance and waste increase
Solution Approach 1:
The driver module is extracted as a separate, replaceable component from the luminaire housing. When upgrading LED systems, only the driver module needs to be removed and replaced, while the main luminaire structure and light modules can be retained and reused. This extraction approach eliminates the need to discard entire troffers, reducing waste while maintaining system performance.
Solution Approach 2:
The modular design enables selective discarding of only the obsolete driver module while recovering and reusing the luminaire housing, mounting structure, and light modules. This partial replacement strategy reduces material waste and landfill contribution compared to discarding entire troffers.
4Object-affected harmful factors
If access to drivers requires turning off electrical power and using tools, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The bottom access feature is designed to allow tool-free access to the driver module. The modular design includes quick-release connectors and snap-fit components that can be opened and manipulated by hand, enabling technicians to service drivers without requiring specialized tools or complex procedures.

AI summary
An LED luminaire is described that can be readily installed, removed, or replaced. The LED luminaire may be modular with an easily removable component chassis having components such as sensors, LED driver elements, and so forth that may be modular. The LED luminaire is adapted for rapid access to the component chassis and rapid adjustment, updating, repairs, or replacement thereof. In one aspect, one or more first engaging elements form a connection between the component chassis and the frame that can support the frame in either a closed or open position, or allow for rotation of the frame from one orientation to another while still securing the component chassis to the frame.
