Movable Light Engine Bracket for Enclosed Fixture Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern lighting devices installed in enclosed environments, such as ceilings or walls, often present difficulties in accessing the light source and driver electronics for maintenance or adjustment without removing the entire system, and there is a need for configurations that allow for easy access and adjustable light emission directions.
Innovation Solution
A lighting device system with a base and a light engine support bracket assembly that can move between positions to align either the light source or the driver electronics with a light opening, allowing for easy access and adjustment, featuring guide rails, pivotable, and rotatable structures, along with a heat sink for thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lighting device system is installed in an enclosed environment (ceiling, wall, or housing), then the lighting device provides stable operation and proper light emission, but it becomes difficult to access the lighting device, driver electronics, or components for replacement, inspection, or servicing
Solution Approach 1:
The lighting device system is divided into separable components: the base remains installed in the enclosed environment while the light engine support bracket assembly can be independently moved and removed. This segmentation allows the base to maintain stable operation while the light engine assembly can be accessed for servicing through the light opening.
Solution Approach 2:
The light engine support bracket assembly is made movable relative to the base through guide rails and support structures. This dynamic configuration allows the assembly to be shifted between an operational position (aligned with the light opening for light emission) and a servicing position (where components are accessible through the light opening), resolving the contradiction between stable installation and ease of repair.
2Reliability
If the lighting device is fixed in position for stable operation, then light emission is consistent, but adjustment of light emission direction becomes difficult or impossible
Solution Approach 1:
The light engine support bracket assembly incorporates pivotable and rotatable structures that enable dynamic adjustment of the light engine assembly's orientation. The assembly can be rotated about a first axis and pivoted about a second axis, allowing directional adjustment of light emission while maintaining a stable base installation. This provides adaptability in light direction without compromising the stability of the installed system.
3Ease of repair
If the light engine support bracket assembly is made movable for ease of access and adjustment, then components are accessible and light direction is adjustable, but the structural complexity of the mounting system increases
Solution Approach 1:
The movable and adjustable functions are extracted into a separate light engine support bracket assembly that can be independently manipulated. This bracket assembly contains the guide rails, support structures, and adjustment mechanisms, separating the complexity from the base and allowing the base to remain simple while providing access and adjustment capabilities through the extracted functional module.
4Illumination intensity
If the light source is positioned for optimal light emission, then lighting performance is maximized, but access to the light source for maintenance becomes restricted
Solution Approach 1:
The light engine support bracket assembly allows the light source to be dynamically repositioned along the guide rails and rotated about multiple axes. The light source can be moved to an optimal position for light emission performance, and then the entire assembly can be shifted to a maintenance position where the light source becomes accessible through the light opening without requiring removal of the base from the enclosed environment.

AI summary
A moveable mount supports a lighting device assembly and driver electronics. The moveable mount includes a base having a light opening, and a light engine support bracket assembly movably secured to the base. The light engine support bracket is configured to support the lighting device assembly and the driver electronics, for movement relative to the base between a first position in which an optic or a light source of the light engine assembly is aligned with the light opening of the base to direct light through the light opening, and a second position in which the driver electronics is aligned with the light opening of the base.
