Light Fixture Spring Carriage for Horizontal and Vertical Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light fixture assemblies face issues with horizontal movement of heat sinks due to multiple springs operating simultaneously, smaller apertures causing glare, and difficulty in accessing components like LEDs and optics without disrupting the ceiling's continuity.
Innovation Solution
A light fixture assembly with a carriage and springs allowing horizontal and vertical movement of a heat sink, combined with a baffle system to reduce glare and enable easy access to components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple springs are used to hold components in place, then the components are securely held, but the heat sink cannot move horizontally and must be moved at an angle which is undesirable
Solution Approach 1:
The spring mechanism is divided into multiple independent spring bands (first spring band and second spring band) that can operate independently. Each spring band is coupled to different laterally extending walls, allowing them to provide holding force in different directions and enabling horizontal movement without compromising component security
Solution Approach 2:
The invention introduces lateral movement capability by positioning spring bands in different spatial dimensions. The first and second laterally extending walls are spaced apart, allowing the heat sink to move horizontally between them while the springs provide vertical holding force, thus adding a horizontal degree of freedom to the previously constrained vertical movement
2Shape
If aperture size is reduced to make ceiling continuous and eliminate trim, then aesthetic appearance is improved, but access to components like LEDs and optics becomes difficult
Solution Approach 1:
The heat sink is designed with dynamic movement capability, allowing it to be shifted horizontally and vertically to different positions. This dynamic repositioning enables technicians to access components such as LEDs, optics, and drivers by moving the heat sink out of the way, while maintaining a clean, continuous ceiling appearance when the heat sink is in its operational position
3Shape
If aperture size is reduced, then ceiling continuity is achieved, but glare from the light fixture increases
Solution Approach 1:
A baffle is introduced as an intermediary element between the light source and the aperture. The baffle blocks direct light paths that would cause glare while still allowing the aperture to maintain its small size for ceiling continuity. The baffle acts as a mediator that modifies the light distribution pattern to reduce harmful glare effects
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy access to components within the assembly while maintaining ceiling continuity and reducing glare by using springs that allow horizontal and vertical movement of the heat sink, and a baffle system to minimize reflections.
Implementation Method 1
A spring is fixedly coupled to the second side wall extending between the second side wall and the light assembly. The spring is partially compressed by the light assembly while allowing horizontal and vertical movement of at least a portion of the light assembly.

AI summary
A light fixture assembly includes a carriage having a first side wall having a first opening therethrough, and a second side wall disposed opposite and spaced from the first side wall. A light assembly disposed at least partially within and coupled to the first side wall of the carriage. A spring is fixedly coupled to the second side wall extending between the second side wall and the light assembly. The spring is partially compressed by the light assembly while allowing horizontal and vertical movement of at least a portion of the light assembly.
