Rotatable Trim Assembly for Recessed Luminaire Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recessed luminaires often require specific installation orientations for optimal wall wash patterns, and incorrect installation leads to costly and destructive reinstallation processes to correct lighting direction.
Innovation Solution
A rotatable trim assembly within the luminaire, secured by a securing assembly flange and securing member assemblies, allows for adjustable light dispersion without the need for reinstallation, enabling flexible orientation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing of a recessed luminaire is installed in a specific location or orientation to direct light to the intended wall, then the wall wash pattern is optimized, but if installation instructions are not followed, the lighting is directed to unintended targets requiring costly and destructive reinstallation
Solution Approach 1:
The patent applies the dynamics principle by making the trim assembly rotatable relative to the housing after installation. The trim can be rotated to different orientations (e.g., 0°, 45°, 90°, 135°) to redirect light to different walls, transforming a static installation into a dynamic, adjustable system that adapts to different lighting needs without requiring reinstallation of the housing.
2Adaptability or versatility
If the trim assembly is made rotatable to allow adjustment of light dispersion, then adaptability and ease of operation are improved, but the device complexity increases due to the securing assembly and rotatable mechanism
Solution Approach 1:
The patent applies segmentation by dividing the luminaire into distinct functional modules: a housing, a rotatable trim assembly, and a securing assembly with multiple securing members. This modular design allows the trim to be independently rotated and repositioned without affecting the housing or other components, simplifying the overall system architecture while enabling adjustability.
Solution Approach 2:
The securing assembly acts as an intermediary between the housing and the rotatable trim assembly. It provides a mechanical interface that allows the trim to be securely attached while permitting rotation, mediating between the need for stable installation and the need for adjustable orientation.
3Reliability
If multiple securing member assemblies are used to secure the trim flange, then reliability of attachment is improved, but the ease of repair and maintenance worsens due to the complexity of disassembly
Solution Approach 1:
The securing members are designed to be manually operable without requiring special tools, allowing users to easily disassemble and reassemble the trim assembly for maintenance or repositioning. The self-service design enables end-users to perform simple repairs and adjustments themselves, improving ease of maintenance while maintaining reliable attachment through the multiple securing members.

AI summary
A luminaire can include a securing assembly having a securing assembly flange and a plurality of securing assemblies disposed on the securing assembly flange, where each of the plurality of securing assemblies secures a collar of a heat sink assembly against the securing assembly flange in a fixed position. The luminaire can also include a trim assembly comprising a trim body having a trim flange fixedly disposed atop a trim side wall, wherein the trim flange is secured by the plurality of securing assemblies, wherein the trim assembly is rotatable while the trim flange and the collar are secured by the plurality of securing assemblies.
