Rotating Light Redirection Assembly for Wall Wash Luminaires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall wash luminaires are inconvenient and labor-intensive to adjust, as they require uninstallation and reinstallation to change the direction of light emission, limiting directional flexibility to only 180° opposite directions, and often necessitate impractical ceiling modifications for further adjustments.
Innovation Solution
A rotationally adjustable wall wash luminaire design featuring a slidingly rotatable light re-direction assembly with a reflector kicker and optical lens, allowing 360° directional adjustment without uninstalling the light fixture or trim assembly from the plaster ring, enabling easy direction changes while remaining installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light fixture is uninstalled and reinstalled in the plaster ring to change light direction, then the light direction can be changed, but the operation becomes inconvenient and labor intensive
Solution Approach 1:
The patent applies the dynamics principle by making the light fixture rotatable within the plaster ring. The fixture is designed with a rotational mechanism that allows it to pivot and adjust its orientation while remaining installed in the same location. This dynamic adjustment capability eliminates the need for uninstallation and reinstallation, enabling convenient directional changes without compromising adaptability.
2Adaptability or versatility
If the light fixture is uninstalled and reinstalled to change direction, then different directions can be targeted, but the process is labor intensive
Solution Approach 1:
The rotational mechanism enables the light fixture to dynamically change its orientation to target different directions. This dynamic adjustment allows the fixture to cover multiple directions and angles without requiring physical removal and reinstallation, significantly improving adjustment efficiency and productivity while maintaining full directional coverage capability.
3Adaptability or versatility
If the plaster ring is uninstalled and reinstalled to rotate the light, then light direction can be changed, but ceiling modifications are required which increases labor cost
Solution Approach 1:
The patent implements a rotational mechanism within the existing plaster ring structure that allows the light fixture to be adjusted dynamically without removing the plaster ring from the ceiling. This eliminates the need for ceiling modifications and complex uninstallation/reinstallation processes, reducing installation complexity while preserving full light direction flexibility.
4Device complexity
If only two torsion spring receivers are provided in the plaster ring, then the structure remains simple, but the light direction is limited to two positions
Solution Approach 1:
Instead of adding multiple fixed receivers to expand directional options, the patent employs a rotational mechanism that allows the light fixture to continuously adjust its orientation. This dynamic approach provides unlimited directional options within the rotational range while maintaining the simplicity of the original two-receiver structure, avoiding increased device complexity.

AI summary
A wall wash luminaire includes a trim assembly that has a trim and a light re-direction assembly. The light re-direction assembly includes a reflector kicker that is configured to re-direct light from the wall wash luminaire and an optical lens that is coupled to the reflector kicker such that the reflector kicker and the optical lens operate as a single unit. The light re-direction assembly is removably coupled to the trim such that the light re-direction assembly is slidingly rotatable with respect to the trim and 360 degrees about a central axis of the trim assembly.
