Rotable Light Assembly for Electronics Rack Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting in electronics racks is typically fixed, leading to poor illumination and shadows, making maintenance and inspection difficult due to inadequate directional control.
Innovation Solution
A rotatable light assembly with a light fixture, housing, and a mounting assembly that includes a base with a mounting flange, a support cradle with radial teeth, and a stanchion with an axle, allowing the light fixture to be securely attached to an electronics rack and rotated for optimal illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fixed lighting is used in electronics racks, then the lighting structure is simple and stable, but the illumination quality is poor and shadows are cast on equipment
Solution Approach 1:
The light fixture is made rotatable through a mounting assembly with an axle and curved surface, allowing dynamic adjustment of illumination direction to eliminate shadows and improve visibility during maintenance operations
2Ease of operation
If overhead lighting or portable flashlights are used, then no additional lighting structure is needed, but maintenance personnel cannot achieve consistent illumination and shadows are cast
Solution Approach 1:
The lighting system is self-contained within the rack structure, providing consistent illumination without requiring external portable light sources or overhead lighting, thereby improving both ease of operation and illumination consistency
3Adaptability or versatility
If a rotatable mounting assembly is added to the light fixture, then illumination direction can be adjusted for optimal lighting, but the device complexity increases
Solution Approach 1:
The mounting assembly is segmented into distinct components (base, support cradle, stanchion, axle, light mount) that can be independently manufactured and assembled, reducing overall complexity while maintaining rotatability and adaptability

AI summary
A light assembly with a light fixture and a rotatable mounting assembly. The mounting assembly includes a base that has a mounting flange with a cradle attached thereto that has an inner race with a curved surface and a plurality of teeth projecting radially inward. A stanchion is mounted adjacent to the cradle and has an axle extending laterally outward therefrom over the cradle. The axle has a center axis that is coaxial with a radial axis of the inner race. A light mount rotatably mounted to the base. The light mount includes a fixture bracket that is attached to the light fixture. The light mount includes a mount frame with an outer race that has a curved surface, and a hub mounted to the axle with an axis that is coaxial with a radial axis of the outer race and the axle axis.
