Light Fixture Bracket with Concealed Wireway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable lighting fixtures face issues with electrical conductor damage due to repeated movement and exposure, leading to insulation failure, potential short circuits, and unsightly routing of conductors, which affects reliability and aesthetics.
Innovation Solution
A lighting fixture design featuring a bracket with a concealed groove for electrical conductors, where a cover matches the bracket's perimeter to hide the conductors, providing protection and a cleaner appearance, while allowing for adjustable positioning of the light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical conductors are routed externally along the outside of lighting fixtures, then the conductors are easily accessible for connection, but the appearance becomes unsightly and conductors are exposed to environmental damage
Solution Approach 1:
The electrical conductors are nested within a wireway structure that is integrated into the lighting fixture housing. The wireway acts as a protective cavity that shields the conductors from external environmental factors while still allowing electrical connection to the light source.
Solution Approach 2:
The wireway serves as an intermediary structure between the external environment and the electrical conductors. It provides a protected pathway that isolates the conductors from direct exposure to ultraviolet rays, moisture, and physical damage while maintaining electrical functionality.
2Adaptability or versatility
If electrical conductors are made longer to provide slack for movement, then the light source can be adjusted more freely, but the conductors become more prone to damage from impact, tangling, and snagging
Solution Approach 1:
The wireway structure is designed to be flexible and movable, allowing the lighting fixture to be adjusted to different positions and angles. The wireway bends and moves with the fixture while protecting the conductors inside from damage, maintaining both adaptability and reliability.
Solution Approach 2:
The wireway structure provides beforehand protection for the electrical conductors by shielding them from potential damage sources such as impact, tangling, and snagging. This protective barrier is established in advance before the conductors are exposed to harmful conditions.
3Ease of operation
If oversized pivoting elbows or coiled metal wireways are used to allow conductor movement, then the conductors can move smoothly without constriction, but the device becomes bulky and oversized
Solution Approach 1:
The wireway structure provides flexibility and movement capability only in the specific areas where needed, such as at the mounting interface and near the light source, rather than making the entire fixture bulky. The wireway is designed to be compact while maintaining the necessary movement freedom for the conductors.

AI summary
A bracket device for mounting a light fixture comprising a flat grooved element and a flat cover to conceal and protect the electrical conductors powering the light source inside the lighting fixture is disclosed. When configured to swivel, the bracket device allows for adjustment of the light fixture without introducing significant wear or strain to the electrical conductors passing through the interior portion of the device. This bracket device is thin, compact and of very neat and simple appearance. Because of its thinness and its compact shape this device conceals and its main element can be made to have the same thickness as a prior art mechanical bracket element, which would not normally carry electrical conductors.
