LED Light Fixture Support Assembly with Adjustable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light fixtures face challenges in adjustable mounting and installation, particularly in high-position outdoor settings, where they are often large and heavy, and require complex structures that interrupt aesthetics and complicate installation.
Innovation Solution
A modular light fixture design featuring a rearward portion with a pivotable fulcrum and an engager to secure the fixture at desired angles, combined with a frame and heat sink that allows for easy orientation and adjustment, and a polymeric structure for reduced weight and improved clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If larger light fixtures are used for illuminating large areas, then illumination coverage is improved, but fixture weight and handling difficulty increase
Solution Approach 1:
The light fixture is divided into modular components including a housing, LED module, and mounting assembly that can be separately handled and assembled. This segmentation allows the fixture to provide large-area illumination while reducing handling difficulty during installation.
2Adaptability or versatility
If fixture-supporting structures are used to mount light fixtures, then mounting capability is improved, but aesthetic appearance deteriorates due to obtrusive structures
Solution Approach 1:
The mounting assembly is integrated into the housing structure itself, merging the support function with the aesthetic form. The mounting brackets and attachment mechanisms are designed to be concealed or minimal in appearance, allowing the fixture to maintain clean lines and aesthetic appeal while providing versatile mounting capabilities to various surfaces.
3Ease of operation
If adjustable mounting structures are added to allow orientation adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The mounting assembly incorporates adjustable elements such as pivoting brackets and rotatable connectors that allow the fixture to be oriented in multiple directions. These dynamic components enable installers to adjust the fixture angle and position during installation, and allow for future repositioning if needed, while maintaining a relatively simple overall structure.
4Length of moving object
If the horizontal dimension of the fixture is minimized, then fixture size and weight are reduced, but mounting adaptability is limited
Solution Approach 1:
The mounting assembly is designed to utilize vertical and depth dimensions rather than increasing horizontal footprint. Mounting brackets extend perpendicular to the fixture face, and attachment mechanisms use the depth dimension to provide secure mounting while keeping the horizontal projection minimal. This allows the fixture to adapt to various mounting surfaces without increasing its horizontal size.

AI summary
An LED light fixture including a housing, a heat sink secured with respect to the housing and an LED illuminator secured with respect to the heat sink. The heat sink includes central and peripheral portions. The central portion has an LED-supporting surface and forward, rearward and lateral sides, the LED illuminator being at the LED-supporting surface. The peripheral portion extends laterally from the lateral sides. The central portion of the heat sink has downwardly-extending shield members at the lateral sides thereof configured and dimensioned to block upward illumination. In embodiments where the optical member is configured for directing emitter light predominantly toward the forward side, the central heat-sink portion has a downwardly-extending shield member at the rearward side thereof configured and dimensioned to block rearward illumination.
