LED Light Fixture Support Assembly with Adjustable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light fixtures face challenges in achieving efficient and easy installation, particularly in high-position outdoor settings, due to their size, weight, and limited adjustability, which complicates orientation and mounting, especially when aiming for a compact and aesthetically unobtrusive design.
Innovation Solution
The design incorporates a rearward portion with an exterior fulcrum and an engager to securely pivot and adjust the fixture's orientation, featuring a frame with rearmost extensions and a heat sink for thermal management, allowing for a smaller aperture and easier access, while maintaining adjustability and aesthetic considerations.
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 size and weight increase making them difficult to handle and install
Solution Approach 1:
The patent applies the dynamics principle by implementing an adjustable mounting mechanism that allows the fixture to be positioned at multiple angles and orientations. The mounting arm and adjustment mechanisms enable dynamic positioning of the heavy fixture, making it easier to install and orient during installation while maintaining the large size needed for broad illumination coverage.
2Ease of operation
If fixture-supporting structures are used to support light fixtures, then mounting capability is improved, but the structures may not be at a perfect desired angle requiring adjustment during installation
Solution Approach 1:
The mounting mechanism incorporates dynamic adjustment capabilities with multiple degrees of freedom, allowing the fixture to be positioned at various angles relative to the supporting structure. This enables installers to achieve desired orientations without requiring perfectly pre-positioned support structures, simplifying the overall installation process despite the added adjustment mechanisms.
Solution Approach 2:
The mounting mechanism is designed with multi-functionality to handle various mounting scenarios and orientations. The universal design allows the same mechanism to accommodate different support structures and achieve multiple fixture orientations, reducing the need for custom adjustment procedures for different installation scenarios.
3Length of moving object
If a compact fixture design is pursued to minimize horizontal dimension, then fixture size is reduced, but space for mounting structures and adjustment mechanisms is limited
Solution Approach 1:
The patent resolves the space constraint by extending mounting and adjustment mechanisms vertically rather than horizontally. The mounting arm and adjustment mechanisms are positioned above or below the main fixture body, allowing the fixture to maintain a compact horizontal footprint while still providing adequate space for mounting adaptability and orientation adjustment.

AI summary
An LED light fixture (10) including a housing (17), a heat sink (42) secured with respect to the housing and an LED illuminator (41) secured with respect to the heat sink. The heat sink includes cental and peripheral portions (45, 46). The central portion has an LED-supporting surface (43) and forward, rearward and lateral sides (2, 49, 50), 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 (65) 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.
