Adjustable LED Architectural Lighting Fixture with Sealed Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Architectural lighting fixtures face challenges in flexibility, moisture resistance, maintenance, and adjustability due to the need for versatile designs that accommodate varying building configurations and demands for light intensity, distribution, and appearance.
Innovation Solution
An LED light fixture with an elongate housing and adjustable mounts, a lens with a flexible gasket, and a mounting plate with reflectors, allowing for 360° adjustment and sealing to accommodate different architectural needs, featuring tracks in arcs of circles for precise aiming and uniform product fabrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common fixture design is used, then manufacturing and design are simplified, but flexibility and adaptability to accommodate wide ranging architectural demands are reduced
Solution Approach 1:
The fixture is divided into separate functional modules: a housing containing LED lamps, adjustable mounts for positioning, and a lens assembly. This segmentation allows each component to be optimized independently while maintaining overall versatility.
Solution Approach 2:
The fixture design incorporates multiple adjustment mechanisms (longitudinal adjustment along the housing, angular adjustment via tracks in arcs of circles, and rotational adjustment for 360° facing) that enable a single fixture type to serve multiple architectural lighting needs.
2Ease of operation
If adjustable mounts with tracks in arcs of circles are added, then aiming precision and adjustability are improved, but device complexity increases
Solution Approach 1:
The tracks are arranged in arcs of circles rather than straight lines, enabling angular adjustment of the lens while maintaining a compact mounting structure. This curved geometry provides precise aiming capability without requiring complex mechanical assemblies.
3Reliability
If a rectangular seal channel and tapered seal ridge are used, then sealing effectiveness and moisture resistance are improved, but manufacturing precision requirements increase
Solution Approach 1:
The seal ridge is designed with a tapered geometry that changes its dimensions along its length, allowing it to progressively engage with the rectangular seal channel. This parameter variation provides self-aligning and self-sealing properties that reduce sensitivity to manufacturing tolerances.

AI summary
An LED light fixture includes a housing, a lens and a flexible gasket there between. Each of the housing and the lens has an elongate main body and two ends sealingly fixed to the main body. The assembly of components in the housing defines a sealing channel rectangular in plan and the lens similarly defines a sealing ridge. A mounting plate with light emitting diodes distributed on the mounting plate further includes a manifold plate positioned on the mounting plate which includes holes therethrough with reflectors about the holes to receive the light emitting diodes. Mounts supporting the elongate housing define longitudinally adjustable engagements with the housing. The mounts further include tracks arranged in arcs of circles located in planes perpendicular to the extension of the elongate housing. Munting brackets engage these tracks using retainers.
