Modular Uplight Device for Luminaire Stem Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire uplight devices require secondary machining operations to the housing, increasing installation costs and the risk of water ingress, which can lead to damage and the need for full replacement.
Innovation Solution
A modular uplight device with a body having a radially outwardly directed annular flange and a vertically oriented annular rim, featuring a passageway that communicates with the luminaire's wireway and chamber, allowing for light emitting sources to be arranged in an array and emitting light in an opposite direction without the need for secondary machining, and incorporating an optical lens for sealing and optical control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional light sources are installed to provide uplighting capabilities, then the luminaire gains uplighting functionality, but installation costs increase due to additional hardware, labor, and secondary machining operations
Solution Approach 1:
The uplight device merges the additional light source functionality with the existing luminaire structure by integrating it into the housing. The device includes a housing that attaches to the luminaire housing, incorporating light sources, optical elements, and mounting mechanisms into a single integrated unit that combines uplighting functionality with structural integration.
Solution Approach 2:
The uplight device is segmented into separate modular components including a housing, light sources, optical elements, and mounting features. This segmentation allows the device to be manufactured separately and installed without secondary machining operations on the existing luminaire, reducing installation costs while maintaining versatility.
2Adaptability or versatility
If secondary machining operations are performed on the luminaire housing, then the uplight component can be installed, but the risk of water ingress increases significantly
Solution Approach 1:
The uplight device incorporates preliminary sealing actions through integrated sealing features that are pre-formed as part of the device housing. These sealing features engage with the luminaire housing to create water-tight seals before installation is complete, preventing water ingress without requiring secondary machining operations that would compromise the existing seal.
Solution Approach 2:
The uplight device housing acts as an intermediary element between the external environment and the luminaire interior. It incorporates sealing grommets, fasteners, and weather-resistant features that mediate the connection to the luminaire housing, blocking water ingress paths while enabling uplight installation without machining the original housing.
3Adaptability or versatility
If the luminaire housing is machined for uplight installation, then the uplight component can be mounted, but the structural integrity and sealing of the housing is compromised
Solution Approach 1:
The mounting capability is segmented into separate features on the uplight device housing rather than being integrated into the luminaire housing. The uplight device includes its own mounting brackets, fasteners, and attachment mechanisms that provide secure mounting without requiring any machining or modification of the original luminaire housing structure.
Solution Approach 2:
The uplight device housing serves as an intermediary mounting structure that provides attachment points and mounting capabilities. It includes integrated fasteners and mounting features that interface with the luminaire exterior or existing mounting points, enabling secure installation without compromising the structural integrity or sealing of the original luminaire housing.

AI summary
An uplight device for use with a luminaire that has a housing configured to be supported from a surface by a stem with a wireway. The uplight device includes a body having a radially outwardly directed annular flange, a vertically oriented annular rim encircling the annular flange, and a passageway extending through the body, and an uplight substrate supported on a first side of the annular flange. The uplight substrate includes a plurality of light emitting sources arranged in an array on a first side of the uplight substrate. The uplight device further includes an optical lens covering the first side of the annular flange and the uplight substrate. The body of the uplight device is configured to be coupled between the stem and housing of the luminaire such that the passageway communicates with the wireway of the stem and a chamber of the luminaire.
