Retrofit LED Canopy Luminaire Assembly with Wire Guide Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing canopy luminaires using high-intensity discharge (HID) lamps require a cost-effective retrofitting solution to transition to energy-efficient LED-based lighting technology, considering the large installed base of HID-based luminaires in applications like petroleum service stations.
Innovation Solution
A retrofit LED canopy luminaire assembly is provided, which includes a retrofit adapter bracket and a wire guide body to facilitate the mounting of an LED luminaire, with electrical leads routed through the wire guide body and into the ballast housing, allowing for the replacement of HID lamps with LED lamps in existing canopy fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If LED-based lighting technology is used to replace HID lamps in existing canopy luminaires, then energy efficiency and maintenance ease are improved, but the complexity of retrofitting existing infrastructure increases
Solution Approach 1:
The retrofitting process is divided into separate functional components: a mounting bracket assembly for mechanical attachment, a wire guide body for electrical routing, and an LED luminaire unit. This segmentation allows each component to be optimized independently and simplifies the overall installation process by allowing modular assembly and disassembly.
Solution Approach 2:
The wire guide body acts as an intermediary component between the LED luminaire and the existing canopy fixture infrastructure. It provides a dedicated pathway for electrical leads, mediating the connection between the new LED technology and the existing ballast housing and mounting structure, thereby reducing installation complexity.
2Adaptability or versatility
If a retrofit adapter bracket is used to mount LED luminaires on existing canopy fixtures, then adaptability to existing infrastructure is improved, but the structural complexity of the mounting system increases
Solution Approach 1:
The mounting bracket assembly is designed as a universal interface that can accommodate various existing canopy fixture types while providing standardized mounting points for the LED luminaire. The bracket incorporates multiple functions including mechanical attachment, alignment guidance, and integration with the wire guide body, reducing the need for multiple specialized components.
Solution Approach 2:
The wire guide body is nested within or integrated with the mounting bracket assembly, and both are mounted to the existing canopy fixture. This nested arrangement allows the LED luminaire system to be contained within the existing fixture structure, minimizing the addition of external complexity while maintaining adaptability.
3Ease of operation
If electrical leads are routed through a wire guide body into the ballast housing, then ease of electrical connection is improved, but the precision required for proper lead routing and connection increases
Solution Approach 1:
The wire guide body is pre-formed with dedicated pathways and openings for electrical leads before installation. These pre-defined routes guide the leads from the LED luminaire through the mounting bracket and into the ballast housing, eliminating the need for precise manual routing during installation while ensuring proper connection alignment.
Solution Approach 2:
The wire guide body structure itself provides the routing function, using its own geometric features (passages, openings, and positioning protrusions) to automatically align and guide the electrical leads. This self-service approach eliminates the need for external routing tools or high-precision manual manipulation during installation.
