Extension Module Housing for Street Light Retrofit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing street light assemblies require complete replacement for modifications, which is costly and inefficient, especially in heavily trafficked areas where frequent changes are needed to meet evolving public needs.
Innovation Solution
An extension module with a housing that includes electronic components and sensors, positioned between the lighting fixture and the pole, allowing for in-situ retrofitting and extension of the street light assembly without replacing the entire fixture, using a longitudinal body with coupling members and access ports for conductor passage, and a housing with axial covers and circumferential covers to secure and house various electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire lighting fixture is replaced to meet changing public needs, then the system can be updated with new features, but the cost and time required for modification increase significantly
Solution Approach 1:
The invention divides the lighting system into separate functional modules: the existing lighting fixture remains in place while a new control module with electronic components (processors, sensors, communication interfaces) is installed independently on the pole structure. This segmentation allows updating the control system without replacing the entire lighting fixture, thereby reducing modification time and cost while maintaining adaptability to changing public needs.
2Adaptability or versatility
If the entire lighting fixture is replaced to integrate electronic components, then all desired functionality can be achieved, but the expense increases significantly
Solution Approach 1:
The invention extracts the electronic control components (processors, memory, sensors, communication interfaces) from the lighting fixture itself and places them in a separate module mounted on the pole. This extraction allows the control system to be updated independently of the lighting fixture, reducing expenses by avoiding unnecessary replacement of functional lighting components while still achieving full integration of electronic capabilities.
3Ease of manufacture
If a modular extension module is installed between the lighting fixture and pole, then modifications can be made cost-effectively, but the structural complexity of the assembly increases
Solution Approach 1:
The invention implements a nested structure where the extension module containing electronic components is housed within a mounting structure that attaches to the existing pole. The lighting fixture remains nested on top of this assembly. This nested doll approach consolidates multiple functions (structural support, electronic housing, conductor routing) into a compact integrated unit, reducing overall structural complexity while enabling cost-effective modifications through modular replacement of only the electronic module.

AI summary
A fixture for an elongate structure includes an extension module having a housing secured therearound. The extension module includes a longitudinal body portion having first connector and a second connector. One or more access ports extend through the longitudinal body portion and into an interior area of the longitudinal body portion. The extension module includes a first seating surface and a second seating surface. The housing includes a first axial cover extending radially and a second axial cover each extending radially outward from the longitudinal body. The first axial cover and the second axial cover are axially spaced apart from one another and define a space therebetween and around the longitudinal body portion. A circumferential cover extends circumferential around radially outermost edges of the first axial cover and the second axial cover and surrounding the space.
