Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire systems face challenges in efficiently connecting and aligning multiple luminaires to create a longer lighting field, with current solutions lacking a robust and easy-to-assemble mechanism for extending the length of lighting installations.
Innovation Solution
The design incorporates end caps with receptacles and posts that align orthogonally, allowing for secure mechanical and electrical connections between luminaires, enabling easy assembly and extension of luminaire assemblies with a three-point support system for alignment and connection.

1Length of moving object
If multiple luminaires are connected in an end-to-end fashion to create a longer lighting field, then the lighting field length is increased, but the alignment and connection complexity increases
Solution Approach 1:
The luminaire system is divided into modular units that can be independently manufactured and then connected together. Each luminaire module contains integrated end caps with connection features, allowing the lighting field to be extended by simply adding modules rather than dealing with complex continuous structures.
Solution Approach 2:
The connection features (receptacles and posts) and alignment features (guide surfaces) are merged into the end cap structures that are already part of each luminaire. This integration eliminates the need for separate connection hardware and simplifies the assembly process while enabling extended lighting fields.
2Ease of operation
If end caps with receptacles and posts are used to connect luminaires, then the ease of assembly is improved, but the device complexity increases due to additional components
Solution Approach 1:
The receptacles, posts, and guide surfaces are integrated into the end cap structures that are already part of each luminaire. This merging of functions reduces the need for separate connection hardware while maintaining ease of assembly through the intuitive post-to-receptacle connection mechanism.
Solution Approach 2:
The end caps serve multiple functions: they close the luminaire housing, provide structural support, enable mechanical connection between luminaires via posts and receptacles, and facilitate alignment through guide surfaces. This multi-functionality reduces the need for additional specialized components.
3Manufacturing precision
If guide surfaces are added to provide alignment and support, then the alignment precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The guide surfaces are integrated into the end cap structures during the same manufacturing process, eliminating the need for separate alignment components. This merging approach maintains manufacturing efficiency while providing precise alignment through the guide surface geometry.

AI summary
A luminaire has a light emitting portion extending between first second end caps to define a length between the first end cap and the second end cap. The first end cap comprises a receptacle and the second end cap comprises a post both of which extend in an insertion direction. The receptacles are configured to closely receive the posts and the insertion direction is disposed transversely to the length. A method of assembling a luminaire assembly includes positioning a first end cap of a first luminaire over a second end cap of a second luminaire; moving the first end cap relative to the second end cap in the insertion direction; and inserting the post into the receptacle. An electrical connector on the first end cap may connect with a mating electrical connector on the second end cap to complete an electrical connection between the first luminaire and the second luminaire.
