Telescoping Perimeter Lighting Fixture With Sliding LED Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of linear and perimeter lighting fixtures is challenging due to varying wall dimensions and obstacles, requiring extensive field cutting and skilled labor, which increases costs and time.
Innovation Solution
A telescoping lighting fixture with a mounting rail and sliding LED boards allows for adjustable length, enabling easy fitting into defined spaces with minimal measuring and cutting, and can be installed in parts to simplify the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telescoping lighting fixtures are used to accommodate varying wall dimensions, then adaptability improves, but installation complexity and time increase due to required field cutting and precision adjustments
Solution Approach 1:
The lighting fixture is divided into a main body section and a separate telescoping extension section that can be independently adjusted. The extension section includes a sliding mechanism with guide rails and mounting brackets that allow the LED board to be positioned at different lengths without requiring field cutting of the main fixture body.
Solution Approach 2:
The fixture incorporates a dynamic telescoping mechanism where the extension section can slide along guide rails to adjust the overall length. This dynamic adjustment capability allows the fixture to adapt to varying wall dimensions while maintaining a simple, tool-free installation process through built-in mounting brackets and alignment features.
2Manufacturing precision
If telescoping lighting fixtures are used to fit precise spaces, then manufacturing precision requirements decrease, but installation time increases due to extensive field cutting and adjustment
Solution Approach 1:
The telescoping mechanism and adjustment features are pre-integrated into the fixture design during manufacturing. The extension section, guide rails, and mounting brackets are assembled as a complete unit before installation, eliminating the need for field cutting or complex adjustments during installation.
Solution Approach 2:
The fixture includes self-aligning features such as guide rails and mounting brackets that automatically position the extension section correctly during installation. The design allows installers to simply slide the extension into place without requiring precision measurements or specialized tools, making the installation process self-explanatory and rapid.
3Device complexity
If fixed-length lighting fixtures are used, then device complexity is reduced, but adaptability to varying wall dimensions deteriorates
Solution Approach 1:
The telescoping extension section is designed to nest within or attach to the main body of the fixture. The extension can be stored in a compact position during shipping and then extended during installation, allowing a single fixture to provide multiple length configurations without increasing overall device complexity.

AI summary
A lighting fixture includes a mounting rail slidably attached to a first side of a main section. A lighting assembly includes a first LED board attached to the main section, and a second LED board attached to an extension movable longitudinally relative to the main section. The extension may be attached to the mounting rail and be slidable longitudinally relative to the main section, to extend the length of the lighting fixture. The second LED board may be supported on a slider extrusion rigidly attached to a spacer on the main section. The lighting fixture can be more quickly and easily installed with minimal field cutting of components.
