Perimeter Light Strip Illumination for Uniform Substrate Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for illuminating substrates do not provide uniform 360-degree illumination around the perimeter from all viewing angles, and existing solutions often rely on back lighting or channel formation which are inefficient and aesthetically limited.
Innovation Solution
A flexible light strip is affixed along the perimeter of a substrate with inward-facing lights, such as LEDs, to achieve uniform and aesthetically pleasing illumination by surrounding the substrate 360 degrees.

Engineering Contradiction Analysis
1Illumination intensity
If back lighting or channel formation is used to illuminate substrates, then the substrate can be lit, but uniform 360-degree illumination from all viewing angles is not achieved
Solution Approach 1:
The illumination system is divided into multiple discrete light emitting diodes (LEDs) positioned around the perimeter of the substrate. Each LED acts as an independent light source, allowing for precise control and uniform distribution of light across the substrate surface from multiple angles.
Solution Approach 2:
The illumination approach transitions from traditional single-plane backlighting to a three-dimensional perimeter arrangement of LEDs. By positioning light sources around the entire perimeter of the substrate in multiple dimensions, 360-degree illumination is achieved, ensuring uniform lighting from all viewing angles.
2Ease of manufacture
If channels or grooves are formed in the substrate to mount LEDs, then illumination is possible, but manufacturing complexity and aesthetic limitations increase
Solution Approach 1:
The light emitting diodes are mounted on the outer perimeter surface of the substrate rather than being embedded within channels or grooves. This extraction of the mounting function from the substrate body eliminates the need for complex channel formation while maintaining aesthetic appearance and simplifying manufacturing.
Solution Approach 2:
The perimeter mounting structure serves multiple functions simultaneously: it provides mechanical support for the LEDs, creates the illumination function, and maintains the aesthetic appearance of the substrate edge. This multi-functionality eliminates the need for separate channel structures and simplifies the overall manufacturing process.

AI summary
A novel light strip system and methods for illuminating substrates. In one embodiment, the system includes a substrate with a light strip configured to be arranged around the edge of the substrate. The lights on the light strip are pointed inward towards the inside of the substrate to illuminate it. The flexible light strip may be secured along the edge of the substrate using countersunk edging. In other embodiments, the flexible light strip may be secured along the edge of the substrate using u-channel connectors. In yet other embodiments, the substrate may include a groove or channel abutting its edges to allow the insertion of the light strip inside of the substrate. The flexible light strip may then be secured by sealing the groove or channel.
