Peripheral Light-Strip Eyewear for Shadow-Free Workspace Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminated eyewear fails to provide adequate, shadow-free illumination of the wearer's workspace, often creating shadows and being weaker than ambient light, limiting its effectiveness in various work environments.
Innovation Solution
Eyewear with circumambient illumination, utilizing light sources disposed around the eyes or periphery to emit at least 50 lumens of light uniformly, eliminating shadows by providing illumination from multiple angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional illuminated eyewear uses light sources disposed in front of the eyes, then the structure is simple, but shadows are created in the workspace and illumination is inadequate
Solution Approach 1:
The light sources are positioned at the periphery of the eyewear rather than directly in front, utilizing the lateral dimension to illuminate the workspace from multiple angles. This peripheral disposition allows light to reach the workspace from the sides and below, eliminating shadows that would be cast by front-mounted lights while maintaining structural simplicity.
Solution Approach 2:
The illumination system is divided into multiple separate light sources disposed at different locations around the eyewear periphery. Rather than using a single light source, multiple segmented light sources work together to provide comprehensive illumination from various angles, eliminating shadows while keeping each individual light source simple and manageable.
2Illumination intensity
If light sources are disposed around the periphery of the eyewear, then shadow-free illumination is achieved, but device complexity increases
Solution Approach 1:
The eyewear frame structure serves multiple functions: it supports the lenses, provides the mounting structure for light sources, and defines the periphery where light sources are disposed. This multi-functionality allows the same structural elements to handle both mechanical support and illumination positioning, reducing overall device complexity despite the sophisticated light arrangement.
Solution Approach 2:
The illumination system is merged with the eyewear frame structure, where light sources are integrated into the frame rather than being separate add-on components. This merging allows the frame to simultaneously serve as both structural support and illumination platform, simplifying the overall device architecture while achieving uniform shadow-free illumination.

AI summary
Circumambient illumination eyewear includes one or more lenses, a frame configured to support the lens(es) on a user's face at least partially around the user's eyes, at least one illumination strip mounted to the frame and/or the at least one lens and configured to emit light, and a battery configured to be electrically coupled to the illumination strip(s). The illumination strip(s) extend at least along a top portion of the eyewear and along a bottom portion of the eyewear and are configured to face away from the user's face to create an illuminated and shadow-free workspace facing the circumambient illumination eyewear.
