Illuminated Eyewear with Embedded LED Temple Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hands-free lighting devices, such as lighted eyeglasses, are often heavy, bulky, and aesthetically unpleasing due to conspicuous lighting modules and electronic components, which detract from their functionality and appearance.
Innovation Solution
The design incorporates LED light sources embedded within the eyewear's frame or temple arms, with pass-through portions in the cross-frame member to project light forwardly while hiding the lighting components from view, maintaining a traditional aesthetic and providing adjustable light intensity and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If separate and bulky lighting modules are fastened to the glasses, then illumination function is provided, but the glasses become heavy and bulky making them inconvenient to wear
Solution Approach 1:
The lighting module is integrated into the temple arm of the eyewear, merging the illumination function with the structural frame. The temple arm serves dual purposes: supporting the lens and housing the LED lighting module, eliminating the need for separate bulky lighting attachments.
Solution Approach 2:
The LED lighting module is nested within the temple arm structure, with the light source, battery, and control circuitry contained within the hollow interior of the temple arm. This nesting approach reduces overall volume and weight while maintaining illumination functionality.
2Illumination intensity
If lighting modules are mounted to the glasses, then illumination function is provided, but the presence of light modules or electronic components is visually prominent giving the glasses an unsightly appearance
Solution Approach 1:
The lighting module is extracted from the conventional external mounting positions and relocated into the temple arm structure. By taking out the light source from visible external positions and placing it within the temple arm's hollow interior, the aesthetic appearance is preserved while illumination function is maintained.
Solution Approach 2:
The temple arm is designed with differentiated local qualities: the outer surface maintains a smooth, aesthetic finish for visual appeal, while the inner hollow portion contains the lighting module and electronic components. This local differentiation allows the glasses to achieve both aesthetic appearance and illumination function simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides effective hands-free lighting that is both aesthetically pleasing and functional, allowing for directed illumination without the bulkiness and conspicuousness of previous designs, enhancing user experience and appearance.
Implementation Method 1
Adjacent to each of the outer front portions is a light source, which in the preferred form is an LED
Implementation Method 2
The pass-through portion is configured to allow light projected from the light source to project through the cross-frame portion to an area forwardly of the cross-frame portion

AI summary
There is provided illuminated eyewear having one or more light sources mounted thereto to project light forwardly thereof. The illuminated eyewear includes a cross-frame member or portion and temple arm members or portions extending rearwardly therefrom in a use configuration. The illuminated eyewear may include a pass-through portion of the cross-frame member that is oriented to be forwardly of the light source to allow light projected from the light source to pass therethrough to an area forwardly of the cross-frame member.
