LED Illuminator Face Lens for Uniform Facial Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED masks fail to provide uniform light distribution and customized light therapy for facial skin, often causing nonuniform irradiation and direct radiation to the eyeball, leading to discomfort and reduced therapy effectiveness.
Innovation Solution
The integration of a face lens with adjustable wavelength, direction, and intensity settings for LEDs, along with an orbital light irradiation unit and eye patch unit, ensures uniform light distribution and prevents direct radiation to the eyeball, allowing for customized therapy on areas like the infraorbital margin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If LEDs are arranged without consideration of facial shapes, then device complexity is reduced, but uniformity of light irradiation deteriorates
Solution Approach 1:
The patent applies local quality by dividing the facial treatment area into multiple zones (forehead, cheek, chin, etc.) and arranging LEDs specifically for each zone based on facial anatomy. Each zone receives optimized light irradiation according to its specific needs, achieving uniform coverage across the entire face without requiring complex overall redesign.
Solution Approach 2:
The patent segments the facial treatment area into distinct regions and places LED arrays in each segment. This segmentation allows independent optimization of light distribution for each facial zone, solving the uniformity problem without increasing overall device complexity.
2Illumination intensity
If light sources are positioned close together to increase irradiation intensity, then illumination intensity improves, but harmful factors increase due to overlapping light and nonuniform distribution
Solution Approach 1:
The patent positions LED light sources at specific intervals corresponding to different facial zones, ensuring each zone receives appropriate light intensity without excessive overlap. This local optimization prevents harmful effects while maintaining effective treatment intensity in each region.
3Reliability
If light blocking means press the periphery of the eyeball, then reliability of eye protection improves, but harmful factors increase due to discomfort and headache
Solution Approach 1:
The patent introduces an optical guide as an intermediary between the LED light source and the treatment area around the eye. The optical guide channels light to the infraorbital margin and periorbital regions while preventing direct light exposure to the eyeball, eliminating the need for pressing contact blocks and associated discomfort.
4Reliability
If light blocking means press the periphery of the eyeball, then eye protection improves, but productivity deteriorates due to inability to irradiate infraorbital margin
Solution Approach 1:
The patent uses an optical guide as an intermediary to deliver light precisely to the infraorbital margin and periorbital areas while blocking direct light from reaching the eyeball. This enables effective treatment of previously inaccessible areas without compromising eye protection.
Solution Approach 2:
The patent extends light treatment to the infraorbital margin and periorbital regions by utilizing the optical guide structure that operates in a different spatial dimension, allowing light to reach areas that were previously blocked by conventional eye protection mechanisms.
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
This solution provides a uniform and customized light therapy, effectively addressing the issues of nonuniform irradiation and eye protection, enhancing the effectiveness of LED light treatment for facial skin while minimizing side effects.
Implementation Method 1
optical design for uniform irradiation is insufficient. There occurs a case in which more light than necessary is radiated to a specific region due to overlapping of light sources or the amount of light that is radiated is insufficient due to a large distance between the light sources. In addition, there occurs a problem in which the distance between the light source and the skin is not uniform, and therefore the amount of light that reaches the skin by light diffusion is not uniform.
Implementation Method 2
Light irradiation therapy, which uses various light sources, such as sunlight, laser, fluorescent lamps, UV, and LEDs, is performed based on the principle by which light accelerates biochemical reaction in the skin.
