This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,689.

Summary of the Inventive Concept

Improved flexible UV light generation systems with enhanced flexibility, uniformity, safety, durability, and adjustability for efficient and effective UV light emission.

Background and Problem Solved

The original patent disclosed a flexible UV light generation system, but it had limitations in terms of flexibility, UV light emission uniformity, safety, durability, and adjustability. The new inventive concept addresses these limitations by introducing novel design and material enhancements.

Detailed Description of the Inventive Concept

The enhanced flexible UV light generation system features a flexible circuit with multiple UV-LEDs arranged in a spiral pattern, improving flexibility and reducing stress concentrations. The system also includes a UV diffuse reflective layer with a textured surface, enhancing UV light emission uniformity. Additionally, the system incorporates a built-in UV sensor to detect and respond to excessive UV radiation, ensuring safety. The UV diffuse reflective layer is coated with a protective layer to prevent degradation from environmental factors, improving durability. Furthermore, the system features a variable reflectivity mechanism to adjust the UV intensity output, providing adjustability. These enhancements result in a more efficient and effective UV light generation system.

Novelty and Inventive Step

The new claims introduce novel design and material enhancements that improve flexibility, uniformity, safety, durability, and adjustability, making the inventive concept non-obvious and distinct from the original patent.

Alternative Embodiments and Variations
