Solution Overview
Problem
Conventional UV LED-based sterilization devices face challenges in maintaining internal volume and efficiency due to the need for additional space for UV LEDs and electronic components, which reduces product capacity and UV light transmittance.
Innovation Solution
A multifunction LED lighting apparatus with UV LEDs and lighting LEDs integrated on a substrate, forming a single module, where the UV LEDs radiate ultraviolet rays directly to the interior and are optionally exposed through a cover with a photocatalyst, allowing for increased internal volume and enhanced sterilization and deodorization functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional UV LED sterilization device is installed, then sterilization function is provided, but internal volume of the product is reduced due to additional space required for UV LED and electronic components
Solution Approach 1:
The patent combines the UV LED sterilization module with the existing lighting module into a single integrated structure. The UV LED is mounted on the same substrate as the lighting LED, eliminating the need for separate installation space. This merging of functions directly resolves the contradiction by maintaining sterilization capability while preserving internal volume.
Solution Approach 2:
The lighting module is designed to serve multiple functions: general illumination and UV sterilization. By making the lighting module universal, the patent eliminates the need for a dedicated separate sterilization device, thereby maintaining the product's internal volume while providing both lighting and sterilization functions.
2Reliability
If a conventional UV LED sterilization device is installed, then sterilization function is provided, but UV light transmittance is deteriorated due to components added between UV light source and subject
Solution Approach 1:
The patent extracts the UV LED directly to the front surface of the lighting module, removing intermediate components that would block or attenuate UV light. By taking out the UV light source to a position with minimal obstructions, the patent maximizes UV transmittance to the subject while maintaining sterilization effectiveness.
Solution Approach 2:
The patent introduces a UV-transparent window or cover as an intermediary component that allows UV light to pass through while providing necessary protection and structural integrity. This mediator maintains UV light transmittance while enabling the device to function properly.
