Multi-Band UV LED Package Structure With Visible Warning Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultraviolet disinfection lamps often have a single band that cannot be adjusted, making them ineffective for different types of germs and items, as various germs require different UV bands for killing and items have varying UV requirements for sterilization and disinfection.
Innovation Solution
An LED package structure that includes multiple ultraviolet-band LED wafers (UVA, UVB, UVC) and a visible light-band LED wafer, each connected to a control unit to adjust light emission and intensity, allowing for customizable disinfection and illumination/warning functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-band ultraviolet disinfection lamp is used, then the structure is simple, but it cannot meet the disinfection requirements of different germs and items
Solution Approach 1:
The patent combines multiple ultraviolet LED wafers of different bands (UVA, UVB, UVC) and visible light LED wafers into a single integrated lamp head assembly. This merging approach enables one lamp to provide multiple disinfection bands and illumination functions simultaneously, resolving the contradiction between versatility and structural complexity
Solution Approach 2:
The lamp head is designed as a universal platform that can perform multiple functions: UVA for penetration disinfection, UVB for surface disinfection, UVC for germicidal disinfection, and visible light for illumination and warning. This multi-functional design allows a single device to adapt to various disinfection scenarios without requiring separate specialized lamps
2Adaptability or versatility
If multiple ultraviolet-band LED wafers are integrated into one lamp, then disinfection versatility is improved, but the lamp occupies more space
Solution Approach 1:
The patent employs a nested arrangement where multiple LED wafers of different bands are closely integrated within a single lamp head structure. The wafers are arranged in a compact configuration that maximizes space utilization, allowing UVA, UVB, UVC, and visible light wafers to coexist in a unified housing without excessive volume increase
3Reliability
If conventional single-band ultraviolet lamps are used, then the structure is compact, but safety indication is lacking
Solution Approach 1:
The visible light LED wafers serve dual purposes: providing illumination during disinfection operations and emitting warning light to alert people of active UV disinfection. This multi-functionality enhances safety without requiring separate indication devices, maintaining compactness while improving reliability

AI summary
An LED package structure, and a disinfection device and a disinfection lamp applying same. The LED package structure comprises: an LED wafer unit comprising a plurality of ultraviolet-band LED wafers and a visible light-band LED wafer. Each of the LED wafers is externally connected to a control unit for controlling whether each ultraviolet-band LED wafer emits light or not and a light emission intensity to emit light of different disinfecting bands and disinfecting effects as required, and controlling the visible light-band LED wafer to emit illumination and/or warning light, thereby achieving a technical effect of multiple purposes in one lamp. Meanwhile, the present disclosure can meet various disinfection requirements by using one product structure, and therefore, compared with conventional single-function disinfection lamps, the present disclosure has a more compact structure to occupy a smaller space, and has an indication function to improve safety of ultraviolet disinfection.
