UV LED Applications

UV LED Applications

Sterilization/Disinfection/Purification

Mainstream wavelength: UVC (200–285nm, peak 260–280nm)

Mechanism of action: Destroys microbial DNA/RNA, achieving highly efficient inactivation

Typical applications: Water treatment (flowing/static), air purification, surface/object disinfection, sterilization of medical devices/household appliances, air conditioning/fresh air systems

Curing / Photopolymerization / Photochemistry

Main Wavelength: UVA (365–420nm, main peak 385/395/405nm)

Mechanism of Action: Initiates photoinitiator polymerization, rapid curing

Typical Applications: UV adhesives/inks/coatings/resins curing, 3D printing, electronic packaging/PCB, dental/nail materials, optical/display panels

Sensing / Detection / Medical / Other

Mainstream Wavelengths: UVB (280–315nm) + UVA (315–365nm)

Mechanism of Action: Fluorescence excitation, photobiological reaction, analytical detection

Typical Applications: Fluorescence detection (counterfeit money/minerals/criminal crimes/material defects), phototherapy (skin diseases/vitamin D), plant growth induction, scientific instruments/analytical tools
