UV LED Solutions for Medical & Sterilization — Advanced LED Solutions for Industrial Applications

Application Overview

QUEENDOM’s UV LED portfolio addresses the growing demand for chemical-free disinfection across healthcare, food processing, water treatment, and public space applications. Unlike mercury vapor UV lamps that contain toxic heavy metals and require warm-up time, our UV LEDs provide instant-on, wavelength-precise ultraviolet emission without hazardous materials or glass fragility. The portfolio spans UVA (315-400nm) for curing and phototherapy, UVB (280-315nm) for medical treatments and vitamin D synthesis, and UVC (100-280nm) for germicidal applications including the emerging 222nm far-UVC technology that inactivates pathogens while remaining safe for human exposure. For medical sterilization, our 275nm UVC LEDs achieve >99.9% bacterial and viral inactivation (including SARS-CoV-2) with doses of 10-50 mJ/cm², enabling rapid surface disinfection in hospital rooms, ambulances, and medical device manufacturing cleanrooms. The 222nm far-UVC technology represents a breakthrough for occupied-space disinfection — research from Columbia University and Kobe University demonstrates that 222nm light is absorbed by the outer dead layer of skin and tear film, preventing retinal and dermal damage while maintaining germicidal efficacy against airborne pathogens. Our UV LED packages incorporate specialized quartz or high-purity aluminum nitride windows that transmit UV wavelengths while blocking visible light emission.

Application Cases

UVC LED Air Purification in Hospital Wards

A 500-bed hospital in Germany installed UVC LED air purification systems using our 275nm devices in 120 patient rooms and surgical wards. The ceiling-mounted units provided 5 air changes per hour with >99.97% airborne pathogen reduction, contributing to a 42% decrease in hospital-acquired infections over 18 months. The LED-based system eliminated the ozone generation and mercury disposal concerns of conventional UV systems. Operational cost was 60% lower than HEPA filtration at equivalent air change rates.

Far-UVC 222nm Occupied Space Disinfection

A major international airport deployed our 222nm far-UVC LED arrays in passenger boarding bridges and security screening areas. The continuous operation during passenger occupancy maintained >95% airborne bacteria reduction without requiring evacuation protocols. Independent photobiological safety testing confirmed RG0 (exempt) classification per IEC 62471. The installation supported 24/7 operations with 50,000-hour LED lifespan and minimal maintenance requirements compared to mercury lamp replacement schedules.
