Emits shortwave ultraviolet light (270-280 nm) that inactivates microorganisms by damaging their DNA/RNA. In practical UVC LED applications, wavelengths between 260 and 280 nm are most commonly used, as they offer the highest germicidal efficiency. The most effective wavelength for DNA and RNA absorption is around 265 nm.
The technology is chemical-free, energy-efficient, and suitable for a wide range of applications:
- Air purification: Eliminates airborne pathogens in ventilation systems and air purifiers.
- Water treatment: Enables rapid disinfection without chemicals, from portable to industrial systems.
- Surface disinfection: Contactless cleaning of sensitive surfaces and equipment.
- Medical sterilization: Gentle treatment of instruments in healthcare environments.
- Food processing: Disinfects surfaces and packaging without affecting product quality.
Warning: Ultraviolet radiation can cause serious damage to skin and eyes. Under certain conditions, UV radiation may generate ozone, a gas harmful to the lungs. When working with or developing UV-based products, appropriate protective equipment must be used, including UV-blocking safety goggles.
About UV radiation:
UV radiation is divided into three main regions: UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm). Each has different biological effects and potential health risks. UVA penetrates deep into the skin and contributes to premature aging. UVB is more energetic and can cause skin and eye damage, including burns. UVC is the most energetic form of UV radiation and is highly effective for disinfection, but also the most harmful to biological tissue. UVC is normally absorbed by the Earth's atmosphere and does not occur naturally at ground level.
