UVC led light
What is different of UV Light, UV-V light, UV-C light, UB-B light, UV-A light? UV light is in the spectrum of 100nm to 400nm. This is just below the visible light spectrum of 400-800nm. It is divided into 4 parts, UV-V at 100-200nm, UV-C at 200-280nm (for example call as 275nm uv led, 275nm led, uvc led, 265 nm uv led, 250 nm uv led, uv-c led, uv-c led 254nm, 254 nm uv led, 275 nm wavelength), UB-B at 280-315nm and UV-A nearest the visible portion at 315-400nm (in the UV-A spectrum, typically 370nm, This light be Called as black lights because the light cannot be seen and appears black).
UVC energy is a commonly used sterilization technology that has been shown to inactivate a wide range of pathogens (e.g. MRSA, C. diff, E. Coli and Pseudomonas). For many years, UV mercury lamps were considered the best choice. However, lamps have several limitations, including low activity at refrigeration temperatures, fragile construction, long warm-up time, risk of mercury exposure, and limited UV emittance at 254 nm. In comparison, UV light-emitting diodes (UV LEDs) can be configured to emit at ideal germicidal wavelengths and provide reliable on-demand disinfection without the limitations which hamper mercury lamps.
How Do UVC LEDs Disinfect Pathogens? UVC energy is absorbed by nucleic acids inside the RNA and DNA, resulting in covalent bonds which at the right dose can render the pathogen unable to reproduce and infect. The most effective germicidal wavelength occurs with a peak between 260 nm to 270 nm, the point at which DNA absorbs UV energy the most.
Are UVC LEDs Effective Against COVID-19 (Coronavirus)? Crystal IS initiated a study with Boston University's National Emerging Infectious Diseases Laboratories (NEIDL) to understand how SARS-CoV-2 responds to ultraviolet light across the emission range of Klaran UVC LEDs (260 nm to 270 nm) and at varying doses. Exposing the virus to a 5 mJ/cm2 dose of UVC light at 268 nm resulted in a 2.8 log reduction of the virus.
UV-C Light Kills Viruses but That Does Not Mean You Should Use Them. Because it has the problems when Using UV C Light is Home or Office Settings: UV-C light contains radiation that is harmful to humans. Even looking at UV-C light can cause pain or damage to the cornea of the eye. Human skin can also become irritated and damaged by it.
