Cleaner water. Healthier air. Safer food. Disinfection with CrayoNano’s powerful UV-C LED technology can be used to improve people's lives.

CrayoNano's CrayoLED™ H-Series (CLH-N3S) is optimized for disinfection at a typical peak wavelength of 275 nm.

Its small package footprint (3.5 mm x 3.5 mm) and high-power performance of 100 mW at 350 mA. easily integrates into systems for residential, commercial, and industrial segments, enabling system miniaturization and longer lasting solutions for UV-C applications.

UV-C LEDs opens opportunities for a positive and sustainable social and environmental outcome.

UV-C radiation is a well-studied disinfectant used against bacteria, viruses, mold, and spores—commonly used in many disinfection, industrial, and commercial applications today. The power of UV-C to disinfect is through the breakdown of DNA and RNA when exposed to UV-C radiation, preventing microbes and other pathogens from replicating and inducing illness.

The demands of population density and resource scarcity call for novel strategies to automate disinfection processes in a manner that is efficient, resource-friendly, and cost-effective. UV-C LEDs enables new possibilities for applications that can have a significant positive impact on both society and the environment.

  • UV-C radiation wavelength range between 100–280 nm and is the shortest wavelength of the electromagnetic spectrum. It has a high energy radiation that is absorbed by DNA, RNA and proteins. UV-C radiation principal mode of microbial inactivation occurs when the absorption of a UV-C absorption by DNA or RNA, then forms pyrimidine dimers between adjacent thymine bases and renders the microbe incapable of replicating properly.

    It is important to note that UV-C radiation can also be harmful to humans and other living organisms, so precautions must be taken when using UV-C radiation. Exposure to high levels of UV-C radiation can cause skin and eye damage. Therefore, it is recommended to use UV-C radiation in a controlled and safe manner, wearing the proper safety equipment.
  • Mercury lamps have been commonly used for disinfection purposes, with a peak wavelength of 254 nm. However, with the availability of UV-C LEDs in the range of 250–280 nm, offer more available sources.

    Microbes have different sensitivities to UV-C, as shown by the virucidal efficiency action spectra curve. For example, E. coli is most sensitive to a peak wavelength of 265 nm, which is often referenced as the wavelength for optimal germicidal effectiveness.

    When choosing a wavelength for disinfection purposes, it's important to consider the trade-off between virucidal efficiency and output power. Shorter wavelength LEDs typically have lower output power, while longer wavelength LEDs, such as 275 nm, have higher output power. Although 275 nm may have lower virucidal efficiency, the higher output power and better wall plug efficiency can compensate for this. This is known as virucidal power, which is the normalization of wavelength dependency for virucidal efficiency and optical output power.
  • UV-C LEDs can contribute to sustainability in several ways. First, they use significantly less energy than traditional UV lamps, which can help reduce overall energy consumption. Additionally, UV-C LEDs have a much longer lifespan than traditional UV lamps, which means they need to be replaced less frequently and can reduce waste. They can also be used in air and water disinfection systems to help reduce the use of chemicals and other pollutants. Furthermore, UV-C LED lights do not contain mercury, which is a toxic substance found in traditional UV lamps that can be harmful to the environment if not disposed of properly.
