AlGaN-based Far-UVC LED neither emits hazardous gas nor CO², which is unsafe to humans and environment. Therefore, UV LED is undoubtedly clean and safe compared to Hg-UV Lamps or Excimer Lamp. Hg-UV Lamps or Excimer Lamp can contribute to global warming and is hazardous to the environment as per WHO recommendation, 17 SDGs, and Minamata Convention of 2020.

Due to the low power consumption, UV LED technology is highly energy efficient. Due to the energy-saving feature, it can help in mitigating climate change, and it can suppress the energy crises.

Our technology of AlGaN Far-UVC LED grown on low-cost AlN template on a c-Sapphire substrate is quite economical compared to other Far-UVC LED technologies grown on expensive single-crystal AlN substrate. UV LED is also economical compared to Hg-UV Lamps or Excimer Lamps.

Finger-sized, lightweight LED comes very handy with no space constraints and makes it easier to carry out or install anywhere. Easy to use while keeping the surrounding environment clean and safe.

Impact-resistant, and therefore easy to handle, use and install safely.

As the lifespan of a product goes in proximity with its efficiency, and our recent works have given better results. The lifetimes of Hg-Lamp and LED (today), respectively, are 2 - 10 Khrs and 10 Khrs. The lifetimes of LED in 2030 are expected to be 25+ Khrs by improving both the crystal quality and packaging technologies of LED via a better heat sink.

Undoubtedly reliable, as the semiconductor is designed in a way to emit a particular wavelength, which is safe to humans as well as to the environment. The spectral emission wavelength in the range of 220-230 nm has been proven to be less harmful to the human eyes and body. Also, the materials used in the crystal growth and fabrications of the Far-UVC LED technologies are clean and environmentally safe.

◎: Very superior, 〇: Excellent, △: Needs improvement, ×: Very inferior

An irradiation test will be demonstrated, using Far-UVC LED to find the effect of ultraviolet rays in the range of 220nm to 230nm on viruses and germs.Under the joint research with Nihon University School of Medicine, the demonstration of inactivation of emerging coronavirus (SARS-CoV-2) is to be conducted. Livestock virus inactivation will be demonstrated, under the joint research with the Tokyo University of Agriculture and Technology.

In 2020, we were the first group to demonstrate the damage of viral RNA caused by UV Irradiation of wavelength 253.7 nm, resulting in the demonstration of SARS-CoV-2 Coronavirus inactivation.

The Far-UVC LED, which is currently under development, is yet to confirm its irradiation effects for the inactivation of germs and viruses, including SARS-CoV-2 (Coronavirus).We are also preparing a study to investigate its effects on the skin of the human body. Thereby, we guaranty the inactivation of germs with no compromise on the safety and well-being of other living bodies, including humans. We will also be performing the irradiation test by Far-UVC LED to confirm the inactivation of viruses such as adenovirus, poliovirus, rotavirus, hepatitis A virus, feline calicivirus, coxsackievirus, phage, and influenza virus.

We will be the first to realize the social implementation of virus-inactivating devices that can be used, even in spaces occupied with human beings and animals.
