Toyoda Gosei: LED light source, kill bacteria: UV wavelength less than 280nm
【Nagoya】
Toyoda Gosei:
July 22, announced that it has developed a “Deep-UV light emitting diode (LED) light source module that can inactivate viruses and kill bacteria.”
LED light source module:
You can inactivate new coronaviruses, sterilize water, air, surface of objects, etc.
We aim to start mass production within 2020.
Application fields:
public facility,
restaurant,
Car cabin space,
It is expected to be adopted.
Short UV wavelength:
UV wavelength less than 280nm destroys viral genes and suppresses proliferation.
4 cm in size, with waterproof and heat dissipation functions,
Easy to attach to the device, the shape of the module can be changed,
Test results using human coronavirus:
Conducted a test using the human coronavirus, which has a gene similar to the new corona.
We were able to inactivate 99.9% of the virus within 10 seconds of irradiating with light.
New switch
Toyoda Gosei Develops Deep UV LED Light Module for Sterilization
Kiyosu, Japan, July 22, 2020:
Toyoda Gosei Co., Ltd.
has developed a deep UV LED light module for use in the sterilization of water, air, and surfaces.
These new modules
take advantage of the technology that the company has accumulated over 30 years in the development and production of blue LEDs.
Deep UV LEDs
emit short wavelength ultraviolet light that can destroy the genetic materials of viruses and bacteria.
They are promising as a new sterilizing light source that can be used in place of mercury lamps, for which there is environmental concern.
With the aim of spreading applications of this technology,Toyoda Gosei
has been developing products in modules or units with waterproof or heat dissipation features.
In a joint experiment conducted with the Biomedical Science Association* using human coronavirus 229E (HCoV-229E), which has genetic materials similar to those of the virus that causes Covid-19 (SARS-CoV2), these modules were demonstrated to be highly effective in sterilization.
Toyoda Gosei
is cooperating with the Toyota Group and other companies to develop applications for water, air and surface sterilization that contribute to safer and healthier living.
The company
will continue to contribute to the creation of a sustainable society through the core technologies it has cultivated.
