Seoul Viosys And SETi To Commercialise LEDs Used By NASA

Companies take next step to push deep UV technology into mainstream

Korean UV LED company, Seoul Viosys, and US based short-wavelength UV LED maker Sensor Electronics Technology Inc (SETi) have signed an agreement to jointly commercialise and expand related sales of the Violeds technology which NASA uses on board the International Space Station (ISS).

The Violeds technology on the ISS uses a UV-C wavelength (a subset of UV covering 100 to 290nm wavelengths) ideal for sterilization. The technology facilitates various experimental and sterile environments in the sealed space station and ensures experiment validity and crewmember safety.

Seoul Viosys recently secured the executive management share of SETi, after ten years of investing in SETi and jointly developing UV LED chips with wavelengths below 350nm.

Many products such as mobile phones, washing machines, refrigerators, vacuum cleaners, and air-conditioners harbour bacteria and yet they cannot be sterilized by conventional cleaning chemicals. For these products and many more, UV technology is considered an environmental friendly, low power  and compact approach. 

Emmanuel Lakios, CEO of SETi, said that he expects the Violeds technology to be applicable to household appliances, automotive air conditioning, and many more uses.

Jaejo Kim, CEO of Seoul Viosys commented: "Violeds technology applied to the use in the space station for disinfection is a very good example of "Creative Economy" where a novel technology will contribute to increased employment and to the growth of the national economy as well."

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
