Samsung Electronics has reduced the number of home appliances launching next year that it will apply ultraviolet (UV) LED on from its initial target, TheElec has learned.

In September, the company had planned to install UV LED on up to 20 to 30% of new home appliances launching in 2021. The move was planned in light of the COVID-19 pandemic.

But it has reduced the number of models that it will install UV LED on and instead will expand their application depending on market reactions, people familiar with the matter said.

Samsung has recently begun testing the installation of UV LED on its home appliances launching next year. Only one model per a product series is planned get UV LED.

The company was testing the application of UV-C (wavelengths of 250 to 280 nanometers) on a refrigerator, an air purifier, an AC, a washing machine and a cloth cleaner. 

Samsung will measure how effective the UV-C LED are in disinfection and deodorization.

The company currently has UV LED installed on its Bespoke refrigerator and AirDresser.

The change to a more conservative schedule in applying UV-C LED was due to difficulty in estimating market reaction and disinfection effectiveness, people familiar with the matter said.

A supplier that uses LED chips made by Seoul Viosys is supplying the modules for Samsung’s testing.

Samsung was also considering using UV lamps if UV-C LED’s effectiveness is less than expected.

UV-A (315nm to 380nm) with longer wavelength are used mostly in printed circuit board production. UV-B (280nm to 315nm) are used in bio and medical sectors.
