UV LEDs cover a wide range of applications including light curing, medical treatment and disinfection. And now, UV LEDs are put on drones to spew UV light in subway stations and trains for sanitization.


An online magazine, Yanko Design, reported that Korean designers at Off Garage Studio created a UV LED integrated drone as a “space care system,” providing autonomous sterilization service. Equipped with sensors and UVC LEDs, the drone is designed to flies smoothly around the station and emits UV LED light in the subways to efficiently and effectively clean the germs on surfaces as well as purify the air.

Apart from UVC LED, the drone has a front vision sensor, a driving camera, a bottom vision sensor, a side vision sensor and an ultrasonic sensor to ensure that its flight safety. In addition, it also installed with front LEDs and bottom LEDs that light up in the dark. When the stations close, the drone can float around to provide thorough hygienic services.

The designers call the drone “GHOST,” addressing its white color and light design. The products would help to cut down extra cleaning hours and enhance hygiene in public transportation.

In LEDinside's latest report, titled “2019 Deep UV LED Application Market- Sterilization, Purification, and Water Treatment Markets,” it was noted that UV LED market continues to increase with driving momentum from applications in sterilization for surface, air, static and flowing water. The UV LED market value is forecasted to reach US$ 991 million in 2023.
