Major light-maker Ushio Inc. has recently launched an ultraviolet lamp that can kill the coronavirus without harming human health — the first of its kind in the world.

The Care 222 UV lamp, which Ushio developed together with Columbia University, is expected to be used for disinfection in spaces where people keep going in and out and the risk of contracting the deadly virus is high, such as on buses, trains and elevators and in offices, the company said.

UV lamps have been widely used as an effective means of sterilization, notably in the medical and food-processing industries. But conventional UV rays cannot be used in spaces where there are people, as they cause skin cancer and eye problems.
