## 5 Conclusions
One of the solutions may be the implementation of controlling the current of UVC LEDs in a system with a feedback loop containing a control module of optical power, similar to the stabilization of the optical power of semiconductor lasers. However, a gradual increase in the supply current may lead to a decrease in the lifetime of UVC LEDs.
