摘要

This report describes the design and main technical characteristics of an LED device with a programmable UV spectrum in the range 250–400 nm. The device is intended for biomedical applications. The device developed here was used to assess the bactericidal efficiency of different UV wavelengths against multiresistant strains of Klebsiella pneumoniae. Short-wave LEDs emitting in the range of 250–300 nm were found to be more effective in inactivating Klebsiella strains than low-pressure mercury lamps.
