Ultraviolet ray LEDs of short wavelength have been developed, and recently also sold, though blue LEDs had been sold before. Therefore, their application to various industries such as a medical treatment, biotechnology, clean air, and resin stiffening is expected, and there are growing needs to make devices for trial purposes using ultraviolet rays LED and to evaluate their performance. Thus we aimed to examine the characteristics, longevity, drive system etc. for marketed ultraviolet ray LEDs, and to make a drive circuit for basic research and evaluation for trial purposes that aids commercialization. Then,we report on our research which benefits research and products which apply ultraviolet ray LEDs.
