Abstract

A disinfecting lamp having one or more diodes emitting UV-C light (LEDs) is described, in which the bandgap from the valence band to the conduction band is set to 4.5 to 4.9 eV, and preferably to 4.7 eV, by the mixture ratio of the semiconductor compounds in the diode, as a result of which the wavelength of the light emitted is between 250 and 280 nm, and is preferably 265 nm, and the light thus has an optimum germicidal action.
