Abstract (en)

The use of certain wavelengths of ultraviolet radiation in particular UV-C light for its purification, germicidal and bactericidal effect is well known. The invention relates to an improved discharge lamp for disinfecting a medium, comprising means (4) for covering a cold sport region of the discharge vessel (2) of the lamp. Thus the temperature of the cold spot can be held sufficiently high to secure an improved light output, substantially independent from the temperature of a surrounding medium to be disinfected.
