Abstract
A protective pipe for a UV lamp for accommodating a tube includes a rod-shaped encasing pipe, wherein a viewing window is provided on the circumferential surface, through which viewing window the radiation, in particular the UV-C radiation, emitted by the tube can escape. A coating made of polytetrafluoroethylene is applied to the inner face of the protective pipe as a reflector. The protective pipe is composed of metal and is surrounded, at least in the region of the viewing window, by an at least partially transparent hose composed of plastic. Preferably, a transparent Teflon material is proposed for the hose.
