ABSTRACT:
To cool the diaphragm of a spectral discharge lamp having an anode and a cathode between which a discharge is established, which discharge is controlled by the diaphragm, a fluid supply and removal duct is connected to a cooling circuit in or on the diaphragm structure to supply, for example, water to cool the diaphragm. The tube or bulb of the lamp may be in form of a jacketed enclosure through which cooling water is conducted, preferably in the same supply and removal circuit as that for the diaphragm structure.
