Abstract

The invention concerns a lamp, for instance a mercury UV lamp, comprising, at each of its ends, an electrode chamber (6), whereof the internal diameter is larger than that of a longitudinal transmitter tube (1) with which it communicates. The output zone of the electrode chamber is spherical, it centre of curvature (C) being arranged on a front zone, covered by a filament (3b), a support rod (4) of an electrode (2) housed in the electrode chamber. The infrared rays (Ri) transmitted by one exposed front end of the support rod are reflected (Rr) towards the rear of the electrode by a reflecting material (7) covering the chamber. Additionally, the flow rate of the air cooling the tube (1) is modulated proportionally to the electric voltage at the lamp terminals. In case of temporary pause of the installation, this ensures uniform and longitudinal condensation of mercury in the tube (1), without formation of mercury droplets in the electrode chambers.
