Behaviour of the Cathode Active Surface Temperature in the Steady-State Diffuse Mode of HID Lamps

Abstract

Generally, the topics of functioning model of high intensity discharge (HID) lamp electrode presents a big scientific interest. A lot of lamp properties and lamp efficient functioning are in strong relationship with the cathode operation. The non-linear equation of heat transfer influence the electronic emission mechanism (Schottky amplified thermionic emission, thermofield emission or field emission). Many authors developed theoretical model in order to calculate the electrode temperature distribution 1, 2, the arc attachment modes or the transition between different mode 3. In this paper we analyze, in the case of diffuse cathode mode functioning, the influence of some external parameters on the cathode active surface temperature.
