Prediction of HID lamp considering P-1 radiation model

Summary form only given, as follows. HID (high intensity discharge) lamps are used in many disciplines including biotechnologies, electronics and telecommunications. Rapid design and development are of key importance in order to shorten the time for a new design to reach the market. Numerical simulation is a cost and time effective solution for fast development. In this paper, we describe a robust simulation package that can be useful in many types of HID lamp designs. The full simulation package consists of several segments to model the electrodes, plasma and glass bulb. Due to space limitations, we focus on the plasma model. The numerical simulation is done for a 2-D axisymmetric geometry assuming that the anode is at the top of the vertically oriented lamp and that the discharge medium is a mercury-argon (10:1 molar concentration ratio) mixture operating at 1.1 atm.
