Several mathematical models for discharge lamps have already been offered . However, all these models are only used for the operating state. There are not any models for the starting process . This paper is concerned in the mathematical models for the starting process of discharge lamps . Newly introducing the concept of thermal quantity, the authors could have the mathematical model to represent the starting process of the low pressure sodium lamp. In this paper, the following comparison between the theoretical results by this model and experimental results on the low pressure sodium lamp is discussed. (1) The lamp voltage and current waveforms in the starting process (2) The judgment whether the lamp can get to the operating state or not These investigations showed that this model is available for representing the starting process of the low pressure sodium lamp.

A mathematical model for the starting process of discharge lamps.
