A mathematical model for the starting process of discharge lamps

摘要

References(12) 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 with the mathematical model for the starting process of discharge lamps. Newly introducing the concept of heat quantity, the authors were able to produce a mathematical model to represent the starting process of the low pressure sodium lamp. In this paper, the following comparison between the theoretical results using this model and experimental results on the low pressure sodium lamp are discussed.(1) Lamp voltage and current waveforms in the starting process.(2) Evaluation whether or not the lamp can get to operating state.These investigations showed that this model is available for representing the starting process of the low pressure sodium lamp.
