Investigation on the Modeling and Ageing Characteristics of the HID Car Headlight Automotive System


Article Preview

In this study, ageing effect for xenon through experiment has been studied. The study focuses on the modeling, ageing characteristics of xenon car headlight. The modeling of the lamp is based on spline interpolation algorithms. In this model, the voltage drop at the electrodes is considered as the aging factor. Ageing characteristics under the flicker condition for 4 types of xenon car headlight lamps have been measured. The flicker time is 4 seconds turn on and 2 seconds turn off, and the total testing time is 48 hours. The luminous, voltage and current of the lamp are measured. It is found that even a short period of flicker significantly affects the life time of the lamp.
