Compensation and lamp life model of HID lamp

Abstract

This paper is to find out the alternative method to compensate a Xenon lamp near the end of its life time. In the past, the lamp will be disposed if an effective intensity cannot be obtained. The proposed study is to provide a compensation method that, based on the measured characteristics of general Xenon lamps, and to calculate the required compensation power and to extend the constant illumination time. The method call the constant illumination of the light output even under the aging of the lamp. The method can effectively extend the effective life time of an Xenon lamp.
