HID灯和电子镇流器间的接口设计及镇流器可靠性研究

HID电光源在不断发展中,发展目标是追求更高的光效、更大的显色指数、更高的流明维持率和更长的使用寿命,而设计良好的电子镇流器可以帮助HID电光源朝这个目标不断迈进。在设计阶段,评估HID电子镇流器性能好坏的指标有许多,其中两点尤其关键,分别是同HID电光源的匹配性(LDI),和镇流器自身的可靠性。本文将首先简单介绍HID电光源的发展,然后根据HID灯的工作特性,列出主要的LDI指标要求,再探讨如何在HID电子镇流器中来实现这些LDI指标和提高自身的可靠性。最后介绍电子镇流器同HID灯接口性能的测试方法。

HID Lamps and Electronic Ballasts Interface Design and Reliability Investigation

Higher lumen efficacy, larger colour rendering index, higher lumen maintenance and longer lifetime are the major pursuit targets during HID lamps performance development, and those targets are facilitated with the aid of finely designed electronic ballasts. During the design phase, many items are determined to evaluate the ballasts＇ performance, among which two points are of the most importance, namely HID lamps-ballasts interface （LDI） and ballasts＇ reliability. In this paper, the development of HID lamps are firstly reviewed, and then based on the characteristics of HID lamps, major items of LDI are elaborated, and LDI design reliability investigation in ballasts are explained. Finally, experimental measures are introduced to test LDI performance.
