1993年 ,在汉诺威工业展上 ,有公司推出世界第一只无汞钠 -氙灯 ,功率约 80Ｗ。该灯通过专用电子镇流器供给灯脉冲电流。本文特别评述了高压钠灯在脉冲状态的工作特性。多位研究者发现 ,脉冲状态工作时 ,等离子体的温度 (ＴПЛ) ,随电流脉冲增大而上升 ,甚至可达到出乎意外的
In 1993, at the Hanover Industrial Fair, a company introduced the world’s first mercury-free sodium-xenon lamp with a power of about 80W. The lamp supplies the lamp pulse current through a dedicated electronic ballast. This article reviews in particular the operating characteristics of HPS lamps under pulsed conditions. Several investigators have found that the plasma temperature (TПЛ), which rises with the increase of the current pulse, can reach an even unexpected result
