【摘要】 微波硫灯具有高效节能（η＞９０１ｍ／Ｗ）、长寿命（ｆ≥６×１０４ｈ）、显色指数高（Ｒａ≥７９）、较低的红外、紫外输出、无汞害污染等诸多优点，它在九十年代初一问世就受到国际上照明界的关注和重视。本文试从硫分子（Ｓ２）的放电辐射光谱的Ｘ３Σｇ－Ｂ３Σｕ跃迁出发，分析解释新颖节能微波硫灯适合用于照明领域的内在原因；并根据气体放电的基本理论，给出定量计算其光谱的方法更多还原

【Abstract】 A novel high efficacy light source powered by microwave energy has been discovered for several years.Due to it’s advantages,such as high efficacy( η> 90lm/W),long life( l≥ 6×10 4h),good colour rendering index( Ra ≥79),low infrared and ultraviolet radiation,etc.it has been considered as the useful energy saving lamp in the near future.The plasma forming medium of these lamps is high purity sulfur which emittes strong light by the molecular radiation at high pressure.The spectrum structure of S 2 has been analyzed and an approach to simulate and calculate the visible spectrum of microwave sulfur lamp is given out in the paper.更多还原
