摘　　要：光谱灯的小型化是谱灯抽运被动型铷原子频标小型化的关键之一。分别对光谱灯的机械结构、热结构、电磁结构和电路结构进行了分析、仿真和优化,并改进设计了一种小型化的铷光谱灯,经过测试取得了比较理想的结果,其主要性能指标如下:体积<14 mL,灯温<115℃,激励电流<80 mA,光漂移<1.10-4/d,光温度系数<1.10-3/℃。此小型化的铷光应谱灯已应用于小型化铷原子频标中。The downsized spectrum lamp is one of the key points of the miniature passive Rubidium Frequency Standards（RFS）. As a complex compound, the lamp is divided into four aspects which include mechanical structure, thermal distribution, electromagnetic radiation and exciting circuit scheme. Accord- ing to the result of compute simulation and parameters optimization a downsized lamp is designed and result in good performance as followed： volume 〈 14mL, lamp temperature 〈 115 ℃ , exciting current 〈 80 mA, light drift 〈 1 . 10^-4/day,light sensitivity 〈 1 . 10^-3/℃. This downsized spectrum lamp have been used successfully in the miniature RFSo
