摘　　要：介绍了研发小功率陶瓷金卤灯需要解决的关键技术问题,包括用Dy2O3-Al2O3-SiO2焊料体系解决铌与陶瓷毛细管的匹配封接,控制焊料渗漏和腐蚀,在电弧管中充入放射性气体85Kr解决启动问题;采用X光透视、红外热成像、X光断层扫描和扫描电镜等手段诊断和优化产品性能,实现了20W、35W、70W、150W四种小功率陶瓷金卤灯的产业化,产品性能全面优于国标规定值,功率70W、色温3 000K的陶瓷金卤灯的光效为89 lm/W,显色指数92,8 000h光通维持率为82%。This paper introduces the key technologies of low wattage ceramic metal halide lamps（CMHs）,which include sovling the matched-sealing of Nb and the ceramic capillary with Dy2O3-Al2O3-SiO2 frit system,controlling frit leakage and corrosion,solving the ignition problem with radioactive gas 85Kr filling in the arc tubes.In order to optimize the parameters of CMHs,some diagnostic methods were used,such as X-ray transmission,infrared imaging,X-ray tomography,and scanning electron microscope.The CMHs with power of 20,35,70 and 150W have been put into mass production,whose parameters are better than those in the national standard.The CMHs with 70W power and 3,000K color temperature have luminous efficacy 89 lm/W,color rendering 92,lumen maintenance 82% at 8,000h.
