摘　　要：稳定的本底真空度和良好的工作气体氛围是影响无极灯的发光效率和使用寿命的关键因素。国内无极灯的排气设备还是沿用了普通玻璃系统的排气设备。这导致国内生产的无极灯在运行中产品质量不够稳定,尤其在参数的一致性和发光效率方面与国外产品存着一定的差距,从而使得其优势无法完全发挥出来。本文从无极灯的工艺出发,从真空系统、烘烤系统、充气和工作气体回收等几个方面详细讨论了无极灯排气台的结构设计。Stable background vacuum and good gas atmosphere are both the key influencing factors on the luminescent efficiency and service life of electrodeless discharge lamp. In China the exhaust units are still used continuously for ordinary glass without special ones, thus resulting in that the quality of domestic electrodless discharge lemps is unstable in running especially the poorer luminescent efficiency and parametric consistency in comparison with the foreign products. Therefore, it is unable to take fully the advantages of electrodeless discharge lamps. For this reason, the constructional design of the exhanst unit for such lamps is discussed in detail, taking a rigorous view of the technological process, vacuum system, baking system and working gas charging/recycling.
