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 working atmosphere are the key factors that affect the luminous efficiency and service life of electrodeless lamp. Induction lamp exhaust equipment is still followed the ordinary glass system exhaust equipment. As a result, the product quality of the lamp produced domestically is not stable enough. In particular, there is a certain gap between foreign products and the consistency of the parameters and the luminous efficiency, so that its advantages can not be fully exerted. In this paper, starting from the process of electrodeless lamp, the structure design of induction lamp exhaust station is discussed in detail from several aspects, such as vacuum system, baking system, charging and working gas recovery.
