    • A mercury-free discharge lamp includes a hollow cylindrical body, two capillaries entirely inside the body and hermetically sealed to the body, each with a respective electrode therein, where the capillaries are separated from each other inside the body by a gap that is a discharge chamber of the discharge lamp, and where each of the electrodes has an interior end exposed inside the discharge chamber and an exterior end extending beyond a respective end of the body. A pair of frit seals seal respective electrode exterior ends to respective ones of the capillaries. The discharge chamber preferably includes a mercury-free metal halide salt fill that is 10 to 54.5 wt% NaI, 6.6 to 15 wt% DyI3, 6.7 to 15 wt% HoI3, 6.3 to 15 wt% TmI3, 7.2 to 12 wt % TlI, and 14.5 to 40.7 wt % CaI2.
    • 一种无汞放电灯包括一个空心圆柱体,两个毛细管完全位于主体内部并密封在主体上,每个毛细管内有一个相应的电极,毛细管在主体内部通过一个间隙排出 并且其中每个电极具有暴露在放电室内部的内部端部和延伸超过本体的相应端部的外部端部。 一对玻璃料密封件将各自的电极外端密封到各自的毛细管。 放电室优选包括无汞金属卤化物盐填充物,其含有10-54.5重量%的NaI,6.6-15重量%的DyI3,6.7-15重量%的HoI3,6.3-15重量%的TmI3,7.2-12重量%的TlI, 和14.5至40.7重量%的CaI 2。
