    • A fluorescent lamp includes an arc tube 12 comprised of light transmissive material. The arc tube can be for a compact fluorescent lamp (CFL). A discharge sustaining fill 14, which may include mercury and an inert gas, is sealed in the interior of the arc tube. Electrodes are disposed in the sealed interior of the arc tube. An outer envelope 22 is disposed around and spaced apart from the arc tube. The outer envelope can take the form of a conventional incandescent light bulb, candle, globe-shape or reflector shape. The outer envelope includes an opening 24. The arc tube includes a hollow protrusion 26 that extends adjacent or into the opening. This can provide the arc tube with a lower temperature near the protrusion that can approximate the temperature of the outer envelope (a cold spot). This can regulate the vapor pressure of liquid (e.g., liquid mercury) in the arc tube.
    • 荧光灯包括由透光材料构成的电弧管12。 电弧管可用于紧凑型荧光灯(CFL)。 可以包括汞和惰性气体的放电维持填充物14密封在电弧管的内部。 电极设置在电弧管的密封内部。 外壳22设置在电弧管周围并与电弧管间隔开。 外壳可以采用常规白炽灯泡,蜡烛,球形或反射镜的形式。 外壳包括开口24.电弧管包括相邻或开口延伸的中空突起26。 这可以使电弧管在突起附近具有较低的温度,其可以接近外壳的温度(冷点)。 这可以调节电弧管中的液体(例如液态汞)的蒸气压。
