在全密封反射荧光灯的燃点过程中,玻管管壁温度有时高达170℃,在此情况下,如果使用液汞,放电管内由于汞蒸气压升高,灯的光通量就会骤然下降,为了把汞蒸气压控制在规定的0.8Pa范围内,一般是使用BiInHg高温汞齐代替液汞,将放电管内的汞蒸气压控制在希望值之内。BiInHg高温汞齐的
In the fully sealed reflective fluorescent lamp ignition process, the glass tube wall temperature sometimes up to 170 ℃, in this case, if the use of liquid mercury, discharge tube due to mercury vapor pressure increases, the light flux of the lamp will suddenly drop, in order to mercury Vapor pressure control in the specified 0.8Pa range, the general is to use high-temperature mercury BiInHg instead of liquid mercury, the mercury vapor pressure within the discharge tube control within the desired value. BiInHg high temperature amalgam
