Latent water sterilization lamp of capacitive start type

The utility model discloses a latent water sterilization lamp of capacitive start type, including sleeve pipe and the sealed head of gluing, the intraductal ultraviolet tube of being equipped with of cover, the one end that is equipped with filament work electric capacity, ultraviolet tube that connects in parallel between the filament of ultraviolet tube's both ends are connected with start -up electric capacity, start -up capacitance parallel connection is provided with discharge resistance, and the other end that starts electric capacity and ultraviolet tube is connected with input voltage, and among utilization start -up electric capacity and the fluorescent tube current circuit, the metering function of start -up electric capacity can provide a steady job state for the fluorescent tube. And and common fluorescence lamp inductance starts or electronic ballast starting drive compares owing to start electric capacity, and its resistance value is much little, therefore the during operation generates heat har
