Characteristics of fluorescent tube lamps work Lamps began to light requires a high voltage, the normal light allows only small current when the voltage of the tube ends below the supply voltage. This high-voltage jump from what we usually bubble (starter). , Due to two pieces of metal in the starter neon bulb is not connected to power, the power breakdown neon conductivity, then we see the neon bulb glow, neon conductive when the heat caused the bimetallic strip within the neon bulb (that is, we see the bending of the Okanagan) curvature after heat down, and connected to two electrodes, larger current. Fluorescent lamp to start the requirements of high voltage. After longer conductive bimetallic strip connected to the neon bulb neon light, the temperature fell rapidly, the bimetal restitution, and quickly cut off the power current of the ballast from the larger value suddenly becomes O, high self-inductance electromotive force, the self-inductance voltage is sufficient to breakdown of mercury vapor fluorescent lamps, mercury vapor ionization generated by electricity ultraviolet excited light-emitting phosphors, fluorescent tubes, conductive, fluorescent tubes at both ends of the voltage drop (100V or so), this voltage can no longer make the breakdown voltage of neon bulb conductive (neon bulb is about 150V) and luminous, the bimetallic strip is no longer connected, then the fluorescent lamp will be able to continuous light.
