1. a light-emitting diodes tube protective circuit is characterized in that, comprising:

  • One light-emitting diode (LED) module;

    Two electrical fuse elements connect this light-emitting diode (LED) module respectively, during flowing through electric current and surpass a protective current value on this electrical fuse element, are to present open-circuit condition, flow through this light-emitting diode (LED) module to cut off a big electric current;

    AndOne discharge prevention element is to connect this light-emitting diode (LED) module, this two electrical fuse element, and this discharge prevention element provides a current bypass path of this light-emitting diode (LED) module.
