1. A light-emitting diode (LED) tube applied to a lamp holder with a ballast, the LED tube comprising:

  • a lighting module having;

    a first terminal;

    a second terminal opposite to the first terminal; and

    multiple LED elements;

    a first control module connected to the first terminal of the lighting module and having;

    a first simulation circuit unit having;

    a first capacitor;

    a first resistor parallelly connected to the first capacitor; and

    a first switching element connected in series to the parallel-connected first capacitor and first resistor; and

    a first rectification unit having;

    a first input terminal electrically connected to the first simulation circuit unit; and

    a first output terminal electrically connected to the first terminal of the lighting module;

    a second control module connected to the second terminal of the lighting module and having;

    a second simulation circuit unit having;

    a second capacitor;

    a second resistor parallelly connected to the second capacitor; and

    a second switching element electrically connected to the second capacitor and the second resistor; and

    a second rectification unit having;

    a second input terminal electrically connected to the second simulation circuit unit; and

    a second output terminal electrically connected to the second terminal of the lighting module; and

    a harmonic elimination module parallelly connected to the lighting module with two ends of the harmonic elimination module respectively and electrically connected to the first control module and the second control module, and having;

    a third capacitor;

    a third resistor parallelly connected to the third capacitor; and

    a third switching element connected in series to the parallel-connected third capacitor and the third resistor.
