1. An assembled structure of a large-sized LED lamp, comprising:

  • a substrate (1);

    a plurality of LED modules (2) fixed on one surface of the substrate (1), each LED modules (2) comprising a circuit board (21) and a plurality of LEDs (22) fixedly connected to the circuit board (21);

    a lamp mask (3) mounted on the surface of the substrate (1) provided with the LED modules (2) so as to cover the LED modules (2);

    a plurality of heat-dissipating modules (5) fixedly provided on the other surface of the substrate (1), each heat-dissipating module (5) provided to correspond to each LED module (2); and

    a lamp cover (6) mounted on the surface of the substrate (1) provided with the heat-dissipating modules (5) so as to cover the heat-dissipating modules (5),wherein each heat-dissipating module (5) comprises a plurality of heat-dissipating fins (51) arranged at identical intervals, two U-shaped heat pipes (52) penetrating through the heat-dissipating fins (51), andwherein a hole is formed on each heat-dissipation fin (51) so as to make a tunnel formed in the heat-dissipating module (5), and both elongated ends of each U-shaped heat pipe (52) are embedded in the heat-dissipating fins (51) to respectively locate above and beneath the tunnel while a lower elongated end of the U-shaped heat pipe (52) has a flat surface exposed out and leveled with a lower surface of the heat-dissipating module (%) so that when the heat-sissipating module (5) is fixed, the flat surface together with the lower surface are directly contacted on the surface of the substrate (1) provided with the heating-dissipating modules.
