Working principle of the LED lamp with the thermal locking device;
when in a working state: the LED lamp body 11 is lighted, and the limiting electromagnet 12 has magnetism, so that the attraction portion 141 is attracted by the limiting electromagnet 12 on the corresponding side, so that the pair of moving connection plates 14 is closest, the heat dissipation through hole 140 communicates with the heat dissipation hole 100, and thus the heat generated by the LED lamp body 11 is discharged through the heat dissipation through hole 140 and the heat dissipation hole 100;
