1. An intelligent lamp string with integrated power control, comprising:
a power plug connected to a mains supply,
a power control module,
a plurality of lamp holders; and
a plurality of bulbs,
wherein the power plug is electrically connected to the power control module for controlling power and outputting a driving signal; the power control module is provided with an output positive terminal (V+) and an output negative terminal (V−);
the plurality of lamp holders are electrically connected to the output positive terminal (V+) and the output negative terminal (V−), respectively; address signal modules for distinguishing different lamp holders are arranged in the lamp holders; address identification and processing modules for identifying addresses of the lamp holders and outputting corresponding signals are arranged in the bulbs; the bulbs are detachably connected to the lamp holders to form a communication loop; the address identification and processing modules in the bulbs are electrically connected to the address signal modules in the lamp holders; and, the address identification and processing modules identify the address signal modules and output corresponding electrical signals to control the change of the bulbs;
wherein the power control module comprises an AC-DC step-down circuit, a control circuit and an output driving circuit the AC-DC step-down circuit outputs a power supply (VCC) to the control circuit the control circuit comprises a first resistor ((R15), a first diode (D5), a first capacitor ((C11)), a second capacitor (C12)), a first control chip (U5), a wireless control module (H1), a switch (SW1) and a control key (S1); the first control chip (U5) is specifically FT60F021-RB, an output end of the AC-DC step-down circuit is connected to one end of the first resistor (R15), the other end of the first resistor (R15) is connected to a first pin of the first control chip (U5), a cathode of the first diode (D5) is connected to the first pin of the first control chip (U5), and an anode of the first diode (D5) is grounded; one end of the first capacitor (C11) is connected to the first pin of the first control chip (U5), while the other end of the first capacitor (C11) is grounded; one end of the second capacitor (C12) is connected to the first pin of the first control chip (U5), while the other end of the second capacitor (C12) is grounded; a first pin of the wireless control module (H1) is connected to a fifth pin of the first control chip (U5); a fourth pin of the wireless control module (H1) is connected to a fourth pin of the first control chip (U5); the switch (SW1) is connected to an eighth pin of the first control chip (U5); the control key (S1) is connected to a sixth pin of the first control chip (U5); and, the switch (SW1) controls the connection or disconnection between the eighth pin of the first control chip (U5) and the sixth pin of the first control chip (U5) through the control key (S1).
