1. An AC two-wire LED high voltage lamp string with synchronous dimming and color adjustment, comprising a high voltage controller and a lamp string group, wherein the high voltage controller comprises a control box, and a first power supply module, a switch control circuit, a first microcontrol unit and a mode adjustment switch which are arranged in the control box and connected in sequence; and the first microcontrol unit is connected with the first power supply module;
the first power supply module is provided with a first AC input end for external connection, and the first AC input end comprises a live line end and a neutral line end; the first microcontrol unit is used to receive a switch signal of the mode adjustment switch and transmit the signal to the switch control circuit; the switch control circuit is used for waveform modulation encoding of AC sine waves inputted by the first power supply module under the signal control of the first microcontrol unit;
the first microcontrol unit is used for zero-crossing detection of AC of the first power supply module;
the high voltage controller is also provided with an AC output end; the AC output end comprises a first AC output end connected with the first power supply module and a second AC output end connected with the switch control circuit; the control box is provided with a connecting hole, and the first AC input end and the AC output end are respectively connected with the outside through the connecting hole; the AC output end is connected with a connector, and the connector is detachably connected with the LED lamp string group;
the LED lamp string group comprises LED lamps which are connected mutually; the LED lamp string group is provided with a tail plug joint connected with the connector;
a second power supply module, a carrier signal detecting module, a second microcontrol unit and a lighting module are arranged in the LED lamps;
the second power supply module is provided with a second AC input end electrically connected with the AC output end, and the second power supply module is used for supplying power for the second microcontrol unit and the lighting module;
the second power supply module is connected with the carrier signal detecting module, the second microcontrol unit and the lighting module in sequence; the carrier signal detecting module is used for detecting a carrier signal received by the second AC input end and transmitting a carrier code value to the second microcontrol unit; after receiving the carrier signal, the second microcontrol unit executes a corresponding lighting instruction so that the lighting module enters a lighting mode which is set by the code value.
