Illuminated Christmas tree decorative light control circuit

An illuminated Christmas tree decorative light control circuit, comprising:

• a main controller and at least one branch controller electrically connected to the main controller;
• wherein
• the main controller comprises a main control circuit and a control output circuit, the main control circuit having a main control chip arranged therein, the main control chip being an erasable programmable read only memory (EPROM) with a plurality of pins and being equipped with a built-in dimming function in order to control and generate a control signal for a plurality of lighting modes, the control output circuit being configured to receive the control signal outputted by the main control circuit and convert the control signal to output a main control signal;
• and
• each one of the at least one branch controller comprises a signal transmission circuit, a driving circuit and a connecting terminal, the signal transmission circuit being configured to receive the main control signal outputted by the control output circuit, and being connected to the connecting terminal via the driving circuit and being divided into a plurality of terminal sets, thereby using each terminal set for connecting to a decorative light module installed on each branch of a Christmas tree, such that each decorative light module is able to receive an operation control of the main controller via each one of the at least one branch controller.
