When the main control chip U1 outputs a high level at its L2 pin, it sends a trigger voltage to transistor Q1 through resistor R4, causing transistor Q3 to conduct. LED1 then has a positive voltage, and transistor Q1 simultaneously causes transistor Q5 to conduct, resulting in a negative voltage at LED2. With both positive and negative voltages, the LED string can be lit. In this way, the main control chip can alternately output voltage through its L1 and L2 pins, enabling the LED string to achieve dual-color changes. By outputting intermittent and gradual voltages, the LED string will flash and change color, achieving various variations. The principle of group control lies in the fact that the controller has a transceiver chip U2, which can both transmit and receive, enabling mutual control.

[0026] Example 2

[0027] In Embodiment 2 of this application, as Figure 2 The illustrated tree light device includes multiple tree light bodies 200, each connected to the aforementioned inter-controller 100. Specifically, the main control chip U1 presets the LED string lighting change function of the tree light body 200 and its LED string lighting effect; each tree light body 200's string includes at least one LED, preferably multiple LEDs, and the LEDs of each tree light body are connected to the inter-controller (as in Embodiment 1); the transceiver chip U2 can receive external signals of the same code rate and can also transmit signals, which can be received by an external receiver of the same code rate, causing the light string to change accordingly; for example... Figure 2 Each tree light in the system is equipped with an interconnect controller as described in Example 1. Each tree is connected to the interconnect controller, and when powered on, pressing the controller switch K1 transmits a signal of the same code rate. The transceiver chip U2 receives the signal, and the light string reacts accordingly to the tree light corresponding to the interconnect controller that emitted the signal, achieving mutual control. This ingenious design creates a synchronized lighting effect and is easy to use; adjusting a single tree light adjusts all the tree lights, increasing flexibility in use and adjustment. The tree light body 200, through the internal circuit logic of the interconnect controller 100 (such as the interaction between the main control chip U1 and the switch module), achieves precise control of the LED light string, creating diverse lighting effects. Since all tree light bodies are connected to the interconnect controller, and these interconnect controllers can communicate and coordinate with each other, an overall synchronized lighting effect can be achieved, enhancing the aesthetic appeal and artistry of the light display.
