A triode Q1 is electrically connected to the red lamp bead group 201, a triode Q2 is electrically connected to the yellow lamp bead group 202, and a triode Q3 is electrically connected to the green lamp bead group 203. A boost board is arranged on the relay control board circuit 1. The LED running light circuit 2 is electrically connected to the pin 4 of the boost board. Press the power button led out on the boost board, and the boost board outputs a 5V power supply, and the circuit starts to work. First, 15 LED running light circuits are started, and the red, yellow, and green lights flash alternately. A diode VD is arranged in parallel on the boost board. An I / O port is electrically connected to the interface of the relay control board circuit 1. The I / O port is electrically connected to the pin 2 of the boost board through a resistor R8 and a triode Q4. When the TPP233 touch fast red indicator light is on, the I / O outputs 3V voltage and locks it to provide to the relay board In input, and the relay works. The pins 3 and 4 are disconnected, and the running lights of the red lamp bead group 201, the yellow lamp bead group 202, and the green lamp bead group 203 go out. At the same time, the pins 3 and 5 are conducted, and the +5V power supply is supplied to the full-color LED board, and the full-color LED lights automatically display various color patterns according to the pre-programmed program. Touch the red light-emitting diode again, and the red lamp bead group 201, the yellow lamp bead group 202, and the green lamp bead group 203 then flash;
[0028] The LED running light circuit 2 establishes a communication connection with the relay control board circuit 1 through a chip AMS117. Capacitors C4, C5, and C6 are arranged in parallel between the LED running light circuit 2 and the chip AMS117. The filter capacitors C4, C5, and C6 are used to filter the rectified voltage to eliminate ripples and improve the stability of the power supply;
[0029] The full-color LED lamp beads are a new type of color lamp beads. The LED lamp bead chips of four basic colors, white, red, green, and blue, are used. Each chip is a single-color light-emitting diode. These lamp bead chips are packaged in various forms, the circuit becomes simple, the volume is small, and the installation is more convenient. Each group of colors can be used separately, and can be connected to the driving circuit and the single-chip microcomputer respectively. The structure is simple and the installation is fast and convenient.
[0030] Further, as Figure 1As shown, the models of transistor Q1, transistor Q2, and transistor Q3 are all S9013.

The output end of transistor Q4 is electrically connected to transistor Q5 through resistor R8, and a capacitor C7 is arranged in parallel on resistor R8. According to needs, control circuits such as a dimming circuit and a flashing circuit can be added to achieve functions such as brightness adjustment and flashing of the LED lamp beads. Transistor Q4 has a current amplification effect and can amplify a weak signal into an electrical signal with a larger amplitude value. This is one of the most basic functions of a transistor and has an important impact on the performance and efficiency of electronic circuits. For voltage amplification, current amplification, and power amplification, a transistor can not only amplify voltage signals but also amplify current signals and power signals to meet the requirements of different circuits.
[0032] In addition, as Figure 2 shown, the relay control board circuit 1 is electrically connected to an external power supply through a rectifier bridge and a transformer. An MB10F rectifier bridge is required to convert alternating current into direct current DC. For direct current input, it can directly enter the next part, and a transformer is used for step-down and current limiting to meet the working voltage and current requirements of the LED lamp beads.

A boost board is provided on the relay control board circuit 1. The LED running light circuit 2 is electrically connected to the pin 4 of the boost board. Press the power button led out from the boost board, and the boost board outputs a 5V power supply, and the circuit starts to work. First, 15 LED running light circuits are started, and the red, yellow, and green lights flash alternately. A diode VD is connected in parallel on the boost board. An I / O port is electrically connected to the interface of the relay control board circuit 1. The I / O port is electrically connected to the pin 2 of the boost board through a resistor R8 and a triode Q4. When the TPP233 touch fast red indicator light is on, the I / O outputs 3V voltage and locks it to provide to the relay board In input, and the relay works. The pins 3 and 4 are disconnected, and the running lights of the red LED bead group 201, the yellow LED bead group 202, and the green LED bead group 203 go out. At the same time, the pins 3 and 5 are conducted, and the +5V power supply is supplied to the full-color LED board, and the full-color LED lights automatically display various color patterns according to the pre-programmed program. Touch the red light-emitting diode gently again, and the red LED bead group 201, the yellow LED bead group 202, and the green LED bead group 203 then flash, and the full-color LED lights automatically display various color patterns according to the pre-programmed program.
