[0027] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0028] like Figures 1 to 2 As shown, a vehicle-mounted remote-controlled multi-color light circuit 10 according to an embodiment of the present disclosure includes a main atmosphere light module 100 , an RGB atmosphere light module 200 , and a key module 300 . The key module 300 is used to control the on / off states of the main atmosphere light module 100 and the RGB atmosphere light module 200 .

[0029] The main atmosphere light module 100 includes a main light LED control chip MCU2 and a main light LED circuit. The main light LED circuit includes multiple main light LED lamp beads and a first current limiting resistor R1. The positive poles of the multiple main light LED lamp beads are all connected to the first end of the first current limiting resistor R1, and the negative poles of the multiple main light LED lamp beads are all connected to the signal control end LED-2835 of the main light LED control chip MCU2. The second end of the first current limiting resistor R1 is used to connect to the power supply end of the power supply module.

[0030] The RGB atmosphere light module 200 includes an RGB control chip MCU1 and an RGB circuit. The RGB circuit includes multiple red LED lamp beads, multiple green LED lamp beads and multiple blue LED lamp beads. The positive poles of the multiple red LED lamp beads are all used to connect to the power supply end of the power supply module, and the negative poles of the multiple red LED lamp beads are all connected to the red light control end RLED- of the RGB control chip MCU1. The positive poles of the multiple green LED lamp beads are all used to connect to the power supply end of the power supply module, and the negative poles of the multiple green LED lamp beads are all connected to the green light control end GLED- of the RGB control chip MCU1. The positive poles of the multiple blue LED lamp beads are all used to connect to the power supply end of the power supply module, and the negative poles of the multiple blue LED lamp beads are all connected to the blue light control end BLED- of the RGB control chip MCU1. The key module 300 is respectively connected to the switch control end PB2 of the RGB control chip MCU1 and the key signal end PB3 of the main light LED control chip MCU2.

[0031] The PWM signal control terminal IC_2 of the main light LED control chip MCU2 and the PWM signal control terminal IC_1 of the RGB control chip MCU1 are used to connect to the PWM signal output terminal of the microcontroller, so that the microcontroller can control the brightness of the LED lamp beads through its PWM signal output terminal.

[0032] In this embodiment, when the key module 300 is pressed for the first time, the key module 300 generates a high-level signal to the switch control terminal PB2 of the RGB control chip MCU1. Since the signal switching control terminal of the RGB control chip MCU1 is connected to the key signal terminal PB3 of the main light LED control chip MCU2, the high-level signal is simultaneously transmitted to the key signal terminal PB3 of the main light LED control chip MCU2, so that the signal control terminal LED-2835 of the main light LED control chip MCU2 outputs a low-level signal. Since the positive poles of the multiple main light LED lamp beads are connected to the external power supply end through the first current limiting resistor R1, and the negative poles of the multiple main light LED lamp beads are connected to the signal control terminal LED-2835 of the main light LED control chip MCU2, the current output from the external power supply end passes through the LED lamp beads and then flows through the signal control terminal LED-2835 of the main light LED control chip MCU2, and forms a current loop with the ground end, thereby causing the LED lamp beads in the main light LED circuit to be lit.

[0033] Specifically, when the key module 300 is pressed for the second time, the red light control terminal RLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the red LED lamp bead and forms a circuit with the ground terminal through the red light control terminal RLED-, thereby lighting up the red LED lamp bead in the RGB circuit; when the key module 300 is pressed for the third time, the green light control terminal GLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the green LED lamp bead and forms a circuit with the ground terminal through the green light control terminal GLED-, thereby lighting up the green LED lamp bead in the RGB circuit; when the key module 300 is pressed for the fourth time, the blue light control terminal BLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the blue LED lamp bead and forms a circuit with the ground terminal through the blue light control terminal BLED-, thereby lighting up the blue LED lamp bead in the RGB circuit.

[0034] Furthermore, when the key module 300 is pressed for the fifth time, the red light control terminal RLED- and the green light control terminal of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the red LED lamp beads and the green LED lamp beads and respectively forms a circuit with the ground terminal through the red light control terminal RLED- and the green light control terminal GLED-, thereby lighting up the red LED lamp beads and the green LED lamp beads in the RGB circuit; when the key module 300 is pressed for the sixth time, the red light control terminal RLED- and the blue light control terminal BLED- of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the red LED lamp beads and the blue LED lamp beads and respectively forms a circuit with the ground terminal through the red light control terminal RLED- and the blue light control terminal BLED-, thereby lighting up the red LED lamp beads and the blue LED lamp beads in the RGB circuit; when the key module 300 is pressed for the seventh time, the red light control terminal RLED- and the blue light control terminal BLED- of the RGB control chip MCU1 output low-level signals, thereby lighting up the red LED lamp beads and the blue LED lamp beads in the RGB circuit; After block 300, the blue light control terminal BLED- and the green light control terminal GLED- of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the blue LED lamp beads and the green LED lamp beads and respectively forms a circuit with the blue light control terminal and the green light control terminal and the ground terminal, thereby lighting up the blue LED lamp beads and the green LED lamp beads in the RGB circuit; when the key module 300 is pressed for the eighth time, the red light control terminal RLED-, the green light control terminal and the blue light control terminal of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the red LED lamp beads, the green LED lamp beads and the blue LED lamp beads and respectively forms a circuit with the ground terminal through the red light control terminal RLED-, the green light control terminal GLED- and the blue light control terminal BLED-, thereby lighting up the red LED lamp beads, the green LED lamp beads and the blue LED lamp beads in the RGB circuit. Furthermore, the microcontroller changes the brightness of the RGB three-color lamp beads by changing the current output from the PWM signal output terminal to the PWM signal control terminal of the main light LED control chip MCU2 and the RGB control chip MCU1.

[0035] In the aforementioned in-vehicle remote-controlled multi-color light circuit 10, the multiple main LED beads in the main light LED circuit all utilize 2835 LED beads. Due to their large luminous area, high luminous efficiency, and rapid heat dissipation, 2835 LED beads, when used as main ambient lighting, consume less energy, thereby improving the operating efficiency of the in-vehicle remote-controlled multi-color light circuit 10. Furthermore, the key module 300 can be used to change the on / off state of the RGB beads in the RGB circuit, enabling the RGB circuit to output different mixed color combinations. By adjusting the PWM signal output by the microcontroller, the current output to the LED beads is adjusted, thereby adjusting the brightness of the LED beads. This enables the in-vehicle remote-controlled multi-color light circuit 10 to achieve a colorful and brightness-adjustable ambient lighting effect, enhancing the comfort of the vehicle interior.

[0036] like Figure 1 As shown, in one embodiment, the RGB atmosphere light module 200 further includes a second current limiting resistor R2, the first end of the second current limiting resistor R2 is used to be connected to the external power supply end, and the second end of the second current limiting resistor R2 is connected to the power input end of the RGB control chip MCU1. In this embodiment, when the external power supply end provides electrical energy, the current will flow into the power input end of the RGB control chip MCU1 through the second current limiting resistor R2, thereby protecting the RGB control chip MCU1 from damage due to excessive current. When the external power supply voltage fluctuates, directly supplying power to the RGB control chip MCU1 may cause its operating voltage to be unstable, and the voltage drop generated by the current passing through the second current limiting resistor R2 can act as a buffer to keep the operating voltage of the RGB control chip MCU1 stable, thereby improving the reliability and stability of the RGB control chip MCU1.

[0037] like Figure 1 As shown, in one embodiment, the RGB atmosphere light module 200 further includes a first filter capacitor C1, a first end of the first filter capacitor C1 being connected to the power input terminal of the RGB control chip MCU1, and a second end of the first filter capacitor C1 being grounded. In this embodiment, since the working principle of the first filter capacitor C1 is to utilize the charge and discharge characteristics of the capacitor, when an external power supply is used to power the RGB atmosphere light module 200, the first filter capacitor C1 can effectively filter out high-frequency noise and ripple in the power supply, thereby making the voltage transmitted to the power input terminal of the RGB control chip MCU1 more stable, thereby improving the stability of the RGB atmosphere light module 200.

[0038] like Figure 1 As shown, in one embodiment, the RGB atmosphere lamp module 200 further includes a plurality of voltage-dividing resistors, and the positive pole of each LED lamp bead is connected to the external power supply terminal through a voltage-dividing resistor. In this embodiment, the working principle of the voltage-dividing resistor is based on Ohm's law, that is, the voltage across the resistor is proportional to its resistance. When the output voltage of the external power supply terminal is high, each voltage-dividing resistor can share part of its voltage, so that the voltage loaded to the LED lamp bead remains within a safe range, thereby making the voltage-dividing resistor play a protective role to protect the LED lamp bead from overcurrent damage, thereby ensuring that the LED lamp bead can operate under a stable voltage.

[0039] like Figure 1As shown, in one embodiment, the RGB ambient light module 200 further includes a current-steering diode D1. The positive electrode of the current-steering diode D1 is connected to the key module 300, and the negative electrode of the current-steering diode D1 is connected to the switch control terminal PB2 of the RGB control chip MCU1. In this embodiment, because the current-steering diode D1 has unidirectional conductivity, it only allows current to flow from the positive electrode to the negative electrode, thereby ensuring the unidirectional transmission of the switching signal. In addition, the positive electrode of the current-steering diode D1 is connected to the key module 300, and the negative electrode is connected to the switch control terminal PB2 of the RGB control chip MCU1. This allows the current-steering diode D1 to prevent current backflow or transient voltage from damaging the RGB control chip MCU1, thereby improving the accuracy and stability of the control signal.

[0040] like Figure 1 As shown, in one embodiment, the RGB control chip MCU1 is model NY8BE62D. In this embodiment, when the RGB control chip MCU1 is powered on, the NY8BE62D receives control signals from the microcontroller via its PWM signal output terminal. Based on this, the NY8BE62D outputs corresponding PWM dimming signals to the LEDs, adjusting the current output to the LEDs and thus adjusting their brightness. Furthermore, when a user presses a key, a high-level signal generated by the key module 300 is transmitted to the switch control terminal of the NY8BE62D. Specifically, after the NY8BE62D detects the signal, it uses an internal counter to identify the number of key presses based on a preset logical relationship and controls the lighting status of different LEDs accordingly. Based on the number of key presses and its internal logic, the NY8BE62D outputs low-level signals through its red, green, and blue control terminals, causing the corresponding LEDs to form a current loop with the ground terminal, thereby controlling the lighting of the different colored LEDs in the RGB circuit.

[0041] like Figure 2 As shown, in one embodiment, the main atmosphere light module 100 also includes a third current limiting resistor R3, the first end of the third current limiting resistor R3 is used to connect to the external power supply end, and the second end of the third current limiting resistor R3 is connected to the power input end of the main light LED control chip MCU2. In this embodiment, when the external power supply end provides voltage, the current passes through the third current limiting resistor R3 and then flows into the power input end of the main light LED control chip MCU2, so that the third current limiting resistor R3 can limit the current flowing into the main light LED control chip MCU2 to prevent the control chip from being damaged due to excessive current. At the same time, the third current limiting resistor R3 also acts as a voltage divider to divide the external power supply voltage, thereby ensuring that the main light LED control chip MCU2 is within its rated operating voltage range, thereby improving the stability and reliability of the main atmosphere light module 100.

[0042] like Figure 2 As shown, in one embodiment, the main atmosphere lamp module 100 further includes a second filter capacitor C2, the first end of the second filter capacitor C2 is connected to the power input terminal of the main light LED control chip MCU2, and the second end of the second filter capacitor C2 is grounded. In this embodiment, when the voltage provided by the external power supply terminal fluctuates, the second filter capacitor C2 can store and release electrical energy so that it can effectively filter out high-frequency noise and ripple in the power supply. Specifically, when the voltage increases, the capacitor will absorb excess electrical energy, and when the voltage decreases, the capacitor will release the stored electrical energy, so that the voltage transmitted to the power input terminal of the main light LED control chip MCU2 is more stable, thereby improving the stability of the main atmosphere lamp module 100.

[0043] like Figure 1 As shown, in one embodiment, the second filter capacitor C2 is an adjustable capacitor. In this embodiment, since the capacitance value of the second filter capacitor C2 will affect the cutoff frequency of the filter, when the second filter capacitor C2 allows the user to flexibly adjust the capacitance value according to actual needs, the second filter capacitor C2 can accurately control the cutoff frequency of the filter, so that the main atmosphere light module 100 can adapt to the signal filtering requirements of different frequencies, thereby improving the flexibility and accuracy of the second filter capacitor C2.

[0044] An ambient light includes any of the aforementioned in-vehicle remote-controlled multi-color light circuits 10. In this embodiment, when the key module 300 is pressed for the first time, the key module 300 generates a high-level signal to the switch control terminal PB2 of the RGB control chip MCU1. Because the signal switching control terminal of the RGB control chip MCU1 is connected to the key signal terminal PB3 of the main light LED control chip MCU2, the high-level signal is simultaneously transmitted to the key signal terminal PB3 of the main light LED control chip MCU2, causing the signal control terminal LED-2835 of the main light LED control chip MCU2 to output a low-level signal. Because the positive electrodes of the multiple main light LED beads are all connected to the external power supply terminal via the first current-limiting resistor R1, and the negative electrodes of the multiple main light LED beads are all connected to the signal control terminal LED-2835 of the main light LED control chip MCU2, the current output from the external power supply terminal passes through the LED beads and then flows through the signal control terminal LED-2835 of the main light LED control chip MCU2, forming a current loop with the ground terminal, thereby illuminating the LED beads in the main light LED circuit. Specifically, when the key module 300 is pressed for the second time, the red light control terminal RLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the red LED lamp bead and forms a circuit through the red light control terminal and the ground terminal, thereby lighting up the red LED lamp bead in the RGB circuit; when the key module 300 is pressed for the third time, the green light control terminal GLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the green LED lamp bead and forms a circuit through the green light control terminal and the ground terminal, thereby lighting up the green LED lamp bead in the RGB circuit; when the key module 300 is pressed for the fourth time, the blue light control terminal BLED- of the RGB control chip MCU1 outputs a low-level signal, so that the current output by the external power supply flows through the blue LED lamp bead and forms a circuit through the blue light control terminal and the ground terminal, thereby lighting up the blue LED lamp bead in the RGB circuit.Furthermore, when the key module 300 is pressed for the fifth time, the red light control terminal RLED- and the green light control terminal of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the red LED lamp beads and the green LED lamp beads and respectively forms a circuit with the red light control terminal and the green light control terminal and the ground terminal, thereby lighting up the red LED lamp beads and the green LED lamp beads in the RGB circuit; when the key module 300 is pressed for the sixth time, the red light control terminal RLED- and the blue light control terminal of the RGB control chip MCU1 output low-level signals, so that the current output by the external power supply flows through the red LED lamp beads and the blue LED lamp beads and respectively forms a circuit with the red light control terminal and the blue light control terminal and the ground terminal, thereby lighting up the red LED lamp beads and the blue LED lamp beads in the RGB circuit; when the key module 300 is pressed for the seventh time, After 00, the blue light control terminal BLED- and the green light control terminal of the RGB control chip MCU1 output low-level signals, causing the current output by the external power supply to flow through the blue and green LED beads, respectively, through the blue light control terminal and the green light control terminal to form a circuit with the ground terminal, thereby illuminating the blue and green LED beads in the RGB circuit. When the key module 300 is pressed for the eighth time, the red light control terminal RLED-, the green light control terminal, and the blue light control terminal of the RGB control chip MCU1 output low-level signals, causing the current output by the external power supply to flow through the red, green, and blue LED beads, respectively, through the red light control terminal, the green light control terminal, and the blue light control terminal to form a circuit with the ground terminal, thereby illuminating the red, green, and blue LED beads in the RGB circuit. Furthermore, the microcontroller changes the current output from the PWM signal output terminal to the PWM signal control terminal of the main light LED control chip MCU2 and the RGB control chip MCU1 to change the brightness of the three RGB color beads.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] 1. In the aforementioned in-vehicle remote-controlled multi-color light circuit 10, the multiple main LED beads in the main light LED circuit all utilize 2835 LED beads. Due to their large luminous area, high luminous efficiency, and rapid heat dissipation, 2835 LED beads, when used as main ambient lighting, consume less energy, thereby improving the operating efficiency of the in-vehicle remote-controlled multi-color light circuit 10. Furthermore, the key module 300 can be used to change the on / off state of the RGB beads in the RGB circuit, enabling the RGB circuit to output different mixed color combinations. By adjusting the PWM signal output by the microcontroller, the current output to the LED beads is adjusted, thereby adjusting the brightness of the LED beads. This enables the in-vehicle remote-controlled multi-color light circuit 10 to achieve a colorful and brightness-adjustable ambient lighting effect, enhancing the comfort of the vehicle interior.
