[0021] It should be noted that the size of the power supply voltage should be selected according to the working voltage of the first atmosphere lamp head 1 and the lamp head module 2. In the embodiment, the power supply voltage is 12V direct current.
[0022] In the actual application scene, the LIN_IN pin of the first atmosphere lamp head 1 is connected with the automobile IVI central control system, which is used for receiving the LIN signal sent by the automobile IVI central control system. The power supply voltage is input into the VCC pin of the first atmosphere lamp head 1 to supply power for the first atmosphere lamp head 1. After the first atmosphere lamp head 1 receives the LIN signal, the first atmosphere lamp head 1 sends the LIN signal to the lamp head module 2 through the LIN_OUT pin, so that the lamp head module 2 is lit or extinguished according to the received LIN signal. In this way, the control of the lamp head module 2 is realized. It should be noted that when the first atmosphere lamp head 1 receives the LIN signal, the first atmosphere lamp head 1 is lit or extinguished according to the LIN signal at the same time.

In this example, the control chip U1 is an existing automobile atmosphere lamp control chip of the iND83211 type.
[0024] In this example, the first pin of the connecting terminal J1 corresponds to the GND pin of the first atmosphere lamp holder 1, the second pin of the connecting terminal J1 corresponds to the LIN_IN pin of the first atmosphere lamp holder 1, the third pin of the connecting terminal J1 corresponds to the LIN_OUT pin of the first atmosphere lamp holder 1, and the fourth pin of the connecting terminal J1 corresponds to the VCC pin of the first atmosphere lamp holder 1.

[0025] In actual operation, the automobile IVI central control system sends a LIN signal to the LIN_IN port of the control chip U1 through the second pin of the connecting terminal J1. After receiving the LIN signal, the control chip U1 sends the LIN signal to the LIN_OUT port of the control chip U1, and then sends the LIN signal to the third pin of the connecting terminal J1, and then sends the LIN signal to the lamp holder module 2 through the third pin of the connecting terminal J1. The lamp holder module 2 receives the LIN signal and changes the light emitting state according to the LIN signal. At the same time, after receiving the LIN signal, the control chip U1 generates a control signal to the first pin to the third pin of the lamp bead LED according to the LIN signal, so that the lamp bead LED changes its light emitting state.

One end of the capacitor C6 is connected to the ferrite bead L2 and the VBAT port of the control chip U1, and the other end is connected to the capacitor C5 and the ground terminal.
[0027] The first voltage stabilizing component 11 is used to filter and stabilize the voltage input to the control chip. The power supply voltage is input to the first voltage stabilizing component 11 through the fourth pin of the connecting terminal J1, and then output to the control chip U1 after being stabilized by the first voltage stabilizing component 11, thereby supplying power to the control chip U1. Specifically, the diode D2 is used for rectification and to prevent reverse current flow in the circuit. The transient voltage suppression diode E1 is used to suppress the transient voltage of the power supply voltage, thereby protecting the circuit from high voltage transients. The ferrite bead L2 is used to suppress high-frequency noise and spike interference of the input power supply voltage, thereby protecting the circuit to operate stably. The capacitor C7, the capacitor C5 and the capacitor 6 are all used for filtering.
[0028] Further, the first atmosphere lamp head 1 further comprises a second voltage stabilizing component 12, which comprises a capacitor C4, a diode D1, an inductor L1, a capacitor C3, a capacitor C1 and a capacitor C12. One end of the inductor L1 is connected to the BULX1 port of the control chip U1, and the other end is connected to the fourth to sixth pins of the lamp bead LED.

The capacitor C1 is connected in parallel with the capacitor C3. The capacitor C12 is connected in parallel with the capacitor C1.
[0029] The second voltage stabilizing component 12 is used to stabilize and filter the electrical signal input to the lamp bead LED. The electrical signal output by the control chip U1 is input to the second voltage stabilizing component 12. The capacitor C4 is used to filter out high-frequency noise signals output by the control chip U1, and the diode D1 is used for voltage stabilization. The inductor L1, the capacitor C3, the capacitor C2 and the capacitor C2 form a filter circuit to suppress the passage of high-frequency current, so that the electrical signal input to the lamp bead LED is smoother and more stable.
[0030] Further, the lamp holder module 2 comprises a plurality of second ambient light holders 21. Each second ambient light holder 21 has a VCC pin, a LIN_IN pin, a LIN_OUT pin and a GND pin.

The power supply voltage is input to the VCC pin of the second ambient light holder 21 to supply power for the second ambient light holder 21. When the first ambient light holder 1 receives a LIN signal sent by an external automobile central control system, the first ambient light holder 1 outputs the LIN signal from the LIN_OUT pin, the LIN_IN pin of the second ambient light holder 21 connected with the first ambient light holder 1 receives the LIN signal, and then outputs the LIN signal to another second ambient light holder 21, and the plurality of second ambient light holders 21 sequentially transmit the LIN signal, so that the plurality of second ambient light holders 21 are lit or extinguished according to the LIN signal. In this way, the first ambient light holder 1 and the plurality of second ambient light holders 21 are connected in communication through self-addressing.
[0032] It should be noted that the number of the second ambient light holders 21 can be set according to actual use requirements, and therefore, the number of the second ambient light holders 21 is not limited herein.
[0033] In the embodiment, the second ambient light holder 21 is of the same model as the first ambient light holder 1, so that the luminous brightness of the first ambient light holder 1 and the second ambient light holder 21 remains consistent, and any second ambient light holder 21 can be selected as the first ambient light holder 1 to be connected with the external automobile IVI central control system to receive the LIN signal sent by the automobile IVI central control system and control the remaining ambient light holders to be lit or extinguished. It should be noted that the structure of the second ambient light holder 21 is the same as the circuit structure of the first ambient light holder 1, and therefore, the circuit structure of the second ambient light holder 21 is not described herein.
[0034] Further, the plurality of second ambient light holders 21 are connected in parallel with each other, so that the plurality of second ambient light holders 21 do not affect each other.
[0035] The utility model also provides a kind of automobile ambient light, it includes above-mentioned automobile ambient light module.
[0036] In summary, by adopting the first atmosphere lamp holder 1 to receive the LIN signal sent by the automobile IVI central control system, and sending the LIN signal to the lamp holder module 2, the control of the lamp holder module 2 is realized. By adopting the first atmosphere lamp holder 1 to replace the ECU processor, the volume of the automobile atmosphere lamp module is effectively reduced, and the manufacturing cost of the automobile atmosphere lamp module is effectively reduced.
