[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The utility model provides a circuit for a water-flow turn signal lamp of a vehicle lamp, such as Figure 1 As shown, it includes a light control module, which is used to receive the light control information output by the vehicle control module and control the actions of all lights on the vehicle according to the light control information. The output end of the light control module is electrically connected to the steering module, which is used to control the action of the turn signal module.

[0027] In order to make the turn signal present a flowing water effect, the steering module is electrically connected to the turn signal module through the power supply module. The turn signal module includes several light groups. The power supply module supplies power to the several light groups respectively. The several light groups light up and go out in a specific sequence, so that the turn signal module presents a flowing water animation effect, thereby improving the viewing appeal of the turn signal.

[0028] like Figure 2 As shown, the steering module includes a control chip U1, which communicates with the vehicle light control module through the DAT port and the CLK port to receive the driver. The control chip U1 includes an X1 port and an X2 port, which communicate with the vehicle light control module. The X1 port is used to receive the fault information of the turn signal, and the control chip U1 can give feedback based on the fault information and turn off the turn signal module. The X2 port is used to receive the control information of the turn signal, and the control chip U1 controls the action of the turn signal module based on the control information.

[0029] In order to control the operation of each light group individually, the control chip U1 leads to several PWM ports, which are used to transmit pulse signals with different phases and pulse widths. Figure 3As shown, the power supply module includes a power supply chip U2, which includes a number of one-to-one corresponding input ports and a number of output ports. The input ports of the power supply chip U2 are electrically connected to a number of PWM ports, and the corresponding output ports are electrically connected to a number of lamp groups. The control chip U1 controls the pulse signal output by each PWM port to control the action of the corresponding lamp group.

[0030] An embodiment of the present application is as follows: the power supply module includes a power supply chip U2 and a power supply chip U3, and the VIN ports of the power supply chip U2 and the power supply chip U3 are electrically connected to the power supply V to provide power to the turn signal module. The circuit structures of the power supply chip U2 and the power supply chip U3 are exactly the same, the power supply chip U2 includes three input ports and three output ports, and the PWM ports include PWM4 port, PWM5 port and PWM6 port.

[0031] PWM4, PWM5 and PWM6 are electrically connected to the three input ports respectively, and the three output ports are IOUT4, IOUT5 and IOUT6 respectively. IOUT4, IOUT5 and IOUT6 are electrically connected to the three lamp groups respectively to supply power to the lamp groups.

[0032] When power is supplied, PWM4, PWM5 and PWM6 ports transmit pulse signals with different phases respectively, and IOUT4, IOUT5 and IOUT6 ports output currents of the same magnitude at different times, so that the three light groups light up in sequence, thereby producing the effect of flowing lights.

[0033] like Figure 4 As shown, the lamp group includes a plurality of diodes L connected in series in sequence, and each diode L is connected to a capacitor C, so that the lamp group can produce a slow lighting and slow extinguishing effect, and the plurality of diodes L in a single lamp group are distributed in a wave shape.

[0034] An embodiment of the present application is: the diode L includes a diode L16, a diode L17 and a diode L18 connected in series in sequence, the positive electrode of the diode L16 is electrically connected to the IOUT1 port, and the negative electrode of the diode L18 is grounded. After the IOUT1 port is powered on, the capacitors C corresponding to the diodes L16, L17 and L18 are charged, the current flowing through the diodes L16, L17 and L18 slowly increases, and the diodes L16, L17 and L18 slowly light up; after the IOUT1 port is powered off, the three capacitors C are discharged at the same time, and the corresponding diodes L16, L17 and L18 slowly go out.

[0035] To facilitate monitoring of fault conditions of the lamp group, the power supply chip U2 includes VSNS ports with the same number as the output ports. A resistor R42 is connected in series between the VSNS port and the corresponding IOUT, and a resistor R48 is connected in series between the VSNS port and the ground. When the lamp group is open-circuited and short-circuited, the pressure of the VSNS port changes to obtain a fault signal of the lamp group.

[0036] The power supply chip U2 is electrically connected to the control chip U1 through the FAULT port to transmit the fault signal to the control chip U1 (the F port of the control chip U1 will receive the fault signal).

[0037] The control chip U1 includes an X3 port, which is connected to the headlight control module through a transmission circuit. The transmission circuit includes a transistor Q1, a base of the transistor Q1 is electrically connected to the X3 port, an emitter of the transistor Q1 is grounded, a resistor R29 is connected in series between the collector of the transistor Q1 and the pull-up power supply, and a resistor R31 is connected in series between the collector of the transistor Q1 and the headlight control module.

[0038] The working process is: when the lamp group has no fault, the transistor Q1 is in the disconnected state, the resistor R31 divides the voltage, and the collector voltage of the transistor Q1 is not zero; when the lamp group fails, the voltage of the X3 port changes, making the transistor Q1 turned on, and the collector voltage of the transistor Q1 is zero.

[0039] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model.
