In one embodiment, as shown in fig. 1, there is provided a control circuit of an indicator lamp, applied to an activation key including a backlight 50 and an activation indicator lamp 60, the control circuit comprising: a first control loop 10, a second control loop 20, a unidirectional conduction circuit 30, a controller 40, wherein:
the first end of the first control loop 10 is connected to a first end of the backlight 50, and the second end of the first control loop 10 is connected to a second end of the backlight 50.
Since the backlight 50 is disposed in the first control circuit 10, when a potential difference exists between the first end and the second end of the first control circuit 10, a current flows through the backlight 50, and the backlight 50 is turned on.
Specifically, in the case where there is a potential difference between the first end and the second end of the first control loop 10, the potential of the first end of the first control loop 10 is higher than the potential of the second end of the first control loop 10, and current flows from the first end to the second end of the first control loop 10.
The first end of the second control loop 20 is connected to the first end of the start indicator light 60, and the second end of the second control loop 20 is connected to the second end of the start indicator light 60.
Since the start indicator lamp 60 is disposed in the second control circuit 20, when a potential difference exists between the first end and the second end of the second control circuit 20, a current flows through the start indicator lamp 60, and the start indicator lamp 60 is turned on.
Specifically, in the case where there is a potential difference between the first end and the second end of the second control loop 20, the potential of the first end of the second control loop 20 is higher than the potential of the second end of the second control loop 20, and current flows from the first end to the second end of the second control loop 20.
The first end of the unidirectional conduction circuit 30 is connected between the first end of the first control circuit and the first end of the backlight 50, and the second end of the unidirectional conduction circuit 30 is connected between the second end of the second control circuit and the second end of the start-up indicator lamp 60.
Wherein the unidirectional conduction circuit 30 is unidirectional in a direction from a first end to a second end of the unidirectional conduction circuit 30. Subsequent adjustment of the potentials at the first and second ends of the first control loop 10 and the first and second ends of the second control loop 20 is facilitated such that current flows through the unidirectional current conducting circuit 30 rather than through the backlight 50, such that extinction of the backlight 50 may be achieved.

Specifically, the receipt of the start command indicates that the start indicator lamp 60 needs to be turned on, so that the potentials of the first end and the second end of the first control loop 10 and the first end and the second end of the second control loop 20 are controlled respectively, so that the current on the first control loop flows through the unidirectional current conducting circuit 30 from the first end without flowing to the backlight 50, the backlight 50 is turned off, and the potentials of the first end and the second end of the second control loop 20 are controlled to turn on the start indicator lamp 60.
Specifically, the loop through which the current flows at this time is the first end of the first control loop 10→the unidirectional conduction circuit 30→the second end of the second control loop, so the current at the first end of the first control loop 10 does not flow through the backlight 50, the backlight 50 is not turned on, and the current flowing from the unidirectional conduction circuit 30 is transmitted to the downstream node of the start indicator 60, so that the two ends of the unidirectional conduction circuit 30 have a potential difference, and the two ends are not shorted, thereby facilitating smooth current transmission.
In particular, the colors and the brightness of the backlight 50 and the start indicator lamp 60 may be designed to be different, so that the driver can distinguish more clearly.
In this embodiment, by designing a control circuit for the indicator lamp, which is applied to the backlight 50 and the start button for starting the indicator lamp 60, by providing the first control circuit 10, the first end of the first control circuit 10 is connected to the first end of the backlight 50, and the second end of the first control circuit 10 is connected to the second end of the backlight 50, so that when there is a potential difference between the first end and the second end of the first control circuit 10, a current flows through the backlight 50, and the backlight 50 is turned on. By providing the second control loop 20, the first end of the second control loop 20 is connected to the first end of the start indicator lamp 60, and the second end of the second control loop 20 is connected to the second end of the start indicator lamp 60, so that when a potential difference exists between the first end and the second end of the second control loop 20, a current flows through the start indicator lamp 60, and the start indicator lamp 60 is turned on. By providing the unidirectional current conducting circuit 30, the first end of the unidirectional current conducting circuit 30 is connected between the first end of the first control circuit and the first end of the backlight 50, the second end of the unidirectional current conducting circuit 30 is connected between the second end of the second control circuit and the second end of the start-up indicator lamp 60, the unidirectional current conducting circuit 30 is unidirectional in the direction from the first end of the unidirectional current conducting circuit 30 to the second end of the second control circuit and the second end of the start-up indicator lamp 60, so that current on the first control circuit can flow between the second end of the second control circuit and the second end of the backlight 50 from the first end to the second end of the first control circuit, and the first end and the second end of the second control circuit 20 can not flow through the backlight 50 by adjusting the potentials of the first end and the second end of the first control circuit 10 and the first end and the second end of the second control circuit 20, and the potentials of the first end and the second end of the second control circuit 20 can be controlled respectively when the start-up instruction is received, so that the current on the first control circuit can flow from the first end to the first end of the first control circuit and the second end of the second control circuit can not flow through the first end of the first control circuit and the second end of the backlight 50 to start-up indicator lamp 60, and the first end of the backlight 50 can not be controlled to turn off. Therefore, when the starting indicator lamp 60 of the starting key is on, the backlight lamp 50 is turned off, so that the starting indicator lamp 60 is more obvious, a driver can see the brightness change of the starting indicator lamp 60 more clearly, the driver can see the starting indicator information more clearly, and the safety is improved.
In one embodiment, as shown in fig. 2, the unidirectional conduction circuit 30 includes a diode 31, wherein an anode of the diode 31 is connected between a first end of the first control circuit and a first end of the backlight 50, and a cathode of the diode 31 is connected between a second end of the second control circuit and a second end of the start indicator lamp 60.
Specifically, the diode 31 is a unidirectional current that can only flow from the anode of the diode 31 to the cathode of the diode 31.
The controller 40 includes a first interface 1, a second interface 2, a third interface 3, and a fourth interface 4, where the first interface 1 is connected to a first end of the first control loop 10, the second interface 2 is connected to a second end of the first control loop 10, the third interface 3 is connected to a first end of the second control loop 20, the fourth interface 4 is connected to a second end of the second control loop 20, and the controller 40 is configured to control the first interface 1 to be high, the second interface 2 to be first low, the third interface 3 to be high, and the fourth interface 4 to be second low when receiving a start command, so that the first end of the first control loop 10 is high, the second end of the first control loop 10 is first low, the first end of the second control loop 20 is high, and the second end of the second control loop 20 is second low, so that the backlight 50 is turned off and the start indicator 60 is turned on.
Wherein the second low potential is lower than the first low potential. Since the second low potential is lower than the first low potential, the second end of the second control loop 20 has a lower potential than the second end of the first control loop 10, and the first end of the first control loop 10 has a high potential, so that current flows from the first end of the first control loop 10 to the second end of the second control loop 20 having a lower potential through the unidirectional conducting circuit 30, and the current flows from the first end of the first control loop 10 to the unidirectional conducting circuit 30 to the second end of the second control loop. The current at the first end of the first control loop 10 does not flow through the backlight 50 and the backlight 50 does not light up, but the current at the first end of the second control loop 20 flows through the start indicator lamp 60 and the start indicator lamp 60 lights up.
In this embodiment, the unidirectional conduction circuit 30 is realized by designing one diode 31, and then designing the second low potential to be lower than the first low potential, so that the flow direction of the current is controlled, the current flows through the start indicator lamp 60 without leaving the backlight 50, so that the backlight 50 is extinguished while the start indicator lamp 60 is on, the start indicator lamp 60 is more conspicuous, and the driver can more clearly see the brightness change of the start indicator lamp 60.
In one embodiment, as shown in fig. 3, the first interface 1 and the third interface 3 are the same interface of the controller 40.
Specifically, the first interface 1 and the third interface 3 both output high-level signals, so that the same interface can be used, and the manufacturing cost of the controller 40 is saved.
