The invention will be further explained and explained with reference to the drawings and the embodiments in the description.
To at least partially solve one of the above problems, referring to fig. 1, the present invention provides an indicator lamp circuit, which includes a power conversion module 10, a first capacitor C1, an indicator lamp module 20, and a flash module, wherein the indicator lamp module 20 includes an indicator lamp LD1, and the flash module includes a controller and a switching device KV 1;
the first output end a1 of the power conversion module 10 is connected to one end of the first capacitor C1, and the second output end a2 of the power conversion module 10 is connected to the other end of the first capacitor C1;
one end of the first capacitor C1 is connected with one end of the indicator light LD1, the other end of the indicator light LD1 is connected with the first end of the switch device KV1, and the second end of the switch device KV1 is connected with the other end of the first capacitor C1;
and the controller is used for controlling the switching device KV1 to change the flashing frequency and brightness of the indicator lamp LD 1.
Specifically, the power conversion module 10 is used for converting an input three-phase alternating voltage (UaUbUc) into a first direct voltage;
the first capacitor C1 is connected in parallel to the two output ends of the power conversion module 10, and is configured to filter an ac component in the dc voltage output by the power conversion module 10, so that the dc voltage is smoother.
The indicating lamp LD1 is used for indicating the state of the three-phase alternating current power supply, the direct current voltage filtered by the first capacitor C1 is used for supplying power to the indicating lamp LD1, the indicating lamp LD1 shows that the three-phase alternating current power supply is normal when being lighted, and shows that the three-phase alternating current power supply is abnormal when the indicating lamp LD1 is extinguished.
Because the indicator light LD1 is always in the working state of lighting for a long time and is easy to generate heat and damage, the service life of the indicator light LD1 is short, and based on the technical problem, the application controls and adjusts the flashing frequency and the brightness of the indicator light LD1 by controlling the on-off of the switch through the additionally arranged controller and the switch device KV1, the switch device KV1 is connected in series in the circuit where the indicator light LD1 is located, and further the heat emitted by the indicator light LD1 under the condition of long-time working is reduced, and the service life of the indicator light LD1 is prolonged.
Further as an optional implementation manner, the indicator light circuit further includes a voltage dividing module 30, a first end B1 of the voltage dividing module 30 is connected to the first output end a1 of the power conversion module 10, a second end B2 of the voltage dividing module 30 is connected to the second output end a2 of the power conversion module 10, a third end B3 of the voltage dividing module 30 is connected to one end of the first capacitor C1, and a first end B1 or a second end B2 of the voltage dividing module 30 is connected to the other end of the first capacitor C1.
Specifically, referring to fig. 2, the indicator light circuit of the present application further includes a voltage dividing module 30, and the voltage dividing module 30 divides the first dc voltage U output by the power conversion module 10A1A2Step-down is performed, the stepped-down voltage is the second direct current voltage U between the third end B3 and the second end B2 of the voltage dividing module 30B3B2(referring to fig. 1, one end of the first capacitor C1 is connected to the third end B3 of the voltage dividing module 20, and the other end of the first capacitor C1 is connected to the second end B2 of the voltage dividing module 20, although the other end of the first capacitor C1 may also be connected to the first end B1 of the voltage dividing module 20, and finally, the voltage at the two ends of the first capacitor C1 may be reduced by the voltage dividing module), and the second dc voltage U is generatedB3B2Is obviously less than the first direct current voltage U of the output end of the rectifier moduleA1A2Second DC voltage UB3B2Filtering by a first capacitor C1 to obtain a third direct currentAnd the third direct current voltage is used for supplying power to the indicator light LD 1. Due to the second DC voltage U across the first capacitor C1B3B2Is much smaller than the first DC voltage UA1A2Therefore, the first capacitor C1 does not need to have a large capacitance value, and therefore, the volume of the first capacitor C1 is also small, so that the volume of the indicator light circuit is reduced, and the price of the capacitor is reduced under the condition that the volume of the capacitor is small, so that the circuit cost is also saved.
It should be noted that, in this embodiment, the voltage dividing module 30 is implemented by dividing voltage through the first resistor R1 and the second resistor R2, and of course, the voltage dividing module 30 may also implement voltage division through a combination of other resistors, which is not described herein too much.

Referring to fig. 2, specifically, the current output at two ends of the power conversion module 10 is large, so that the overcurrent protection device 40 needs to be adopted to prevent other components in the circuit from being burned out when the current is too large, and the overcurrent protection device 40 may adopt an electronic fuse, an air switch, a circuit breaker, and the like.
As a further alternative, the power conversion module 10 is a three-phase full-bridge rectification circuit.
Specifically, the more common three-phase rectifier circuit is three-phase full-bridge rectifier circuit (by 6 diode components) and three-phase half-bridge rectifier circuit (by 3 diode components), but three-phase half-bridge rectifier circuit's output only has 3 pulse waves (three-phase full-bridge rectifier output 6 pulse waves), and three-phase half-bridge rectifier circuit still has serious direct current magnetizing current problem moreover, consequently, adopts three-phase full-bridge rectifier circuit as a mode of realization of power conversion module 10 in this embodiment.
Further as an alternative embodiment, the indicator light module 20 further includes a current limiting resistor R3, and the current limiting resistor R3 is connected in series with the indicator light LD 1.
Specifically, the indicator light module 20 of the present application further includes a current limiting resistor R3, and the current limiting resistor R3 is connected in series with the indicator light LD1, so as to increase the resistance of the indicator light LD1 and prevent the indicator light LD1 from being burned out by a large current.
Further as an alternative embodiment, the switching device KV1 is a photo coupler.
Specifically, the controller controls the brightness and the flashing frequency of the indicator light LD1 by controlling the on-off of the switching device KV1, and while the photoelectric coupler is adopted as the switching device KV1 in the present embodiment, the photoelectric coupler can be used to isolate the controller from the circuit modules such as the indicator light module 20, the first capacitor C1, and the voltage dividing module 30, so as to avoid the controller from being interfered by the front-end circuit.

In addition, the control switch device KV1 is turned off in the time interval T1 between pulse waves, the indicator light LD1 is in an off state in the time interval T1, the indicator light LD1 is turned on again until the next pulse wave comes, and the purpose of adjusting the flashing frequency of the indicator light LD1 is finally achieved by controlling the indicator light LD1 to be turned on and off alternately, so that the indicator light LD1 is not required to be in an on working state all the time.
