All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The embodiment of the utility model discloses an intelligent multipurpose flash control circuit, as shown in fig. 1, comprising: the device comprises a controller, a control circuit, a reversing circuit and a flash bubble; the flash bulbs are arranged in series to form a light string, and each flash bulb is formed by connecting two nonpolar LED lamps with different colors end to end; the controller is electrically connected with the control circuit and outputs a control signal to the control circuit; the control circuit controls the reversing circuit to act according to the control signal, switches the current transmission path and transmits the control signal to the flash bubble.

Specifically, the stationary contacts are 1 and 2 respectively; the movable contacts are 3, 4 and 5; the fixed contact 1 and the fixed contact 2 are respectively connected with two ends of the light string; the movable contact 3 is connected with the positive electrode of the power supply; the movable contact 4 is connected with the drain electrode of the MOS tube; the movable contact 5 is connected with the positive electrode of the power supply; the relay drives the electric shock to switch, the static contact 1 is connected with the movable contact 3, the static contact 2 is connected with the movable contact 4 due to the unidirectional conductivity of the diode, and the first LED lamp in the flash lamp string is lighted; the fixed contact 1 is connected with the movable contact 4, the fixed contact 2 is connected with the movable contact 5, and a second path of LED lamps in the flash lamp string are lighted.
In order to further optimize the above technical solution, the control circuit includes: the MOS transistor comprises a first triode, a second triode and a MOS transistor; the base electrode of the first triode is connected with the first output end of the controller, the collector electrode of the first triode is connected with a high level, and the emitter electrode of the first triode is connected with the grid electrode of the MOS tube; the drain electrode of the MOS tube is connected with a public movable contact in the movable contacts; the source electrode of the MOS tube is grounded; the base of the second triode is connected with the second output end of the controller, the collector of the second triode is connected with the relay, and the emitter of the second triode is grounded.

In order to further optimize the technical scheme, the two ends of the relay are connected with the flywheel diode in parallel.
When the relay is closed, the circuit enters an operating state, and an induced electromotive force is generated at the moment, and the diode does not play a role. However, at the moment when the relay is disconnected, the principle of electromagnetic induction indicates that the current cannot be suddenly changed, the induced electromotive force can generate reverse voltage to an original in the circuit, and when the reverse voltage is higher than the reverse breakdown voltage of the original, the original such as a triode can be damaged.

In order to further optimize the technical scheme, a plurality of groups of flash bubbles are arranged.
The working principle of the circuit is as follows:
first mode: when the 7 pin of the controller IC2 outputs pulse waves, the first triode Q1 works to drive the MOS tube Q2 to perform the non-disconnection switching action. When the 6 pin output of the controller IC2 is low, the second transistor Q3 is inactive, the relay J is inactive, and the default contact is pulled up. Therefore, the current flows in from the positive electrode of the power supply, is output to the lamp string through the P1, flows back through the P2, and generates square wave pulse current through the switching action of the MOS tube Q2, and flows to the negative electrode of the power supply to form a loop (white normally-on effect, white flash is controlled by square wave pulses).
Second mode: when the pin 7 of the controller IC2 outputs high level, the first triode Q1 works to drive the MOS tube Q2 to be completely opened. When the 6 pin output of the controller IC2 is low, the second transistor Q3 is inactive, the relay J is inactive, and the default contact is pulled up. Therefore, the current flows in from the positive electrode of the power supply, is output to the lamp string through P1, flows back through P2, and flows back to the negative electrode of the power supply through the MOS tube Q2, so that a loop (white normally-on+white flickering effect) is formed.
Third mode: when the 7 pin of the controller IC2 outputs pulse waves, the first triode Q1 works to drive the MOS tube Q2 to perform the non-disconnection switching action. When the 6 pin of the controller IC2 outputs a high level, the second triode Q3 works, the relay J acts, and the double contacts dial downwards. Therefore, the current flows in from the positive electrode of the power supply, is output to the lamp string through the P2, flows back through the P1, and generates square wave pulse current through the switching action of the MOS tube Q2, and flows to the negative electrode of the power supply to form a loop (warm white normal lighting effect, white flash is controlled by square wave pulse).
Fourth mode: when the pin 7 of the controller IC2 outputs high level, the first triode Q1 works to drive the MOS tube Q2 to be completely opened. When the 6 pin of the controller IC2 outputs a high level, the second triode Q3 works, the relay J acts, and the double contacts dial downwards. Therefore, the current flows in from the positive electrode of the power supply, is output to the lamp string through P2, flows back through P1, and flows back to the negative electrode of the power supply through the MOS tube Q2, so that a loop (effects of warm Bai Changliang +warm white flickering and the like) is formed.
Other modes are also included to achieve different dynamic flicker effects depending on the controller.
