An annular LED light board 3 is disposed within the metal upper shell 1, and the annular LED light board 3 is encapsulated within the metal upper shell 1 via an annular lampshade 4. A positive contact 5 and an insulating bushing 6 are disposed within the metal lower shell 2. The insulating bushing 6 is mounted at the center of the metal lower shell 2 and sleeved on the outer circumference of the positive contact 5. A buzzer 7 is mounted on the metal lower shell 2.

[0023] Example:

[0024] The LED lamp in this utility model uses a high-efficiency red LED. When the above-mentioned sound and light type electric shock device is powered on, after the positive contact 5 is energized, the current passes through the buzzer 7 and the LED light string of the annular LED light board 3, the buzzer 7 emits a buzzing sound, and the LED light string of the annular LED light board 3 begins to emit light.

[0025] In combination with the circuit diagram of the present invention, a capacitor C1 is added to the circuit diagram, wherein C1 is a 1000uF energy storage electrolytic capacitor. Capacitor C is used to be connected to the boost circuit to extend the actual working time. The actual working time of the prototype circuit is extended to about 200mS.

[0026] The diode D2 prevents the capacitor from supplying power to the buzzer, thereby preventing abnormal low voltage sounding.

[0027] The circuit board 8 is provided with a DC-DC boost circuit and an LED boost constant current drive circuit. The LED boost constant current drive circuit is used to be electrically connected to the LED light string on the annular LED light board 3 for stable output of the LED light string, improving luminous efficiency, and having good stability and consistency.

[0028] The insulating bushing may be a nylon insulating bushing.

[0029] The specific testing process of this utility model is as follows:

[0035] As a further explanation of the present invention, the buzzer 7 is fixed to the upper end surface of the metal lower shell 2 by two sets of M3 screws. The buzzer 7 adopts an active buzzer with an internal oscillator. The buzzer operating voltage is 3-28V. The metal upper shell 1 and the metal lower shell 2 are fixed by two sets of M3 screws.

[0036] As a further elaboration of the present invention, the annular lampshade 4 is fixed to the metal upper shell 1 by gluing.

An embedding slot 9 is provided at the end of the metal lower shell 2, and the circuit board 8 and the resistors are fixed in the embedding slot 9 by epoxy resin potting. The four 50Ω power resistors are equivalent to the load of the actual electric shock device and can ensure that the loop detection before the electric shock is normal.
