                                 Homemade Electronic Candle Course Presentation

Electronic Candle light, also known as electronic LED candle light or multi-colored candle light, has evolved from simple LED light bulbs shaped like candles to the 4th and 5th generation wind-activated candle lights with increasingly advanced features, such as projection capabilities, sound and wind sensors. The colors available are also increasing, with a trend towards personalized and gift-oriented products.

Experimental Purpose:

The principle of electronic candle light: Amplifies the trigger signal through an amplification circuit, and cuts off the current through the characteristics of a controllable silicon, thereby terminating the circuit.
Experimental Cognition: Thyristor:
As the name suggests, 'unidirectional' means that it only allows direct current to flow in one direction, and 'controllable' means that it can be controlled.
The control of the current is on or off; as for 'silicon', it refers to the material used in the component chip.
The function of the triode:
A pole: the positive pole of the direct current power supply
K pole: DC power supply current output
G pole: Control pole, applying a certain positive voltage can make the thyristor conduct; however, the G pole cannot
Experiment Report:

To cut off a one-way controllable silicon that has already been conducted, because a conducted controllable silicon will form a maintaining current inside, which will make it continue to conduct; only by turning this maintaining current into "zero", can it be stopped from conducting.
In the circuit for the "electronic candle" that we are making:
Point movement switch S1: Used to apply a positive voltage to the G pole; press it once, and the controllable silicon will conduct, and the candle lamp will light up;
Trigger switch S2: Used to short-circuit the A pole and K pole for a moment, at that instant, the current through the thyristor becomes zero (the original current through the thyristor has "detoured" to the copper sheet), the internal maintaining current is lost, and the thyristor breaks, and the candle lamp will also be extinguished.
