Capacitor step-down LED drive circuit diagram using thyristor
Source: InternetPublisher:太白金星 Keywords: LED circuit thyristor led drive circuit diagram Updated: 2020/06/13
The figure shows a capacitor step-down drive circuit using a thyristor. In this circuit, the thyristor SCR and R3 form a protection circuit. When the current flowing through the LED is greater than the set value, the SCR conducts at a certain angle, thus shunting the current in the circuit and making the LED work in a constant current state. , thereby preventing the LED from being damaged due to instantaneous high voltage.
