220vled water lamp string how to connect, that is, 220 of the electricity
The time of the water lamp is controlled by adjusting the capacity value of the capacitor.
The triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.
On the way of C1, R1, L1, R2 varistor, the primary power supply filter circuit, can input the instantaneous pressure filter, C2, R2, C4, C3 step-down circuit, L2 varistor and filter circuit is composed of rectifier, the filter, which can effectively protect the LED by high pressure breakdown.
