Solar LED flash light circuit
Source: InternetPublisher:司马缸砸光 Keywords: LED solar energy LED flash light Updated: 2020/11/11
Circuit working principle: The flash circuit consists of three parts. The first part is the power
supply. During the day, two 1.6 V solar cells charge two AA batteries through VD.
At night, the battery GB automatically supplies power to the circuit . The flash frequency of the LED
is about
once per second, and the light-emitting time is about 330 ms.
