Night automatic lighting circuit with bidirectional thyristor

Published:2011/8/29 1:25:00 Author:Jessie | Keyword: bidirectional thyristor, lighting circuit | From:SeekIC

When the sunshine is very strong,light activated triode L14C1 will be connected. Diode VD3 is connected, which makes voltage of capacitor C2 decline to zero. Two-way trigger tube VD5 and two-way thyristor VT are not connected, the light is not on.
