]]> This is a 220V LED flasher circuit which is intended as a reliable replacement to thermally-activated switches used for Christmas tree lamp-flashing. This a low cost circuit and easy to built since it only use little amount of electronic components..

Schematic diagram:

220V LED Flasher

Component Parts:

R1_________ 100K
R2,R5______ 1K
R3,R6______ 470R
R4_________ 12K
C1_________ 1000uF 25V
D1-D4______ 1N4007
D5_________ SCR  P0102D
Q1_________ BC327
Q2_________ BC337
SK1________ Female Mains socket


How the circuit works:
The device formed by Q1, Q2 and related resistors triggers the SCR. The flashing frequency is provided by R1, R2 and C1. To change flashing frequency value, just? set C1 value from 100 to 2200uF, don’t modify R1 and R2.

Best performances are obtained with C1=470 or 1000uF and R4=12K or 10K. Due to low consumption of normal 10 or 20 lamp series-loops, very small and cheap SCR devices can be used, e.g. C106D1 or TICP106D.

Warning! : The circuit is directly connected to the 220V mains, please be careful when try and use this circuit
