autocycle flasher principium circuit diagram
Neon light flasher assumed on autocycle back brand circuit diagram and work principle:assume a neon flashershown as the figureon autocycle back brand, which can increase safety in night,bring attention of the following vechiles, and flick when the autocycle brake.This set takes a neon tube that can justcircle the number plate,illuming it at night.VT1 and VT2 form a complementary instable multi-vibrator.BP1 and C3 decide vibrator work frequency.Signal voltage on RP2 is amplified by VT3 to drive step-up transformer T,then secondary induce high voltage to make the neon light. elements select:expect indicated elements type,photosensitive resistant can use M45 series,requiring dark resistant>1MΩ,light resistant<10KΩ;pulse transformer T can select E12 type magnetic coreMXQ-2000,primary using 45 circle Φ0.51mm lacquered wire ,secondary using about 1500 circle Φ0.21mm high strength lacquered wire.
