Hello everyone.
Noob here but need some help.
I have converted 2 disco light panels from the old style bulbs (christmas tree type running direct from mains) to LED's, there are 4 seperate circuits (blue, red, green and yellow) each containing 48 LED's wired in parrallel. I used 4 LED driver transformers (12v) one for each colour, each LED has its own limiting resistor.
It is supposed to light each colour in turn (a chase) via a lighting controller, now if I have the chase spped fast it works fine but if I slow the speed down I get the normal flash but I also get ghost flashes at a much reduced power.
I have tried the unit without the controller direct from the mains to each transformer and when I unplug it I get the ghost flash.
Im guessing its the transformers that are causing it when they are turned off they are allowing a small pulse through as the power is lost.
Can anyone suggest a way of either surpressing this or a different type of transformer to use (AC to DC)
Im not a spring chicken (45) and I teach so no safety issues with building my own unit/s
I did think of using one transformer and switching the output with relays but didn't really want the relays clicking.
Thanks for any help.
Rob
