8-mode christmas controller

(1/1)

Hi,

I have a Christmas controller like the one attached (PCB marked PD-4F1-A). It seems that it uses a similar schematics like the one I also attached.

My question (maybe stupid one) is that LED's in series are connected directly to 230VDC (after the bridge without any voltage step down circuit) which is too high for a led that normally works ~4V.

So where am I wrong here?

Regards,
