I have been working with LED lately and I encountered the following circuit.
- The bridge is DB107S 1A 1000V.
- The LED work at 60mA, 3-3,4 Vf.
- The board is connected to mains power with 230rms @ 50Hz.
The problem is that sometimes the LED's are getting cooked.
I believe that this is caused by voltage spikes that pass in the system since it does not have a low pass filter (RC) in the input.
Any thoughts or suggestions on how to identify the problem?
EDIT: The LEDs are 54 in total and not 27 as my first schematic shown.
