Somehow I am not understanding your ost. Wideangle is a function of the type of LED.

Power and frequency are something else.

Perhaps you could elaborate with far more detail....

Tnks for reply

I tried with 3.3v it takes 55mili amps on DC

but with the hf osc I gave 1.5v and it takes 60mili amps for two diodes

back to back (hf AC)

I planed to drive 10 +10 led's with CD4017 to share the led's with single led power

give comments
