i tried to make a stroboscope with 50watts high power led and an arduino board. i success to do it but the problem that i faced that the lumen of the led becomes very poor because of the short on time duration (100 microsecond). So how can i solve this

The only way to brighten up the LED more would be to increase the amount of current going through it, which could easily blow it up... Why don't you use a xenon lamp instead?

Get a faster LED. White LEDs tend to be very slow because they use a phospor to produce white light from a blue or UV emitter. Check the datasheets, you may find that for your application white LEDs are unsuitable.

 

Or increase the duty cycle of the current through the LED. If the duty cycle is 10% you effectively get 10% of the light. If it is 15%...

It is a painful trade-off. As they say, there is no free lunch.

You might find this thread useful, where we discussed much the same issues. The bottom line (for me, anyway) was that even the highest-powered LEDs aren't very well suited for strobe work because their light output comes nowhere near that of a traditional xenon flashlamp.

Get a faster LED. White LEDs tend to be very slow because they use a phospor to produce white light from a blue or UV emitter.

I initially assumed that, too, when we started working the issue in the thread I mentioned above; but subsequent tests with a 3W LED showed rise and fall times well under a microsecond, with no discernible "tail" at all in the light output.

There are phosphors and there are phosphors, but at least the one used in the 3W LED I tested was pretty fast.

The problem with increasing the duty cycle is that instead of stop-motion, you wind up with a smear.

 

I made a stroboscope using an automotive timing light. They are cheap second hand

even new they are reasonable
