IR Strobe ???? Please help

[Frank]

I have been trying to build an Infrared strobe. I have been able to make the
diodes flash off and on using a 555 timer circuit. But I can not make them
strobe....I'm missing something here ????
What do I need to do to make the IR diodes STROBE BRIGHTLY not just turn off
and on ( I use Night vision equipment to see them). I purchased a real IR
Strobe (40 dollars) but its encased and I can't determine how
they made it strobe very brightly with just 3 diodes and a 9v battery. I'm
sure I need to hit the diodes with either a much larger voltage than normal
or something...
Any help would be great.

thanks
Frank

LEDs just turn on and off.
You get the most brightness when the maximum current is driven thru the
LED.
You can find the max current in the LED datasheet.
Perhaps you need brighter LEDs.

No.
