u r right. n whar u r talking about is to apply PWM to LED. but in that case also you can not apply more than rated current (absolute max rating) to LED. IR LEDs have around 50 mA current rating. so with 5V input and around 100 ohm resistance in series will lit the LED with full brightness. and it gives max range.
