It's difficult with so little info.
A 3 watt LED? Do you have a part number for this? I ask because 3 watts is a LOT of power for an LED, I suspect that you're driving some kind of LED array (or string) and how they are wired makes a big difference.
Also, if you drive an LED with a sine wave voltage, there's very little difference than driving it with a square wave. Are you trying to get the light output follow a sine-wave curve? (would have to be an offset sine wave, since there's no way to have an led generate negative light).
If you explained more of what you're trying to do, someone might be able to help you. Instead you get this useless answer from me because you didn't take the time to explain what it is you're trying to do. And I only get to answer once (YA rules).
