First of all, thankyou Mr. Nigel and Optikon for the advice. Sorry if I haven't explain well this project we were doing. Let me explain.
We are group of Computer Engineering students that has a project all about IR home automation which can be programmable through a flowchart we made in Java. So far, we were able to record the IR signal from IR remote home appliances. We can now able to manipulate the behavior of the appliance connected to our device with the use of IR as our medium. Its like an universal remote in a computer that can control IR home appliance. The hardware problem now is that we can't improve the range. We were able to designe many circuits and as so far what I previous posted was the one worked for only 6ft. Thanks to Mr. Nigel, I was enlighten about the normal use of 1A in an IR LED. About the 40KHz modulation, I was already aware of that because I read some materials telling me that IR home appliance has a protocol of 30-40Khz to be able to control in far range.
Here I would like to ask everybody's comment on this circuit. Will it work in a ideal modulation of 38KHz?

@Mr. Nigel
I have read your site and its a very interesting site. I'm still trying to find information that can help me.
We don't need to make a receiver circuit because we are sending the signals to the appliances we are controlling.
Thank you very much!
