Problem with IR sensor

Recently i brought a IR LED controller which I used to control my led strips. Question : Can I connect my Arduino directly to the DATA and GND pin and sending out IR signal using the IRremote library ? Will it work the way as I used a IR controller/transmitter to control the LED controller ? Thanks a lot.

You should be more specific. There is no way to, positively, answer your question without a data sheet or other documentation of the controller.
