I need to amplify the output channels of a TLC5940 to drive more LEDs.

I have been recommended a TIP107 to do this, how do I wire it up?

What you are wanting is more current drive, each extra LED requires a little more. Putting them in series will help, instead of wasting current as heat in the current limiting resistor you are using it in the LED.

You will need to provide more information, such as power supply, color of the LEDs, quantity of the LEDs.
