Control LEDS with Volts

I have a potential project but have hit a snag,
I want to replace a 12V halogen lamp with a LED - There is already
provision for dimming the halogen by varying the voltage, and a voltage
slider is already in place, so is it possible control a LED or a LED
array with an analog voltage (say 4-12V) - is there a device that will
convert the voltage variance into current variance and allow me to dim
the LEDS using the slider?
Cheers
Tim.
