Summary:

In support of the Department of Energy ( DOE)"SuperTruck" program, a group of low energy, high outputlight emitting diode (LED) lamps were developed for forwardlighting. Reduction of the energy needs of the truck by saving fueland reducing CO₂ emissions are two of the goals of this program. Insupport of the energy reduction, a retrofit LED headlamp wasdesigned, built and tested. The retrofit headlamp was switched froma halogen bulb to an LED-based system. The LED headlamp requires anew approach in heat management. The use of the LED, which is a 2πsource, requires a different strategy in the optics from those usedwith a 4π source, like a traditional incandescent, halogen, or HighIntensity Discharge (HID) light source.A thermal management system is necessary to facilitate the longlife of the LED source. A unique method for removing the heat ofthe LED and maintaining an acceptable temperature was tested andreported. The methods used in the design and testing are discussedalong with measured data
