Micro-channel heat sink for LED headlamp

A lamp for a vehicle, the lamp comprising:

• a lens attached to a housing, the lens and the housing defining a volume;
• a heat sink at least partially disposed within the volume, the heat sink comprising:
• a base plate including a first side and a second side;
• a leg extending from the second side of the base plate, the leg including a distal end opposite the base plate;
• a leg plate disposed adjacent the distal end of the leg;
• a plurality of fins arranged in the distal end of the leg and disposed between the base plate and the leg plate;
• a plurality of micro-channels defined by the distal end of the leg, the plurality of fins, and the leg plate;
• and
• a light-emitting diode attached to and in thermal contact with the first side of the base plate,
• wherein the plurality of micro-channels allow a fluid to be in thermal communication with the volume;
• and
• wherein the leg plate is directly fastened to the leg wherein a cross-sectional area of the leg plate in a plane perpendicular to the extending direction of the leg is less than a cross-sectional area of the first side of the base plate in a plane perpendicular to the extending direction of the leg.
