Abstract
The LED headlight heat dissipation device includes at least one metal-made heat-conducting unit mounted to at least one hole in the casing of the headlight. The at least one heat-conducting unit has a higher heat transfer coefficient than that of the casing. The at least one heat-conducting unit is in a form a plane, or is engaged with a hole, and has different shapes such as cup-shaped, rack-shaped, board-shaped or fin-shaped to increase the contact area between the casing and air in the headlight and the source of heat, so that the heat is brought out from the casing. The at least one heat-conducting unit is directly connected to the source of heat of the LEDs by an extension portion to directly transfer the heat of the source of heat to the at least one heat-conducting unit. A water-proof and air-permeable unit is mounted to openings of the at least one heat-conducting unit so that the air is permeable through the water-proof and air-permeable unit while water cannot enters into the casing. If the casing has holes in the top and the bottom, the hot air escapes from the holes in the top and the cold air is introduced form the holes in the bottom of the casing.
