Led headlight heat dissipation device

Abstract

A headlight heat dissipation device includes a headlight casing which has at least one hole and at least one metal-made and heat-conducting unit covers the at least one hole. The at least one metal-made and heat-conducting unit includes at least one slot which communicates with the at least one hole. A water-proof and air-permeable unit is mounted to the at least one metal-made and heat-conducting unit and covers the at least one slot. The at least one metal-made and heat-conducting unit has an extension portion located in the headlight casing and the extension portion is connected with the light source so as to transfer the heat from the light source to the at least one metal-made and heat-conducting unit to quickly bring the heat away from the headlight casing.
