The defrost structure for a vehicle headlight is provided. In the defrost structure, an LED 2 arranged in a housing 10 is connected to a heat sink 20 through a heat pipe 40. The heat sink 20 comprises a base plate 21 closing a rear opening of the housing 10, and fins 22 erected on the base plate 21 vertically to protrude forward in the housing 10. An air flow channel X is formed to allow air warmed by the fins 22 to flow toward an inner surface 11a of a lens 11. An upper side 22a of each fin 22 serves as the air flow channel X. |
