Abstract
An automotive lighting assembly cooling system includes a heat pipe with an evaporation area proximate to a heat generating component, such as a Light Emitting Diode (LED), and a condensing area located remote from the evaporation area. Evaporation of fluid within the heat pipe transfers heat away from the heat generating component. The efficiency of the cooling system in one embodiment is increased by including fins associated with the condensing area and placing the fins in an area where air flow external to a moving vehicle assists in cooling the fins.
