With the developments in GaN-based material technology, high visibility white light emitting diodes (LEDs) have flourished over the past few years and have proven very promising in many new lighting applications such as outdoor lighting, mission and decorative lighting as well as aircraft and automotive lighting. LEDs are semiconductors which use the phenomena of electroluminescence that in general refers to the production of light on the recombining electrons and holes within a material. The challenges of thermal management in the automobile sectors are growing wider for large utilization of high-power LED lighting installations. The objective of this paper is to explore an active liquid cooling solution of such LEDs in an application for automotive headlights. In this work the thermal design was carried out from computer to board to system level. Air cooling and passive liquid cooling approaches were tested and ruled out as unacceptable, and an active liquid cooling solution was therefore selected. Many active liquid cooling system configurations were tested, and optimization research was conducted to find optimum thermal performance.
