Light Emitting Diodes (LEDs) are being considered for use in the automobile headlamps for front side illumination in the place of halogen and xenon headlamp systems. Although LEDs provide larger service life and better power efficiency, they generate considerable amount of heat. It is desirable to develop an advanced cooling system to effectively dissipate heat generated for a stable, continuous and reliable LED operation. The objective of this investigation is to experimentally study the factors influencing the cooling performance of the air cooled heat sink model used in an automobile LED headlamp system. The cooling performance of the heat sink model under consideration was assessed by measuring temperature and thermal resistance at significant locations. The input power, fan output and ambient temperature were varied and corresponding effects were observed. The effect of power variation on illuminance was observed. In addition, a comparative study was carried out to determine the effects of forced and natural convection, which indicated the necessity of forced convection for effective cooling of an automobile LED system.
