Abstract: Lightweight LED heat sinks were fabricated by high-vacuum die casting (HVDC) using the aluminum alloy ADC12. Thermal characteristics of the heat sink were determined under natural convection using thermocouples and an IR thermograph, and the thermal conductivity was measured using the transient plane source (TPS) technique. It was determined that the castings were non-homogeneous and anisotropic.
