Abstract
A heat sink includes an extruded component, a cast component, and an interface layer. The extruded component includes a first aluminum material and is configured to be coupled to a solid state light source. The cast component includes a second aluminum material overmolded onto a portion of the extruded component to form the interface layer. The interface layer is formed of at least one of the first and the second aluminum materials and abuts against and couples the extruded component to the cast component.
