Abstract
Lighting modules combining top-contact LEDs and surface mount LEDs are described. The top-contact LEDs are mounted directly to a heat sink and are electrically connected by ultrasonically bonded conductors to a PCB containing the surface mount LEDs. The modules may also comprise a lens assembly configured to combine light emitted by the top contact LEDs and the surface mount LEDs into a composite beam.
