Abstract
High brightness LEDs are mounted directly on a heat pipe or are mounted on a substrate, which is mounted on the heat pipe. The heat pipe can be a common electrode for the LEDs mounted on the heat pipe. Multiple heat pipes can be arranged so that the LED arrays form a light recycling cavity to emit and reflect light.
