Conventional power LEDs have gradually evolved through incremental improvements in semiconductor and packaging materials and manufacturing processes.
Here we describe a new generation of ultra-high-power photonic lattice LEDs, which operate at input powers as high as 100 W and are orders of magnitude brighter than conventional power LEDs. These are the first commercially available LEDs using photonic crystal concepts to manage light extraction from the LED.
