Photonic Lattice LEDs are new class of light-emitting device

A bit older, but LEDsmagazine had reported new Solid State LED lighting technology:

Using photonic lattice technology it is possible to build large-area chips that enable ultra-high power sources for projection and other applications, writes Robert Karlicek of Luminus Devices.
The term “power LED” usually describes one of two types of LED assemblies: a conventional 1 mm2 power chip in a power package, or an array of chips (1 mm2 or smaller) combined in one of several different types of power packaging formats (semiconductor chip(s), package, encapsulant and heat sink).

While the performance of power LED devices has improved dramatically over the past 10 years, the basic concepts haven’t changed too much over the past forty years: one or more small LED semiconductor chips attached to a metal packaging structure and covered by an encapsulant/lens to help extract and shape the light output.

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.

Now a 100W per package is impressive no doubt, hopefully this finds itself into the LED Grow Light segment soon.
