Copper-subtrated LEDs show better efficiency in research

[SeanHatfield]

I just read this blog article:

And wow, i can't wait for Copper-substrated LEDs to become mainstream! Let's hope the 122% efficiency boost stays the same

with high-power LEDs.

Too bad it will probably take some years to get ready for the LED market...

Just had to share this

Interesting, but would need to see the whole paper to understand how this improves on state of the art.

Based on the limited information in the article, I am not sure this is an improvement, at least in efficiency, over back-thinned flip chips LEDs such as made by most of the majors these days. This looks like an alternate approach that achieves similar advantages and perhaps adds some new ones.
