That's an interesting concept. I wonder where it will go in the future?

I can already predict that this technology wouldn't last longer than incandescent, because manufacturer would begin to find tricks to make planned obsolescence that would cause this technology to not last longer than todays LEDs.
In the past, LED was the longest average life light source. Today, it is one of the shortest average life light source, and incandescents can outlive it very well.
Also, some american members here, posted pictures of 1940' and 1950' T12 fluorescent and mercury lamps, that are still operating at their initial brightness, and said that they are even brighter than similar fluorescent and mercury lamps models from the 2000': Any LED in the history of the electronics, didn't managed to survive such a long time.

Fluorescents have proven themselves to last a long time in some cases.  About the planned obsolescence, we will have to see what happens, I hope that is not the case though.  It does look interesting, we will see what happens.

Dor, 1940s fluorescent lamps did not last very long at all. The best most 1950s lamps could do was 5000 hours for small ones and 12,000 hours for 40 watt ones. The ones that still work have had very few hours. I will say the Mazda 20 watt white is certainly not as bright at SP35, but they matched pretty well in color at least to my eye.  But they stayed brighter longer than the mercury starved ones made now.

They look nice, can be embedded in windows etc and i guess they will be great for making displays out of

As for the issues with new light sources, they come down to this : Chip overload, Electronic ballast issues, form factor issues, proprietary vendor lock-in. Will there be such problems with the new lamps ? - this only depends on how they will be made, ot inherent part of the technlogy
