Finnish designers won the Luminord contest with the following design led lamp. The lamp moves when getting warmer.

"Translation":

"Lamp consists two layer metalsheets which will straigten when heated up to 77 degrees Celsius and the sheets will bend down when reaching the room temperature, 22 degrees Celsius"

nice idea but the surface area is realy small and i dont think the cooling from a bi-metall moving will be enugh to keep the lamp in movement (it will unfolde and than stay that way until turned of. waht i think the desinger wanted to do is have it so the bi-metall bends and beacuse of the movement cools down inturn bending back to its original shape... and repeat)

I don't have the best view of the lamp, but in concept it doesn't look any different than the alu bars we are using now, and those are perfectly adequate for cooling LEDs spaced half a foot apart.

The only difference with this design is that the bars flex when heated. I wonder if it's that nickle-titanium alloy, aka memory metal that was all the rage in science books about 20 years ago. When heated it reurns to it's original form and gets pliable when cooled.

Anyways, the flexing just looks like part of an aethestic thing and has no function.

Looks pretty nifty to me. Somebody is obviously not wasting their time trying to figure out how to cram the brightes LED into an incandescent socket.
