I need to mount a single LED with sufficient heat sinking into the base of an E10 Edison screw thread bulb.
I've collected some lovely French lamps. Historically, these would be powered by a bottle dynamo. My intention is to power them using one of the... um... 10 or so hub dynamos that I own. Old incandescent bulbs don't light up much so a LED upgrade is in order. Experience has taught me that commercially available LED E10 Edison bulb upgrades are OK, but I think I can do better, especially with the selection of high power LEDs now available. Power LEDs get hot, so whatever retrofit I come up with will need to be able to deal sufficiently with the heat.

Thus far, I think I have an idea involving a turned copper pillar of some sort that can be pressed/epoxied into an E10 bulb base. Something like this:
|Copper pillar LED heat sink|
|MES/E10 lamp base|
There are several elaborate methods described for doing this. Lambda Lights seem to have mounting LEDs directly to a large copper heat sink down to a science, so I might contact them before attempting to reinvent the wheel. From what I can tell, they turn a copper pillar and then machine a square nub on the top where a PCB is mounted with a slot milled in it so the nub can poke through and be soldered directly to the thermal pad of the LED. Something like this:
While ideal, this solution may be cost prohibitive...
