Induction lamp with no vacuum

Induction lamp with no vacuum

Click to view full size image

This induction lamp unfortunately arrived with the amalgam reservoir seal broken off. I tried to vacuum it down and give it a fill of argon to see if it could be coaxed into doing something. There must be a better penning mixture as I could only get flashes out of it.

Probably it broken during transport.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I'm antiLED and hope that the LED lighting will be phased out in favor of old lighting technologies soon.

Indeed, I found the reservoir was loose in the box and there were a few puncture marks in the packaging

That is a shame, Mark

Can you get an exchange or refund?

Pretty, please no more Chinese failure.

Isn't it supposed to be operated above some conductive sheet (= external starting electrode)?
I would guess the small mercury pressure of the original fill will provide quite some help as well...

Just got it so waiting to hear if they can replace it. I've generally been quite luck this is the first broken lamp in ages. Still manages some experiments with it so far.

Is there solid Amalgam in the reservoir ? Would be interesting to see if you can manage to throw some into the lamp and see if THAT would do something, if you get good enough discharge to evaporate the Mercury out

If you add a HV starting antenna (few turns of bare wire around the side of the tube, far from the induction coils, and connect it to some source of AC HV or pulsed HV) i think you might be able to get the lamp started with nothing but low pressure Argon inside

Not sure if there would be external start assistance from a grounded reflector. The wires to one of the coils are taped along the tube surface so may help.
I think some mercury content may also help and I do have the metal amalgam pellet from the reservoir, so could try that. Don’t really want to pump mercury vapour out of the lamp I think I am mad enough as I am.
Did try external pulse ignition from a tesla coil to help ionise the argon but that didn't appear to help. The electronic ballast seems to look for the correct loading at each start pulse and doesn't attempt to run a faulty lamp.

The taped wires are one electrode, it may need the other one nearby. Touching the glass by hand may help...
Given the protection circuit, the external pulse will have to come exactly when the ballast tries to fire the lamp (so the field from the couplers is present), so the ballast will see the load.

And for the pumping: To minimize the mercury release, all the thing has to be cold.
But I do agree, there is quite some risk contaminating your vacuum pump and having that released every time you will be using that pump again...
