Joule Lamp

[JouleSeeker]

Welcome, Triffid.

Lynxsteam sent a copy of his latest build, featured in the most recent vids (see above) -- thanks, Lynxsteam! very glad to do testing.  First results (AIR core only, AS sent), lighting up SIX LED bulbs of the corn-cob variety, as before:

DIM setting on switch:
12V   .567A  6.8W    4110 Lux  493 Lum  73 Lm/W
11V   .484A  5.3W    2960 Lux  355 Lum  67 Lm/W
10V   .404A  4.0 W   1920 Lux  230 Lum  58 Lm/W  61.4 kHz  (I started taking freq's)

BRIGHT setting on switch (full secondary in use):
12V   .896A  10.8W   7830 Lux  940 Lum  87 Lm/W  34.0 kHz
11V   .750A  8.3W    6150 Lux  738 Lum  89 Lm/W  37.5 kHz
10V   .622A  6.2 W   4540 Lux  545 Lum  88 Lm/W  41.2 kHz

Clearly the efficacy is better with the Bright setting -- and the bulbs are BRIGHT -- 940 Lumens at 12V and 10.8W.  This is pushing the bulbs a bit; spec'd at 1.5W each (9W total) for these particular bulbs.

Next, I'd like to add my ferrite rod(s) -- Lynx, how do I remove the bottom end cap -- is it a press fit or glued?  (It seems tight...)

  Guys:
  I thought that you might like to see my version of the Joule Lamp.

  It is lighting a warm white 13 watt CFL bulb, wireless, and can also light Led bulbs, Neon bulbs, and florescent tubes. It can light several CFLs, even with their internal circuit intact. No need to tune anything, just press the on/off switch to turn it on.
  It will be a Solar Exciter circuit that will be connected on to tiny 12 volt solar panel, and 12v 4.5 ah battery. The lamp will also run off of my homemade batteries (carbon/aluminum cells). It is connected to a regular 9 volt battery in the video below.

  My camera battery is bad, and will only allow me to take a 30 second video, but that's better than no video at all, I suppose.

Well done, Nick!  A lamp that uses ordinary bulbs yet runs efficiently off of 12V DC.

  Thanks again to Lynxsteam for sending his latest smaller version for testing using the light box.  I discussed some results earlier; this morning I inserted ferrite rods (1,2,3) and recorded results.  I also made a short vid.  Then 4th of July activities happened (fun with family!), hence a delay.

   Long story short, this latest version operates very much like the previous ("cranberry" version) and with three ferrite rods inserted, the efficacy rises to 113 lumens/watt -- about the same as the 114 Lm/W observed with the cranberry (larger) version.   Tomorrow I'll post the vid.   More compact and still very efficient! 

Congratulations again, Lynxsteam, for a fine device!

Nick, great work and it looks nice!  Show off some more with a video of what you can do with the exciter.

Update on the LJL:
Now that I have designed this latest compact LJL 5.0 that brightly lights LEDs or can run at half power, I am having problems with the start switch.  The flip switch doesn't work for power on and off.  The solution is a slide switch.  It simulates touching the positive wire to the battery.  The dimmer works with a flip switch or a slide switch.

 Hello guys.


I was invited here to ask about the mini version of this system. Can it be adopted to a matrix of led strings? I have gotten myself 2 full bags of 3.2 volt 24 ma 30000 mcd led's. I wanted to make a full lighting set for my scooter that includes everything like head lamp to turn signals. With my other projects going now this will fill the bill on the other side of my scooter.

Since you guys have been working so hard on this end I was wondering what setup would allow me the most efficient driver for my lighting needs.
