Lynx Joule Inverter

[Lynxsteam]

I am really excited with this circuit for its simplicity and function.  I don't know of any other way to get this much light for so little power.

I had put all the electronics away in a box, quite content with the LynxJouleLamp lighting my front yard and garage off the DC converter.  Then you guys keep exploring and doing intriguing things.  I tried the Crossover circuit, maybe I did something wrong but the light is not very useful, and multiple bulbs kills it.  Got me thinking though, drawing yet simpler circuits. 
Last night I stumbled on something after hours of moving wires, jumping to this diode and that capacitor, trying this transformer and that....

Lynx Joule Inverter recipe
Ingredients:
Transformer.  I have used 1:1, 2:1, 10:1, 20:1, audio, radio shack, ECore and they all work. 
A 120 volt LED bulb or a couple. 
9-12 volt battery.

These bulbs wont light on 12 volts but they may flash.  That's the key.  They propagate the field in the transformer.  The hz is running at 168, amp draw is .017-.050  Its interesting because these bulbs are rated for 120V AC and 48ma.  So these bulbs are running on 1/10th the voltage.

I'll do a video later today and post here.  I'm calling it the Lynx Joule Inverter because it does what an inverter does, and acts like a Joule Thief.  No transistor, capacitor or resistor needed.

Hah... I think I get the idea.  Very nice! The LED lamp itself is causing the oscillations that make the transformer effect work with "DC" supply. You hook up the battery to the lesser-turn side of the transformer. This causes a current surge that makes a voltage spike on the primary that is enough to flash the bulb which causes a further current draw, dropping the input voltage, dropping the output voltage, turning the light bulb off.... which causes another spike which causes another current drain on the battery.... self-oscillation, maybe !

I think this will require knowing the exact make and model of your LED bulb.... and might also be affected by cliplead inductance and connection security, and ghosts, for all I know.

I am just speculating, and I'm about to go out to buy one of those bulbs.... Please ....what's the spec on the bulb??

Here is the video of the Lynx Joule Inverter.  I show it running 1,2,3 bulbs off several transformers.  These bulbs always baffled me because they draw too much power off SJR3.0, and the LJL.  But look what they do off a simple transformer!
I am sure brightness can be affected by turns ratio and the transformer resistance.  Each transformer I show has a different characteristic.  If you see flicker just reverse the secondary.  If you do wind a transformer pull out several taps and number the turns.
Positive 12v to a primary lead, other primary to bulb, secondary to bulb, other secondary to ground (negative 12 v)
Have fun!

Hi Lynxsteam,

What you have discovered is an automatic governer for electrical systems with an extremely simple circuit. Well done, I am very impressed!

I have been focusing heavily on this technology principle for alternative fields and slowly bringing this knowledge into the community. It is an essential principle for automatic control of a system, effectively hunting:

Governer technology is extremely important, I will have to think about the potential applications in electrical fields, but it is the same as automatic control over pressure and mass flow of a fluid, or in this case voltage and current.

Watching this with interest, keep up the good work!

The bulbs are either GE or Philips (maybe others).  Philips 3W LED and GE 3W LED use the same electronics base made in China LED3A15/C 100-127 v 50/60hz

They run poorly on SJR or the LJL circuits.  Big amp hogs.  But they run very nice just off just a transformer.  Everything is cool, no ringing, low ma.  The circuitry in the bulb is turning the DC on and off.  But once that starts the L1 and L2 start oscillating.  Depending on the transformer Hz can be 168 and up to 1000.

Positive 12 v to primary, other primary to bulb, secondary to bulb, other secondary to negative 12 v.

If you get flicker reverse the secondary.

I think with some tinkering we can find the right number of turns, resistance, and turns ratio for full brightness.
