Oscillator Powering 6 Modified Led bulbs
« on: April 28, 2017, 06:06:21 AM »
Hi all, was posting about this particular oscillator light in another thread, felt it was good enough for its own thread.
It's the basic joule thief style circuit, using gutted 12 volt led bulbs rated at 7 watts from ebay.
The bulbs did contain a boost circuit inside them, to boost from 12 volts to around 21-24 volts dc, of course i removed that circuit from each bulb, for added efficiency.
The setup really is putting out a very good amount of light.
I was previously using a small number of turns on the ferrite c-core, then used many more coil layers and increased efficiency even further.
When looking at a Phillips 40 watt equivalent led bulb in a nearby can light, it is not much brighter than one of the 6000k pure white led bulbs.
Here is a drawing and some pics.

I am also interested  in your design and would love to see a close up photo of what your ferrite coil looks like.
I already have the 12 volt bulbs and other parts.  What diameter is your ferrite core and what is the length of your 8 windings as shown wound around the core ? (Not length in feet)  Will a B7a neon work?  Do you wind both (2 ) 24 gauge wires as one or separate windings?

Hi magnetman, nice to see you.
The neon is the green one from the shack and it's only function is to protect the transistor, so yes, yours will work.
All the 12 volt bulbs used in this particular setup, have the inside circuitry removed, i could not get the led bulbs to such brightness and power input without doing so.
I'm getting tired, tomorrow sometime, i will take the close up picture of coil/core.
Also, i used clear packing tape between each coil layer.

Hi magnetman, here is a pic of the ferrite TV flyback c-core and multi layer 24awg. magnet wire coil with clear packing tape between layers.
The air gap shown in the ferrite core is intentional.

Hi all, working on a much larger and different triple ferrite tube core/coil setup.
The hope is, that this will give even greater output for the same input or the same output for less input than currently being used.

Can you tell me if the ferrite core is two sections or one.  Also what is the LENGHT of your ferrite body?
With regards to the coil itself is there an inner winding connecting to the 2K OHM resister and a separate outer winding connected to the transistor?  Are you using some sort of tube to wind the coils on then the tube is slipped over BOTH ferrite core ends where the cores can be easily slipped in and out of the tube for circuit adjustments..  That would account for your intentional AIR GAP?    I have two fly back cores I can use.  One is smaller than the other. Both are composed of twin C shaped sections.

Hi magnetman, it is the standard joule thief circuit found all over the net, which uses a bifilar coil, just like your air core.
The ferrite c-core is 2 separate sections and the way mine is setup, it works best with air gap or c-cores even turned away from each other.
That is why i'm making this new core/coil, because with this particular setup, it seems to work best with an open core.
Each c-core length, looks to be about 1-1/2".
I used some flexible, yet fairly thin plastic, and rolled a tube around a battery that is close in size, battery can be wrapped with tape to make larger former or you can even use a somewhat thicker paper for the coil tube former.
Then tack glue the end of the coil former to itself.
Then you can start winding on top of this, i used layer of packing tape between each layer.
Then the c-core can be slid in and out easily, as long as you didn't make the coil former too tight.
Hope that helps, though, based on my tests earlier today, an open ferrite core will work just as well it seems.

  I have just one question: Do you think two pre twisted together from the factory sections of 24 gauge wire 2.2 ohms each can be spooled onto the ferrite core as ONE and used ?  The wire is PVC coated.

Hi magnetman, i think it might be ok, i remember lasersaber was using that kind of wire on a ferrite core and it worked well.
I would say between 1.5-2 ohms per strand would be best for the 12 volt bulbs.
Not sure how well it will work, if you do not remove the inner circuitry, though you can try and see.
I finally finished winding the triple tube ferrite core, i used 8 layers of 24awg. magnet wire and it comes out to 7.8 ohms per strand on that large core.
Unfortunately, after a few tests, it does not work the best with the 12 volt bulbs for me.
Though it works very well for the 120 volt led bulbs, the modified ones and the non-modified ones.
I think it's the fact that when we wind a ton of turns and the large core, the flyback spikes are very high and it's a much better match for the 120 volt led bulbs.
I also raised the voltage input with this larger coil/core to 19 volts, using a laptop power supply.
Most definitely a more efficient coil/core for the higher voltage bulbs, i placed 2 of the 120 volt led bulbs in the ceiling sockets from the circuit and they are blindingly bright and using 19.06 volts at 180 milliamps for 3.43 watts.

Hi all, finding some interesting results.
I raised the input voltage even more, 26 volts input and using this large coil and am getting even greater efficiency this way.
I went back to the 230 volt-2sc5359 NPN transistor, because of using the higher voltage led bulbs again and also using the 2 neons in series across collector and emitter.
The modified 120 volt, 40 watt equivalent led bulbs are really pumping out the light, for only 26 volts at 110 milliamps or 2.86 watts.
Again, it seems removing any and all circuitry from inside these led bulbs, gives greater light and efficiency.
My line of thinking at the moment, is along the lines of Joseph Newmans work.
Meaning, if we add more copper wire, we then raise the voltage input and can still get the same output for less or we can maintain the same input and get more output and this logic seems to be working.
Your thoughts welcome.

I noticed your latest post about working with 120 volt led bulbs. You need to include a circuit diagram to interest others.  I am sure you will get many hits on your giant jewel thief setup. I still am sticking with the 12 volt LED bulbs.  My goal is to power 15 seven watt 12 volt bulbs (105 watts).  Then check the voltage and current each bulb in parallel is using along with the total watt usage.  I just completed making the coil.

Hi magnetman, good idea, i'll draw up the latest circuit sometime today.
Look forward to your results magnetman.
An interesting test might be to take a picture of the light hitting one of those cheap, dollar store white foam board sheets, at a certain distance.
Then plug in some normal, wall powered led bulbs or 12 volt direct powered, to show any differences between the two.
Since i don't have any light meters, i may use that method to show how bright this setup is.

I have a excellent lux meter but the thing is so sensitive to light it must be mounted stationary  at a point away from where the actual light source is.  Holding by hand is a no no .  Meter goes crazy.

Here is the big question:  12 volts X .5833333 amps equals 6.9999 or 7 watt LED bulb.
What is the ""CALCULATED""  true LUX value of one led bulb as above measured directly at a distance say 10 feet away?  Different 12volt power sources will give different readings, NEED A STANDARD READING,

Hi magnetman, I'm not aware of the 7 watt, 12 volt led bulbs lux at 10 feet and i see the issue with your lux meter.
That is why i suggest the white foam board method, at least for me, all i'm concerned about at the moment, is usable light for humans eyes to use, so placing the white board at whatever distance, we can compare to known grid powered or battery powered led bulbs.
The 12 volt led bulbs you have, a man said in a video, they are around 600 lumens, directly powered from 12 volts dc.
Here is a new drawing of my latest circuit setup.

Hi all, here is a couple pics of oscillator and lights in action.
I will be using the white foam board method soon, to try and show the light level output.
