Oscillator Powering 6 Modified Led bulbs
« on: Today at 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.
peace love light

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.
peace love light :)
