Joule Ringer!

Lynx's latest video Lynx Joule Lamp V 3 - YouTube
I wonder what kind of bulb he has to draw 120W for 6 bulbs. Very simple circuit

@Jules

Interesting video.

On Battery: He said the system was using 18Watts which would equate to 1.5amp draw and he was showing 5+ volts on the output from the lightbox.

On House AC: The meter showed 010 for amps (1.0amp?) and 119-120 (11.9-12.0watts?) for the watts and he was showing 4+ volts on the output from the lightbox.

He didn't mention what the lights were rated, were those 2.0-2.5watt/110v LEDs?

Just curious because there seems to be some information missing to summarize.

Thanks

From HitmanMob1: Ringer circuit drawing only 34mAs? Using only the transistor and a cap, off of a 6v battery. Can that really be the case?

P.S.
NO, maybe more like 100mAs, or so, check the comments below the video. Who knows what the actual draw may be. But still impressive if the battery lasts a long while.

Hi Nick,

Don't be surprised.

I can "light" a 220v 1.6w led build on just 5.4mA.

I feel this is more a joule thief.

Mind you the lamp is just lit!

Right -- this is why it is important to actually measure the light output with a calibrated light box IMO.

Nice work, Totoalas! I like it.

OK, I've done a vid on a few more tests:
SJR2addCapVaryV.AVI - YouTube

Nothing spectacular, but lots of fun and I hope educational also.
From my description of the vid:

More experiments on my replication of Lasersaber's super-Joule-ringer 2.0 (described at Laserhacker.com). Here I add one 82 pF cap across the LED lamp (a test recommended by Lynxsteam-- thanks!). I also show the effect of varying the voltage on the current draw and on the light output. At 17V input, the system reaches about 70-72 Lumens/Watt. One hand on the voltage control, the other holding the video camera... Happy experimenting!

Penno64:
Thanks for your input. The fact that you can even light the bulb on such low current is of interest. I'm still working on the Exciter circuit with the hope of being able to do something very unconventional. As lighting 5 watt bulbs on 4 watts of power, or so, is not my idea of real savings. Or Lynx's 120 watts draw for 6 bulbs? Those figures may be off by a bit, or maybe not.
I'm not good at numbers, but I can sure tell if the light output serves my needs.
Hitmans video is another error, as he is not using just 23mAs. I wish he was.

I do like totoalas vid showing all the bulbs lit off of the 12v 7 AH batteries, and being portable as well. Might get a little heavy after a while though. Ha!

K4zep

I finally got Lidmotor"s K4zep circuit to turn my 120 volt LEDS on. 6, 2 Watt bulbs are not registering any amp draw at all at 12 volts at full brightness. The 12 to 120 Radio Shack transformer's ringing and the 2n3055's not even warm. Drew 50 milliamps at 6 volts. No change in amp draw with the addition of 5 more bulbs. The 6 bulbs grow really bright with 12 volts and the amp draw drops to near zero! I'm a bit dizzy from the results so far. This circuit looks like the best one so far. I'm boxing it for the sailboat.

[NickZ]

Allen:
Those results sound more than amazing. Please upload a pic or two when you can, and some more info to help anyone that wants to replicate that circuit. I'd be nice to know what that set up will do running off of a 12v battery, and for what amount of time.
Good luck with further tests.

Boxing up the ringer

I finally got Lidmotor"s K4zep circuit to turn my 120 volt LEDS on. 6, 2 Watt bulbs are not registering any amp draw at all at 12 volts at full brightness. The 12 to 120 Radio Shack transformer's ringing and the 2n3055's not even warm. Drew 50 milliamps at 6 volts. No change in amp draw with the addition of 5 more bulbs.

I'm boxing it for the sailboat.

That is good news! I am getting to ready to box up my boat light also. I have to make a few decisions about the final circuit but I am going to use the Radio Shack 12v transformer, a 2N3055 transistor, and a 7.5 watt led bulb. You probably need to check your power consumption again because this circuit is no free ride. I'm going for about .5 amps at 12 volts with good light. It is pretty simple-----it has to work better than any of my other lights or I just won't use it at sea.

My son and I are setting up a place to run on solar + 12V batteries, completely off-grid. So we are very interested in these developments -- thanks Lidmotor and all!

I used the light-box described above to test various bulbs, as shown in the photo attached. The bulbs at left, running at 120V off mains, deliver typically 55-70 Lumens/Watt. The bulbs on the right are designed for 12V DC operation, and deliver about 30 - 65 Lm/W.

The bulb second from the right is turned so that you can see some of the electronics components -- which were left exposed for this 12V bulb with six LED's. Touching the back, I picked up a frequency of 304 KHz, so evidently the circuitry with this lamp goes from 12V DC to about 304 KHz AC -- probably using a blocking oscillator. This bulb puts out about 62 Lm/W running on 12V DC.

As described above, my replication of Lasersaber's 2.0 build resulted in about 72 Lm/W from LED bulbs (so far) -- which is somewhat better than what I typically can get using the mains or the 12V bulbs.

[Slider2732]

@PhysicsProf - There has been much talk within YouTube comments, I note, on the driving frequencies and 'perceived' changes to the running of LED lamps. It can be expected that the high Lumen 304KHz bulb has been the subject of a good amount of R+D to gain that figure for driving it. Do you have a frequency generator that could drive that lamp (or others) at different frequencies ?
I'm just wondering whether to build an oscillator that is tuned for ~300KHz
Thinking about it, is it likely to be pulsed DC, rather than AC ?

Hitman's boxed solar unit

@All
"Hitman" on Youtube has boxed a nice simple unit that gets the job done. This video kinda shows what most of us have wanted ever since Lasersaber showed that first Super Joule Ringer long ago. It is an easy to make inverter that powers a bunch of AC led lights in parallel in his "shed". The circuit that he is using is very similar to what I ended up with except that I am leaving in the red led indicator.

SJT2.0 Solar Power Inverter - YouTube

@Dr. Jones
Thanks for all the light box lumen testing. That helped.

@ Slider
The frequency and wave form of this circuit is still a puzzle for me. I spent several hours looking at this on my o-scope. It was confusing. It isn't just pulsed DC. It is AC but not a sine wave. The frequency is way up there in the kilohertz ---at least with the bulbs I tested. The circuit inside the bulb is a major player in the main circuit. Different bulbs do different things. Some don't work at all.
