nope, the LED 'chips' inside are set in series that total a bit higher a voltage though I don't know what it may specifically be with these, could be 36 or 72 v for instance. also the two LED bulbs that were shown as a whole work on 220 ~ 250 volts (in the US and some other countries 110 v), and thus it does not matter what specific voltage the LEDs inside of them actually would require, the wall socket's voltage is what the bulb takes and it is stepped down to the right level (and also smoothed out) by internal components. on the other hand I must admit that the internal circuitry inside these bulbs probably can also make them work on a lower voltage than the AC power it normally would use; as long as it would at least be the same height as that that the sets (series) of LEDs (as they are mounted) in total would need, it is possible a voltage as low (but also as high) as that could simply pass straight on to those LEDs. Voltage regulating and smoothening circuitry as used on such applications - and for instance in modern USB phone chargers no matter what output protocol(s) - can be quite flexible that way nowadays (they also often take all AC voltages in-between 100 and 250)... but it definitely would have to be quite a bit more than 5 volts, that's for sure. and by the way, in the day there was another type of power saving lamps (inside of which was nearly the same tech as was used in fluorescent tubes) that REALLY would light up at nearly ANY voltage! they EVEN would start glowing when they were held under an overhead, high-up power line (be it that is electric field would directly affect the innards of that type of bulb or tube and bypass all the internal voltage regulating electronics).
That's to much work and your using a battery I can do it with just a little copper and a magnet I can do it way faster without using no welder or battery free energy my friend. You're getting to technical for some people that don't understand electronics I understand it but not everyone does .
Чанда это все 😂 . 220 вольт на выходе.? Ну пальцами трогает как будто нечего нет.😂. Я сам радиолюбитель не раз пробовал из интернета что то делать но не хрена не работает..
У Ака Касьян такая же схема из более народных компонентов прекрасно работала. Только он меньшее напряжение получил на видео с одной батарейки. Искать по "блокинг генератор".
From Wikipedia, the free encyclopedia Basis of solid-state Blocking oscillator The waveform generated by this circuit This Joule thief circuit, a blocking oscillator, can be used in order to power a light-emitting diode from a 1.5V battery for a relatively long period of time, with the brightness being a tradeoff. A blocking oscillator (sometimes called a pulse oscillator) is a simple configuration of discrete electronic components which can produce a free-running signal, requiring only a resistor, a transformer, and one amplifying element such as a transistor or vacuum tube.
beautiful! is it so little electricity that you can hold it in your hand, touching even the wires of the output without getting shocked, or is that not what that little neon indicator light is connected to?
I made it works well from the transistor D882 I used and instead of variable resistor I used 100 ohm resistor, put the resistor on the base of the transistor
@@mohammadnavidrufi first Thanks for replying. I tried to made the circuit with d882 transistor also but the transistor burned. I think my components are damaged because I have brought them from a local shop.
Hello friend. You should rigorously check the transformer terminals. It has two parts: The primary winding, that is divided into two windings, and one has more turns than the other. The one with the most turns is the main primary winding, connected between the collector of the transistor and the positive pole of the battery. And the other winding that has fewer turns is the feedback and is connected between the potentiometer and the base of the transistor. In the middle, the potentiometer acts as a bridge or central tap between the feed-back winding and the main primary winding. Then, there is the third winding which is called secondary, which is the output one. To identify each of the three windings, you must use a multimeter on the Ohms scale, in the 2kΩ range. The secondary winding will give the highest measurement. And next, the feed-back winding will show a much smaller measurement than the main primary winding. You will probably need to reduce the multimeter range to 200Ω to get a more accurate reading on the primary side. In turn, there should be no electrical continuity between any of the three windings, until before making your connections. This means that each winding is independent. The possible solution for your transistor to start oscillating may be to connect the terminals of the feedback winding backwards. You could also improve this design by adding a diode antiparallel to the transistor, with the cathode on the collector and the anode on the emitter. Why this? Well, because perhaps what may be damaging the transistor is the reverse voltage stored by the main primary winding that discharges on the transistor when it goes into a low state. So, the antiparallel diode shunts this high voltage peak to ground. I hope this helps you find the error you may be having in your circuit. Greetings from Argentina. 🇦🇷🙋🏻♂️
Polarity is one of the main conditions for parallel operation of transformers. If the polarity is reversed, there will be a large short-circuit current in the winding, even burning out the transformer. The polarity of a three-phase isolation transformer coil is mainly determined by the winding direction of the coil.
