LED lamp with tiny 5kV high voltage ion module. (inc schematic)

Ғылым және технология

It's both creepy and impressive that they can ram a tiny little high voltage (about 5kV) power supply that runs directly from the mains supply into such a tiny space. Because the current required is small they use a very simple capacitor discharge system to pulse the primary of a very tiny transformer.
I tried this module on 110V and while it did work the output was much lower. Theoretically all they need to change in the design is the value of the two input resistors, so they probably do a 120V version.
This video also introduces a specialist component called a SIDAC. Basically a self triggering shunt device reminiscent of a diac, but specifically designed for pulsing things like ignition transformers.

    Buy a "blank circuit board" perfboard with holes and copper traces to practice soldering on. It's easy but the practice really really helps. The part you don't ruin (you *will* ruin at least part of it, we all do) will be useful to you later on to build your own designs on.

    Excellent! Best wishes on your assembly! It's all about practice and developing a feel for how molten solder behaves. A little note on technique... It helps to have the iron a bit hotter than you might expect and to work quickly. You want the pieces you're soldering to have enough heat themselves to melt the solder so don't look to the iron to be what you melt the solder onto. Get in quickly with firm metal to metal contact for good heat transfer to the work, apply the solder to the surfaces you want to form the basis of the joint, and get out quickly before you apply enough heat for it to spread up the component leads and damage things. You may also want to get some no-clean type liquid rosin flux to supplement the bit of flux contained in the solder. I use MG Chemicals rosin flux www.digikey.com/product-detail/en/mg-chemicals/8351-125ML/473-1412-ND/9658014 and it's the difference between exceptionally easy soldering and having an impossible time. Welcome to a new world. 😎

    Traps for beginners with those cheapie clocks: 1 The pads are really tiny and easy to rip off the board. Cut one leg at a time and do it very carefully. 2. be careful with the polarity of the LEDs if it has them. The circuit board or the instructions may not be very clear, or just downright misleading. 3 if something doesn't work you learn far more by figuring out why than you would if it just works first time, and problem solving is a rewarding skill. 4 take your time and have fun

    Another great place to find carbon fiber cords is to save your old spark plug wires when you replace them, if you're driving a car that's got a distributor and not coil-on-plug ignition. The high voltage wires coming off the ignition coil to the distributor, and the ones from the distributor to the plugs, are typically a similar sort of silicone-insulated carbon fiber to what's useful in ionizers, and can be used pretty much exactly like that carbon heating cord wire.

    Interesting video. You can also use a neon bulb in place of a sidac, which fires at about 90 volts. I built them decades ago in High School electronics class, where we made our own resistors using graphite (pencil 'lead' rubbed on paper), and capacitors out of wax paper and aluminum foil. The whole thing was referred to as a 'relaxation oscillator'. The rate of flash is determined by the RC time constant...

An explosion needs pressure and a sudden rupture of the containment, which then releases all of the built up pressure at once. The Tchernobyl reactor "just" heated up so much, that the containment building and the floors melted away, which resulted in a huge splatter of radioactive, way overheated material.

    If anything that resistor will be of a small value so it is still a good ground reference unless you're passing lots of current. My Weller WAD101 measures 30ohm between the tip and main earth pin on the IEC socket.

    A sidac is the alternating current version of a diac. In the case of USB ionizers run from 5V mains adaptors, the adaptor normally have a class Y capacitor and a 10M resistor across the mains isolation barrier. The 10M resistor should act as a ground return preventing excessive voltages building up.

    I rarely see the resistor used in USB power supplies. Unfortunately the ioniser modules can cause a significant voltage across many supplies and cause insulation failure. A diac is bidirectional by default as it has to trigger a triac gate on both halves of the sinewave.

    Oh wow, that SIDAC is super interesting! Definitely seems like the perfect, simple component for generating high voltage circuits, which it is... haha It's a heck of a lot easier than trying to make and tune up something like a 555 timer or a few overheating transistors to generate HF pulses, which is one of the only ways I've seen it done for goofing around with HV stuff. Although, the drawback is definitely clear if you needed like, feedback to generate resonance. Also, I thought that ceramic capacitor was a piezo for a second, lol. Edit: Wait... I suppose you could manually tune the SIDAC with a variable resistor.... 🤔

    An alternative to the SIDAC is a thyristor. There's a very similar circuit that charges the cap on one half wave and then discharges it on the other.

    So a sidac is basically a higher voltage diac. I think one of the main reasons for those 22K input resistors is to keep the sidac from shorting the input supply when it triggers. The input voltage will likely be near peak when the cap charges up to the trigger voltage.

  • @timkeip

    That might actually be a diac (which is a half wave sidac) Diac's are relativity cheap on ebay (at least they were 5 years or so ago when I purchased some) . It would be interesting to look at the wave form on the transformer primary, you may find that the pulse frequency is much higher than the line frequency. I have a guess that the circuit is operating as a relation oscillator at a higher frequency, that would also work better with the small capacitance on the output. Many years ago I used to build power supplies (zappers) with a neon lamp relation oscillator, the transformer was a 'backwards' audio output transformer so it wasn't in the kV range but was a healthy zap. Interesting video, thanks! BTW- That's an interesting safety line power connector... Most of my work is done with a "Widow-Maker" (an old power cord with clip leads attached [don't try this at home kids ;-) ] )

    Graham Langley, SIDACs are like a big, heavier duty DIAC, typically with higher breakdown voltage and higher power rating. Both of which are in the Thyristor family. Check out all the various different types ... most are use-restricted to high power things, for example, GTO (Gate Turn-Off thyristor) and such: en.wikipedia.org/wiki/Thyristor#Types P.S. Ever heard a musical train? Here is a Japanese EMU (Electric Multiple Unit) with the classic singing VVVF inverter, based on GTO: kzread.info/dash/bejne/dpOA27moZba4eqQ.html The sound changes when the voltage (VV) and frequency (VF) is changed.
