I like ionisers, so I bought this one to see what was inside.
Initially I thought it was going to have open circuitry for more detailed exploration, but it transpired that the visible circuitry was only for a bizarrely pointless colour changing LED circuit, while the ioniser section was just a small potted module.
It did encourage me to dig around for an old schematic for an ioniser module that was actually quite a clever design where a capacitor was charged on one half of the mains cycle and then discharged suddenly through a small step-up transformer on the other half.

Greetings! Am I the only one who's unable to watch this video? It keeps loading and then I receive an error message "No connection (Play ID d7LMK0Xoy220ssyb)". I would really appreciate some help!
symbol for a sidac is like a Z with a line running parallel to the top and bottom through the middle.
the led is there so they can legally call it a lamp
how woud u clean that
Toxic gas = Botty burps… 😛
Wait, so there is ~2000V (possibly) directly referenced to the mains exposed at the tip of this unit? I mean, current would probably be pretty low, but it would still hurt to touch it, wouldn't it?
If you check the SCR again, you'll probably notice it has a built in diode, with diode anode connected to SCR cathode, and diode cathode connected to SCR anode. When the cap discharges into the transformer, a dampened high frequency oscillation happens. The SCR will probably still keep triggered while the AC mains is still high, and the "backwards" diode on the SCR will conduct the opposite wave of the dampened oscillation. Kind of like how a damper diode works on a TV picture tube, except the diode in the ionizer is intended to keep the oscillation going instead of stopping it.
…But they sell color changing LED's for cheap already?
Maybe the light is in there so it can be rated 1W? 😛
That bulb is made for reptile terrariums, so it isn't meant to "Improve the lung heart fuction" of people. Might make a tiny difference for a lizard stuck in a small glass box.
