A look inside a mini ioniser lamp.

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.
