Need advice removing flickering from AC LED spotlight, if it only has one sine wave available.

Good afternoon!

I've recently wired a lighting system, where one light switch (a motion sensor) turns on two lights, but another motion sensor switch turns on just one.
Here is my wiring schematic: (In the schematic, the transformer connects to a 12V LED and the spotlight runs on 230V mains.)


The problem with this is that as shown in the schematic, the LED spotlight only gets half of the sine wave, so it flickers too much. My uncle has epilepsy, so I need to address this problem. I added a diode next to the spotlight because when I turn on the first switch, the spotlight turns on when it's not supposed to, because of the backward AC cycle.

My possible solutions could be:
1) Use an incandescent bulb for higher light inertia, but those are energy inefficient.
2) Use an SCR or a relay, which complicates the circuit and I've no real experience with SCRs.

Please let me know if you've got any advice that could help alleviate the flickering. (Changing schematic or using special use bulbs). Feel free to ask anything.

Whoa....you are making this rather complicated. Personally I would use a Philips Hue Bridge with motion detector and switch accessories along with Hue LED bulbs. Simple.

You are most definitely right, but because I had high-voltage diodes, it was cheaper to throw something together from the parts I had.
I cannot afford most options at the moment, hoped there would be a somewhat easy fix.

Most probably will end up placing a 240VAC 30uF capacitor in parallel with the spotlight. I think it will help smooth out the flickering.
