Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent high frequency transformers design, circuits design, Regulated Flere
I'd suggest using the any SMPS module for AC-DC conversion then using a LM2596 obtain 5V 3A. For driving the LEDs you can use MOSFETs & an LM1117 for driving the WiFi/MCU presumably the ESP board. I am building a simi Flere
