I am working on a school project of creating a LED bulb that works on standard 110-120 VAC. The bulb should serve as a viable replacement for a 60 incandescent bulb. The plan was to run the 120VAC through a 2:1 transformer, then through a rectifier so that the output would be around 60VDC(this will serve as the input to various components and the LED driver). I am having trouble finding a transformer that will meet the desired space requirements (very compact) and still meet the voltage and current requirements (60VDC & around 1.5-2 amps). I suppose i could just place a large resistor in line before the rectifier, but this seems to be very wasteful. Can you help me find another method to step down the voltage efficiently.
Thanks in advance
