I am trying to create an LED pool light that works off a 12VAC input. Upon disassembling a similar pool light (Intellibrite), I found that they appear to be using rectifiers and perhaps a few small inductors, as well as many large capacitors.
I am trying to do something similar.
12VAC, up to 20 Amps
5-30VDC (voltage doesn't matter as the LED driver I'm using can use any voltage between 3-30VDC) Capable of supplying at least 60 Watts of power (IV >= 60)
What is the best way of accomplishing this? My goal here is efficiency as well, as well as a simple BOM (less than maybe 20 components).
I considered using full-wave bridge rectifiers, and simply putting HUGE caps on the output. However, I am not sure if this is a good solution, considering I need 10Amp output, and the capacitor values might need to be humongous.
Any IC that makes this easier is a bonus.
The LED Driver that I am considering is the LT3496 (same one I see used in the Intellibrite). Also, if there is a better candidate for an LED driver, feel free to sugggest.
- Realized the LED driver can support up to 30VDC input, not up to 12VDC.
- Corrected the requirement from 10Amps of current to Wattage requirement.
