Hey guys just looking for some ideas on the easiest way to make a 24 hour lighting program with about 3 or 4 outputs using PWM dimming for Leds
I would also like to be able to adjust the overall brightness.
was looking at using a 24V switch mode PSU, suggestions appreciated as to how to get an ideal voltage cheaply?
with power through a FET with the signal controlled by the microcontroller or whatever
looking to make this as efficient as possible, also some stats on the leds
Vf 3.4
Led current average from 0 mA to 1000 mA with 50% max duty cycle still sorting out heat sinking so its a rough guess.
number to be controlled X number of banks of 24 - 30 leds pretty much whatever fits with the power supply voltage so I don’t waste power in resistors.
As a reference looking to make something similar to the Solaris led reef lighting system.
Cheers Andrew
