Help! How many leds for my UAS

[Labperck]

Hello, im building an UAS but idk how many leds to put in, im going to feed 4 pinches of pellets a day. It will have 5kg of rock, the size of the screen is 4" wide 6" high 1 1/4 thick





This is the air pump im going to use, its 1500cc/min

Welcome from Mexico.

1500cc per minute = 1.5 lpm so it should be ok.

Looks like you have 12 LEDs, so they are probably 1 watt each. If so you can start with those.

hello, thankyou its a great forum it has a lot of good info

i forgot to say that the leds are 3w each 660nm

Ok if you run them with 500ma then they should not be too much.

My driver its 1000ma i dont have more can i use just 6? 4? 2? Leds

[SantaMonica]

You will need to operate them in parallel: a series of 6 leds, in parallel with the other series of 6 leds. This will give 500ma to each led.

Hello again, i think its done, im running 2 three led series at 500mah is this enough? Im planning to use the other 6 leds for another UAS

Sounds like a good start.
