My intention is to make portable field lighting for a roughly 45yd x 60yd soccer field. I'm going to have 4 of these for each corner but I'm really just wanting to know, first, if I'm on the right path with how I think I need to build these things. Right now I'm not concerned with if people think there will be enough light or not. Just about the power and circuitry of it all.
First, I already have these: DPD-4545-0809 15W COB LEDs.
Specs are:
● 15W
● 24V
● 562.5mA
● 1350Lm
The COB array is 8 parallels of 9 in series. My plan is to have 6 of these per light stand.
Portable means batteries. But I also don't want to be lugging a bunch of batteries of round so my thought was to use one (1) 12v rechargeable battery with an 18Ah capacity with a boost converter.
Here's the battery I'm wanting to use: ExpertPower EXP12180 12 Volt 18 Ah Rechargeable Battery
This is the boost converter I think I want to use unless I'm told otherwise by more enlightened minds: Geeetech 150W Boost Converter DC-DC 10-32V to 12-35V Step Up Voltage Charger Module
The specs are:
● Input voltage :10-32V
● Output voltage: 12-35V (adjustable)
● Output Current: 10A (MAX)
● Input Current: 16A (MAX)
● Output power: natural cooling 100W (MAX)
● Module Properties: non-isolated step-up module (BOOST)
Now, my plan is to wire the LEDs up in parallel since there's no way I could get the voltage necessary from a battery for six of these LEDs in series. From all I've been able to find, I think I'll need to have a constant current driver for each LED (though my interpretation could easily be wrong). If such is the case, then I was considering using these: High Performance Constant Current Voltage LED Drive
The specs are:
● Output voltage: 2V - 30V
● Input voltage: 7V - 35V
● Output current: 3A (Max)
● Capacitance: 220uF
● Transformer efficiency: 92 percent(Max)
● Switch frequency: 150KHz
● Output ripple: 50mV (Max)
● 20M broadband
● Load regulation: +/- 0.5 percent
● Voltage regulation: +/- 2.5 percent
● Operating temperature: -40 - 85 degrees
So, is this all logical and realistic or am I going about this all wrong? Thank you all in advance for any feedback and expertise you can provide!
