I have 6 LED strips, each of them requires 1080mA & 36V DC.
I've found a Constant Current driver which can supply up to 8.9A & 36VDC. As there is no resistor on the strip so I think it should be current driven for high efficiency.
The driver is: Meanwell HLG-320H-36B
LED Specs:
- Forward voltage: 33.6V - 36V
- Forward current: 0.9A - 2.7A
I planned to wire all 6 LED strips in parallel and use a current limiter circuit to protect each strip. So if one the strips is down, the others won't sink more current.
I want to ask is this a good approach ? And how to build that current limiter ? Any suggestion or instruction ?
As the driver is being shipped to me, I have to use it anyway. So is there any other solution that can help me light up my LED with the driver ?
Thanks.
p/s: I don't want to use separated driver for each strip because of the price & shipping fee.

The best solution would have been to add 6 Mean Well LDD-1000 ($3.50 ea) to drive each string and they all can be powered by the HLG-320-36.
Another solution is to use TI's LM3466 Multi-String LED Current Balancer for Use with Constant-Current Power Supplies
