I Have found the Above LED drivers. Datasheet can be found at

I would just like some advice from the powers that b, Do I need to add anything else to this circuit or just my LED array with the incoing DC supply through the driver to the LED's.

 

Do you intend on doing PWM dimming? If so you need a device which will output the PWM signal.

Other than that its just a constant voltage power supply and the meanwell LDD device.
The power supply must be greater than the combined max forward voltage of your series LED string.

 

No dimming. I was just woundering if a current limiting resistor needed to be added. I assume thats all taken care of in the driver.

yep an LED driver is so you don't have to waste heat/efficiency with a current limiting resistor.. The driver does its own current limiting.
It essentially turns your "constant voltage" supply into a "constant current" supply.

 

Thanks very much. I bought some LED lights from Chna 10 mins and all the drivers started flickering and one by one they failed. When I opened the drivers the IC's surface mount and various other components had actually fallen off the boards. The LED's are on I just need to find what the current limit and Supply voltage is now. Zimbabwe is the dumping ground for cheap china junk

The whole world is the dumping ground for cheap china junk. Sadly no one wants to pay (or has the money to pay) for quality products anymore.
