I am relatively new to electronics and I am trying to turn on a Bridgelux BXRC-50C2001-D-74COB LED (Digikey listing, Datasheet ) using a 500mA Mean Well DC-DC LED Driver (LDD-500LW). The LED Driver is powered by a Mean Well 24V AC-DC power supply (IRM-60-24ST).
I've hooked up the LED Driver control wire to an Arduion's PWM output, added a heatsink to the back of the LED, and grounded myself when handling the LED.
I can't figure out why this setup is failing to turn the LED on. I shouldn't need a resistor in line with a constant current power supply, right? I read 24V across the other input pads of the LED, so I know power is being delivered.
Am I burning it out somehow?
