Hello.
I have a high-power LED light armature, the light is dimmable from about 150W to 280W, but the 160W is still to bright.
I am using a constant-current LED power supply from Mean Well(which feature an adjustable output current, hence the dimmable light) and I was thinking of simply using a PWM controller and a half-bridge(or simply a high- or low-side switch) to PWM dim the output of that constant-current switching power supply.
But I don't know if it's a good idea to PWM the output of a constant-current switching power supply.
Is that a problem or should the LED power supply be able to manage such a load?
Regards
