Mean Well is one of the leading switching power supply providers in the world, which includes LED drivers for a wide range of lighting applications. Best match. The constant current supply tries to compensate for the lack of current when the led is dimming. When I wrote this I didn't see that OP had edited in his driver already. LED Optics Optics control the illumination pattern, either diffusing it or focusing it as your application requires.

    Constant current LED drivers are designed for a designated range of output voltages and a fixed output current mA. The difficulty you have is that the CC driver is itself an SMPS power supply with it's own switching frequency, voltage control and current control.

    There will be a tiny power savings because it will lower Vf slightly due to less current going through LED.

    Constant voltage drivers are designed for a single direct current DC output voltage. LEDs that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps mA or amps A. Living in the beautiful state of Vermont and working for a company like LEDSupply that is helping provide LED products to save on energy is a great place to be in accomplishing this.

    Yes you CAN PWM a CC module that does not support dimming natively. The difficulty you have is that the CC driver is itself an SMPS power. › product-c › Dimmable-Constant-Current-LED.
    The excess forward current would result in extra heat within the system, cut down on the LEDs lifespan, and eventually ruin the LED. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Viewed times.
