Constant Current vs Constant Voltage Dimmable LED Drivers

WebLEDs are driven "constant-current" because they are not linear; they have a very steep voltage-current curve that is influenced by age and temperature. (hotter = higher current at same voltage, causing a thermal runaway situation). Constant-current is … WebApr 26, 2024 · Constant Current Reduction (CCR) Dimmers CCR dimmers work by controlling the amount of current flowing through the LED. The light produced is proportional to the amount of current flowing through the LED, so if a light is dimmed to 25%, only 25% of the rated LED current is provided.
