Additional Information

An LED driver is a power conversion device specifically designed to drive LED light sources. Its essential characteristic is constant current output, providing a steady current to ensure uniform brightness and operational lifespan of the LEDs. Meanwhile, the market also includes constant voltage output products, which are used to适配 LED light strips, signage modules, and other loads that have built-in current-limiting circuits or resistors. Depending on application requirements, driver types include constant power models, dimmable types (supporting 0-10V, PWM, DALI, or triac dimming), and those with IP65 (or other) ingress protection ratings. When selecting a driver, key considerations include matching the voltage-current characteristics of the LED load, power factor (>0.9), output ripple current suppression capability, and surge protection level.
