LED Drivers are specialized power supplies designed to regulate the power required for LED (light emitting diode) lighting systems. These devices ensure that the LED receives the correct voltage and current necessary to function efficiently. The main functions of LED drivers are to convert higher voltage, alternating current to low voltage, direct current, and to keep the voltage and current flowing through an LED circuit at its rated level. This is crucial as too high a current can overheat and damage the LEDs, while too low a current can result in inadequate light output.
The primary uses of LED drivers are in various lighting applications where LEDs are used, such as residential lighting, commercial lighting, street lighting, and decorative lighting. Characteristics of these products include dimming capabilities, high energy efficiency, and a long lifespan which reduces maintenance costs. They often come with protective features against overvoltage, overcurrent, and overheating, ensuring the safety and durability of LED systems. Notable manufacturers of LED drivers include Mean Well, Philips Advance, and Inventronics.
