Before we dive into the specifics, it’s essential to understand what an LED<\/a> driver is. An LED driver is an electrical device that regulates the power supplied to LED lights. LEDs require specific voltage and current levels to operate efficiently, and without a suitable driver, they can underperform or go through premature failure. Essentially, the driver acts as a bridge between the power source and the LED, ensuring that the required electrical specifications are met.<\/p>\n

In contrast to constant voltage drivers, constant current LED \ub4dc\ub77c\uc774\ubc84<\/a> provide a consistent output current while the voltage may fluctuate depending on the load. This means that circuit designs must account for the amount of current each LED requires to function properly, which can differ among LED fixtures.<\/p>\n
