An LED driver is an essential component in an LED circuit that plays a vital role in controlling and managing the power supplied to an LED or a series of LEDs. Its primary function is to regulate the electrical current and voltage levels to ensure that the LEDs operate within their specified parameters.
Without an LED driver, several issues can arise, leading to potential system failure. An LED requires a specific amount of current to function optimally. Without a driver to regulate the current, the LED may receive excessive current, which can cause it to overheat, significantly reducing its lifespan or even causing immediate damage.
