LED driver and LED power supplies

LED driver and LED power supplies

LED drivers are electronic circuits or modules that limit the current flow through a LED. In this case, the illuminant per se has no current limiters. In contrast, LED voltage is controlled by a power supply. The corresponding lamp should be fitted with a current limiter. It converts AC to DC power required for LED operation. A constant current –e.g. 350 mA at 1 W LED– is especially important for LED powering because otherwise they do not reach their maximum brightness, or may even be destroyed.
