The LED driver is an electrical device that regulates power to a string of LEDs. The electrical properties change with temperature and regulation of power is necessary to get an constant output power. LEDs have the risk of failure as it can become too hot and unstable if not properly driven.1 watt LEDs has the advantage of small size and point brightness and low power requirement. 1 watt LEDs are driven by capacitive power supply circuit. The capacitor forms the current limiter so that voltage supplied to LED never exceeds the safe limit.
