Controllers are used for the precise current control (switching on and off) of LED lighting. Even small changes in voltage can increase the LED current and light emission so significantly that they can be destroyed in a very short time. It is therefore difficult to achieve precise lighting control via the power supply alone. A […]
Due to the diode characteristic of LEDs, even a small change in the supply voltage results in a large change in the diode current. In addition, the diode characteristic curve depends on the temperature of the LEDs. Therefore, an LED that is operated at too high a voltage without current limitation can quickly self-destruct(thermal runaway). […]
