The drive is like the blood of a tube lamp, maintaining the stable operation of the entire interior of the lamp and extending its service life to a certain extent. The common constant current drive can prevent the driving current from exceeding the maximum rated value, thereby ensuring that the LED lamp meets the expected brightness and color temperature requirements. The stable constant current input and output can more effectively extend the service life of the lamp.
Especially when lighting fixtures need to be dimmed, it is difficult to maintain consistency in lighting brightness. A small increase in voltage can lead to an exponential increase in current, and if adjusted improperly, it can sometimes damage LED lighting fixtures. In addition, constant current circuits are also less prone to bias caused by the internal or external heat generated by the components themselves, resulting in a decrease in forward resistance (reducing voltage difference) and a thermal runaway phenomenon of an increase in current passing through the device. This improves the reliability of LED lamps in long-term operation.
