" Why constant current? - LED is the component that allows current through itself according to input voltage. In other words, it is close to voltage control component. General LED, especially Z-POWER LED must be driven by constant current. There are two main reasons. Firstly, LED is an optical device. How much luminous flux we can get from LED is very important. Generally luminous flux is closely related to driving current. It is easy to recognize and control optical characteristics by current constant. Secondly, LED is more sensitive to voltage than current."
