Application Of LED Driver

The application of LED driver depends on the LED parameters we want to drive. The two most important parameters are input voltage and input current. How to calculate the input voltage and current of LED lamp, here just say that the input of LED lamp is known. If you don't know, you can also choose to ask the LED product supplier, or look at the original driving parameters (Be sure to identify some driving virtual standard cases!)

After knowing the input voltage and input current of the lamp, we can select the corresponding LED driver to use. For example, in the following cases, if we know that the input voltage of the lamp is 37-40v and the input current is 300mA, we can select the LED driver whose output voltage includes it and the current is almost the same. In terms of matching, voltage higher or lower is not OK, it must be included. Otherwise, it will flicker. It doesn't matter if the current is lower.
