The main functions of the LED drive circuit are to transfer the AC voltage into a constant power supply and match the voltage and current according to the requirements of LED devices. Apart from safety need, the LED driver circuit must also include two other basic features:
First, a constant current should be kept as long as it is possible, thus the output current variation is able to be maintained between the range of ±10％ especially when the power supply change goes beyond ±15％range. Here are the reasons for having a constant current driver when using LED as the monitor, other lighting devices or backlighting: 1.To prevent the drive current from exceeding the maximum rate and further affecting its reliability. 2.To meet expected brilliance requirements and ensure the color and brilliance homogeneity of each LED. Second, the driver circuit should keep low power consumption so that the LED system efficiency can remain at a high level. |
