« Dois-je utiliser un constant voltage led power supply or a constant current led power supply to drive my LED strips?"As a pioneer in providing reliable and high quality LED drivers, Smarts Electronics has been asked questions like this many times. Unfortunately, there is no simple answer to this question. There are different approaches to consider depending on the stage of the design cycle of the LED application and the structure of the LED strips in use.

1 ） Advantages of using the constant voltage topology:

A more familiar technology for the design engineers and installation technicians The cost can sometimes be lower.

2 ） Advantages of using the constant current topology:

Avoids violating the absolute Max. forward current specified for the LEDs and compromising the reliability Achieves more consistent brightness between different LED strips.
