As the LED application is becoming more and more widely, the performance of the LED drive power supply will be more and more suitable for the requirements of the LED.
The led driver power supply drive mode:
Popular now have two kinds: one is a constant voltage source for multiple constant current source, each constant-current source separate for each LED power supply. This way, flexible combination, LED failure all the way, don't affect the work of other leds, but the cost would be slightly higher. The other is a constant current power supply directly, leds in series or parallel operation. It has the advantage of low cost, but poor flexibility, but also solve a LED failure, does not affect other LED running problem. These two forms, for a period of time. Multi-channel constant current output power supply way, in terms of cost and performance will be better.
Led drive power supply input, including high voltage ac power frequency (mains), low-voltage dc, high-voltage direct current, low voltage high frequency ac (such as the output of electronic transformer). And the output of the LED driver power supply are mostly can change with LED positive pressure drop values and change the voltage of the constant current source.
