LED soft light with power classification

The LED flexible strips can be used with different power supplies depending on the model. How much do you know about the power supply? Do you know the type of power required by the LED flexible strip and its different meanings? Today we will talk about the classification of LED soft light with power supply.

There are different classification methods for LED flexible lamp power supply according to different standards. This article mainly explains the classification according to the different driving methods, which can be made into two kinds of voltage regulator type and constant current type. The following will explain in detail. .

According to the driving mode can be divided into two categories 1.1 voltage regulator a, the brightness will be affected by the voltage change from the rectification;

b, to drive the LED with a constant voltage driver circuit, each string needs to be added with a suitable resistor in order to make each LED display brightness average;

c, the voltage regulator circuit is not afraid of load open circuit, but the load is strictly prohibited;

d, when the parameters of the voltage regulator circuit are determined, the output voltage is fixed, and the output current changes with the increase or decrease of the load;

1.2 constant current type a, should pay attention to the maximum current and voltage used, it limits the number of LED use;

b, constant current drive circuit to drive led is more ideal, but relatively high prices;

c, constant current circuit is not afraid of load short circuit, but the load is strictly prohibited open circuit;

d, the constant current drive circuit output current is constant, but the output of the DC voltage but with the size of the load resistance varies within a certain range, the load resistance is small, the output voltage is low, the greater the load resistance, the output The higher the voltage is.
