LED soft light strip can use different power supply according to the model. What do you know about power supply? Do you know the different meanings of power supply type and LED light strip? Today we talk about the classification of LED soft lamps with power supply

There are different classification methods for light strip power supply according to different standards. In this paper, according to the classification of different driving modes, it can be divided into two kinds of voltage regulation and constant current. The following sections will describe in detail that there are two types of drives

1、 Regulated type

1. The voltage change caused by rectification will affect the brightness

2. Use voltage stabilizing drive circuit to drive LED, and add a suitable resistance to each string to make each string of LED display brightness average: c. The voltage stabilizing circuit is not afraid of open load, but it is strictly prohibited to completely short load;

3. When determining the parameters in the voltage regulator circuit, the output voltage is fixed, and the output current changes with the increase or decrease of the load

2、 Constant current

1. Pay attention to the maximum withstand current and voltage value used, which limits the number of LEDs used: b The constant current drive circuit is ideal to drive the LED, but the price is relatively high c The constant current circuit is not afraid of load short circuit, but it is prohibited to completely disconnect the load;

2. The current output of the constant current drive circuit is constant, and the output DC voltage varies within a certain range according to the load resistance. The load resistance is small, the output voltage is low, and the load resistance is large. The higher the output voltage.
