LED waterproof power supply can be divided into two categories according to driving mode

by:MOSO     2020-02-29
LED waterproof power supply is a kind of LED driving power supply, which is a voltage converter that converts power supply into specific voltage and current to drive LED to emit light. Usually: the input of LED driving power supply includes high voltage power frequency AC (That is, mains) , Low voltage DC, high voltage DC, low voltage high frequency AC (Such as the output of an electronic transformer)Wait. However, the output of LED driving power supply is mostly a constant current source that can change the voltage with the change of LED forward voltage drop value. LED waterproof power supply can be divided into two categories according to the driving mode :(1) Constant current type: a. The current output by the constant current drive circuit is constant, while the output DC voltage changes within a certain range with different load resistance values, and the load resistance value is small, the output voltage is low, and the greater the load resistance, the higher the output voltage; B, constant current circuit is not afraid of load short circuit, but it is strictly prohibited to load completely open circuit. C, constant current drive circuit is ideal to drive LED, but the price is relatively high. D, should pay attention to the use of * large withstand current and voltage value, it limits the number of LED use; (2) Voltage stabilizing type: a. When the parameters in the voltage stabilizing circuit are determined, the output voltage is fixed, while the output current changes with the increase or decrease of the load; B, voltage stabilizing circuit is not afraid of load open circuit, but it is strictly prohibited to load completely short circuit. C, drive LED with voltage stabilizing drive circuit, each string needs to add appropriate resistance to make each string of LED display brightness average; D, brightness will be affected by voltage changes from rectification.
