Introduction to the basic knowledge of LED lighting power supply

(1) Constant current: The output current of the constant current drive circuit is constant, but the output DC voltage varies within a certain range with the load resistance. The smaller the load resistance value, the lower the output voltage; the larger the load resistance value, the higher the output voltage; the constant current circuit is not afraid of the load short circuit, but it is strictly forbidden to completely open the load; the constant current drive circuit is ideal for driving LEDs, but relatively The price is higher; attention should be paid to the maximum withstand current and voltage used, which limits the number of solar street lights used. (2) Voltage-stabilizing type: When the parameters in the voltage-stabilizing circuit are determined, the output voltage is fixed, but the output current changes with the increase or decrease of the load; the voltage-stabilizing circuit is not afraid of the load being open, but the load is strictly prohibited. Complete short circuit; drive the LED with a regulated drive circuit, and each string needs to be added with a suitable resistor to make each string of LEDs display even brightness; the brightness will be affected by the rectified voltage change.

solar lights are among the best and the long known , which plays an essential part in automatic manufacturing.
