LED power supplies come in many varieties, and there are significant differences in quality and price among them. This is one of the key factors influencing both product quality and pricing. LED power supplies can be categorized into two main types based on their driving methods: 1. Constant-Current Type ① Constant-current driver circuits are ideal for driving LEDs. ② Although constant-current circuits are not afraid of short circuits in the load, they must never be allowed to have a completely open circuit. ③ The output current of a constant-current driver circuit remains constant, while the output DC voltage varies within a certain range depending on the magnitude of the load resistance. ④ The number of LEDs that can be used must be limited, as each LED has maximum allowable current and voltage ratings. 2. Voltage-Stabilized Type ① After the parameters of the voltage-stabilized circuit have been set, it outputs a fixed voltage; however, the output current will change according to the increase or decrease in the load. ② Although voltage-stabilized circuits are not afraid of open-circuit loads, they must never be allowed to have a complete short circuit. ③ Voltage fluctuations after rectification can affect the brightness of the LEDs. ④ To ensure uniform brightness when driving LEDs with a voltage-stabilized circuit, appropriate resistors must be added.

LED power supply There are many different types, and the quality and price of various power supplies vary significantly. This is also one of the key factors influencing product quality and pricing.
LED power supplies can be divided into two major categories based on their driving methods:
1: Constant Current Type
①. A constant-current driving circuit is ideal for driving LEDs.
② Although a constant-current circuit is not afraid of short circuits in the load, it is strictly forbidden for the load to be completely open-circuited.
③ The current output by the constant-current drive circuit is constant, while the output DC voltage varies within a certain range depending on the magnitude of the load resistance.
4. The number of LEDs used should be limited, as each LED has a maximum allowable current and voltage rating.
Two: Voltage-regulated
① After the parameters of the voltage-regulating circuit have been determined, the output is a fixed voltage, but the output current varies depending on whether the load increases or decreases.
② Although the voltage-regulating circuit is not afraid of an open-circuit load, it is strictly forbidden to allow the load to become completely short-circuited.
③ The voltage variation after rectification will affect the brightness of the LED.
④ To ensure uniform brightness in each string of LEDs driven by a voltage-regulating circuit, it is necessary to add appropriate resistors.
