What is the basic working principle of LED linear lighting power supply?

1. What is LED

LED is a light-emitting diode, a semiconductor element that converts electrical energy into light energy. Its basic structure is an electroluminescent semiconductor chip placed on a lead frame and sealed with epoxy resin. LED is highly efficient and has relatively low energy consumption. With the development of the times, it gradually replaces traditional light sources.

2. Linear lighting power supply

Speaking of linear lighting power supply, many people may not know much about it. Simply put, the voltage regulation of linear lighting power supply can be regarded as the resistance adjustment value, which is equivalent to changing the voltage by adjusting the sliding rheostat, while the switching power supply changes the voltage by adjusting the switching frequency. So what is the basic working principle of linear lighting power supply? The following is a detailed introduction for everyone.

3. The basic working principle of LED linear lighting power supply

The voltage feedback circuit of LED linear lighting power supply works in the amplification state, and the switching power supply refers to the tube used for voltage adjustment working in the saturation and cutoff area, which is what we call the switching state.

The linear lighting power supply samples the output voltage and then sends it to the comparison voltage amplifier together with the voltage. The output of the voltage amplifier is used as the input of the voltage adjustment tube, thereby controlling the adjustment tube so that its voltage begins to change with the input and adjusts its output voltage. However, the switching power supply changes the output voltage by changing the switching time and proportion of its adjustment tube.

When we use the form of resistor voltage division to achieve stable output, we can call this process LED linear lighting power supply.

LED linear lighting power supply can be used in many places. If you have other questions, please feel free to consult Guangzhou Yuxiang Electronic Technology Co., Ltd.!
