The Development Trend of LED Power Drivers
The development trend of LED power supply driver - LED power supply driver is a voltage converter that converts the power supply into a specific voltage and current to drive LED lighting. In recent years, with the development of LED, the development trend of LED power drivers has become particularly evident. Today, I will briefly explain the development trend of LED power drivers to you.
Firstly, a series of constant voltage and current control electronic circuits are developed based on the characteristics of LEDs. Integrated circuit technology is used to control the input current of each LED at the optimal current value, enabling the LED to obtain stable current and generate the highest output luminous flux. It is best to control the size of the LED current when the input voltage and environmental temperature of the LED driver power supply change. (Related knowledge: Classification of LED backlight sources)
Secondly, the LED driver power supply has an intelligent control function, allowing the load current of the LED to be controlled at a predetermined level under the influence of various factors. When the load current changes due to various factors, the primary control IC can control the switch to return the load current to the initial design value.
The development trend of LED power drivers - in terms of control circuit design, it is necessary to develop towards centralized control, standard modularization, and system scalability.
