LED technology has become a staple in modern lighting due to its energy efficiency and long lifespan. A critical component that affects LED performance is the driver, which determines the mode of electrical supply. The two primary types of LED drivers are constant voltage and constant current, each with distinct characteristics that make them suitable for different applications. This article examines the differences, advantages, and considerations for choosing between constant voltage and constant current LED 驱动器.
什么是恒压 LED 驱动器?
恒定电压 发光二极管 driver is designed to supply a fixed output voltage to the LED circuit. These drivers are ideal for LED systems where the voltage requirement is consistent across all components.
恒压 LED 驱动器的特性
恒压驱动器通常提供 12V 或 24V 输出,适用于多个 LED 并联的应用。它们简化了布线和安装过程,因为每个 LED 灯串只需共享一个公共电压。
