在为 LED 灯供电时,主要有两种 LED 驱动器:恒压和恒流。了解这两种驱动器之间的区别,有助于您在选择 LED 照明解决方案时做出明智的决定。在本文中,我们将探讨什么是恒压和恒流驱动器、它们的应用、优缺点,以及如何根据自己的需要选择正确的选项。
什么是恒定电压?
Constant voltage drivers deliver a fixed output voltage to the 发光二极管 lighting system. This means that the driver provides a steady voltage level, regardless of variations in load current. It is typically used in applications where the LED lights operated are rated for a specific voltage, such as 12V or 24V.
恒压驱动器的应用
恒压驱动器是 LED 灯条、某些 LED 灯泡和其他需要统一电压的照明应用的理想选择。它们通常用于需要在长距离 LED 灯条上提供一致照明的住宅和商业照明解决方案中。
什么是恒定电流?
另一方面,恒流驱动器可提供固定的输出电流,而不受输出电压变化的影响。这种驱动器旨在以最佳电流驱动 LED 光源,确保亮度一致,避免过流损坏。输出电压可以随着负载的变化而变化,以保持恒定的电流输出。
恒流驱动器的应用
恒流驱动器适用于需要精确亮度控制的大功率 LED 或灯具。它们通常用于专业照明应用,如舞台照明、建筑照明和街道照明,在这些应用中,保持亮度水平至关重要。
