LED constant voltage drivers are crucial components in modern lighting systems, enabling the effective functioning of LED lights while ensuring reliability and energy efficiency. In this article, we will explore what LED constant voltage drivers are, how they differ from constant current drivers, their applications, and key factors to consider when selecting them.
Что такое светодиодный драйвер постоянного напряжения?
An LED constant voltage driver is a power supply designed to maintain a constant output voltage regardless of changes in the load or input voltage. This type of driver ensures that LED lights receive a stable voltage level, which is critical for their optimal performance. Typically, constant voltage drivers are rated in volts and are compatible with various LED systems, including strips, bulbs, and fixtures.
The Functionality of Constant Voltage Drivers
The primary function of a constant voltage driver is to convert the alternating current (AC) from the power source into a direct current (DC) that LEDs require. Additionally, they regulate the output voltage to prevent fluctuations that might affect the brightness and lifespan of the LED lights. Common output voltages for these drivers include 12V, 24V, and sometimes 36V, depending on the application.
