LED (Light Emitting Diode) technology has rapidly gained popularity, particularly in lighting applications. One of the critical aspects of LED systems is the power supply, specifically the constant voltage LED driver. This article delves into the essential features, workings, and the relevance of constant voltage LED drivers in various applications.
Mikä on vakiojännite-LED-ohjain?
Määritelmä ja toiminta
Vakiojännite LED driver is a power supply unit that regulates the voltage supplied to LED lights. Unlike constant current drivers, which adjust the current according to the load, constant voltage drivers maintain a fixed output voltage. Common specifications include 12V, 24V, or 36V, with 12V being the most prevalent in residential applications.
Why Use Constant Voltage?
Constant voltage LED-ajurit are favored for their simplicity and compatibility with standard voltage LED fixtures. These drivers ensure the LEDs receive a consistent and stable voltage, which helps prevent fluctuations that could lead to flickering or reduced lifespan.
Key Features of Constant Voltage LED Drivers
