When it comes to LED lighting, the type of driver you choose can significantly affect performance, efficiency, and longevity. Among the popular choices, constant voltage and constant current drivers stand out. This article explores the differences between these two types, helping you make an informed decision for your lighting projects.
Mitä ovat LED-ohjaimet?
LED-ajurit are essential components in LED lighting systems. They provide the necessary power and regulate the voltage or current to ensure optimal performance. A driver’s main goal is to convert the input power from your electrical supply into a form that your LED lights can use effectively.
Constant Voltage vs. Constant Current: The Basics
Vakiojänniteohjaimet
Constant voltage drivers maintain a consistent output voltage, typically 12V or 24V, irrespective of the load connected. These drivers work best in applications where the LED fixtures are designed to operate within a fixed voltage range. They allow for more flexibility in wiring setups, as multiple LED lights can be connected in parallel without overloading the driver.
Vakiovirta-ajurit
In contrast, constant current drivers deliver a fixed current to the LED load. They automatically adjust the voltage as needed to maintain that current level. This type of driver is ideal for applications where a specific current is required to achieve the desired brightness, ensuring that all lights operate uniformly.

Applications Suited for Constant Voltage
Constant voltage drivers are commonly used in LED strip lighting, architectural lighting, and various decorative lighting setups. If your installation requires linking several LED modules, constant voltage drivers are typically the go-to choice. They allow you to create longer runs without worrying about uneven brightness or power drop across the length of the installation.
Wiring Constant Voltage LED Drivers
When wiring a constant voltage LED driver, it’s crucial to follow manufacturer specifications to ensure safety and efficiency. These drivers can generally handle a variety of LED loads as long as the total current does not exceed the driver’s rating.

Applications Suited for Constant Current
Constant current drivers are preferred in applications where precise brightness control is necessary, such as in high-output LED fixtures. They are particularly beneficial in street lighting, automotive headlights, and other high-demand scenarios where a consistent light output is essential for performance and safety.
Wiring Constant Current LED Drivers
Wiring a constant current LED driver requires careful consideration of the load. Each LED fixture must be rated for the driver’s output current; connecting fixtures with different ratings can lead to inefficient performance or damage.
