When it comes to powering LED lights, understanding the difference between constant voltage (CV) and constant current (CC) drivers is crucial for selecting the right equipment for your lighting needs. This article will break down the fundamental concepts, advantages, and applications of each driver type, equipping you with the knowledge to make informed decisions.
Mitä ovat LED-ohjaimet?
LED drivers are essential components in LED lighting systems. They serve the purpose of regulating the power delivered to the LED lights, ensuring optimal performance and longevity. Depending on the design and requirements of the LED fixture, you may need a constant voltage or a constant current driver.

A constant voltage LED driver maintains a fixed output voltage, typically at 12V, 24V, or 36V. This means that the driver provides a steady voltage level regardless of the LED load. This driver is commonly used for LED strips and light bulbs that are compatible with a specific voltage.

In contrast to constant voltage drivers, constant current LED-ajurit supply a fixed current to the LED fixture, adjusting voltage output as necessary to maintain that current. This is essential for LED lights that can have varying resistance and require a consistent current for optimal performance.

The primary distinction between constant voltage and constant current drivers boils down to what they regulate. Constant voltage drivers maintain a steady output voltage, while constant current drivers focus on delivering a specific current level.
Impact on LED Performance
LEDs powered by constant current drivers are generally more reliable and have better color consistency, since the current supplied remains stable. Constant voltage drivers may lead to variations in brightness if the load changes and can cause overheating if not properly managed.
Wiring Configurations
Constant voltage systems often allow for simpler wiring configurations, mainly based on parallel connections. Constant current systems may require more complex connections, as LEDs are typically wired in series to ensure the proper current flow.

When deciding between constant voltage and constant current LED drivers, it’s crucial to consider the specifications of the LED lighting you plan to use, as well as the overall application. For flexible installations and devices requiring a fixed voltage, constant voltage drivers are ideal. However, for high-performance LEDs and consistent operation, constant current drivers provide superior efficiency.
As with any lighting installation, consulting with a professional can help you choose the right driver that meets your lighting design’s requirements, ensuring optimal performance for years to come.
