LED drivers play a crucial role in ensuring that LED lights operate efficiently and effectively. Among the various types available, constant voltage LED drivers are particularly popular for their ability to provide stable output that matches the voltage requirements of many LED applications. This article will delve into the principles behind constant voltage LED drivers, how to choose the right model, and more.
定電圧LEDドライバとは？
定電圧 LED driver is a power supply designed to deliver a predetermined voltage with a built-in mechanism to ensure that the output voltage remains constant regardless of changes in load. This type of driver is ideal for applications where LED strips or arrays are connected in parallel and require a uniform distribution of voltage across all the components.
Principles of Constant Voltage Driving
The fundamental principle behind constant voltage driving is to maintain a steady voltage level (commonly 12V or 24V) across the load. This method is particularly beneficial as it allows for greater flexibility in LED circuit design. By ensuring a consistent voltage, the LED lights can operate at their optimal performance level, minimizing risks such as flickering or damage due to voltage fluctuations.

How to Choose a Model for Constant Voltage LED Driver
When selecting a constant voltage LED driver, keep the following factors in mind:
Input Voltage Specifications
Ensure that the driver’s input voltage aligns with your power source. Common input ranges for LED drivers include 100-240V AC.
出力電圧
Select a driver that provides the proper output voltage for your LED system. Common output voltages include 12V and 24V, which are widely used for various LED applications.
Power Rating
Choose a driver that can handle the total wattage required by your LED installations. The driver should be able to supply at least 20% more power than the total wattage of all connected LEDs to ensure efficiency and longevity.
Cooling Mechanisms
Opt for drivers with adequate cooling mechanisms, especially for high-wattage applications. Overheating can lead to driver failure and compromised LED performance.
Differences Between Constant Current and Constant Voltage Drivers
Understanding the difference between constant current and constant voltage drivers is also essential when selecting the appropriate power supply for your LED lights.
定電流ドライバー
Constant current drivers deliver a fixed amount of current while varying the voltage based on the load requirement. This setup is ideal when using high-power LED lights that need to maintain a specific current to avoid damage.
