A Constant Voltage LED Power Supply is a specialized power source designed to deliver a fixed output voltage (such as 12V or 24V) to LED lighting systems. Unlike constant current drivers, it maintains a stable voltage level while allowing the current to vary according to the load. This makes it ideal for LED strips, LED modules, light bars, and other applications where multiple LEDs are connected in parallel and require uniform voltage for safe and consistent operation.
The primary role of a Constant Voltage LED Power Supply is to ensure that LEDs receive a steady and reliable voltage, preventing flickering, premature failure, or uneven brightness. It acts as the backbone of modern LED lighting systems, especially in architectural, commercial, and decorative lighting projects.
Key functions include:
Voltage stabilization
Protection against overload and short circuits
Improving LED lifespan
Enhancing overall lighting performance
A Constant Voltage LED Power Supply converts AC mains electricity into a regulated DC voltage. Regardless of minor fluctuations in input voltage or load conditions, the output voltage remains constant. The LED load then determines how much current is drawn.
AC power input
Rectification and filtering
Voltage regulation
Stable DC voltage output
This structure ensures LEDs operate within their designed voltage range, improving safety and efficiency.
| Feature | Constant Voltage LED Power Supply | Constant Current LED Driver |
|---|---|---|
| Output Type | Fixed Voltage (e.g. 12V/24V) | Fixed Current (e.g. 350mA) |
| Current Control | Load-dependent | Regulated |
| Typical Applications | LED strips, modules | High-power LEDs |
| Wiring | Parallel | Series |
| Flexibility | High | Medium |
This comparison highlights why Constant Voltage LED Power Supply solutions are widely used in flexible and scalable lighting designs.
