LED Driver Explained
What Is an LED Driver?
An LED driver (also known as an LED converter or LED power supply) is an electronic component that converts the mains voltage (230 V alternating current) into the low voltage and/or constant current required by LEDs. LEDs cannot be operated directly from the mains voltage – the driver protects the LED from overvoltage and ensures stable, flicker-free operation.
Which Types of LED Driver Are Available?
- Constant-Current Driver (CC): Delivers a fixed current (e.g. 350 mA, 700 mA) at variable voltage. Standard for high-power LEDs in recessed luminaires and spotlights.
- Constant-Voltage Driver (CV): Delivers a fixed voltage (e.g. 12 V or 24 V) at variable current. Typical for LED strips and LED modules.
Why Does Driver Quality Matter?
The LED driver significantly influences the light quality, lifespan and dimming behaviour of an LED luminaire. A low-quality driver can lead to flicker, humming, a shortened lifespan and poor dimming performance.
Frequently Asked Questions (FAQ)
Is the driver integrated into the luminaire?
In many LED luminaires, yes. Some systems – particularly recessed luminaires and track systems – use external drivers that are mounted separately.
Can I replace a defective LED driver?
For luminaires with an external driver, replacement is generally possible. For luminaires with an integrated driver, it is advisable to contact the manufacturer.
In Summary:
The LED driver is the heart of every LED luminaire. Its quality determines light quality, dimming behaviour and lifespan. At Leuchtenland.com you will find suitable drivers and control gear for various LED systems.
