Constant Current (CC) LED drivers provide a fixed, regulated current (measured in mA or A) to LEDs, varying the voltage as needed to maintain optimal brightness and prevent thermal runaway. They are essential for high-power LEDs, COB modules, and series-wired, ensuring consistent performance and preventing premature failure.

Key Aspects of Constant Current LED Drivers:

Functionality: Unlike constant voltage (CV) drivers, CC drivers change the output voltage automatically to keep the current stable.

Wiring: These drivers require LEDs to be connected in a series circuit, where the same current flows through each LED.

Applications: Ideal for single high-power LEDs, LED downlights, COB modules, and specialized fixtures (e.g., 350mA or 700mA).

Pros: They offer high efficiency, consistent brightness, and prevent LEDs from drawing too much power (thermal runaway).

Selection: When purchasing, you must match the driver’s output current (mA) and voltage range to the specific requirements of the LED fixture.

Dimming: Many CC drivers support dimming protocols such as DALI, 1-10V, Bluetooth, or TRIAC.

Constant voltage (CV) LED drivers convert high-voltage AC mains into a stable, fixed low-voltage DC (typically 12V or 24V). They are primarily used for LED strips, tape lights, and modules connected in parallel. These drivers ensure consistent brightness across installations by maintaining a steady voltage, even if the total load changes.

Key Aspects of Constant Voltage LED Drivers:

Applications: Ideal for LED strips, linear lighting, under-cabinet lighting, and signage that have built-in current-limiting resistors.

Common Outputs: 12V DC and 24V DC are the most standard, though 36V and 48V exist for specific applications.

Key Specifications: When selecting, it is crucial to match the output voltage (e.g., 12V) and ensure the driver wattage exceeds the total power consumption of the LED strip.

Dimming: Many CV drivers support dimming protocols such as DALI, 1-10V/0-10V, Bluetooth, and TRIAC/phase-cut dimming.

Safety & Design: They protect LEDs from voltage fluctuations and are available in various IP ratings (e.g., IP20 for indoors, IP67 for outdoors).

Wiring: Devices are wired in parallel, allowing for easy installation of, or cutting to, different lengths of LED tape.
