Constant current (CC) LED drivers are specialized power supplies that deliver a fixed, stable current (e.g., 350mA, 700mA) while varying the output voltage to match the LED load’s requirements. Essential for high-power LEDs and series-wired circuits, they prevent thermal runaway, ensure consistent brightness, and extend LED lifespan.

Key Aspects of Constant Current LED Drivers:

Functionality: Unlike constant voltage drivers, CC drivers automatically adjust their voltage output within a specified range to keep the amperage constant.

Applications: Ideal for high-power LEDs, downlights, spotlights, and COB modules. They are crucial when LEDs are wired in series.

Benefits: Prevents, excessive current, which leads to premature burnout or “thermal runaway,” where heat causes the LED to draw more power, leading to failure.

Specifications: Usually rated by amperage (mA or A) and a voltage range (e.g., 700mA, 13~26V).

Dimming & Control: Many models support dimming methods like DALI, 1-10V, or TRIAC

Constant voltage (CV) LED drivers convert AC mains power to a stable, low-voltage DC (typically 12V or 24V) required for LED strip lights and modules. They are designed for parallel circuits where voltage must remain consistent to prevent flickering and ensure proper, long-lasting performance.

Key Aspects of Constant Voltage LED Drivers:

Applications: Primarily used for LED tape/strips, under-cabinet lighting, signage, and architectural lighting.

Voltage Output: Usually 12V DC or 24V DC.

Selection Criteria:

Voltage: Match the driver voltage to the LED strip voltage (e.g., 12V LED needs a 12V driver).

Wattage: Select a driver with a total wattage capacity higher (typically 20% over) than the total load of the LED strip.

Advantages: More cost-effective than constant current drivers, allowing for easy installation of multiple lights in parallel.

Dimming Options: Compatible with various dimming methods, including DALI, 0-10V, and TRIAC
