Constant current (CC) TRIAC LED drivers are specialized power supplies that maintain a fixed, stable current (e.g., 350mA, 700mA) for LEDs while enabling dimming via standard trailing or leading-edge mains dimmers. They protect LEDs from current fluctuations, ensuring consistent brightness and longevity. These drivers are ideal for downlights, spotlights, and architectural lighting, often offering adjustable output currents and flicker-free performance.

Key Aspects of Constant Current TRIAC LED Drivers:

Functionality: Unlike constant voltage drivers, CC drivers vary the voltage to maintain a precise current, which prevents overheating and premature failure in high-power LEDs.

Dimming Technology: They work with traditional incandescent dimmers (TRIAC) to control brightness by chopping the AC phase.

Applications: Primarily used for high-power LED modules, spotlights, and COB (Chip on Board) lighting where a specific mA rating is required.

Safety & Efficiency: These drivers usually include built-in protections against short circuits, overloads, and overheating. They generally operate with high efficiency, often 75-80%.

Compatibility: Some advanced models feature multiple output current settings (e.g., 350mA to 700mA) selectable via DIP switches, making them versatile for different loads.

Common Ratings: Commonly available in power ranges from low wattages (3-7W) to higher power (30W-60W), suitable for various residential and commercial applications.

Dimming Issues: While they provide smooth dimming, some combinations of drivers and dimmer switches may cause flickering.
