1W 3W LED Heatsink

The 1W–3W LED Heatsink (20mm Aluminum Base Plate) is a high-efficiency thermal management component designed for single high-power LED chips. It is built from anodized aluminum, which enhances heat dissipation and improves durability against corrosion and wear.

This heatsink is specifically designed to maintain optimal operating temperatures for 1W, 3W, and 5W LED chips, ensuring stable brightness and extended lifespan. Its compact 20mm star-shaped PCB base allows easy mounting of LED chips while providing direct thermal conduction.

The low thermal resistance design ensures rapid heat transfer away from the LED junction, preventing overheating and performance degradation in lighting systems.
