    For high-power LED systems, overheating is the #1 threat to performance and lifespan. Our Round Sunflower Aluminum Heatsink delivers industry-leading passive cooling to keep your LED modules running reliably—even under heavy loads.

    Key Advantages: Designed for Optimal Thermal Management

    1. High-Conductivity Aluminum Construction

    Crafted from 6063-T5 aluminum alloy (thermal conductivity: 201 W/m·K), this heatsink balances lightweight design (30% lighter than copper alternatives) with rapid heat transfer. Anodized surface treatment adds corrosion resistance, ensuring durability in indoor/outdoor applications.

    2. Sunflower Fin Geometry: Maximize Heat Dissipation Area

    The radial "sunflower" fin design expands surface area by 400%+ compared to flat heatsinks. Dense, precisely extruded fins (20+ fins per unit) accelerate natural convection, reducing LED chip temperatures by up to 15°C (tested with 30W LED modules).

    3. Passive Cooling: Silent & Low-Maintenance

    No fans or moving parts—rely on natural airflow for quiet, energy-free operation. Ideal for applications where noise or maintenance downtime is a concern (e.g., streetlights, industrial lighting, high-bay fixtures).

    4. Customizable Specifications

    We offer tailored dimensions (diameter: 80–150mm; height: 30–80mm) to match your LED power (12W–50W) and installation space. Optional mounting holes or thermal adhesive compatibility simplify integration.

    Performance Validation

    In thermal simulations (SolidWorks Flow Simulation) and real-world tests:
    • A 30W LED module paired with our 115mm-diameter heatsink maintained a chip temperature of 52°C (ambient 25°C)—well below the 125°C safety threshold.
    • Lifespan of LED modules increased by 60% compared to systems using basic heatsinks.

    Who Benefits?

    • LED lighting manufacturers (streetlights, high-bay lamps, floodlights)
    • Industrial electronics designers (power supplies, semiconductors)
    • DIY engineers building high-power LED prototypes
    We prioritize quality and scalability: our extrusion process ensures consistent thermal performance across 100+ unit batches.
