STAR Heat Sinks Cool High Heat-Flux LEDs

Advanced Thermal Solutions STAR LED heat sinks are designed for cooling high heat-flux LEDs.

ATS' STAR heat sinks offer superior thermal performance. Cooling performance reaches more than 60 K (T_HS-ambient) at 50.0 W of power dissipation, depending on model.

The STAR heat sinks are made from lightweight aluminum in a round profile that fits common LED applications. Cooling fins are arrayed in a round, star-like cross section that optimizes thermal performance in local air flow. The STAR heat sinks are available with or without base plates. A flat base at one end allows secure, direct-mounting of LEDs. Integral threads on the base perimeter allow attachment of brackets and other hardware. An inner thread allows the convenient attachment of LED lens mounts.

Standard STAR heat sinks are available in lengths from 18 mm to 85 mm. ATS also offers STAR extrusion profiles for custom lengths up to 1,000 mm. The STAR heat sinks are offered in diameters of 45 mm, 60 mm and 80 mm. The heat sinks feature a black anodized finish or black anodized finish with a silver tip that provides corrosion resistance, electrical insulation, and improved thermal performance. All heat sinks within the series are RoHS compliant.
