Cooling made easy with Star LED heat sinks

20th November 2013
Staff Reporter

The series of Star LED heat sinks has been expanded by Advanced Thermal Solutions. Designed for convection cooling of high heat flux LEDs, each of the 32 heat sinks provides enhanced heat transfer for effective LED cooling without fans or blowers. Cooling performance reaches more than 60 K (∆Ths-ambient) at 50.0 W of power dissipation, depending on model.

Made from lightweight aluminum in a round profile, the Star heat sinks fit common LED applications. Cooling fins are arrayed in a round, star-like cross section that optimizes thermal performance in local air flow. 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 on most models allows convenient attachment of LED lens mounts.

Available in lengths from 25 to 1,000 mm (0.98 to 39.37 in), the standard diameter of the Star Series is 45 mm (1.77 in). Each heat sink features a black anodized finish that provides corrosion resistance, electrical insulation, and improved thermal performance. All heat sinks within the series are RoHS compliant. Unit pricing for Star Series LED cooling solutions start at less than $6.00 in production quantities. They can be ordered on the ATS website – Qats.com or at 1-781-769-2800.
