Star Heat Sinks Cool High Power LEDs

Advanced Thermal Solutions, Inc. (ATS) has added a series of Star LED heat sinks designed for convection cooling of high heat flux LEDs to its portfolio. 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.

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. 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.

ATS Star heat sinks are available in lengths from 25 to 1,000 mm (0.98 to 39.37 in). Standard diameter 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.

ATS provides more LED cooling information on its website, Qats.com, including a comprehensive LED Cooling Resource Kit. The free kit includes downloadable technical resource materials for engineers responsible for the proper performance of LED designs. Contributors include Arrow Electronics and globally-recognized thermal management experts.
