Heatsinks for high-power LEDs

19 November 2014 Circuit & System Protection

Advanced Thermal Solutions has added to its series of Star LED heatsinks designed for convection cooling of LEDs with high heat flux. Each of the 32 heatsinks provides enhanced heat transfer for effective LED cooling without fans or blowers.

Cooling performance reaches more than 60 K (ΔThs-ambient) at 50 W of power dissipation, depending on the model.

The heatsinks are made from lightweight aluminium in a round profile that fits common LED applications. Cooling fins are arrayed in a round, star-like cross section that optimises 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 heatsinks are available in lengths from 25 to 1000 mm and a standard diameter of 45 mm. Each model features a black anodised finish that provides corrosion resistance, electrical insulation and improved thermal performance. All parts within the series are RoHS compliant.
