Each of the 32 Star LED heat sinks, which are RoHS compliant and designed for convection cooling of high-heat-flux LEDs, provides enhanced heat transfer for effective LED cooling without fans or blowers. Cooling performance reaches more than 60 K (& #916;Ths-ambient) at 50 W of power dissipation. Constructed of lightweight aluminum in a round profile that fits common LED applications, they are available in lengths from 0.98 to 39.37” (25 to 1,000 mm) with a standard diameter of 1.77” (45 mm).
Cooling fins are arrayed in a round, star-like cross section that optimizes thermal performance in local airflow. A flat base at one end allows direct mounting of LEDs. Each heat sink has a black anodized finish that provides corrosion resistance, electrical insulation and improved thermal performance.
