High-Performance STAR LED Heat Sinks

Advanced Thermal Solutions (ATS) High-Performance STAR LED Heat Sinks provide high-performance convection cooling and a base heat sink platform for engineers to create custom LED thermal solutions. An LED's performance is temperature-sensitive, as higher temperatures cause degradation in life and light emittance. ATS High-Performance STAR LED Heat Sinks help prevent that issue by offering aluminum heat sink extrusions designed for high heat flux round or star-shaped LED elements. The heat sink material is lightweight anodized aluminum for maximum thermal performance.
