Heatsinks are low cost and
easy assembly heat sinks for
“Star” LED packages supplied
by Cree, Lumileds, Osram and
others. This simple heat sink
can hold LED modules and
can be mounted simply with
some thread forming screws.
The heat sink has two types
of surface finish and can be
used in either natural (free)
or forced convection cooling
applications.
