Moonstone® 1W Power LED Light Source
Data Sheet
Description
The Moonstone® 1W Power LED Light Source is a high per-
formance energy efficient device which can handle high
thermal and high driving current. The exposed pad design
has excellent heat transfer from the package to the moth-
erboard.
The low profile package design is suitable for a wide variety
of applications especially where height is a constraint.
The package is compatible with reflow soldering. This
will give more freedom and flexibility to the light source
designer.
The 1W Power LED light source can be mounted onto
metal core PCB enabling optimum heat dissipation and
ease of installation.
