3W Power LED Light Source
Data Sheet
Description
The Moonstone™ 3W Power LED Light Source is a high
performance 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
motherboard.
The Cool White Power LED is available in various color
temperature ranging from 4000K to 10000K and Warm
White Power LED ranging from 2600K to 4000K.
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.
