MoonstoneTM 3W Power LED Light Source

Data Sheet

Description

The Moonstone™ 3W Power LED Light Source is a high
performance energy ecient 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 prole package design is suitable for a wide variety
of applications especially where height is a constraint.

The package is compatible with reow soldering. This
will give more freedom and exibility to the light source
designer.
