1W Power LED Light Source on MCPCB
Data Sheet
Description
1W 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 1W Power LED light source is mounted on to metal
core PCB enabling optimum heat dissipation and ease of
installation.
The low profile package design is suitable for a wide variety
of applications especially where height is a constraint.
Features
Available in Red, Amber, Green, Blue, Cool White and
Warm White color.
Energy efficient
High current operation.
Long operation life.
Wide viewing angle.
Silicone encapsulation
