Multi Chip White LED Modules

Description

The SEPW series of LEDs provides a range of high-powered

InGaN blue LEDs producing brilliant white light that can be

used in general lighting applications, amusement and gaming

equipment, and for backlighting TFT displays. Each module

combines 8 LEDs in 2 separate channels.

Modular design allows the SEPW devices to be easily assembled

into string arrays by simply connecting the modules in series.

The devices also provide superior color balance throughout

the display because of the high density of LEDs that can be

achieved. This also minimizes the distance that power and

control lines must run between LEDs and from the LEDs to

the control electronics.

The white thermoplastic case is an innovative Sanken original

design with exceptional heat dissipation properties. The white

resin compound is especially formulated for superior reflectance

and transmittance of the generated light. Enhanced thermal

dissipation is achieved through the incorporated heatsink on the

bottom of the package. The heatsink can be mated directly to an

external radiator through the PCB for superior heat conduction

allowing dense placement of modules.

The leadframe is plated with silver, providing a highly-reflective

surface for the bottom and sides of the emitting area. The

terminals and heatsink are also silver-plated.

The SEPW devices can be mounted in tight

arrays on a single PCB substrate for ease of

manufacture and to provide a dense, uniform

appearance when illuminated.

The application shown here uses eight

SEP8Wx2001 LED modules, each populated

by eight LEDs connected in series.
