Shwo F Series

爍(F)
Shwo(F)
1W Series
“Shwo(F) [Shuo(F)] is the English translation for the Chinese word meaning Twinkle and
is often used as a description of stars or other bright, celestial objects as seen from
Earth. This word is a relevant description for this bright, compact Everlight LED
package.”
Introduction
The Shwo(F) series is a surface-mount high-power device
featuring high brightness combined with a compact size that is
suitable for all kinds of lighting applications such as general
illumination, flash, spot, signal, industrial and commercial
lighting. The Shwo(F) series is one of the most promising
devices in Everlight’s high power product offering and is ready
to face the challenges of today’s Solid-State Lighting requirements.

Storage Conditions

Recommended to operate in accordance with the following conditions, increased LED life.

Before the package is opened. The LEDs should be stored at 30°C or less and 85%RH or less
after being shipped from Everlight and the storage life limits are 1 year. The LEDs can be stored
up to 3 years If in a sealed container with a nitrogen atmosphere and moisture absorbent
material.

After opening the package: The LED's floor life is 1 year under 30℃ or less and 60%RH or less.
The LED should be soldered with 168hrs (7days) after opening the package. If unused LEDs
remain, it should be stored in moisture proof packages.

If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the
storage time, baking treatment should be performed using the following conditions. Baking
treatment: 60±5℃ for 24 hours.
Thermal Management

Recommended to operate in accordance with the following conditions, increased LED life.

For maintaining the high flux output and achieving maximum reliability, EHP-C19 flashlight
series LEDs should be mounted on a metal core printed circuit board (MCPCB) or other kinds of
heat sink with proper thermal connection to dissipate approximately 1W of thermal energy at
350mA operation.

Sufficient thermal management must be implemented. Please refer to the graph “Forward
Current Derating Curve“ on Page 20. The soldering temperature must be kept under 60℃ at the
driving current 350mA.Otherwise, the junction temperature of die may exceed over the limit at
high current driving conditions and the LEDs’ lifetime may be decrease dramatically.

Special thermal designs are also recommended to take in outer heat sink design, such as FR4
PCB on Aluminum with thermal vias or FPC on Aluminum with thermal conductive adhesive, etc.

ufficient thermal management must be conducted, or the die junction temperature will be over
the limit under large electronic driving and LED lifetime will decrease critically.
