Precaution for use
1)
For over current-protection
,
customers are recommended to apply resistors
connected in series with the LEDs to mitigate
s
udden change of the forward current
caused by shift of the forward voltage.
2) This device should not be used in any type of fluid such as water, oil, organic
solvent, etc.
When cleaning is required, IPA is recommended as cleaning agent
.
Solvent-based c leaning agent such as Zestron
(
R)
may damage the silicone resins used in
the device.
3)
When the device is in operation
,
the forward current should be carefully determined
considering the maximum ambient temperature and the corresponding junction
temperature
.
4)
LEDs must be stored in
a
clean environment
.
If the LEDs are to be stored for
3
months or more after being shipped from SAMSUNG ELECTRONICS
,
they should be
packed with
a
nitrogen
-
filled container.
(
Shelf life of sealed bags:
12
months, temp.
0~40
℃
, 0~90%
RH
)
5)
After storage bag is open, device s ubject to soldering, solder reflow
,
or other
high temperature processes must be
:
a. Mounted within
672
hours
(28
days) at an assembly line with
a
condition of no
more than
30
℃
/60%
RH
.
b. Stored at
<10%
RH
.
6)
Repack unused Products with anti-moisture packing, fold to close any opening and
then store in
a
dry place.
7)
Devices require baking before mounting, if
h
umidity card reading reaches
60%
at
23±5
℃
.
8) D
evices must be baked for
1
hours at
60±5
℃
,if
baking is required
.
9)
Th
e
LEDs are sensitive to the static electricity and surge current
.
It is recommended to
use
a
wrist band or anti-electrostatic glove when handling the LEDs.
If voltage exceeding the absolute maximum rating is applied to LEDs, it may cause
damage or even destruction to LED devices.
Damaged LEDs may show some unusual characteristics such as increase in leakage
current, lowered turn-on voltage, or abnormal lighting of LEDs at low current.
10)
VOCs
(
volatile organic compounds) can be generated from adhesives, flux, hardener or
organic additives used in luminaires
(
fixtures). Transparent LED silicone encapsulant is
permeable to those chemicals and they may lead
a
discoloration of encapsualnt when
they expose to heat or light. This phenomenon can cause
a
significant loss of light
emitted(output) from the luminaires(fixtures). This phenomenon can give
a
significant
loss of light emitted(output) from the luminaires(fixtures). In order to prevent these
problems, we recommend you to k now the physical properties of materials used in
luminaires, They must be selected carefully.
