Precautions In Handling
1)
LED Lighting for white light are devices which are materialized by combining white LEDs.
T
he color of
w
hite light can differ
a
little unusually to diffuser plate(sign-board panel)
.
2)
Handling
-
Don
’t
drop the unit and don
’t
give the unit any shocks.
-
Don
’t
storage the Module in
a
dusty place or room.
-
Don
’t
take the unit to pieces.
3)
Cleaning
-
This LED Module should not be used in any type of fluid such as oil, organic solvent, etc.
-
It is recommended that IPA(Isopropyl Alcohol) be used as
a
solvent for cleaning the LED
Module.
-
When using other solvents, it should be confirmed beforehand whether the solvents will
dissolve the package and the resin or not. Freon solvents should not be used to clean
the LEDs because of worldwide regulations. Do not clean the LED Module by the ultrasonic.
-
Before cleaning,
a
pre-test should be done to confirm whether any damage to the LED
Lighting will occur.
4)
Static Electricity
-
Static electricity or surge voltage damages the LED Lighting.
5)
Discoloration
-
VOCs
(
volatile organic compounds) may be occurred by adhesives, flux, hardener or organic
additives which is used in luminaires
(
fixture) and LED silicone bags are permeable to it. It may
lead
a
discoloration when LED expose to heat or light.
-
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 know the physical properties for the
materials used in luminaires, it requires to select carefully.
6)
Risk of Sulfurization
(
or Tarnishing)
-
The lead frame from Samsung Electronics is
a
plated package and it may change to black
(
or dark colored) when it is exposed to Ag
(
a), Sulfur
(
S), Cchlorine
(
Cl) or other halogen compound.
It requires attention.
-
Sulfide
(
Sulfurization) of the lead frame may cause
a
change of degradation intensity, chromaticity
coordinates and it may cause open circuit in extreme cases. It requires attention.
-
Sulfide
(
Sulfurization) of the lead frame may cause of storage and using with oxidizing substances
together. Therefore, LED is not recommend to use and store with the below list.
:
Rubber, Plain paper, lead solder cream etc.
