7. Precautions in Handling & Use
1) This LED Module should not be used in any type of fluid such as water, oil, organic solvent, etc. When washing is required, IPA is
recommended to use. When using other solvents it should be confirmed beforehand whether the solvents may react with the Module
material. The banned freon solvents should not be used. Do not clean using ultrasonic cleaner.
2) The LEDs are sensitive to the static electricity and surge. It is recommended to use a wrist band or anti-electrostatic glove when handling
the LED Modules. 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 leak current, lowered turn-on voltage, or
abnormal lighting of LEDs at low current.
3) 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 encapsulant when they
exposed to heat or light. This phenomenon can cause a significant loss of light emitted (output) from the luminaires (fixtures). In order
to prevent these problems, we recommend users to know the physical properties of the materials used in luminaires, and they must be
selected carefully.
4) Risk of sulfurization (or tarnishing)
The LED uses a silver-plated lead frame and its surface color may change to black (or dark colored) when it is exposed to sulfur (S),
chlorine (Cl) or other halogen compound. Sulfurization of lead frame may cause intensity degradation, change of chromaticity
coordinates and, in extreme cases, open circuit. It requires caution. Due to possible sulfurization of lead frame, the LED Modules
should not be used and stored together with oxidizing substances made of materials such as rubber, plain paper, lead solder cream, etc.
5) The resin area is very sensitive, please do not handle, press, touch or rub it.
6) Do not drop the Module or give shocks.
7) Do not store the Module in a dusty place or humid location.
8) Do not disassemble the Module.
9) Do not directly look into the lighted LED with naked eyes for a long period of time.
10) Please consider the creepage and clearance distance at the end product.
