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 th e s tatic electrici ty and surge. It is recommen ded to use a wrist band or anti-electrostatic gl ove 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 character istics such as increase in leak cu r rent, 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
expos e d 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 select ed carefully.
4) Risk of sulfurization (or tarnishing)
The LED uses a silv er-plated lead frame and i ts surface col or 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 an d, 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 ar ea 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 con s id er the creep age and clearance distan ce at the end product.
