Precautions (1)
1. Storage
· Moisture proof and anti-electrostatic package with moisture absorbent material is used, to keep moisture to a
minimum.
· Before opening the package, the product should be kept at 30or less and humidity less than 60% RH, and be used
within a year.
· After opening the package, the product should be stored at 30or less and humidity less than 10%RH, and be
soldered within 24 hours (1 days). It is recommended that the product be operated at the workshop condition of 30
or less and humidity less than 60%RH.
· If the moisture absorbent material has fade away or the LEDs have exceeded the storage time, baking treatment
should be performed based on the following condition: (80±5)for 24 hours.
2. Static Electricity
Static electricity or surge voltage damages the LEDs. Damaged LEDs will show some unusual characteristics such
as the forward voltage becomes lower, or the LEDs do not light at the low current., even not light.
All devices, equipment and machinery must be properly grounded. At the same time, it is recommended that wrist
bands or anti-electrostatic gloves, anti-electrostatic containers be used when dealing with the LEDs.
3. Design Consideration
In designing a circuit, the current through each LED must not exceed the absolute maximum rating specified for
each LED. In the meanwhile, resistors for protection should be applied, otherwise slight voltage shift will cause big
current change, burn out may happen.
It is recommended to use Circuit A which regulates the current flowing through each LED rather than Circuit B.
When driving LEDs with a constant voltage in Circuit B, the current through the LEDs may vary due to the variation in
Forward Voltage (VF) of the LEDs. In the worst case, some LED may be subjected to stresses in excess of the Absolute
Maximum Rating.
(A) (B)
Preferable
Non-Preferable
Thermal Design is paramount importance because heat generation may result in the Characteristics decline, such as
brightness decreased, Color changed and so on. Please consider the heat generation of the LEDs when making the
system design.
