4.PACKAGING
The LEDs are packed in cardboard boxes
after taping.
Please refer to figure's page.
The label on the minimum packing unit shows ; Part Number, Lot Number, Ranking, Quantity
In order to protect the LEDs from mechanical shock, we pack them in cardboard boxes for transportation.
The LEDs may be damaged if the boxes are dropped or receive a strong impact against them,
so precautions must be taken to prevent any damage.
The boxes are not water resistant and therefore must be kept away from water and moisture.
When the LEDs are transported, we recommend that you use the same packing method as Nichia.
5.LOT NUMBER

7.CAUTIONS
White LEDs are devices which are materialized by combining Blue LEDs and special phosphors.
Consequently, the color of White LEDs is changed a little by an operating current.
Care should be taken after due consideration when using LEDs.
(1) Moisture Proof Package
When moisture is absorbed into the SMT package it may vaporize and expand during soldering.
There is a possibility that this can cause exfoliation of the contacts and damage to the optical
characteristics of the LEDs. For this reason, the moisture proof package is used to keep moisture
to a minimum in the package.
The moisture proof package is made of an aluminum moisture proof bag with a zipper. A package of
a moisture absorbent material (silica gel) is inserted into the aluminum moisture proof bag.
The silica gel changes its color from blue to pink as it absorbs moisture.
(2) Storage
Storage Conditions
Before opening the package :
The LEDs should be kept at 30C or less and 90%RH or less. The LEDs should be used within a
year. When storing the LEDs, moisture proof packaging with absorbent material (silica gel)
is recommended.
After opening the package :
The LEDs should be kept at 30C or less and 70%RH or less. The LEDs should be soldered
within 168 hours (7days) after opening the package. If unused LEDs remain, they should be
stored in moisture proof packages, such as sealed containers with packages of moisture absorbent
material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag
and to reseal the moisture proof bag again.
If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
time, baking treatment should be performed using the following conditions.
Baking treatment : more than 24 hours at 65 5C
Nichia LED electrode and leadframe are comprised of a silver plated copper alloy. The silver surface
may be affected by environments which contain corrosive gases and so on. Please avoid conditions
which may cause the LED to corrode, tarnish or discolor. This corrosion or discoloration might lower
solderability or might affect on optical characteristics.
Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
condensation can occur.
(3) Heat Generation
Thermal design of the end product is of paramount importance. Please consider the heat generation
of the LED when making the system design. The coefficient of temperature increase per input
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
The operating current should be decided after considering the ambient maximum temperature of LEDs.
