(2) Installation
· The following figure shows the Luminous Flux Standard LED should be held by a holder.
Example 1:
(Held by the part with 25mm diameter)
Example 2:
(Held by the part with 20mm diameter)
A holder
A holder
· The measurement distance shall start from the top surface of the LED. Please refer to
“OUTLINE DIMENSIONS” on the following page.
(3) Measurement
· The Standard LED should be measured when the luminous flux has stabilized after the
start of temperature control and constant current drive.
Typically, the standard LED will be stable and ready to be used for calibration within 1 to 3 minutes.
Please refer to “TYP.CHARACTERISTICS” on the following page for the characteristics during
the first 5 minutes after the LED starts emission.
11.CAUTIONS
(1) Storage
· This product should be kept at 30°C or less and 70%RH or less. When storing, moisture proof
packaging with absorbent material (silica gel) is recommended.
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
condensation can occur.
(2) Static Electricity
· Static electricity or surge voltage damages the LEDs.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that precautions
be taken against surge voltage to the equipment that mounts the LEDs.
· When inspecting the final products in which LEDs were assembled, it is recommended to check
whether the assembled LEDs are damaged by static electricity or not.
It is easy to find
static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended).
· Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,
or the LEDs do not light at the low current.

(3) Safety Guideline for Human Eyes
· The International Electrical Commission (IEC) published in 2006 IEC 62471:2006
Photobiological
safety of lamps and lamp systems
which includes LEDs within its scope. Meanwhile LEDs were
removed from the scope of the IEC 60825-1:2007 laser safety standard, the 2001 edition of which
included LED sources within its scope. However, keep in mind that some countries and regions have
adopted standards based on the IEC laser safety standard IEC 60825-1:2001 which includes LEDs
within its scope.
Following IEC 62471:2006, most of Nichia LEDs can be classified as belonging to either Exempt
Group or Risk Group 1. Optical characteristics of a LED such as output power, spectrum and light
distribution are factors that affect the risk group determination of the LED. Especially a high-power
LED, that emits light containing blue wavelengths, may be in Risk Group 2.
Great care should be taken when viewing directly the LED driven at high current or the LED with
optical instruments, which may greatly increase the hazard to your eyes.
(4) Others
· Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had LEDs
incorporated into it.
· This product is designed to be used for calibration. Do not use this product for any other purposes or
other applications.
· User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written
consent from Nichia.
When defective LEDs are found, the User shall inform Nichia directly before
disassembling or analysis.
· The formal specifications must be exchanged and signed by both parties before purchase.
· The appearance and specifications of the product may be modified for improvement without notice.
