(6) 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 leak current remarkably
increases, the forward voltage becomes lower, or the LEDs do not light at the low current.
Criteria : (VF > 2.0V at IF=0.5mA)
(7) Safety Guideline for Human Eyes
· In 1993, the International Electric Committee (IEC) issued a standard concerning laser product safety
(IEC 825-1). Since then, this standard has been applied for diffused light sources (LEDs) as well
as lasers. In 1998 IEC 60825-1 Edition 1.1 evaluated the magnitude of the light source.
In 2001 IEC 60825-1 Amendment 2 converted the laser class into 7 classes for end products.
Components are excluded from this system. Products which contain visible LEDs are now classified
as class 1. Products containing UV LEDs are class 1M. Products containing LEDs can be classified
as class 2 in cases where viewing angles are narrow, optical manipulation intensifies the light, and/or the
energy emitted is high. For these systems it is recommended to avoid long term exposure.
It is also recommended to follow the IEC regulations regarding safety and labeling of products.
(8) Others
· NSPWR70BS complies with RoHS Directive.
· Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating
when using the LEDs with matrix drive.
· 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.
· The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such
as office equipment, communications equipment, measurement instruments and household appliances).
Consult Nichia’s sales staff in advance for information on the applications in which exceptional quality
and reliability are required, particularly when the failure or malfunction of the LEDs may directly
jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor
control systems, automobiles, traffic control equipment, life support systems and safety devices).
· 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 large volume purchase begins.
· The appearance and specifications of the product may be modified for improvement without notice.
· Please refer to the Nichia LEDs’technical documentation for circuit design or assembly.
