(7) Cleaning

● The LEDs should not be cleaned with water, benzine, and/or thinner.

● If required, isopropyl alcohol (IPA) should be used. Other solvents may cause premature failure to the LEDs

due to the damage to the resin portion. The effects of such solvents should be verified prior to use.

In addition, the use of CFCs such as Freon is heavily regulated.

● When dust and/or dirt adheres to the LEDs, soak a cloth with Isopropyl alcohol (IPA), then squeeze it before wiping the LEDs.

● Ultrasonic cleaning is not recommended since it may have adverse effects on the LEDs

depending on the ultrasonic power and how LED is assembled.

If ultrasonic cleaning must be used, the customer is advised to make sure the LEDs will not be damaged prior to cleaning.

(8) Eye Safety

● In 2006, the International Electrical Commission (IEC) published IEC 62471:2006 Photobiological safety of lamps

and lamp systems, which added LEDs in its scope.

On the other hand, the IEC 60825-1:2007 laser safety standard removed LEDs from its scope.

However, please be advised that some countries and regions have adopted standards

based on the IEC laser safety standard IEC 60825-1:20112001, which still includes LEDs in its scope.

Most of Nichia's LEDs can be classified as belonging into either the Exempt Group or Risk Group 1.

High-power LEDs, that emit light containing blue wavelengths, may be classified as Risk Group 2.

Please proceed with caution when viewing directly any LEDs driven at high current, or viewing LEDs

with optical instruments which may greatly increase the damages to your eyes.

● Viewing a flashing light may cause eye discomfort. When incorporating the LED into your product,

please be careful to avoid adverse effects on the human body caused by light stimulation.

(9) Others

● 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 system, automobiles,

traffic control equipment, life support systems and safety devices).

● The customer shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent

from Nichia. When defective LEDs are found, the customer shall inform Nichia directly before disassembling or analysis.

● The specifications and appearance of this product may change without notice;

Nichia does not guarantee the contents of this specification. Both the customer and Nichia

will agree on the official specifications of supplied products before the volume production of a program begins.
