(7) Cleaning

● 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.

● Ultrasonic cleaning is not recommended for the LEDs since it may adversely effect on the LEDs

by the ultrasonic power and LED assembled condition.

If it is unavoidable, customer is advised to check prior to use that the cleaning will not damage the LEDs.

(8) Eye Safety

● 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 it 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. 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 greatly increase the hazard to your eyes.

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

precaution should be taken to avoid adverse effect on human body caused by the light stimulus.

(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.

● Customer and Nichia shall agree the official specification of supplied products prior to the start of a customer’s volume production.

● The appearance and specifications of the product may be modified for improvement without notice.
