(8) Eye Safety

● There may be two important international specifications that should be noted for safe use of the LEDs: IEC 62471:2006

Photobiological safety of lamps and lamp systems and IEC 60825-1:2001 (i.e. Edition 1.2) Safety of Laser Products - Part 1:

Equipment Classification and Requirements. Ensure that when using the LEDs, there are no issues with the following points:

- LEDs have been removed from the scope of IEC 60825-1 since IEC 60825-1:2007 (i.e. Edition 2.0) was published. However,

depending on the country/region, there are cases where the requirements of the IEC 60825-1:2001 specifications or

equivalent must be adhered to.

- LEDs have been included in the scope of IEC 62471:2006 since the release of the specification in 2006.

- Most Nichia LEDs will be classified as the Exempt Group or Risk Group 1 according to IEC 62471:2006. However, in the case

of high-power LEDs containing blue wavelengths in the emission spectrum, there are LEDs that will be classified as Risk

Group 2 depending on the characteristics (e.g. radiation flux, emission spectrum, directivity, etc.)

- If the LED is used in a manner that produces an increased output or with an optic to collimate the light from the LED, it may

cause damage to the human eye.

● If an LED is operated in a manner that emits a flashing light, it may cause health issues (e.g. visual stimuli causing eye discomfort).

The system should be designed to ensure that there are no harmful effects on the human body.

(9) Miscellaneous

● Nichia warrants that the discrete LEDs will meet the requirements/criteria as detailed in the Reliability section within this

specification. If the LEDs are used under conditions/environments deviating from or inconsistent with those described in this

specification, the resulting damage and/or injuries will not be covered by this warranty.

● Nichia warrants that the discrete LEDs manufactured and/or supplied by Nichia will meet the requirements/criteria as detailed in

the Reliability section within this specification; it is the customer’s responsibility to perform sufficient verification prior to use to

ensure that the lifetime and other quality characteristics required for the intended use are met.

● The applicable warranty period is one year from the date that the LED is delivered. In the case of any incident that appears to be

in breach of this warranty, the local Nichia sales representative should be notified to discuss instructions on how to proceed while

ensuring that the LED in question is not disassembled or removed from the PCB if it has been attached to the PCB. If a breach of

this warranty is proved, Nichia will provide the replacement for the non-conforming LED or an equivalent item at Nichia’s

discretion. FOREGOING ARE THE EXCLUSIVE REMEDIES AVAILABLE TO THE CUSTOMER IN RESPECT OF THE BREACH OF THE

WARRANTY CONTAINED HEREIN, AND IN NO EVENT SHALL NICHIA BE RESPONSIBLE FOR ANY INDRECT, INCIDENTAL OR

CONSEQUENTIAL LOSSES AND/OR EXPENSES (INCLUDING LOSS OF PROFIT) THAT MAY BE SUFFERED BY THE CUSTOMER

ARISING OUT OF A BREACH OF THE WARRANTY.

● NICHIA DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

● This LED is intended to be used for general lighting, household appliances, electronic devices (e.g. mobile communication devices)

and automobiles; it is not designed or manufactured for use in applications that require safety critical functions (e.g. aircraft,

combustion equipment, life support systems, nuclear reactor control system, safety devices, spacecraft, submarine repeaters,

traffic control equipment, trains, vessels, etc.). If the LEDs are planned to be used for these applications, unless otherwise

detailed in the specification, Nichia will neither guarantee that the LED is fit for that purpose nor be responsible for any resulting

property damage, injuries and/or loss of life/health.

● The customer will not reverse engineer, disassemble or otherwise attempt to extract knowledge/design information from the LED.

● All copyrights and other intellectual property rights in this specification in any form are reserved by Nichia or the right holders who

have granted Nichia permission to use the content. Without prior written permission from Nichia, no part of this specification may

be reproduced in any form or by any means.

● Both the customer and Nichia will agree on the official specifications for the supplied LEDs before any programs are officially

launched. Without this agreement in writing (i.e. Customer Specific Specification), changes to the content of this specification

may occur without notice (e.g. changes to the foregoing specifications and appearance, discontinuation of the LEDs, etc.).
