8. Precautions

1. Avoid the application of any stress to the resin portion.

2. Avoid any contact by a sharp metal nail or other materials with the resin portion.

3. This product should be secured firmly by fastening an M3 screw on both sides of the product.

Please be careful not to apply any stress to the product during the clamping operation.

please check thoroughly.

4. Insulation between the terminal section and the heat sink section of the LED is not covered

by warranty. With regard to insulation after this product has been assembled in an apparatus,

preventive action should be carried out by the customer.

5. For fixing this product to the outer heat sink, heat grease should be applied to the whole rear

surface so that the product can dissipate heat as a whole. Please pay attention to avoid product

deformation when conducting the clamping operation with heat grease in sheet form.

6. Handling of static electricity

- These products are sensitive to static electricity charge.

Please take measures to prevent any static electricity being produced such as the wearing of a

wristband or anti-static gloves when handling this product.

- 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.

- ESD sensitivity of this product is 1000V (HBM, based on JEITA ED-4701/304).

- 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.

12. Eye Safety

- The International Electrical Commission (IEC) published in 2006 IEC 62471

”2006 Photobiological safety oflamps and lamp systems

” which includes LEDs within its scope.

When sorting single LEDs according to IEC 62471, most LEDs can be classified as belonging to

either Exempt Group or Risk Group 1.

- Optical characteristics of LEDs such as radiant flux, spectrum and light distribution are factors

that affect the risk group determination of the LED, and especially a high-power LED,

that emits light containing blue wavelengths, may have properties equivalent to those of Risk Group 2.

- Great care should be taken when directly viewing an LED that is driven at high current,

has multiple uses as a module or when focusing the light with optical instruments,

as these actions may greatly increase the hazard to your eyes.

- In addition, LED sources that were included within the scope of IEC 60825-1 /

Edition 1.2 “laser safety standard”, published 2001 were removed from the scope of

the IEC 60825-1 / Edition 2.0 revised 2007.

- 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.
