9-3. 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.
