6. 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.
