(8) Safety Guideline for Human Eyes
· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs.
· Do not clean the LEDs by the ultrasonic.
· Static electricity or surge voltage damages the LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that precautions
· When inspecting the final products in which LEDs were assembled, it is recommended to check
· Damaged LEDs will show some unusual characteristics such as the leak current remarkably
· The International Electrical Commission (IEC) published in 2006 IEC 62471:2006 Photobiological
other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the
resin or not.
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.
Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.

static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended).
increases, the forward voltage becomes lower, or the LEDs do not light at the low current.
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 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.
Following IEC 62471:2006, most of Nichia LEDs can be classified as belonging to either Exempt
Group or Risk Group 1. Optical characteristics of a LED such as output power, spectrum and light
distribution are factors that affect the risk group determination of the LED. 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 may greatly increase the hazard to your eyes.
