9ꢀ6. Heat generation
ꢀ As this product is designed with consideration of the heat release property of module,
a heat release design is required to use this product efficiently.
Please ensure that heat generation is not in excess of the absolute maximum rating.
(Refer to 4ꢀ1 Performance)
ꢀ Factors responsible for an increase in temperature include heat generation attributed to
ambient temperature conditions or power dissipation. Thus, drive conditions should be
taken into consideration, depending on ambient temperature (Ta).
* Citizen Electronics cannot guarantee if usage exceeds this recommended conditions.
Please use it after sufficient verification is carried out on your own risk if necessary.
9ꢀ7. 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 highꢀpower 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 60825ꢀ1 /
Edition 1.2 “laser safety standard”, published 2001 were removed from the scope of
the IEC 60825ꢀ1 / 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 60825ꢀ1:2001 which includes LEDs within its scope.
9ꢀ7. Other
ꢀThis product complies with RoHS directives.
