Question: Due to possible harmful radiation, what requirements are to be applied to LEDs?- J3 P/ `7 F c8 a1 {( Y7 X
Decision: In principle, apply the requirements given in IEC/EN 60825-1 (*)-(#). However) L8 C5 K* J5 {! [0 G! t& l
in order to avoid expensive measurements, luminaires provided with LEDs

purposes, the LED is most likely comparable with a laser of Class 1 according to IEC/EN

- In all other cases the luminaire manufacturer shall be asked to provide a declaration based' ?$ d3 W' e$ l( r. I' o1 y* G
on relevant tests (e.g. from the LEDs manufacturer) showing that the radiation from the# \, B6 C+ H/ X: C4 |
