Question: Due to possible harmful radiation, what requirements are to be applied to LEDs?
: K. k/ a8 R1 z4 f- e7 ODecision: In principle, apply the requirements given in IEC/EN 60825-1 (*)-(#). However
7 \1 H- s, H6 U. }in order to avoid expensive measurements, luminaires provided with LEDs
should be treated as follows:
- If the light intensity is low, i.e. from a conventional LED for indication or signalling
purposes, the LED is most likely comparable with a laser of Class 1 according to IEC/EN
) P/ D: N$ i9 R4 h60825-1 (*)-(#) and consequently there is no need for measurements. During the
judgement, the covers, optics and similar parts that can be removed by hand, shall be

- In all other cases the luminaire manufacturer shall be asked to provide a declaration based

- If such a declaration is not provided or if judgement not possible, the measurements
given in IEC/EN 60825-1 (*)-(#) shall be performed. In the TRF, it is indicated that
measurements have been performed. For luminaires containing light sources providing
, `1 W. R* w" P$ C  nradiation according to Class 2 lasers, the luminaire shall be treated as a laser source
