Question: Due to possible harmful radiation, what requirements are to be applied to LEDs?
8 v4 f* M+ M! L& i) s) e; pDecision: In principle, apply the requirements given in IEC/EN 60825-1 (*)-(#). However

- If the light intensity is low, i.e. from a conventional LED for indication or signalling

60825-1 (*)-(#) 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

with the limits given for Class 1 lasers in IEC/EN 60825-1 (*)-(#) and that no

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

' }* S  x/ b5 pLED module does not exceed the values given in IEC/EN 60825-1 (*)-(#) for Class 1
or1M lasers with or without optics. In the TRF, it is indicated that judgement is based on
manufacturer’s declaration.
- If such a declaration is not provided or if judgement not possible, the measurements
, X0 Z8 b9 N) E) a/ P' K; ?0 Ygiven 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
radiation according to Class 2 lasers, the luminaire shall be treated as a laser source
according to IEC/EN 60825-1 (*)-(#) and comply with the requirements given in that
standard.
