- h, i, y# }  l$ j8 nQuestion: Due to possible harmful radiation, what requirements are to be applied to LEDs?
Decision: In principle, apply the requirements given in IEC/EN 60825-1 (*)-(#). However
5 h+ R9 D; b% `  R5 ein order to avoid expensive measurements, luminaires provided with LEDs
should be treated as follows:
7 `6 p' ~' |  d: R- C- 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
60825-1 (*)-(#) and consequently there is no need for measurements. During the
# @$ \5 z, @6 k9 ^judgement, the covers, optics and similar parts that can be removed by hand, shall be
' ?( b4 t9 H6 p- W$ H- Oremoved. In the TRF, it is indicated that the light intensity has been judged to comply
& ~: l, ~% r' b0 uwith the limits given for Class 1 lasers in IEC/EN 60825-1 (*)-(#) and that no
! y7 l2 {# f, b+ A, ^' N8 ]  y& emeasurement is made.
- In all other cases the luminaire manufacturer shall be asked to provide a declaration based
2 t3 O3 I( M# `5 c5 z$ x! H/ }on relevant tests (e.g. from the LEDs manufacturer) showing that the radiation from the
LED 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
& r- {* `+ C% B# F; A5 @: ?given in IEC/EN 60825-1 (*)-(#) shall be performed. In the TRF, it is indicated that
0 L/ ^) ]3 l! J; k# j5 m1 T4 n: f8 hmeasurements 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
