Question: 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
$ `9 F1 O& e( \9 yin order to avoid expensive measurements, luminaires provided with LEDs
$ o5 ^% J" [# {0 z( |. ]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
0 B1 B& s& f6 {2 M. C! }60825-1 (*)-(#) and consequently there is no need for measurements. During the
  \" i" l" E. m( t9 G  V: ^2 fjudgement, the covers, optics and similar parts that can be removed by hand, shall be
removed. In the TRF, it is indicated that the light intensity has been judged to comply
with the limits given for Class 1 lasers in IEC/EN 60825-1 (*)-(#) and that no
7 I0 _% A2 l! N5 n- kmeasurement is made.
- In all other cases the luminaire manufacturer shall be asked to provide a declaration based
; y3 s6 J/ f  T7 Y' Ron 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.
