Subject: LEDs used as a light source in luminaires
Key words:
- LEDs
- Harmful radiation
- Light intensity
Meeting:
Decision confirmed at CTL 42nd meeting
; N, j& p5 f* j+ AQuestion: How to handle LEDs used in luminaires due to possible harmful radiation.
# n# ?0 W9 h5 g1 J) H4 T) iDecision: In principle apply the requirements given in IEC/EN 60825-1. However in order
+ v7 I$ L; u& H7 M9 A# D6 V- Nto avoid expensive measurements, the luminaires provided with LEDs should be

- If the light intensity is low, i.e. from a conventional LED for indication or signalling
- j. i# W6 g9 \. r. [, y* h9 `4 B# Hpurposes, the LED is most likely comparable with a laser of Class 1 according to
IEC/EN 60825-1 and consequently there is no need measurements. During the

removed. In the TRF it is indicated that the light intensity has been judged to comply

. Y/ q. y# V$ i+ o- In all other cases the luminaire manufacturer shall be asked to provide a declaration
* n/ ?! ^* b! [, m( h5 Qbased on relevant tests (e.g. from the LEDs manufacturer) showing that the radiation
from the LED module will not exceed the values given in IEC/EN 60825-1 for Class 1
or1M lasers with or without optics. In the TRF it is noted that judgements have been
based on a manufacturer declaration.
1 u8 [1 |5 t5 P3 j6 x- If such a declaration cannot be provided or if we are insecure on how to judge, the

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.
Information about the action taken in relation to the LED radiation should be given in the
