Photobiological safety of lamps and lamp systems - Part 7: Light sources and luminaires primarily emitting visible radiation
IEC 62471-7:2023 specifies an assessment of the photobiological safety of electrical light sources and luminaires in normal use as well as some basic product requirements. It applies to electrical light sources and luminaires that emit radiation predominantly in the visible spectral range (380 nm to 780 nm) and are used to illuminate spaces or objects or used for signalling.

Sécurité photobiologique des lampes et des appareils utilisant des lampes - Partie 7: Sources de lumière et luminaires qui émettent principalement un rayonnement visible
L'IEC 62471-7:2023 spécifie une évaluation de la sécurité photobiologique des sources de lumière électriques et des luminaires en utilisation normale ainsi que des exigences fondamentales pour les produits. Elle s'applique aux sources de lumière électriques et aux luminaires qui émettent des rayonnements principalement dans le domaine spectral visible (380 nm à 780 nm) et qui sont utilisés pour éclairer des espaces ou des objets ou utilisés pour la signalisation.
Fotobiološka varnost sijalčnih sistemov - 7. del: Svetlobni viri in svetilke, ki oddajajo predvsem vidno sevanje (IEC 62471-7:2023)
Standard IEC 62471-7:2023 določa postopek ocenjevanja fotobiološke varnosti električnih svetlobnih virov in svetilk v normalnih pogojih uporabe in tudi nekatere osnovne zahteve za izdelke. Uporablja se za električne svetlobne vire in svetilke, ki oddajajo sevanje predvsem v vidnem spektralnem območju (380 nm do 780 nm) in se uporabljajo za osvetlitev prostorov ali predmetov oziroma za signalizacijo.
