Photobiological safety of lamps and lamp systems - Part 5: Image projectors

IEC 62471-5:2015(E) provides a risk group classification system for image projectors, and measurement conditions for optical radiation emitted by image projectors. It includes manufacturing requirements that may be required as a result of an image projector system being assigned to a particular risk group. Therefore, this part of IEC 62471 provides safety requirements for lamp systems that are intended to produce projected visible optical radiation, such as theatre projectors, data projectors and home-use projectors. The assigned risk group of a projector product also may be used by projector manufacturers to assist with any risk assessments, e.g. for occupational exposure in workplaces. National requirements may exist for the assessment of products or occupational exposure.

Photobiologische Sicherheit von Lampen und Lampensystemen - Teil 5: Photobiologische Sicherheit von Lampensystemen für Bildprojektoren

Sécurité photobiologique des lampes et des appareils utilisant des lampes – Partie 5: Projecteurs d’images

IEC 62471-5:2015 fournit des exigences concernant la sécurité photobiologique du rayonnement optique émis par les projecteurs d'images. Elle inclut les exigences de fabrication qui peuvent être exigées par suite de l'affectation d'un groupe de risques particulier à un appareil utilisant un projecteur d'images. Par conséquent, la présente partie de l’IEC 62471 fournit des exigences de sécurité pour les appareils utilisant des lampes qui sont destinés à générer des rayonnements optiques visibles projetés, tels que les projecteurs cinématographiques, les projecteurs d'image-écran et les projecteurs à usage domestique. Le groupe de risques affecté d'un projecteur peut également être utilisé par les fabricants de projecteurs pour faciliter les appréciations du risque, par exemple dans le cas de l'exposition professionnelle sur les lieux de travail. Il peut exister des exigences nationales pour l'évaluation des appareils ou de l'exposition professionnelle.

Fotobiološka varnost sijalčnih sistemov - 5. del: Slikovni projektorji

Ta del standarda IEC 62471 določa zahteve glede fotobiološke varnosti optičnega sevanja slikovnih projektorjev. Ta del standarda IEC 62471 ne obravnava drugih nevarnosti (npr. električne, mehanske ali požarne nevarnosti).
Ta del standarda IEC 62471 določa zahteve glede:
• ocena tveganja pri optičnem sevanju slikovnih projektorjev;
• tvegane skupine projektorjev;
• preskusni in meritveni pogoji;
• zahteve proizvajalca, vključno z uporabniškimi informacijami.
Področje uporabe tega dela standarda IEC 62471 je fotobiološka varnost slikovnih projektorjev, vključno
z emisijami projektorjev z lasersko osvetlitvijo, ki izpolnjujejo zahteve, določene v točki
4.4 standarda IEC 60825-1:2014, in za katere so bile emisije vidne svetlobe izključene iz
klasifikacije, podane v standardu IEC 60825-1.
Ta del standarda IEC 62471 ne obravnava varnostnih zahtev za laserske prikazovalnike,
pri katerih se uporabljajo kolimirani laserski žarki (celostno skenirani). Obravnava projektorje z lasersko osvetlitvijo,
ki z laserskim virom osvetlijo na primer mikro elektromehanski
sistem (MEMS) brez skeniranih žarkov ali projekcijski sistem z zaslonom iz tekočih kristalov.
OPOMBA: Slikovni projektorji, ki vključujejo laserske žarke, so predmet določil standarda IEC 60825-1, ki se uporabljajo za
vgrajen laser. Glej točko 4.4 standarda IEC 60825-1:2014 glede tega, katere emisije vidne svetlobe so bile izključene iz
klasifikacije laserskih izdelkov.
Ta del standarda IEC 62471 vključuje projektorje samo za vidno slikovno projekcijo in ne
vključuje ultravijoličnih (UV) projektorjev, infrardečih (IR) projektorjev, sijalk za splošno uporabo v razsvetljavi (GLS;
določeno v standardu IEC 62471) ali sistemov projektorskih sijalk, ki se uporabljajo za splošno razsvetljavo
in so obravnavani v ločenih mednarodnih standardih.
