Aerospace series - Spectral quality of LED luminaires used with photoluminescent marking systems

This document defines a measure for the spectral quality of LED luminaires in terms of the ratio of the amount of visual light emitted by the luminaire versus the amount effective for charging photoluminescent products contained in that spectrum.
Fulfilment of this document by a LED luminaire will ensure general compatibility of the luminaire with photoluminescent marking systems.
This document alone does not provide any means of compliance to fulfil any airworthiness requirements.
For a specific aircraft installation, the spectral power distribution and illuminance at the photoluminescent marking systems are relevant.

Luft- und Raumfahrt - Spektrale Qualität von LED Leuchten zur Verwendung mit langnachleuchtenden Markierungssystemen

Dieses Dokument definiert eine Maßzahl für die spektrale Qualität von LED-Leuchten in Bezug auf das Verhältnis zwischen der Menge des abgegebenen sichtbaren Lichts und dem für die Aufladung langnach-leuchtender Produkte wirksamen Anteil dieses Spektrums.
Entspricht eine LED-Leuchte diesem Dokument stellt dies eine allgemeine Kompatibilität der Leuchte mit langnachleuchtenden Markierungssystemen sicher.
Dieses Dokument allein liefert kein Mittel zur Erfüllung jeglicher Anforderungen an die Lufttüchtigkeit.
Für spezifische Einbauten an Luftfahrzeugen sind die spektrale Leistungsverteilung und die Beleuchtungsstärke am Einbauort der langnachleuchtenden Markierungssysteme relevant.

Série aérospatiale - Qualité spectrale des luminaires à diodes électroluminescentes appliquées aux systèmes de marquage photoluminescents

Le présent document définit une mesure de la qualité spectrale des luminaires à diodes électroluminescentes en termes de rapport entre la quantité de lumière visuelle émise par le luminaire et la quantité efficace pour charger les produits photoluminescents contenus dans ce spectre.
Le respect du présent document par un luminaire à diodes électroluminescentes assure la compatibilité générale du luminaire avec les systèmes de marquage photoluminescents.
Le présent document à lui seul ne fournit aucun moyen de se conformer aux exigences de navigabilité.
Pour l’installation spécifique d'un aéronef, la distribution spectrale de puissance et l'éclairement des systèmes de marquage photoluminescents sont pertinents.

Aeronavtika - Spektralna kakovost LED-svetilk, ki se uporabljajo s fotoluminiscenčnimi sistemi označevanja

Ta evropski standard opredeljuje meritev spektralne kakovosti LED-sijalk v smislu razmerja med količino vidne svetlobe, ki jo odda svetilka, in dejansko količino svetlobe, potrebno za polnjenje fotoluminiscenčnih izdelkov tega spektra.
Izpolnjevanje tega evropskega standarda za LED-sijalke bo zagotovila splošno skladnost svetilk s sistemi za fotoluminiscenčno označevanje.
Ta evropski standard sam po sebi ne vsebuje nobenega načina usklajevanja za izpolnjevanje zahtev glede plovnosti.
Za posebne letalske instalacije je pomembna porazdelitev spektralne moči in osvetljenost sistemov za fotoluminiscenčno označevanje.
