Le driver LED pour \u00e9clairage de secours est un \u00e9l\u00e9ment crucial qui garantit le bon fonctionnement des luminaires LED en cas de panne de courant ou d’urgence. Les pilotes de LED sont charg\u00e9s de r\u00e9guler le courant et la tension \u00e9lectriques fournis \u00e0 la source de lumi\u00e8re LED lorsqu’elle est aliment\u00e9e par la tension continue des batteries.<\/p>\n\n

\n Description g\u00e9n\u00e9rale<\/strong>\n <\/h2>\n\n

La r\u00e9glementation relative \u00e0 la marque EL est d\u00e9finie par l’annexe J de la norme IEC61347-2-13.<\/p>\n\n

\"p1<\/figure>\n\n
<\/div>\n\n

Le symbole de la marque EL est comme ci-dessous.<\/p>\n\n

\n Exigences EOFx<\/strong>\n <\/strong>\n <\/h2>\n\n

L’exigence cl\u00e9 de la marque EL est que le pilote de LED soit capable de produire un courant nominal pour garantir la puissance lumineuse en cas d’urgence ou s’il passe en mode d’urgence avec une entr\u00e9e de tension continue provenant des batteries.<\/p>\n\n

Et cette fonction est d\u00e9crite par EOFx (Emergency Output Factor) qui est mesur\u00e9e 5 s et 60 s apr\u00e8s la mise sous tension de l’appareillage de commande par entr\u00e9e CC. La valeur d’essai \u00e0 5 s avec une tension d’alimentation de secours maximale doit \u00eatre d’au moins 50 % de l’EOFx d\u00e9clar\u00e9e \u00e0 60 s.<\/p>\n\n

\"exigences<\/figure>\n\n
<\/div>\n\n

EOFx \u00e9galement programmable est une fonction utilis\u00e9e par de plus en plus de pilotes marqu\u00e9s EL, et elle aide les clients \u00e0 trouver un bon \u00e9quilibre entre le rendement lumineux et la dur\u00e9e en mode d’urgence en fonction des diff\u00e9rentes applications et exigences du march\u00e9.<\/p>\n\n

<\/div>\n\n

\n Capacit\u00e9 d’entr\u00e9e CC<\/strong>\n <\/strong>\n <\/h2>\n\n

Certains syst\u00e8mes d’\u00e9clairage de secours peuvent \u00eatre aliment\u00e9s par des sources CC, telles que des batteries ou des syst\u00e8mes d’\u00e9nergie renouvelable. Les pilotes de LED dot\u00e9s d’une capacit\u00e9 d’entr\u00e9e CC peuvent fonctionner efficacement avec ces sources d’alimentation sans avoir besoin de dispositifs de conversion suppl\u00e9mentaires.<\/p>\n\n

\n Sommaire<\/strong>\n <\/strong>\n <\/h2>\n\n

La marque EL est n\u00e9cessaire pour les syst\u00e8mes d’\u00e9clairage de secours et les pilotes de LED portant la marque EL doivent \u00eatre soigneusement s\u00e9lectionn\u00e9s en fonction des diff\u00e9rentes applications. EOFx programmable est une fonctionnalit\u00e9 int\u00e9ressante permettant aux utilisateurs de b\u00e9n\u00e9ficier d’une conception flexible.<\/p>\n","protected":false},"excerpt":{"rendered":"
