Param\u00e8tres TLA.<\/strong><\/strong><\/h3>\n\n

TLA (Temporal Light Artifacts) est d\u00e9crit par PstLM (scintillement < 80 Hz) et SVA (scintillement 80-2000 Hz). Voici les derni\u00e8res exigences de PstLM et SVM. <\/p>\n\n

Selon NEMA77 (2017 Temporal Light Artifacts : Test Methods and Guidance for Acceptance Criteria)<\/p>\n\n

Les pilotes LED uPowerTek sont tous au moins des alimentations \u00e0 d\u00e9coupage \u00e0 deux \u00e9tages et l’ondulation de sortie est trait\u00e9e avec soin, ainsi les param\u00e8tres TLA typiques sont les suivants.<\/p>\n\n

PstLM<0,02, SVM<0,05, m\u00e9thode d’essai selon IEC-61547-1.<\/p>\n\n

Et pour l’application d’\u00e9clairage sportif, il existe un autre param\u00e8tre qui affecte la diffusion en direct, en particulier pour les cam\u00e9ras haute r\u00e9solution et haute vitesse, le pourcentage de scintillement, et ce param\u00e8tre est pour la premi\u00e8re fois formellement r\u00e9glement\u00e9 par une norme chinoise \u00ab GB\/T38539 Exigences techniques pour l’application de l’\u00e9clairage sportif \u00e0 LED \u00bb.<\/p>\n\n

Et voici la valeur PF (pourcentage de scintillement) typique des pilotes LED non isol\u00e9s uPowerTek pour l’\u00e9clairage sportif :<\/p>\n\n

PF<1% Niveau de diffusion, selon GB\/T-38539-2020<\/p>\n\n

Options de gradation rapide. <\/strong><\/strong><\/h3>\n\n

La gradation rapide est essentielle pour une bonne performance dynamique des \u00e9clairages LED, notamment pour les applications sportives. C’est \u00e9galement une fonctionnalit\u00e9 li\u00e9e aux syst\u00e8mes de contr\u00f4le d’\u00e9clairage, notamment dans le contexte de l’\u00e9clairage intelligent ou des solutions d’\u00e9clairage avanc\u00e9es utilis\u00e9es dans les stades, les b\u00e2timents, les entrep\u00f4ts ou les environnements industriels. Elle d\u00e9signe la capacit\u00e9 d’un syst\u00e8me d’\u00e9clairage \u00e0 faire varier l’intensit\u00e9 lumineuse rapidement et en douceur en r\u00e9ponse \u00e0 des commandes. La gradation rapide inclut g\u00e9n\u00e9ralement des param\u00e8tres tels que le temps de transition marche-arr\u00eat et le temps de transition de 10 \u00e0 100 % de la puissance. <\/p>\n\n
