pilote LED<\/a> a une valeur sp\u00e9cifi\u00e9e. Normalement, lorsqu’il n’y a pas de communication de donn\u00e9es, la ligne de commande commune dans le syst\u00e8me DALI est de 16 V et la tension est fournie par l’alimentation interne DALI.<\/p>\n\nCombien d’alimentations le syst\u00e8me DALI peut-il supporter ?<\/h2>\n\n
Un syst\u00e8me DALI standard peut transporter jusqu’\u00e0 64 alimentations \u00e0 adresses ind\u00e9pendantes. Le courant maximum fourni par le syst\u00e8me DALI est de 250MA, ce qui est une limitation du syst\u00e8me DALI.<\/p>\n\n
Jusqu’\u00e0 64 pilotes LED num\u00e9riques peuvent \u00eatre connect\u00e9s \u00e0 la ligne DALI, quels que soient les n\u0153uds du syst\u00e8me et les limitations de courant d’alimentation.<\/p>\n\n
Si un \u00e9l\u00e9ment de commande conforme au protocole DALI est utilis\u00e9, la taille du syst\u00e8me doit respecter 64 points ou un courant total de 250mA. Lorsque le syst\u00e8me comprend \u00e0 la fois un pilote de LED et des composants de contr\u00f4le, il convient de s’assurer que le syst\u00e8me respecte ces restrictions. Si un syst\u00e8me DALI d\u00e9passe 64 points ou si le courant du syst\u00e8me est sup\u00e9rieur \u00e0 250 mA, le signal sera att\u00e9nu\u00e9, d\u00e9form\u00e9 et provoquera des erreurs syst\u00e8me. Certains composants peuvent ne pas \u00eatre en mesure de communiquer et le syst\u00e8me fonctionnera de mani\u00e8re instable.<\/p>\n\n
Quelles sont les exigences particuli\u00e8res pour les lampes ou les sources lumineuses lors de l’utilisation du syst\u00e8me DALI\u00a0?<\/h2>\n\n
Nous savons que le syst\u00e8me DALI donne de nouvelles connotations aux lampes. Chaque lampe peut avoir une adresse ind\u00e9pendante. Par cons\u00e9quent, les lampes sont pass\u00e9es de lampes ordinaires \u00e0 des \u00ab\u00a0lampes intelligentes\u00a0\u00bb. Les lampes intelligentes n’ont aucune exigence modifi\u00e9e pour les sources lumineuses et les luminaires, mais elles exigent que les pilotes de LED et les transformateurs \u00e9lectroniques soient conformes aux normes DALI. Le pilote LED DALI et les transformateurs num\u00e9riques ont les caract\u00e9ristiques d’ind\u00e9pendance, refl\u00e9tant ainsi l’adresse de la lampe.<\/p>\n\n
En plus des pilotes LED et des transformateurs, d’autres composants (tels que des capteurs) du syst\u00e8me DALI doivent \u00e9galement \u00eatre conformes aux normes DALI, formant ainsi un syst\u00e8me de contr\u00f4le d’\u00e9clairage DALI complet.<\/p>\n","protected":false},"excerpt":{"rendered":"
Quelles sont les exigences concernant la longueur de la ligne de commande du syst\u00e8me DALI\u00a0? La longueur de la ligne de commande doit r\u00e9pondre aux exigences de chute de tension.
