<\/figure>\n\nConsid\u00e9rations de conception pour l’enfichage \u00e0 chaud<\/h2>\n\n
Mais la plupart des pilotes LED actuels ne prennent pas en charge cette fonction car ils n’ont pas pour fonction de limiter la tension \u00e0 vide et la tension LED de sortie maximale. Il y a deux consid\u00e9rations de conception sp\u00e9ciales pour cette innovation :<\/p>\n\n
1.La tension de sortie \u00e0 vide du pilote LED doit \u00eatre contr\u00f4l\u00e9e. <\/h3>\n\n
La plupart des pilotes normaux r\u00e8glent la tension de sortie de 10 \u00e0 20% sup\u00e9rieure \u00e0 la valeur de fonctionnement maximale et lors du branchement d’une barre de LED sur la sortie du pilote, il peut y avoir un grand courant d’appel des condensateurs de sortie du pilote de LED aux barres de LED conduisant ainsi \u00e0 la D\u00e9faillance de la barre LED. Ainsi, le pilote de LED doit avoir la capacit\u00e9 de d\u00e9tecter la condition de fonctionnement sans charge et d’abaisser la tension de sortie \u00e0 la valeur tr\u00e8s proche de la barre de LED sur le seuil de tension.<\/p>\n\n
2. La tension de sortie maximale du pilote LED doit \u00e9galement \u00eatre contr\u00f4l\u00e9e. <\/h3>\n\n
Supposons que deux barres soient retir\u00e9es d’un appareil \u00e0 8 barres, les 6 barres restantes auront une surcharge de 33\u00a0% et un risque accru de d\u00e9faillance.<\/p>\n\n

<\/figure>\n\nPour \u00e9viter que la barre ne surchauffe, selon la courbe LED iv, si la tension du pilote peut \u00eatre limit\u00e9e, le courant peut \u00eatre contr\u00f4l\u00e9 \u00e0 une certaine valeur.<\/p>\n\n uPowerTek fournit la solution pour le remplacement \u00e0 chaud. Les utilisateurs peuvent d\u00e9finir les param\u00e8tres de remplacement \u00e0 chaud de la tension de seuil et de la tension directe dans l’utilitaire de programmation uPowerTek.<\/p>\n\n La conception unique d’uPowerTek r\u00e9sout les probl\u00e8mes d’\u00e9change des barres de LED en mode de fonctionnement et il convient \u00e9galement de rappeler que cette fonctionnalit\u00e9 ne doit \u00eatre effectu\u00e9e que par les pilotes de LED avec une tension de s\u00e9curit\u00e9 inf\u00e9rieure \u00e0 60 Vcc (tension de classe 2 ou SELV).<\/p>\n\n Aujourd’hui, les appareils USB enfichables \u00e0 chaud sont fr\u00e9quemment utilis\u00e9s dans notre vie quotidienne, alors que diriez-vous de fournir la fonction d’enfichage \u00e0 chaud aux luminaires modulaires \u00e0 LED\u00a0? Il s’agit d’une fonctionnalit\u00e9 int\u00e9ressante fournie par des soci\u00e9t\u00e9s telles que Photontek et Lumatek et qui r\u00e9alise le remplacement \u00e0 chaud des barres LED.
