Abstract

On accorde une importance croissante à l'industrie verte pour économiser de l'énergie. Les lampes d'éclairage à DEL se sont largement répandues dans ce domaine, mais les lampes fluorescentes à tubes en verre existantes n'ont pas encore été remplacées par des lampes à DEL de manière extensive, parce que le remplacement de lampes fluorescentes existantes par des lampes à DEL nécessite des processus de remplacement très difficiles consistant à retirer les stabilisateurs des lampes fluorescentes existantes, lesquels ont été installés dans des dispositifs à lampes fluorescentes, et à réinstaller des convertisseurs à DEL. Une lampe à DEL selon la présente invention utilise une puissance en CA, laquelle est produite par un stabilisateur de lampe fluorescente, sans modification pour piloter la lampe à DEL. L'installation d'une lampe à DEL est donc réalisée simplement en remplaçant une lampe fluorescente de type tube en verre par une lampe à DEL selon la présente invention tandis que les dispositifs à lampes fluorescentes existants, y compris le stabilisateur de lampe fluorescente, sont utilisés sans modification. Dans ce cas, cependant, la lampe à DEL doit satisfaire les normes de sécurité des produits électriques, K10025, annoncées le 25 janvier 2013 par l'agence coréenne pour la technologie et les normes, laquelle nécessite qu'une lampe à DEL ait des fonctions de sécurité, par exemple une fonction de prévention contre les incendies, une fonction opérationnelle en zone sûre, etc., y compris une fonction d'interruption de courant de choc. La présente invention rend possible qu'une lampe à DEL remplaçant une lampe fluorescente satisfasse les normes de sécurité K10025 sans modifier l'extérieur d'une lampe fluorescente existante. La présente invention apportera donc une grande contribution à l'usage étendu de lampes à DEL remplaçant des lampes fluorescentes.
