Title (EN) SYSTEM FOR OPERATING AN ELECTRONIC LIGHT ARRANGEMENT
(FR) SYSTÈME DESTINÉ À FAIRE FONCTIONNER UN AGENCEMENT LUMINEUX ÉLECTRONIQUE
Abstract:
(EN) The present invention is related to a system (1) for operating an electronic light arrangement (2), comprising: - the light arrangement (2) with one primary group (2a) and at least one secondary group (2b) of light-emitting devices (30), - an electronic buck-boost-device (10) which is electrically connected to the primary group (2a) for providing a first constant current to the corresponding light-emitting devices (30) of the primary group (2a), - at least one electronic buck-device (20) which is electrically connected to the at least one secondary group (2b) for providing a second constant current to the corresponding light-emitting devices (30) of the secondary group (2b).
(FR) L'invention concerne un système (1) destiné à faire fonctionner un agencement lumineux électronique (2), comprenant : - l'agencement lumineux (2) constitué d'un groupe primaire (2a) et d'au moins un groupe secondaire (2b) de dispositifs électroluminescents (30) ; - un dispositif électronique dévolteur-survolteur (10) raccordé électriquement au groupe primaire (2a) pour fournir un premier courant constant aux dispositifs électroluminescents (30) correspondants du groupe primaire (2a) ; - au moins un dispositif dévolteur électronique (20) raccordé électriquement audit groupe secondaire (2b) au moins pour fournir un deuxième courant constant aux dispositifs électroluminescents (30) correspondants du groupe secondaire (2b).
