Title
(EN) LIGHTING CIRCUITRY OF VEHICLE
(FR) CIRCUITS D'ÉCLAIRAGE DE VÉHICULE
Abstract
(EN)
A lighting circuitry (200) of a vehicle (100), comprising: a microcontroller (110), a plurality of lighting loads (140, 150, 170) electrically coupled to the microcontroller (110) and operated through a plurality of the switches (S1, S2, S3, S4, S5, S6), a driver (120) configured to deliver constant current to the plurality of lighting loads (140, 150, 170), a detection module (160) to detect status of at least one of the plurality of lighting loads (140, 150, 170) and configured to communicate status of the at least one of the plurality of lighting loads (140, 150, 170) to the microcontroller (110); and at least one electric limiting path (210) electrically closes, wherein the microcontroller (110) configured to electrically close the at least one electric limiting path (210), when the detection module (160) communicates to the microcontroller (110) status of the at least one of the plurality of lighting loads (140, 150, 170) as electrically open.
(FR)
Circuits d'éclairage (200) d'un véhicule (100), comprenant : un micro-dispositif de commande (110), une pluralité de charges d'éclairage (140, 150, 170) couplées électriquement au micro-dispositif de commande (110) et actionnées par l'intermédiaire d'une pluralité des commutateurs (S1, S2, S3, S4, S5, S6), un pilote (120) conçu pour délivrer un courant constant à la pluralité de charges d'éclairage (140, 150, 170), un module de détection (160) pour détecter l'état d'au moins une charge de la pluralité de charges d'éclairage (140, 150, 170) et conçu pour communiquer l'état de la ou des charges d'éclairage de la pluralité de charges d'éclairage (140, 150, 170) au micro-dispositif de commande (110) ; et au moins un chemin de limitation électrique (210) se ferme électriquement, le micro-dispositif de commande (110) étant conçu pour fermer électriquement le ou les chemins de limitation électrique (210), lorsque le module de détection (160) communique au micro-dispositif de commande (110) l'état de la ou des charges de la pluralité de charges d'éclairage (140, 150, 170) comme étant électriquement ouvert.
