A lighting device comprises a light engine (102) with one or more LEDs (104), a drive circuit (108) coupled to the light engine (102) and energized the light engine (102) with a drive signal current, and a protection device (114) coupled to the drive circuit (108). The protection device (104) comprises a fault switch (234) having a position that maintains the drive signal current at or below a level that permits continued operation of the light engine (102) during a failure condition in the lighting device.
L'invention porte sur un dispositif d'éclairage, lequel dispositif comprend un moteur de lumière (102) avec une ou plusieurs diodes électroluminescentes (104), un circuit d'attaque (108) couplé au moteur de lumière (102) et alimentant le moteur de lumière (102) avec un courant de signal d'attaque, et un dispositif de protection (114) couplé au circuit d'attaque (108). Le dispositif de protection (104) comprend un commutateur de défaut (234) ayant une position qui maintient le courant de signal d'attaque à un niveau qui permet la poursuite du fonctionnement du moteur de lumière (102) pendant une condition de défaillance dans le dispositif d'éclairage ou en dessous de ce niveau.
