A lighting device (10) which includes a body (16,18) with at least two contacts (22,24,26), an energy storage device (42) which is connected to the contacts (24,26) and which stores electrical energy when the contacts (24,26) are connected to an electrical power source, a first light source (80), and a switch arrangement (52) which is responsive to disconnection of the power source from the contacts and which then switches to connect the first light source to the energy storage device.
La présente invention concerne un dispositif d'éclairage comportant un corps avec au moins deux contacts, un dispositif de stockage d'énergie qui est connecté aux contacts et qui assure le stockage d'énergie électrique lorsque les contacts sont connectés à une source d'énergie électrique, une première source lumineuse, et un agencement de commutateur qui est sensible à la déconnexion de la source d'énergie des contacts et qui ensuite commute pour connecter la première source lumineuse au dispositif de stockage d'énergie.
