Abstract:
1. A device for electric power supply of a portable lamp, comprising an enclosure and electric connections for connection, in a power supply circuit, with either one, as required, of two interchangeable electric power sources that are a storage battery and a set of at least two primary cells, the electric connections comprising a contact for connecting a terminal of one of the primary cells to a terminal of the other primary cell, the enclosure delineating a housing for accommodating either the primary cells together or the storage battery, wherein said contact comprises a clamp deformable between a first configuration in which each one of two facing branches of this clamp is positioned to connect one of said terminals by penetrating into an accommodating volume for accommodating the storage battery, and a second configuration in which the two branches are placed outside said accommodating volume such that the accommodating volume is between the two branches, wherein, in the first configuration, a free end of each branch defines a terminal for connecting one of the primary cells, and wherein, in the second configuration, the two branches are configured to clamp the storage battery between them.
