Incandescent bulb, has magnetic support on base to adapt bulb on screwed and magnetic bulb sockets, and base with ring between annular electrical and central contacts for insulation, where contacts correspond to that of screwed bulb socket

摘要

The bulb has a magnetic support (3) on a base (2) to adapt the bulb on a screwed bulb socket and a magnetic bulb socket by screwing and by magnetic attraction between the support and a permanent magnet of the magnetic bulb socket, respectively. The base has an insulating ring (4) placed between an annular electrical contact (V) and a central contact (5) for insulation. The contacts (V, 5) correspond to that of the screwed bulb socket.
