Title of the invention: Lighting device, for example a table lamp, a suspended or wall-mounted light point, a luminous sign, etc.

[0001] The present invention relates to a lighting device. For example, the lighting device may be a table lamp, a suspended or wall-mounted light point, a luminous sign, etc.

[0002] In the catering and event catering sector, usual table lamps are powered by a built-in battery, which is recharged by gathering all the lamps in one place and connecting a cable or a small base specific to each lamp. If the restaurant has a small number of tables, this method is still acceptable, but for restaurants with a large number of tables, recharging so many lamps becomes an insurmountable problem.

[0003] Furthermore, gathering lamps in the same place is risky, it can result in a high probability of falling, and could require dozens of chargers to be able to recharge them all. In addition to these disadvantages, it must also be taken into account that the battery is the component of the product with the shortest lifespan, namely no more than 5 years based on daily recharging.

[0004] In this context, the present invention has the technical task of providing a lighting device which overcomes the above-mentioned drawbacks of the known technique.

[0005] In particular, the present invention aims to provide a lighting device which is versatile and practical to use.

[0020] Alternatively, the body 2 comprises a ferromagnetic part 6 and the power supply device 4 comprises a magnetic part 5.

[0021] As is known, the battery 4 comprises an electrical contact zone 7 for the body 2. Preferably, this zone is surrounded by the ferromagnetic part 6.

[0022] Preferably, the magnetic part 5 has an annular shape.

[0023] Preferably, the ferromagnetic part 6 has an annular shape.

[0024] Preferably, the ferromagnetic part 6 is metallic.

[0025] In this case, the magnetic coupling means constitute a crown system of magnets.

[0026] According to one embodiment, the body 2 comprises a compartment 8 which houses the power supply device 4. In particular, there is a part of the lighting device 1 which is adapted to house the power supply device 4.

[0027] Preferably, the body 2 comprises a stop surface 9 on which the feed device 4 is mounted. The surface 9 comprises the magnetic part 5. In particular, the surface 9 delimits the compartment 8 at the top.

[0028] Similarly, the surface 9 comprises a zone 7a of electrical contacts surrounded by the magnetic part 5. Preferably, the electrical contacts are of the elastic effect type.

[0029] In the preferred embodiment, the lighting device 1 is a lamp. In particular, it may be a table lamp or a lamp fixed to the ceiling or wall. In this case, the body 2 in turn comprises a base 3 intended to rest on a surface, for example a table. Everything said above for the body 2 in relation to the power supply device 4, must refer to the base 3.

[0030] In particular, the power supply device 4 is removably mounted relative to the base 3. Preferably, the magnetic part 5 is located on the base 3. Preferably, the base 3 comprises the compartment 8 and therefore the surface 9.

[0031] Preferably, the base 3 comprises a lower opening for access to the compartment 8.
