FR2808624A1 - Light bulb/socket magnetic connection method having magnetic light bulb holder released with sideways swing without using force and allowing easy bulb replacement. - Google Patents

Abstract

The light bulb socket connection method has two magnets holding the light bulb in place. When release from the socket is wanted, the bulb can be swung sideways without applying any force. A new bulb can also easily be placed in position.

Description

 The present invention relates to a bulb and its socket remaining in electrical contact thanks to a magnetic field which assembles them (figurel).

This magnetic field is created by two magnetic rings (Figure 4).

It is difficult to separate two magnets sticking one against the other, also the process exposed in figure 2, shows us that the separation of the two magnets is facilitated by the inclination of the bulb in any direction.

This slight inclination caused by the user of this bulb makes it possible to effortlessly break the magnetic field, and to replace the used bulb with another.

As long as the magnetic field is not intentionally broken by the user, it is impossible for the bulb to leave its socket to which it is electrically connected.

This process allows a more practical use of the bulb, in comparison with bayonet or screw bulbs.

This invention makes it possible to hold the bulb in its support whatever the position of the bulb - vertical with the socket below - vertical with the socket above - horizontal perpendicular to a wall for example.

The ease and speed of handling is evident from the conventional bayonet or screw methods. The manipulation to replace a bulb is much faster than with screw bulbs that we have to screw or bayonet or we have to find the notches of the socket before applying great pressure to engage the bulb in the notches . In addition, the manipulation of these classic bulbs sometimes forces us to pass our hand through the orifice of a lampshade or a ceiling lamp or a spot, and to practice the manipulation of screwing or locking in bad conditions. .

The two magnetic rings are sheathed with a thin layer of plastic ensuring the integrity of the magnetic rings against impact or wear, avoiding for example the creation of magnetic parasitic particles.

The magnetic rings contain within them the necessary connections figure 3) to the passage of electricity in the bulb. The electrical contactors are themselves insulated from the magnetic rings (potential electrical conductors) by an insulating material (for example: plastic or ceramic).

The electrical connection is ensured regardless of how the bulb is placed.

The central connector is a simple rod always in contact once the bulb is in place with the central connection of the socket. The second peripheral contactor compared to the first is a ring ensuring a perfect connection to the ring contained in the bulb socket (Figure 5), it is therefore impossible to incorrectly connect the bulb to its electrical source.

Claims (3)

Claims 1) System of electrical connections of a bulb and its socket, characterized in that it comprises two magnets which maintain the connection. The separation of the socket and its bulb is effected by tilting in any direction of the bulb, allowing to break the magnetic field without effort, and to replace a new bulb with even less difficulty. 2) System according to claim 1 characterized in that the two potentially conductive magnets are sheathed with a thin plastic layer, guaranteeing them against impact and the formation of parasitic particles. 3) System according to claim 1 characterized in that the electrical connections are contained inside the magnetized rings and are isolated from the magnets by a plastic or ceramic material.
