Description

The invention relates to the field of lighting, in particular to a pendant lighting system that can be used to illuminate living rooms, premises, individual items of exposition at exhibitions and in shop windows.

A known lighting system (US 2002064979 A1, H01R 25/00, 05/30/2002), consisting of a busbar trunking, connectors mounted on the busbar, mounting brackets of the lighting unit on the connector and fixtures. In this case, the busbar trunking includes a busbar frame with a longitudinal channel, inside which upper and lower guide channels are formed, in which the conductors are placed. The connector is inserted into the busbar, moves along the guide channels and interacts with the conductors. Copper conductors are used to transfer electricity from the busbar to the fixtures.

A disadvantage of the known system is its complex design, a small contact surface between the conductors and the contacts of the connector, which when moving the lamp along the busbar can lead to rupture of the electrical contact, in addition, the busbar material does not allow for bending.

A known lighting system (US 6244733 B1, F21V 21/35, 06/12/2001), consisting of a suspension, including end support elements mounted on the side walls of the room, a disk mounted on the ceiling, a support pipe in which the cables of the power supply unit are laid, consisting of wires connected to the supply contacts of the busbar trunking, and fixtures, while the busbar trunking consists of aluminum conductors interconnected by a plastic insulator insert, and the lamp contains a housing, a mounting mechanism and a lamp holder, while utri housing contacts are arranged, which interact with the busbar conductors.

The known system has drawbacks in that the lighting system has a complex structure, is difficult to install, has a large number of interacting elements that provide power to the suspension unit, busbar and lamps, in addition to the known lighting system there is no possibility of creating a multi-level lighting system and therefore, the ability to change the light composition.

The technical result consists in simplifying the design of a suspended multi-level lighting system, in facilitating the installation of the lighting system and connecting the busbar conductors to a power source and providing the ability to quickly change the light composition without changing the design of the lighting system.

The claimed technical solution is achieved due to the fact that the lighting system consists of a suspension unit that provides a rigid connection of the lighting system to the ceiling of at least one connector connected to the suspension and busbar, a power supply unit containing at least one power wire the busbar and at least one lamp mounted on the busbar with the possibility of movement, while the power supply unit consists of a clamping element with power contacts and a clamp screw, providing which fixes the clamping element and clamps the supply contacts to the busbar conductors, the connector is multilevel for connecting several busbars located at different levels to the electric power transmission and provides the possibility of mechanical rotation by 360 degrees, the busbar consists of 2 C-shaped brass conductors, interconnected by a plastic insulator insert.

Further, the claimed lighting system is illustrated by drawings.

In FIG. 1 shows a suspension assembly.

In FIG. 2 shows a rotary mechanical multi-level connector.

In FIG. 3 shows a diagram of the power supply to the busbar.

In FIG. 4 shows a busbar trunking.

In FIG. 5 shows a lamp with a first mounting device.

In FIG. 6 shows a lamp with a second mounting device.

The lighting system consists of a set of elements, namely a suspension unit, connectors, a power supply unit, busbars and fixtures.

The suspension unit (Fig. 1) contains a sleeve (1), on the external surface of which a thread is made, a hollow tube (2) of the suspension, on the internal surface of which a thread is made, and a decorative plug (3). To install the suspension, the sleeve (1) is fixed to the ceiling (4) and closed with a decorative plug (3). The sleeve is fastened with a fixing screw (5), which is also closed with a decorative washer (6). The suspension tube (2) is screwed onto the threaded sleeve (1). This design allows you to rigidly hang fixtures and has a minimum size.

A rotary mechanical multi-level connector (7) is attached to the free end of the suspension tube (2) (Fig. 2), to which at least one busbar (8) is connected. Moreover, the connector is multilevel for connecting several busbars (8, 9) located at different levels of the lighting system with the transmission of electricity. To transfer electricity between busbars, the connector contains boards with concentric paths and pin, spring-loaded current collectors (not shown in the figure). In this case, the connector (7) is made with the possibility of mechanical rotation by 360 degrees, providing the ability to rotate one busbar (8) of a multi-level lighting system relative to another (9), without interrupting the transmission of electricity between them.

To power the lighting system, a 42V power supply is used, which allows you to synchronously change the lighting intensity of all lamps. The power supply (Fig. 3) from the power supply to the busbar conductors (8) is provided by a power wire (10) surrounded by a dielectric sheath. The power wire (10) is connected to the power contacts (11) of the clamping element (12), which is connected to the busbar. The connection (fixing) of the clamping element (12) with the creation of the necessary clamp of the supply contacts (11) to the busbar conductors (8) is provided by the clamp screw (13). Tightening the clamp screw (13) provides reliable rigid fixation of the power supply unit on the busbar (8). At the same time, loosening the clamp screw (13) makes it possible to remove the power supply unit from the busbar.

The busbar (8) (Fig. 4) consists of 2 C-shaped brass conductors (14), interconnected by a movable plastic insulator insert (15). Busbar performs decorative, supporting and conductive functions. The execution of conductors (14) with C-shaped brass increases the ductility of the busbar, which allows bending the busbar without excessive internal stresses to small radii, without violating the conductive functions of the busbar. In addition, the execution of conductors (14) C-shaped increases the contact area of the conductors (14) with the supply contacts (11) of the power supply node and the supply contacts of the contact node of the fixtures, which ensures uninterrupted power supply of lighting elements (fixtures).

After mounting the busbars, the fixtures (15) are installed (Fig. 5, 6). Lamps (15) contain a housing (16), a contact node (17) for interacting with busbar conductors (14) (8), a fixture for mounting the lamp on the busbar and a light source. The luminaire (15) is inserted into the busbar (8) from below, for which a longitudinal groove is made in the upper part of the luminaire housing (16), and is fixed from above by the mounting device. The fastening device can be made in the form of a mechanical dielectric fixing screw (18) (Fig. 5), which is screwed into the upper part of the lamp housing (16), or using a magnetic fixing plug (19), which is installed in the upper part of the housing (16) lamp (Fig. 6). Both fastening devices provide reliable fixation of the luminaire (15) with the possibility of sliding movement along the busbar (8) and the necessary clamping of the supply contacts of the contact node (17) of the lamp to the conductors (14) of the busbar (8) to ensure constant uninterrupted power supply to the lamp (14). To move the lamps (15) of the multi-level lighting system from one level to another, the fixing screw (18) is unscrewed or the fixing plug (19) is removed, the lamp (15) is removed from the busbar (8) and installed on the busbar (9) of another level. In this case, the power to the lamp (15) is supplied immediately after fixing the lamp with a screw (18) or a plug (19). As a light source, LED lamas, incandescent lamps, fluorescent lamps, etc. can be used.

Thus, this design allows you to create a multi-level lighting system that ensures uninterrupted operation of lighting elements and allows you to quickly and without changing the design of the lighting system to change light compositions, due to the possibility of moving the lamps along the busbar, the easy movement of the lamps between the busbars and the rotation of the busbars relative to each other.
