  In Figure 7 we see a light wall 1 consists of several parallelepiped elements. The base of this wall 1 consists of a main element 2 and a secondary element 3.

  By "main element", in the present description and in the claims, is meant an element consisting of a base B situated in an XOY plane and at least one straight generatrix G lying in a plane XOZ or YOZ in an orthogonal representation. , the base B and the generator G forming a volume V. The main element comprises an electrical connection 4 with the external electrical network. According to an essential characteristic of the present invention only the main element 2 of the modular lamp comprises a connection to the external electrical network. This connection 4 is secure, as will be seen later in the description.

  "External electrical network" means the utility grid that provides 240 V or 110 V electrical power. "Secondary element" means an element consisting of a base B located in a plane XOY and at least one rectilinear generatrix G lying in a plane XOZ or YOZ in an orthogonal representation, the base B and the generator G forming a volume V. According to one characteristic of the present invention, this secondary element 3 has no connection to the electrical network. external.

  The main element 2 and the secondary element 3 comprise electrical connection means and possibly mechanical connection means which make it possible to electrically and / or mechanically connect at least one main element 2 with at least one secondary element 3 or at least one secondary element 3 with at least one other secondary element 3 ,,.

  According to the present invention can be connected any number of secondary elements 31, 32, 33, ... 3r, between them so that they are electrically and / or mechanically connected. Thus, the user can connect the desired number of elements together to form a desired light wall of desired height and length.

  As will be seen in the following description, the electrical connection means may also constitute mechanical connection means and even mechanical locking means of the elements relative to each other.

  In Figures 1A to 1E, there are shown various possible forms of the base B. However, these are examples that are in no way limiting.

  The base can be square or rectangular (BI), hexagonal (B2), triangular (B3), parallelepipedic (B4) or trapezoidal (B5). FIG. 2 shows an example of assembly assembly with bases BI, B2, B4, B4. But the user can perform any assembly of his choice. Thus, it will be enough for him to acquire modular elements and to assemble them to create luminous walls of any volume. To allow a joined assembly between the various elements, it suffices to choose elements whose generator G has the same inclination with respect to the plane XOY. According to the invention, the base may also be circular, the elements will then be cylindrical and may be assembled along the generatrix G. Such an assembly will also form a light wall.

  Figures 4 to 7, there is shown elements according to a first embodiment of the invention. These elements are of basic square B, and they comprise four generators G1, G2, G3 and G4 or heights which thus form four faces FI, F2, F3 and F4.

  By generatrix G is meant in the present description and in the claims, a line forming an angle with the base B (thus with the plane XOY in which is the base B); this generator is the generatrix of a cylinder when the base is circular and when the base has at least three sides, each angle formed by two sides comprises a generator. In the case of a triangular base, the element comprises three generators or heights, in the case of a hexagon, the element has 6 generators or heights defining 6 faces.

  In Figure 8 there is shown another embodiment of an element according to the present invention. The secondary element 3 is parallelepiped and has a main element 2 inside the secondary element 3, said main element 2 having an electrical connection 4 with the external electrical network. The lateral faces 7, 8, 9, 10, the lower face 11 and the upper face 12 of the parallelepiped are made of a rigid sheet. This rigid sheet may be paper, stiffened fabric, plastic, metal, glass, etc. Inside there is a bulb 13 placed in a base 14. To prevent the melting or the deterioration of the lateral faces 7, 8, 9, 10, openings 6 may be provided and / or an opening 5 can be provided in the upper face. . Finally, it may be possible to provide a mesh portion 15 in a side face to allow aeration and avoid melting or deterioration of the faces.

  There is shown in the figure a common light bulb that emits light in the visible. However one can provide any type of lamp emitting in any wavelength range, such as infrared or ultraviolet. The light source may be a diode, a light filament, etc. Figures 9 to 14 show another embodiment of the present invention.

  In the figures, it has been shown in more detail the electrical connection means. The main element (FIG. 140) comprises an electrical connection means 16 with the external network. The main element 2 also comprises electrical connection means with one or more secondary elements. According to an essential characteristic of the invention, the lamp comprises means of electrical connection between the main element and at least one secondary element and between at least two secondary elements which allow an electrical connection in the horizontal direction, but also in the direction vertical. The connection means with the secondary elements may also constitute means for positioning the secondary elements and also mechanical securing means.

  For this purpose, the electrical connection means consist of ball joints 17 which receive at least two tubes, a horizontal tube 18 and a vertical tube 19. These tubes 18, 19 contain electrical wires which connect a plug 20 (FIGS. , 12) and a socket 21 located respectively at each end of the tube 18 (or 19). The vertical tube 19 supports elastic hooks 22, 23 which enclose an ampoule, for example a xenon bulb, 24.

  Depending on the bulb used and the materials used for the faces of the main and secondary elements, it may be necessary for the sake of safety to use a low voltage current. It is then possible to provide a transformer 25 (FIG. 12) disposed inside the main element 2. The following transformers may be used, for example, and without limitation: Type Voltage Power Remarks (V) (W) Ferromagnetic 230 to 13.2 105 Toroidal thermal protection Fuse circuit breaker Ferromagnetic 230 to 13.2 105 Non-thermal thermal protection Fuse circuit breaker Converter 230 to 13.2 10 60 or electronic 20 -105 Ferromagnetic 230 to 24 105 Thermal protection (25,2) circuit breaker Fuse Converter 230 to 24 10 60 or electronic (25,2) 20 105 According to the more preferred embodiments shown in Figures 4 to 14, the modular lamp consists of: - a main element 2 forming a base for - a secondary element 3, a secondary element 3.1 and possibly secondary elements 3.2, ... 3.5.
