Detailed description and examples of carrying out the invention. With a detailed description of the method and device (Figs. 1-5), it is not advisable to dwell on their technological and design features known from published sources, and only their essential distinguishing features should be characterized in more detail. To achieve the specified technical result, a method for creating a shadowless light flux is proposed, according to which from individual luminaires-modules, the number of which is selected in the amount of nl, in relation to their total number If n is within (1 + l / n) <(nl + n) / n <2 and, rigidly fastening them, they form a modular lighting system from them. The system formed in this way is oriented towards the use of the light flux created by it in total with light fluxes that are secondarily reflected from the ceiling and walls of the room illuminated.

In each luminaire-module, the number of LEDs in the range from 10 to 10 ⁵ pieces is selected, installed on LED strips, selected in an amount from 1 to 10 ³ , and connected to the power supply unit. The LED strips are mounted on symmetric planar multidirectional reflective surfaces in an amount of 1 to 120. In this case, the angles of inclination to the horizon of symmetrical planar multidirectional reflective surfaces are selected between 5 ° - 85 ° to the horizon line.

By the totality of the installed LEDs, they create an adequate set of light beams, control the radiation intensity and combine to direct the light beams at an angle of total internal reflection to a structurally interconnected set of rectilinear and curved surfaces of the nodes of the lamp module. Formed by a combination of light beams, the light flux is scattered in the room space using its natural reflective surfaces, for example, the ceiling and walls, and restricting its propagation in undesirable directions. In this way, they ensure the two-sided impact of light on horizontal and inclined ceiling surfaces, as well as vertical and inclined wall surfaces. This is added to the main reflected from the nodes of the luminaire-module to the streams of light reflected secondarily from the ceiling and walls of the illuminated room and as a result form shadowless lighting of the necessary zones with its unevenness not exceeding 30% of its maximum value. When hit on the rough surface of the ceiling and walls, the light is reflected from them not under the condition "the angle of incidence is equal to the angle of reflection", but according to the "cosine law", i.e. diffusely in all directions, as a result of which shadowless lighting is additionally formed.

 In FIG. 2 schematically illustrates the principle of the formation of a luminous flux in a closed (four walls) or half-closed (two walls, for example, corridor) room using the natural environmental conditions of the environment, which provides for the use of the interaction of luminaires-modules and reflective surfaces such as ceiling and walls. Separate beams of light, denoted by vectors 16, emanating from light sources - LEDs 7, form in their entirety a luminous flux propagated in a room while passing through one, two and three times reflection, namely: once through ceiling; twice - through the ceiling and the wall (or vice versa); three times - through the reflective surface 2, the ceiling and the wall.

To achieve the indicated technical result, a modular lighting system is also proposed for implementing the method of creating a shadowless luminous flux, formed from individual luminaires-modules, the number of which is selected in the amount of nl, in relation to their total number n within (1 + l / n) <(nl + n) / n <2, rigidly fastened together by docking nodes. Moreover, each lamp module is made of an extended shape (Fig. 1 a, b) and is composed of a semi-cylindrical housing 1 made of extruded aluminum profile with which two symmetric curved reflective surfaces 2 are rigidly bonded.

 With the indicated curved surfaces, two oppositely directed flat surfaces 3, 4 are installed rigidly with angles a and β of their inclination, selected between 5 ° - 85 °, to the horizon line and the opposite direction from the vertical axis of symmetry of the lamp - module 5. In this case, one end of the profiled section of the housing of the lamp-module of a semi-cylindrical shape 1 and symmetrical curved reflective surfaces 2 are rigidly connected to the end of the surface 3 at an angle “a” within 5 ° <a <85 ° to the line horizon 19 and the other the end of the profiled section of the housing of the lamp-module of a semicylindrical shape 1 and symmetric curved reflective surfaces 2 are rigidly connected to the end of the surface 3 at an angle “β” within 5 ° <β <85 ° to the horizon line 19. The values of the angles a and β can be the same or different.

Omnidirectional flat surfaces 3, 4 serve as the basis for mounting LED strips 6 on them with LEDs 7 located on them. At the junction of the curved surfaces with the body, two symmetrically arranged pauses 8 are made, which serve as guide rails for the docking nodes 9 and circuit board 10 of the electric power supply 1 1, placed in the internal cavity of the housing 12. Thus, the symmetrically located grooves 8 on the inner side of the housing of the lamp-module of a semicylindrical shape 1 can simultaneously solve two design problems: they serve as slides for the circuit board 10, allowing regardless of the configuration of the mounting points of various power supply units 1 1 serve as a support for a rigid fastening; serve as slides for docking nodes 9 when assembling luminaires-modules in the lighting system. In the lower part of the inner cavity of the casing there is an electric cable 13 connected to LED lines of electric wires 14 passing through the technological hole of the casing 15 and flat surfaces, made along the entire length of the lamp-module, which allows mounting fixtures 17 luminaire-module to horizontal and inclined ceiling surfaces to the docking nodes 9 and (or) mounting plates 10.

Technological hole 15 allows you to simultaneously solve several design problems: reduces the cost of production of housing elements of the lamp module extrusion or injection method; serves as a stop for mounting the lamp-module (suspension, support, etc.); serves as a stop for docking nodes 9; serves as an opening for supplying electrical wires, cable leads; serves as a stop for fasteners 17. The fasteners of the lamp module are made with a fixed length or height-adjustable. In FIG. 3-4 illustrate some examples of the formation of luminaires-modules in lighting systems of two structural types: a structure with a beginning and an end; closed construction. The type and variability of modular lighting systems make it possible to solve various lighting tasks for lighting rooms, due to aesthetic, design and other preferences, in order to match and harmonize in the environment.

 The modular lighting system for implementing the method of creating a shadowless light flux can be constructed, in particular, (Fig. 3,4) in the form of an open rectilinear shape (Fig. 3a), an open sinuous shape with rounded (Fig. 3b) and ( or) with acute angles (Fig. Sv), an open spiral shape (Fig. Zg) with rounded and (or) acute angles, a closed regular (Fig. 4a, b) and (or) irregular polygonal shape (Fig. .4c) composed, for example, of polygonal and rectilinear sections. The docking nodes 9 (Fig. 5) of the system can be made in forms repeating the bend or the joint angle of adjacent fixtures-modules with the exception of the permissibility of the presence of a groove to reduce the visibility and visibility of the joints.

In FIG. 5 illustrates some variants of the shapes of the docking nodes 9, in particular, of a rectangular shape (FIG. 5 a), obtuse-shaped (FIG. 5 b), acute-angled shape (FIG. 5 c). The shapes of the docking nodes 9 are selected depending, for example, on the feasibility of a technological solution to the following design tasks: the need for rigid fastening of individual modules lei fixtures into an integral system of a given strength; minimization of the visibility and visibility of the joints at the point of view of the organic visual perception of the system as a whole and in the case of using the lighting system as an element of the room decor, and in cases of maximum masking of the lighting system, depending on the design tasks being solved.

 It should be noted that the principle of the unity of the invention is observed in the application, since the proposed method for creating a shadowless luminous flux and a modular lighting system for its implementation have the same purpose, serve the same purpose, together with each other, achieve the same technical result, as well as interconnected by a single inventive concept, characterized by the claims. At the same time, the concept of legal protection is based on the fact that the continuity and interconnectedness of the proposed objects, as well as the permissible variation in the implementation of certain essential features or their combinations predetermine, including the unconventional nature of the formulations of some features. For example, the design features of the luminaire are reflected not only by the characteristics of the nodes included in it and their structural interconnections, but also, in particular, with the help of, in particular, the angles “a” and “β” of the inclination of the multidirectional flat surfaces 3, 4 to the horizon line 19.

Thus, as follows from the foregoing, the features indicated in the claims are significant and purposefully interconnected with the formation of their stability. a healthy population, necessary and sufficient to obtain the specified technical result. The achieved technical result, as shown by the experimental data, can only be realized by an interconnected set of all the essential features of the claimed objects reflected in the claims, with any values covered by the claimed pulls and satisfying the declared features. The claimed significant distinguishing features were obtained on the basis of creative processing of the results of research and experiments, analysis and summarization of them and known from published data sources, interconnected with the conditions for achieving the technical result indicated in the application, as well as using inventive intuition.

 Industrial Applicability and Achievement

The proposed method for creating a shadowless luminous flux and a modular lighting system for its implementation do not contain features that cannot be realized using known technologies and devices. Compliance with the criterion of “industrial applicability” of the proposed facilities is also proved by the absence in the claimed claims of any features that are practically difficult to realize on an industrial scale. To concretize the design features of the developed lamp module, it is advisable to note that it has a rigid fastening of the housing of the lamp module half-cylindrical shape 1, symmetric curved reflecting surface 2, two symmetrical flat oppositely directed surfaces 3, 4 can be formed by stamping or extrusion from a monolithic billet in a single technological process.

 Among the other advantages of the described luminaire module and the modular lighting system formed by their combination that implements the claimed method, the relatively low cost of their manufacture and attractive ergonomic indicators can be noted. At the same time, the system formed from luminaires-modules has a single power input, having in its design a hidden cable channel, which increases the level of energy security of the system.
