The disadvantages of the prototype caused by poor configuration of the luminous body of the lamp, which does not ensure the redistribution of the light flux along the axis and eliminates the possibility of obtaining a uniform light distribution in the hemisphere. This makes it impossible for effective coordination lamp with elements of reflective and refractive optics.

This goal is achieved and the fact that the hollow convex polyhedron is made in the form of a set of paired between the bases of the hollow correctly truncated pyramids, inscribed in the curve of the surface of the ball zone.

The task is achieved by the fact that one of the reasons is inscribed in a ball belt upper right of the truncated pyramid is made in the form of a flat Board with the attached light-emitting diodes, the optical axis which perpendicularly his base ball zone mechanically fastened on the leg with current-carrying elements of the lamp base.

The outcome also contributes to the fact that hollow convex polyhedron is made detachable, comprising of coaxially installed hollow polyhedral rings provided on each face at least one end-to-end rectangular groove mating with the base adjacent adjacent polyhedral ring, the walls of the groove is made at an angle equal to the angle specified therein for the electrical outlets light-emitting diodes, the optical axis which is perpendicular to the respective faces of polyhedral rings.

To achieve the target contributes to the fact that the ends of the electrical terminals of the group of light-emitting diodes soldered in parallel installed inside the hollow convex polyhedron flat rings of different diameters, connected to the current conducting elements of the lamp base.

This goal is achieved and the fact that the holder of the light-emitting diodes made in the form of a truncated plane perpendicular to the longitudinal axis of the lamp, hollow polyhedra from the group of a dodecahedron or icosahedron inscribed in a part of the world, with installations and dodecahedron mechanically fastened to the leg with current-carrying elements of the lamp base.

On each side face 8 and the faces 5 of the hollow polyhedron 3 installed in thermal contact with the faces of one or more light-emitting diodes 1 and 2, respectively, with the optical axes, for example, OO1O2F2O3F3(see Fig. 7) perpendicular to the respective faces, and optical is the center O of the lamp.

Hollow convex polyhedron 3 made in the form of a set of paired between the bases 9 of the hollow correctly truncated pyramids 10, 11, 12 and 13, inscribed in the curve of the surface of the ball above the waist.

On the upper base correctly truncated pyramid 13, combined with a ground ball belt, which is a flat fee of 5, light-emitting diodes 2 are installed equidistant from the longitudinal axis zz' concentric circles with the optical axis perpendicular to the specified Board. In the center of the Board 5 has a light-emitting diode, the optical axis which passes through the light center O of the lamp.

The bottom base is properly truncated pyramid 10, coinciding with the base of the ball zone, mechanically secured to the side legs 7 with the base 14 of the lamp, in particular with the international socket type Gy 9,5.

Represented correctly truncated pyramids 10-13 hollow convex polyhedron 3 are split along the lines of 15 passing through the centers of the faces 8, i.e., a collection of coaxially installed hollow polyhedral rings (two rings form one extreme pyramid 10 or 13, or two pyramids 11 and 12, as shown in Sich, the EMA multi-faceted rings are made through the rectangular groove 17, mating with the base adjacent adjacent polyhedral rings.

The walls of the groove 17 is made at an angle equal to the angle contained therein electrical terminals 18 (see Fig. 2) light-emitting diodes, the optical axis which is perpendicular to the respective faces of polyhedral rings and coincide with the specified angle of conclusions.

The ends of electrical leads 18 groups of light-emitting diodes placed on the edges 8 of each of the truncated pyramids 10-13 soldered in parallel installed inside the hollow convex polyhedron 3 flat ring 19 (see Fig. 2 and 3) of different diameters depending on the size of hollow truncated pyramids along the lines of 15 connector and their parts.

Ring 19 provided with projections 20 (see Fig. 3) for mounting in grooves made in the walls of the truncated pyramids (not shown) on lines 15 connector and their parts.

On the rings 19 are made of current conducting paths 21 that connects the findings of each group of light-emitting diodes among themselves and with conducting elements 22 flat panel 23. The latter is mounted on the side wall of the leg 7 and is connected to the base 14 of the lamp.

The Central hole 24 of the ring 19 is installed (nanimously diodes are moving prijemnom contact with conducting elements 22 flat panel 23. On the rings 19 may also be mounted ballast resistance and other elements of the Converter circuit (not shown), which can be used to power the lamp from the industrial network.

An integral part of the pyramids 10-13, ring 19 and the flat Board 5, together installed on the side of the leg 7 of the lamp, tighten and mechanically fixed thereto by screws 24a.

In Fig. 4, 5 and 6 shows a second variant of the lamp light-emitting diodes, in which the holder is made in the form of a hollow polyhedra representing the icosahedron 25 inscribed in a portion of the ball 26 (shown dashed), truncated by a plane base 27 which is mechanically fixed to the tubular leg 28.

In the center of each face 29 of the icosahedron is made round holes, which are a tight fit in thermal contact with the faces of the installed light-emitting diodes 30 and insulated electrical pins 31 (see Fig. 5), for example chetyrehkantnye diodes firm LLC SPC "OPTEL" (Russia) type U-266, in which the heat sink is carried out mainly from the side walls of the housing.

Holder in the form of a truncated icosahedron 25 is made integral, for example, by bold lines 32 of the heat-conducting of effective heat dissipation from the light emitting diodes 30.

Each face 29 of the icosahedron perpendicular direct emanating from a single light center of the lamp, which coincides with the center of the ball 26 and the optical axis of all light-emitting diodes 30 are perpendicular to these faces and coincide with the specified direct.

The ends of the electrical terminals 31 groups of light-emitting diodes 30 soldered by the method of printed wiring on the coaxially installed inside the hollow convex polyhedron, in particular inside the icosahedron 25, bent into the cylinders shells 33 (see Fig. 5 and 6) of different diameters. The live tracks on the shell 33 is connected with the current-carrying elements mounted inside the tubular holder 28 (not shown) to the standard base 34 of the lamp, such as a base type E14 or E27.

Another variant of the lamp light-emitting diodes (see Fig. 8) provides for the manufacture of the holder in the form of a hollow polyhedra representing inscribed in the part of the world dodecahedron 35, truncated by a plane base 36 which is mechanically secured to the leg 37 of the lamp with the international socket 38 type Pk 30 d, mainly used in lamps for airfield lighting of the lights.

Each pentagonal faces 39 of the dodecahedron establish the m faces 39. Thus the optical axis of each disposable in the centre faces the light-emitting diode 41 passes through the light center of the lamp (not shown).

Electrical leads of the light emitting diodes 40 and 41 connected to the base 38 of the lamp, similarly to that shown for the first (see Fig. 2 and 3) or the second (see Fig. 5 and 6) variants of the lamp.

Holder in the shape of a dodecahedron 35 is made detachable by a bold line 42.

Described versions of the lamps light-emitting diodes function as with series connection of diodes and parallel-series connected chain of diodes with a ballast resistor (resistance can be soldered inside the holder) directly to the DC power source or inverter industrial network (not shown).

When the diodes 1, 2, 30, 40 and 41 generate a luminous flux of red, green, yellow, blue, or mixed colors in the surrounding space with a relatively smooth distribution of light power. The uniformity of light distribution is determined by the scattering angle of the selected light-emitting diodes, the density of their placement on the carrier and type of the selected holder.

First the projector type, involves the application of light-emitting diodes with a relatively small angle scattering (2 0,5= 4 - 30o).

The second and third options lamps to light emitting diodes (Fig. 4 and 8) provide for the use of light-emitting diodes with larger scattering angles (20,5= 40 - 120o).

Location on the same face 5 (Fig. 1) or 39 (Fig. 8) increased number of light-emitting diodes can significantly increase the strength of the light bulb in the direction of the optical axis of the Central diode passing through the light center of the lamp (see Fig. 7), which becomes important when using light-emitting diodes with wide scattering angles.

The optical scheme (Fig. 7) is shown by arrows angle scattering of light emitting diodes 40 and 41 (20,5= 80o) installed on two adjacent faces 39 of the dodecahedron 35. The intersection of the arrows illustrates the intersection of the extreme rays in the angle of scattering, i.e., overlapping light distribution curves as diodes, positioned on one face, and diodes located on adjacent faces. The optical axis F1O1F2O2F3O3same face and same axis F'1O'1, F'2O'2, F'3O'3smev O1F1and O'1F'1pass through the light center of the lamp O.

The proposed design options lamps light-emitting diodes significantly enhance their capability to obtain an almost circular light distribution.

Lighting the lamp parameters improved at the expense of the precise orientation of the optical axes of the diodes in space and enhance the uniformity of light distribution, and also due to the opportunity of increasing the strength of the light in the desired directions.

Thermal parameters of lamps is improved by providing a thermal contact of each led housing with a holder on a plane or on a lateral surface while using holders as the cooling radiator.
