The invention relates to lighting, particularly led lights with a given spatial distribution of the light used in airfield lighting lights (circular review, lens and others), for svetoograzhdenie high-altitude and extended objects. The lights are also installed on high-rise buildings, industrial pipes, masts and many other high-rise structures.

Lights of red, yellow, green, and blue colors can be used on Railways, water ways, on different types of vehicles. The mode of operation of the lights can be pulsed or continuous.

Known lighting device [1], consisting of a body and a cylindrical Fresnel lens, which is located inside a hollow plastic right octagonal prism. In the middle of each face of the prism posted by led. Eight LEDs make up the circle to create the demonstrates the flow of LEDs in a narrow region.

The drawbacks are a small force of light, due to only one row of LEDs, the lack of radiation in the upper hemisphere, which is required for many lighting devices, and weak heat from the LEDs, as they are mounted on a plastic prism.

Known selected as a prototype lighting the fire [2] containing the metal housing with locking pin and protective cap, the LEDs connected to the means of power and installed on the sides of one, two or more hollow polyhedra in the form of truncated pyramids, the mating between the bases. To improve heat dissipation from the LEDs inside a pyramid set their holder in the form of a massive centralnorthern-heat sink being in thermal contact with the housing and the pyramids.

The disadvantages of the prototype are those which are installed on the sides of hollow pyramids LEDs do not provide power radiation in some directions of space and, in particular, in the Zenith and close to it are fragile, and also in the lower hemisphere, because the faces of the pyramids may not be parallel to the vertical or horizontal planes. Their inclination to the vertical axis of the pyramid matters more is how the tilt of the faces of the different truncated pyramids differ from each other, and can have any value.

The aim of the invention is to improve light and spatial characteristics, the creation of powerful radiation in the right direction and simplify the design led to the fire.

This objective is achieved in that in the led heat, comprising a housing with a mandrel and a transparent protective or lens element holder LEDs are located on the sides of the external surface and the convex bases of the hollow polyhedron means of heat from the LEDs and the device of their power, the holder of the LEDs is made of the joint Assembly right hollow prisms, right hollow truncated pyramids and pyramids, inverted 180with a common axial line, and the point of intersection of the ribs of at least one base of each Assembly element located in the space on the part of the imaginary surface of the second order, forming a geometric body, selected, for example, from the group of a rotational ellipsoid, one-sheet hyperboloid, a barrel with a generatrix in the form of an arc of a parabola and/or circular arc.

The objective is achieved by the fact that the led in the fire the point of intersection of the ribs of the hollow prism and a hollow truncated pyramids derately, three or more bodies selected from the group listed above, as well as cylinders and spheres.

This goal contributes to the fact that the General centerline of the Assembly of hollow prisms and truncated pyramids inclined to the horizontal plane at an angle in the range from zero to 90.

The technical result is achieved by the fact that the surface of the polyhedron that is not occupied by the LEDs, with openings connecting the internal volume external to the polyhedron space inside the transparent protective element.

In addition, this goal is achieved and the fact that the holder of the LEDs is made of a circular set of ornate metal bands or rings, bent on transverse lines, the ends of which are fixed on the basis of a convex hollow polyhedron in such a way that they form a joint Assembly right hollow prize and the right hollow truncated pyramids.

In Fig. 1-3 show led light circular, comprising a housing 1, made of aluminum alloy or plastic optically transparent cap 2 installed in the mandrel 3 by sealing a sealing layer 4 held the hood 2 and the ring element 5 is fixed and sealed to the housing 1. Inside the transparent cap 2 on the annular element 5 is assembled fittings removable holders 7 and 12 with LEDs 8, 9, 10 and 11 of truncated pyramids 14, 15 and 17 and the prism 16. They all have a common vertical axial line ZZ’ (19). pyramid 15 inverted 180in relation to the pyramids, 14 and 17. In Fig. 1 the point of intersection of the ribs of the prism 16 and truncated pyramids 15 and 17 are in the space on the part of the imaginary surface of the second order, forming a one-sheet hyperboloid, and pyramid 14 and 15 is flattened ellipsoid of rotation. Figure 13 indicated shaped flange. The LEDs are located in space at the same time the imaginary surfaces of the second order of two bodies: one-sheet hyperboloid and ellipsoid of rotation.

Common axial line 19 ZZ’ Assembly of hollow prisms and truncated pyramids inclined to the horizontal plane at an angle of 90(Fig. 1, 2, 4). Thanks to the pads 18 located between the elements of the Assembly, there are openings, connecting the internal volume external to the polyhedra space inside the transparent cap 2.

In Fig. 3 shows the structure of an led of fire, which the centerline 21 of the Assembly of hollow prisms and truncated pyramids, lying on the Chennai pyramids lie on the imaginary surface of the barrel with a generatrix in the form of an arc of a parabola (and/or circular arc).

Hallmark led flame shown in Fig. 4, is that the point of intersection of the ribs only one base truncated pyramids lie on an imaginary spherical surface which merges into a cylindrical. This allows much more varied design features led fire at a certain limit holder LEDs spherical (22) and cylindrical (16) surfaces.

In Fig. 5 depicts a fairly narrow metal strip 23, is bent on transverse lines. The circular set of curved stripes on the outer side of which is placed the LEDs, going to the optical block, the cross section of which is shown in Fig. 6. The Central cylinder 24, which is designed for cooling (heat from the LEDs 25, attached to the top 26 and bottom 27 metal bases by means of screws 28. Bent on transverse lines of metal strips 29 and 30 are fastened together with the bases 26 and 27 by the screws 31 and 32. The electrical connection of the LEDs to each other carried by wires 33 and 34, the ends of which are out of the optical block.

In Fig. 7 and 8 shows the design of the led of fire that can be attached to the vertical is provided in the portion of the surface curve of the second order 37 (in part of the surface of the spheroid of rotation or barrel forming a circle or a parabola). It is created by curly bent along the transverse direction of the metal strips 38 and 39 are placed relative to each other at a right angle.

In Fig. 9 shows a removable cylindrical shell 40 with soldered ends of electrical leads 41 LEDs 42. The shell is characterized by flexibility and can be attached to the Central rod by any known means. The shell may also have a conical shape.

The work of these designs led fire is as follows. After switching on the AC or DC led lights, which provide radiation in a given region of space. Since the diagram of distribution of light intensity of each led is known, it is easy to calculate the total radiation Assembly such LEDs and create a design that meets the given requirements.
