The known lamp with light-emitting diodes [1], containing equidistant from the longitudinal axis of the group of LEDs mounted radially on the same insulating disks with axial holes associated with the Central rod, and connected to current conducting elements of the standard cap.

The disadvantages of the lamp due to inappropriate configuration of the luminous body, isphere and in selected directions, what limits the use of lamps, for example, in lighting obstruction lights, airfield bidirectional lights and other lighting and light signalling devices.

The known lamp with light-emitting diodes [2], which provides the required light distribution in space, containing a Central core coaxial with installed hollow convex polyhedra, flat, oriented in predetermined directions of the faces of which are mounted the LEDs surrounding the specified terminal. At the free end of the Central rod placed electrical power supply means.

The disadvantages of the prototype due to the complexity of construction of polyhedra, for example, truncated pyramids with the required inclination of the faces of the functions of the plate-holders LEDs.

In addition, the lamp does not provide the spatial variation of the light distribution depending on operating conditions, for example, in bidirectional airfield lighting lights.

The aim of the invention is to remedy these shortcomings, the simplification of the structure, providing a spatial change of the light distribution that extends its functionality.

This objective is achieved in that in the waters, collected on the plates and connected to the means of power, these plates are made in the form of flat polygonal circuit Board, at least part of which is installed in the meridional planes intersecting the Central core, and at least in part oriented in the surrounding area of the sides (edges) of each polygonal circuit Board is mounted at least one led, the optical axis which is perpendicular to the specified direction (the edge), and the current-carrying pins are placed on the surface of the polygonal Board.

The task is achieved by the fact that the polygonal Board with LEDs installed on the hinge nodes collected at opposite ends of the Central rod, with the possibility of azimuthal angular rotation about the transverse axis of the lamp and secured in a predetermined position.

This goal is achieved and the fact that the lower part of the Central rod perpendicular him motionless with an additional adjoining polygonal cards available in the meridional planes that have been marked with an azimuthal angular position of the specified polygonal circuit Board and provided with a lock on it.

The objective is achieved by the fact that at least part of the polygonal circuit Board with LEDs mounted along the longitudinal axis of the Central rod parallel to each other.

The task also contributes to the fact that an additional fee is adjacent its bottom to the camera, which is equipped with means of power, for example, an electronic inverter mains supply.

The objective is also achieved due to the fact that the polygonal Board with LEDs and additional charges are enclosed in an optically transparent flask.

And finally, the achievement of the objective contributes to the fact that the camera with the electronic Converter mains associated with electrical power supply means, for example, with the international socle type E 27 or Gy 9,5.

The most preferred embodiment variants of the device according to the alleged invention shown in the drawings.

Fig.1 - lamp led, side view partly in section.

Fig.4 - same as in Fig.3, the bound is 1 and the surrounding LEDs 2, mounted on the plates, made in the form of a flat polygonal circuit Board 3. At least part of these 3 cards installed in the meridional planes intersecting the Central rod 1 (passing through the longitudinal axis of the lamp).

At least in part oriented in the surrounding area of the sides (edges) 4, 5 each polygonal circuit Board 3 is mounted at least one led 2. For example, for the barrage of lights with the desired maximum power of the light in the corners of +6to -6relative to the horizon in excess of 2-3 times the value of the light power of the flame generated in the Zenith, on the bottom side (edge) 5 each polygonal circuit Board 3 can be installed in 2-3 led 2, and these LEDs may have different angles of scattering radiation.

Collected on each flat polygonal Board 3 LEDs 2 are mounted so that their optical axes are perpendicular to the side (edge) 4 or 5 of each of these boards, while providing a desired orientation and obtaining a specified light distribution in the surrounding space by choosing the angle of inclination of the sides (edges) of each Board 3 and the choice of the led 2 with the desired angle russianjapanese requirements to the size and uniformity of light distribution. For LEDs with a scattering angle of radiation 20,5=30the number of polygonal circuit Board 3 should not be less than 12.

When mounting the LEDs 2 on the side edges 4 and 5 of the polygonal circuit Board 3 conductor conclusions 6 LEDs placed on the surface of these boards on one or both sides of each of them. Polygonal Board with 3 LEDs 2 can be installed on the hinge nodes 7, which is drawn in the Central rod 1 plates 8 and 9 with holes, in which are mechanically linked with the boards of 3 pins 10 and 11, providing the opportunity azimuthal angular rotation of each polygonal circuit Board 3 with respect to the transverse (zero) axis of the lamp OO’ locking them in a predetermined position.

On the lower part of the Central rod 1 perpendicular to it, we still have additional polygonal or round Board 12 adjacent to the lower sides of the meridional oriented polygonal circuit Board 3.

Additional Board 12, for example, in the form of a regular 12-gon has a marking 13 azimuthal angular position, including the null direction OO’ above the rotating polygonal circuit Board 3, and f which are stated mechanically attached to the circuit Board 3 elastic stoppers 15.

In one of the embodiments of the lamp along the perimeter of the extra Board 12 on the sides of the polygon can be mounted LEDs 16 with a radially oriented optical axes, conductor conclusions which are located on the surface of its bottom (back) side.

In Fig.3 and 4 show a second embodiment of the lamp light-emitting diodes, in which at least part of the flat polygonal circuit boards 17 and 18 with LEDs 2 mounted on hinges 19 (but possibly without them) oriented along the longitudinal axis of the Central rod 1 in parallel to each other. Two groups in parallel established between a polygonal circuit boards 17 and 18 are diametrically oriented at an additional flat Board 20, providing the concentration of light radiation in diametrically opposite directions. This lamp is effective when used in airfield bidirectional lights.

Mounted on each of the polygonal circuit Board 3, 17 and 18 LEDs 2 with conducting pins 6 interconnected in series, forming a chain, for example, by the method of the printed wiring via conductor tracks 21.

Chain of LEDs each polygonal circuit Board interconnected in series or is at with LEDs with each other and with the electronic Converter can be used mikrorayony, installed from the backside extra Board 12 (not shown).

Both versions include pairing the back (bottom) side of the additional card 12 or 20 with camera 22, which is equipped with means of power, for example, electronic Converter 23 mains supply.

The latter is connected to the mains (primary power source) electrical power supply means, in the form of conductive wires 24, or using international base E 27 or Gy 9,5 (POS. 25, Fig. 3).

Polygonal Board with LEDs and additional charges 12 can be enclosed in an optically transparent flask 26, which increases the degree of protection lamp from the external environment.

Lamp led operates as follows.

When connecting the mains supply electronic Converter generates a constant or pulsating voltage and current on the chain sequentially or in parallel, serially connected LEDs, which generate optical radiation of a selected wavelength range.

Thus a given distribution (the distribution of the forces of light in space is determined by the scattering angle of the selected LEDs, angles and number of installed in the lamp is, and azimuthal angular position of these cards on the riser, which is changed by the user by turning the circuit Board (as shown by the arrows in Fig.2, 4).

For the first versions of the device may change the light distribution of the lamp with the concentration of the luminous flux in azimuth at an angle scattering 270-300.

For the second variant of the device, the concentration of the luminous flux of the lamp in two diametrically opposite directions simultaneously (two-beam lamp) in angle scattering 20-40for each beam.
