The present invention relates to lighting, in particular for light sources - optical blocks or lamps on the semiconductor light-emitting diodes generating optical radiation of the red, green, yellow, blue, infrared or white light.
These lamps are designed for use in light signalling devices, such as obstruction lights, explosion-proof lamps, lighting, sutomatic, lights light marking airfields and heliports.
The known lamp (1) on the LEDs containing equidistant from the longitudinal axis of the group of LEDs assembled on the holder in the form of a convex polyhedron that consists of a combination coaxially installed multi-faceted rings with grooves, the walls of which are made at an angle equal to the angle contained therein conclusions LEDs.
Disadvantages of analogue due to the design complexity, increased dimensions, efficiency applications mainly in the layout with powerful LEDs that require efficient heat removal due to conductive heat transfer.
A known light source light-emitting diodes, applied in the signal optical device (2), made in the form of a flat circuit Board with soldered on the terminals of the LEDs arranged on concentric circles (nodes polar coordinate grid) or at the vertices and the centers of the polygons. To commit a specified position along the optical axis of the device, the LEDs were placed in the holes of the metal mask made of heat-conducting material.
The proposed effective light source for use in traffic lights, where the LEDs are mounted perpendicular to the Board, and their optical axes parallel to each other.
Thus, the disadvantages of the prototype associated with the difficulties of accurate spatial Orientali and fixing the position of the LEDs have different angles of inclination of their optical axes to a flat Board.
This makes it difficult to obtain a uniform light distribution of the light source in the hemisphere, which is important, for example, when creating a barrage of lights or lighting devices.
The aim of the invention is to improve the lighting and thermal parameters, increasing the uniformity of light distribution while simplifying the structure of the lamp on the LEDs.
This objective is achieved in that the light emitting diodes containing the charge on which the soldered terminals of the LEDs, at least portions of which are located in the nodes of a polar coordinate grid or on the sides and in the top right polygonal grid and the inverter mains supply and the circuit Board holder with means for electrical power supply, the findings at least part of the LEDs is curved in longitudinal planes passing through the longitudinal axis of symmetry of the lamp under the selected angles ranging from 0 to 90° corresponding to the direction of the optical axis of each led, and mechanically fixed on the Board with the selected spatial the orientation.
The objective is achieved by the fact that the curved terminals of the LEDs are mechanically fixed on the circuit Board electrically insulating compound, preferably ceramic-polymer heat-conductive dielectric compound.
The problem is solved also by the fact that on the circuit Board along the lines of a polar coordinate grid is made concentric projections on the walls of a conical shape with a triangular profile, forming installed and join them curved terminals of the LEDs.
Finally, to achieve goals and contribute something on the back side of the insulating Board mounted electronic components of the inverter mains electrical power supply with the means.
Preferred variants of the device according to the invention shown in the drawings.

Figure 4. Same as figure 3, top view.
Shown in figures 1 and 2 lamp led has a flat circular printed circuit Board 1 on which the soldered pins 2 LEDs 3. The LEDs 3 with the optical axis O-O, O 1 , O 3 and O 4 are installed in the nodes of the polar coordinate grid (shown by the dotted line, see figure 2). Conclusions 2 LEDs (except the installed LEDs on the axis O-O) is curved in the meridional planes (radial dotted lines)passing through the longitudinal axis of symmetry of the lamp O-O under the selected angles ranging from 0 to 90° . For their part, emerging from the body of each led 3, is oriented parallel to and comply with the directions of the optical axes of About 1 , About 2 , About 3 and About 4 of each of them.
In addition, curved conclusions 2 LEDs 3 is mechanically fixed on the printed circuit Board 1 with the selected spatial orientation of the optical axis by means of electrical insulating compound 4 and held in it by the specified compound and solder ends 5 on the back side of the Board.
For mechanical fixation of the pins 2 on the Board, it is preferable to use ceramic-polymer heat-conductive dielectric compound having a high adhesion to him and conductivity, improving thermal parameters of the lamp.
The angles of inclination of the optical axis O-O, O 1 , O 2 , O 3 and O 4 to the horizon for LEDs with scattering angle 2Θ 0.5 of the maximum light intensity within 5-7 KD is chosen equal to 90° , 45° , 65° , 85 and 0° respectively, which provides the spatial distribution of light intensity in the upper hemisphere with the increased power of the light in the corners -6° +6° . This distribution is regulated for obstruction lighting of circular lights.
On the back side of the printed circuit Board 3 with the electronic elements of the inverter 6 mains protected by the holder 7 Board, with electrical power supply means 8. The holder 7 is mounted on the bracket 9 for fastening the lamp in the light fixture.
The holder 7 can be paired with international standard socket E 27 or Gy 9,5 (not shown).
The second option lamp on the LEDs (see figure 3 and 4) provides for the implementation of the Board 10 with elevation soldered the LEDs 3, i.e. in such a way that along the lines of the grid are made of concentric protrusions 11 with the walls 12 of conical shape with a triangular profile.
By forming the protrusions 11 of the conical shape is installed and connected thereto curved conclusions 13 LEDs. Thus, the desired inclination of the optical axes of the LEDs is set by the angle of inclination of the generatrix of the conical surface of each protrusion 11, which is installed facing out of the case each led 3 conclusions 13, curved near the mounting holes in the circuit Board 10.
Conclusions 13 on the relief surface of the Board 10 cover mounting varnish or insulating compound, providing mechanical fixation.
This version of the card increases the accuracy of the installation and the required orientation of the LEDs in space.
The installation Board 10 on the doer 7, the pair with the Converter supply line and means mounting the lamp in the light fixture similar to that described above for the first variant.
Board 1 and 10 can be made in the form of regular polygons, the number of parties which corresponds to the number of LEDs 3 mounted on the periphery from the optical axis O 4 (not shown).
In this case, the LEDs are placed on the sides and at the top right polygonal grid.
The advantages of the proposed design of a flat lamp for emitting diodes are to improve the lighting settings by improving the uniformity of light distribution while simplifying construction and Assembly technology lamp.
In addition, improved thermophysical parameters of the lamp by contact heat transfer conclusions and buildings LEDs with heat conducting compound and the card.
