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.Sources of information1.
