The present invention relates to lighting technology, in particular to lighting the circular lights with a spatial light signaling mainly in the upper hemisphere, such as the barrage of lighting fires, based semiconductor light-emitting diodes. Obstruction lighting lights are designed for spatial alarm, luminous markings as part of the aerodrome and orthodromic signaling complexes or svetoograzhdenie high-altitude and extended obstacles that may worsen the conditions of flight safety of aircraft and helicopters day and night in poor visibility conditions.

Lights are installed on high-rise and long buildings, industrial pipes, poles, transmission towers, etc., Blinker lights, red, amber or green can be used for marking helipads and runways of airfields, as navigation marks waterways, as well as signal lights, special vehicles, including in pulsed mode.

Known lighting device of the circular review [1], containing the building is Orme direct extended octagonal prism (octahedron) collected on lateral sides of the circumference of the light-emitting diodes.

The disadvantages of the devices due to the relatively low power of the light and a narrow radiation pattern in the vertical plane, providing the scattering angles less than 90o.

As a prototype of the selected lighting the fire [2], comprising a housing with installed on it combined with a protective glass cover and a cylindrical Fresnel lens, in which the horizontal planes in circles with two, three or more groups of light-emitting diodes with radially oriented optical axes collected on upright cylindrical ring holder.

The disadvantages of the prototype associated with poor lighting device settings due to the fact that the Fresnel lens does not provide a wide distribution of fire in the vertical plane (there is no radiation in the Zenith), which makes it impossible to observe it from all angles above the horizon. In addition, the device is complicated due to the use of a Fresnel lens and a combined protective glass cover.

The aim of the invention is to improve the lighting and thermal performance while simplifying e pie review comprising a housing with protective cap and set it on the holder, two, three, or more groups of light-emitting diodes connected to electrical power supply means, the said holder is made in the form of reinforcement collected it two, three or more hollow, right truncated pyramids with matching longitudinal axis of symmetry, on apodeme each of the side faces of which are mounted light emitting diodes with an optical axis perpendicular to these faces of the truncated pyramids.

This goal is achieved and the fact that each of the side faces of the hollow, right truncated pyramids perpendicular to the axis passing through located on the longitudinal axis of symmetry of fire single optical center and radiating center installed on it light-emitting diode. The technical result is also achieved by the fact that hollow, right truncated pyramids installed on the valve holder coaxially within the angle at the vertex of the bottom of the pyramid and side faces of each of them form channels between them for the passage of heated air.

To achieve the target also contributes to the fact that apogamy each of the side faces defined on nor is Imperii fire in the plane perpendicular to the specified axis relative to apothem each of the side faces of the other hollow truncated pyramid, within half-angle, which is the value 360o/n, where n is the number of faces the bottom of a hollow truncated pyramid.

The technical result is achieved by the fact that the lower hollow correctly truncated pyramid armature holder for a group of light-emitting diodes of fire involves the lower base ring, a mirror reflecting the radiation concave element having a profile of a parabola, the focal circle which coincides with the radiating centres of these diodes.

The outcome is strengthened by the fact that the outer surface of the side faces of each of the hollow, right truncated pyramid is covered with a mirror reflecting the radiation layer, for example, aluminum.

The objective is also achieved by the fact that hollow, right truncated pyramid is made in the form of shaped shell that is installed and curved on the edges of the truncated pyramid of the valve holder.

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

Fig. 4 - same as in Fig. 3, top view.

Fig. 5 - optical-signal fire (swing beams in the vertical plane).

It is shown in Fig. 1,2,3 and 4 lighting the fire of the circular review includes a housing 1, made of aluminum alloy or a suitable plastic, covered with optically transparent in the selected spectral region, for example in the visible spectral range, the protective cap 2 mounted in the frame 3 through a sealing o-ring 4 and held in place on the mandrel ring element 5.

The mandrel 3 with a protective cap 2 and the ring element 5 are fixed and sealed to the housing 1 through the seal 6 by means of hinge and tightening bolts.

Inside the protective cap 2 to the annular element 5 is assembled fittings removable holder 7 on which are mounted two (Fig. 1) three (Fig. 3) or more groups of light-emitting diodes, for example two groups of diodes 8 and 9. The valve holder 7 made in the form of shaped bracket, which has two (Fig. 1), three (Fig. 3) or more removable hollow, right truncated pyramids 10 and 11 with the same longitudinal axis of the octagon pyramid 10 (bottom of pyramid) and a removable hollow properly truncated tetrahedron 11 (top of pyramid).

On apodeme "ab" each of the side faces of the truncated pyramids 10 and 11 are mounted mainly on one, (but can be two, three or more) light-emitting diode 8 and 9 respectively to the optical axis O F' which is perpendicular to the mentioned side faces of the truncated pyramids. Each of these facets in turn perpendicular to the axis 00 (see Fig. 5) passing through located on the longitudinal axis ZZ' of symmetry fire a single optical center O and a radiating center F', F" and F"' installed on it light-emitting diode.

The upper truncated pyramid 11 can be installed on separate valves removable holder 12, providing replacement of the group of defective light-emitting diodes 9 during operation regardless of the group of diodes 8 installed on adjacent truncated pyramid 10.

Hollow, right truncated pyramids 10 and 11 with light-emitting diodes installed in repeating their shape around the perimeter of the nest of curly flanges 13 and 14 of the holders 7 and 12 respectively and mechanically fastened spring latches 15 and 16.

The upper hollow, right truncated pyramid 11 may be the mouth of the S="ptx2">

Hollow, right truncated pyramids 10 and 11 with light-emitting diodes installed on the valve holder coaxially within angleoat the top of bottom of the pyramid (shown dotted in Fig. 1) and side faces of each of them is oriented to the longitudinal axis of symmetry of the fire ZZ' (Fig. 1) angle1/2large angle o/2the side faces of the lower truncated pyramid 11. This side faces of the hollow, right truncated pyramids 10 and 11 form between them a channel 17 for the passage of heated air, i.e., to enhance convective heat transfer during operation of the fire.

Apogamy "ab' each of the side edges, mounted with light emitting diodes 8 and 9 (see Fig. and 2) or 18, 19 and 20 (see Fig. 3 and 4), at least one of the hollow truncated pyramids, for example 21, the offset around the longitudinal axis of symmetry of the fire ZZ' in the plane perpendicular to the specified axis (horizontal plane) relative to apothem each of the side faces of the other hollow truncated pyramid 22 and/or 23 within half-angle, which is the value 360o/n, where n is the number of faces of the lower hollow, right truncated pyramid.

In particular, in the fire, as shown in Fig. 3 and 4, apogamy side granpa 20o.

When used in the construction of fire light-emitting diodes with a wide cone beam scattering radiation component 60-120olower hollow, right truncated pyramid 23 (see Fig. 3 and 4) of the valve holder of these diodes 18 is advisable to match the lower base ring, a mirror reflecting the radiation concave element 24 having a profile portion of a parabola 25 (see Fig. 5), i.e., forming a paraboloid ring, the focal circle which coincides with luminous centers F' these light-emitting diodes 18 (Fig. 3 indicated by +). The arrows on all the drawings shows the rays emanating from the luminous centers of light-emitting diodes, the reflected rays from the ring element 24.

Hollow, right truncated pyramids 10 and 11 (Fig. 1) and 21, 22, 23 (Fig. 3) valve holders are made mainly of heat-conducting material such as aluminum or its alloys.

This helps to give them also a function of heatsink providing efficient conductive and convective heat exchange with the environment, which is important for cooling the power semiconductor light-emitting diodes.

Pets manufacturing of hollow sechennye pyramid can be made in the form of curved shells, with mechanically fixed ends 26 (see Fig. 4) installed and curved on the edges of the truncated pyramid 23 of the valve holder. In both cases, the outer surface of the side faces of each of the hollow, right truncated pyramid cover specularly reflective layer, for example, aluminum, reflecting the scattered radiation emanating from the walls of the protective cap 2.

Both versions of the device provide an electrical series-parallel connection of the chains (4 light-emitting diode for the variant shown in Fig. 1 and 2, and 6 diodes for the variant shown in Fig. 3 and 4) by the method of printed wiring on the panels of the flexible foil fiberglass (not shown) connected to electrical power supply means 27 to the transmitter 28 of the supply network.

As light-emitting diodes 8 and 9 can be used diodes series HPWL - VD HEWLETT PACKARD with scattering angle 20,5= 120owith radar current findings, or the high-power diode-type U-B OOOPS "OPTEL" (Russia) with wire pins. In all cases, the current leads are isolated on a bearing of truncated pyramids heat resistant wires with PTFE sheath and connect them to curved panels on current 220 V, 50-60 Hz or DC voltage 12-48 Century

The lights work as follows. When the power light-emitting diodes generate light beams, mainly conical configuration, which intersect (see Fig. 5) mainly on the "tails" of the curve of light distribution of each diode or overlap with offset, radiation filling the upper hemisphere (rays shown by arrows). When using the proposed circular lights as the barrage of lights is provided by the formation of a light distribution curve lights with high uniformity within from Zenith to 5obelow the horizon with the power of light is not less than 10 KD.

Using the ring, the mirror reflecting the radiation parabolic element 24 (Fig. 3 and 4) or 25 (Fig. 5) allows you to redistribute (arrows) part of the light flux from the lower hemisphere in the zone from 4 to 15 above the horizon, thus increasing the light power at the specified angles when using the previously mentioned light-emitting diodes up to 12-15 KD,

Installation of powerful light-emitting diodes 8 and 9 (Fig. 1 and 2) or 18, 19 and 20 (Fig. 3 and 4) in thermal contact with the flat faces of the hollow, right truncated pyramids 10, 11 and Neneh of heat-conducting material.

The location of truncated pyramids with the formation of channels 17 between their side faces increases the cooling efficiency due to convective teleperedach.

Thus, the optical characteristics of the signal lights is improved at the expense of fixed and properly distributed spatial orientation of the optical axes of light emitting diodes in the upper hemisphere, as well as in the design of a ring, a mirror reflective element and zirkulatornyi outer faces of the truncated pyramids.

Thermophysical parameters lights improved due to more efficient heat removal heat sources and light emitting diodes being in thermal contact with the valve holders and heat dissipation into the environment.

Along with this, the simplified design of fire resulting from the application as reinforcement holders light-emitting diodes hollow, right truncated pyramids and more simple protective cap, which provides the required spatial distribution of fire in the upper hemisphere.
