The invention relates to the light engineering, in particular to the lamps, built on the basis of a combination of gas-discharge lamps and led emitters with a powerful LEDs. Fixtures are intended for illumination of open spaces, roads, railway, courtyards, etc. Successfully lamps can be used for growing plants in commercial greenhouses or in private greenhouses, when irradiated production areas to increase the productivity of livestock and poultry. Despite high efficiency high power led white light they can successfully replace powerful sodium discharge lamps of high pressure /NLD/ and metal halide /IPF/ for the above-mentioned applications, mainly because of the difficulties of solving the heat problem when linking a large number of powerful /1-3 W/ LEDs in lighting fixture lamps acceptable sizes comparable to the size of lamps with discharge lamps. In addition, light fixtures with NLD and IPF Philips, Osram pursuant /1/ higher light output of lamps with power LEDs on 50% and 20% respectively. In turn, these gas-discharge lamps with comparable to modern LEDs light output, high power, relatively compact luminous body and lower cost per 1 LM light flux are of unsatisfactory quality of light /spectral composition of radiation for the above applications. In particular, for exterior lighting fixtures with NLD, for example, highways, squares along with normal brightness level you want spectral composition of radiation close to the curve of bednosti eyes and the same perception of light in the conditions of the night and twilight vision, when the led lighting is more efficient /2/. To use these NLD production lamps with high output radiation in red-orange spectrum is clearly not enough light flux in blue and green region of the spectrum to optimize spectral efficiency of photosynthesis /3/. Becomes a prospective task of creating a combined /hybrid/ lamp that take advantage of high intensity discharge lamps and led emitters deprived of their individual weaknesses. Known combined spotlight /4/, which is used to illuminate remote objects of military equipment in the visible and IR range of spectrum that contains korotkogo gas-discharge lamp luminous body which is in focus paraboloid reflector, and led block the nozzle mounted in "blind" hole spotlight, with powerful light-emitting diodes, optical axes are parallel to the focal axis of the reflector. Ring led block the nozzle can be also installed along the perimeter of the reflector. Spotlight forms a narrow beams of radiation /1-8 deg./, making it difficult to use it for lighting of open areas or in crop production. Famous lamp /5/ for lighting of open areas with sodium discharge lamps of a high pressure, installed in the long MAGNETOM the reflector with the outlet, covered by a protective glass and a cover with the materials collected in it start-up and power supply equipment. Similar lamp-feed, for example JSP 80-600 01545, THE 16-545-435-2007, is used in crop production. The drawbacks of lamps are associated with poor spectral composition of radiation used for discharge lamps, as discussed above. Known modular lamp /6/ on the powerful LEDs for lighting of open areas and highways, made in the form of three led emitters extended matrix /modules/ with a powerful LEDs, each of which are collected on the radiator cooling, connected to the lighting fixture. Known also led the irradiator /7/ for crop containing long rectangular case with side reflectors and defined therein line cards with LEDs connected to the power source emitting in blue and red spectral regions with optical axis oriented towards the outlet of the irradiator. The shortcomings described in /6 and 7/ fixtures due to the need for a significant increase of its dimensions /in 4-4,5 times due to the necessity of application of a large number of LEDs to provide the required achievable lamps with discharge lamps high intensity radiation. For cooling the above led matrices and arrays fixtures it is necessary to use bulky radiators cooling on the basis of aluminum alloys, which together determine the high cost of products. The aim of the invention is to create a combined lamp with optimized spectral composition of radiation with improved weight and dimensions and heat settings and advanced features. This goal is achieved by the combined lamp containing lighting fittings with gas-discharge lamp, mainly sodium lamp, high pressure, installed in the main focal plane concave reflector, high-power LEDs and gear and supply equipment for them, to lateral walls of the specified concave reflector adjacent collected in thermal contact on the radiators of cooling the led emitters, made in the form of led matrices, lines or modules with powerful LEDs optical axes, oriented in parallel or at an acute angle to the main focal plane concave reflector, emitting in the selected spectral ranges, supplementing the radiation intensity discharge lamps and change total spectral composition of radiation lamp. The goal is achieved and what led emitters with matrices, rulers or modules with powerful led and cooling radiators insulated from the side walls concave reflector with discharge lamps, for example, an air gap. The problem is solved and that led emitters based on a power led articulated connected to the lighting fixture with a concave reflector with the possibility to change the angle of the optical axes of these led to the main focal plane concave reflector with gas-discharge lamp. The goal is strengthened by the fact that each led emitter is made in the form of a cascade of longitudinally oriented relative to the concave reflector steps of heat conducting material, forming the radiator conductive heat sink for the collected on them in thermal contact lines or modules with power LEDs, parallel to the main focal plane concave reflector. The problem is solved and that led emitters made with powerful LEDs blue, blue and/or white radiation with a color temperature range 5000-6500 To complement radiation sodium lamps of high pressure in the band spectral sensitivity of the human eye for night and twilight vision, predominantly in the range of wavelengths range from 400 to 600 nm. The aim is achieved by the fact that the led emitters made with powerful led's blue, blue, green, red and orange radiation in the selected combinations depending on the type of gas-discharge lamps, supplementing radiation specified lamp in the band spectral efficiency of photosynthesis /400-700 nm/. The goal is promoted also by that radiation sodium lamps of high pressure in red-orange spectrum integrated with the radiation of blue and green range of the spectrum of high-power LEDs with a ratio of 6:3:1, respectively. The solution also contributes to the implementation of the lighting fittings-protected camera, coupled with the front or rear portion concave reflector with gathered in her electronic start-control devices for gas-discharge lamps, combined with dual power source, connected to an led emitters.

Led matrix 7 and 8 with a powerful LEDs installed in thermal contact on radiators 11 and 12 with cooling fins, each of which is made in the same case, for example, by extrusion of aluminium alloy, covered by a protective glass or diffuser. Section led emitters 5 and 6 with radiators cooling 11 and 12 insulated from the side walls of reflector 3 discharge lamp mainly air gaps 13 and 14, but can be separated from them insulating pads /not shown/. This mechanical attachment of the buildings of the led emitters 5 and 6 with concave reflector 3 in the lighting fixture 1 lamp is made with the joints of 15 and 16 and brackets 17, also delivering the ability to change from 0 to 30 degrees angle optical axes 00 LEDs 9 and 10 emitters to the main focal plane ZZ reflector with gas-discharge lamp, thereby driving the light distribution of the luminaire and its spectral composition of radiation by mixing light fluxes.

However, a secure Luggage 24 for the supply of equipment lamp and led emitters can be installed in the lighting fixture on the back concave reflector /see figure 3/ with the execution on it rotatable carrier Lira 25 combined lamp. The second variant of the combined lamp, the cross section of which is shown in figure 3, contains two identical led emitter 26 and 27 of the output holes, covered with a protective glass or optical elements, each of which is made in the form of a cascade of longitudinally oriented relative to the extended concave reflector 3 steps 28 of heat conducting material, forming radiators conductive heat sink for installed on them in thermal contact led modules 29 or modules with powerful LEDs 30.
