[0001] The lighting installation is a mobile means of illuminating areas and objects during emergency and rescue operations in peacetime and wartime - in cases of destruction of electrical power sources and electrical networks.

[0002] From the patent documentation published in patent databases, lighting installations are known (RU 2192581 C1, 10.11.2002. RU 49179U1, 10.11.2005. RU 2003148 C1, 15.11.1993. RU 57871 U1, 27.10.2006. WO 02095288 A, 28.11.2002. JP 9306210 A, 28.11.1997. US 5499941 A, 19.03.1996. US 6322230 A, 27.11.2001. RU 2344340 C2, 20.01.2009 - prototype).

[0003] The prototype description discloses a lighting installation comprising a support made of an inflatable shell with a rigid base mounted on the ground, a support pad, or a load-bearing element. Guy wires are located along the transverse perimeter of the support, connected to the ground and the support, and a light source connected to the support. The support base has an opening for supplying pressurized air to the support. The installation is equipped with a means for movably securing the support base to the ground, allowing the support base to rotate relative to the ground or to roll along the ground. Guy wires are used to rotate the support base relative to the ground.

[0004] The common features of the invention disclosed in the prototype and the invention presented in this description are the features characterizing lighting installations, each of which is intended for illuminating areas in distress at night, wherein each lighting installation contains a frame, a housing connected to the frame with the possibility of rotating it in a vertical plane relative to the frame, at least one lighting element electrically connected to a power source, a reflective element made of a fabric flexible inflatable shell, which is fixed to the housing, wherein the air blower is located in the cavity of the housing.

[0005] The prototype system has limited applicability due to the shape of the inflatable shell. Its operational reliability does not meet modern requirements due to the location of the lighting element (light source, lamp) in the upper portion of the shell, which is pressurized by the inflated air. If the air pressure in the shell drops, it collapses and collapses, damaging the lighting element. Furthermore, during nighttime rescue operations, as practice has shown, sophisticated lighting systems appropriate to the challenging conditions are required.

[0033] The lighting installation comprises a support frame 1 (Fig. 1), a housing 2 of the installation connected to the frame, which is connected to the frame so as to be rotatable in a vertical plane relative to the frame. An inflatable shell 5 is secured to the housing 2. The shell may have the shape of a cylinder, as shown in Fig. 1, or a spherical shape, as shown by way of example in Fig. 4.

[0034] Housing 2 of the installation contains blocks 3 of multiple lighting elements 4 (Fig. 4), electrically connected through an input in housing 2 to a power source (not shown). An internal combustion engine generator or a battery can be used as a power source.

[0035] Figure 5 shows four blocks 3, each made of a plurality of lighting elements 4. The installation may have several blocks consisting of a plurality of powerful light sources. In Figure 5, each block 3 contains approximately fifty lighting elements 4.

[0036] The lighting installation comprises multiple interchangeable inflatable shell variants, each of which (Figs. 8-19) is detachably connected to the installation's housing 2. All versions of the lighting installation comprise an inflatable shell made of a woven, flexible, sealed material that performs light-diffusing or light-reflecting functions, or both light-diffusing and light-reflecting functions, depending on the installation's intended purpose and operating conditions. The lower, open end of the shell is secured to housing 2 by a standardized fastening mechanism designed to connect shells of any shape and size to the lighting installation's housing.

[0037] To operate the installation as a floodlight with a directed light stream emanating from the shell, a transparent element 6 of the shell, covering the shell from above, can be used. The lighting installation can also be used as a floodlight in the case when the inflatable shell is removed from the housing 2 of the installation. An air blower 7 (Fig. 7) is connected to the housing 2 of the lighting installation into the cavity 11 of the inflatable shell, wherein the blower 7 is located in the cavity of the housing 2 and above it in the housing 2 four blocks 3 of lighting elements 4 (Figs. 4, 5, 7) are located. Blocks 3 of elements 4 are located and secured on the cooling part 8 of the installation (Fig. 6). The cooling part is a flat partition fixed in the housing 2 above the supercharger 7. The cooling part 8 (Fig. 6) has a plurality of heat-dissipating finned elements 9 for removing heat from the lighting elements 3 and this cooling part is located between the supercharger 7 and the blocks 3 of the lighting elements 4.

[0038] The cooling part 8 may also have a plurality of openings 10 for supplying cooling air through them from the blower into the cavity 11 (Fig. 1) of the inflatable shell when the installation is in working condition and the cavity 11 is filled with air under pressure from the operating air blower 7.

[0039] The housing 2 of the installation is detachably connected to the frame 1 and is mounted on horizontal axes 12 of the frame (Fig. 1, 3) with the possibility of rotating the housing 2 relative to the frame in a vertical plane, as well as fixing the housing in the working position with clamps 13 in the form of handles.

[0040] The supercharger 7 (Fig. 7, shown below) is a hollow casing, open at the top, in the bottom wall 14 of which a plurality of round air intake openings 15 are made, communicating the atmosphere with the cavity of the housing 2. In the supercharger casing there is a fan impeller (not shown), fixed on the shaft of an electric motor (not shown), which is connected to a power source.

[0041] The inflatable shells shown in Figs. 8-19 may be made of a light-diffusing material and function as a light diffuser. Alternatively, a reflective coating, shown in dotted lines in the drawings, may be sprayed onto the inner surface of the inflatable shell, or a portion of the shell may be made of a reflective material with a reflective surface, shown in dotted lines in the drawings, or the entire shell may be made of a reflective material, shown in dotted lines in the drawings.

[0042] The lighting system has a variety of inflatable shell options. Each option differs from the others in its design and the combination of reflective and light-diffusing inner surfaces of the inflatable shell. These surfaces can be made of different woven materials, or they can be composed of a single material, with or without a reflective layer on the inner surface. The woven material was chosen for its compact roll-up when not in use and ease of unrolling and inflating when in use. Woven materials do not preclude the use of other similar materials in the system's design.

[0043] Each inflatable shell variant has a standardized connection at its bottom to the installation body. This connection is preferably in the form of a circular flange 16 for connecting it to a mating flange 17 (Figs. 1-3) of the installation body 2. Flange 16 is universal and is used in all versions of the lighting installation's inflatable shell.

[0044] In the basic version, the inflatable shell 17, shown in Fig. 8, is made of a light-diffusing material, and the basic version of the shell and subsequent versions of the shell contain the aforementioned unified flange 16. The unification of the flange is that it ensures the docking of all shells of different diameters and shapes with the housing 1 of the installation.

[0045] The second embodiment (Fig. 9) shows an inflatable shell 18, the lower portion 19 of which has the shape of an inverted trapezoid in the longitudinal section of the shell, wherein the lower portion of the shell is made of a reflective material, and the upper portion 20 of the shell is made of a light-scattering material. The reflective surface 21 of the reflective material is shown by a dotted line, and this surface 21 in all embodiments of the inflatable shell is always located inside the shell.

[0046] There is a modification of the second variant (Fig. 10), which shows an inflatable shell 22 having a lower part 23 in the form of an inverted trapezoid, made of flexible reflective material with a reflective surface 21. The upper part 24 of the shell has a cylindrical shape, which is divided by a seam 25 into left and right cavities 26 and 27, respectively, wherein the right cavity 27 is made of reflective material, and the left cavity 26 is made of light-scattering material.

[0047] The third embodiment (Fig. 11) shows an inflatable shell 28 having a lower cylindrical portion 29 made of a reflective material with a reflective surface 21, and an upper portion 30 of the shell. The upper portion has the shape of an upside-down trapezoid and is made of a light-diffusing material. Moreover, in the upper portion 30 of the shell is located a conical, upside-down reflective element 31 with a reflective surface 21 directed outward.

[0048] There is a modification of the third variant (Fig. 12), which shows an inflatable shell 32, the lower part 33 of which has a cylindrical shape and is made of a reflective material with a reflective surface 21, and this modification also has an upper cylindrical part 34 of the shell, made of a light-scattering material, and in the upper part 34 of the shell there is a conical reflective element 31, inverted with its apex downwards, with a reflective surface 21 directed to the outside.

[0049] In the fourth variant (Fig. 13) an inflatable shell 35 is shown, the lower part 36 of which has the shape of an inverted trapezoid, the side and lower walls of the lower part are made of a reflective material with a reflective surface 21, and the upper part 37 of the shell has a conical shape tapering upwards, made of a light-scattering material, while the height H of the upper part 37 of the shell is within the range of H = (5-6) h, where h is the height of the lower part of the shell. There is a modification of the third variant (Fig. 14), which differs from the third variant in that the height H of the upper part of the shell is within the range of H = (1-3) h, where h is the height of the lower part of the shell.

[0050] The fifth embodiment (Fig. 15) shows an inflatable shell 38, the lower part 39 of which is made in the form of an inverted trapezoid, the side and lower walls of which are made of a reflective material with a reflective surface 21, and the upper part 40 of the shell has the shape of a hemisphere and is made of a light-scattering material. There is a modification of the fourth embodiment (Fig. 16), which differs from the fourth embodiment in that the height H1 of the upper part of the shell is within the range H1 = (1-3) h1, where h1 is the height of the lower part of the shell.

[0051] The sixth embodiment (Fig. 17) shows an inflatable shell 41, which has a spherical shape, made of a light-diffusing material. Moreover, the fifth embodiment of the shell has a modification - the shell is made in its lower part 42 (Fig. 18) from a light-diffusing material, and in the upper part 43 of the spherical shell it is made of a reflective material with a reflective surface 21. In another version of the fifth embodiment (Fig. 19), the lower part 42 of the shell is made of a reflective material with a reflective surface 21, and the upper part 43 of the shell is made of a light-diffusing material.

[0052] The variant of the inflatable shell shown in Fig. 10 has a vertical seam 25, and the variants of the inflatable shells shown in Figs. 9, 11-19 have horizontal seams 44 - connections of two woven fabrics of materials during the manufacture of the shells.

[0053] The lighting system operates as follows. Housing 2, which contains all of the aforementioned parts, is mounted on support frame 1. Flange 16 of the inflatable shell is placed on housing 1, and flange 16 of the shell is joined to flange 17 of the housing in a known manner, and the system is turned on. When the system is turned on, air blower 7 forces compressed air into cavity 11 of the shell, causing the inflatable shell to harden and essentially act as a pole for illuminating the area. Electric current is supplied to units 3 of lighting elements 4, illuminating the emergency area around the system.

[0054] When the installation is in operation, its lighting elements 4 and their blocks 3 heat up, while the cooling part 8 of the installation, located between the blower 7 and the blocks 3 of the lighting elements 4, removes heat from the lighting elements 3. Since the cooling part 8 is located between the blower 7 and the blocks 3 of the lighting elements 4 and the air blower 7 is located under it, the air flow coming from the blower fan flows around the cooling part 8 and removes heat from it.

[0055] In the event of a sudden shutdown of the installation, air is released from the inflatable shell into the atmosphere, the inflatable shell folds and the blocks 3 of the lighting elements 4 remain intact, protected by the folded inflatable shell and the body.

[0056] The lighting installation comprises multiple interchangeable inflatable shell variants, each of which (Figs. 8-19) is detachably connected to the installation's housing 2. All versions of the lighting installation comprise an inflatable shell made of a woven, flexible, sealed material that performs light-diffusing or light-reflecting functions, or both light-diffusing and light-reflecting functions, depending on the installation's intended purpose and operating conditions. The lower, open end of the shell is secured to housing 2 by a standardized fastening mechanism designed to connect shells of any shape and size to the lighting installation's housing.

[0057] To operate the installation as a floodlight with a directed beam of light emanating from the shell, the transparent shell element 6, covering the shell from above, can be used. The lighting installation can also be used as a floodlight when the inflatable shell is removed from the installation's body 2.

[0058] If necessary, the lighting installation, its body and inflatable shell can be rotated from a vertical position to a horizontal position and below the horizontal position, which ensures illumination of the space below the location of the frame 1 of the installation.

[0059] The first version of the inflatable shell (Fig. 8) for the lighting installation operates as follows. When air is injected into cavity 11 of shell 17, the shell straightens and assumes a cylindrical shape. Made of a light-diffusing material, the shell transmits light and disperses it evenly into the space, as the unified ring-shaped flange 16, under air pressure within the shell, forms a cylindrical shell, uniformly illuminating the space.

[0060] The second embodiment of an inflatable shell for a lighting installation (Fig. 9) operates as follows. When air is blown into cavity 11 of shell 18, the shell straightens and takes the shape of a cylinder having a diameter greater than that of the first embodiment of the shell. The shell, made of a light-diffusing material, transmits light and diffuses it uniformly into space, since the unified flange 16 in the form of a ring, under air pressure in the shell, forms the lower part 19 of the shell, connected to the upper cylindrical part 20 along an annular perimeter. Moreover, since the lower part 19 has the shape of an inverted trapezoid with a surface 21 reflecting light from the inside of the trapezoid, the light from light source 3 (Fig. 5) is reflected from surface 21 upward and to the sides, while the brightness of the space illuminated by such a shell is significantly increased without increasing the power of the light source. Modification of the second embodiment (Fig.10) operates similarly to the second variant shown in Fig. 9. When light hits reflective surface 21, it is reflected to the left, in the direction indicated by arrow A, increasing the illumination of the area to the left of the shell, while a shadow is formed on the right side of the shell. This illumination is related to the specific operating conditions of the lighting system, significantly expanding its functionality.

[0061] The third embodiment of the inflatable shell (Fig. 11) for the lighting installation operates as follows. Light from the light source 5 passes through the cavity of the lower portion 29 of the shell, is reflected by the reflective surface 21 of the lower cylindrical portion 29, the brightness of the light is amplified, then the light stream hits the reflective surface 21 of the conical reflective element 31, is reflected from it in different directions and exits outward in different directions and downwards, illuminating a large area. Such a shell is used when it is necessary to illuminate large areas. A modification of the third embodiment of the inflatable shell (Fig. 12) for the lighting installation operates similarly to the operation of the third embodiment, with the difference that the concentration of illumination in the upper portion of the shell around the conical element 31 is higher in comparison with the shell of the third embodiment shown in Fig. 11.

[0062] The fourth variant of the inflatable shell (Fig. 13) operates as follows. In the fourth variant, light is reflected from the reflective surface 21 of the lower part 36 of the shell and enters the upper part 37 of the shell, from where it is dissipated into the surrounding space, whereby at the end of the upper part of the shell the concentration of light escaping into space is greater than the concentration of light at the bottom of the upper part of the shell, and the wind loads on the shell, which has a conical shape tapering upward, are significantly reduced in comparison with the cylindrical shape of the shell. The specified parameters of the shell are regulated by the choice of the height of the upper part 37 of the shell within the limits in one case, when the height H of the upper part of the shell is within the limits H=(5-6)h, where h is the height of the lower part of the shell. In the other case (Fig. 14), when the height H of the upper part of the shell is within the limits H=(1-3)h, where h is the height of the lower part of the shell.

[0063] The fifth version of the inflatable shell for the lighting installation (Fig. 15) operates in a similar manner to the fourth version, and, unlike the fourth version, in the modification of the fifth version (Fig. 16), the light is reflected from the reflective surface 21 of the upper part 40 of the shell, from where it is dispersed into the surrounding space.

[0064] The sixth embodiment of the inflatable shell (Fig. 17) is used to illuminate small areas around the spherical shell 41, through which light passes and is evenly dispersed around it. If necessary, a modification of the shell (Fig. 18) is used, which does not transmit light upward, but reflects it downward by the reflective surface 21 of the upper part 43 of the shell, thereby increasing the illumination around the shell for the lighting installation. A modification of the sixth embodiment of the shell, which is shown in Fig. 19, makes it possible to increase the illumination of the space above the shell and reduce the illumination under the shell, even creating a shadow underneath it.

[0065] The replaceable inflatable shell variants described in this description significantly expand the functionality of the lighting system, allowing for the selection of appropriate lighting modes depending on the conditions of its use during the dark hours of the day in disaster-stricken areas. The technical result—improved reliability—is associated with effective illumination of emergency sites and the elimination of the possibility of damage to the lighting elements in the event of sudden disconnection of the inflator within the inflatable shell and its collapse into a non-operating position.
