Korchagina, 8, kv. This invention relates to lighting technology and in particular to lighting fixtures using a hollow, slotted light guide for illuminating an interior of a structure with pneumatic supporting parts.

The furniture of the present invention can be used to illuminate workshops, halls, exhibitions, sports and concert halls, theaters, public buildings as well as all types of auxiliary structures and spaces, e.g. warehouses with inflatable (pneumatic) supporting parts whose shape is maintained by atmospheric pressure.

There are already known lighting systems for interior lighting. In such systems, the desired level of illumination is achieved by using individual fixtures, wall fixtures or fixed fixtures or floor lamps. There are also known systems for interior lighting that ensure uniform reflected illumination with the aid of floodlights or large light sources.

All known lighting systems are known from the considerable weight of the lighting fixtures. The use of such systems in fully pumped structures is dangerous, as they may drop 2 61 340 as the air pressure drops in the supporting parts. In addition, conventional lighting systems make it necessary to install electrical wiring in fully pumpable profitable parts. The efficiency of reflected light lighting systems is limited by the effect of a low luminous flux utilization factor. An increase in the efficiency of such a lighting system requires a high coefficient of reflection on the inner surfaces of the fully pumped supporting parts. However, if this requirement is met, the use of natural light will remain virtually impossible, as it will require a high transmittance in the shell of the fully pumped structure.

A lighting arrangement is further known which includes a hollow cylindrical light guide with a slot, which may have various cross-sectional shapes, including circular and elliptical. The light flux emitted by the light sources is concentrated by means of optical input devices and is directed through a window to a light guide with a hollow slot. The part of the inner surface of the light guide in question is provided with a light-reflecting coating which is applied to the inner surface in question using e.g. vacuum aluminisation. This light flux is reflected several times from the light reflecting coating on the inner surface of this slotted light guide and enters the interior to be illuminated through a light transmissive slit in a light diffusing or transparent material, this slit extending in the lower portion of the shell over the entire hollow slit. The shape of this hollow slot light guide is maintained with the aid of rigid type moldings, in addition to which inlet valves are also installed to supply air under overpressure to the hollow light guide, as well as outlet valves to let out air heated by light sources.

However, in order to be able to hang the lighting fixture in question by suspension, special communication cables (wires, wires, etc.) or a rigid and sturdy bracket for this hollow slotted light guide must be used, which equipment and brackets require a lot of space.

The present invention mainly seeks to provide lighting fixtures for illuminating the interiors of structures having pneumatic supporting parts, in which structure the light guide is supported without the use of any special mechanical fasteners.

The above and other objects of the present invention are realized by providing a luminaire structure for interior lighting of structures with pneumatic supports, the apparatus including a light guide with a hollow slit with a sheath of flexible film, a portion of the inner surface of this sheath with a light-reflecting coating. along its entire length while that part of this envelope facing the interior to be illuminated is a light-transmitting gap, at least one optical input device with at least one light source mounted on at least one end of a light guide with a hollow slot and optically connected to this hollow slot light directing the light source into the light flux into the hollow slit light guide, and parts for supplying gas to the hollow slit light guide through at least one inlet valve mounted on the main in the housing of a light guide with a hollow slit. This luminaire structure is characterized in that the light guide with the hollow slot is also a supporting and shaping part of the structure provided with pneumatic supporting parts and replaces at least a part of said pneumatic supporting parts.

It is preferred that the light guide with the hollow slot is attached to the shell of the structure by an annular towing part.

It is most preferred that the ends of at least three hollow slit light guides in a curvilinear shape come together at a given point while the opposite ends of these hollow slit light guides are optically coupled to a corresponding optical input device.

It is desirable that the light guide with the hollow slot and the shell of the structure form a single entity.

The light-transmitting gap in the side surface of the hollow-slit light guide may be made of a material of the structure shell, in which case said light-transmitting gap must be hermetically connected to the part of the hollow-slit light guide having a light-reflecting coating.

It is also nice that the hollow slit light guide has at least one bend and that a mirror is installed in each of these bends so that the light flux spreads evenly along the entire length of the hollow slot light guide.

The present invention simplifies the assembly of lighting fixtures as well as the installation of an electrical circuit, simplifies the design of the structure when using pneumatic supporting parts and ensures safety in cases where a gas pressure drop occurs in the supporting parts of the structure. The invention makes it possible to omit the hanging and supporting of light guides with hollow slits, bearing in mind that such hanging and supporting requires a solid and rigid base. The present invention reduces the amount of heat input from light sources into the interior of the structure and provides a double centralized means of releasing excess heat from the interior.

Referring now to the accompanying drawings, the proposed construction for interior lighting of a structure with pneumatic supporting parts includes a light guide 1 with a hollow slot (Fig. 1) with a sheath 1 '. Part of the inner surface in this sheath 1 'is provided with a light-reflecting coating 2 having a high reflection coefficient.

61 340 5

The sheath 1 'is a flexible film, one part of which facing the interior 3 to be illuminated is a light-transmitting gap 4 made of a light-transmitting film. The ends 5 of the light guide with a hollow slot rest on optical input devices 6, which may be, for example, floodlights, car headlights or special optical input devices of the type of this group. The shape of the light guide 1 with a hollow slot is maintained by the effect of the prevailing gas, e.g. air overpressure, which is developed with the aid of a compressor 7. The gas is directed to the hollow light guide 1 via a branched air slot 8 and inlet valves 9. The light guides 1 with a hollow slot are attached to the sheath 10 of the structure 11. This sheath 10 is a light-transmitting polyethylene tetraphthalate film, which makes it possible to use natural light during the day.

Figure 2 is an enlarged view of the ends 5 optically connected to an optical input device 6 having a light source inside, e.g. a metallic halogen discharge lamp.

From the supply source 12, the light flux is directed through a window 13 made of a transparent, heat-tolerant material into a light guide 1 with a hollow slot. The direction of the light flux is shown in the figure by arrows 14.

Fig. 3 is a view of a hemispherical structure 11 in which the light guides 1 with hollow slits in the meridian direction also act as supporting and shaping parts. One of the ends 5 in each hollow slit light guide 1 is optically connected to the optical input device 6 while the opposite ends of these hollow slit light guides come together at point 15. The above arrangement of hollow slit light guides ensures rigidity of the entire structure 11 even without the sheath 10 , in this case it is unnecessary to connect the sheath 10 to the hollow, slotted light guides 1 so that the sheath 10 may simply be stretched over said light guides 1. A minimum of three hollow light guides 1 with slots must be used to guarantee the rigidity of the structure of Fig. 3.

Fig. 4 is a cross-sectional view of a hollow slotted light guide 1 connected to a sheath 10. That portion of the sheath 1 'in a hollow slotted light guide 1 provided with a light reflecting coating is connected to the sheath 10 by an adhesive tape 16.

According to Figure 5, the sheath 10 is integral with the light guide 1 with the hollow slot, which is realized by ultrasonic welding of this sheath 10 to this light reflecting coating 2 or by gluing the sheath 10 along the seam 17. The embodiment of Figure 5 adds structure 11 (Figure 1) rigidity.

According to Fig. 6, the part 1 'of the sheath of the hollow, slotted light guide 1 provided with the light reflecting coating 2 is connected to the outer surface of the sheath 10 of the structure 11 (Fig. 1) by welding or attaching the flanges 18 (Fig. 6) to the sheath 10.

A light-transmitting slit 3, which is a light-transmitting flexible film, is hermetically connected to the part of the sheath 1 'where there is a light-reflecting coating, and this slit 3 is from the sheath 10 of the structure 11.

According to Fig. 7, the light guide 1 with a hollow slot is inside the structure 11 (Fig. 1) and is connected to the sheath 10 (Fig. 7) by welding or gluing the ribs 18 of the light guide 1 with the hollow slot attached to the sheath 10.

Fig. 8 is a view of a V-shaped structure 11. The light guides 1 provided with a hollow slot, which support the structure 11, are provided with a single bending angle of magnitude o? In this case, it is necessary that both ends 5 of the hollow slit light guide 1 are optically connected to the optical input devices 6 so that the light flux passes through the entire hollow slit light guide 1. The stability of the light guides 1 with a hollow slot in the V-shaped structure 11 can only be guaranteed by attaching these light guides 1 to the housing 10.

Fig. 9 shows a structure 11 having the shape of an upside-down U. A hollow, slotted light guide 1 has two bending angles oC and β, which may be equal or different from each other.

The optical input devices 6 are separated from the light guides 1 by light components 13 (Fig. 2) and placed in recesses 19 (Fig. 9) which are made in the floor of the space 3 and as a result the optical input devices 6 are protected from mechanical stresses.

In order to guarantee the passage of light flux through the corners and β, mirrors 20 are provided, as a result of which the optical input device 6 can be placed only at one end 5 with a hollow, slotted light guide 1.

Mounted on the surface of the hollow, slotted light guide 1 is an outlet valve 21, which is intended to reduce the air pressure inside the hollow, slotted light guide 1.

61 340 7

The principle of operation of the proposed luminaire for illuminating the interior of structures with pneumatic supporting parts is based on the propagation of light flux (compare arrows 14) due to multiple reflections from the light reflecting coating 2 (Fig. 10). as a result, the light flux passes along the hollow, slotted light guide 1 and part of it (compare arrows 14) enters the interior 3 through the light-transmitting slit 4, which is illuminated. When the optical input device 6 is located at one end 5 of the light guide 1 (Fig. 9), the ratio between the largest size and length of the latter cross section is 20-50. The light-transmitting slit 4 of the hollow light guide 1 with a slot is a light-diffusing film, which ensures the largest possible uniform light flux in the distribution of the entire interior space 3 (Fig. 1).

In the curved hollow, slotted light guide 1 (Fig. 11a), the light flux proceeds as follows. First, in order to optimize the propagation of the luminous flux (compare arrows 14), the cross section of the hollow, slotted light guide 1 (Fig. 11b) is outlined as a flat curve (so that this cross section is either a circle or an ellipse) and the angular dimension 90 °.

It should also be noted that the radius of curvature of the light guide 1 with the hollow slot in the curved form must be at least eight times the minimum cross-sectional size of the light guide 1 with the hollow slot.

The luminaire according to the present invention operates in the following manner. From the lamps 12 (Fig. 2) arranged in the optical input devices 6, the light flux is directed through the ends 5 to the hollow slotted light guides 1 (Fig. 1) and is passed through the light-transmitting slit 4 with sufficient uniformity into the interior 3 (Fig. 1). the impression of arches.

The shape of the light guide 1 with a hollow slot is maintained by compressed air or other gas, which is supplied by the compressor 7 through the air slot 8 and the inlet valve 9 when these are mounted on the jacket 1 'inside the light guide 1.

The heated air is discharged from the hollow slotted light guide 1 through the outlet valve 21 (Fig. 9). This valve 21 reduces the pressure inside the light guide if the air there becomes too hot.
