Description

[Detailed Description of the Invention] [Industrial Applicability] The present invention relates to optical technology, and more specifically to the interior of a building (hereinafter referred to as a building) equipped with a pneumatic support member made of a tubular body of elastic film. The present invention relates to a building/illumination device that uses the light guide that also serves as the pneumatic support member to illuminate an interior (hereinafter referred to as an interior).

The device of the present invention is suitable for use in all kinds of auxiliary buildings such as factories, hangars, exhibition halls, sports and concert venues, theaters, public buildings, etc., or buildings such as houses, shops, etc., in which the shape of the supporting member is pressurized. It can be used for lighting buildings with air-maintained inflatable pneumatic bearing members.

[Conventional technology]

Known lighting devices suitable for lighting the interior of buildings include:
The required illumination is achieved using individual lamps or floor lamps suitable for the wall or building.

Also common are devices for interior lighting that ensure uniform reflected illumination by floodlights (fl d-li axis ts) or light emitters (1 mmiMries). All known devices have a significant weight of their light illumination elements.
The use of such lighting devices in inflatable buildings is dangerous because they will fall if the internal air pressure of the support members decreases. Additionally, conventional lighting devices require electrical wires to be routed along an inflatable support member. The performance of illuminated bag counterfeiting using reflected light is limited due to the low usage factor of light flow. In order to increase the performance of this type of lighting device, the reflective effect of the inner surface of the inflatable bearing village must be increased. However, if such a requirement were to be met, the use of natural light would have to be effectively excluded, which would require a high light transmission capability of the covering material forming the exterior of the inflatable building. . Still other known lighting devices include hollow cylindrical light guides with various cross-sectional shapes, such as circular or elliptical (USSR Inventor's Certificate No. 209 302 and 1978
(See U.S. Pat. No. 3,902,066, August 26, 2013)
.

A light stream emitted from a light source is focused by an optical input device and directed through an illuminator into a light guide.
A portion of this light guide is provided with a light reflective coating on its inner surface using, for example, vacuum aluminization techniques. The light stream is multidirectionally reflected and diffused by the internal light-reflecting coating of the light guide or enters the interior to be illuminated via a section of transparent material. This light transmitting section extends over the entire length of the light guide in the lower part of the interior of the building. The shape of this hollow cylindrical light guide is maintained by a fixed ring-shaped member, and an inlet valve is provided for supplying pressurized air into the light guide and an outlet valve is provided for discharging air heated by the light source. There is. However, in order to suspend the lighting device and maintain its shape, a special support such as a cable or wire is required, or a support means must be provided to support the light guide fixedly and firmly. Such means and supports take up a lot of space.

[Problem that the invention seeks to solve]

The object of the invention is to propose a lighting device for interior lighting of buildings with an inflatable pneumatic bearing element, which makes it possible to dispense with mounting means or supports occupying a large part of the interior.

Another object of the invention is to propose a lighting device which makes it possible to eliminate any danger caused by a drop in compressed air in the pneumatic bearing member. Yet another object of the invention is to propose a lighting device that is easy to assemble and does not require external elastic wires.

[Means and effects for solving the problem] In order to achieve the above object, the present invention provides a pneumatic support member that forms the outer shell of a building with a cover material made of an elastic film and is made of a tubular body made of an elastic film. In the building/illumination device capable of supporting the outer shell in an inflated state, at least some of the pneumatic support members also serve as light guides for illuminating the interior of the building, and the surface of the tubular body of the light guide A light transmitting part is formed in the part facing the interior to be illuminated, and the other part is formed as a light reflective coating part, and at least one end of the light guide is equipped with an optical input device having at least one light source.

Ru.

Conveniently, the light guide is attached to the covering and pneumatic bearing means forming the building envelope.

Preferably, one end of at least three curved light guides is concentrated at one point, and an optical input device is attached to each of the other ends of these light guides. It is also desirable that the light guide and the covering material forming the outer shell of the building are integrated. The light-transmitting parts on the sides of the light guide can be made of the same material as the covering material forming the building envelope, in which case this light-transmitting part is hermetically bonded to the part of the light guide with the light-reflecting coating. Ru.

It is also convenient for the light guide to have at least one bend, in which case each bend is provided with a mirror for propagating a uniform light stream in the longitudinal direction of the light guide.
The present invention simplifies the assembly of lighting devices and the circuit wiring of electrical wires, which simplifies the design of buildings with pneumatic bearings and provides safety in the event of a drop in gas pressure within the building's pneumatic bearings. ensure that

The present invention allows suspension and support of large size tubular light guides to be omitted, considering that suspension and support require a solid foundation. The present invention provides a simple concentrating means to reduce the flow of heat from the light source into the interior of the building and to release excess heat from the interior. [Embodiments] Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings.

A building 11 with a pneumatic support consisting of a tubular body 1' of elastic film is supported in an inflated state by means of the pneumatic support with its shell 10 consisting of an elastic film covering.

The device according to the invention for interior lighting of a building 11 comprises a light guide 1 (FIG. 1) consisting of a tubular body 1' which also serves as at least some of the pneumatic bearing members. A part of the inner surface of the tubular body 1' is provided with a light reflecting device (coating) 2 having a high reflective effect. The tubular body 1' is an elastic film, and as shown in the figure, a light transmitting portion 4 made of a light transmitting film is provided in a portion thereof facing the interior 3. At each end 5 of the light guide 1 an optical input device 6 is attached, which device 6 is, for example, a flood lamp, a front lamp or some kind of special optical input device. The shape of the light guide of the tubular body is maintained by a pressurized gas, for example air pressurized by a compressor 7. Gas is introduced into the light guide of the tubular body via an air branch 8 and an inlet valve 9.
The light guide 1 is attached to a piece of covering material forming the outer shell of a building 11. The cover material 1 is composed of a light-transmissive polyethylene terephthal film, which allows natural light to be used during the day. Figure 2 shows light guide 1.
One end 5 of the light guide 1 (tubular body 1') is shown in detail, and the end 5 of the light guide 1 is equipped with an optical input device 6 having a light source 12, such as a metal halide irradiation lamp, in a sealed manner. are connected to each other.

The light stream from the light source 12 flows through a window 13 of transparent thermally resistive material and into the light guide.

The direction of light flow is indicated by arrow 14. FIG. 3 shows a hemispherical structure, again with a tubular light guide 1 on the meridian.
serves as a supporting or forming member.

One end 5 of each light guide 1 is optically coupled to an optical input device 6, with the ends converging at a single point 15. Such a configuration and arrangement of the light guides keeps the entire building 11 solid even in the absence of the covering material 10. In this case, it is not necessary to fix the covering material 10 to the light guides 1, and it is sufficient to simply spread the covering material 10 over these light guides 1. In order to keep a building solid as shown in Figure 3, the minimum
There must be one light guide 1. FIG. 4 is a cross-sectional view of the cover material 1, which forms the outer shell of the building, with a light guide attached thereto.

A portion of the tubular body 1' of the light guide, which is provided with a light-reflecting coating 7, is attached to the covering material 1 by adhesive tape 16. In FIG. 5, a covering material 1 forming the exterior of a building is integrated with a light guide 1, which connects the covering material 10 to a light reflective coating 2.
This is accomplished by ultrasonically welding the cover material 10 along the seam portion 17 or by adhering the covering material 10 along the seam portion 17.

The embodiment of FIG. 5 further increases the robustness of building 11 (FIG. 1). In FIG. 6, a part of the tubular body 1' of the light guide 1 is coated with a light reflective coating 2 by welding or gluing a bead 18 (FIG. 6) to the cover material 10. , is attached to the outer surface of a covering material 10 forming the outer shell of a building 11 (FIG. 1).

A light-transmitting part 4 made of a light-transmitting elastic film is hermetically connected to a part of the tubular body 1' having a light-reflecting coating, and the light-transmitting part 4 forms part of the covering material 10 of the building 11. are doing.

In FIG. 7, the light guide 1 is located inside a building 11 (FIG. 1) and the bead 18 of the light guide is attached to the cover material 10 (FIG. 7) by welding or gluing the light guide to the cover material 1. It will be done.

FIG. 8 shows a V-shaped building 11. The building 11 carries a tubular light guide having a bending angle Q.
In this case, in order to propagate the light flow into the light guide,
An optical input device 6 must be optically coupled to both ends of the light guide 1. The stability of the light guides 1 within the V-shaped building 11 is ensured simply by fitting these light guides to the covering material 10'. FIG. 9 shows an inverted U-shaped building 11.

The tubular light guide 1 has two bending angles Q and 8, which are equal or different from each other. The optical input device 6 is separated from the optical power source by an illuminator 13 (FIG. 2) and is separated from the optical input device by a groove 19 (9th point) provided in the building floor 3.
), so that the optical input device 6 is protected from mechanical stresses. To ensure the propagation of light flow,
A mirror 20 is arranged at the bending angles Q and 3, so that the optical input device 6 only needs to be provided at one end 5 of the light guide 1.

Outflow valve 2 for reducing air pressure inside the light guide 1
1 is attached to the surface of the light guide 1.

The working principle of the lighting device according to the invention for interior lighting of buildings with pneumatic bearings is based on the principle of "innumerable reflections caused by the light-reflecting coating 2 (FIG. 10) provided on the inner surface of the tubular body 1' of the light guide 1". It is based on the fact that the propagation of the light stream (see arrow 14) takes place for this reason.

As the light stream passes along the light guide 1, a part of it (see arrow 14) enters the interior 3 to be illuminated via the light transmission part 4. If the optical input device 6 is provided only at one end of the light guide 1 (FIG. 9), the ratio between the maximum cross-sectional dimension and the length of the light guide 1 is between 20 and 50. The light-transmitting part 4 of the light guide 1 is a light-diffusing film, which ensures the most uniform distribution of the light flow over the entire volume of the interior 3 (FIG. 1). Curved light guide 1 (11th
In the case of Fig. a), the propagation of the light flow is as follows.

First of all, in order to optimize the propagation of the light stream (see arrow 14), the cross-section of the light guide 1 (Fig. ), the angle i of the light transmitting part 4 is 60o to 900o
Must. It should be taken into account that the radius of the curved light guide must be at least eight times the smallest cross-sectional dimension of this light guide 1.

The operation of the lighting device of the present invention is as follows.

The light stream from the lamp 12 (FIG. 2) arranged in the light input device 6 enters the light guide 1 through the end 5 (FIG. 1).
, and passes through the light transmitting part 4 sufficiently uniformly to enter the interior 3.
(Fig. 1), giving the effect of a light arch. The shape of the light guide extends from the compressor 7 to the air conduit 8 and the tubular body 1.
It is maintained by supplying pressurized air or other pressurized gas into the interior of the light guide 1 via an inlet valve 9 provided at .

Heated air is removed from the light guide 1 via the outlet valve 21 (FIG. 9).

This valve 21 reduces the pressure within the light guide 1 if the air inside becomes too heated. When the covering material 10 forming the outer shell of the building 11 is made of a light-transmitting material, the interior of the building is well illuminated by natural light during the day.

At night, the interior is illuminated by the lighting device of the present invention. The use of light guides as pneumatic bearing members of buildings significantly reduces the financial investment in the construction and maintenance of buildings, since there is no need to use individual lighting devices that have to be assembled and supplied with light sources. I will do it.

The present invention facilitates maintenance and replacement of the light source and minimizes the number of parts required for maintenance or service. The lighting device and device of the invention make it possible to substantially improve the appearance of the entire interior and provide both natural and artificial lighting of buildings with pneumatic bearings.
