Abstract

The invention relates to an inflatable lighting body for use in photographic and cinematographic shooting sessions. The lighting body has an outer skin (1, 8) which is dimensionally-stable when inflated, is made of a film or fabric and which is at least partially translucent coloured, transparent or white. The outer skin (1, 8) has an opening (2) for inserting an inflatable translucent body (17), which, when inflated, exerts a force that is directed outwards on the outer skin (1, 8) and expands the outer skin to a maximum extent, thus forming a dimensionally-stable lighting body.

Title:

Inflatable lamp

Description :

The invention relates to an inflatable luminous body.

When shooting photos and film, a soft, even, uniform light is often needed. Especially in the photography of vehicles, long light sources, such as ceiling light panels or fluorescent tubes are used to reflect throughout the paint. These devices are usually heavy and dependent on conventional stage lights, photo flashes or fluorescent tubes.

In the prior art, especially heavy and bulky lights are used. This leads to a large installation effort, especially for recordings made outside the studio. So stable frameworks must build who took this ^¬ and the parts to the place for sound and film on ^¬ be spent. This causes significant costs.

The object of the invention is therefore to provide a lamp be ^¬ riding determine which, at least reduces the disadvantages resulting from the prior art.

This object is achieved by a luminaire according to claim 1. Particular and advantageous embodiments will become apparent from the dependent claims. The inflatable luminous body according to the invention therefore comprises an outer shell, which is formed from a film or a textile and is at least partially translucent colored, trans ^¬ parent or white.

The outer envelope has an opening which is suitable for troduction ^¬ ren an inflatable translucent body. Preferably, the inner translucent body substantially completely fills the outer shell in the inflated state. For use of the filament an inflatable, elastic and translucent body is inserted and inflated in the outer shell. When inflated, this internal translucent body exerts an outward force on the outer shell, whereby the outer shell maximum expan diert ^¬ and thus forms a dimensionally stable filament. The outer shell is essentially not stretchable ^{ausgebil ¬} det.

The separate inner translucent body and the sewn and or welded outer shell of the luminaire can withstand high pressure without this bursts. This has decisive advantages for the stability of the filament.

The low weight of the inflatable light stick offers enormous advantages in attachment and use. Holding constructions such as Trussrigs (stage holders) or ceiling fixtures can thereby be downsized or even completely eliminated. This results in a lot of saving potential in resources and construction time. The inflatable light stick can be mounted in different ways due to be ^¬ nes design and is sure to fasten thanks to its low weight in inaccessible places. This results - especially by the low weight - new flexible application possibilities ^¬ possible.

According to one embodiment of the invention, the opening for insertion of the inflatable translucent body with a Velcro and / or zipper is closed.

According to a further embodiment, the sheath is at the "upper" half of an opaque fabric or plastic formed with a chamber for LED strip and the other half from a light-transmissive opaque, white or colored textile or plastic. In this case, the off ^¬ pressure "refers upper "half of the part of the filament, wel ^¬ cher in the suspended state has upwards.

The luminaire has lighting means which illuminate into the luminous body. Preferably, the luminous bodies are applied to the outside of the outer shell and shine over a section which is transparent at this point of the outer shell, e.g. a viewing window or the like, into the luminous body.

These bulbs can be glued to the outer shell or attached by means of one or more Velcro straps on the outer shell. Preferably, however, arranged on the outer shell over a translucent, preferably transparent portion, a pocket which is adapted to receive a lighting means. Preferably, the Ta ^¬ cal is formed by a stretchable fabric which is adhered to the sheath is welded or sewn on. The Dehn ^¬ bility of the pouch material has an important advantage: When the inner inflatable body expands during filling of the outer sheath, it exerts a pressure on the outer shell out. If the bag material is not stretchable, the light ^¬ medium is compressed in the bag, takes damage or leads - especially in LEDs - to color changes in the light.

The pocket of the inflatable luminous body is preferably designed such that it can receive a flexible carrier strip with light-emitting diodes. Or it is such a carrier strip arranged in the pocket. Normally, this does not have to be removed and the inflatable light ^¬ body can be rolled together with the carrier strip after the escape of air through a valve.

Preferably, however, there is an opening in the pocket, from which the carrier strip can be pulled out or lifted out, for example, to be repaired or replaced.

Preferably, the pocket has an opening extending along the length of the pocket and more preferably extends over a majority of the overall length of the pocket.

According to one embodiment, is configured that the opening by a preferably continuous zipper occlusive ^¬ bar. By extending in the longitudinal direction opening, which extends over a majority (preferably more than 80% of the total length of the bag), it is possible the bulbs in the inflated state of the filament from ^¬ exchange. This is made possible especially by the easy to öff ^¬ nenden zipper. But other closure ^¬ systems offer certain advantages, such as Velcro or magnetic ^{¬ closures} .

Particularly preferably, the pocket is formed from two tabs extending in the longitudinal direction of the luminous element. These tabs are preferably each with a longitudinal direction Side edge attached to the outer shell of the filament They are preferably formed of a flexible material and ^¬ who preferably connected to each other via a zipper, so that a bag is formed. Lateral remain even with closed zipper, which can preferably be closed by Velcro strips ^¬ and can serve as a cable guide, for example.

According to a further embodiment it is provided that adjacent to the opening of the pocket regions to - so the tabs - can be folded away from the opening to the outside, so that it is below the pocket partially the transparent window ^¬, largely or completely free. This makes it possible to use other light sources, which are not in the bag pas ^¬ sen, introduce them to the transparent window and thus to use. In this case, the tabs adjacent to the opening of the pocket act to reduce the stray light by preventing or reducing a lateral blasting or Vorbeistrahlen the zoomed light sources. According to one embodiment, magnets or Velcro strips can be provided for this purpose, which allow attachment of the tabs to the light sources brought up.

To transport the light rod, the hose is emptied through the valve and rolled up with the light bulb. Since the LEDs on the flexible plastic strip have enough protection, they need not be separated from the case and wound separately on spools. The time savings in assembly and disassembly is enormous.

The carrier strip itself also represents an independently inventive aspect, which is good for the inflatable luminous body or to complement it. The LED Strip preferably has a rolling radius which corresponds to the rolling radius of the inflatable filament. LED bulbs of the prior art often have too large a rolling radius.

According to a further embodiment, the inflatable luminous body has a flexible LED strip, which is connected to a control unit for controlling the LEDs. It can be provided that the LEDs are controlled jointly, individually or in groups. According to a particularly preferred embodiment it is provided that the controller has a transmitting and receiving unit, which makes it possible to wirelessly control the filament and further preferably to operate with other LED strips in a common application. According to a particular embodiment, it is provided that the light-emitting diodes are all first turned on in a control program. The first LEDs and in time sequence further, adjoining LEDs turned off in the longitudinal direction of the luminous body, to a previously festgeleg ^¬ ter area is switched off at one end of the filament - Next, - starting from one side of the luminous element. Then, this area is switched off LEDs migrates to the other side of the luminous body and decreases as ^¬ raufhin until again, all LEDs of the luminous body are on. The light reflexes that arise in this type of control on a parked under the lamp motor vehicle, create the impression as if the motor vehicle moves under neon tubes, which are hung longitudinal to the direction of travel of the motor vehicle, for example, on the ceiling of a parking garage or in a tunnel. In order to bring flexible LED strips normally in a rectilinear shape, these are firmly glued into rigid plastic or metal ^{rails ¬} . As a result, they do not slip and are protected from damage and kinking. In the invention, a flexible LED strip is glued to a longitudinally rollable plastic carrier. This is, with the LEDs turned to the window surface, gescho ^¬ ben in the outer shell between ^¬ window layer and the stretchable bag material. The outer shell is hard and stiff in the longitudinal ^¬ and transverse direction by inflation of the inner tube via a valve with the aid of a pump, thus ensuring absolute straightness and stability of the flexible LED strip.

Since the LED carrier strip is not firmly connected to the shell, it can be replaced without tools. This allows the case with different LED carrier strips are equipped and combined depending on the color desired.

The LED band is preferably not visible from the outside but hidden under an elastic fabric. The function of the elastic fabric is to provide the LED carrier strip stop on the window surface and at the same time not to press the carrier strip firmly, but to provide clearance to the outside so as not to be pressed by the inner tube in the outer shell. This would lead to color shifts of the LEDS at the high pressure of the hose on the outer shell and destroy the sensitive surface of the LEDs.

It is also conceivable to produce the side of the opaque outer shell of a fabric that is directly equipped with LEDs. As a result, the luminance of the light rod can be increased. A use in the event and equipment area is also conceivable, since there light columns are usually provided with blowers that must be permanently in operation. The outer shell can also be printed and colored.

A particularly cost-effective luminous body is obtained when the inner translucent body is made of TPU. Inflation ^¬ bare TPU body - for example TPU hoses - are for instance used the screens of kite surfers used. These may be used directly in some embodiments.

Preferably, the inflatable luminous element is that the outer shell and the inner ^¬ translucent body formed cylindrically from ^¬. According to further preferred embodiments, the inner, translucent body and the outer shell are cube or qua ^¬ shaped.

Preferably, the outer shell is in an adjoining the pocket ^¬ the area opaque or light-reflective forms out ^¬ is. The outer shell below the bag can have a transparent window. However, according to other embodiments, the outer shell may also be translucent or transparent everywhere.

In order for the luminaire to be used in sound and film recordings, it must have a device for attachment to a tripod, a framework or the like. For this purpose, the outer shell preferably comprises at least one Velcro strip, an eyelet or loop, a metal plate or a magnet over which the luminous element can be suspended.

In addition, devices for fastening materials for light control can be provided. Such a device may be given by one or more attached to the outer skin Velcro strips for attachment of materials for lighting control.

The luminous body according to the invention can be used by cars particularly suitable for Fo ^¬ tografie if it has a length of over 2 meters and is particularly preferably zylinderför ^¬ mig formed. This results in the paint of a photographed car particularly long and straight reflections that are only partially or not reproducible with lights from the prior art.

In the following, particularly preferred embodiments of the invention are explained in detail with reference to drawings. The drawings are not intended to limit the subject matter of the invention to the particular embodiment.

On the top of the shell, an elastic textile 3 is eingear ^¬ processed, which holds an underlying carrier strip with light emitting diodes 15 on a transparent window film 16.

Between the two layers a carrier strip is accordingly incorporated with light emitting diodes 15, so that the light exiting ^¬ takes place to the shell bottom. 8

For introducing the carrier strip with light-emitting diodes 15, a zipper is incorporated into the elastic textile 3 or into the pocket, which runs in the longitudinal direction of the luminous body approximately over the entire length of the elastic textile 3 and thus also over the entire length of the filament. When the zipper is opened, the textile arranged laterally to the zipper can be folded outwards.

By means of a valve 10, an inner tube 17 is inflated, which biases the outer shell so that the object is fixed and stiff in the longitudinal and transverse axis.

By the fastening tape 4 can be fixed by means of the sewn Velcro strips 5 of the light rod. The sewn-in metal plate 6 is used to attach a magnetic holder.

The Velcro strips 7, 9 and 13 are used for attachment of fabrics or plastic plates that hang perpendicular to the light stick and limit the light emission side and control the light. Through the zipper 2, the inner tube is inserted into the light stick. The reinforcing tapes 11 and 14 Schütting ^¬ zen the bag 3 at the lateral opening and the cable exit.

On the eyelets 12, the light tube can be secured or suspended.

The light tube may have a length of 1 to 25 meters and a diameter of 5 to 50cm or more.

The light stick can be rolled up with the LEDs in the deflated state.

Depending on the length of the luminous rod, the shell top is provided with different numbers of fastening ^¬ bands 4. The Velcro tape 5 is intended for attachment of the light stick as well as the metal plate 6 by a magnetic holder. Via the valve 10 we inflated the inner tube. The reinforcing tapes 11 and 14 are intended to protect the shell top 1 and protect the lateral opening of the bag 3 by mechanical stress. The eyelets 12 are used for fastening and securing the light stick.

According to FIG. 6 and FIG. 7, the inner tube 17 is made of a transparent and expandable material which, when inflated via valve 10, assumes the shape of the glowing stick. The stronger the hose is inflated the more stable is the glow stick. The tube is welded airtight at the ends by a transverse weld 19. The loose end 20 remains on the inner ^¬ hose, the longitudinal weld seam 18 is not as üb ^¬ Lich at the outer edge of the tube 17 but is engaged over the entire length, so that it lies in at ^¬ pumped state at the bag top 1 to the center and not visible in the casing bottom 9.

FIG. 8: A plastic window film 16 is sewn or welded into the shell top 1. In addition, a protective ^¬ zender flexible textile or plastic strip 3 is welded or sewn. Between the two layers of the carrier strip 15 is pushed with the glued LED strips, so that the LEDS shine through the plastic window foil on the cover bottom ^¬ 8. Fig. 9 shows the light rod holder 24 consisting of a plastic bridge 22 which is provided with 2 magnets 23 and a holding rod 21. The magnets 23 are attached to the light stick in the inflated state to the metal plate 6. The support rod 21 can be mounted in a sleeve and holds the light stick in the desired position.
