Description

The invention relates to an inflatable filament.

Soft, precisely even light is often required for photo and film recordings. Long light sources, such as ceiling sails, illuminated surfaces or tubes, are used in particular in the photography of vehicles in order to consistently reflect in the paint. These devices are usually heavy and depend on conventional stage lights, photo flashes or fluorescent tubes.

In the prior art, heavy and bulky lights are used primarily. This leads to a large installation effort, especially for recordings that are carried out outside the studio. So stable scaffolding has to be erected and the parts have to be brought to the location for the sound and film recordings. This causes considerable costs.

It is known from the utility model DE 20 2014 003 466 U1 also a lamp that consists of two foils welded or glued together on the outer edges. These two welded / glued foils form an airtight cavity, which can be filled with air, helium or similar gases via a valve attached to the edge. A flexible LED strip is located in a strip welded onto the outside of the transparent or translucent film. This LED band shines through the air-filled cavity against the reflective / reflective film.

It is also known from the utility model DE 20 2006 007 058 U1 a lighting element consisting of an at least partially translucent lighting surface which is held by clamping elements and has at least one illuminant. The at least one clamping element spans the illumination surface along an axis of symmetry and generates a voltage in the longitudinal direction of the axis of symmetry and at right angles thereto. In a very special embodiment of the invention, the lighting fixture is designed in such a way that at least the tensioning element and possibly also all other elements used for tensioning consist of an inflatable body.

Further lighting elements are from the French patent application FR 2 995 665 A1 and the U.S. Patent Application 2012/0224359 A1 known.

The French patent application FR 2 995 665 A1 shows a lighting device jammed between an outer shell and an inflatable inner shell.

The U.S. Patent Application 2012/0224359 A1 shows a lamp with an outer shell and an inner shell. A lamp arrangement is arranged on the inner shell. The inner shell can be filled with a gas, a liquid or a solid to expand the lamp.

The object of the invention is therefore to provide a lamp which at least reduces the disadvantages which result from the prior art.

This object is achieved by a lamp according to claim 1. Special and advantageous embodiments emerge from the subclaims.

The inflatable luminous element according to the invention accordingly comprises an outer envelope which is formed from a film or a textile and is at least partially translucent in color, transparent or white.

The outer shell has an opening which is suitable for introducing an inflatable, translucent body. The inner translucent body essentially completely fills the outer shell when inflated.

To use the luminous element, an inflatable, stretchable and translucent body is introduced into the outer shell and inflated. In the inflated state, this inner translucent body exerts an outward force on the outer shell, as a result of which the outer shell expands to the maximum and thus forms a dimensionally stable luminous element. The outer shell is essentially non-stretchable.

Due to the separate inner translucent body and the sewn and or welded outer shell, the lamp body can withstand high pressure without bursting. This has decisive advantages for the stability of the filament.

The light weight of the inflatable light stick offers enormous advantages when it comes to fastening. Holding structures such as truss rigs (stage supports) or ceiling brackets can be reduced in size or even eliminated entirely. This results in a lot of potential savings in resources and construction time. Due to its design, the inflatable light stick can be attached in different ways and, thanks to its low weight, can be securely attached to inaccessible places.

According to one embodiment of the invention, the opening for introducing the inflatable translucent body can be closed with a Velcro fastener or zipper.

According to a further embodiment, the shell is half made of an opaque textile or plastic with a chamber for LED strips and the other half of a translucent opaque, white or colored textile or plastic.

The illuminant also has illuminants which shine into the illuminant. The luminous elements are preferably applied on the outside of the outer shell and shine via a section which is transparent at this point in the outer shell, e.g. a viewing window or the like, into the filament.

These lamps can be glued to the outer shell or attached to the outer shell with the help of one or more Velcro fasteners. A pocket is arranged on the outer shell over a translucent, preferably transparent section, and is designed to receive a lamp. The bag is formed by a stretchable material, which is preferably glued, welded or sewn onto the cover. The stretchability of the bag material has a decisive advantage: If the inner inflatable body expands when filled in the outer shell, it exerts pressure on the outer shell. If the bag material is not stretchable, the lamp in the bag is compressed, takes damage or leads - especially with LEDs - to changes in the color of the light.

The pocket of the inflatable luminous element is designed in such a way that it can accommodate a flexible carrier strip with light-emitting diodes. Such a carrier strip is arranged in the pocket. Normally, this does not have to be removed and the inflatable lamp can be rolled up with the carrier strip after the air has escaped via a valve.

However, there is preferably an opening in the pocket from which the carrier strip can be pulled out in order to be repaired or replaced, for example.

To transport the light rod, the tube is emptied via the valve and rolled up with the illuminant. Since the LEDs on the flexible plastic strip have sufficient protection, they do not have to be separated from the cover and wound up separately on spools. The time saved during assembly and disassembly is enormous.

The carrier strip itself also represents an independent inventive aspect, which is good to use for the inflatable luminous element or supplements it.
In order to usually bring flexible LED strips into a straight shape, they are firmly glued in rigid plastic or metal rails. This prevents them from slipping and protects them from damage and kinking. In the invention, a flexible LED strip is glued to a plastic carrier that can be rolled in the longitudinal direction. With the LEDs facing the window surface, it is pushed into the outer shell between the window layer and the stretchable bag material. By inflating the inner tube via a valve with the help of a pump, the outer shell becomes hard and stiff in the longitudinal and transverse directions and thus ensures absolute straightness and stability of the flexible LED strip.

Since the LED carrier strip is not firmly attached to the cover, it can be replaced without tools. This allows the case to be equipped and combined with different LED carrier strips depending on the color requirements.
The LED tape is preferably not visible from the outside but hidden under an elastic fabric. The function of the elastic material is to offer the LED carrier strip hold on the window surface and at the same time not to press the carrier strip firmly, but to allow scope to the outside in order not to be pressed into the outer shell by the inner tube. Given the high pressure of the hose on the outer shell, this would lead to color shifts of the LEDs and destroy the sensitive surface of the LEDs.

It is also conceivable to produce the side of the opaque outer shell from a material that is directly equipped with LEDs. The luminance of the light rod can thereby be increased.

A use in the event and furnishing area is also conceivable, since there light columns are usually provided with blowers that must be in permanent operation. The outer shell can also be printed and colored.

A particularly inexpensive luminous element is obtained if the inner translucent element is made of TPU. Inflatable TPU bodies - for example TPU tubes - are used, for example, in the kites of kite surfers. These can be used directly in some embodiments.

Preferably the inflatable filament is i.e. the outer shell and the inner translucent body are cylindrical.

The outer shell is preferably designed to be light-impermeable or light-reflecting in an area adjacent to the pocket. The outer shell below the pocket can have a transparent window.

So that the filament can be used for sound and film recordings, it must have a device for attachment to a tripod, a scaffold or the like. For this purpose, the outer cover preferably comprises at least one Velcro strip, an eyelet or loop, a metal plate or a magnet, via which the luminous element can be suspended.

In addition, devices for attaching substances for light control can be provided. Such a device can be provided by one or more Velcro strips attached to the outer shell for fastening substances for light control.

The luminous element according to the invention can be used particularly well for photographing cars if it has a length of more than 2 meters and is particularly preferably cylindrical. This results in particularly long and straight reflections in the paint of a photographed car, which are difficult or impossible to reproduce with lights from the prior art.

Particularly preferred embodiments of the invention are explained in detail below with reference to drawings. The drawings are not intended to limit the subject matter of the invention to the particular embodiment.
