Definitions

  • the present invention relates to an inflatable luminous body comprising an inflatable gas-tight inner shell, an outer shell that is at least partially translucent and surrounds the inner shell, means for attaching at least one lamp to the lamp in such a way that the lamp emits light into the interior of the lamp and that Light is emitted to the outside as diffuse light via translucent areas of the outer shell, as well as, if necessary, fastening means for holding the luminous element, with a fluorescent tube or a light panel being able to be attached to the inflatable luminous element as the luminous element and with the means for attaching the luminous element being designed in such a way that either bulbs or lights of different shapes and sizes can be attached to the filament.
  • An inflatable lamp is known from DE 10 2016 003 852 A1, in which the lamp is a carrier strip with light-emitting diodes, which is pushed into a pocket of the outer shell.
  • the illuminant is already integrated into the luminous element.
  • the purchaser must therefore use the light source housed in the lamp, in this case a flat LED strip.
  • Other light sources in particular those that the user already has in stock or that he can purchase on the market because he considers a specific light source to be suitable for a specific lighting requirement, are therefore out of the question for use in connection with the inflatable light body.
  • the object of the invention is to provide an inflatable luminous body with the features of the type mentioned at the outset, which is more versatile and allows a greater degree of freedom with regard to the use of the illuminant, via which the light is radiated into the interior of the luminous body.
  • the means for attaching the illuminant to the illuminant comprise one or more strips which overlap the illuminant or the luminaire when it is in the fastened state.
  • the invention thus takes a different approach than the prior art mentioned at the outset.
  • the illuminant according to the invention can be made available to the user without an illuminant, so that he is not dependent on a specific predetermined illuminant. Rather, after purchase, the user can combine a wide variety of light sources or possibly a light with the inflatable light body.
  • the illuminant itself only has the means for attaching a wide variety of illuminants, but does not have to have an illuminant itself.
  • a luminous element designed according to the invention can therefore be used in a much more flexible and versatile manner in its application.
  • the user is not limited to using the illuminant provided by the manufacturer of the illuminant.
  • the purpose of the luminous element according to the invention is to generate diffuse, soft light from the more or less directed light emitted by an illuminant or a lamp, for example linear emission from a fluorescent tube or emission from a lamp in a narrow area.
  • an illuminant or a lamp for example linear emission from a fluorescent tube or emission from a lamp in a narrow area.
  • There are different areas of application where you need such a diffuse light in particular there are such requirements for the Lighting in the film and photo area.
  • high-quality illuminants or lamps are offered here, they are not suitable for most applications for light emission with too high a luminance per unit area.
  • the luminous element according to the invention creates the possibility here of converting the light of the luminous means into soft, diffuse light in a relatively simple manner and at a reasonable cost.
  • the application of the luminous element according to the invention is not limited to a specific type of luminous element or type of lamp that generates the primary light, but that the luminous element makes no specifications with regard to the luminous element and can therefore be used very flexibly.
  • the task of the light body according to the invention is therefore not to be seen in the generation of light, but in the conversion of light into soft, diffuse light.
  • the means for attaching the lamp are designed in such a way that they are suitable for attaching either cylindrical or flat plate-shaped lamps or a lamp that is flat on the underside to the lamp body.
  • the outer shell is open on its upper side over a significant part of its length and has a longitudinal slit, with the illuminant being able to be inserted either in the region of the longitudinal slit into the outer shell from above or placed on the outer shell above the longitudinal slit and/or can be placed on the outside of the inner shell in the area of the longitudinal slot.
  • the lamp is tubular and can be inserted into the outer shell through the slot from above, the light from the lamp is emitted into the interior of the outer shell and then exits the lower translucent area as diffuse light from the outer shell outwards.
  • this can be placed on the inflatable lamp in such a way that the light is radiated through the slot into the interior of the outer shell of the lamp.
  • the flat light then sits preferably in the Longitudinal slot of the outer shell and it sits with its underside on the inner shell of the illuminant.
  • a fluorescent tube in particular an LED fluorescent tube
  • an LED fluorescent tube can be used as the illuminant.
  • Such generally cylindrical LED fluorescent tubes are available on the market in various designs and have a comparatively high luminous flux and high illuminance and also exist with battery operation. They can contain LEDs of different light colors and a control for the light color and have comparatively low operating temperatures, so that they can easily be arranged in the immediate vicinity of an outer shell of the inflatable luminous body if it consists of textile material with plastic fiber components.
  • the means for attaching the illuminant to the illuminant comprise one or more strips which overlap the illuminant or the flat lamp when it is in the fastened state.
  • the user of the inflatable light fitting thus places the light fitting or light fitting on top of the light fitting where the slot is located and then places the attachment straps over the light fitting or light fitting to detach it from the light fitting connect to.
  • One or more bands are preferably designed as a tensioning device, the tensioning length of which, which spans the illuminant or the flat lamp, is variably adjustable.
  • the means for attachment are very variable with regard to the scope of the illuminant to be attached or the light to be attached and their length can be adjusted so that they overlap the illuminant on the one hand and on the other hand attach it firmly to the illuminant by tensioning the straps .
  • the user preferably only purchases the inflatable luminous body, which does not have to have any luminous means, and can then attach a commercially available luminous means or a lamp of different size and with specific lighting properties to the luminous body in just a few simple steps exchange at any time for a differently dimensioned and/or shaped illuminant with possibly other desired lighting properties.
  • One or more straps in the form of buckle straps, elastic straps, Velcro straps or the like are particularly suitable as the means for attaching the lighting means or the light to the inflatable lighting body. If, for example, Velcro strips are used, these can be a pair of Velcro strips that are firmly attached to the outer shell of the lamp at one end, placed over the lamp or lamp in a stretched state and then at their loose ends with the stretched one State corresponding overlap are adhesively connected to each other by the Velcro material. Buckle straps or straps can also be placed over the illuminant or lamp, tightened and fixed in the tensioned state in a manner known per se. As an alternative to this, individual Velcro strips can preferably be provided in several areas, extending in the transverse direction to the longitudinal slit, which can be attached at both ends by adhering to a corresponding Velcro strip located on the outer shell.
  • the lamp body can be held in place even after the lamp or the lamp has been attached in the room, for example by hanging it from a ceiling or attaching it to a wall, using one or more fastening means that are attached to the Luminaires are attached or will be.
  • fastening means that are attached to the Luminaires are attached or will be.
  • such means for the holder do not have to be present on the luminous body itself.
  • the user can acquire an illuminant or a lamp which serves as a light source for the illuminant and on which the fastening means for holding the ensemble are already present. This is often the case because the actual illuminant or the lamp is already equipped with such fasteners.
  • fluorescent tubes can have a thread on the end face, into which ring eyelets can be screwed, which serve as holders for the luminous body. Or you can slide clamps over a fluorescent tube, to name just two examples.
  • the outer cover consists of two interconnected areas each made of a textile material, the area forming the cover top being dark on the outside and reflective on the inside, while the area forming the cover bottom being translucent.
  • the dark upper area of the outer shell does not allow any light to penetrate to the outside, but the outer shell is also reflective on the inside in the upper area, so that the light radiated into the interior of the outer shell by the illuminant is reflected there into the lower inner area of the outer shell and is thus reinforced, so that an increased light emission results over the underside translucent area of the luminous body.

  • the luminous body 10 comprises an upper area in the installed state of use with an opaque area 11 of the outer shell and a lower area 12 in which the outer shell is translucent, so that in this area diffuse light can be emitted downwards into a spatial area to be illuminated.
  • a valve 15 is arranged, for example, on the end face of the cylindrical luminous body 10 for filling with air.
  • the outer shell consisting of the two mentioned areas 11 and 12 surrounds the inflatable inner shell almost completely except for an upper area when in use, in which there is a longitudinal slit 13, which can extend over the entire length of the outer shell, so that the outer shell can be inserted into Area of this longitudinal slot 13 is open and in this area an adjustment in diameter is possible, whereby differently sized bulbs or lights can be included in the upper part of the outer shell, which will be explained in more detail below.
  • straps 14, for example Velcro straps or the like are provided on both sides of the outer shell in the region of the longitudinal slot 13. These strips 14, which span the longitudinal slot from both sides, can be fastened to the outer shell 11 or to one another, for example, in a tensioned position that corresponds to a predetermined width of the longitudinal slot 13, and in this way the illuminant can be attached to the luminous body 10. In the fastening position, the strips 14 are then stretched over the illuminant and fixed to the outer shell or to one another.
  • the outer shell can have strips of Velcro (e.g. Velcro) to which the strips 14 (e.g.
