The present invention relates to a lighting device, in particular for a shaft, according to the preamble of claim 1, a shaft, a use and a method for producing a lighting device.

The term "illumination device" in the present invention means a device which is designed to emit electromagnetic radiation, in particular light, preferably in the visible range or with one or more wavelengths between 380 nm to 780 nm.

Preferably, lighting devices have a light source, in particular an electric lamp, which is or is designed to generate light. Lighting devices particularly preferably have light-emitting diodes as the light source or illuminant.

A lighting device in the sense of the present invention is in particular an elongate, flexible and / or elastic device, preferably wherein the light source or the light source, in particular a plurality of light emitting diodes, along a longitudinal axis of the illumination device - is or are arranged - in particular uniformly and / or equidistantly , also called light string and / or light tube. Very particularly preferably, a lighting device is a light string or a light tube with light-emitting diodes.

Lighting devices are particularly preferably designed to generate a diffused light, preferably in order to reduce contrasts and / or shadows of an object illuminated by the illumination device, in particular of a shaft.

In the present invention, the term "shaft" is to be understood as a space which is preferably defined or delimited by length, width and height. In particular, a shaft is an enclosed and / or high or long, in particular narrow, space, such as a tunnel or tunnel construction, a mine shaft, a production well, an elevator shaft, a - preferably underground - channel, a pipe or a sewer pipe o. The like.

In many shafts bulbs are used or needed to illuminate or illuminate the shafts and / or the equipment or machinery in particular during maintenance of the shafts and / or equipment or machinery located in the shaft.

The present invention has for its object to provide an improved lighting device, a shaft with such a lighting device use and a method for producing a lighting device, whereby a safe, simple, fast and / or cost-effective installation in a shaft allows or support and / or the risk of damage is / are minimized.

The above object is achieved by a lighting device according to claim 1, by a shaft according to claim 12, a use according to claim 13 or a method according to claim 14. Advantageous developments are the subject of the dependent claims.

One aspect of the present invention resides in that the illumination device has a tensioning device which is designed to tension the flexible illumination device-at least partially-along a longitudinal axis of the illumination device in the shaft. In this way, it is ensured that the lighting device does not move in the shaft, in particular in the direction radial to the longitudinal axis. In addition, the installation of the lighting device by means of a clamping device is extremely quick and easy, especially at only two attachment points between which the lighting device is stretched.

The term "tensioning device" is to be understood in the present invention in particular a device or a tensioning mechanism, which is designed to a mechanical tension, in particular a tensile stress, preferably in the direction of the longitudinal axis of the illumination device, particularly preferably in addition to a by a force of gravity caused voltage to induce in the lighting device or to produce in the lighting device. The tensioning device preferably induces or generates a tension in the illumination device by means of an elastic deformation / elongation or change in length of the tensioning device and / or the illumination device. The tensioning device is particularly preferably a spring, in particular tension spring, or has these. However, the clamping device can also be formed in another way, in particular by or with a carrier or band.

Another aspect of the present invention, which can also be implemented independently, is that the flexible illumination device has a translucent or transparent and flexible jacket, which surrounds the illumination means of the illumination device - at least partially or completely - with the jacket outside and along or parallel to one another to the longitudinal axis and / or over the entire length of the shell is arranged on a support which is adapted to support the illumination device in the shaft and / or to tension. This allows a very simple, inexpensive and safe construction of the lighting device, in particular because the weight of the lighting device is preferably distributed on the support of the lighting device along the longitudinal axis and / or the carrier supports or stabilizes the jacket, in particular so that the jacket by the clamping operation at least substantially remains unstretched and / or the carrier receives the clamping force of the clamping element.

A further, likewise independently realizable aspect of the present invention is that the flexible illumination device is arranged on a band as a carrier, which is designed to support and / or to tension the illumination device in the shaft. In this way, corresponding advantages can be achieved. In addition, a band as a carrier allows a very weight-saving and therefore also safe construction of the lighting device.

Another, likewise independently realizable aspect of the present invention relates to a lighting device in which the lighting device is connected by securing elements of a, preferably transparent, injection molding material with a, preferably band, rope and / or belt-like, carrier. This allows a particularly secure and reliable connection of the illumination device with the carrier, which can also be carried out in an advantageous manner translucent, retrofitted and even with endless material.

The term "band" in the present invention is preferably to be understood as meaning an elongated object which is in particular designed to transmit tensile forces. A band is according to this understanding in particular a rope, strip, belt, belt o. The like. In particular, a band is at least substantially stretch-resistant and / or a flexible and / or elastic element, which preferably comprises a knitted fabric, woven or knitted fabric, in particular of fibers, such as glass and / or carbon fibers, and / or wires, or is formed as such and / or from or with Plastic, in particular made of elastomers, preferably injection-molded.

In this way, a particularly secure attachment or connection between the carrier or tape and the lighting device and a cost-effective production of the lighting device is ensured.

Preferably, the bulbs are electrically connected and / or connected within the shell, in particular by a line, flexible printed circuit boards, printed circuit boards, cables o. The like. In a variant, the carrier or the band is designed as a carrier, the lighting device, in particular the light source to provide electrical energy, and / or the carrier or the band is at least partially electrically conductive. This allows a very compact and lightweight design of the lighting device.

In a further variant of the illumination device, the illumination device is arranged on a front side and a rear side of the carrier or the band and / or spirally or along a helix on the carrier or the band as a carrier and / or is the carrier or the band arranged between two lighting devices. In this way it is ensured that the lighting device always sufficiently illuminates the shaft, even if the lighting device rotates in the shaft. In addition, such a lighting device can be installed very quickly, since the orientation of the lighting device in the shaft, the illumination of the shaft is independent.

Particularly preferably, the illumination device and / or the carrier or the band has or have one or more attachment means for attachment to or on the tensioning device and / or in the shaft.

Alternatively or additionally, the tensioning device can be connected at several points to the illumination device and / or the carrier or the band. In this way, the illumination device can be fixed or fixed and / or tensioned at least substantially independently of the conditions in the respective shaft. In particular, the lighting device can be fastened or fixed and / or tensioned in differently long or deep shafts.

Alternatively or additionally, the length of the lighting device by means of the clamping device and / or the carrier or the belt is variable, preferably wherein the clamping device and / or the carrier or the belt has a spring and / or a tension belt. In this way, corresponding advantages can be achieved.

Another, independently realizable aspect of the invention relates to a shaft having a lighting device as described above. The illumination device is preferably tensioned in the well, along the well, and / or over at least substantially the entire length of the well. In particular, it is a vertical-elongated shaft, particularly preferably an elevator shaft or other shaft whose length its (maximum or minimum) diameter by at least 50%, preferably more than 3 or 5 times, in particular more than 10th -fold exceeds.

In a proposed use of a clamping device is provided to stretch a flexible illumination device in a shaft - at least partially - along a longitudinal axis of the illumination device, wherein the illumination device has at least two lighting means, which are arranged along the longitudinal axis of the illumination device. In this way, the lighting device can safely, quickly and / or easily secure in the shaft. In addition, the advantages already described can be achieved.

A further, independently realizable aspect of the invention provides for a use of a band, wherein a band is used for fastening and / or tensioning a flexible illumination device in a shaft, wherein the illumination device has at least two light sources arranged along a longitudinal axis of the illumination device , and wherein the illumination device is arranged on the band as a carrier. In this way, corresponding advantages can also be achieved in practice.

Particularly preferred is a mounting or use, in which the illumination device with its longitudinal axis extends at least substantially vertically. However, there are also applications with at least substantially horizontal course of the longitudinal axis of the lighting device. Here, it is preferred that the illumination device has a length of only a few meters, for example less than 10 m, preferably less than 8 m or 6 m, or is held additionally vertically at such a distance.

Another, independently realizable aspect of the invention relates to a method for producing a lighting device, in which an elongated, flexible illumination device, in particular a light tube, arranged with a along its longitudinal extent, preferably band, rope and / or belt-like, carrier by a Injection molding is connected, so that the illumination device by tensioning the carrier at least substantially the, preferably by the tensioning straight or linear course of the carrier follows. By using an injection molding process, a particularly reliable connection of the illumination device to the carrier can be achieved, which, moreover, can advantageously be produced from the side and thus also with endless material.

The above aspects and other aspects and features resulting from the claims and the description below may be implemented independently of each other and in any combination.

In the following, further, particularly preferred embodiments will be explained, wherein to avoid repetition, essentially differences to the previously explained embodiments will be discussed in more detail. The aspects, features and advantages described above therefore apply correspondingly or additionally.

Fig. 5 shows an enlarged schematic view of a portion of a proposed lighting device 1. In Fig. 5 are different sections of this lighting device 1 separated by break lines to allow an explanation by means of partial enlargements.

The lighting device 1 has one or more lighting devices 3. The illumination device 3 is particularly preferably a so-called light tube or a row of light sources 4, in particular light-emitting diodes, which are surrounded by a light-transmissive jacket 16.

In the illustrated example, the lighting means 4 are arranged on a plurality of flexible printed circuit boards 15. The printed circuit boards 15 can be electrically and / or mechanically interconnected with connecting elements 15A. The connecting elements 15A may be insulated wires, connectors or the like.

The lighting device 3 is preferably designed to be separable in the region of the connecting elements 15A while maintaining the lighting function. In this way, the lighting device 3 or the lighting device 1 can be shortened in length.

The light-emitting means 4 are preferably arranged in the preferably tubular jacket 16. The jacket 16 is preferably translucent, so that light emitted by the lighting means 4 can exit through the jacket 16. In particular, the jacket 16, at least partially or on one side, which is provided for the light exit, formed of transparent, transparent or translucent material.

The light sources 4 may be mechanically or indirectly connected to an inner side of a wall forming the jacket 16. This can prevent the bulbs 4 from slipping.

The shell 16 is preferably provided at the end with a closure 16 A, which blocks the ingress of water or foreign substances in the interior formed by the shell 16. In particular, the closure 16A is a cap, a housing, an adapter or the like.

The closure 16A preferably has a passage 10A for passing the port 10 and the conduit 14, respectively, from the environment into the volume formed by the shell 16. The passage 10A is preferably designed to seal the connection 10 or the line 14 with respect to the closure 16A or the jacket 16. Alternatively or additionally, a passage region of the connection 10 or the line 14 may be encapsulated with a potting compound 10B, in particular silicone, acrylic, polymer or the like, whereby the passage can be formed.

In the representation example according to Fig. 5 only one end or an end face of the jacket 16 is shown. The opposite front side or the opposite However, the end of the jacket 16 may be closed and / or sealed in a corresponding manner. However, an implementation is not necessarily provided here since the voltage supply of the lighting means 4 can take place on one side.

Along the illumination device 3, the illumination device 1 preferably has the carrier 17. As already explained above, it is a preferably band-like or belt-like carrier 17. The carrier 17 is preferably more rigid in comparison to the jacket 16 or the lighting device 3 and connected to the illumination device 3, in particular the jacket 16. Due to the tensile rigidity of the carrier 17 this can be stretched and hold the lighting device 3 in a particular position and support in the tensioned state. The lighting device 1 is preferably windable for transport. For this purpose, the carrier 17 is preferably bendable.

In the representation example according to Fig. 5 is the carrier 17 for clamping with the tensioning device 5, in particular the spring 21, connected. However, the carrier 17 can also be tensioned in other ways.

The carrier 17 may be provided on or along the illumination device 3, but only connected to the illumination device 3 by the securing elements 19. Between the securing elements 19, the carrier 17 can therefore be guided loosely on, along or next to the carrier 17.

The carrier 17 is preferably connected by securing elements 19 with the jacket 16. In this way, the lighting device 3 can be supported or held, in particular by the conditional by the weight of the lighting device 3 force is derived via the securing elements 19 in the carrier 17. As a result, a longitudinal expansion of the illumination device 3 is avoided.

The carrier 17 preferably assumes by tensioning an at least substantially straight or linear shape, which follows the illumination device 3, in particular due to the attachment of the jacket 16 to the carrier 17, which can be done by the securing elements 19, in sections or at least substantially without interruption.

The support 17 is preferably connected to the illumination device 3 or the shell 16 by a plastic casting process, particularly preferably injection molding, with each other.

In any case, the illumination device 3 or the jacket 16 as well as the carrier 17 are particularly preferably cast or cast in sections, in particular by means of injection molding technology and / or with the formation of the securing element 19A.

Preferably, a plurality of securing elements 19 are provided, which are each produced by means of injection molding or injection molded parts. These are preferably translucent. The illumination device 3 is preferably at least partially held by the securing elements 19 on the carrier 17. This has proved to be particularly durable, easy to manufacture and advantageous in terms of the manufacturability of different length lighting devices 1. In particular, the securing elements 19 can be mounted around the illumination device 3 even with longer illumination devices 3 from the side, whereby a complicated slipping along the illumination device 3 and the use of clamps or other error-prone, multi-part fasteners are avoided.

The securing elements 19 are preferably translucent or transparent, in particular transparent, translucent or the like. In this way, fuse elements 19 can also extend over light-emitting means 4, without shadowing them. This advantageously allows a very stable, secure, reliable and robust attachment of the illumination device 3 to the carrier 17, without losses in terms of the light output.

Preferably, one or more fuse elements 19 are molded onto the illumination device 3 or to the jacket 16. In a particularly preferred embodiment, the illumination device 3 or the jacket 16, with the securing element 19 is or at least substantially encapsulated in an annular manner.

Alternatively or additionally, it is preferred that the carrier 17 is connected to the securing element 19, in particular wherein the securing element 19 is injection-molded onto the carrier 17 and / or the carrier 17 is injected into the securing element 19 is. This allows a particularly secure and durable connection with the carrier 17th

The respective securing element 19 is or is preferably formed in one piece.

Preferably, the lighting device 3 has a first and a different second variant of securing elements 19.

Here, the first variant of securing elements 19A is preferably fixed, non-detachable or non-destructive releasably connected to the illumination device 3 and the jacket 16. Securing elements 19A of this variant preferably form a material connection between the carrier 17 and the illumination device 3 or the jacket 16, in particular by the securing element 19 being glued, welded or fused together both with the carrier 17 and with the illumination device 3.

A securing element 19A of the first variant is preferably provided in any case at one end of the lighting device 1 or lighting device 3, in particular the end provided in the position of use above or on the shaft ceiling. Only one or more securing elements 19A of the first variant may be provided, in particular each at an upper end of an illumination device 3 in use position, at both ends of one or the respective illumination device 3 or also several times in the course of the illumination device 3. the support 17 is permanently connected to the illumination device 3 continuously or at certain intervals via securing elements 19A. It can therefore be provided only fuse elements 19A of the first variant.

A second variant of securing elements 19B forms a preferably force-releasable, overcoming, frictional and / or frictional, in particular clamping, connection between the carrier 17 and the illumination device 3 or the jacket 16. In particular, fuse elements 19B of the second variant hold the illumination device 3 or the jacket 16 on the support 17 such that the illumination device 3 or the jacket 16 opposite to the carrier 17 against or against overcoming a holding force or force threshold is displaceable. The holding force or force threshold preferably exceeds the weight force generated by a section of the illumination device 3 between two securing elements 19B, in particular by at least 10%, preferably more than 30% or 50%. As a result, slippage of the lighting device 3 is inhibited.

This makes it possible to hold the lighting device 3 in position and support by means of the carrier 17, but at the same time to allow a certain degree of relative movement relative to one another when tension or changes in length of the lighting device 3 occur. In this way, it can be avoided that damage can occur in the case of very long lighting devices 1, in particular with several tens of meters, tensile stresses acting through thermal expansions or on parts of the lighting devices 3.

Preferably, the securing elements 19B are sprayed under pressure in such a way that the preferably relatively soft shell 16 escapes the material of the securing element 19 and in this way creates a slight constriction of the shell 16, which is filled by material of the securing element 19B. In this way, the intended holding force can be achieved, since for a displacement, the force must be sufficient to deform the shell 16. In order to prevent the securing element 19 from sticking to the casing 16 or forming a material bond and as a result being no longer displaceable, a separating agent may be or may be provided between the casing 16 and the material forming the securing element 19B during the injection process.

In the representation example according to Fig. 5 the securing element 19B is connected to the carrier 17 by abutting the casing 16 on the outside in a clamping and / or non-positive and / or frictionally engaged manner. In principle, however, it is also conceivable that the securing element 19B is fixedly connected to the casing 16 and the carrier 17 is held on the securing element 19B in a clamping, frictional and / or force-locking manner on the carrier 17. In both cases, it is preferably provided that the carrier 17 is displaceable relative to the illumination device 3 or the jacket 16 in the case of larger forces acting counter to the illumination device 3 and the carrier 17 in the longitudinal direction. The securing element 19B is thus displaceable on the illumination device 3 and / or the carrier 17.

Preferably, a shaft 2 or the use of the lighting device 1 in the shaft 2, wherein at a top in use position arranged end of the lighting device 1 of the carrier 17 with the lighting device 3 and the shell 16 is immovable or rigidly connected. For this purpose, preferably a fixed or rigidly connected to the lighting device 3 and the jacket 16 and the carrier 17 fuse element 19A at one end of the illumination device 3, which is in particular attached to an upper position in use position attachment point. Further securing elements 19 may be designed as securing elements 19B of the second variant, in any case to enable a displacement of the carrier 17 relative to the illumination device 3 or the jacket 16 when overcoming a certain holding force or force threshold.

Fig. 6 shows a schematic section of the lighting device 1 according to the section line VI-VI Fig. 5 ,

The jacket 16 preferably forms a tube which is flattened round, oval and / or one-sided. This facilitates the arrangement of the lighting means 4 or the printed circuit board 15 in the hose 16 formed by the jacket 16 and the arrangement of the carrier 17, preferably adjacent and / or on a side of the jacket 16 facing away from the lighting means 4 or the printed circuit board 15.

The carrier 17 is preferably connected to the jacket 16 by the securing element 19, which is preferably formed in the representation example by a light-permeable injection molded part. This injection-molded part preferably includes both the shell 16 and the carrier 17, so at least in sections, in particular ring-shaped or annular surrounds. In this way, a particularly secure, force distributing connection between the carrier 17 and the illumination device 3 or the jacket 16 can be achieved.

The carrier 17 is preferably provided along the entire longitudinal extent of the illumination device 3 and in particular for attachment to the ends, preferably a few centimeters beyond the illumination device 3 addition.

It is possible, but not mandatory, that the carrier 17 is connected without interruption along the entire illumination device 3 with this. It may be provided that the illumination device 3 is connected to the carrier 17 only or at least essentially only via the securing elements 19. Here, the fuse elements 19 may be provided at a certain distance from each other and the carrier 17 between the fuse elements 19 spaced from the illumination device 3, only loosely rest, at least be guided substantially along or parallel to the illumination device 3 and the jacket 16.

The injection-molded securing elements 19A, 19B can be spaced from each other by an average distance of more than 10 cm, preferably more than 20 cm, in particular at least 50 cm and / or less than 2 m, preferably less than 1.50 m, in particular at most 1 m be arranged. This allows a resource-saving production and good handling, since the flexibility of the lighting device 3 and the support 17 in any case predominantly or outside the securing elements 19 is maintained and consequently the lighting device 1 remains sufficiently flexible to be wound up for transport. In particular, the lighting device 1 can be bent at least in the direction of the carrier 17 with a radius of less than 30 cm, preferably less than 15 cm, in particular less than 10 cm.

In the FIGS. 7 to 9 schematic sections of a further variant of the proposed lighting device 1 are shown. In this variant, it is provided that the carrier 17 is used to supply the lighting means 4 with electrical voltage. In particular, two at least partially conductive supports 17 are provided, which form the power supply for the lighting means 4. For this purpose, a conductive outer jacket 17B may be provided around a tension-absorbing core 17A or vice versa. In principle, the carrier or carriers 17 can also be designed in another way for both power supply and clamping, for example by the carrier or carriers 17 being conductively coated or having conductive or conductively coated components such as strands, fibers or strands.

The conductive carriers 17 or layers are preferably electrically connected to the line 14, so that the lighting means 4 can be supplied with power.

In the representation example according to Fig. 7 two carriers 17 are provided, which each form a connection for supplying voltage to the lighting means 4. Alternatively or additionally, however, another, for example, coaxial structure can be selected, in which the carrier 17 has a plurality of separate electrical lines for supplying the lighting means 4.

The carrier or carriers 17 preferably have one or more fastening elements 24 at the end of the illumination device, in particular in the form of thickenings 19D on. In particular, these may be pressed-on elements such as rings, sleeves or the like.

It is further preferred for the carrier or carriers 17, in particular the region or regions with the fastening elements 24, to be received, injected or cast in a preferably cap-like closure 16B, so that the carrier 17 can be tensioned with the closure 16B.

The illumination device 3 and / or the carrier 17 or the band 18 preferably have only two attachment means 20, which are preferably arranged at opposite ends of the carrier 17 and / or are adapted to allow an attachment and a tensioning of the illumination device 1. In principle, the lighting device can also have a plurality of fastening means 20 and / or the clamping device 5 can be connectable at several points to the lighting device 3 and / or the carrier 17 or the band 18, in particular as already explained above.

The embodiments and the features of the present invention described in these contexts can also be combined with each other. In particular, in the embodiment according to Fig. 5 Also be provided that the jacket 16 is closed at the end or front side with the securing element 19A. Furthermore, it can be provided that the carrier 17 is fixed by pouring or injecting into the securing element 19A and the lighting device is tensioned with the securing element 19A.

According to a further alternative, the lighting device 1 can also for lighting for other purposes, outdoors, for, preferably elongated, rooms, halls or the like. be used. In particular, the lighting device or the like for garages, engine rooms or the like. be used or rooms, especially garages, engine rooms, elevator machinery rooms or the like. with a proposed lighting device can form aspects of the invention.
