Description

[0001] The present invention relates to a lighting system which basically comprises lighting components for operating the lighting system as well as a lighting housing.

[0002] Luminaires of the type mentioned above are generally well-known. To offer and transport them, they are usually packaged. Depending on the requirements and type of luminaire, the packaging can vary considerably. Installing luminaires often generates packaging material that must be disposed of, leading to an increased volume of waste. The production and disposal of these materials also burden the environment.

[0003] To reduce packaging waste or at least make it more environmentally friendly, recyclable and preferably environmentally friendly packaging materials have been used for some time now. Paper, cardboard, or carton are frequently used materials. However, even these recyclable materials must be collected and recycled, assuming they are disposed of properly in the first place. Either way, further resources are consumed.

[0004] It is therefore an object of the present invention to provide a lighting system by means of which lights can be transported safely with low or eliminated waste.

[0005] This problem is solved by the subject matter of the independent claims. The dependent claims further develop the central idea of ​​the invention in a particularly advantageous way.

[0006] According to a first aspect, the present invention relates to a lighting system. The lighting system comprises lighting components for operating the lighting system. Furthermore, the lighting system comprises a lighting guard. The lighting guard is transformable between a packaging state on the one hand and an operating state on the other. In the packaging state, at least a part of the lighting guard forms at least a part of an outer packaging that defines a packaging space for at least partial containment of the lighting components. In the packaging state, a first side of the at least one part of the lighting guard faces inwards towards the packaging space, and a second side of the at least one part of the lighting guard faces outwards away from the packaging space.In its operating state, at least part of the luminaire guard forms at least part of a luminaire housing, which defines a luminaire compartment for at least partial accommodation of the luminaire components for the light emission of the luminaire thus formed. In its operating state, the first side faces outwards away from the luminaire compartment, and the second side faces inwards towards the luminaire compartment.

[0007] The lighting system according to the invention makes it possible for the packaging of the luminaire to be formed by its housing, or for the housing to simultaneously serve as the packaging. This significantly reduces the amount of additional packaging material, or ideally eliminates the need for disposable luminaire packaging altogether, if it can be completely transformed into at least part of the luminaire during operation.

[0008] The lamp guard is preferably designed such that it can be transformed between its packaging state and its operating state, at least by bending, folding, creasing, and / or snapping together. Thus, the lamp guard can be easily transformed between the two states: the packaging state on the one hand and the operating state on the other. Preferably, a lamp guard designed to be folded has defined fold lines to enable a defined transformation between the two states.

[0009] The lighting system preferably also includes a fixing section for securing the lamp guard in the packaging state and / or in the operating state. This makes it possible to easily hold the lamp guard in the respective state, preferably permanently and, more preferably, releasably.

[0010] The fixing section can preferably include an adhesive section, such as an adhesive strip. This allows for particularly easy fixing of the lamp guard in the respective state.

[0011] The fixing section can preferably be integrated with the luminaire guard. This eliminates the need for additional materials and components. Handling such a luminaire guard is also particularly easy.

[0012] The fixing section can preferably have a tab and / or a snap and / or an insertion section, such as a snap-in recess or a slot. A tab can, for example, be easily glued in place or inserted into a corresponding recess. Tabs can also be provided with notches or slots so that they can be hooked into corresponding recesses or into each other. Depending on the material (e.g., fiber casting), it is also conceivable that a snap-in section serves as the fixing section, which then fits into a recess to fix the lamp guard in the desired position. An insertion section, such as a snap-in recess or a slot, allows for the easy insertion of the sections to be fixed – for example, the lamp guard itself – to hold it in the desired position.

[0013] The first side may preferably have a first mounting section for attaching the lighting components to the first side in the packaging state. This mounting section could, for example, be a flat surface of the outer packaging. It is also conceivable that the mounting section is provided by a structured or contoured surface, thus providing, for example, receiving areas for the force-fit or form-fit attachment of the lighting components.

[0014] The second side may preferably have a second mounting section for attaching the lighting components in the operating state on the second side. The second mounting section may be provided in a manner comparable to the first mounting section.

[0015] The lighting system may preferably also have a first fastening section for attaching the lighting components in the packaged state to the first side, preferably to the first mounting section. This allows the lighting components to be easily and securely fixed in position in the packaged state, so that they are held in place during transport within the outer packaging. In this way, safe transport of the lighting components is easily possible.

[0016] The lighting system may preferably also have a second mounting section for attaching the lighting components to the second side, preferably to the second mounting section, during operation. This allows the lighting components to be positioned precisely during operation of the luminaire housing, thus achieving the desired light output. Furthermore, this ensures that the lighting components are securely held within the luminaire housing during operation.

[0017] The first and / or second mounting section may preferably include an adhesive section, such as an adhesive strip. This allows the lighting components to be attached in a particularly simple manner.

[0018] The first and / or second mounting section can preferably be integrated with the luminaire guard. This makes it particularly easy to provide the mounting sections and thus use them effectively.

[0019] The first and / or second fastening section may preferably have a tab and / or a snap-in section and / or an insertion section, such as a snap-in recess or a slot. This makes it possible to use the luminaire guard to fasten the luminaire components, preferably by means of a positive fit. For example, it is conceivable that the snap-in projections of the luminaire components can be snapped into corresponding insertion sections on the side of the luminaire guard, thus enabling particularly simple and intuitive fastening of the luminaire components. The fastening via the first or second fastening section is preferably releasable.

[0020] The luminaire guard can preferably have or define a light emission opening in the luminaire housing, at least in the operating state, for the emission of light from a light source housed or to be housed in the luminaire compartment. Thus, a defined light emission opening can be provided in a particularly simple manner by means of the luminaire guard to achieve the desired light emission.

[0021] The luminaire guard preferably has a locking section, at least in its packaging state, which, at least in its operating state, can be opened—for example, removed or hinged—to expose or provide access to a functional opening in the luminaire housing. Thus, a corresponding functional opening can be opened or exposed as needed.

[0022] The functional opening could, for example, be one of the insertion sections described above. It is also conceivable that the functional opening incorporates at least part of the light emission opening. This allows it to be exposed as needed, depending on the requirements and the position of the light source.

[0023] The closing section can preferably be formed, at least in the packaging state, by a weakening of the material in the lamp cover. This allows the cover section or closing section to be opened, i.e., removed or folded open, in a particularly simple manner by separating the weakening of the material, which serves as a predetermined breaking point.

[0024] The luminaire housing preferably includes a mounting section that faces outwards during operation for mounting the luminaire. This eliminates the need for additional mounting elements for the lighting system, as these are also integrated into the housing. Preferably, this mounting section can also be the first attachment section. Thus, a section used for mounting during packaging—namely, the first attachment section—can simultaneously be positioned in a concealed location, namely on the mounting side, during operation. This allows any contamination in the area of ​​the first attachment section to be easily concealed, even during operation.

[0025] The lamp housing can preferably be made of a cellulose-based material, such as paper and / or cardboard and / or corrugated board and / or molded fiber. Examples include multi-layered, reinforced cardboard, foldable corrugated board, hard paper or paperboard, as well as the aforementioned molded fiber. The cellulose-based material can preferably have a cellulose fiber content of over 50% by weight, or at least 60% by weight, or at least 70% by weight, or at least 80% by weight, or at least 90% by weight, or at least 95% by weight, or at least 97% by weight, or at least 98%, or at least 99% by weight, or 100% by weight. Depending on requirements, the material used can be provided with a surface coating. This surface coating can, for example, be an ESD coating. It is also conceivable that the surface coating could serve, for example, as part of a reflective surface for directing the light from the lamp.

[0026] The lamp guard can preferably be designed as an integral or single piece. This makes its provision and manufacture particularly simple. Handling and transformation of the lamp guard are also particularly easy in this way.

[0027] The luminaire guard can preferably be formed from several parts. At least one of these parts preferably forms at least one part of the luminaire guard. Depending on requirements, the luminaire guard can thus be provided in various shapes and configurations to enable correspondingly different shapes and designs of the luminaire to be formed with the lighting system. This also allows the luminaire guards to be designed to ensure the safe storage of the luminaire components in their packaged state.

[0028] The lamp guard components may preferably have connecting sections for joining them together in the packaging state and / or in the operating state. This allows these lamp guard components to be easily and precisely connected to each other, ensuring they remain securely fixed in the respective state. The connecting sections, like the fixing and fastening sections, may include, for example, an adhesive section such as an adhesive strip. They may also be integrally formed with the lamp guard. Furthermore, they may include a tab and / or a snap fastener and / or an insertion section, such as a snap-in recess or a slot.

[0029] The lighting system can preferably also include at least one spacer element which, in the packaged state, can be arranged or is arranged within the packaging space to position the lighting components relative to each other and / or to the outer packaging and / or to the first side in a defined manner. Alternatively or additionally, the spacer element can also be arranged or be arranged within the lighting space in the operating state to position the lighting components relative to each other and / or to the lighting housing and / or to the second side in a defined manner. Thus, further elements can also be provided which, in corresponding states, can ensure a defined arrangement of corresponding components inside the system, thereby allowing them to be arranged as needed. For example,In its packaging state, the lighting components are arranged to protect them during transport, while in its operating state they can be positioned accordingly to achieve the desired defined light output.

[0030] The luminaire guard can preferably incorporate the spacer element. This eliminates the need for additional components. If the spacers are preferably integrally or integrally formed as part of the luminaire guard, they can also be provided and handled in a particularly efficient and simple manner.

[0031] The lighting components may preferably include electrical lighting components and / or light-modifying lighting components. Examples of electrical lighting components include: a light source, such as an LED module, preferably with a lens; operating electronics for the light source(s), wherein the operating electronics include a battery (such as a rechargeable battery) and / or lighting electronics (such as a control gear); a terminal block; or any combination thereof. Examples of light-modifying lighting components include: lighting optics; a reflector; a light emission cover, such as a transparent or translucent cover, which preferably covers the light emission aperture; or any combination thereof.

The exemplary embodiment shows, for instance, a light emission cover 24 serving as a luminaire optic.

[0035] Furthermore, as can be seen in all illustrations, the lighting system 1 has a luminaire guard 3. The luminaire guard 3 can preferably be integral or one-piece formed, as is particularly evident in the Fig. 1-6 can be seen.

[0036] The lamp guard 3 can preferably be made from a cellulose-based material, such as paper and / or cardboard and / or corrugated board and / or molded fiber. For example, multi-layered material structures (such as multi-layered, reinforced cardboard), foldable corrugated board, hard paper or cardboard, as well as the previously mentioned molded fiber, are suitable. Fig. 8 and Fig. Figure 9 shows, for example, a multilayer material structure with two layers 38a, 38b.

[0038] In the packaged state, at least one part 30 of the luminaire protection 3 forms at least one part of an outer packaging 4, which defines a packaging space 40 for at least partially accommodating the luminaire components 2. As in particular the Fig. 2 and Fig. As can be seen from Figure 8, in the packaging state a first side 31 of at least one part 30 of the lamp guard 3 points inwards towards the packaging space 40, and a second side 32 of at least one part 30 of the lamp guard 3 points outwards away from the packaging space 40.

[0039] With reference to the Fig. In the operating state, at least one part 30 of the luminaire guard 3 forms at least one part of a luminaire housing 5, which defines a luminaire compartment 50 for at least partial accommodation of the luminaire components 2 for the light emission of a luminaire L thus formed. In the operating state, the first side 31 faces outwards away from the luminaire compartment 50, while the second side 32 faces inwards towards the luminaire compartment 50.

[0040] As in the Fig. 8 and Fig. As shown in Figure 9, the first side 31 can be, for example, formed by a first layer 38a of a multilayer material structure, and the second side 32 can be, for example, formed by a second layer 38b of the multilayer material structure of the luminaire protection 3 or of at least a part 30 of the luminaire protection 3.

[0041] The lamp guard 3 is preferably designed such that it can be bent, at least by means of bending (see, for example, the embodiment of the Fig. 7-9) and / or folds (see, for example, the embodiment of the Fig. 1-6) and / or folding and / or (connecting) (see all figures) and the like, is transformable between the packaging state and the operating state.

[0042] The lighting system 1 may preferably further comprise a fixing section 6 for fixing the lamp guard 3 in the packaged state and / or in the operating state. The fixing section 6 may, for example, be an adhesive section, such as an adhesive strip. The fixing section 6 may also, for example, be integrally formed with the lamp guard 3, as shown in the Fig. 2-5 visible tabs.

[0043] Overall, the fixing sections 6 can also have a similar tab and / or a snap and / or an insertion section, such as a snap-in receptacle or a slot.

[0044] The first side 31 preferably has a first mounting section 33 for attaching the lighting components 2 to the first side 31 in the packaging state. Similarly, the second side 32 can also have a second mounting section 34 for attaching the lighting components 2 to the second side 32 in the operating state. This is particularly preferred in the embodiment of Fig. 2-4 shown.

[0045] The lighting system 1 may preferably further comprise a first mounting section 7 for attaching the lighting components 2 in the packaged state to the first side 31, preferably to the first mounting section 33. Similarly, the lighting system 1 may also comprise a second mounting section 72 for attaching the lighting components 2 in the operating state to the second side 32, preferably to the second mounting section 34. The first and / or second mounting section 71, 72 may preferably have an adhesive section, such as an adhesive strip. The first and / or second mounting section 71, 72 may also be integrally formed with the lighting guard 3. Likewise, the first and / or second mounting section 71, 72 may have a tab and / or a snap and / or an insertion section, such as a snap-in recess or a slot.

[0046] The luminaire guard 3 may preferably have or define, at least in the operating state, a light emission opening 51 of the luminaire housing 5 for the emission of light from a light source 20 which is or is to be included in the luminaire space 50, as is shown, for example, in the illustrations of the Fig. 5 and Fig. 6 is evident.

[0047] The lamp guard 3 can preferably have a closing section 35 at least in the packaging state (cf. Fig. 1-3) which, at least in the operating state, can be opened, preferably removed or folded open, in order to expose or make accessible a functional opening 52 of the luminaire housing 5 (cf. Fig. 5 and Fig. 6) The functional opening 52 may preferably comprise at least a part of the light emission opening 51 (see Figure 6). Fig. 4-6). It is also conceivable that the functional opening 52 may, for example, have one of the insertion sections described above (e.g., the fastening sections 71, 72 or the fixing section 6).

[0048] The locking section 35 can preferably be formed, at least in the packaged state, by a material weakening 36 in the material of the lamp guard 3. For example, the locking section 35 can be opened or removed by separating the material weakening in the form of a predetermined breaking point. It is also conceivable that the material weakening 36 is merely separable, so that when the locking section 35 is opened, a slot is formed in the lamp guard 3. This slot can then be used, for example, as a corresponding insertion section.

[0049] The luminaire guard 3 preferably has a mounting section 37 facing outwards in the operating state for mounting the luminaire L. The mounting section 37 preferably has the first attachment section 33.
