[0002] Description:

[0003] Technical area

[0004] The present invention relates to a lighting kit and a modular light assembled on the basis of the lighting kit.

[0005] Background of the invention

[0006] Luminaires known from the prior art are typically assemblies with a multitude of components attached to one another. Typical designs include, for example, a housing, a device carrier that supports electrical components and, in particular, the luminaire's light source, and a light-emitting element that is used for the directed distribution and / or scattering of the light emitted by the light source.

[0007] The locations of the luminaires and also the applications can be of different types, which also place different demands on the respective luminaires.

[0008] For example, the location of use can be a damp room or an outdoor area, where different requirements must be placed on the luminaire than in the case of a “normal” dry room.

[0009] Likewise, the types of lighting can vary greatly depending on the application. Examples include direct lighting and indirect lighting.

[0010] In order to meet these numerous and diverse requirements, manufacturers usually offer a variety of different luminaires in a wide range of categories, for example the categories “interior luminaires” or “outdoor luminaires”.

[0011] Providing such a wide range of luminaires involves high costs and a high level of effort in production and marketing.

[0012] Summary

[0013] The present invention is based on the object of creating a more efficient way of providing and adapting luminaires to a wide variety of application conditions.

[0014] To achieve this object, a lighting kit according to claim i and a modular light assembled on the basis thereof according to claim 25 are provided. The respective dependent claims relate to preferred embodiments, which can each be provided individually or in combination.

[0015] According to a first aspect of the invention, a luminaire kit for providing a modular luminaire is provided, comprising a device carrier configured to receive a light source, a set of light-emitting elements comprising at least two differently configured light-emitting elements, and a set of housings comprising at least two differently configured housings. The device carrier comprises a first receiving section for receiving a light-emitting element and a second receiving section for receiving a housing.Each light-emitting element of the set of light-emitting elements comprises a first interface section which is adapted to the first receiving section of the device carrier, and each housing of the set of housings comprises a second interface section which is adapted to the second receiving section of the device carrier, such that a modular luminaire is composed of at least the device carrier, a light-emitting element from the set of light-emitting elements received on the device carrier, and a housing from the set of housings received on the device carrier, wherein the first interface section of the received light-emitting element is brought into interaction with the first receiving section of the device carrier and the second interface section of the received housing is brought into interaction with the second receiving section of the device carrier.

[0016] The housings are preferably understood to mean elements which, in the assembled state of the modular luminaire, partially or completely delimit at least a part of the modular luminaire, in particular its electrical components, from an environment of the modular luminaire.

[0017] Light-emitting elements are preferably understood to mean any type of element that, when the modular luminaire is assembled, is designed to distribute and / or focus and / or scatter the light emitted by the lamp in an area surrounding the modular luminaire. For example, these can be light guides, diffusers, or the like.

[0018] The luminaire kit described above provides a kit for a modularly constructed or modular luminaire, which can be quickly and easily equipped with various housings and light emitting elements starting from the device carrier acting as a universal interface in order to quickly and easily provide a luminaire for the desired application conditions.

[0019] In this respect, a modular system is provided with the central element "gear tray," from which a multitude of different combinations are possible to create a wide variety of luminaires. This eliminates the need to construct each luminaire individually; instead, they can be assembled directly by attaching the "housing" and "light emitting element" modules to the gear tray.

[0020] The modular system can also be easily expanded, for example with additional housings and / or light emitting elements, where essentially during their provision or construction it is only necessary to ensure that they are provided with interface sections that fit the receiving sections of the device carrier.

[0021] Preferably, the set of housings further comprises more than two differently designed housings, preferably between 3 and 20.

[0022] Preferably, the number of light-emitting elements further comprises more than two differently designed light-emitting elements, preferably between 3 and 20.

[0023] In a preferred embodiment, the first receiving section of the device carrier and the first interface sections of the light emitting elements of the set of light emitting elements are designed in such a way that, in the assembled state of the modular luminaire, a positive and / or non-positive fastening of the light emitting element to the device carrier is implemented, in particular without the use of additional fastening means, such as screws, bolts, nuts, or the like.

[0024] This allows for reliable and precise fastening.

[0025] In a preferred embodiment, the first receiving section of the device carrier and the first interface sections of the light-emitting elements of the set of light-emitting elements are designed such that the positive and / or non-positive fastening can be released and / or produced by elastic deformation of the first interface section and / or the first receiving section.

[0026] This makes it possible to make and / or remove the fastening, preferably without additional tools, so that a modular luminaire can be assembled or disassembled quickly and easily.

[0027] In a preferred embodiment, the first receiving section of the device carrier and the first interface sections of the light-emitting elements of the set of light-emitting elements are designed to form a latching engagement, in which an engagement groove of the first receiving section engages in a latch of the first interface section.

[0028] In an alternative embodiment, an engagement groove of the first interface section engages in a catch of the first receiving section.

[0029] The locking engagement is easy to manufacture and simultaneously provides a robust, thus reliable and secure fastening. In a preferred embodiment, the second receiving section of the device carrier and the second interface sections of the housings of the set of housings are designed in such a way that, when the modular luminaire is assembled, they enable a positive and / or force-fitting fastening of the housing to the device carrier.

[0030] In a preferred embodiment, the housings of the set of housings and the light emitting elements of the set of light emitting elements are adapted to one another and to the device carrier in such a way that the housing and the light emitting element, in the assembled state of the modular luminaire, define an interior space in which the device carrier is arranged.

[0031] Preferably, the interior is partially or completely closed off from the surroundings of the assembled modular luminaire.

[0032] In the assembled state, there is an interior space that is preferably closed off from the environment, in which the device carrier and preferably also all electrical components attached to it are arranged.

[0033] These components can include a light source, energy storage devices, radio modules, converters, transformers, feeders, control units, or similar components used to operate the luminaire. By arranging them indoors, these components are separated from the environment and can thus be protected from contamination, for example. The risk of injury is also minimized, as the components are inaccessible or at least difficult to access from the environment.

[0034] In a preferred embodiment, each housing of the set of housings has a first contact portion, and each light-emitting element of the set of light-emitting elements has a second contact portion, wherein the first and second contact portions are adapted to one another in such a way that, in the assembled state of the modular luminaire, they terminate in contact with one another in order to delimit the interior space.

[0035] In a preferred embodiment, the first and second contact sections are adapted to one another in such a way that they form a tongue and groove connection in the assembled state of the modular luminaire.

[0036] The tongue-and-groove connection allows for an easy-to-implement and stable connection between the housing and the light emitting element. Assembly is also simplified, as the components are guided relative to each other by inserting the tongue into the groove.

[0037] In a preferred embodiment, to form the tongue-and-groove connection, each first contact section comprises a tongue, and each second contact section comprises a groove adapted to the tongue. Alternatively, each second contact section can also comprise a tongue, and each first contact section can comprise a groove adapted to the tongue.

[0038] In a preferred embodiment, the first and second contact sections are adapted to one another in such a way that a tongue and groove connection extends along a large part of an outer circumference of the device carrier, in particular along the entire outer circumference.

[0039] The tongue and groove connection preferably extends over 50%, more preferably over 75% and particularly preferably over 90% or 100% of the outer circumference of the device carrier.

[0040] This allows for a complete or at least almost complete closure of the housing and light emitting element, which improves guidance during assembly of the luminaire and also enables an improved closure of the interior from the surroundings.

[0041] In a preferred embodiment, the housings of the set of housings each comprise a sealing element in the region of the first contact section, which, in the assembled state of the modular luminaire, is in contact with the second contact section of the light emitting element such that a gap between the first and the second contact section is sealed.

[0042] Additionally or alternatively, the light emitting elements of the set of light emitting elements each comprise a sealing element in the region of the second contact section, which, in the assembled state of the modular luminaire, is in contact with the first contact section of the housing such that a gap between the first and the second contact section is sealed.

[0043] In a preferred embodiment, the sealing elements are arranged in the assembled state of the modular luminaire between the tongue and groove of the formed tongue and groove connection, wherein in particular the tongue has a tapered end section which is pressed into the sealing element in the assembled state of the modular luminaire.

[0044] By using the sealing element, the interior can be separated even better from the surroundings of the luminaire and can thus, for example, prevent or at least further reduce the penetration of moisture through the interface of the tongue and groove connection.

[0045] In a preferred embodiment, the lighting kit comprises a light source attached to the device carrier, which is in particular an LED or an LED module.

[0046] This provides a particularly energy-saving light source, with a composite modular luminaire additionally comprising the attached light source. The LED module preferably comprises a printed circuit board or printed circuit board with a plurality of LEDs arranged thereon.

[0047] In a preferred embodiment, the device carrier and each of the light emitting elements of the set of light emitting elements are adapted to one another in such a way that, in the assembled state of the modular luminaire, they define a luminaire space between them in which the luminous means fastened to the device carrier is arranged.

[0048] In a preferred embodiment, the first receiving section of the device carrier comprises a first and a second partial section, between which the attached illuminant is arranged.

[0049] Preferably, the first interface sections also have a first and a second subsection, which are each adapted to the first and second subsection of the first receiving section.

[0050] This enables a symmetrical design in which the light-emitting element is mounted on both sides of the lamp in the corresponding sections of the first mounting section. This improves the mounting and also ensures, for example, more uniform illumination from the lamp.

[0051] Preferably, the partial sections of the first receiving section each extend along a majority of the sides of the device carrier which each extend in a longitudinal direction of the device carrier.

[0052] Preferably, a length of one and / or both partial sections of the first receiving section is at least 50% of a length of the device carrier in its longitudinal direction, more preferably at least 60%, more preferably at least 70% and particularly preferably at least 80%, 90% or 100%.

[0053] This improves the absorption of the light emitting element and creates a more stable and resilient attachment.

[0054] In a preferred embodiment, at least one light-emitting element of the set of light-emitting elements, in particular each light-emitting element of the set of light-emitting elements, is an element from the following group, comprising a light guide, a cavity box, a light box, a diffuser element, a cover element, or a lens.

[0055] Depending on the application, a variety of possible light emitting elements is provided, whereby the possible light emitting elements should not be understood as being limited to the above list.

[0056] In a preferred embodiment, the set of light-emitting elements comprises at least two identical light-emitting elements which differ in at least one of their dimensions, preferably different lengths and / or different widths and / or different heights.

[0057] Preferably, the set of light emitting elements comprises at least two light guides which have different lengths along a main emission direction of the modular luminaire, and / or the set of light emitting elements comprises at least two cavity boxes which have different lengths along a main emission direction of the modular luminaire.

[0058] In a preferred embodiment, at least one housing of the set of housings meets an IP protection class, in particular IP protection class 65.

[0059] This means that a luminaire for use in more extreme environments can also be put together based on the luminaire kit, for example for use in damp rooms or outdoor areas.

[0060] In a preferred embodiment, the luminaire kit is an escape route luminaire kit for providing a modular escape route luminaire, wherein at least one light emitting element (preferably all light emitting elements) of the set of light emitting elements has an escape route indicator.

[0061] The escape route indicator can be designed as a symbol, lettering, emblem or the like, preferably printed, glued, painted or incorporated into a surface of the light emitting element, wherein the escape route indicator is illuminated in particular by light from the illuminant.

[0062] In a preferred embodiment, the luminaire kit is an emergency lighting luminaire kit for providing a modular emergency lighting luminaire, wherein the emergency lighting luminaire kit preferably comprises an electrical energy storage device, such as a battery or an accumulator, which is configured as part of a modular emergency lighting luminaire to supply it with electrical energy.

[0063] In this way, lights can be provided that can be operated independently of an external power supply and whose function is guaranteed, especially in the event of a power failure.

[0064] In a preferred embodiment, the luminaire kit further comprises a set of escape route illumination elements, which in turn comprise one or more escape route illumination elements, such as an ERI lens.

[0065] The abbreviation ERI stands for “Escape Route Illumination”.

[0066] In this respect, in addition to the light emitting element, which, for example, carries an escape route indicator, the escape route itself can also be illuminated to better guide escaping persons. The multiple escape route illumination elements are preferably designed differently, but can also be designed identically.

[0067] In a preferred embodiment, at least one housing of the set of housings comprises one or more ERI receptacles for respectively receiving an escape route illumination element from the set of escape route illumination elements.

[0068] Alternatively or additionally, at least one light-emitting element of the set of light-emitting elements comprises one or more ERI receptacles for the respective recording of an escape route illumination element from the set of escape route illumination elements.

[0069] In this way, the escape route illumination elements can be accommodated on the light emitting elements and / or on the housing, each of which preferably comprises at least 2, more preferably at least 3 and particularly preferably at least 4 ERI receptacles.

[0070] Preferably, at least one escape route illumination element of the set of escape route illumination elements comprises a separate illuminant.

[0073] Preferably, the luminaire kit further comprises a set of closure elements adapted to the ERI receptacles in order to close them.

[0074] This allows the ERI receptacles to be closed if an assembled modular luminaire, whose housing and / or light emitting element has ERI receptacles, is not to be equipped with escape route illumination elements.

[0075] In a preferred embodiment, the set of escape route illumination elements comprises at least one escape route illumination element with a fixed radiation direction and / or one escape route illumination element with an adjustable radiation direction.

[0088] Detailed character description

[0089] Figs. 1A and 1B show a section through a first exemplary modular luminaire 1000a, which was assembled based on an exemplary embodiment of the luminaire kit according to the invention. Fig. 1A shows a perspective view of the luminaire 1000a cut orthogonally to a longitudinal direction x, and Fig. 1B shows an enlarged section of the cut surface.

[0090] Fig. 1A and 1B are described together below.

[0091] The illustrated luminaire 1000a consists of at least a device carrier 10, a light emitting element 20a received on the device carrier 10 and a housing 30a received on the device carrier 10, all of which are components of the luminaire kit.

[0092] The device carrier 10 comprises a first receiving section 101 for receiving the light emitting element 20a and a second receiving section (not shown) for receiving the housing 30a.

[0093] For this purpose, the light-emitting element 20a comprises a first interface section 201, which is adapted to the first receiving section 101 of the device carrier 10, and the housing 30a comprises a second interface section (not shown) which is adapted to the second receiving section of the device carrier 10. The first receiving section 101 of the device carrier 10 preferably has a first and a second subsection, each of which is arranged on one of the sides of the device carrier 10 extending in the longitudinal direction x (in Fig. 1B, on a right and left side of the device carrier 10, respectively).

[0094] Accordingly, the first interface section 201 of the light emitting element 20a also has a first and a second subsection, which are each adapted to the first and second subsection of the first receiving section 101 of the device carrier 10 (in Fig. 1B on a right and left side of the light emitting element 20a).

[0095] The light emitting element 20a is selected from a set of light emitting elements (not shown) which comprises at least two differently designed light emitting elements, wherein each light emitting element comprises a respective first interface section which is adapted to the first receiving section 101 of the device carrier 10.

[0096] The housing 30a is selected from a set of housings (not shown) comprising at least two differently designed housings, each housing comprising a respective second interface section which is adapted to the second receiving section of the device carrier 10.

[0097] In the received state, the first interface section 201 of the light emitting element 20a interacts with the first receiving section 101 of the device carrier 10, preferably in a force-locking and / or form-locking manner.

[0098] Furthermore, in the received state, the second interface section of the housing 30a interacts with the second receiving section of the device carrier 10, preferably in a force-locking and / or form-locking manner.

[0099] The fastening of the light emitting element 20a to the device carrier 10 is preferably carried out via a locking engagement, in which a right and a left engagement groove of the first interface section 201 engages in a respective notch of the first receiving section 101, which here are preferably designed to protrude outwards (see Fig. 1B).

[0100] The first receiving section 101 or its subsections preferably extend at least partially along a respective side of the device carrier 10 extending in the longitudinal direction x, particularly preferably along a major part of both sides of the device carrier 10 extending in the longitudinal direction x.

[0101] In the assembled state of the luminaire 1000a, the housing 30a and the light-emitting element 20a preferably define an interior space in which the device carrier 10 is arranged. In other words, the device carrier 10 is preferably at least partially enclosed by the housing 30a and the light-emitting element 20a. The housing 30a preferably has a first contact section with a groove 301, and the light-emitting element 20a preferably has a second contact section with a tongue 202 adapted to the groove 301. In the assembled state of the luminaire 1000a, the groove 301 and the tongue 202 form a tongue-and-groove connection NF with one another, thus preferably sealing off one another to delimit the interior space.

[0102] The tongue and groove connection NF preferably extends at least partially along a side of the device carrier 10 extending in the longitudinal direction x, particularly preferably along a major part of both sides of the device carrier 10 extending in the longitudinal direction x.

[0103] The housing 30a preferably comprises a sealing element 302 in the region of the first contact section or groove 301, which, in the assembled state of the luminaire 1000a, is in contact with the second contact section or tongue 202 of the light-emitting element 20a such that a gap between the first and second contact sections is sealed. The sealing element is preferably arranged between the groove 301 and tongue 202 of the tongue-and-groove connection NF.

[0104] Preferably, the spring 202 has a tapered end portion which is pressed into the sealing element 301 in the assembled state of the lamp 1000a.

[0105] By means of this construction with a sealed tongue and groove connection NF, the interior space, in which in particular the electrical components of the luminaire 301 are arranged, can be at least partially sealed off from the surroundings of the luminaire 1000a.

[0106] Particularly preferably, the tongue and groove connection NF with the sealing element 301 arranged therebetween extends along the entire outer circumference of the device carrier 10.

[0107] A light source 40 is preferably attached to the device carrier 10, which is designed in particular as an LED module and which is preferably arranged in the said interior of the lamp 1000a.

[0108] The device carrier 10 and the light-emitting element 20a are preferably adapted to one another in such a way that, in the assembled state of the luminaire 1000a, they define a luminaire chamber 50 between them, in which the illuminant 40 attached to the device carrier 10 is arranged. The illuminant 40 is preferably arranged such that it radiates into the luminaire chamber 50.

[0109] In the illustrated example of the first luminaire 1000a, the light-emitting element 20a selected from the set of light-emitting elements of the luminaire kit is preferably a cavity box 20a comprising side elements 203 and a base element 204, which preferably delimit the said luminaire space 50. At least one side element 203 preferably carries an escape route indicator 205, here in the form of an arrow, so that the luminaire 1000a shown can be an escape route luminaire.

[0110] During operation of the luminaire 1000a, the illuminant 40 preferably radiates into the luminaire chamber 205 and the light penetrates into the surroundings of the luminaire 1000a via the light emitting element 20a, in particular via the preferably transparent or semi-transparent side elements 203.

[0111] Figs. 2A and 2B show a section through a second exemplary modular luminaire 1000b, which was assembled based on an embodiment of the luminaire kit according to the invention. Fig. 2A shows a perspective view of the luminaire 1000b cut orthogonally to a longitudinal direction x, and Fig. 2B shows an enlarged section of the cut surface.

[0112] Figs. 2A and 2B are described together below.

[0113] The illustrated luminaire 1000b is composed of at least a device carrier 10, a light emitting element 21a received on the device carrier 10 and a housing 30a received on the device carrier 10, all of which are components of the luminaire kit.

[0114] The structure of the second luminaire 1000b is largely similar to that of the first luminaire 1000a shown in Figs. 1A and 1B. Therefore, a repeated description of the essentially identical features will be omitted here.

[0115] As in the case of the first luminaire 1000a of Figs. 1A and 1B, the device carrier 10 comprises a first receiving portion 101 for receiving the light emitting element 21a and a second receiving portion (not shown) for receiving the housing 30a.

[0116] For this purpose, the light emitting element 21a comprises a first interface section 201 which is adapted to the first receiving section 101 of the device carrier 10, and the housing 30a comprises a second interface section (not shown) which is adapted to the second receiving section of the device carrier 10.

[0117] The first receiving section 101 of the device carrier 10 preferably has a first and a second subsection, each of which is arranged on one of the sides of the device carrier 10 extending in the longitudinal direction x (in Figs. 2A and 2B on a right and left side of the device carrier 10, respectively).

[0118] Accordingly, the first interface section 201 of the light-emitting element 21a also has a first and second subsection, which are each adapted to the first and second subsections of the first receiving section 101 of the device carrier 10 (in Figs. 2A and 2B, on a right and left side of the light-emitting element 21a, respectively).
