Abstract

The invention relates to a lighting device for the direct, preferably directed, illumination of an area, preferably a kitchen work area, comprising an elongate support device, at least two light sources arranged on the support device and a fastening device for the height-adjustable fastening of the support device to a ceiling.

Description

[0001] The invention relates to a lighting device for directly illuminating an area, preferably a kitchen work area.

[0002] Such lighting devices are generally known as spots, for example.

[0003] The disadvantage is that these spots have to be individually adjusted to optimally illuminate the area, which is often not possible or is comparatively time-consuming.

[0004] It is therefore an object of the invention to improve a lighting device of the type mentioned at the outset in such a way that it always optimally illuminates the area with simple installation.

[0005] The solution to this problem is provided by the subject matter of the independent claim.

[0006] According to the invention, the lighting device is designed and / or can be used for directly illuminating an area.

[0007] The area may preferably be a work area, e.g. a kitchen work area, a work surface and / or a worktop, e.g. a kitchen worktop.

[0008] Preferably, the lighting device is a kitchen lighting device.

[0009] Preferably, lighting is directed, e.g., using point light sources. Directed light, also known as focused light, is a special case of direct lighting in which the emitted light is directed and / or focused onto a relatively small or narrow area. While the surrounding area is not illuminated and therefore appears darker, the area hit by the directed light is illuminated and thus emphasized. This creates a relatively strong separation between light and shadow, resulting in a visually appealing effect.

[0010] For example, fluorescent tubes and / or neon tubes produce diffuse rather than directed light.

[0011] This can be optimized during production. The lighting fixture only needs to be hung at the customer's location to achieve optimal illumination, preferably with directed light.

[0012] The lighting device has an elongated support device.

[0013] Preferably, the support device is oriented parallel to the area, to a work surface and / or to the ceiling when mounted.

[0014] The lighting device has at least two light sources arranged on the support device.

[0015] The light sources illuminate the area directly, preferably in a directed manner.

[0016] For example, the light sources are spaced apart from each other.

[0017] Preferably, the light sources are arranged at different positions of the support device with respect to the longitudinal direction of the support device, e.g. left, right and / or central.

[0018] Preferably, all light sources are arranged on one side, preferably the underside, of the support device.

[0019] For example, when mounted, the light sources are at the same height relative to the area or work surface.

[0020] Finally, the lighting device has a fastening device for height-adjustable fastening of the support device to a ceiling.

[0021] During installation, for example, you only need to adjust the desired height to achieve optimal, preferably directed, lighting.

[0022] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

[0023] According to one embodiment, at least or exactly three light sources are arranged on the support device.

[0024] For example, one light source can be positioned centrally and two additional light sources can be positioned at each of the lateral end areas of the support device. This allows for optimal lighting.

[0025] The light sources can, for example, be spaced apart from each other, e.g. equidistant.

[0026] Preferably, all light sources are arranged on one side, preferably the underside, of the support device.

[0027] For example, when mounted, the light sources are at the same height relative to the area or work surface.

[0028] According to a further embodiment, each light source has several, preferably at least or exactly two, three, four, five, six or more, light units.

[0029] The more lighting units are provided, the more light can be emitted.

[0030] The lighting units can be LEDs, for example.

[0031] Preferably, exactly three light sources with exactly four light units per light source are provided.

[0032] According to a further embodiment, the respective light exit angles of the lighting units of the same light source are the same.

[0033] The light units of a light source therefore point in the same direction or to a common area.

[0034] Alternatively or additionally, the respective light emission angles of the lighting units of different light sources are different.

[0035] The light units of the different light sources point in different directions. Preferably, they can be directed at a common area to optimally illuminate it.

[0036] According to a further embodiment, the support device has a groove, preferably U-shaped or V-shaped, on a side facing away from the light sources.

[0037] The groove is preferably provided on the top side of the support device.

[0038] For example, the groove extends at least partially over the length of the support device. Preferably, the groove extends over the entire length of the support device, possibly except for possible end closures.

[0039] Glasses, such as spice jars, can be placed in the groove. Preferably, the outer contour of the jars can be adapted to the shape of the groove. This allows the jars to be easily integrated and / or placed in a manner that is dimensionally stable, for example. Preferably, the jars do not come loose accidentally.

[0040] Alternatively or additionally, cooking utensils such as ladles, spoons, pans, whisks, or the like can be hung. Preferably, the outer contour of an end portion, e.g., a hook, of the cooking utensil can be adapted to the shape of the groove. For example, the end portion of a handle can be shaped accordingly. The cooking utensils can thus be hung easily, for example, in a dimensionally stable manner. Preferably, the cooking utensils do not become accidentally detached.

[0041] According to a further embodiment, the fastening device has at least one ceiling suspension for fastening the support device to the ceiling.

[0042] For example, several, e.g. at least or exactly two, three, four, five, six or more, ceiling suspensions can be provided.

[0043] Preferably, two ceiling suspensions can be arranged in a V-shape relative to each other, or one ceiling suspension can be V-shaped. This enables a stable attachment.

[0044] The ceiling suspension can, for example, be designed as a rigid rod. This can optionally have a power cable inside. The length of the rod is preferably fixed. However, a telescopic rod is also conceivable.

[0045] Alternatively or additionally, a cable, a cord, a rope, a wire and / or a chain is conceivable.

[0046] Preferably, a kit with ceiling suspensions of different lengths can be provided. The length of the ceiling suspension can be selected based on the ceiling height.

[0047] For example, at least one or more cables, cords, ropes, wires, and / or chains can be optionally provided as an additional ceiling suspension. The additional ceiling suspension supports the lighting fixture, for example, from the sides. This can prevent unwanted lateral swinging. Furthermore, the light sources can be supplied with power via the additional ceiling suspension. Several, e.g., two, additional ceiling suspensions can also be provided.

[0048] Preferably, the additional ceiling suspension is mounted decentrally and / or asymmetrically on the support structure, e.g., according to the golden ratio. This is visually appealing. Alternatively, a central and / or symmetrical attachment to the support structure is conceivable.

[0049] According to a further embodiment, the fastening device has an elongated base with a longitudinally extending guide rail.

[0050] Preferably, the base is oriented parallel to the support device, the area, the work surface and / or the ceiling when mounted.

[0051] Preferably, the base is shorter than the support device.

[0052] Preferably, at least one or exactly one ceiling suspension is arranged at each end region of the base. For example, exactly two ceiling suspensions are arranged at each end region of the base.

[0053] The ceiling suspension can, for example, be screwed to the base.

[0054] Alternatively, the base can be suspended from the ceiling suspension. For this purpose, the ceiling suspension can be V-shaped, for example. For example, the base can have a notch, e.g., in the area of ​​the guide rail. The ceiling suspension can then be threaded through the guide rail and lock into place at the notch.

[0055] According to a further embodiment, the fastening device has at least one fixing device movable along the slotted guide.

[0056] The fixing device can be designed as a roller, for example, or comprise a roller. For example, the roller can be divided into two parts, with an intermediate piece connecting the roller parts, e.g., an axle, being arranged within the guide rail.

[0057] Preferably, two fixing devices are provided. These are arranged, for example, in the same guide rail.

[0058] According to a further embodiment, the fixing device can be fixed to the guide rail.

[0059] For this purpose, the fixing device can, for example, have a thread. The thread can be used to screw the roller parts together in such a way that the fixing device adheres to the guide rail at a desired position.

[0060] According to a further embodiment, the fastening device has at least one connecting element which is connected to the supporting device and the fixing device.

[0061] Preferably, the connecting element is articulated to the support device and / or the fixing device.

[0062] The connecting element can, for example, be designed as a rigid rod. The length of the rod is preferably fixed. However, a telescopic rod is also conceivable.

[0063] Alternatively or additionally, a cable, a cord, a rope, a wire and / or a chain is conceivable.

[0064] The connecting element connects the support device with the fixing device.

[0065] If the fixing device is moved, the height of the support device changes due to the positive guide. Once the desired height is reached, the fixing device can be locked. This allows for fine adjustment of the height setting. For example, the distance between the area and the lower edge of the support device and / or the optimal distance for the directed light can be adjusted. Protection is also claimed for this method of assembly and / or height adjustment.

[0066] Preferably, several, e.g. at least or exactly two, three, four, five, six or more, connecting elements can be provided.

[0067] Preferably, at least one or exactly one connecting element is arranged at each end region of the support device. For example, exactly two connecting elements are arranged at each end region of the support device. This enables a stable attachment.

[0068] The support device, the base and the connecting elements are preferably arranged in a trapezoidal shape.

[0069] For example, the connecting elements can be of equal length. This allows the base to be positioned centrally above the support structure.

[0070] Preferably, however, the connecting elements arranged at the different end areas are of different lengths. This allows the base to be positioned above the support structure according to the golden ratio. This is visually appealing.

[0071] All aspects, embodiments, and features of the invention described here can be combined with each other, preferably independently of the specific embodiment in which they are mentioned. Preferably, all subject matter of the dependent claims can be combined with each other and with the subject matter of the independent claim.

[0072] In general, it should be noted that terms like "a" or "an" do not necessarily mean "exactly one" or "exactly one," although this is also possible. The terms "a" or "an" can therefore be understood as "at least or exactly one" or "at least or exactly one." The use of the singular preferably includes the presence of the components in the plural, and vice versa.

[0073] It is noted that "vorzugsweise" and "vorzugt" can be translated into English as "preferably." A feature introduced by "vorzugsweise" or "vorzugt" is purely optional, can be omitted, and does not constitute a limitation, for example, of the claims.

[0074] The invention is described below by way of example with reference to the drawings. Fig. 1 a front view of an embodiment of a lighting device according to the invention, Fig. 2 a perspective view of the lighting device according to Fig. 1, Fig. 3 a detailed view of the lighting device according to Fig. 1, Fig. 4 a detailed view of another embodiment of a lighting device according to the invention, Fig. 5 a perspective view of the lighting device according to Fig. 1, and Fig. 6 a plan view of the lighting device according to Fig. 1.

[0075] First, it should be noted that the illustrated embodiments are purely exemplary in nature. Individual features can be implemented not only in the combination shown, but also individually or in other technically feasible combinations. For example, the features of one embodiment can be combined arbitrarily with features of another embodiment. For example, the number and / or position of the light sources, light units, and / or fixing devices can vary. Furthermore, the number, position, and / or length of the ceiling suspensions, additional ceiling suspensions, and / or connecting elements can vary.

[0076] If a figure contains a reference symbol that is not explained in the immediately corresponding description, reference is made to the corresponding preceding or following explanations in the figure description. Thus, the same reference symbols are used for identical or comparable components in the figures and these are not explained again.

[0077] Fig. 1 shows a lighting device for direct, preferably directed, illumination of an area not shown, e.g. kitchen work area.

[0078] An elongated support device 10 is attached to a ceiling (not shown) via a fastening device 12.

[0079] The fastening device 12 has a plurality of connecting elements 14 designed as rods, an elongated base 16 with a slotted guide 18, two fixing devices 20 designed as rollers, a plurality of ceiling suspensions 22 designed as rods and an additional ceiling suspension 24 designed as a cable (shown in dashed lines).

[0080] The support device 10 is attached to the base 16 via the connecting elements 14.

[0081] The connecting elements 14 are of different lengths, resulting in a ratio according to the golden ratio.

[0082] The rollers 20 can be adjusted along the guide rail 18. Since the rollers 20 are connected to the connecting elements 14, the height of the support device 10 is also changed by the positive guide.

[0083] Once the desired height is reached, the rollers 20 can be fixed.

[0084] As in Fig. As can be seen in Figure 2, three light sources 26, each with four light units 28, are arranged on the underside of the support device 10.

[0085] The respective light exit angles of the lighting units 28 of the same light source 26 are the same, while the respective light exit angles of the lighting units 28 of different light sources 26 are different.

[0086] The lighting units 28 can preferably produce directed light.

[0087] Fig. 3 shows a detailed view.

[0088] The base 16 can optionally have, e.g. slot-shaped, passages 30 for the additional ceiling suspension 24.

[0089] The ceiling suspensions 22 are arranged in a V-shape and screwed to the base 16.

[0090] As in Fig. 4, the ceiling suspensions 22 can also be formed in one piece and, for example, lock into a notch 32 of the link guide 18.

[0091] In Fig. 5 and Fig. 6 it can be seen that a groove 34 can be provided on the upper side of the support device 10.

[0092] In this groove 34, for example, glasses and / or hooks of kitchen utensils can be accommodated and / or safely stored.

[0093] The lighting device can therefore fulfil a dual function.
