Description

[0001] The invention relates to a signal light for a technical device and to a technical device with such a signal light.

[0002] Signal lights are designed to provide information about the status of a technical device. They typically emit light in different colors. For example, a trouble-free operating state can be indicated with green light, a maintenance state with yellow light, and a malfunction state with red light.

[0003] Such signal lights are known in a wide variety of designs. In particular, there are signal lights that are very flat, allowing them to be integrated well into the appearance of a technical device not only from an aesthetic point of view, but also advantageous in terms of their installation space requirements. Signal lights that protrude far beyond the contour of a technical device can thus be avoided, and the associated risk of accidents can be reduced accordingly. Examples include the signal lights known from DE 2017 204 011 A1 or EP 4 336 154 A2.

[0004] To achieve sufficient visibility of the light emitted by the signal lamp despite its flat design, existing systems attempt to provide the largest possible illuminated area. This is achieved through the use of fiber optics and / or relatively long light strips. Such systems therefore involve comparatively high component costs and installation effort.

[0005] The invention therefore aims to provide a signal light that is flat in design, offers good visibility, and is also cost-effective to manufacture. The invention further aims to provide a technical device with a corresponding signal light.

[0006] The problems are solved according to the invention by a signal light with the features of claim 1 and a technical device with the features of claim 13.

[0007] Advantageous embodiments and further developments of the invention are specified in the dependent claims.

[0008] A signal lamp according to the invention for a technical device comprises a housing shell and a light source arranged in the housing shell, wherein the housing shell has a shell opening and a rim surrounding the shell opening with at least one contact section and at least one exit section. The at least one exit section is set back relative to the at least one contact section. Preferably, the at least one exit section is set back relative to the at least one contact section towards the housing shell. Preferably, the housing of the signal lamp comprises exclusively the housing shell.

[0009] The signal light is preferably designed to be mounted, along with at least one system section, on an external wall not belonging to the signal light itself. This external wall could, for example, be an outer wall of the technical device. Alternatively, the signal light housing could include a cover that at least partially closes the opening. In this case, the cover and / or the at least one system section could be designed to be mounted on the external wall.

[0010] Because the at least one outlet section is set back from the at least one system section, an outlet opening can be formed in the area of ​​the at least one outlet section between the housing shell and the external wall, through which light emitted by the light source can exit the signal lamp. The signal lamp is thus designed such that the light emitted by the light source can exit the signal lamp directly at the external wall. The light exiting the signal lamp can therefore be scattered and / or reflected at the external wall, which allows good visibility to be achieved with simple means in a flat design of the signal lamp. In particular, the signal lamp is preferably free of additional light guides.

[0011] Preferably, the at least one system section is arranged entirely within exactly one system plane. Particularly preferably, each of the at least one system section is arranged in the same system plane. This makes the signal light particularly suitable for mounting against a flat external wall. The at least one outlet section is preferably set back from the system plane towards the housing shell. Preferably, the shell opening is arranged within the system plane.

[0012] The at least one outlet section can be arranged parallel to the at least one system section. This allows the outlet opening to be slot-shaped when the signal light is attached to the external wall in the area of ​​the at least one outlet section.

[0013] In a preferred embodiment of the invention, the edge has several outlet sections. Each of the outlet sections preferably has the features of the at least one outlet section described above. Because the edge is formed circumferentially, the existence of several outlet sections implies that the edge has several contact sections. Each of the outlet sections preferably has the features of the at least one outlet section described above.

[0014] The shell opening can essentially be designed as a polygon with multiple sides. The term "essentially" here and in the following refers in particular to the fact that the corners of the polygon can be rounded and / or the sides of the polygon can be straight and / or curved.

[0015] Preferably, each of the emission sections is arranged on exactly one of the sides of the polygon. Preferably, at most one of the emission sections is arranged on each of the sides. This allows, in particular, the light emitted from the signal lamp to be visible from multiple directions.

[0016] In a particularly preferred embodiment of the invention, the opening of the housing is essentially triangular, preferably a right-angled triangle. This allows the signal light to be advantageously positioned at an upper corner of the technical device. Since the upper corner of the technical device is often right-angled, a signal light with a right-angled triangular opening can be particularly advantageous for placement at the upper corner of the technical device.

[0017] Preferably, the rim has a first exit section and a second exit section, the first exit section being located on a first side of the triangle and the second exit section on a second side of the triangle. If the shell opening is designed as a right-angled triangle with two legs and a hypotenuse, the first exit section is preferably located on the hypotenuse and the second exit section on one of the legs. When the signal lamp is positioned at a right-angled corner of the device, this allows for direct visibility of the light emitted from the signal lamp from three directions using two exit openings. The first exit section and the second exit section preferably have the features of the exit sections described above.

[0018] The light source can be designed as a light strip fitted with LEDs on both sides. This allows sufficient light emission from each of the multiple emission openings, particularly those located on different sides of the housing shell. Preferably, the light strip is rigid. The light strip can be designed as a printed circuit board. Preferably, the signal light has exactly one light source.

[0019] Preferably, the luminous strip is arranged parallel to one of the at least one exit section. For example, the luminous strip can be arranged parallel to the first exit section located on the hypotenuse of the shell opening. Preferably, the light exiting the at least one exit section can be influenced by the arrangement of the luminous strip relative to the at least one exit section. Therefore, embodiments are also conceivable in which the luminous strip is arranged non-parallel to the at least one exit section, in particular non-parallel to the hypotenuse.

[0020] In a further development of the invention, the housing shell has an inner surface that is light-tight and / or reflective. A light-tight inner surface prevents the light emitted by the light source from interfering with information displayed on the outer surface of the housing shell. A reflective inner surface reduces the proportion of light emitted by the light source that is absorbed by the housing shell. In particular, a light-tight and / or reflective coating can be applied to the inner surface of the housing shell.

[0021] The housing shell can have an outer shell and an inner shell, with the light source preferably arranged in the inner shell. This allows for a modular design of the signal light, so that, for example, the inner shell could be combined with different outer shells. Preferably, the inner shell is light-tight and / or reflective. Particularly preferably, the inner shell is made of a light-tight and / or reflective material.

[0022] A technical device according to the invention comprises an outer wall and the signal lamp described above, wherein the signal lamp is arranged on the technical device such that the at least one discharge section is located on the outer wall. Preferably, the signal lamp is arranged directly on an outer surface of the outer wall. The outer wall is preferably planar, so that a slot-shaped discharge opening is formed between the outer wall and the at least one discharge section. The signal lamp is particularly preferably arranged at an upper corner of an outer wall of the technical device. Here and in the following, the term "outer wall" preferably refers to vertically arranged sections of the outer wall. If the opening of the shell is designed as a right-angled triangle, the two legs are preferably arranged parallel to two mutually perpendicular edges of the outer wall.

[0023] Preferably, the outer wall is white and / or reflective. On a reflective outer wall, the light exiting through the aperture can be scattered, thus achieving particularly good indirect visibility of the exiting light. Against a white outer wall, the color of the light exiting through the aperture can be perceived unchanged.

[0024] In a preferred embodiment of the invention, the technical device is designed as a simulation cabinet, particularly preferably as a climate cabinet.

[0025] An embodiment of the invention is explained with reference to the following figures. It shows: Figure 1 is a schematic front view of an embodiment of a signal light, Figure 2 is a schematic rear view of the in Fig. 2 The exemplary embodiment shown, Figure 3, is a schematic view of an exemplary embodiment of a simulation cabinet with the in Fig. 1 u. 2 signal light shown.

[0026] The Figuren 1 bis 3 These figures show different views of various embodiments. For clarity, not all reference numerals are used in every figure. The same reference numerals are used for identical and functionally equivalent parts.

[0027] Fig. 1 Figure 1 shows a front view of an embodiment of a signal light 10 for a technical device. Due to the chosen view, in Fig. 1 Only one housing shell 12 of the signal light 10 is visible. Preferably, one housing of the signal light 10 comprises exclusively the housing shell 12.

[0028] The Fig. 2 rear view of the depicted in Fig. 1 The illustrated embodiment shows that a light source 14 is arranged in the housing shell 12. The view in also shows Fig. 2 The housing shell 12 has a shell opening 16 and a rim 18 surrounding the shell opening 16. The rim 18 preferably has two contact sections 20 as well as a first outlet section 22 and a second outlet section 24, wherein the two outlet sections 22, 24 are set back from the housing shell 12 relative to the contact sections 20.

[0029] Preferably, the plant sections 20 are arranged entirely in exactly one plant level 26, which is in Fig. 2 as shown in outline. This makes the signal light 10 particularly suitable for mounting on a flat external wall. The two outlet sections 22, 24 are preferably set back from the mounting surface 26 towards the housing shell 12. The first outlet section 22 and the second outlet section 24 can each be arranged parallel to the mounting sections 20. Fig. 2 This also shows that the shell opening 16 is preferably arranged in the plane 26.

[0030] Fig. 2 Figure 1 shows that the shell opening 16 is preferably formed essentially as a right-angled triangle with three sides 28, namely two legs 30 and a hypotenuse 32. Accordingly, the shell opening 16 preferably has three corners 34, which may be rounded. Preferably, the first outlet section 22 is arranged on the hypotenuse 32 and the second outlet section 24 on one of the legs 30.

[0031] How Fig. 2 Furthermore, as shown, the light source 14 can be designed as a luminous strip 38, equipped on both sides with LEDs 36 and configured as a circuit board 37. It is particularly preferred that the luminous strip 38 be arranged parallel to the first exit section 22 located on the hypotenuse 32 of the shell opening 16.

[0032] The housing shell 12 can have an outer shell 40 and an inner shell 42. While in Fig. 1 only the outer shell 40 is visible, shows Fig. 2 The inner shell 42 is arranged in the outer shell 40, and the light source 14 is preferably arranged in the inner shell 42. Preferably, the inner shell 42 is light-tight and reflective, so that an inner surface 43 of the housing shell 12 is light-tight and reflective. Due to the light-tightness of the inner shell 42, interference with information 44 arranged on the outer shell 40 by the light emitted by the light source 14 can be avoided. Due to the reflective property of the inner shell 42, the proportion of the light emitted by the light source 14 that is absorbed by the housing shell 12 can be reduced.

[0033] In Fig. 3 A technical device 46, namely a simulation cabinet 48, is shown with an outer wall 52 and a signal light 10. The signal light 10 can be arranged on an outer wall 52 of the simulation cabinet 48 such that the system sections 20 are arranged directly on the outer wall 52.

[0034] In the area of ​​the signal light 10, the outer wall 52 is preferably flat. In combination with the parallel arrangement of the outlet sections 22, 24 to the system sections 20, a slot-shaped outlet opening 54 can be formed between the outer wall 52 of the simulation cabinet 48 and each of the two outlet sections 22, 24. Light emitted by the light source 14 can exit the signal light 10 directly through the outlet openings 54 at the outer wall 52 of the simulation cabinet 48. The light exiting the signal light 10 can thus be scattered and / or reflected at the outer wall 52, which, with a flat design of the signal light 10, ensures good visibility of the exiting light.

[0035] As the Fig. 3 As shown, the signal light 10 is particularly preferably arranged at an upper corner 56 of the outer wall 52, such that the two legs 30 are each arranged parallel to two edges 58 of the outer wall 52 arranged at right angles to each other. In the Fig. 3 In the illustrated embodiment, the light exiting the signal lamp 10 in the first exit section 22, which is arranged on the hypotenuse 32, is visible from below and to the right. The second exit section 24 is preferably arranged on a vertical side of the edges 58. Thus, in the illustration of the Fig. 3 The light emanating from signal lamp 10 is also visible from the left. Overall, such an arrangement with the two emission openings 54 allows the light emanating from signal lamp 10 to be directly visible from three directions.

[0036] The outer wall 52 of the in Fig. 3The simulation chamber 48 shown is preferably white and reflective. This allows for good diffusion of the light exiting through the aperture 54 without altering its hue. In particular, this ensures good indirect visibility of the emitted light and accurate perception of the information content associated with the hue. Reference symbol list
