DETAILED DESCRIPTION OF THE INVENTION

[0029] Before embodiments will be explained in the following with reference to the attached drawings, it should be pointed out that elements and structures having the same effect are provided with the same reference numerals, so that the description thereof can be applied to one another.

[0030] FIG. 1a shows the signal light 10 having a housing 12 and lighting elements 14 embedded in the housing. In the present case, these may be arranged behind one or more transparent regions provided with the reference numeral 12d.

[0031] In the present case, the housing 12 has a U-shape or C-shape. This means that the housing 12 forms this C-shape in two dimensions, while the housing 12 has an elongated shape in a third dimension (length dimension, cf. arrow L). Apart from the cutout caused by the C-shape, the housing 12 thus has a cylindrical shape with the cutout 13. The cutout 13 may have a round region with or without an undercut, as can be clearly seen with reference to FIG. 1b.

[0032] FIG. 1b shows a top view of the signal device 10. As can be seen, the housing 12 and the transparent region 12d of the housing 12 extend in a U-shape around the cutout 13. Alternatively, the housing may also have a C-shape so that undercuts are formed at the locations 13h. The cutout 13 can thus have an undercut 13 h according to further embodiments, wherein this undercut 13 h is optional. This means that, according to embodiments, the housing 12 may have a C-shape or, according to alternative embodiments, also a U-shape. The housing 12 has a flexible region in one region of the cutout 13 or also in a plurality of regions of the cutout 13, This flexible region is provided with reference numeral 15. Due to the flexible region 15, it is possible for the two housing halves 12a and 12b to be movable at least in a limited region. The movement or deformation region is provided with reference numeral V. In the case of deformation of the housing 12 due to the spreading of the housing halves 12a and 12b around the region 15, an elastic deformation of the region 15 occurs so that, in response to the deformation, the force F is then exerted radially by the two housing halves 12a and 12b or the two legs 12a and 12b. This makes it possible for a clamping force to be applied radially on an element located in the cutout 13, such as a pipe. This makes it possible to generate clamping with a positive and/or non-positive connection.

[0033] According to embodiments, the deformation may also be used to introduce a pipe through the opening 130 between the two housing halves 12a and 12b and to hold it in the undercut region.

[0034] Starting from the top view from FIG. 1b, a pipe (not illustrated) thus extends into or out of the plane of the illustration. This means that the housing 12 is configured to be clamped on an elongate object extending along the longitudinal axis L. Advantageously, the elongate object has a shape adapted to the cutout 13, for example a round shape. This means that the elongate object may also have another shape, such as an angular shape, wherein the cutout 13 then advantageously likewise has a correspondingly angular shape. This makes it possible for the signal lamp 10 to be clamped to a pipe, for example a vertical pipe of a construction machine, working machine, agricultural machine, or a vehicle, solely on account of the shape. The housing 12 and the transparent region 12d and also the lighting elements 14 then extend around the pipe in the cutout 13. At this point, it should be noted that the round shape of the cutout 13 may also have in the bent-open state (cf. elastic deformation region V), while in a non-deformed state the cutout 13 may have an oval shape, for example.

[0035] Starting from this, the lighting elements 14, such as RBG LEDs or RGBW LEDs, extend in a circular manner around the clamping object. This advantageously has the effect that detection of the illumination signal is thus possible in a large emission range, in this case over 180 or even over 270. To drive the LEDs, the unit 10 may comprise a controller (not illustrated); the latter is used, e.g., to receive data bus signals, to decode the data bus signals, and for corresponding (individual) driving in the sense of converting the messages into color signals, text signals, or graphics signals. According to embodiments, the controller may differentiate between daytime and nighttime modes. Depending on this, it would be conceivable to control the brightness (or display in general) in order to optimize readability under all light conditions.

[0036] In this context, according to further embodiments, the signal light 10 may comprise a brightness sensor (not illustrated in the figures). This makes it possible to automatically adapt the brightness of the lighting elements 14, e.g. by the controller described above, to the ambient brightness and to improve the readability of the lighting elements 14. The power consumption of the signal light 10 may also be optimized by adapting the brightness of the lighting elements 14 to the ambient light conditions. Furthermore, the signal light 10 may comprise a temperature sensor (not illustrated in the figures), as a result of which the brightness of the lighting elements 14 may likewise be automatically adapted.

[0037] In the embodiment from FIGS. 1a and 1b, it was assumed that the transparent regions 12d are provided both at the lower and at the upper end of the cylinder, so that two lighting arrays with the lighting elements 14 are provided. This makes it possible to output the corresponding color signal both at the bottom and at the top or else to output different signals at the top and at the bottom. For example, only alarm signals (warning indications) with red may be signaled at the top and only ready signals (status indications) with green at the bottom. Obviously, a variation of the colors and also of the signal states is also possible. Alternatively, it is also conceivable for multicolor LEDs (RGB or RGBW LEDs, e.g. 100 RGB or RGBW LEDs) also to be used instead of single-color LEDs, so that a plurality of signal states may be signaled at the top or at the bottom via one and the same array. LEDs generally have the advantage of saving energy.

[0038] Alternatively or additionally, the cladding surface region 12m (see FIG. 1c) may also comprise one or more lighting elements or planar lighting elements 14, for example one or more single-color or multicolor LEDs (RGB or RGBW LEDs or LED arrays). For this purpose, the cladding surface region 12m is configured to be either completely transparent or at least partially transparent.

[0039] The different signal states are also possible via different flashing frequencies. Furthermore, it would also be conceivable for running lights to be conceivable in series by individually driving the plurality of lighting elements 14 in order to symbolize a waiting state, for example. Furthermore, lighting elements 14 may be used flexibly for fill levels, for example (individual driving). According to further embodiments, in addition to mere color signals, the unit 10 delivers specific messages tailored to the application context. Customers may use logos, images and texts and thus adapt the signal light to their requirements. The lighting elements 14 may thus be arranged as a type of matrix for displaying text or the like, advantageously in the central region of the signal device 10. For this purpose, this central region of the cylinder, i.e. the region between the lower and upper regions 12d, is likewise configured to be transparent.

[0040] According to further embodiments, it would also be conceivable for a plurality, i.e. more than the two arrays, to be provided as lighting elements.

[0041] As already explained above, the emission advantageously takes place in a large emission range (>120, >150, >180 or even >270). A ring-shaped lighting array or also a C-shaped or U-shaped lighting array is formed by this emission range.

[0042] At this point, it should be noted that the signal light 10 may also comprise communication means, e.g. radio communication means, such as Bluetooth, WLAN or the like, e.g, in order to receive from the outside, e.g. from a construction machine/working machine/agricultural machine or from a vehicle, the corresponding information to be displayed by color coding or to be displayed in general with the status indication. Of course, according to embodiments, it is also conceivable for a cable connection to the construction machine/working machine/agricultural machine or the vehicle to be established. In this respect, the status indication 10 may comprise an interface, in particular a cable interface for receiving data. According to further embodiments, electrical energy for operating the signal light and/or for charging a battery of the signal light may also be available via such an interface or this interface. According to embodiments, the signal light may obviously also be battery-operated or comprise other energy supply means.

[0043] According to further embodiments, an inclination sensor or position sensor (not illustrated in the figures) may be arranged in or on the signal light 10 in order to determine the arrangement of the signal light on the construction machine/working machine/agricultural machine or the vehicle in a horizontal or vertical position. A change in position or orientation of the signal light 10 may also be detected with the inclination sensor or position sensor. If the signal light 10 comprises a matrix, as described above, for displaying logos, images or texts, it is possible, e.g. with a rotation of the signal light 10 by 90, to automatically adapt the displayed content (e.g., an image or a text) to the new position/orientation.

[0044] Alternatively or in addition to the above-described clamping of the housing 12 by positive and/or non-positive connection, it is possible to fasten the signal light 10 to a construction machine/working machine/agricultural machine or to a vehicle by means of a screw connection. To this end, the housing 12 comprises corresponding means for fastening the signal light 10, e.g., in the region of the cutout 13 or the opening 130. The means for fastening may be threaded bores, threaded sleeves, threaded inserts, threaded bolts, or the like, for example. Further fastening options, alternatively or in addition to the already described clamping of the housing 12, e.g. via mechanical holders or brackets, are conceivable and possible. In this context, it is also conceivable to fasten the signal light 10 to the construction machine/working machine/agricultural machine or to the vehicle via a corresponding mechanical holder, by means of which the signal light 10 can be fastened to the machine/the vehicle simply and without further tools.

[0045] While this invention has been described in terms of several embodiments, there are alterations, permutations, and equivalents which fall within the scope of this invention. It should also be noted that there are many alternative ways of implementing the methods and compositions of the present invention. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations and equivalents as fall within the true spirit and scope of the present invention.
