LIGHTING DEVICE

The invention relates to a lighting device, in particular a lighting device with a lamp housing and a lamp.

As part of the design of a room, for. B. in a shop or in a museum, the design of lights is usually matched to the rest of the design of the room. When redecorating, however, it can happen that the design of the lights no longer matches the rest of the room. So far, it has been necessary to replace the lights when redecorating a room or at least to replace individual housing elements of the lights. On the one hand, this requires a large amount of resources and, on the other hand, it requires complex renovation measures.

In particular, since modern lighting technologies have enabled a significant increase in the life of the lights, there is a need for a simple and inexpensive way to adjust the external appearance of lights.

[0004] Document WO 2014/037359 A1 shows a luminaire which has environmental sensors. These sensors determine color information of the environment. The light emitted by the lamp is automatically adapted to the color of the surroundings. The disadvantage here, however, is that the exterior design of the lamp is not adaptable.

The invention is therefore based on the object to provide a lighting device which can be changed in terms of its external appearance without causing great effort in changing the external appearance.

The object is achieved for the device by the features of independent claim 1. Advantageous further developments are the subject of the dependent claims referring back to this.

A lighting device according to the invention has a lamp, a lamp housing and a control device. The lamp is designed to illuminate an environment of the lighting device. The luminaire housing has at least one surface element which has a lighting device. The lighting device is designed to selectively emit light, controlled by the control device, over defined parts or areas of at least one surface of the surface element. In other words, light can be emitted in a targeted and defined manner (for example also selectively adapted in the light spectrum) over different areas (for example large or small, defined or undefined areas or also one or more pixels) of the surface of the surface element. Conversely, this means that no light can be emitted in defined areas. This ensures that a variable appearance of the lighting device is achieved by different lighting or radiation from the surface of the surface element. For example, patterns and structures can also be displayed on the surface. This creates an almost unlimited variability in the external appearance of the lighting device.

Preferably, the lighting device is designed to be controlled by the control device to display colored or black and white symbols, patterns, messages, images, animations, or videos on the at least one surface of the surface element. This provides maximum flexibility in the design of the lighting device. In addition, an information display on the surface is possible.

[0009] The lighting device preferably has a light generating device and a light control device. The light generating device can be designed to generate light over a large area. The light control device is designed to control the light generated by the light generating device and the light thus controlled via the

to emit or emit correspondingly defined areas of the at least one surface of the surface element. In this way, particularly precise control of the light emission and thus the design of the external appearance of the lighting device can be achieved.

The light generating device is preferably a fluorescent lamp or an LED module or an OLED module or a projector. Alternatively, the light generating device can be identical to the lamp. I.e. The light control device is also illuminated (i.e. backlit) by the lamp which is used to illuminate the surroundings of the lighting device. In this case, the light emitted by the lamp is regulated by the light control device. Additionally or alternatively, the light control device can be an LCD matrix or a selectively controllable color filter or an Eink matrix or a micromirror array. A very flexible construction of the lighting device is achieved.

[0011] The lighting device preferably has at least one sensor. The control device is then designed to control the lighting device for emitting light over the defined areas of the at least one surface of the surface element as a function of measured values from the sensor. It is thus possible to react flexibly to environmental conditions and to present application scenarios that are useful for users. Control on the basis of sensed sensor signals can be carried out centrally or decentrally directly on the lighting device via a central control system.

[0012] The lighting device preferably has a color sensor. The control device is then designed to control the lighting device for emitting light, which is matched to an ambient color determined by the color sensor, via the defined regions of the at least one surface of the surface element. This ensures that no manual intervention is necessary when redecorating. Rather, the external design of the lighting device can automatically adapt to the color scheme prevailing in the environment.

[0013] Additionally or alternatively, the lighting device comprises a presence sensor for determining the presence of a person in the immediate vicinity. The control device is then designed to control the lighting device for displaying specific information based on the presence or absence of a person in the environment on the at least one surface of the surface element. The light can also be specifically deactivated or dimmed when a person is absent.

[0014] Additionally or alternatively, the lighting device has a temperature sensor. The control device is then designed to control the lighting device for the temperature-dependent display of certain information and / or colors on the at least one surface of the surface element. In addition, temperature-dependent control of the light temperature of the lamp and / or the lamp housing is possible.

Additionally or alternatively, the lighting device has a fingerprint sensor. The control device is then designed to control the lighting device for displaying personal information on the at least one surface of the surface element if the authentication by means of the fingerprint sensor is successful.

[0016] Additionally or alternatively, the lighting device has a distance sensor which is designed to determine an installation height of the lighting device. In this case, the control device is designed to display a display size and / or a display content of the lighting device on the at least one surface of the surface element as a function of the mounting height. Additionally or alternatively, it is designed to set an illuminance of the luminaire and / or to set an addressing of the lighting device and / or to activate an emergency lighting function and / or to determine an area of application of the lighting device and

to set an afterglow time after switching off and / or to determine an expected aging characteristic of the lamp and the lighting device and to control the lamp and the lighting device to compensate for the aging characteristic. A variety of useful application scenarios can be represented using the sensors.

[0017] The lighting device preferably has at least one communication interface, preferably a Bluetooth interface or a WLAN interface or a DALI interface or a powerline interface. The control device is then aligned in order to control the lighting device for emitting light via the correspondingly defined areas of the at least one surface of the surface element as a function of control commands entered via the communication interface. The communication interface is preferably designed to receive control commands from a mobile phone app or a control computer and to execute them accordingly. The lighting device can thus be operated in a very simple manner. The light output can also be adjusted, for example, using a touch panel and the like provided on the lighting device.

[0018] The surface element preferably has a housing and / or a mounting element and / or a cable. The lighting device is designed to selectively emit light controlled by the control device over defined parts or areas of the at least one surface of the housing and / or the mounting element and / or the cable. All other housing or housing elements of a lighting device are also conceivable here for the light emission according to the invention over the correspondingly defined areas; For example, also accessories such as canopies, holders, suspensions, device boxes and the like, as well as internal components such as the back of reflectors or diffuser plates. The entire outer surface of the lighting device can thus be adapted in terms of its external appearance.

[0019] The control device is preferably designed to control the lighting device in the event of an emergency for displaying emergency instructions and / or escape route instructions on the at least one surface of the surface element.

Additionally or alternatively, the control device is designed to control the lighting device for displaying an operating state of the lamp on the at least one surface of the surface element.

Additionally or alternatively, the control device is designed to control the lighting device to display an indication of necessary maintenance / repair work on the lighting device on the at least one surface of the surface element.

[0022] Additionally or alternatively, the control device is designed to control the lighting device for displaying messages on the at least one surface of the surface element.

[0023] Additionally or alternatively, the control device is designed to control the lighting device for displaying an indication of a need for cleaning of the lighting device or an environment of the lighting device on the at least one surface of the surface element.

Additionally or alternatively, the control device is designed to control the lighting device to display an indication of a request for undisturbed work by a person in the area of the lamp on the at least one surface of the surface element.

A large number of useful application scenarios of the lighting device can thus be represented.

The invention will be described by way of example with reference to the drawing, in which an advantageous exemplary embodiment of the invention is shown. The drawing shows:

[0027] FIG. 1 shows a first exemplary embodiment of the lighting device according to the invention;

[0028] FIG. 2 shows a detail of a second exemplary embodiment of the lighting device according to the invention;

Fig. 3 shows a third embodiment of the lighting device according to the invention in a block diagram;

4 shows a detail of a fourth exemplary embodiment of the lighting device according to the invention in a block diagram;

[0031] FIG. 5 shows a fifth exemplary embodiment of the lighting device according to the invention;

Fig. 6 shows a sixth embodiment of the lighting device according to the invention;

7 shows a seventh exemplary embodiment of the lighting device according to the invention, and

8 shows an eighth exemplary embodiment of the lighting device according to the invention.

First of all, the general structure and the general functioning of the exemplary embodiments of the lighting device according to the invention are illustrated with reference to FIG. 1. 2-4, the detailed structure of various exemplary embodiments of the lighting device according to the invention is discussed in more detail. Finally, with reference to FIG. 5, FIG. 8, various application scenarios of the exemplary embodiments of the lighting device according to the invention are discussed. Identical elements were sometimes not repeatedly shown and described in similar illustrations.

1 shows a first exemplary embodiment of the lighting device 1 according to the invention. The lighting device 1 contains a lamp 2, in this example a fluorescent lamp. Instead of a fluorescent lamp, a lamp with an LED module or a lamp with other lamps can also be used. In addition, the lighting device 1 includes a luminaire housing 3, which here has a mounting element 4 and cables 5, 6 connected to it and, in turn, a housing 11 connected to the cables 5, 6. The housing 11 has a plurality of surfaces 8, 9 and 10. In addition to the outer surfaces 8, 9 and 10 shown here, the housing 11 naturally also has a rear surface and an inner surface. However, these are not shown and numbered separately here. Furthermore, the invention is not restricted to the number, shape and size of surfaces.

The lamp 1 is mounted for example in a room on the ceiling. For this purpose, it is attached to the ceiling with the mounting element 4. In order not to have to make any changes to the lighting device 1 when the room is newly decorated, the lighting device 1 is designed so that its outer appearance can be adapted to the new design of the room with little effort. For this purpose, the housing 11 forms a so-called surface element 7, for example, with a plurality of surfaces 8, 9 and 10, which can be adapted or individually designed to the appearance of the room by selective light emission via defined areas of the surfaces 8, 9 and 10. Colors or patterns can be displayed flat on the surfaces 8, 9 and 10. Alternatively, symbols or messages or images or animations or videos can also be displayed on the surfaces 8, 9 and 10. This is done by selective light emission over defined areas of the surfaces 8, 9 and 10 with the aid of an illumination device which is functionally integrated in the surface element 7. This can be, for example, an LED module or an OLED module or a projector, etc. The OLED module can be transparent. The exact function and display option is shown in Fig. 5-8.

In Fig. 2 is a detailed view of a second embodiment of the invention

essen lighting device 20 shown. Only different layers 20, 21, 22 of the surface element 7 are illustrated here. Layer 20 represents a housing level 20. The housing level 20 serves, for example, for the structural strength of the surface element 7. The housing level can have a fastening surface or a fastening frame to which the further layers 21, 22 can be fastened or integrated. Additional components can be offered as an additional part or retrofit kit.

Applied to the housing level 20 is a light and color level 21, which is used for the generation of optionally colored light for selective light emission over defined areas of the surface 9. The light and color plane 21 does not have to be flat, but can take any shape. Simply curved or curved shapes are just as conceivable as step-like or pyramid-shaped designs. A division of the light and color plane 21 into different areas, which are served by different sources, is conceivable.

The light and color plane 21 is, for example, an LED module or an OLED module or a projector or an electro-luminescent module. Light guides can also be used. Alternatively, instead of active lighting, only the light from the luminaire 2 from FIG. 1 can be passed on here. In this case, the housing level 20 is to be made transparent.

The layer 22 represents a contrast plane 22. Its task is the modulation of the light generated by the light and color plane 21. It can be designed as a pixel or matrix-like controllable contrast plane, whereby the luminaire housing becomes a display in the broadest sense.

In the simplest case, the contrast plane 22 is a partially translucent and partially non-translucent film or layer. For example, Wood grain or other patterns can be shown on the surface of the surface element 7. Alternatively, the contrast plane 22 is an active component, for example an LCD matrix or a selectively controllable color filter or an e-ink matrix or a micromirror array. In these cases, the contrast plane 22 is used for active modulation of the light provided by the light and color plane 21. The modulation can go so far that videos and animations can be displayed. With a simpler construction, at least colored areas or sample areas or images can be represented.

The layers 20, 21 and 22 can be arranged in a different order from the illustration. An integration of several layers 20, 21 and 22 in common components is also conceivable. Depending on the technology selected, e.g. the light / color plane 21 and the contrast plane 22 coincide. This is the case, for example, with an OLED module.

FIG. 3 shows a further exemplary embodiment of the lighting device 1 according to the invention in a block diagram. The lighting device 1 includes a control device 30, a lighting device 31, a sensor device 32, a communication interface 33 and a lamp 2, as already shown in FIG. 2. The lighting device 31, the sensor device 32, the communication interface 33 and the lamp 2 are connected to the control device 30 and are controlled by the latter.

The lighting device 31 serves to illuminate the surfaces 8, 9 and 10 of the surface element 7, that is to say to selectively emit light over defined regions of the at least one surface of the surface element, as shown in FIG. 1. It contains the light and color plane 21 and the contrast plane 22 from FIG. 2.

The sensor device 32 contains one or more sensors which scan the surroundings of the lighting device 1. The compilation of the sensors and their respective function is discussed in more detail with reference to FIG. 4.

The communication interface 33 is used for communication with operating devices. -

for example, the communication interface is a Bluetooth interface or a WLAN interface or a DALI interface or a Powerline interface. The communication interface 33 can be used with one of the control computers cited or with mobile telephones or tablets, or smart glasses such as Google Glass or smart watches, etc. can be communicated. Control of the lighting device 1 is thus possible with the aid of the communication interface 33. As already explained, the lamp 2 serves to illuminate the surroundings of the lighting device 1. It is also controlled or controllable by the control device 30. In particular, the various devices that can be used for control purposes can supplement or replace the functions of sensor device 32 via built-in sensors. E.g. For example, a camera installed in a cell phone can recognize the color of the surroundings and control the lighting device 1 via the communication interface 33 in order to adapt the lighting of the surface element 7 to it. In this case, the cell phone takes on the function of a color sensor.

The function can be done using e.g. a switch or a touch display on the lighting device 1 or in the vicinity of the lighting device 1. It is also possible to adjust the contrast and color.

With the aid of the lighting device 31, the control device 30 is designed to e.g. in the event of an emergency, to present emergency instructions and / or escape route instructions on the at least one surface 8, 9, 10 of the surface element 7. For example, Danger areas are indicated by the surface element 7 lighting up red and escape routes are indicated by the surface element 7 lighting up green.

In addition or as an alternative, operating states of the lamp 2 can be represented on the surface 8, 9, 10 of the surface element 7. For example, it can be shown in which dimming state the lamp 2 is. In addition, indications of necessary maintenance and repair work on the lighting device or in the vicinity of the lighting device can be displayed on the surface 8, 9 and 10 of the surface element 7. This significantly simplifies the finding of a repair location for an employee responsible for the repair.

A representation of information and messages on the at least one surface 8, 9 and 10 of the surface element 7 is also conceivable. For example, an employee who is not currently at his workplace can be informed by a message on the lighting device 1 above his workplace that important tasks are waiting for him at his workplace. In order to achieve the most detailed representation possible, high-resolution technology, such as LCD or OLED can be used.

In addition, a representation of an indication of a need for cleaning of the lighting device or an environment of the lighting device on the surface 8, 9, 10 of the surface element 7 is also possible. This makes it easy for a cleaner to find the location of a work assignment.

Furthermore, a representation of an indication of a request for undisturbed work by a person in the area of the lamp on the surface 8, 9, 10 of the surface element 7 is also conceivable. This can e.g. can be achieved by red lighting of a front part of the lighting device 1.

In this way, colleagues can recognize whether the employee may be disturbed even before he reaches the workplace.

[0055] A large number of application scenarios can thus be implemented. Further application scenarios are discussed in more detail with reference to FIGS. 4-8.

4 shows a fourth exemplary embodiment of the lighting device 1 according to the invention. A detailed view of the sensor device 32 from FIG. 3 is shown here. The sensor device 32 here includes a color sensor 40, a presence sensor 41, a temperature sensor 42, a fingerprint sensor 43 and a distance sensor 44.

All of the sensors can be read independently of the control device 30 from FIG. 3. The combination of sensors shown here is not to be understood as an exhaustive list. Other sensors going beyond this are also conceivable. A reduction to one or more of the sensors shown is also conceivable. In particular, the information from the sensors 40, 41, 42, 43, 44 can be processed by a central control system and control commands for the lighting device 1 can be generated based on this. Alternatively, the sensor information can act directly on the lamp.

The color sensor 40 is used to detect the predominant color in the vicinity of the lighting device 1. Based on the information from the color sensor 40, the control device 30 can then control the lighting device 31 in order to implement the light output over correspondingly defined areas of the surfaces 8, 9 and 10 of the surface element 7 in accordance with the coloring of the surroundings.

The presence sensor 41 is used to determine whether a person is in the vicinity of the lighting device 1. Based on this information, the luminaire 2 or the light output can be set via the surfaces 8, 9, 10 of the surface element 7. For example, it can be shown on the surfaces 8, 9, 10 whether an employee is at his workplace. In this way it can be recognized from a distance whether a wanted employee is available. In addition, the aforementioned notification of an employee who is not at his workplace is also possible based on the data from the presence sensor. No messages of this type are displayed as long as the employee is at his workplace. Messages are only displayed on the lighting device 1 when he is not at his work place.

The temperature sensor 42 is used to detect the temperature of the surroundings of the lighting device 1. Based on the detected temperature, the light temperature of the lamp 2, but also the color of the surface 8, 9, 10 of the surface element 7 can be set. It has been found that the coloring of surfaces and the setting of the light temperature can produce a subjective temperature impression. For example, the luminaire housing 3 can shine in cool colors at a high room temperature or in warm colors at a low room temperature, which can lead to an increase in the efficiency of the people. A corresponding setting is also conceivable regardless of the room temperature.

The fingerprint sensor 43 is used to capture fingerprints for authentication. If authentication is successful using the fingerprint sensor 43, the control device 30 can display personal information on the lighting device 31. In this way, log-in or registration can be carried out using a PC or smartphone, etc. The fingerprint sensor 43 can also be used to check whether there is authorization to change the setting of the lighting device.

In addition, the distance sensor 44 is used to determine the distance of the lighting device from a closest surface, e.g. a table surface or a floor. Areas of application of the lighting device 1 can be determined on the basis of the information from the distance sensor 44. A distinction can thus be made between an office assignment and a corridor application. Depending on this, afterglow times can be set after switching off or color temperatures or illuminance levels, etc.

[0062] The display size and the display content of shapes shown on the surfaces 8, 9, 10 can also be set based on the determined distance from the closest surface. For example, at a high height, information is only displayed in the form of large-scale, luminous color information. With a medium height, coarse and / or large symbols or fonts can be used. Detailed symbols and texts can only be used at low heights.

An illuminance of the lamp can also be set based on the determined distance. In addition, automatic addressing of the lighting device 1 based on the distance is conceivable. This means that luminaires at different heights can be automatically grouped with regard to their addressing. A swarm membership can be controlled by the mounting height, similar to the address area membership.

Depending on the determined distance, emergency lighting functions can also be activated or deactivated. For example, only very high-mounted lights could be used for emergency lighting, since low-mounted lights will probably only illuminate small areas.

An expected aging characteristic of the lamp 2 and the lighting device can also be determined on the basis of the determined height. Experience shows that luminaires placed higher age faster because they are exposed to a higher temperature. To compensate for this aging characteristic, luminaires located higher could be controlled less brightly. The same also applies to the lighting device 31 with which the surfaces 8, 9, 10 are illuminated or via which the light emission is carried out.

5 shows a fifth exemplary embodiment of the lighting device 1 according to the invention. Here, a message is shown on surface 8, while a geometric pattern is shown on surface 9.

6 shows a sixth exemplary embodiment of the lighting device 1 according to the invention. Here, full-area illumination with a uniform color is shown on surface 8. The same also applies to the surface 9. In addition to emitting light via the surfaces 8, 9, 10 of the housing 11 of the surface element 7, it is also possible to emit light via the cables 5, 6 and / or the mounting element 4 and / or other housing elements. In this case, the surface element includes not only the surfaces 8, 9, 10, but also the cables 5, 6 and the mounting element 4. Other components of the lighting device 1 can also be part of the surface element 7. A canopy, a holder, a suspension, a device box or internal components such as a reflector back or diffuser plates can also be part of the surface element 7.

7 shows a seventh exemplary embodiment of the lighting device 1 according to the invention. Here a low mounting height is shown above a surface that is closest. This leads to a very small letter on the surface 9 of the surface element 7, since it is assumed that there is a small distance from the viewer.

8, on the other hand, shows an exemplary embodiment of the lighting device 1 according to the invention, in which there is a large distance from an adjacent surface. This leads to a very capitalized message on the surface 9, since a large viewing distance is assumed.

The invention is not limited to the illustrated embodiment. In particular, it is not limited to a pendant lamp. Spotlights, surface-mounted lights, built-in lights, pendant lights or table lights, etc. can also be used within the scope of the invention. The invention is also not limited to specific lights such as fluorescent lights or lights with LED modules or OLED modules. Any lights with any illuminants can be used. Any display technologies can also be used to design the surfaces. The order of the layer structure is also not limited by the present invention and a plurality of layers can be integrated with one another. E.g. light and contrast levels can simultaneously represent the housing level. All of the features described above or features shown in the figures can be advantageously combined with one another in the context of the invention.
