Description

The invention relates to a lighting device, in particular shop lighting, comprising a support device extending in a plane and / or curved surface and a plurality of lighting units.

It is known to light units on different surfaces, e.g. fixed to a wall or ceiling. The lighting units can then no longer be changed in their position. A reaction to a changing lighting situation is not possible.

It is therefore an object of the invention to provide an illuminating device and a method for illuminating a room which enables a reaction to a changing illuminating situation.

This object is achieved by the subject matter and the method of the independent claims.

The lighting device can be used, for example, in shopfitting. In particular, the lighting device can be designed as shop and / or shelf lighting.

For example, the lighting device in retail, e.g. Supermarket, discounter, drugstore, pharmacy, bakery, butcher, cheese shop, fruit shop, vegetable shop, flower shop, market stall, perfumery, jewelry store and / or fashion store can be used. Furthermore, the lighting device can e.g. can be used in a parking garage.

The lighting device can be used outdoors and / or indoors, e.g. in offices, shops, restaurants, hotels or houses. In particular, the lighting device can serve as main lighting, as object lighting, as decorative lighting, as orientation lighting and / or as signal lighting.

According to the invention, the lighting device comprises a support device extending in a plane and / or curved surface.

In the following, the term plane always implies a curved surface.

In particular, the support device spans a plane. In contrast to, for example, a purely linear rail, the carrying device thus preferably extends in a further direction.

The lighting device comprises at least one drive device and a plurality of lighting units which can be moved individually by means of the drive device (s).

In particular, the drive device can have an electric motor.

The drive device or at least part of it can e.g. be integrated into the lighting unit. However, an external drive device is also conceivable, for example in the carrying device.

The external drive device and the lighting unit can, for example, be arranged on different sides of the carrying device. In particular, the drive device and the lighting unit can be magnetically connected to one another. If the drive device is consequently moved, the lighting unit also moves due to the magnetic connection. The lighting unit can thus to a certain extent be split into two parts, namely a drive part with the drive device and an illumination part with a light source.

For example, a separate external drive device can be assigned to each lighting unit. Alternatively, an external drive device can also drive several lighting units.

The lighting unit includes in particular one or more light sources, e.g. LEDs. For example, at least one red, green, blue, cyan, magenta, yellow or white LED can be provided.

In particular, each lighting unit can have at least one energy store. The energy store can be designed, for example, as an, in particular integral, accumulator.

The term energy storage is to be understood broadly and includes, for example, energy absorbers for absorbing energy through e.g. Induction.

A wireless power supply is possible in particular through the energy store.

The lighting device may preferably be a loading zone, e.g. Charging station for which have energy storage. For example, the lighting unit can move into the charging zone if necessary to recharge the energy store there.

The energy store can serve in particular to supply power to the light source (s) and / or the drive device.

Each lighting unit has at least one holding device for holding on the carrying device. The holding device can in particular form part of the drive device. For example, the lighting unit can have one wheel or several wheels, for example two, three, four, five, six or more. The light unit can be driven, for example, by means of the wheels. In particular, a separate drive device, for example an electric motor, can be assigned to each wheel.

In addition, the lighting unit can hold the carrier device, for example, by means of the wheels. So the wheels can e.g. engage in a support device designed as a rail system or engage behind it. For example, the rails can be designed as U-profiles. The wheels can e.g. be magnetic.

The lighting unit can in particular be designed as a movable and / or positionable trolley, for example as a so-called light messenger.

Each lighting unit can be moved in at least two directions of a movement surface, in particular a movement plane, which are not oriented parallel to one another. The lighting units can preferably be moved independently of one another. The movement takes place in particular by means of the drive device.

The movement surface is in particular oriented parallel to the plane of the carrying device. The lighting units can thus preferably be moved in a plane parallel to the carrying device.

The lighting unit can preferably be moved as desired or along a grid in the plane.

In addition to a movement in directions oriented parallel to one another, a movement surface, e.g. a movement back and forth, movement in at least one other direction in this plane is also possible.

Movement outside the plane is also possible in particular. For example, the light source can be arranged variably in two-dimensional or, if appropriate, even in three-dimensional space.

According to the invention, the lighting units can be moved extremely variably. In this way, the lighting device can react to a changing lighting situation.

If, for example, the display in a shop, e.g. a shop window, changed, the lighting units can be moved, for example, to optimally illuminate the new display, e.g. as bright and / or effective as possible.

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

According to one embodiment, each lighting unit can be moved as desired in the movement area, in particular a movement plane. The lighting units can preferably move as desired independently of one another. The freedom of movement is not restricted, for example, by a grid or the like. The lighting units can thus be moved in any direction in the movement area.

Even if the freedom of movement of the lighting units is fundamentally not restricted, the movement of the lighting units can nevertheless be coordinated and / or coordinated with one another. For example, a collision of the lighting units can be prevented. The lighting units can also move, for example, like a swarm. If, for example, a certain corner area is to be illuminated, several lighting units can be moved there.

According to a further embodiment, each lighting unit has an omnidirectional drive device. The lighting unit can e.g. have one or more Omni and / or Mecanum wheels. These can be magnetic, for example.

Thanks to the omnidirectional drive device, the lighting units can be easily moved in any direction in the movement area.

According to a further embodiment, the carrying device comprises a continuous and / or plate-shaped holding surface. The holding surface can in particular be smooth. For example, the holding surface can be formed by a normal wall and / or ceiling. In particular, however, a coating can also be provided.

The holding device can comprise, for example, a vacuum device. The lighting unit can e.g. hold onto the holding surface by means of a vacuum.

For example, the holding surface can be structured. The holding surface can in particular comprise or consist of a metamaterial. In particular, the lighting unit, for example with feet or claws, intervene in the structure of the metamaterial.

Movement of the lighting unit on vertical walls and / or overhead, e.g. on ceilings is made possible.

According to a further embodiment, the holding surface is magnetic and / or comprises a metal material, e.g. Iron. Correspondingly, the lighting unit can also comprise a metal material and / or at least one magnet as a holding device. For example, one or more, preferably all, of the wheels of the lighting unit can be magnetic. Alternatively or additionally, another, in particular additional, component can also be designed magnetically.

If, for example, the lighting unit is divided into two and has an external drive unit, the carrying device can in particular also be a non-magnetic and / or non-metallic material, e.g. a plastic and / or glass material, or consist of. The magnetic field between the external drive unit and the lighting unit is consequently not influenced by the carrying device.

The magnet of the holding surface and / or the lighting unit can in particular be a permanent magnet or electromagnet.

Movement of the lighting unit on vertical walls and / or overhead, e.g. on ceilings, can also be made possible by the magnets.

According to a further embodiment, the carrying device comprises a rail system, in particular arranged in a grid. In particular, the lighting units, e.g. on a ceiling, in the X and Y direction or, e.g. on a wall, movable in the Y and Z directions.

With sloping and / or curved rails, other directions of movement are also possible accordingly.

For a lane change, the wheels of the lighting units in particular can be retracted and / or extended, for example in pairs. For example, two pairs of wheels must be oriented at right angles to each other. One pair can be extended to change lanes to the new lane, while the other pair can be retracted from the previous lane.

The rail system can in particular comprise conductor rails. The drive device and / or the light sources can thereby be supplied with current.

The lighting units can for example be arranged below a rail and in particular hang on this. The rails are therefore not in the way of the emerging light.

The lighting unit can have one or more rollers and / or sliding blocks as a holding device. The holding device can in particular engage in or engage behind the rail.

According to a further embodiment, the carrying device is oriented vertically and / or horizontally. In particular, the carrying device is arranged or can be arranged in an area above the floor, preferably a ceiling area.

The lighting unit preferably stops on a vertical wall and / or overhead on a ceiling. The lighting unit can also be arranged on an upper side of the carrying device.

According to a further embodiment, the holding device comprises an adjusting device for adjusting a part of the lighting unit, in particular a light source, perpendicular or obliquely to the plane of the carrying device.

The lighting unit can in particular also be adjusted perpendicularly or obliquely to the actual movement area.

For example, the lighting unit can be viewed from above, e.g. from the ceiling. For this, e.g. a wire, in particular made of steel, a rope, a cord and / or a telescopic rod can be used. The lighting unit can be lowered like a spider.

If the movement surface is oriented parallel to the floor or a wall, the lighting unit can be raised, for example, from below or extended to the side. For this, e.g. a telescopic rod can be used.

In this way, the lighting unit can be adjusted in three dimensions, in particular as desired.

According to a further embodiment, the direction of radiation of the lighting unit is oriented perpendicularly or obliquely to the movement surface, in particular to a movement plane.

If the light units are moved parallel to the ceiling, for example, they can emit light downwards. For illuminating high rooms, e.g. for architectural lighting, lighting upwards is also possible. In this way, accents in particular can be set in the room and / or architectural elements can be illuminated and / or emphasized.

If, on the other hand, the lighting units are moved parallel to a wall, for example, the light can emit to the side.

According to a further embodiment, a manual control device is provided for manually controlling the lighting units.

With an input device, e.g. Computer, tablet PC or smartphone, the desired position of the lighting units can be entered. The lighting units can then move accordingly into the desired position.

According to a further embodiment, an autonomous control device for autonomously controlling the lighting units is provided. This autonomous control device can be provided as an alternative or in addition to the manual control device.

The autonomous control device can in particular have an artificial intelligence.

For example, the lighting device can have a sensor device with one or more sensors. In this way e.g. the degree of illumination can be determined. If there is too much or too little light, the control device can react accordingly. The lighting units can then be moved accordingly.

The sensor device can in particular be an optical system, e.g. have a camera, preferably an image camera and / or a time-of-flight (TOF) camera. In particular, a distance measurement can be carried out using a runtime method.

For example, a removed and / or modified goods can be recognized in a shop, in particular a shelf. The lighting device can react to this and e.g. adjust the lighting conditions.

It is also possible to determine a position within rooms (indoor navigation). Moving shelves can result in a change in position of the sensors. The new shelf position can be recognized. The lighting units can then be adjusted to the new conditions in terms of lighting technology and position. This also applies to the alignment with other objects, e.g. Mannequins, excellent goods or the like.

To record new situations in the aisle or on the shelves, customer movement data can also be recorded, e.g. in the context of so-called heat maps. Zones that customers e.g. little frequented can be recognized. By changing the lighting, e.g. by adding lighting units and / or changing the brightness, a change in customer behavior can be brought about in these areas, or at least acted on.

Furthermore, e.g. Certain goods, e.g. offers, located by indoor navigation and customer attention e.g. can be increased by increasing the brightness.

For example, the sensor device may e.g. capture the position of a person. This can be done using a shopping cart, e.g. using RFID, BLE beacons, WLAN or the like. The lighting units can then follow the person, for example, or lead ahead for navigation and illuminate the path accordingly. Also e.g. a vehicle can be navigated in a parking garage, for example to the next free parking space.

According to a further embodiment, the control signals can be passed on from one lighting unit to another lighting unit.

In particular, e.g. a mesh-like forwarding of data and / or control signals possible.

Wireless transmission technologies such as UMTS, GSM, LTE, 5G, Bluetooth, infrared, WLAN, BT, ZigBee, NFC, Wibree, WiMAX, IrDA, optical directional radio, e.g. by means of Li-Fi (light fidelity) or VLC (Visible Light Communication), or the like can be used for data transmission.

In particular, a lighting unit can receive a signal and then pass it on to other lighting units. Each lighting unit preferably comprises a transmitting and / or receiving device.

According to a further embodiment, the control device is designed to adapt the movement, position and / or the light property, in particular the color and / or intensity, to the lighting unit.

In particular, the light that is emitted by the lighting unit is adaptable.

The light property can e.g. the color, a color change, the brightness and / or the radiation angle. In particular, the color, a color change, dimming and / or a focus, e.g. different beam angles can be adjusted.

In particular, therefore, both a mechanical adjustment, for example the position, and a lighting adjustment of the lighting units can take place.

According to a further embodiment, the control device has a storage device for storing a setting, in particular the movement, position and / or the light property, of the lighting units.

For example, the setting for a specific lighting situation can be saved and called up as required. For example, Christmas lights can be stored, which are called up at Christmas time. The lighting units can then be moved to the corresponding positions.

If a lighting device is optimized for a specific lighting situation, the control signals can be transmitted to a further lighting device in which there is a similar lighting situation. In this way, several lighting devices, in particular also at different locations, e.g. different stores, operated with a unique optimization.

For example, the same setting can be called up in a chain of department stores in all stores. For example, in stores the same Christmas lights can be set.

The invention also relates to a method for illuminating a room, preferably a shop, in particular by means of an illumination device according to the invention.

A situation is detected by means of a sensor. For example, the brightness and / or the distribution of objects in the room can be determined.

Depending on the situation, a plurality of individually movable lighting units, each with at least one holding device for holding on a support device extending in one plane and in particular with at least one energy store, are moved in a movement area by means of at least one drive device.

The situation that is recorded can e.g. to be a lighting situation. For example, determine whether e.g. a section is too light or too dark.

The situation can also be recorded when a shelf is moved and / or rearranged.

Furthermore, e.g. the situation is recorded that a person is approaching. This person can e.g. the way to be displayed.

The lighting units can preferably move in at least two directions which are not oriented parallel to one another, for example along a rail system arranged in a grid. With a corresponding configuration of the carrying device, free movement in a movement area is also possible.

In particular, at least a part of the lighting unit, e.g. a light source can be adjusted perpendicularly or obliquely to the level of the carrying device. This allows the light source to be moved to almost any position in three-dimensional space.

The movement, the position and / or the light property, in particular the color and / or intensity, can preferably be adapted to the lighting unit.

All of the embodiments and components of the device described here are designed in particular, e.g. by means of a control device to be operated according to the method described here. Furthermore, all the embodiments of the device described here and all the embodiments of the method described here can be combined with one another, in particular also detached from the specific embodiment in the context of which they are mentioned.
