Abstract

In a mobile part having at least one module, and a method for operating a mobile part, the mobile part is able to be moved on a driving surface, and the module includes a controllable illumination device. The illumination device is provided and/or situated in elongated form along a planar curve, in particular, a line.

First claim

The invention claimed is:

1. A mobile part, comprising:
at least one module including a controllable illumination device arranged and/or positioned in elongated form along a planar curve having two concavely curved regions that are set apart from each other and a convexly curved region arranged between the two concavely curved regions, the illumination device including light sources arranged along the concavely curved regions and the convexly curved region.

2. The mobile part according to claim 1 , wherein the mobile part is movable on a driving surface.

3. The mobile part according to claim 1 , wherein the illumination device includes an LED band.

4. The mobile part according to claim 1 , wherein the light sources include LEDs arranged at regular intervals from one another.

5. The mobile part according to claim 1 , wherein the module is arranged on and/or screw-connected to the mobile part, the mobile part being movable on a driving surface, a projection of the mobile part perpendicular to the driving surface having the module at an outer frame and/or in a corner region of the projection.

6. The mobile part according to claim 1 , wherein the module is connected and/or screw-connected to a frame of the mobile part, the module is electrically suppliable from an energy accumulator of the mobile part via a plug connection, and/or a surface of the module includes a convex region arranged between two concave regions and/or depressions that are set apart from each other.

7. The mobile part according to claim 6 , wherein a first region of (a) the illumination device and/or (b) a curve along which the illumination device is arranged is arranged in the convex region, a second region of (a) the illumination device and/or (b) the curve is arranged in one of the concave regions, and a third region of (a) the illumination device and/or (b) the curve is in one of the concave regions.

8. The mobile part according to claim 6 , wherein the concave regions are arranged as depressions on the surface of the module and/or the depression relate to a plane that is aligned in parallel with a driving surface.

9. The mobile part according to claim 1 , wherein the illumination device is provided on the module and/or on a surface of the module, the illumination device is arranged elongated form along a curve, or a planar curve, and/or a line aligned in parallel with and/or set apart from a driving surface and/or a plane that encompasses rotational axes of wheels of the mobile part.

10. The mobile part according to claim 1 , wherein the module is arranged in an outer corner region of a frame of the mobile part and/or the module is arranged as a rounded outer corner region of a projection of the mobile part that includes the module perpendicular to a driving surface.

11. The mobile part according to claim 1 , wherein additional modules having a similar and/or identical configuration as the module are provided on the mobile part, the additional modules being arranged on an outer corner region of a frame of the mobile part and/or arranged as a respective rounded outer corner region of a projection of the mobile part including the module perpendicular to a driving surface.

12. The mobile part according to claim 11 , wherein the additional modules are arranged to provide all-around monitoring and/or radar sensors of the additional modules are adapted to monitor an entire angle at circumference region in relation to a center point situated in the mobile part in a plane extending in parallel with a driving surface.

13. The mobile part according to claim 1 , wherein the module includes at least one radar sensor.

14. The mobile part according to claim 13 , wherein the radar sensor is adapted to monitor a space region and/or determine a distance of objects from the radar sensor.

15. The mobile part according to claim 1 , a housing of the module includes uninterrupted slots aligned in parallel with a driving surface.

16. The mobile part according to claim 15 , wherein a further illumination device is arranged in an interior space region of the module surrounded by a housing and is adapted to generate light that emerges via the slots in a direction of the driving surface.

17. A method for operating a mobile part as recited in claim 1 , comprising:
actuating the illumination device at a clock pulse frequency that is greater than 500 Hertz; and
controlling a hue, a color and/or a flashing frequency of light emitted by the illumination device as a function of a detected distance of an object from the mobile part;
wherein the clock pulse frequency is increased with a decreasing flashing frequency.

18. The method according to claim 17 , wherein the flashing frequency is less than 10 Hertz.

19. The method according to claim 17 , wherein the clock pulse frequency is increased proportionally with the decreasing flashing frequency.

20. The method according to claim 17 , wherein the hue is controlled from red via orange and then via yellow to green with decreasing distance decreases from a first value to a second value, and/or the illumination device has a plurality of LEDs, a number of the LEDs being controlled as a function of the sensed distance of the object.

21. A system, comprising:
a planar driving surface and a mobile part as recited in claim 16 .

22. A mobile part movable on a driving surface, comprising:
at least one module including a controllable illumination device arranged as an LED band, the illumination device arranged and/or positioned in elongated form along a planar curve having two concavely curved regions that are set apart from each other and a convexly curved region arranged between the two concavely curved regions, the illumination device including LEDs arranged along the concavely curved regions and along the convexly curved region at regular intervals from one another, the module being positioned on the mobile part such that a projection of the mobile part perpendicular onto the driving surface has the module at an outer frame and/or on a corner region of the projection, the module being screw-connected to a frame of the mobile part, the module being electrically suppliable from an energy accumulator of the mobile part via a plug connection; and
further modules provided on the mobile part and having a similar and/or identical configuration as the module, the additional module being arranged in an outer corner region of the frame of the mobile part and/or being arranged as a respective rounded outer corner region of the projection of the mobile part including the module perpendicular onto the driving surface;
wherein in each module includes at least one radar sensor adapted for all-around monitoring, a housing of the module includes uninterrupted slots aligned in parallel with the driving surface, and a further illumination device is arranged in an interior space region of the module surrounded by the housing of the module, so that light generated by the further illumination device emerges via the slots in a direction of the driving surface.
