DETAILED DESCRIPTION OF THE INVENTION

[0042] The lighting system shown in FIG. 1 has a movable frame 2, on which a panel 3 is mounted. This panel 3 has infrared emitters 4, water nozzles 5 and LED emitters 6. These LED emitters 6 are implemented as UV emitters.

[0043] The panel 3 includes two fold-out panel elements 7, 8, which are attached to the movable frame 2 such they can be folded upwards.

[0044] In the folded-out state the panels cover an area of approximately 22 meters by 14 meters. As a result, the lighting system has a span of about 22 meters in one direction and of about 14 meters in the orthogonal direction.

[0045] FIG. 1 shows a schematic view of a reel 11, which is connected to the frame 2 via a tube 12. This reel 11 is designed such that it always keeps the tube that runs between the reel 11 and the frame 2 as taut as possible. This means that only the minimum cable length is always resting on the ground or the grass surface. The reel 11 preferably tensions the tube so that the taut tube does not rest on the turf. In the case of larger distances to be bridged between the reel 11 and the frame 2, the tube 12 can be held at a distance above the grass surface using supports (not shown).

[0046] The tube 12 conducts both water for the water nozzles 5 on the fold-out panel elements 7, 8 and also electricity for the infrared emitters 4 and the LED emitters 6, which are mounted on the fold-out panel elements 7, 8 and the movable frame 2.

[0047] The frame 2 has a draw shaft 13, 14 at each opposite end, which is motor-driven. At the ends of each draw shaft 13, 14 independent wheel suspensions 15, 16 or 17, 18 are positioned, which support rubber tires 19, 20, 21, 22.

[0048] A controller 23 allows the frame 2 to be remotely controlled with a plurality of motors (not shown) and the panel 3 to be moved up and down relative to the ground 24.

[0049] During the use of the lighting system, the frame with the panels is first moved manually and supported by motors onto a grass surface to be treated. The frame 2 is then connected to the reel 11 via the tube 12. On a football field, a plurality of frames, each with one panel, are preferably arranged side-by-side, so that they can be moved slowly over the football field at the same time.

[0050] In the process, atomized water is emitted via the water nozzles 5, which waters the grass surface.

[0051] The infrared emitters 4 heat the nebulized water and the turf 24. At the same time the LED emitters illuminate the ground with specific wavelengths of light, which promote the growth of the grass. With the nebulized water which is heated by the infrared emitters 4, the moisture content of the grass surface can be adjusted while at the same time, the grass surface can be heated.

[0052] A heating device 25 and 26 is suspended on each of the right and left sides of the controller 23 in

[0053] The exemplary embodiment shown in FIGS. 7 and 8. In the cold season, these heating devices are arranged in such a way that infrared radiation 27 radiates onto the ground 24 in the area in front of the wheels 19, 20 in order to heat the grass there and to prevent breakage of frozen grass stems.
