摘要 |
<p>The invention relates to a marking system comprising lighting devices, for example LEDs (11), that are used on a sport area (1) to indicate demarcations (100) of different games. By activating the associated lighting devices (11), the demarcations (100) of a particular game can selectively be made visible. The marking system may further comprise detection devices that can detect the occurrence of certain game events. Thus photodetectors (12) may for example detect if a ball (2) crosses a demarcation (100). A controller (13) may then activate the lighting devices (11) or separate signaling devices (14, 15) to indicate the detected event. The controller (13) may further communicate wirelessly with persons on the sport area, particularly with the referee to assist his/her decisions.</p> |
