<p>PURPOSE:To lighten the burden of a specialist at times of spot assigning operation and lamp control operation and simultaneously perform safety lighting control suited to weather as well as to prevent any useless lighting of parking illumination attributable to some oversight oblivious of light-off. CONSTITUTION:Spot assignment of each aircraft is operated from input information by an operational part 4, while illuminance in and around the spot periphery is measured by a daylight sensor 6 set up in the spot periphery. Each lighting schedule of both spot parking and safety lightings is programmed by a control part 5 from the measured result of the daylight sensor 6 and the operated result of the operational part 4, and then ON/OFF operation of these parking and safety illuminations installed in each spot on the basis of a lighting schedule is performed by an output part 7.</p> |
