Title (EN) CONTROLLING A DIRECTED LIGHT SOURCE
(FR) COMMANDE D'UNE SOURCE DE LUMIÈRE DIRIGÉE
(DE) STEUERUNG EINER GERICHTETEN LICHTQUELLE
Abstract:
(EN) A directed light source provides a light cone which is guided over a predetermined region. A method for controlling the light source comprises the steps of determining a movement of the light source; estimating, on account of the determined movement, an upcoming change of a portion of the region illuminated by means of the light cone; determining that the portion is expected to be exposed longer than predetermined by the modified light cone; and providing a darkening signal for the light source.
(FR) L'invention concerne une commande d'une source de lumière dirigée qui fournit un cône de lumière qui est guidé au-dessus d'une zone prédéfinie. L'invention concerne un procédé servant à commander la source de lumière comprenant les étapes consistant à définir un déplacement de la source de lumière, à évaluer une modification imminente d'une section éclairée au moyen du cône de lumière de la zone sur la base du déplacement défini, à définir que la section est exposée à la lumière probablement plus longtemps que spécifié à travers le cône de lumière modifié, et à fournir un signal d'assombrissement pour la source de lumière.
(DE) Eine gerichtete Lichtquelle stellt einen Lichtkegel bereit, der über einen vorbestimmten Bereich geführt wird. Ein Verfahren zum Steuern der Lichtquelle umfasst Schritte des Bestimmens einer Bewegung der Lichtquelle; des Schätzens einer bevorstehenden Änderung eines mittels des Lichtkegels beleuchteten Abschnitts des Bereichs aufgrund der bestimmten Bewegung; des Bestimmens, dass der Abschnitt durch den geänderten Lichtkegel voraussichtlich länger als vorbestimmt belichtet wird; und des Bereitstellens eines Verdunkelungssignals für die Lichtquelle.
