  • the objects of the invention can be achieved by a light assembly as described in the preamble to claim 1 if modified so that the shutter means form a merged pile, where the shutter means in the merged pile are placed with the front area placed over the front area of a first neighbouring shutter means and the front area placed below the front area of the second neighbouring shutter means which shutter means can be individual adjustable.
  • Herby can be achieved a high degree of freedom of moving shutters in different directions to form a framing of a light beam.
  • Forming the shutter means in a merged pile leads to a very thin assembly, where the operating edges of the shutters are operating mostly in the same plane.

  • one active motor in combination with one inactive motor provides the light assembly with the ability to frame a beam of light only partly from one direction or to frame partly from 2-4 directions. Framing is possible for all parallel or no parallel four sided shapes of the framing and for most triangular forms.
  • the present invention provides a high degree of freedom to move shutter means in different directions to form a light beam framing of different forms.
  • At least one of the two toothed sides of the shutters may have a curved or straight toothed outer side. Herby can be achieved further freedom of operation of the shutters.
  • the shutter means can be placed between a sliding plate and a spring plate, which plates comprise openings for motor shafts and motor pinions.
  • the motors can be mounted in a position to operate in relation to the shutter means.
  • a sliding plate and a spring plate are mounted rotationally in relation to a third outer base plate, where at least one of the sliding or spring plates are formed with toothed outer periphery angular section, which angular section co-operates with motor means to rotate the combined spring and sliding plates in relation to the third base plate, which motor means are fixed to the third outer plate.
  • the third plate can comprise guiding rollers, which guiding rollers co-operate with the outer periphery of at least one of the sliding plates or spring plates.
  • This patent application also concerns a system as described in the preamble to claim 7 where the shutter means comprise a front end to delimit the beam of light and the two toothed sides, where the shutter means are slide ably mounted, and where each shutter means co-operate with two motors, which are connected to pinions, which pinions interact with the tooted sides at the shutters, where a first number of motors are placed in a fixed position, where a second number of motors are movable in a sideward direction.
  • the system makes it possible to accommodate change in the actual distance across the shutter when it is rotated by only rotating one of the pinions.
  • a rotation of the shutter is also possible by operating both motors, but at a differ- ent speed. Very fast rotation of a shutter can be achieved by operating one motor in a direction of rotation forcing the shutter forwards where the other motor is rotated in a direction forcing the shutter backwards.
  • This patent application further concerns a method as described in the preamble to claim 8, where the shutter means forms a merged pile, where the shutter means in the pile are operating with the front area placed over the front area of a first neighbouring shutter means and the front area placed below the front area of the second neighbouring shutter means where the shutter means can be individual adjustable.

Abstract

La présente invention concerne un ensemble d'éclairage comprenant au moins une source lumineuse pour générer un faisceau de lumière. Ledit ensemble d'éclairage comprend des moyens de formation de lumière. Lesdits moyens de formation comprennent des moyens d'encadrement (10). Lesdits moyens d'encadrement (10) comprennent des moyens d'obturation (12). Lesdits moyens d'obturation (12) coopèrent avec des moyens de moteur (22, 24, 26, 28, 30, 32, 34) pour déplacer les moyens d'obturation (12) à l'intérieur et à l'extérieur du faisceau lumineux. L'invention a pour premier objectif d'introduire un système, dans lequel les obturateurs (12) sont placés le plus près possible dans le même plan focal. Un autre objectif de l'invention est de réaliser un ensemble très mince pour placer le module d'encadrement près d'ultérieurs moyens de formation de lumière fonctionnant à proximité du plan focal. Un autre objectif est de réaliser une commande directe des obturateurs (12). Les objectifs de l'invention peuvent être atteints si les moyens d'obturation forment un empilage unifié, où les moyens d'obturation (12) dans l'empilage unifié (50) sont placés avec la surface avant placée au-dessus de la surface avant d'un premier moyen d'obturation voisin et la surface avant placée au-dessous de la surface avant d'un second moyen d'obturation voisin. Un degré élevé de liberté de déplacement d'obturateurs dans différentes directions peut être ainsi atteint afin de former un encadrement d'un faisceau lumineux. La formation des moyens d'obturation en un empilage unifié (50) mène à un ensemble très mince, où les bords opérationnels des obturateurs fonctionnent dans le même plan. Ceci peut mener à une limitation uniforme nette d'un faisceau lumineux projeté. Dans un projecteur, l'ensemble mince peut être placé physiquement à proximité d'ultérieurs moyens de formation de lumière, lequel doit fonctionner également près d'un plan de focalisation optique.
