  • the concave reflector section or sections are advantageously arranged in this way and aligned or alignable that defines one or more spatial areas which are illuminated and / or brightened by the concave reflector sections and are not identical to the spatial area or areas that are affected by the convex Reflector sections are illuminated.
  • this includes the case that at least a light detected by the light reflected from a concave reflector section Room area with the room areas illuminated by the convex reflector sections not or only partially overlapped, that is, by the corresponding concave reflector section an additional area is illuminated.
  • this also includes the case that a portion of the illuminated by the convex reflector sections Area is illuminated by the concave reflector sections more than that The rest, like a spotlight.
  • the projector lights and / or the reflector arrangement or parts thereof fixed or in terms of their location and / or orientation in their respective Holding devices can be adjustable. These cases are not mentioned in this application distinguished; if from a certain location or orientation of components of the Unless otherwise stated, the lighting system is both the case a fixed as well as the case of an adjustable arrangement of the corresponding Elements that can be adjusted to this position / orientation are meant.
  • the invention can provide that the reflector arrangement one or more reflector elements having concave and convex sections that are in a wavy shape Structure are arranged.
  • the central direction of the perpendicular to the Reflecting surface of a concave reflector section different from the central direction is the perpendicular to the reflecting surface of convex reflector sections, which are illuminated by the same projector lamp.
  • the invention can provide that the reflector arrangement with respect to the vertical Direction is spaced from the projector lamp (s) and the angle between the central direction of the light that is radiated by one of the projector lights and is reflected by a concave reflector element to the vertical axis is smaller than the corresponding angle of light that is formed by the convex Reflected reflector sections that are illuminated by the same projector lamp.
  • concave and convex reflector sections are each structurally separate reflector elements.
  • each convex reflector element at least a concave reflector element is adjacent.
  • the invention can provide that the reflector arrangement and the arrangement the projector lights are each rotationally symmetrical about a common axis, in particular the vertical axis.
  • the concave reflector sections reflected light illuminates a room area that is closer the axis of rotation lies as that spatial region which is formed by the convex ones Reflector sections is illuminated.
  • the invention can also provide that the reflector arrangement is a group of mutually spaced concave curved reflector elements and a group of mutually spaced convexly curved reflector elements, wherein the group of concave curved reflector elements and the group of convex curved reflector elements are spaced apart and the individual Reflector elements are arranged so that in a projection in the distance direction the concavely curved reflector elements the spaces between convexly curved Essentially cover reflector elements.
  • the projector lights shine from the bottom up and the concave reflector elements over the convex reflector elements are arranged, more generally that the concave reflector elements further from the projector lights are removed than the convex reflector elements.
  • the invention can provide that the beams of the projector lights in the area the group of convex reflector elements are focused.
  • the invention can provide that the reflector arrangement at least partially made of wing-like reflector elements projecting radially with respect to the axis of rotation is formed.
  • the reflector arrangement has reflector sections with different radii of curvature.
  • the convex reflector sections a different, preferably smaller radius of curvature have than the concave reflector sections.
  • Reflector sections or reflector elements with different widths can also have different radii of curvature to diffuse the light evenly.
  • the invention can provide that the concave and convex reflector elements include different angles with the axis of rotation.
  • one or more of the concaves and / or the convex reflector sections with a grid-like structure local Bulges is provided.
  • the invention can provide that the reflector arrangement and the projector lights are attached to a mast and the beam direction of the projector lights essentially is parallel to the longitudinal axis of the mast.
  • the invention can provide that the orientation of reflector elements about its radial axis and / or the inclination of reflector elements to the axis of rotation is changeable.
  • the convex reflector sections that have a large Can cover room area to achieve basic lighting, which in limited Through the concave reflector elements or reflector sections reflected light is efficiently amplified or supplemented.
  • the concave reflector sections even a small amount of light can be used efficiently are, so that it is particularly possible to design the reflector arrangement so that the majority of the light illuminated by a projector lamp from the convex reflector section is reflected and the "residual light" is used by the concave sections becomes.
  • convex and concave reflector elements can be used. According to the state of the art were used with spaced convex reflector elements, as described in AT 86670 B are described, the light losses in the spaces between these reflector elements compensated for by the fact that convex reflector elements are also in a further plane were ordered. Through the use of concave reflector elements in a second plane it is possible to reflect the Focus light so that the focus is in or near the plane of the convex reflector elements lies so that all the light that passes through the spaces between the convex reflector elements passes through these gaps essentially is completely reflected back, so that a higher luminous efficiency is possible is.
  • the lighting system according to the invention also allows a corresponding one Embodiment, without increasing the number of indicator lights in one Illuminated area a partial area by concave reflector sections according to Art to illuminate a spot more strongly, for example a competition area in one Sports hall or the like
  • Fig. 1 shows schematically an example of a first embodiment of the invention, at which the reflector elements are arranged essentially in one plane.
  • Each projector lamp 3 emits a group of reflector elements on, the beam of the projector lights preferably on the convex Reflector elements 7 is focused or concentrated.
  • the concave reflector elements 9 catch the light passing by the convex reflector elements 7 and reflect this focused back to the ground.
  • the convex reflector elements 7 are preferably inclined towards the mast and illuminate the area away from the mast while the concave reflectors 9 are essentially horizontal and the area near the mast illuminate.
  • the radius of curvature of the concave curved reflector elements 9 and the convexly curved reflector elements 7 can be different.
  • the width of the Reflector elements can vary; in particular, the width of the reflector elements 7 be larger than that of the reflector elements 9, so that a larger proportion of light from the convex reflector elements 7 is reflected.
  • the beam of a projector lamp can be used Detect several convex reflector elements 7. In a preferred embodiment the curvature is adjusted to the width of the reflector elements 7 and 9, that the light is scattered evenly.

More precise are on a mast 1 with launcher lights 3 in a first level a wreath held on a support plate 105 of convexly curved reflector elements 107 and in a second one, towards the mast end towards the plane, a ring of concavely curved rings held on a support plate 108 Reflector elements 109 are provided. In every wreath of reflector elements 107 and 109, the reflector elements are spaced apart from one another in the circumferential direction, wherein the two rings of reflector elements are offset from one another such that the concave reflector elements 109 over the spaces between the convex ones Reflector elements 107 are.
