Definitions

  • a generic reflector comprises a light entry end, a light exit end with at least one substantially quadrangular light exit opening, an optical axis, and a reflector surface extending between the light entrance end and the light exit end, the reflector surface defining a polygon in a plane perpendicular to the optical axis.
  • Generic reflectors come u.a. in recessed spotlights, but also in other lights used.
  • the light exit opening is aligned concentrically to the optical axis of the reflector, and the optical axis is substantially completely surrounded by the reflector surface.
  • reflectors with a rectangular reflector surface are often used, wherein the four side surfaces of the reflector in the direction between the light entry end and the light exit end are curved in particular parabolic.
  • the reflector surface at the corners of the cross-sectional area is not continuous into one another.
  • the angle between the faces of the reflector surface is 90 °. This leads to inhomogeneities of the illuminance in the emitted cone of light.
  • the emitted light cone has a light intensity with sharp edges, wherein the shape of the light cone substantially corresponds to the shape of the reflector surface, if no aperture is arranged at the light exit end of the reflector or in the direction of the emitted light cone.
  • the inhomogeneities caused by the edges now cause the emitted light cone not a uniform illuminance, but areas with increased or decreased illuminance.
  • the invention offers the advantage that a twisted surface of revolution is created by the rotating polygon.
  • the inhomogeneities generated along the edge are thus no longer superimposed in one area of the emitted cone of light, but are distributed over several emission directions and are superimposed by light beams which have been reflected off the edges of the reflector surface.
  • the luminous intensity of the emitted light cone becomes more homogeneous overall.
  • the polygon also changes shape and size between the light entry end and the light exit end.
  • the corners of the rotating polygon define spirals on the reflector surface.
  • the polygon has more than four corners, and at the light exit end, a first transition region is formed, in which the polygon merges continuously into the shape of the light exit opening. Increasing the number of corners increases the angle between two adjoining surface sections, resulting in a reduction in the inhomogeneity of a corner. In the first transition region, the polygon can continue to rotate about the rotation axis.
  • the axis of rotation is also perpendicular to the plane of the polygon.
  • the reflector surface is a reflective coating of a reflector shell. It is also an alternative possible that the reflector shell consists of a reflective material and its inner, the optical axis facing surface is formed as a reflector surface.
  • the axis of rotation and the optical axis coincide. This makes it possible to realize symmetrical light cone shapes in a particularly simple manner. However, it is alternatively conceivable that the rotational axis and the optical axis do not coincide for the realization of other light cone shapes.
  • the light exit opening is square.
  • the light exit opening has a different quadrangular shape.
  • the quadrangular light exit opening may have curved edges. This allows the reflector to adapt to lighting tasks or design aspects.
  • the present invention further provides an arrangement with at least two reflectors according to the invention, wherein the light exit openings of the reflectors are arranged adjacent, and the rotations of the polygons of adjacent reflectors have an opposite direction of rotation.
  • the invention further provides a luminaire with a reflector according to the invention and a light source, wherein the light source is arranged at the light entry end of the reflector and comprises at least one LED.
  • the reflector according to the invention is particularly advantageous for lights with LEDs.
  • the edges of the polygon are curved.
  • the reflector can be easily adapted to lighting tasks.
  • the edges are convexly curved. This further improves the imaging properties of the reflector.
  • the outside of the reflector shell may be curved in particular convex.
  • the polygon is a point-symmetric polygon, and the center of symmetry lies on the axis of rotation. Accordingly, the polygon rotates about its center of symmetry. This makes it particularly easy to realize symmetrical light cone shapes.
  • the polygon is a point-symmetrical octagon with a 4-fold rotational symmetry.
  • even a small angle of rotation already has a particularly advantageous effect on the homogeneity of the illuminance, while at the same time the production costs and the number of discontinuities in the reflector surface are kept low.
  • the polygon rotates along the entire reflector surface between the light entry end and the light exit end.
  • the rotation of the polygon has a particularly effective effect on the homogeneity of the illuminance of the emitted light cone. If the reflector has a first transition region at the light exit end, the polygon can rotate to the beginning of the transition region or even within the transition region to the light exit end.
  • the angle of rotation swept from a corner of the polygon in a plane perpendicular to the axis of rotation by the rotation between the light entry end and the light exit end is greater than 15 °. From this angle of rotation, the rotation has a particularly advantageous effect on the homogeneity of the illuminance.
  • the angle of rotation of each corner is substantially 360 ° divided by the number of corners of the polygon.
  • the inhomogeneities of a corner are distributed over an area that extends to the starting point of the inhomogeneity caused by the next corner. At this angle of rotation so no inhomogeneities are available.
  • the reflector surface is parabolic in a plane parallel to the optical axis between the light entry end and the light exit end.
  • the reflector additionally has the refractive properties of a parabolic mirror. In this embodiment, it is particularly easy to realize parallel light cones.
  • the reflector has a light inlet opening at the light entry end.
  • a light source can be arranged in a particularly simple manner in the reflector, or introduce light in a particularly simple way in the reflector.
  • the reflector is flattened at the light entry end and the reflector surface opens at the flattened light entry end into a base surface. This makes the reflector very compact.
  • the base surface formed by the flattened end, into which the reflector surface opens, can have the shape of the polygon. Most preferably, the base and the plane spanned by the light exit opening are parallel.
  • the base surface is formed substantially quadrangular, and at the light entry end, a second transition region is formed, in which the polygon merges steadily into the shape of the base surface.
  • the shape of the base surface may have curved edges and / or the shape of the light exit opening. This results in a particularly aesthetic overall impression.
  • the polygon in the second transition region can continue to rotate about the axis of rotation.
  • the light exit opening and the base are substantially square in shape
  • the polygon is a point symmetric octagon having a 4-fold rotational symmetry
  • the reflector surface being formed to lie in a plane parallel to the optical axis between the light entry end and the Light outlet end parabolic and the polygon between the base and the light exit opening along the entire reflector surface rotates such that the corners of the base pass into those corners of the octagon, which open at the centers of the edges of the light exit opening, and the centers of the edges the base surface in those corners of the octagon, which open in the corners of the light exit opening.
  • two different spiral shapes are defined on the reflector surface by the corners of the rotating octagon, with the first spirals extending from the centers of the corners of the base to the centers of the edges of the light exit aperture and the second spirals from the centers of the edges of the base extend the corners of the light exit opening.
  • edges of the base surface and the edges of the light exit opening are aligned parallel to each other. This results in a particularly aesthetic reflector.
  • the reflector is produced by means of injection molding.
  • the reflector according to the invention can be produced particularly easily.
  • the reflector shell is at least partially convex. As a result, the demolding of the reflector during injection molding is simplified.
  • a reflector body is first produced by means of injection molding and then applied to the inside of the reflector shell to form the reflector surface, a reflective layer.
  • the reflector according to the invention can be produced in a particularly simple and cost-effective manner.
  • the arrangement comprises four reflectors, which are arranged in a rectangle, wherein the opposite reflectors are of the same design.
  • the superposition of the invention homogeneous light cone of the individual reflectors results in a particularly homogeneous emitted light beam for the entire arrangement.
  • the luminaire comprises a diffuser element.
  • the diffuser element can be designed, for example, as a cover glass be and be arranged at the light exit opening. As a result, the illuminance of the emitted light cone can be further homogenized.
  • the Figures 1 and 2 show a reflector 1 according to the invention with a light entry end 2, a light exit end 3 and a reflector shell 7, which extends between the light entry end 2 and the light exit end 3.
  • a light exit opening 6 is formed at the light exit end 3.

  • the octagon 11 rotates along the entire reflector surface 4 between the light entry end 2 and the light exit end 3 about an axis of rotation R, wherein the axis of rotation R coincides with the optical axis O.
  • the octagon 11 also rotates within the first transition region 12 and the second transition region 13.
  • the edges of the rotating octagon 11 define on the reflector shell 7 and on the reflector surface 4 spirals 9, 10.
