Definitions

  • the invention relates to a luminaire for illuminating building surfaces or building part surfaces, according to the preamble of claim 1.
  • the known lamp has a reflector element made of aluminum, which is formed substantially parabolic.
  • the reflector element is made of an aluminum blank, which is pressed in rotation against a pin (male). It has after performing the pressing an inner side, which is formed as a die, and on which the male has imaged.
  • the known reflector element has a plurality of segments which each comprise a substantially planar surface. Both when viewed in the circumferential direction and when viewed from an edge region of the reflector element toward its apex region, a row of adjacent segments in each case form a polygonal line.
  • the present invention seeks to further develop the known lamp such that a simplified construction is possible.
  • the invention achieves this object with the features of claim 1, in particular with those of the characterizing part, and is accordingly characterized in that the segments each have a curved surface toward the interior, wherein the reflector element has a distance between its apex region and its free edge region, and a light exit opening, in particular a substantially circular light exit opening, comprising a first diameter, wherein the reflector element is interchangeable by a second reflector element with the same distance and with the same diameter, which has segments which have a different curved surface to the first reflector element.
  • the principle of this invention is therefore essentially to provide a first reflector element and a second reflector element with the same external dimensions or dimensions, ie with the same distance and with the same diameter.
  • the first and the second reflector element are therefore interchangeable.
  • first and the second reflector element Attach mounting fixtures or mounting grooves. Both the first reflector element and the second reflector element can be attached to the same luminaire, preferably with the same fastening means.
  • the two reflector elements on differently curved surfaces which differ in particular with respect to their radii of curvature.
  • the first reflector element can produce a first emission characteristic for the luminaire, which corresponds for example to that of a conventional spotlight
  • the second reflector element can provide a second emission characteristic different from the first emission characteristic, which corresponds to that of a conventional floodlight.
  • the emission characteristic of the luminaire can be completely changed in this way, without any changes must be performed on the lamp. It is sufficient to replace the reflector element. This is possible by calculating and providing only different radii of curvature for the curved surfaces.
  • the principle according to the invention offers the possibility of fundamentally simplifying the hitherto required complex construction of respectively different luminaires for different emission characteristics.
  • the reflector elements have to be individually different.
  • the luminaire can otherwise be made completely identical with regard to its receiving space for the reflector element, with respect to the luminaire housing and with regard to the luminaire-side fastening elements for the reflector element.
  • the storage of light parts can be simplified in this way fundamentally.
  • the emission characteristics of an already built-in, that is permanently mounted on the job light can be changed by replacing the reflector element if necessary.
  • the luminaire according to the invention differs from the state of the art in particular in that the segments each have a surface curved toward the interior.
  • a peculiarity therefore consists essentially, instead of using segments with substantially planar surfaces, which provide for a reflection of the outgoing light from the lamp in a conventional manner, now provide curved surfaces that fan out the individual light components or bundles targeted and thus uniform can. In this way, it succeeds, the luminance on the Reflect reflector surface by distributing on a variety of segments.
  • a minimization of scattered light components is possible because the curved, in particular substantially spherically curved, segments can be particularly precisely predicted and correspondingly accurately formed.
  • each segment is preferably curved twice, and thus has a first and a second radius of curvature.
  • the emission characteristics of the luminaire can be greatly influenced. Smaller radii lead to a greater fanning out of a light beam and are therefore to be used preferably when the luminaire is to be used as a floodlight, thus a large surface area of a building part is to be illuminated. Larger radii of curvature fanned parallel beams of light less, and are therefore preferably used when the lamp is to be used as a spot light, and quite a narrow limited area, eg circular area, a building surface should illuminate.
  • At least one lamp can be arranged in the interior of the reflector, wherein light from the lamp at least partially reaches the surface of the building or the part of the building to be illuminated only after reflection or scattering on the inside of the reflector element, said that direct light components from the lamp are also directly illuminated on the lamp Building surface can reach.
  • significant light components that is to say the predominant portion of the luminous flux emitted by the lamp, initially strike the inside of the reflector element.
  • a building wall, a building ceiling or a building floor is referred to as the building surface or part of the building, and in the case of outdoor luminaires it is, of course, also possible to illuminate path areas or road areas.
  • the luminaire according to the invention is stationary, preferably attached to a building surface or a building part surface, but alternatively also to a mast or the like.
  • an object arranged on a building surface e.g. a work of art, viewed.
  • the luminaire according to the invention for illuminating building surfaces or partial building areas can therefore also serve for object lighting, which is of interest in particular for luminaires designed as spot luminaires.
  • the segments according to the preamble of claim 1 all such segments are understood, which are arranged, that are arranged according to a certain pattern or grid relative to each other.
  • the segments can be arranged in any grid.
  • grid is required to achieve the desired radiation characteristics of the luminaire.
  • a grid is used, in which the segments are arranged substantially circular in the circumferential direction, wherein the number of segments of a circular ring as a function of the distance of the circular ring from a vertex area of the reflector element does not change but is constant. Consequently, there is also the possibility of arranging the segments as viewed in the direction from a region of the edge of the reflector element towards its vertex region essentially along a straight line, that is to say linearly.
  • a lamp in the region of a focal point of the reflector element can be arranged, that is placeable. This allows a precisely predeterminable Ausstrahl characterizing the luminaire.
  • a focal point near arrangement of a lamp is particularly advantageous if the reflector element is curved substantially parabolic.
  • other shell-shaped basic shapes for the reflector element may be considered.
  • several lamps can be arranged within the reflector element. It is crucial that the light sources are arranged at least near the focal point.
  • the reflector element is formed substantially rotationally symmetrical. This allows a particularly simple design and manufacture of the reflector element and a particularly homogeneous illumination of the building surfaces.
  • the surface is curved twice.
  • the surface has a first curvature with a first radius and a second curvature with a second radius.
  • the surface of each Segmentes is thus formed substantially spherical.
  • this is not necessarily the section of a spherical surface, but a domed in space surface, which is curved along two different radii of curvature.
  • a spherical surface would only be considered as a special case if the first radius and the second radius were the same. This special case is covered by the invention.
  • the emission characteristic of the luminaire can be determined very precisely beforehand. In particular, so that the building surface or building part surface can be illuminated in a particularly homogeneous.
  • the first radius and / or the second radius are different depending on the distance of the segment to a peak region of the reflector element. This allows a particularly accurate predetermination of the radiation characteristics of the lamp.
  • two segments are arranged immediately adjacent to each other.
  • the entire inside of the reflector element is thus composed of the surfaces of the individual segments. This reduces the luminance on the reflector surface and minimizes the stray light components.
  • a plurality of groups of annularly arranged segments are arranged between a vertex region of the reflector element and a light outlet opening of the reflector element. This allows a particularly homogeneous illumination of the building surface. moreover is the emission of the lamp in this way in a particularly simple manner previously determined.
  • the segments are arranged substantially linearly relative to the curved inside of the reflector element.
  • the segments are thus arranged substantially along a straight line when a viewer looks into the interior of the reflector element substantially along the axis of rotation of the reflector element or along its longitudinal central axis.
  • the segments are arranged along a curved path which follows the course of the inside of the reflector element. This curved path connects the apex region of the reflector element with the free edge region of the reflector element by the shortest route.
  • the size of the segments increases from a vertex area of the reflector element to a light exit opening of the reflector element. This allows complete equipment of the inside of the reflector element with segments.
  • the entire inner surface of the reflector element between the light exit opening and the apex area is occupied by segments.
  • the segments thus occupy the entire inner side of the reflector element from its free edge region up to the apex region, that is to say directly up to an opening through which the lamp or a base for the lamp is inserted.
  • the number of segments in the circumferential direction is constant regardless of the distance of the segment from the apex region of the reflector element. This allows a particularly homogeneous illumination of the building surface or the building part surface.
  • a collar is arranged in the region of an edge of the reflector element. This allows a particularly simple attachment of mounting holes.
  • the reflector element is designated in its entirety in the figures with 10, wherein for the same parts or elements of the two different embodiments of the Figures 1 and 2 on the one hand and the FIGS. 3 to 6 on the other hand, for the sake of simplicity, the same reference numerals, partially with the addition of small letters are used.
  • the Figures 1 and 2 show a substantially parabolically curved reflector element 10, which has a vertex area 11 and a free edge region 12.
  • the axial distance between the apex region 11 and the free edge region 12, ie the height or peak height of the reflector element 10, is in Fig. 2 designated h 1 .
  • the free edge region 12 of the reflector element surrounds a substantially circular light exit opening 20 of the diameter d 1 . This thus corresponds to the inner diameter d 1 of the reflector element 10 at its widest point.
  • the reflector element 10 is expanded radially outwards and has a flange-like collar 13.
  • a flange-like collar 13 On the flange-like collar 13, as best of Fig. 1 can be seen, two groove-like edge recesses 14a, 14b arranged, represent the mounting holes.
  • fasteners such as screws that push through these edge recesses 14 a, 14 b partially, the reflector element can be attached to a non-illustrated luminaire housing a lamp, also not shown.
  • the reflector element 10 is arranged for this purpose in a conventional manner in an interior of the lamp. In the assembled state of the lamp is typically the respect Fig. 2 upper side 30 of the flange-like collar 13 on a light housing-side contact surface, so that the flange-like collar 13, and thus the entire reflector element 10, can be clamped against this contact surface.
  • an opening In the region of the vertex 11 of the reflector element 10 there is an opening, not shown in the figures, which is typically mounted in the form of an opening about the longitudinal central axis I of the reflector element 10 in the region of the vertex 11 thereof.
  • the opening can be achieved, for example, by punching out or cutting out the apex area 11.
  • a lamp is pushed through, so that the lamp 10 in the assembled state in the interior 21 of the reflector element 10, preferably approximately in the region of in Fig. 2 merely indicated sketched focal point 22 is located.
  • the reflector element 10 has on its inside 27 a plurality of segments.

  • the segments extend from the free edge region 12 of the reflector element 10 all the way to the region of the vertex 11 FIG. 1 results, the segments are arranged along straight lines 18. In total, there are, according to the number of segments in the circumferential direction, eighty different radiant lines 18, which, when viewed in the direction of the Fig. 1 extend from the apex 11 of the reflector element 10 toward its free edge 12. This results in a spider-web-like structure or a spider-web-like grid.

  • Fig. 1 makes it clear that the reflector element 10 has a total of a concentric arrangement of annular groups of segments.
  • a group of eighty segments immediately adjacent the free edge 12 of the reflector element 10 forms an annular group 29a of segments.
  • Each group of segments has eighty segments.
