Abstract

The present invention relates to a device for illuminating two mutually angularly arranged surfaces, in particular wall and floor surfaces, with at least one radiator having at least one light source and a deflection optics comprising a reflector and / or a lens, wherein the deflection optics emitted by the light source captures and radiates in the form of a beam on both surfaces, so that in each case a patch is illuminated on both surfaces, wherein the beam comprises an indirect light component reflected by the deflection optics and an unreflected by the deflection optics direct light component, which partially overlap each other. According to the invention, the deflecting optics are configured to limit the unreflected direct light component such that the said direct light component only falls on one of the two mutually angled surfaces and an edge of the surface piece irradiated by the direct light extends along the angular transition between the two surfaces.

Description

  • The present invention relates to a device for illuminating two mutually angularly arranged surfaces, in particular wall and floor surfaces, with at least one radiator having at least one light source and a deflection optics comprising a reflector and / or a lens, wherein the deflection optics emitted by the light source captures and radiates in the form of a beam on both surfaces, so that in each case a patch is illuminated on both surfaces, wherein the beam comprises an indirect light component reflected by the deflection optics and an unreflected by the deflection optics direct light component, which partially overlap each other.
  • For various lighting tasks spotlights can be used, which steer the emitted light cone targeted on the floor or a wall via a deflection optics to illuminate corresponding surface pieces on the floor and / or the wall. Here are spotlights that are mounted at the upper end of a wall adjacent to this, for example, on the ceiling, and illuminate the wall, sometimes referred to as wallwasher. However, radiators radiating downward on a floor surface are sometimes referred to as downlights, whereby such radiators can be integrated, for example, in ceiling panels and combined in matrix-like radiator arrangements.
  • Such emitter assemblies are not only popular for lighting rooms and halls, but can also be used as shop lighting, for example for illuminating showcases, as shelf lighting, kitchen lighting, corridor lighting, stairwell lighting or in conference rooms for table or flipchart lighting. Furthermore, such radiator arrangements can also be installed in electrical appliances such as refrigerators and ovens to illuminate wall and / or bottom surfaces of the appliances.
  • In addition to pure downlight systems, it is sensible and desirable not only to illuminate the floor surfaces, but also to illuminate wall surfaces in order to achieve vertical brightening. In order to achieve an even illumination of the wall surfaces, pronounced, asymmetrical light distributions are necessary, so that not an upper wall section lying close to the radiator radiates much brighter than a wall section lying further down.
  • If surface elements at the bottom and at the adjacent, vertical wall are illuminated by a spotlight at the same time, inhomogeneities regularly occur in the illumination of the surface elements, which usually occur in the region of the wall surface, in particular in the form of brightness edges, which is a more strongly illuminated partial surface piece of one delimit weakly illuminated partial area piece. If it is not easy to achieve an actually homogeneous, uniform light intensity distribution in pure wallwashers, which illuminate only one wall surface piece, which usually requires complex free-form surfaces on the deflection optics, this task is made even more difficult if at the same time floor and wall surface pieces or generally two to each other angularly arranged surfaces are to be illuminated. Basically, it would be considered here to separate these tasks from each other and to use a downlight for the lighting of the floor and a wallwasher for the illumination of the wall surface. However, this is sometimes undesirable for aesthetic reasons and often for cost reasons, so that the problem is to illuminate with one spotlight both floor and wall pieces of surface or generally two mutually angled surfaces evenly without inhomogeneities such as light-dark edges.
  • On this basis, the present invention seeks to provide an improved lighting device of the type mentioned above, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner. In particular, an improved spotlight is to be created, which can illuminate mutually angled surfaces without visible inhomogeneities evenly.
  • According to the invention, said object is achieved by a device according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
  • It is therefore proposed to design the deflecting optics of the radiator in such a way that the direct and indirect light components of the radiation beam are not congruent to one another and insofar as an inhomogeneity in the illumination is permitted, the resulting bright-dark boundary between the illuminated surface only by Indirectlicht and the area illuminated by direct light, however, is banished into the transition between the two angular surfaces and thus made more or less invisible. According to the invention, the deflecting optics are configured to limit the unreflected direct light component such that the said direct light component only falls on one of the two mutually angled surfaces and an edge of the surface piece irradiated by the direct light extends along the angular transition between the two surfaces. The typical brightness edge which is not removed at the transition of the surface area which is irradiated by both direct light and indirect light to the area area which is irradiated only by indirect light, but is displaced into an area in this brightness edge is not noticeable, and thus made almost invisible to the human eye. Due to the fact that there is still a surface piece irradiated only by indirect light and a surface piece irradiated both by indirect light and direct light, the contours of the optically active surfaces of the deflection optics remain manageable in order to achieve uniform light intensity distributions on the respective surface piece. In particular, the wall surface piece, which is sandblasted in the manner of a wall washer, be illuminated uniformly and the necessary highly asymmetric light distribution can be achieved.
  • Said deflection optics can achieve the limitation of the direct light component in the beam bundle with a direct light edge extending along the transition between the angular surfaces both through a reflector and through a lens, it being possible for both a reflector and a lens to be provided. If the deflecting optics uses a reflector which captures light emitted by the light source with at least one reflector surface and transforms it into a beam, the reflector in a further development of the invention can comprise a spoiler edge delimiting the reflector surface, which delimits and directs the uncoordinated direct light component said direct light portion falls only on one of the two mutually angularly arranged surfaces and the edge of the area illuminated by the direct light portion of the sheet extends along the transition between the two angularly arranged surfaces.
  • If, as an alternative or in addition to such a reflector, the deflecting optics has a lens, the light captured by the lens can be totally reflected by corresponding contouring of the lens partially on a lateral surface of the lens or possibly also reflected with appropriate coating, while a direct light component passing centrally through the lens is emitted unreflected from the light exit surface of the lens. In the case of the lens, the direct light component means the light component passing through the lens which is not reflected or totally reflected at the lens panel surface but goes directly from the light entrance to the light exit surface where it is deflected by refraction. The light entry and exit surfaces of the lens responsible for this direct light component can be contoured in such a way that said direct light component of the emitted radiation beam is limited to one of the surfaces, in particular the bottom surface, and the edge of the surface piece irradiated by the direct light propagates along the surface extends said angular transition region.
  • For clarification, it should be noted that the angular transition region between the two angularly arranged surfaces no sharp edge needs to be formed in the sense of the mathematical intersection of two levels, but may also be rounded, as for example in Stuckleisten or formed in fillet moldings to beautify the transition between ceiling and wall or wall and floor is known.
  • In order to prevent larger inhomogeneities arising on the surface to which the direct light component is radiated, the deflection optics can advantageously be embodied such that the surface piece irradiated by the direct light component is substantially completely irradiated by the indirect light component as well. In other words, the indirect light component can also be thrown onto the surface which is irradiated by the direct light component such that the surface pieces respectively irradiated by the direct light component and the indirect light component are congruent or at least approximately congruent to one another on this surface.
  • The deflecting optics can be designed in such a way that the reflected indirect light component falls both on one and on the other of the two angularly arranged surfaces, wherein the indirect light component falling on the one surface and the indirect light component falling on the other surface form a homogeneous transition between the two Both surfaces and / or may have a uniform light intensity distribution across the border of the two areas.
  • The area pieces respectively illuminated on the two surfaces can in principle be contoured differently, for example a rectangular area piece can be illuminated on the wall and a semicircular or triangular area piece can be illuminated on the floor. In an advantageous development of the invention, the deflecting optics can be designed to illuminate a respective rectangular surface piece both on the wall surface and on the bottom surface. On the one hand, the contours of the deflecting optics delimiting the direct light component can be shaped in such a way that the area piece irradiated by the direct light has a rectangular outline contour. On the other hand, the reflecting or totally reflecting surfaces of the deflecting optics can be contoured in such a way that the indirect light component of the radiation beam also irradiates a respective rectangular surface piece on the bottom and the wall or on the two surfaces arranged at an angle to one another.
  • Depending on the lighting task, the spotlight can be arranged or mounted differently. If an upright wall surface and a horizontal bottom surface are to be illuminated by the radiator, the radiator can be arranged at an upper end portion of the wall at a distance therefrom, in particular flush with the ceiling and / or into one adjacent ceiling to be mounted sunk and have a down to the floor and / or the wall directed to the main emission direction, so that the wall surface is abrasive irradiated and the bottom surface is irradiated approximately frontally.
  • Advantageously, the deflecting optics can be designed such that the surface piece lying on the wall surface, which is illuminated by the radiation beam of the radiator, in particular its indirect light component, extends from the bottom to substantially the height of the radiator. If the radiator is mounted in the above-mentioned manner flush with the ceiling or arranged on the ceiling, said surface piece may extend from floor to ceiling of the corresponding room.
  • If the deflecting optics has a reflector, the named reflector can be subdivided into a plurality of reflector segments and / or formed as multi-shelled. Different reflector segments can illuminate different surface pieces. Alternatively, different reflector surface segments can also illuminate overlapping surface pieces, in particular surface pieces which are congruent to one another, for example in that each of the plurality of reflector surface segments illuminates both the entire wall surface piece and the entire bottom surface piece.
  • However, if the reflector surface segments are designed to illuminate different surface pieces, it may be provided in particular that a first reflector surface segment illuminates the bottom surface piece and a second reflector surface segment illuminates the wall surface piece and the transition of the surface pieces irradiated by the two reflector surface segments along the fold or the angular transition extends between the two surfaces. In principle, it would also be possible to provide more than two reflector surface segments, wherein the reflector surface segments may be determined in groups to irradiate, on the one hand, the bottom surface piece and, on the other hand, the wall surface piece. For example, it may be provided in a four-shell reflector that two reflector surface segments together irradiate the wall surface piece to be illuminated, while two other reflector surface segments together illuminate the bottom surface piece. It can be provided that illuminate the wall surface piece reflector segments each illuminate the entire wall surface piece, i. each of the plurality of reflector surface segments provided for illuminating the wall surface can illuminate 100% of the respective sheet on one of the angled surfaces. In principle, however, it would also be possible to provide a lower degree of overlap, for example such that each of the patches only illuminates more than 50% or more than 66% or more than 75% of the total patches on one of the surfaces.
  • If the deflection optics comprise a lens, the lens can likewise be subdivided into a plurality of lens segments, wherein a first lens segment can direct the captured light onto a first of the two surfaces and a second lens segment can direct the trapped light onto a second of the two surfaces, in particular in such a way that that one lens segment irradiates only one surface and the other lens segment only the other surface. Alternatively or additionally, however, it is also possible to provide a plurality of lens segments which irradiate overlapping area pieces or the same, congruent area pieces, it also being possible here for a lens segment to be able to irradiate both a wall surface piece and a bottom area piece. In this respect, the statements made previously for the reflector apply analogously to the lens.
  • In order to achieve a further homogenization of the radiation, to compensate manufacturing and positioning tolerances of the light source and possibly to achieve an improved light color mixture with several differently colored light sources, the deflection optics can be provided with a faceting and / or a microstructuring at their reflecting or totally reflecting surfaces be. For example, microfacets may be provided, which may be formed in the form of flat flats, concave dents or convex pimples, wherein a plurality of such facets may be provided on a photometrically active surface, for example more than 25 or more than 50 or more than 100 such facets a multi-row and / or multi-column arrangement. Alternatively or additionally, other relief-like microstructures such as geometrically regular relief contours such as truncated pyramids, conical elevations or depressions or similar structures may be provided.
  • Said faceting and / or microstructuring may in this case be provided on the reflector surfaces of a reflector or on the totally reflecting lateral surfaces of a lens, it being possible for such a lens also to be provided with a reflective surface coating on which the said faceting or microstructuring may be provided can, wherein alternatively or additionally, however, the said faceting or microstructuring can also be provided on the light entry surface and / or the light exit surface of the lens.
  • In an advantageous embodiment of the invention, the deflection optics is designed to be simply reflective, so that the of the deflection optics captured light is only reflected once before it is blasted onto the surface piece on the wall or on the floor.
  • The invention will be explained in more detail with reference to advantageous embodiments. In the drawings show:
