  • the reflector device has at least two reflector sections spaced apart in a longitudinal direction, which are each formed by reflector surfaces that are concavely curved in at least two directions of curvature, with the at least two reflector sections being oriented towards the side wall of the carrier part, and with one lamp unit each being assigned to one of the at least two reflector sections is.
  • the pamphlet EP 3 217 070 A1 discloses a lighting device for illuminating a surface section of a wall with at least three spotlights, each of which has a point light source and a reflector associated with the light source, the reflector essentially completely capturing the light from the associated light source and throwing it onto the surface section to be illuminated, and off is composed of two shell halves, each of which shell halves distributes the respectively captured light over the entire area to be illuminated.
  • the reflector is essentially mirror-symmetrical to a plane of symmetry and the lighting device has a mounting device for the radiators, the at least three radiators being arranged in the mounting device in such a way that the plane of symmetry of at least one reflector is tilted relative to each plane of symmetry of all other reflectors.

  • the present invention relates to a lamp having an integral lamp housing with a lighting arrangement for defined light emission (in particular on a lateral side of the lamp).
  • the lighting arrangement has a shelf washer arrangement with a first light source and first optics assigned to the first light source, in order to deflect light emitted by the first light source in such a way as to generate an illuminated surface (preferably with a defined illuminance distribution) on the side of the luminaire in relation to a vertical surface; therefore to fulfill a wallwasher or shelfwasher function.
  • the lighting arrangement also has a spot arrangement with a second light source and second optics assigned to the second light source, in order to deflect light emitted by the second light source in such a way as to illuminate a partial area of the lighting surface with greater illuminance than the shelf washer arrangement.
  • greater illuminance means that the spotlight arrangement is used to accentuate the sub-areas of the illuminated area illuminated by the shelf washer arrangement compared to the rest of the illuminated area, i.e. these sub-areas are optically emphasized by an overall increased illuminance. This can for example, due to an overall higher light intensity of the spot arrangement compared to the shelf washer arrangement or simply due to greater illuminance due to the overlapping of the illuminated area and the partial area.
  • an “integral lamp housing” is to be understood in particular as a coherent housing consisting of a single integral body or several functionally connected parts, which brings together the entire lighting arrangement in one component and can therefore be handled as a whole.
  • a lateral side of the lamp is to be understood as meaning that, with respect to a vertical line passing through the lamp housing, a light emission is directed laterally away from this vertical line; this obliquely and/or orthogonally.
  • shelfwasher is basically to be understood as meaning a wallwasher that is designed in particular for shelf lighting.
  • shelfwasher and “wallwasher” are to be used synonymously in the context of the present invention.
  • the lamp according to the invention With the help of the lamp according to the invention, it is thus possible to provide the functions of a large-area wallwasher or shelfwasher lighting and an accent-setting spot lighting in an integrated component, which ultimately means that the installation effort for a corresponding lamp is significantly reduced compared to a comparable lighting arrangement with numerous individual lights to achieve a comparable lighting function .
  • the integrated provision of the two lamp arrangements in the common lamp housing also enables a defined relative assignment and, if necessary, alignment of the same to one another, so that the effort involved in setting and aligning the individual lamp arrangements is significantly reduced or even eliminated.
  • the lamp housing can extend longitudinally along a preferably horizontally oriented longitudinal axis (ie a longitudinal axis of the lamp housing or the lamp). This preferably transverse to a direction of the defined light output. Since the illumination surface is provided on the side of the luminaire, the illumination surface is then consequently a vertical surface whose second orientation is parallel to the longest extent of the luminaire, ie to its longitudinal axis. Consequently, the light function can be arranged in a longitudinally stretched distribution and thus one over one defined longitudinal range provided light output can be made possible. Thus, the effectiveness of the lights can be further increased. In addition, a corresponding lamp with preferably large-area light emission can be designed in a comparatively compact manner. The elongate configuration thus enables a corresponding lamp to be installed as flat as possible, for example on a ceiling of a warehouse or supermarket aisle.
  • the shelf washer arrangement and/or the spot arrangement of the lighting arrangement are preferably arranged next to one another in a row and are preferably distributed parallel to the longitudinal axis.
  • the lamp housing has a support housing and an arrangement housing which is provided so as to be movable relative to the support housing (e.g. pivotable, preferably in an up-down direction).
  • the shelf washer arrangement and the spot arrangement are arranged at least partially in the arrangement housing (and otherwise of course then in the carrier housing). In this way it is possible to correspondingly adjust the components of the lighting arrangement provided in the movable arrangement housing and thus preferably set the light emission according to the desired light emission direction. This can be due to different circumstances of the place of use Shelving areas that are at different distances can also be specifically illuminated. It is also possible in this way to set corresponding spot areas within the radius of movement of the arrangement housing (e.g. a pivoting movement for adjustment up and down).
  • the lamp housing it is also conceivable for the lamp housing to have several arrangement housings that can be moved relative to one another with respect to the carrier housing and preferably also with respect to one another, with the respective arrangement housing having part of the shelf washer and/or spot arrangement. In this way, the different components of the lighting arrangement can also be adjusted individually.
  • the assembly housing can be pivotable about a pivot axis. This preferably in such a way that the light emission direction or an average light emission direction of the deflected light can be changed with respect to a vertical, so that the light emission can be varied with respect to an up/down direction in space (ie in height).
  • the pivot axis can preferably be aligned parallel to the horizontal or to the longitudinal axis. In this respect, the height of the lighting arrangement can be varied with regard to its direction of light emission, and the luminaire can thus be individually adapted to the given framework conditions in a simple manner.
  • the lamp housing or, if present, the arrangement housing can have a preferably substantially vertically oriented projection edge, on which the lighting means (ie preferably the first and second lighting means; or just a part of them) are provided laterally covered to the outside.
  • the lighting means are thus provided in a concealed manner behind this projection edge, so that a direct view of the lighting means can be avoided, which consequently enables a preferred glare reduction for passers-by.
  • the protruding edge preferably extends downwards from an upper area of the arrangement housing, so that the lighting means are then provided on this protruding area and can radiate towards the center of the luminaire onto the first or second optics provided there, in order to thus illuminate the defined area and the corresponding partial areas to create.
  • the light emission opening of the lamp or of the associated lighting arrangement is then preferably below the projection edge intended.
  • the area to be illuminated or the illumination area is then generally located laterally beyond the projection edge with respect to the illumination arrangement.
  • the first optics can be or have a first reflector, preferably a free-form reflector. This is designed to achieve a desired light output.
  • the reflector is preferably matched in a defined manner to the light output of the illuminant.
  • the first reflector can preferably be of simple asymmetrical design, for example symmetrical to the right and left with respect to a vertical axis of symmetry and asymmetrical from top to bottom.
  • the shelf washer arrangement can be designed in such a way that it produces a defined and preferably uniform illuminance distribution (on) the illuminated area. This can be implemented, for example, by setting and distributing the light output or light intensity in such a way that even when the luminaire is mounted on a ceiling and the light output is therefore (slightly) inclined downwards to illuminate shelves arranged diagonally below it, the illuminance on the area to be illuminated is evenly distributed.
  • the second optics can also be or have a (second) reflector, preferably a free-form reflector.
  • the shape is adjusted accordingly to the illuminant in order to achieve the desired defined light output and here in particular the accentuation of the partial area in the illuminated area.
  • the second reflector is preferably of multiple asymmetrical design.
  • the corresponding design of the second reflector results from the desired distribution of the illuminance and the arrangement and design of the light source; For example, the arrangement of LED chips and the corresponding design of an associated lens.
  • the spot arrangement can be designed in such a way as to generate a defined illuminance distribution of the partial area. Preference is given here to an illuminance that increases towards a subsection of the subarea, for example towards a center of the subarea. For example, it is conceivable that one or more specific sections (e.g. in the center of the section) are to be particularly emphasized. Of course, it is also conceivable for the partial area to have a uniform illuminance distribution, if this is desired.
  • the illumination area can have a substantially rectangular shape.
  • the shape of the lighting surface should be designed in accordance with essentially conventional shelf surfaces and thus enable lighting that is as large as possible and therefore effective.
  • the illumination surface can also have any other shape, for example by designing the shelf washer arrangement accordingly.
  • the portion may be rectangular or oval or any other desired shape and most preferably is elongate with respect to a vertical; e.g. upright, oval or rectangular. In this way, appropriate goods or product areas can be accentuated as specifically as possible via the shelf height.
  • the shelf washer arrangement can have a plurality of first lamps, each with an associated first optic (preferably in a ratio of 1:1), in order to deflect light emitted by the first lamps via the respective first optic in such a way as to jointly generate the illuminated surface on the side of the lamp. Due to the provision of a plurality of first light sources with associated first optics of the shelf washer arrangement, it is thus possible to generate the widest possible illumination area, while the size of the corresponding first individual optics can be kept to a minimum. Alternatively, a larger illumination area can also be achieved with a first optic that is then dimensioned comparatively larger, which in turn would result in a reduced total number of parts.
  • the spot arrangement can also have a plurality of second light sources with associated second optics (preferably in a ratio of 1:1) in order to deflect light emitted by the second light sources via the respective second optics in such a way as to illuminate one or more partial areas of the illuminated area with greater illuminance than the shelf washer arrangement to illuminate. It is thus possible here to generate a corresponding number of sub-areas or sub-areas of different sizes as desired and thus to provide any desired accentuation of the illuminated area by means of the spotlight arrangement.
  • the first optics and the second optics are preferably arranged in a row next to one another. More preferably, the first optics and the second optics are distributed parallel to the longitudinal axis. In this way, a particularly compact lamp with good light distribution at the same time due to the Requirements for the lighting adapted distribution of the components allows.
  • the second optics preferably laterally enclose the first optic(s); thus form a sandwich structure; this preferably with respect to or along the longitudinal axis.
  • two second optics lying on the outside (with respect to the longitudinal axis) can enclose several (for example two, four, six, eight or any other desired number) first optics.
  • the first optics can thus easily image/generate the illuminated area, while the second optics can then be aligned laterally from the outside to the illuminated area in order to illuminate the corresponding partial areas of the illuminated area.
  • part of the second optics can also laterally enclose part of the first optics; this preferably along or with respect to the longitudinal axis. There are no limits here to the light or its configuration as a result of the invention.
  • At least two of the second optics can be mirrored and this can preferably be arranged with respect to a plane that is orthogonal to the longitudinal axis. This preferably in such a way that these second optics are inclined towards one another.
  • the second optics and also, if necessary, the first optics can be inclined in any desired way; this preferably with respect to a plane orthogonal to the longitudinal axis.
  • the optics can be aligned in a defined manner in order to form any desired illumination area and the sub-areas thereof.
  • the lighting arrangement can also have a room lighting arrangement with a third light source, in order to emit light emitted by the third light source, preferably essentially downwards below the luminaire, preferably transversely to the longitudinal axis and downwards obliquely or orthogonally with respect to a horizontal.
  • a possibility is also provided, for example, to illuminate aisles located below the lamp with, for example, a weak ambient light in such a way as to allow sufficient light for passers-by (for example customers in a supermarket) to move around safely.
  • the room lighting arrangement can also have third optics, such as diffuser optics, in order to optically influence light emitted by the third illuminant, for example to scatter it diffusely and/or preferably to emit it narrowly along the longitudinal axis of the lamp housing.
  • the third optic should thus make it possible to achieve a desired light output. This prefers to create ambient lighting or other desired room lighting.
  • the third optics can also have other light-influencing features, elements, structures and/or materials. For example, defined conversion particles are conceivable in order to convert the light from an LED as a light source into light of a different wavelength.

  • the lamp housing 2 or the arrangement housing 21 can have a preferably substantially vertically oriented projection edge 22, on which the lamps 40, 50 are provided laterally covered to the outside. In this way, it can be prevented that a passer-by from the outside can see the lamps 40, 50 directly or at least only to a limited extent. In this way, the light sources 40, 50 can direct their light onto the optics 41, 51 without hindrance, which enables effective light emission with simultaneous preferred glare control.
  • the lighting assembly 3 can also be a room lighting assembly 6 with a have third illuminants in order to emit light emitted by the third illuminant downwards below the lamp 1, preferably transversely to the longitudinal axis X.
  • this can also be be illuminated as desired, so that the lamp can also have a corresponding integrated room lighting or ambient lighting function in addition to the wallwasher or shelfwasher function and the spot function.
  • the room lighting arrangement 6 can also have third optics 61, such as a diffuser optics here, in order to optically influence light emitted by the third illuminant and, for example, to diffusely scatter it here.
  • third optics 61 such as a diffuser optics here, in order to optically influence light emitted by the third illuminant and, for example, to diffusely scatter it here.
  • other third optics 61 with correspondingly different optical functions are also conceivable.
  • the lamp 1 can preferably have two lighting arrangements 3 (or, of course, more). In the embodiment shown here with two lighting arrangements 3, these are particularly preferably arranged to radiate in opposite directions or with respect to a vertical axis-symmetrically. Other (relative) light emission directions are also conceivable. If there are more lighting arrangements 3, the light emission direction of the same can be provided arbitrarily.
  • the carrier system 5 can be a mounting rail system, for example, so that when the lamp 1 is fastened by means of the mounting sections 23, mechanical and electrical contact can be provided at the same time.
  • connection options such as DALI
  • light control can also be made possible in a simple manner.
  • the lamp 1 can also have a lamp controller (not shown) in order to optionally control the first lamp 40 and/or the second lamp 50 and/or preferably, if present, the third lamp 60 and, for example, switch it on or off or dim it. If there are several lamps 40, 50, 60, they can be controlled (eg dimmed) individually or in part together. In particular, it is conceivable that all lamps 40, 50, 60 of a corresponding arrangement (i.e. shelf washer arrangement 4, spotlight arrangement 5, room lighting arrangement 6) are controlled together, with individual control of the lamps 40, 50, 60 of a respective arrangement 4, 5 , 6 is conceivable.
  • a lamp controller not shown
  • a lighting arrangement can be provided which comprises several of the lamps 1, so that the several lamps 1, by means of their shelf washer arrangements 4, produce a common arrangement lighting area B1 composed of the lighting areas B, within which the accentuation of the corresponding partial areas T is achieved.
  • the illumination areas 5 can preferably adjoin one another or overlap in order to form a continuous arrangement illumination area B1.
  • the room lighting arrangements can then illuminate the aisle over a large length along an aisle area below the lights 1 .
  • the lights 1 are preferably arranged in a row one behind the other. They can be provided directly adjacent to one another or spaced apart.
