    The present invention relates to a lamp, in particular a lamp for illuminating aisles, such as aisles in which sales goods are stored, for example on shelves.
    In stores such as supermarkets, clothing stores,
    Hardware stores, or in warehouses, the goods are usually stored and offered on shelves or similar storage facilities. The storage facilities are usually arranged in a corridor so that customers can view the goods from the aisles and take them out of the storage facilities. To illuminate the aisle itself and the goods, lights are usually arranged above the aisles. Since both the arrangement of the goods in the storage devices and the arrangement of the storage devices themselves change frequently, the illumination must be adapted accordingly.
    To adapt to the local conditions, for example, DE 20 2014 103 431 U1 describes a luminaire with an elongated housing and two lighting units rotatably mounted thereon. As a result, an adjustment of an angle at which light is emitted by the luminaire can be set and adapted to the local conditions. The
    Lighting units each have LEDs and a reflector in the form of a curved plate which extends over the entire length of the lighting unit. At the respective ends of this plate are obliquely outwards and downwards

    P42322-DE H4X e.U.
    inclined, flat plates provided. It is thereby achieved that the intensity of the emitted light steadily decreases in the direction of the longitudinal extension of the lamp, thereby avoiding hard transitions in the lighting.
    In order to present goods in an appealing way, emphasis is usually placed on lighting the goods as evenly as possible along the aisles. Furthermore, the aisles should be illuminated in a brightness that is pleasant for the customer. In order to illuminate longer aisles evenly, several or larger-sized lamps are usually the ones described above
    Kind of necessary.
    It is therefore an object of the present invention to provide a luminaire which has a compact structure with improved lighting properties, in particular with regard to the size of the area to be illuminated and / or with regard to the uniform illumination of a predetermined area to be illuminated and / or with respect to glare properties.
    This object is achieved by a lamp with the features of claim 1.
    According to the invention, a lamp is provided with a carrier device and at least one lamp device that extends in a longitudinal direction and is mounted on the carrier device. The lighting device has a carrier part extending in the longitudinal direction, a plurality of illuminant units which are arranged on a side wall of the carrier part, and a reflector device fastened to the carrier part. The reflector device has at least two spaced apart in the longitudinal direction

    H4X e.U
    Reflector sections which are each formed by reflector surfaces which are concavely curved in at least two directions of curvature. The at least two reflector sections are oriented towards the side wall of the carrier part. Furthermore, a lamp unit is assigned to one of the at least two reflector sections.
    According to the invention, a luminaire with a carrier device, which is provided for fastening to a ceiling of a building room, and at least one luminaire device is thus provided. The at least one lighting device is mounted or arranged on the carrier device and thus mechanically coupled to the at least one lighting device. The at least one lighting device has a support part or a support structure which extends in a longitudinal direction. The at least one lighting device serves to emit light and accordingly has a plurality of illuminant units which are arranged on the carrier part, in particular on a side wall of the carrier part which extends in the longitudinal direction. In the simplest case, the carrier part can thus be designed, for example, as an elongated plate. The at least one lighting device furthermore has a reflector device for reflecting the light which can be emitted by the lighting means units. The
    Reflector device has at least two spaced in the longitudinal direction
    Reflector sections or reflector regions, which are each formed by reflector surfaces that are concavely curved in at least two directions of curvature. The individual reflector sections are thus in each case open cavities which are separated from one another in relation to the longitudinal direction and which are separated by
    Reflection of light provided reflector surfaces are defined or limited. The at least two reflector sections are oriented toward the side wall of the carrier part, that is to say the respective reflector surfaces are the
    4/39
    4P42322-DE H4X e.U
    Side wall, on which the illuminant units are arranged, oriented facing. In this case, each reflector section is assigned at least one illuminant unit or is arranged opposite it on the side wall, so that light can be emitted onto the surface forming the respective reflector section and can be reflected by it for illuminating an illumination area. The curvature of the reflector surfaces is designed in such a way that the light that can be emitted by the illuminant units is reflected in a direction transverse to the longitudinal direction.
    This design of the lighting device, according to which several discrete
    If reflector sections are provided in a concave shape in at least two directions of curvature of curved surface areas, the reflector surface is enlarged in the longitudinal direction in relation to the length of the lighting device. With a given size of the reflector surface as a whole, the
    Length of the lighting device and thus the lamp advantageously reduced. Since one reflector section is also irradiated by one or more individual illuminant devices, a very high light output is achieved for each reflector section. In relation to the length of the luminaire, the light output is increased. Furthermore, the concave, multi-axis
    Curvature achieved a particularly uniform light distribution, particularly in relation to the longitudinal direction. The special curvature of the reflector sections means that two or more reflector sections can illuminate a larger area than with conventional luminaires of the same size. Furthermore, the curvature of the reflector sections and their separate arrangement prevent glare with respect to a viewing direction along the longitudinal direction in an improved manner.

    Advantageous refinements and developments result from the subclaims which refer back to the independent claims in conjunction with the description.
    According to one embodiment of the lamp, the number of
    Illuminant units correspond to the number of reflector sections and in each case one illuminant unit is arranged opposite and assigned to a respective reflector section. Exactly one illuminant unit is thus provided for each reflector section. This offers the advantage that a large lighting area can be illuminated with a minimal number of lamps. The space requirement of the lamp units is thus reduced, which promotes a compact structure of the lamp.
    According to a further embodiment it can be provided that on the
    A plurality of cooling chimneys which are arranged one behind the other in relation to the longitudinal direction and which extend in a vertical direction of the lighting device extending transversely to the longitudinal direction is formed on the side wall of the carrier part. The lamp device vertical direction extends in a ceiling-mounted state of the lamp at an angle of less than 90 degrees
    Direction of gravity. According to this embodiment, cooling chimneys, e.g. provided in the form of channels, each having two openings opposite in the vertical direction of the lighting device, which are connected by peripheral walls of the respective cooling chimney. The peripheral walls thus define the cross-sectional shape of the respective
    Cooling fireplace and extend between the opposite openings. Since the cooling chimneys are formed on the side wall of the carrier part, on which the lamp units are also arranged, one of the
    6/39
    -6P42322-DE H4X e.U.
    Circumferential walls formed by the side wall of the carrier part. Consequently, the heat dissipation from the illuminant unit is improved by cooling chimneys, since the chimney effect which arises as a result of the heating of the side wall, by the extension of the cooling chimneys in the vertical direction of the lighting device, ensures improved convection. Due to the improved cooling, the
    Performance of the illuminant units further increased and thus the number of illuminant units required to achieve a desired
    Illumination power are necessary to be reduced. As a result, the lamp can be made smaller and more compact.
    Optionally, the cooling chimneys can be formed in one piece with the side wall, for example by a casting process.
    Generally, the support member can be made of a metal material, e.g. one
    Aluminum alloy or aluminum. Due to the high thermal conductivity of metal materials, in particular aluminum alloys or aluminum, the heat dissipation of the luminaire is improved, so that the performance of the lighting device can be further increased.
    According to a further embodiment, it can be provided that the carrier part of the lighting device has a plurality of ribs which extend from the side wall of the carrier part at least in sections along a vertical direction of the lighting device extending transversely to the longitudinal direction.
    Accordingly, the carrier part has a plurality of ribs arranged on the side wall, which are arranged at a distance from one another with respect to the longitudinal direction. It can be provided that the ribs are in one piece
    7/39
    -Ί P42322-DE Η4Χ e.U are formed with the side wall of the support part or are attached to it, e.g. Material, form-fitting or non-positive. An extension, at least in sections, along the vertical direction of the lighting device can be realized, for example, by L-shaped or arc-shaped ribs. By direct
    Contacting the ribs with the side wall of the carrier part, the ribs are thermally coupled to the side wall. This increases the surface area of the carrier part and thus further improves the heat dissipation and cooling of the lamp units. In addition, the ribs advantageously provide a mounting surface, e.g. provided for fastening the reflector device, io.
    According to a further embodiment of the lamp, it can be provided that the reflector surfaces forming the at least two reflector sections and a first surface of the side wall of the carrier part on which the
    Illuminant units are arranged, together each delimit a respective light exit opening of the lamp. The respective reflector surface thus extends to the inner surface of the side wall of the carrier part, which is oriented towards the reflector device, or ends there. An intermediate reflector segment, which is in relation to the
    Extending longitudinally between two successive reflector sections is thus in contact with the inner surface or the first surface of the side wall of the carrier part. In this way, particularly good glare control is achieved when looking obliquely to or along the longitudinal direction, since the view of the luminous means is blocked.
    As an alternative to this, it can be provided that the at least one lighting device further has a cover strip, the cover strip on a first surface
    8/39
    P42322-DE H4X e.U, the side wall of the carrier part, on which the illuminant units are arranged, is arranged. In this case, an elongate bar, that is to say a bar extending along the longitudinal direction, is arranged on the inner surface of the side wall oriented toward the reflector device and thus projects from the inner surface. In particular, the cover strip is arranged between a lower end section and the respective lamp unit with respect to a lamp device width direction extending transversely to the lamp device vertical direction. The illuminant units are thus aligned with respect to a viewing direction along the
    Luminaire uprighting is shadowed by the bar, so that glare from the lamp units is prevented in an improved manner.
    According to a further development it can also be provided that the reflector surfaces forming the at least two reflector sections and the
    The cover strip together delimit a respective light outlet opening of the lamp. The respective reflector surface extends up to or ends at the cover strip. An intermediate reflector segment, which extends in relation to the longitudinal direction between two successive reflector sections, is thus in contact with the cover strip. This will be a particularly good one
    Glare achieved when looking obliquely to or along the longitudinal direction.
    According to a further embodiment of the lamp, the lamp units can each be designed in particular as LED lamp units. Accordingly, a lamp unit comprises one or more light-emitting diodes, LEDs for short. LEDs offer the advantage that high light intensities are achieved with a relatively low heat output.
    9/39
    -9P42322-EN
    H4X e.U
    The illuminant units can optionally be designed as chip-on-board LED units or as chip-scale packaging LED units. “COB is an abbreviation for the English term chip-on-board. COB LED units have a plurality of LED elements or LED chips that are on a
    Carrier substrate arranged and there electrically connected in parallel or in series and with a cover layer, e.g. a phosphor layer. COB-LED units have a high power density in relation to their space requirements, which facilitates a compact structure of the luminaire. Furthermore, COB-LED10 units offer the advantage that they have a homogeneous beam quality and a high color rendering index. Chip-scale packaging LED units, or CSPLED units for short, also have a high power density in relation to their space requirements.
    According to a further embodiment of the luminaire, it can be provided that the illuminant units are each designed for electrical current supply with an operating current between 300 milliamperes (mA) and 1050 mA. Particularly high light outputs of the illuminant units are achieved in this area. COB-LED units in particular can be used in this area
    Light outputs in the range of about 1850 lumens per LED unit can be achieved. As a result, a desired brightness can be achieved with just a few LED units, which further facilitates a compact design of the lamp.
    According to one embodiment, the at least one lighting device can be rotated on the pivot axis about a pivot axis extending along the longitudinal direction
    Carrier device can be stored. The lighting device is accordingly pivotable with respect to a pivot axis extending along the longitudinal direction.
    10/39
    -10P42322-DE H4X e.U.
    Consequently, the orientation of the lighting device and thus the direction of radiation of the light that can be emitted by means of the illuminant units via the reflector sections can be set. This advantageously increases the flexibility when attaching the lamp relative to one to be illuminated
    Area.
    According to a further embodiment, it can be provided that the carrier device has a longitudinal member extending in the longitudinal direction, a first cross member arranged on a first end section of the longitudinal member and extending transversely thereto, and a second cross member which is arranged on a second end section of the longitudinal member and extends across the side member. In this case, the at least one lighting device can be mounted, for example, on the cross members.
    As an alternative to this configuration of the carrier device, the carrier device can also be designed as a circumferential rectangular frame. Here, the carrier device thus has two longitudinal struts extending in the longitudinal direction and two transverse struts extending transversely thereto and connecting them. Optionally, one can continue on the carrier device towards the outside
    Struts protruding, all-round bar can be provided. The peripheral frame can advantageously be inserted into a mounting recess, which is provided, for example, on a ceiling of a building room. The optional bar is used for contact with the ceiling. Furthermore, a fastening device for fastening the frame to a ceiling can be provided on the carrier device. In particular, the fastening device can be designed as a bracket which is rotatably mounted on the carrier device and biased by means of a spring

    - 11P42322-DE H4X e.U.
    is. The bracket is particularly intended to reach behind an area of a ceiling of a building room.
    According to a further embodiment, the lamp can have a fixing device 5 for fixing the at least one lamp device in a pivoting position. The fixing device can be formed, for example, by a latching mechanism which latches the at least one lighting device with the carrier device in specific pivot positions and in this way fixes them.
    io
    According to one embodiment it can be provided that the lamp has a first lamp device and a second lamp device.
    In particular, it can be provided that the at least two reflector sections 15 of the first lighting device and the at least two reflector sections of the second lighting device are oriented in opposite directions. Accordingly, the first and the second lighting device are arranged on different sides of the central plane with respect to a central plane extending in the longitudinal direction and in the vertical direction, and the reflector surfaces are oriented away from the central plane.
    As an alternative to this, it can also be provided that the at least two reflector sections of the first lighting device and the at least two reflector sections of the second lighting device are oriented towards one another. According to this optional design, the first and second lighting devices are on different sides of the central plane
    12/39
    -12P42322-DE H4X e.U,
    Arranged center plane and the reflector surfaces are oriented towards the center plane
    These optional configurations of the lamp are especially for the
    Application in corridors extending between opposite areas to be illuminated is advantageous. Due to the construction described above with a first and a second lighting device, which emit light on opposite sides, the areas to be illuminated arranged on both sides of the aisle can be illuminated by a lighting device.
    Herein, "one-piece," one-piece, "integral or" components formed in one piece is generally understood to mean that these components are present as a single part that forms a material unit and in particular are produced as such, one of which is not without the other component

    a viewing direction of an upper side O of the luminaire 1. FIGS. 3 and 4 each show sectional views which result for different designs of the luminaire 1 in a section along the line A-A shown in FIG. 2.
    As shown in FIGS. 1 to 4, the lamp 1 has a carrier device 2 and at least one lamp device 3, 4. As can be seen in particular in FIG. 1, the luminaire 1 can in particular have a first lighting device 3 and a second lighting device 4. The first and the second lighting device 3, 4 can in particular be designed in the same way. The following
    Comments on a lighting device 3, 4 thus apply in a general manner to the first and second lighting devices 3, 4 and to possible further lighting devices of the lighting device 1.
    As shown in FIGS. 1 to 4, the lighting device 3, 4 comprises a carrier part
    30, 40, a reflector device 50, 60 and several illuminant devices
    5, wherein in FIGS. 3 and 4 a lighting device 5 is only shown symbolically.
    1 and 2 show an example of a lighting device 3, 4 with a support part 30, 40 extending in a longitudinal direction L3, L4. The support part 30, 40 has a side wall 31, 41 extending in the longitudinal direction L3, L4. Furthermore, the carrier part 30, 40 has a large number of optional cooling chimneys 32, 42 and a large number of optional ribs 33, 43.
    As can be seen in particular in FIGS. 3 and 4, the illuminant units 5 are arranged on the side wall 31, in particular on a first surface 31a of the side wall 31. In FIGS. 3 and 4, the illuminant units 5
    16/39
    -16P42322-DE H4X e.U.
    shown only symbolically. The illuminant units 5 can, for example, each be designed as LED illuminant units, in particular as chip-on-board LED units or as chip-scale packaging LED units.
    As can also be seen in particular in FIGS. 1 and 2, the plurality of optional cooling chimneys 32, 42 is arranged on the side wall 31, 41 of the carrier part 30, 40 and is arranged one behind the other in relation to the longitudinal direction L3, L4. The cooling chimneys 32, 42 each extend in a light device vertical direction H3, H4 running transversely to the longitudinal direction L3, L4. As especially in the
    3 and 4, the cooling chimneys 32, 42 form channels extending in the light device vertical direction H3, the side walls of which connect two openings 34A, 34B, 44A, 44B opposite in the light device vertical direction H3. As can be seen in particular in FIGS. 1 and 2, the cooling chimneys 32, 42 can be designed, for example, with a rectangular cross section. This can be realized, for example, in that webs 32A, 42A are provided on a second surface 31b of the side wall 31 which is oriented opposite to the first surface 31a and which project or protrude from the second surface 31b of the side wall 31 in order to form the cooling chimneys 32, 42 across to the
    Extend side wall 31. Furthermore, an outer plate 32B, 42B extending in the longitudinal direction L3, L4 is provided, which connects the webs 32A, 42A. The side wall 31, 41, the webs 32A, 42A and the plate 32B, 42B thus together define the cross section of the cooling chimneys 32, 42.
    By extending the cooling chimneys 32, 42 along the vertical direction H3, H4, the heat dissipation from the illuminant units 5 is improved. As a result, the performance of the illuminant units 5 can be increased
    17/39
    -17P42322-EN H4X e.U. Consequently, a high luminosity can be achieved with only a few, and therefore powerful, illuminant units 5. This reduces the space required on the side wall 31, 41 by the illuminant units 5, so that the extension of the side wall 31, 41 in the longitudinal direction
    L3, L4 can be reduced.
    As further shown in FIGS. 1 to 4, the optional ribs 33, 43 are spaced apart from one another with respect to the longitudinal direction L3, L4. The ribs 33, 43 extend from the side wall 31, 41 of the carrier part 30, 40. In particular, the ribs 33, 43 protrude from the first surface 31a of the side wall 31, as e.g. 3 and 4 is shown. The ribs 33 can be L-shaped or arc-shaped, for example, as is shown by way of example in FIGS. 2 to 4. Here, the ribs 33 have a first section 33A extending transversely to the side wall 31 and a second section 33B extending transversely to the first section 33A. The second section 33B runs in particular along the lamp device vertical direction H3 or along the side wall 31, 41 and is connected to the first section 33A, for example directly or indirectly via a curved third section 33C, as is shown by way of example in FIGS. 3 and 4 , In general, a rib 33, 43 thus extends at least in sections along a vertical direction of the lighting device H3, H4 running transversely to the longitudinal direction L3, L4.
    The reflector device 50, 60 is fastened to the carrier part 30, 40, for example on the optional ribs 33, 43 or on the side wall 31, 41. FIGS. 3 and 4 schematically show a on a rib 33 or on the reflector device 50, 60 molded mounting boss 35 shown. At this
    18/39
    -18P42322-DE H4X e.U.
    the reflector means 50, 60 and the rib 33 can be attached to each other, e.g. by gluing, screwing, locking or similar. As is shown in particular in FIG. 1, the reflector device 50, 60 has at least two reflector sections 51, which are spaced apart in the longitudinal direction L3, L4,
    61 on. 1 shows, by way of example, a reflector device 51, 61 which has a total of four reflector sections 51, 61. Of course, more than four reflector sections 51, 61 can also be provided. The reflector sections 51, 61 are each formed by reflector surfaces 51a, 61a which are concavely curved in at least two directions of curvature. As can be seen in FIG. 1, the reflector surfaces 51a, 61a forming the reflector sections 51, 61 each define a shell-shaped or spoon-shaped cavity. In this case, the reflector surfaces 51a, 61a are each curved in relation to the longitudinal direction L3, L4 and also in relation to the light device vertical direction H3, H4. 1 shows, by way of example, a mirror-symmetrical course of the reflector surface 51a, 61a with respect to a plane of symmetry extending in the vertical direction H3, H4 and perpendicular to the longitudinal direction L. The section line A-A shown in Fig. 1 lies in the plane of symmetry. Optionally, the reflector sections 51, 61 are each separated from one another with respect to the longitudinal direction L by intermediate sections 52, 62 extending in the longitudinal direction L. The intermediate sections 52, 62 follow the course of the edge contour of the respective reflector surface 51a, 61a.
    As shown in FIG. 1, in the event that the lamp 1 has a first and a second lamp device 3, 4, it can be provided that the at least two
    Reflector sections 51 of the first lighting device 3 and the at least two reflector sections 61 of the second lighting device 4 are oriented in opposite directions. In particular, they have the reflector sections 51

    1, 3 and 4, the at least two reflector sections 51, 61 of the side wall 31, 41 of the carrier part 30, 40, in particular the first surface 31a of the side wall 31, are oriented towards. In particular, a lamp unit 5 is in each case one of the at least two
    Associated reflector sections 51, 61. As can be seen in particular in FIGS. 3 and 4, light can be emitted from the illuminant units 5 onto the respective reflector surfaces 51a, 61a in this way and reflected by them, as symbolically illustrated by the arrow P in FIGS. 3 and 4 is.
    FIG. 10 schematically shows a light distribution that can be achieved by means of the lamp 1, which has two lamp devices 3, 4 with reflector devices 50, 60, which, as shown in FIG. 1, is designed with separate, concavely curved reflector sections 51, 61. Lines XI, X2 and X3 shown in FIG. 10 each represent lines of the same brightness, the brightness decreasing from line XI via line X2 to line X3. In the present example, line X3 delimits an illuminated area B. As can be clearly seen in FIG. 10, the maximum extension 1-B of the illuminated area B is approximately 30 times as long as the length II of the lamp 1 in relation to the longitudinal direction L3, L4. Due to the design of the reflector device 50, 60, a small number can be used

    Illuminant units 5 achieved a very compact construction of the lamp L in relation to the illuminated area B.
    As can be seen in particular from FIG. 1, the described design of the reflector device 50, 60 with separate, concavely curved reflector sections 51, 61 furthermore dazzles an observer who along the longitudinal direction L3, L4 onto the lower side U of the lamp 1 looks, reliably prevented.
    Optionally, the number of illuminant units 5 can correspond to the number of reflector sections 51, 61. In this case, a lamp unit 5 is arranged opposite and assigned to a respective reflector section 51, 61. This is shown schematically in FIG. 11, FIG. 11 being a top view of the second surface 31b, 41b of FIG
    Side wall 31, 41 of the carrier part 30, 40 shows.
    As shown by way of example in FIGS. 1 and 3, the at least one lighting device 3, 4 can furthermore have a cover strip 6. The cover strip 6 is in relation to the light device vertical direction H3 between one to the lower
    Side U directed lower end of the side wall 31, 41 and the
    The illuminant unit 5 is arranged and projects from the first surface 31a of the side wall 31, as shown in FIG. 3. As a result, when looking in the light device vertical direction H3, H4
    Illuminant units 5 covered by the cover strip 6 and thus more reliably prevents glare to a viewer who is looking at the lower side U of the lamp. Here, the reflector surface 51a, 61a forming the respective reflector section 51, 61 and the cover strip 6 together limit each

As shown in FIG. 4, the reflector surface 51a extends up to the first surface 31a of the side wall 31. The intermediate section 52, which cannot be seen in FIG. 4, since it is located behind the reflector surface 51a in relation to the longitudinal direction L3, lies in particular against the surface 31a of the side wall 31. Thus, the reflector surface 51a, when viewed along the longitudinal direction L3, covers the lamp unit 5 following in relation to the longitudinal direction L3. This further improves glare protection for a viewer who walks along the
    Longitudinal direction L3, L4 looks at the lower side U of the lamp 1.
