Definitions

  • the present invention relates to a luminaire, in particular for a light band.
  • a light band for example, a band-like sequence of individual, usually rectilinear lights referred to.
  • a light band for example. Have a length of more than 3 meters.
  • the wiring for the supply of light sources of the individual lights can be provided.
  • a luminaire for such a light band which can also be referred to as a continuous line luminaire, usually has a supporting profile extending in a longitudinal direction, which can be mounted on a wall or ceiling.
  • a device carrier On the support section, a device carrier is attached to which in turn a light source is mounted.
  • a tubular lamp then emits light radially from the lamp.
  • fluorescent tubes or other tubular bulbs are used.
  • such a luminaire can usually have a reflector attached to the device carrier, which reflector reflects the light impinging on it in a well-defined manner.
  • the light emitted by the light source in particular substantially uniformly radially, can be deflected by reflection into a specific spatial area, so that this area is particularly well illuminated, while other spatial areas are "dimmed" by means of the reflector.
  • Such a reflector is particularly suitable when the light band is used in the manner of a ceiling lighting for a room, wherein in a mounted state of the light band of the light emitted by the illuminant upward proportion of the light generated by this reflected by the reflector and thus is radiated down substantially again, so that the spatial area below the acting as a ceiling lighting light is effectively and completely illuminated.
  • An improved illumination by means of a luminaire can be achieved by providing a diffuser, by means of which a so-called longitudinal glare-shielding of the light emitted by the luminous means in a main emission direction can be ensured.
  • a problem in this case is often an optimal spatial arrangement of the diffuser in the luminaire, in particular relative to the reflector and to the light source, in connection with a precise and mechanically stable attachment of the diffuser to the reflector.
  • a relatively close arrangement of the diffuser and the reflector relative to one another and also relative to the luminous means of the luminaire can cause a disturbing heat development in this region to occur due to the relatively small gap between these components, which in turn results in an undesirable reduction of the service life or more of the components of the luminaire may result.
  • the US 4,338,653 A discloses a lamp with a device carrier attached to a support profile.
  • a light source and a reflector are mounted on the equipment carrier.
  • the latter has, in a reflector cross-sectional profile, a base wall and two side walls projecting from the base wall.
  • the reflector is attached to the sidewalls of the diffuser.
  • the DE 9 320 823 U1 discloses a luminaire comprising a support profile with a device carrier to which a lamp and a reflector are attached.
  • the DE 9 307 685 U1 discloses a ceiling light with a diffuser, which can be releasably secured to the reflector by means of a fastener.
  • the EP 1 584 860 A2 discloses a luminaire with a housing, a lighting means 12 and two interpretable as a diffuser prism discs and a reflector.
  • the WO 2007/088036 A2 describes a lamp with a box-shaped luminaire housing and a light exit element, which can be understood as a diffuser.
  • the invention is based on the general idea of arranging the diffuser, with respect to its cross-sectional profile, at a distance from the reflector and at least partially on a side of an exit plane of the reflector which is remote from the illuminant, relative to an exit plane of the reflector.
  • the exit plane of the reflector is defined by the two side walls of the reflector cross-sectional profile, which each have a distal end with respect to the illuminant.
  • the parallel to the longitudinal direction of the lamp extending exit plane of the reflector is defined in the reflector cross-sectional profile by connecting the straight line connecting the two distal ends of the side walls.
  • the light emitted by the light can be radiated into a half space defined by the reflector opening of the reflector.
  • Another significant advantage of the arrangement geometry of the diffuser according to the invention relative to the reflector is that heat generated by the light bulb does not accumulate in a relatively small volume within the reflector, but can be distributed throughout the reflector within the reflector. In this way, an undesirable reduction of the maximum life of individual components of the lamp due to overheating by the heat generated by the lamp can be largely avoided.
  • the diffuser arranged at a distance from the reflector is fastened detachably to the base wall of the reflector by means of at least one fastening element. In this way, a mechanically stable attachment of the diffuser is ensured at the reflector.
  • a width of the diffuser measured transversely to the longitudinal direction of the diffuser can be less than 50%, preferably less than 30%, a length of the exit plane of the reflector defining connecting line, which lies in a direction perpendicular to the longitudinal direction of the lamp cross-sectional plane. This ensures that a discharge of heat generated within the reflector due to a large spatial formation of the diffuser, especially in the region of the exit plane, is not undesirably prevented.
  • the cross-sectional profile of the diffuser can be arranged centrally on the connection line defining the exit plane of the reflector. This allows a particularly effective dissipation of waste heat generated within the reflector.
  • the respective fastening element may be formed as a clamp-like spring element which engages over the light-emitting means contactlessly on two opposite sides.
  • the formation as a clamp-like spring element allows an arrangement relative to the diffuser and the reflector (and at the same time also relative to the lighting means) by means of the fastening element in the manner of a "floating arrangement", i. for an observer, who can only see the fastener on closer inspection of the luminaire, the impression arises that the diffuser seems to "float" virtually free in the room.
  • the fastener in the manner of a clip this can be attached to both the reflector and the diffuser in a simple, but still very flexible manner.
  • the fastening element according to the invention allows a tool-free installation of the diffuser on the reflector, which is particularly advantageous if the lamp is to be mounted in a poorly accessible place, for example on the ceiling of a room or the like.
  • the fastening mechanism of the fastening element can be kept relatively simple both on the diffuser and the reflector, without thereby affecting its mechanical stability.
  • a technically particularly complex and therefore expensive in terms of its manufacturing attachment mechanism is in this way about liquid.
  • the fastening element acts in an attached to the diffuser and the reflector state as axial securing the diffuser relative to the reflector. This allows a fixation of the fastener on the reflector and the diffuser, such that unwanted free axial movements are largely suppressed to the fastener.
  • the fastener is a wire-formed part made of a single wire. This allows a very cost-effective production of the fastener.
  • a shaped wire part in terms of its geometric design, but also in terms of its spatial dimensions in a simple manner can be adapted very flexibly to different lights and related to different configurations of lighting, reflector and diffuser.
  • a wire-formed part produced from such a wire automatically has the spring-elastic properties required for a spring element if a suitable, spring-elastic wire material is selected for the shaped wire part becomes.
  • a suitable, spring-elastic wire material is selected for the shaped wire part becomes.
  • the diffuser can be designed as a straight-line profile rail.
  • the profile rail may then have a diffuser cross-sectional profile with a diffuser base portion extending in the longitudinal direction and two diffuser legs laterally projecting from the diffuser base portion.
  • the training as a profile rail is particularly useful when the lamp is to extend in practical use in an axial direction over a greater spatial distance.
  • several luminaires can then be arranged without problems in the axial direction to form a light band.
  • each of the two diffuser limbs in the diffuser cross-sectional profile has a diffuser holding section projecting inwards towards the diffuser base section, in each case in an edge region facing away from the base section.
  • two recesses arranged so as to be spaced apart from one another in the longitudinal direction may be provided on the respective diffuser holding section for releasably fastening the fastening element.
  • the fastening element can each have two diffuser-side fastening straps that are complementary to the diffuser holding sections of the diffuser element.
  • the two diffuser-side mounting bracket may be biased against the retaining portions of the diffuser leg in a fastened to the diffuser state of the fastener. This can be realized by means of a suitable geometric design of the two diffuser-side mounting bracket, preferably when the fastener is a wire-forming part, so that it can act as a spring element.
  • the fastener may have two reflector-side mounting bracket, by means of which the fastener can be releasably secured to the reflector.
  • the base wall of the reflector may have two complementary to the reflector-side mounting brackets recesses that can at least partially accommodate the reflector-side mounting bracket.
  • the two Reflector-side mounting bracket in a particularly preferred embodiment in a recorded in the recesses of the base wall state against the base wall of the reflector to be biased.
  • the reflector or the device carrier to be performed can, in order to allow easy accessibility to these components of the lamp for a worker, the respective fastening element on one of the two reflector-side mounting bracket from the corresponding recess of the base wall of the reflector be suspended and about the other mounted on the reflector reflector-side mounting bracket to be pivotable about a parallel to the longitudinal direction of the lamp pivot axis. Then, the diffuser, in particular for an exchange of the luminous means, can be pivoted about the pivot axis defined by the at least one reflector-side mounting bracket suspended from the reflector.
  • the two diffuser-side and / or reflector-side mounting bracket may each be integrally formed on the fastener.
  • each of the two reflector-side bracket can be connected in each case via an outer leg with a corresponding diffuser-side mounting bracket, wherein the two diffuser-side mounting bracket are connected to each other via an inner leg.
  • the diffuser can be secured by means of the fastening element in a simple manner against undesired axial movement relative to the reflector.
  • the fastener thus simultaneously assumes the task of axial securing the diffuser.
  • the diffuser due to its releasable attachment to the reflector by means of the fastener can be easily removed again from the reflector, which, for example, may be required if a defective bulb to be replaced.
  • a worker can thus easily access the mounted on the equipment carrier lamps and replace it if necessary.
  • This easy accessibility is generally also for to the light, in particular on the light source or the equipment carrier to be performed maintenance or cleaning work beneficial.
  • the two diffuser legs and / or the diffuser base of the diffuser can each have a prism structure on a side facing away from the luminous means.
