Definitions

  • the invention relates to a luminaire according to the preamble of claim 1.
  • Such a light is off DE 299 01 397 U known.
  • a luminaire of conventional design has a housing that a ceiling wall and at least two of the ceiling wall, for. has opposing downwardly extending side walls. As a rule, two further side walls are provided, which are connected to the first side walls and stabilize the housing. In this known construction, at least the top wall and the side walls are required. This leads because of the required number of components or component sections to a considerable effort in terms of size, weight, cost of materials, manufacturing and assembly or pre-assembly.
  • the invention has for its object to simplify a lamp of the type specified. This applies in particular with regard to a reduction of the components or component sections.
  • the housing is formed by two elongate side parts, each having an upper and a lower longitudinal edge, wherein the upper longitudinal edges are partially interconnected, and wherein the lower longitudinal edges are spaced apart and define a lower light exit opening.
  • a lamp according to the invention is of a smaller size, because at least in the region of at least one longitudinal section in which the upper longitudinal edges are connected in sections, the lamp or the housing has a smaller width. It is thus not only reduces the space, but also the cost of materials.
  • a ceiling wall omitted, which also leads to a reduction in space, weight and material cost.
  • Another advantage of the embodiment of the invention is that the side parts are uneven or not parallel to each other, e.g. roof-shaped or can be arranged, which leads to a greater stability compared to a conventional box shape.
  • a lower light exit opening is created over which a sufficiently large housing space can be realized, in which a reflector, connecting means for at least one associated lamp and holding means for the reflector and the connection means can be arranged.
  • the connection of the side parts is preferably done by gluing. It is advantageous to form mutually parallel adhesive surfaces to achieve a planar and stable connection.
  • the side parts can be easily formed by plates which are flat or deformed transversely to their plane in order to obtain the partial connection at the upper longitudinal edges.
  • the upper longitudinal edges may lie directly against each other or they may be at a distance from each other, in the holding means, e.g. arranged for the reflector and / or the connection means and / or support members for attaching or suspending the lamp and preferably can be connected simultaneously with the side panels.
  • the invention is particularly well suited for an elongated and straight extending luminaire, which requires greater stability, which is due to the length.
  • the longitudinal edges can be at a distance from one another, whereby an upper housing opening is formed, which is advantageous for various reasons.
  • an interior enlargement is thereby created, which extends only over a partial region of the housing.
  • the upper housing opening can also be exploited to arrange an operating device or other components of the lamp in their area in the housing.
  • an inner housing with an example U-shaped Cross-sectional shape to be arranged below the upper housing opening in the housing, which not only leads to a stabilization of the housing or the holding means, but in which the operating device can be alternatively arranged protected.
  • the above-described upper housing opening can also form an upper light exit opening. As a result, an indirect lighting can be realized.
  • the side panels are preferably made of wood or Eternit. Side parts made of these materials are not only suitable because of the existing construction, but they also characterize a special design of the lamp.
  • the light exit opening of a luminaire is replaced by, e.g. bounded opposite housing walls.
  • it is endeavor to form the edge surrounding the light emission opening as narrow as possible in order to achieve not only a small construction but also an acceptable appearance of the luminaire.
  • the stability of the side walls is relatively low, especially when the edges surrounding the light exit opening are to be kept narrow.
  • the invention is based on the further object to stabilize a lamp specified in the preamble of claim 14 way.
  • the light influencing means are connectable to the lower edge regions of at least two housing walls such that the light influencing means form a housing strut acting parallel to the light exit opening and acting inwards and / or outwards transversely to the housing walls.
  • housing walls are connected to one another and stabilized by the light influencing means.
  • These housing walls are preferably housing walls which lie opposite one another, wherein the embodiment according to the invention is particularly suitable for elongated housing walls which are relatively unstable by nature.
  • This stabilization occurs without a significant increase in the expense of material and / or construction.
  • the housing strut can be formed in a simple construction by arranged between the light influencing means and the housing walls pin connections. In this case, it is particularly advantageous to design the housing strut or the journal connections in such a way that they arrive simultaneously in their operative connection when the light-influencing means are inserted, so that a special joining of the strut components or journal connection components is eliminated.
  • a simple and easy to handle installation of the light influencing means and preferably also the bracing is achieved when the light influencing means are connected by a latching device with the housing.
  • an adhesive bond therefore represents an uncertainty factor, since it can not be ruled out that after loosening the adhesive bond, at least part of the luminaire can fall down and cause damage to people or objects , This disadvantage is especially true for a lamp that is suitable for cultivation, z. B. on a wall or a ceiling, or is set up for hanging.
  • the invention is therefore based on the further object of simplifying and / or rationalizing the connection of at least two connecting parts in a luminaire described in the preamble of claim 27 and to improve the security against falling of at least one connecting part.
  • the two connecting parts are connected to one another directly or indirectly by gluing and connected to each other by an additional securing device. This ensures that even after an unwanted release of the adhesive bond, the dissolved connection part does not fall.
  • a form-locking effective security device is particularly well, in particular such a security device whose effectiveness is based on a mutual entanglement of the connecting parts.
  • a hooking device is not only easy and inexpensive to produce but also assembles and brings into the hooking position.
  • a hooking device can be handled easily and disassembled quickly.
  • a prescribed adhesive bond and / or securing device for bonding and / or securing of two side walls of the housing of the lamp are used, which are glued directly to each other or indirectly glued together in the presence of an intermediate part.

Falling is prevented by the fact that the other connecting part is connected by the securing device 51 directly or indirectly to the housing 2 or an attachment of the same and therefore hold the unintentionally released connection part and can secure against falling.
  • the securing device 51 is preferably positively acting, that is, it has on the falling-vulnerable part on a securing element 51a, which engages over a securing element 51b of the securing device, preferably so hooked over and behind that a lateral slipping is prevented.
  • the corresponding securing element 51b may be attached directly or indirectly to the housing 2, for. B. on a in the cavity 15 of the housing 2 arranged attachment which is disposed in the upper region of the cavity 15 and may be a supporting part of the connection elements 16 for the light source.
  • the securing device 51 in which the securing device 51 is arranged laterally with respect to the vertical longitudinal center plane E of the luminaire 1, it is advantageous for improving safety to provide a securing device 51 on both sides of the longitudinal median plane E, the securing devices 51 preferably being arranged and formed in mirror image can.
  • the securing device 51 serves to secure a connection part glued on the inside to the housing wall 2a for connecting the light-influencing element, wherein the securing device 51 is arranged on one side in the cavity 15 of the housing and opposite a mirrored arranged and formed securing device 51 is provided.
  • the following description of the lamp 1 or securing device 51 according to the embodiment according to Fig. 9 is therefore limited to one side of the lamp 1. On the opposite side, the lamp 1 is at least in mirror image with respect to the securing device 51.
  • the securing element 51a is arranged on the intermediate piece 37 or on the profile rail 37a, preferably integrally formed thereon. It may be formed by a, preferably tapered, securing arm 51c projecting upwards from the upper end of the intermediate piece 37 and which may extend over the entire horizontal length of the intermediate piece 37. But it may also be a rod-shaped safety arm 51c, which protrudes in the middle length region of the intermediate piece 37 upwards, or it may be several z. B. two horizontal spaced from each other having rod-shaped Securing arms 51c may be provided. The safety arm 51c is bent or angled inwardly at its upper free end, preferably hook-shaped, so that the free end of the hook points downwards.
  • the securing element 51b is formed by the reflector 17 or arranged on this and formed in the embodiment by a lateral extension 17a, which preferably has an upwardly directed leg 17b, which is overridden by the hook shape of the securing arm 51c from the outside and behind.
  • the reflector 17 may be formed integrally with the securing element 51b, which may be a bent part or an extruded part.
  • the hooking device 51 forming the hooking device is preferably formed so that when mounting the securing device 51, the form-fitting cross-locking elements 51a, 51b pass through the assembly movement in their Verhakungsposition. There are therefore no special assembly movements required.
  • the reflector 17 in which the intermediate pieces 17 are adhesively bonded to the housing walls 2a and the side parts 11, the reflector 17 is moved through the housing opening into the cavity 15 into its fastening or screwing position. In this case, the lateral extensions 17a or leg 17b automatically reach under the securing elements 51a, in particular in their hook shape. In an unwanted solution of one or both spacers 37 remain this due to the attack on the reflector 17 in its suspended holding position in which they are secured and the light influencing means 4 and the grid 31 hold.
