Definitions
- Luminaire with a housing with two side parts
- the invention relates to a lamp according to the preamble of claim 1 or 14 or 27.
- a luminaire of conventional design has a housing that a ceiling wall and at least two from the ceiling wall e.g. 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. Because of the required number of components or component sections, this leads to considerable expenditure in terms of size, weight, material expenditure, manufacture and assembly or pre-assembly.
- the invention has for its object to simplify a lamp of the type specified. This applies in particular to a reduction in the number of components or component sections.
- the housing is formed by two elongated side parts, each with an upper and a lower longitudinal edge, the upper longitudinal edges being connected to one another in sections, and the lower longitudinal edges being spaced apart and delimiting a lower light outlet opening.
- a lamp according to the invention is of a smaller size because, at least in the region of the at least one longitudinal section in which the upper longitudinal edges are connected to one another in sections, the lamp or the housing has a smaller width. This not only reduces the installation space, but also the material expenditure.
- a ceiling wall can also be omitted in the area of the at least one longitudinal section in which the upper longitudinal edges are connected to one another in sections, which likewise leads to a reduction in the installation space, the weight and the material expenditure.
- Another advantage of the configuration according to the invention is that the side parts are uneven or not parallel to one another, e.g. can be roof-shaped or arranged, which leads to greater stability compared to a conventional box shape.
- a lower light outlet opening is created with the advantages described above, through which a sufficiently large housing space can be realized, in which a reflector, connection means for at least one associated lamp and holding means for the reflector and the connection means can be arranged.
- the side parts are preferably connected by gluing. It is advantageous to form adhesive surfaces that run parallel to one another in order to achieve a flat and stable connection.
- the side parts can be formed in a simple manner by plates which are flat or deformed transversely to their plane in order to maintain the section connection at the upper longitudinal edges.
- the upper longitudinal edges can lie directly against one another or they can be spaced from one another in which holding means, e.g. arranged for the reflector and / or the connecting means and / or support parts for attaching or hanging the lamp and can preferably be connected to the side parts at the same time.
- the invention is particularly well suited for an elongated and straight-extending lamp in which a greater stability is required, which is due to the length.
- the longitudinal edges can be spaced apart, as a result of which an upper housing opening is formed, which is advantageous for various reasons. On the one hand, this creates an interior enlargement that only extends over a partial area of the housing.
- the upper housing opening can also be used to arrange an operating device or other components of the lamp in their area in the housing. It is also possible to have an inner housing with an eg U-shaped one To arrange cross-sectional shape below the upper housing opening in the housing, which not only leads to a stabilization of the housing or the holding means, but also in which the operating device can alternatively be protected.
- the above-described upper housing opening can also form an upper light exit opening. This also allows indirect lighting to be implemented.
- the side parts are preferably made of wood or eternit. Side parts made of these materials are not only suitable due to the existing construction, but also characterize a special design of the luminaire.
- the light exit opening of a luminaire is e.g. opposite, limited housing walls.
- the aim is to make 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 lamp.
- the stability of the side walls is relatively low, in particular if the edges surrounding the light exit opening are to be kept narrow.
- the invention is further based on the object of stabilizing a lamp of the type specified in the preamble of claim 14.
- the light influencing means can be connected to the lower edge regions of at least two housing walls in such a way that the light influencing means form a housing strut which acts parallel to the light exit opening and is effective transversely to the housing walls inwards and / or outwards.
- housing walls are connected to one another and stabilized by the light influencing means.
- These housing walls are preferably opposing housing walls, the configuration according to the invention being particularly suitable for elongated housing walls which are inherently relatively unstable. This stabilization takes place without a significant increase in the amount of material and / or the construction.
- the housing strut can be formed in a simple construction by means of pin connections arranged between the light influencing means and the housing walls. It is particularly advantageous to design the housing strut or the spigot connections so that when the light influencing means are inserted they are simultaneously in their operative connection, so that a special joining of the strut components or spigot connection components is not required.
- a simple and easy-to-use assembly of the light influencing means and preferably also the strut is achieved when the light influencing means can be connected to the housing by means of a latching device.
- the invention is therefore further based on the object of simplifying and / or rationalizing the connection of at least two connecting parts in a luminaire of the type described in the preamble of claim 27 and of improving the security against falling of at least one connecting part.
- the two connecting parts are directly or indirectly connected to one another by gluing and are connected to one another by an additional securing device. This ensures that the loosened connecting part does not fall off even after an unwanted loosening of the adhesive connection.
- a form-locking securing device is particularly well suited, in particular such a securing device, the effectiveness of which is based on mutual interlocking of the connecting parts.
- a hooking device can not only be produced simply and inexpensively, but also assembled and brought into the hooking position.
- a hooking device can be dismantled quickly and easily.
- a previously described adhesive connection and / or securing device can be used for the adhesive bonding and / or securing of two side walls of the housing of the lamp, which are bonded directly to one another or are indirectly bonded to one another if an intermediate part is present.
- the safety device according to the invention can also be arranged between other connecting parts of the lamp, for. B. between the housing or a side wall of the housing and attached to it by the adhesive connection intermediate pieces or rails, which carry connecting elements or latching elements, which are parts of a connecting device or latching device for connecting or latching a light influencing element of the lamp.

The securing arm 51c is bent or angled inward at its upper free end, preferably hook-shaped, so that the free end of the hook points downward.
- the securing element 51b is formed by or arranged on the reflector 17 and, in the exemplary embodiment, is formed by a lateral extension 17a, which preferably has an upwardly directed leg 17b which is overlapped and gripped from behind by the hook shape of the securing arm 51c.
- the reflector 17 can also be integrally formed with the securing element 51b, which can be a bent part or an extruded part.
- the interlocking device forming the securing device 51 is preferably formed such that when the securing device 51 is assembled, the interlocking overlapping securing elements 51a, 51b come into their interlocking position by the assembly movement. There are therefore no special assembly movements required.
- the reflector 17 is moved through the housing opening into the cavity 15 into its fastening or screwing position.
- the lateral extensions 17a or legs 17b automatically come under the securing elements 51a, in particular in their hook shape. In the event of an unwanted solution of one or both intermediate pieces 37, these remain in their suspended holding position, in which they are secured and hold the light influencing means 4 or the grid 31, due to the overlapping on the reflector 17.
