1 has a luminaire housing 1, a luminaire louvre 3 with end lamella 3 ₁ at each end and further lamellae 3 _j lying between the end lamella 3 ₁ , which are connected to one another, and lateral reflector walls 5 on both sides of a lamp ( not shown), which extends between two lamp sockets 7 on the two end faces of the housing 1. The luminaire grid 3 and the reflector walls 5 form a unit and are attached to the two end faces of the housing 1 via the respective end lamella 3 ₁ and a fastening element 11 on the housing 1 in a manner which will be explained below.

The fastening element 11 is shown in detail in FIGS. 4 and 5. It forms a one-piece Component with various connecting devices for connecting to the lamp holders 7 and the luminaire grid 3. These connections are at different points the fastening element is provided in a predetermined spatial relationship, so that when assembling the correct orientation of the various components to each other.

According to a preferred embodiment, the fastening element 11 is made of plastic, in particular from a thermoplastic, such as. B. PC, PP or SAN. UV resistant and refractory materials are preferred to prevent the fastener from being 11 becomes brittle prematurely. The fastening element 11 has a bottom wall 13, a rear wall 15 adjoining this essentially perpendicularly, and transverse walls 16, which extend perpendicular to the rear wall 15 and the bottom wall 13, so that a room area is determined, which in use (see. Fig. 2 and 3) in the direction is open at the bottom and in the direction of the opposite end face of the housing 1. The transverse walls 16 have holes 17 for the lead-through.

The bottom wall 13 lies against the housing bottom 18 in use. On the of the cross walls 16 and the rear wall 15 facing away are locking lugs 19 for connecting to the Housing bottom 18 provided. The locking lugs 19 have locking heads in a known manner, below which a groove is formed, into which the edges of an opening in the housing base 18 intervene. This opening is expediently with a widened section, through which the locking heads can pass, and a tapered section is formed, through which the locking heads cannot pass, the locking lugs 19 in inserted the widened section and then shifted to the tapered section are so that the locking heads hold the fastener 11 on the housing base 18. The locking heads can also be elastic and when attaching the fastener 11 can be pressed through holes in the housing with a slightly smaller diameter. According to yet another embodiment, the locking lugs can also be made of a relative hard plastic material and a head whose diameter is approximately that Corresponds to the diameter of corresponding holes in the housing and one below of the head arranged stem with a rectangular cross-section, the larger Length of this rectangular cross-section correspond to the diameter of the head and the smaller length of this cross section can be smaller than this diameter, so that below a head edge is created. The locking lugs are on the fastener 11 attached at a distance which is smaller than the distance of the corresponding Openings in the housing base 18. When inserting the locking lugs in these holes a deformation of these locking lugs and / or the housing plate in which the holes are formed are, and the housing plate snaps below the head in the area of a long Side of the stem. The deformation when the locking lugs are pressed in makes them secure kept in the locked state.

The rear wall 15 is adjoined by two on the side facing away from the bottom wall 13 with respect to the rear wall 15 to the front, that is to say angled towards the free end of the transverse walls 16, spaced apart wall sections 20a, 20b, each on a lateral End of the fastener. A spacer is attached to these wall sections 21 on, which is angled to the rear, ie away from the free end of the transverse walls 16 is. The spacer 21 extends rearward beyond the rear wall 15 and goes into a stop 23 at its end facing away from the wall sections 20a, 20b above, which, as can be seen from FIG. 2, bears against an end wall 25 of the housing in use. In the transition area between the wall sections 20a and 20b and the spacer As is best seen in FIG. 5, 21 is in each case a more angled forward Locking projection 26a or 26b, which, as will be described in more detail below, as Attack surface for a detent spring for attaching the lamp grid 3 is used.

From the rear wall 15 there is a frame carrier in the middle between the wall sections 20a and 20b 30 vertically in the form of a wall section cut out on three sides above or possibly also obliquely forward, of the two insertion holes 32 for inserting one Lamp holder 7 has. The insertion holes 32 can with locking devices, bayonet devices or the like for securing the lamp holders in a known manner be provided. The frame carrier 30 is elastically resilient, so that it from its in 4 and 5 shown rest position, to the rear, that is, from the free end of the transverse walls 16th away, can be shifted against an elastic force.

In the spacer 21 is a more recessed in the middle in the region of the frame carrier 30 Section 34 formed, the inclined surfaces 36 in the to the wall sections 20a, 20b adjoining lateral sections 38a and 38b of the spacer 21 passes over, so that an additional free space is created that the handling of the lamp relieved when inserting into the sockets.

To mount the lamp grid 3 on the fastening element 11, a detent spring 40 is fastened to the end lamella 3 ₁ of the lamp grid 3 at each end (cf. FIG. 2). This detent spring 40 has a zigzag shape and has an angled section 42, which serves as a detent head, and a sliding surface 44 adjoining this angled section 42.

To mount the lamp, a fastening element is placed in the housing 1 on the two end faces 11 fastened in that the locking lugs 19 through corresponding openings of the housing base 18 (not shown), which can be configured, for example, in the form of a pear, inserted and then locked in the longitudinal direction of the lamp, being in the locked Position of the stop 23 abuts the respective housing end wall 25, so that the Spacer 21, the rear wall 15 at a predetermined distance from the housing end wall 25 holds. The resulting space between the fastener 11 and the end wall 25 can in a corresponding embodiment for attaching electrical Components, such as ballasts, and used for cable routing become.

For further assembly of the lamp is in the two insertion holes 32 of the fastener 11 a lamp socket 7 on each of the two end faces of the housing 1 plugged in. The sockets 7 are through lines that pass through the line bushings 17 are guided in the transverse walls 16, connected. By performing through the cable bushings 17 eliminate the need for a separate cable holder, or the tying of the lines in this area. Then it is in the versions a lamp is inserted into the two ends of the housing.

The rest position of the frame carrier 30 on the two end faces of the housing 1 is determined that the distance between the lamp sockets for all expected housing tolerances is less than or equal to a minimum length of the lamp, given the type-related or manufacturing-related fluctuations in the length of the lamp is to be expected. With lamps, whose length is greater than this minimum length due to type or production, or in the case that said distance, e.g. B. due to the housing, is smaller than this minimum length, when inserting the lamp in the sockets 7, the holder 30 from its rest position deflected and pressed towards the respective end wall 25, so that dimensional tolerances be balanced and the lamp is held securely in the lamp housing.

After the lamp has been inserted, the luminaire grid 3 with the grid lamellae 3 _i , 3 _j and the reflector walls 5 connected to them is inserted into the housing 1 from below via the housing opening. As can be seen in FIGS. 2 and 3, the two reflector walls 5 are not connected to one another at their upper end, so that an opening remains between them. The reflector walls 5 can therefore be pushed over the lamp so that it comes to rest in the area between the reflector walls 5 and above the grid 3.

For insertion into the housing 1, the luminaire grid 3 is inserted from below through the housing opening until the upper edge of the end lamella 3 ₁ abuts the lower edge 45 of the transverse walls 16. The detent springs 40 slide over the respective projections 26a and 26b at the two lateral ends of the fastening element 11, the distance of the fastening elements 11 attached to the two end faces of the housing from the respective housing end wall 25, which is determined by the spacer 21 is set up so that the spring 40 is deflected from its rest position, engages with the angled section 42 over the projection 26a or 26b and thereby holds the grid 3 on the fastening element. The spring 40 is also designed so that it pulls the grid 3 upward, so that the upper edge of the end lamella 3 _{1 is held} largely free of play on the lower edges 45 of the transverse walls 16 and, as a rule, abuts the lower edges 45.

The lamp is now fully assembled. From the above description it can be seen that this assembly can be done without tools. Since the fastener 11 from a insulating plastic, there is a voltage spread between the socket and the case bottom prevented. For example, the insulating bottom wall prevents 13 an electrical contact of a lead wire that has come loose from the socket with the housing base 18.

The exemplary embodiment described above can be modified in various respects become. For example, the grid lamellae on the one hand and the reflective ones Sidewalls on the other hand form separate components, each separately with the invention Fastener via snap connections, similar to those previously for the attachment of the luminaire grid have been described, can be connected. The Fastening elements according to the invention do not necessarily have to be on the housing base attached or supported on the front side, but can e.g. B. also on a side wall the housing attached and / or supported. While previously a single lamp Luminaire has been described, a multi-lamp light can also be realized according to the invention are, separate fastening elements are provided for each lamp can be or a single fastener for attaching multiple lamps can be provided. Expediently, one gets its own elastic for each lamp provide resilient holder. Likewise, of course, also with wider lights a plurality of grids arranged side by side with correspondingly modified grids according to the invention Fasteners are attached in a lamp housing.

Those disclosed in the foregoing description, drawings and claims Features of the invention can be used both individually and in any combination Realization of the invention in its various embodiments may be essential.
