    LAMP WITH LATERAL SPRING SYSTEM FOR FASTENING A COVER
    DESCRIPTION
    The present invention relates to a lamp with a plurality of spring elements which are set up to hold a cover in one side of a support structure of the lamp.
    The mounting of a cover on a light exit opening of the lamp is solved in the prior art by various measures. One possibility is to attach the cover to a lamp housing using spring elements. This type of fastening means has the advantage that it can generally be operated without tools to assemble and disassemble the cover.
    Such a lamp with spring lock is known from DE 195 05 471 A1. A cover in the form of slats is fastened in the light outlet opening of a lamp by means of spring clips. The spring clips can also be used to hang the cover on one side on a hook on the lamp housing, e.g. to perform electrical assembly work in the luminaire.
    However, the locking mechanism of the spring systems, as described above, is relatively complicated to handle because the spring elements have to be hooked onto the holding devices of the lamp, which complicates the fact that when the slats are mounted, a direct view of the holding devices for hanging the spring elements is not possible.
    There is therefore a need for a lamp with a spring-held cover, which makes it possible to carry out assembly work in the lamp, which can be closed as easily as possible.
    The task is solved by a lamp according to claim 1.
    A special feature of the luminaire according to the invention is that two differently designed spring elements are used on two opposite sides of the cover. One spring element comprises an elongated leg with a hook, which allows the cover to be suspended on one side on the spring element / 16 in a preassembled state. The opposite at least one second spring element, in contrast, has only one detent spring, which enables the cover to be simply snapped into place on the carrier structure. In the end position of the cover, the two spring elements act together to hold the covers on the support structure. On one side, the cover is held by the spring element with the elongated leg, the hook on the leg no longer having a supporting function in this position of the cover, while the cover is held by the catch spring on the opposite side.
    According to a preferred embodiment, the first and / or the second spring element on the support structure is mechanically inserted into recesses in the support structure or is attached to the support structure by separate fastening means. For example, the first and / or the second spring element can have a single or multiple angled section which is inserted into slots in the support structure and is supported therein. This embodiment has the advantage that no separate components are required for fastening the spring elements to the support structure. According to an alternative embodiment or in addition to the previously mentioned embodiment, separate fastening means such as screws or rivets can also be provided in order to fasten the spring elements to the support structure. For example, the first and / or the second spring element can also be attached to the support structure by heat welding with a plastic.
    According to a preferred embodiment, the cover has, on a side facing the support structure, webs which have openings or depressions which interact with the first and second spring elements. In particular, the cover can have symmetrical webs on both sides, each of which has at least one opening, which can interact with both forms of spring elements. However, the spring elements interact differently with the webs. The spring element with the elongated leg is, for example, inserted into the opening and can slide along it, so that the cover can be suspended from the hook of the elongated leg, while the leg slides along the leg for final assembly of the cover and the hook lies against the inside of the cover , As a result, the spring element with the leg can be used both for hanging down and for fastening the cover in the end position. The spring element with the detent spring can interact with a web of the same type / 16 on the opposite side of the cover. On this side, the spring element engages with the detent spring in the opening or recess of the web. For example, the web slides over a stop slope of the detent spring and engages with a recess under an edge of the opening or the recess in the web.
    According to a preferred embodiment, the cover has a non-transparent outer frame area, which at least partially blocks the view of the spring elements through the cover when the cover is assembled. The lights of the present invention are particularly suitable for relatively large and heavy covers which are held on the support structure by correspondingly massive spring elements. However, these spring elements would be visible through a completely transparent cover and can disturb the external appearance of the lamp when the cover is mounted in the end position. A non-transparent frame section is therefore preferred in the cover, which blocks the view of the spring elements. The light from the lamp only emerges from the area of the cover that is provided within the frame. Alternatively, it can also be provided that the frame is matt transparent or semi-transparent to light. In this case, the frame area can also contribute to the light emission. However, the view of the spring elements is blocked by the matt or partially translucent area of the cover.
    The frame section can also be used to cover further electronic or mechanical components of the luminaire in the support structure. For example, operating devices, electrical cables and the like can be provided in this area, which are then covered in the assembled state of the lamp, while these components are accessible in the state of the lamp in which the cover is suspended on one side from the support structure.
    According to a preferred embodiment, the luminaire has illuminants, in particular LEDs, which are mounted on the cover. As previously mentioned, the construction of the lamp is suitable for relatively heavy covers. In particular, the lamp according to the invention allows electronic components such as the lamps to be mounted directly on the cover. It is advantageous here that the cover can be suspended on one side on the support structure for preassembly. This is because it is then possible to electrically connect the cover provided with illuminants to a supply cable which is guided through the support structure. In particular / 16, the lamps can be mounted, for example, on a base plate that can be plugged into the cover. The spring elements according to the invention readily allow such a relatively heavy structure, i.e. a transparent cover including a base plate with lamps arranged thereon, to be mounted on the support structure solely by the spring elements.
    As an alternative or in addition, it is also possible for illuminants, in particular LEDs, to be provided on the carrier structure itself opposite the cover.
    According to a preferred embodiment, light-directing elements are also integrated in the cover, which are arranged opposite the illuminants. The light-directing elements in the cover can interact both with lamps on the cover and with lamps on the support structure of the lamp. The light-directing elements on the cover can comprise, for example, one or more reflectors, one or more lens elements and / or slats. The weight of the light-directing elements can be easily held on the support structure by the fastening according to the invention via the two different spring elements, without additional fastening means being necessary.
    According to a preferred embodiment, structures for holding illuminants and / or light-directing elements are attached to the cover, in particular the previously described illuminants or the previously described light-directing elements, latching lugs extending from the cover being clipped onto the structural elements, or Lugs that extend from the structural elements are clipped onto the cover. For example, the base plate with the lamps arranged thereon can be firmly clipped onto the cover by a plurality of latching lugs. The cover can also have reflectors and / or lens elements opposite the lamps. The entire structure, which essentially includes all lighting installations of the luminaire, is attached to the support structure by means of the spring elements.
    Further features and advantages of the present invention will become clear from the following description of a preferred embodiment, which is described in connection with the figures. The following is shown in the figures:
    / 16
    Figure 1 shows a cross section through an embodiment of a lamp.
    Figure 1a shows a spring element with detent spring in a perspective view.
    Figure 1b shows a spring element with an elongated leg in a perspective view.
    Figure 2 shows the lamp of Figure 1 in the right area, with the suspension is suspended.
    Figure 3 shows the illustration as in Figure 2, but the suspension is already half closed.
    Figure 4 shows the lamp of Figure 1 in the left area, the cover is almost completely closed.
    Figure 5 shows a cover of a lamp with a base plate with perspective
    Exploded view.
    Figure 6 shows the cover with base plate according to Figure 5 in a side view.
    An embodiment of a luminaire is described with reference to FIGS. 1 to 4. The lamp comprises a support structure 2 in the form of a housing. It is a housing that is suitable for ceiling installation. Alternatively, only one mounting frame can be provided as the support structure 2. The carrier structure 2 defines an open side downward over the entire cross section, apart from an edge region, which is closed with a cover 4. The cover 4 has the shape of a flat plate. As described later in connection with the embodiments according to FIGS. 5 and 6, however, further components can be attached to the cover 4.
    The cover 4 is held on the carrier structure 2 by two different types of spring elements 10, 20. The spring elements 10, 20 are shown in Figures 1a and 1b.
    / 16
    On the right side there are several, preferably three spring elements 10 (only one of the spring elements 10 can be seen in the cross section according to FIG. 1), which have an elongated leg 12 and a hook 14 at the end of the elongated leg 12. Furthermore, the first spring element 10 has a multiply curved section 16, which allows the spring element 10 to be inserted into cutouts on the support structure 2 in order to fix the spring element thereon. In this embodiment, no additional fastening means are required to hold the first spring element 10 on the support structure 2. The carrier structure 2 itself has an angled sheet-metal element which is riveted firmly in order to fix the first spring element 10 thereon in cuts. Alternatively, the spring element 10 could also be provided with separate fixed fastening means, e.g. with rivets, be attached to the support structure 12.
    On the opposite side of the support structure there are further preferably three spring elements 20 of a second type (only one of the spring elements 20 being visible in the cross section in FIG. 1). The spring elements 20 have a detent spring 22 which can be deflected elastically. The remaining sections of the second spring element 20 are formed by a section 26 which is in principle identical to the sections 16 of the first type of the spring element 10. The second spring elements 20 are fastened to the carrier structure 2 in the same way as described for the first spring elements 10.
    It is explained below how the cover 4 is fastened to the carrier structure 2 by means of the first and second spring elements 10 and 20.
    The cover 4 has at two opposite edges on the side of the support structure 2 a web 6 which has openings 8. The first spring element 10 is guided with the elongated leg 12 through an opening 8, wherein the elongated leg 12 can slide along the opening 8. Referring to FIGS. 2 and 3, it is shown how the cover 2 rests on the first spring element 10 in different positions. As shown in FIG. 2, the cover 4 can be suspended on one side on the first spring element 12. In this case, the cover with the opening 8 hangs on the web 6 in the hook 14. As shown in FIG. 3, the cover 4 can be pivoted into the support structure. The opening 8 slides along the leg 12. This movement can be continued until the cover is pivoted completely into the opening of the support structure 2, as shown in FIG. 1.
    / 16
    On the opposite side of the cover, as shown in Figure 4, the web 6 is snapped onto the detent spring 22 of the first spring element 20. The detent spring 22 comprises a run-on slope, which elastically deflects the detent spring 22 when the web 6 acts on the run-on slope. In the end position of the cover, the detent spring 22 engages with a recess in the opening 8 of the web 6, so that the cover is held firmly on the support structure 2 by the detent spring 22.
    Accordingly, the different spring elements 10 and 20 work together on both sides in order to fix the cover 4 to the carrier structure 2 for closing the open side. In contrast, only the first spring elements 10 act to suspend the cover 4 of the support structure in order to fasten the cover 4 to the support structure 2 approximately perpendicular to the underside of the support structure 2.
    An embodiment of the cover 4, which can be used in the lamp described above, is explained in more detail with reference to FIGS. 5 and 6.
    The cover 4 comprises a lower section which, as described above, has the webs 6, in which the spring elements 10 and 20 engage in order to fasten the cover in the carrier structure 2. In this embodiment, the webs 6 are designed as a peripheral edge, so that the cover can engage in the support structure 2 over the entire circumference of the peripheral web 6. On the inside of the cover 4, optical elements 44 are also integrated, which can be designed in the form of reflectors and / or lens elements. Furthermore, the cover 4 has a base plate 40 which is connected to the cover 4 by means of locking turf 42. In the embodiment shown, the base plate 40 has electrical connection means 46. Furthermore, 4 LEDs are attached to the base plate in the direction of the cover, which emit the light of the luminaire through the light exit surface through the cover 4 or through the optical elements 44 integrated in the cover 4.
    The cover in the illustrated embodiment therefore not only serves as a transparent cover for a lamp housing, but also includes the lighting components of the lamp. The relatively high weight of this cover 4 can easily be held by the spring elements 10 and 20 on the support structure.
    / 16
    It is particularly advantageous that the cover can be hung on one side on the support structure in order to connect the electrical connections 46 in the cover to supply cables (not shown) which are laid through the support structure 2. The cover 4 can then be brought into the final assembly position, as described above. The electrical connection cables lie above the cover 4 or the base plate 40 in the support structure 2.
    Numerous modifications of the lamp described above are possible within the scope of the invention, which is defined by the claims. For example, the illuminants can also be mounted in the support structure itself and emit the light through the cover. Furthermore, the cover is preferably not transparent in the region of the edge, so that the spring elements which bear against the cover are not visible from the outside. The light exit surfaces of the lamp can be limited to partial areas of the cover. In the illustrated embodiment of Figures 5 and 6, e.g. all areas of the cover 4 in addition to the optical components 44 are not transparent. The cover can also be semi-transparent, so that it forms a uniformly illuminated surface.
