Definitions
- the present invention relates to a luminaire cover, which is intended for use in an elongate lighting arrangement, in particular in so-called light bands.
- a light band is understood to mean a lighting arrangement which extends continuously over a very great length in comparison to individual lamps.
- Such light bands can be used both as an installation variant as well as in the form of surface-mounted lights or suspended lights.
- they have a support element extending over the entire length of the arrangement, which consists of several segments or modules and serves for mounting or arrangement on or in the ceiling as well as the position of all essential components for the light emission.
- such carrier elements are U-shaped, wherein the longitudinal channel formed in this case serves to accommodate the light sources and the operating devices required for operating the light sources.
- the underside of the channel is then closed by a cover, which forms the Lichtabstrahlfiambae the light band and has corresponding optical properties to realize the light output in the desired manner.
- the cover can be designed both light scattering and include components that help the light targeted in certain
- the present invention is therefore based on the object to provide a novel solution for the realization of a corresponding lamp cover for the elongated lighting arrangements described above, in which the one hand said problems are avoided and on the other hand satisfies the quality of the light output with the help of Lichtabstrahlelements highest standards.
- a light cover which has the characteristics of
- the solution according to the invention is based on the idea of integrally forming the cover over the entire length of the light band, however
- the cover consists of an elongated, plate-shaped Lichtabstrahlelement, which is formed substantially flat. On both sides of the cover
- light-emitting elements are arranged fastening profiles, with the aid of which an attachment to the lamp housing takes place.
- the Fixing profiles formed of a material which is more flexible than the material of the Lichtabstrahlelements.
- the invention proposes a luminaire cover for an elongate lighting arrangement which has a substantially plate-shaped, elongated light-emitting element and fastening profiles arranged on the longitudinal sides of the light-emitting element, which are used to fasten the
- Luminaire cover are provided on a lamp housing, wherein the
- the solution according to the invention makes it possible to manufacture the luminaire cover according to the invention in any desired lengths, in particular also endlessly.
- the decisive advantage, however, is that due to the plate shape of the
- Lichtabstrahlelements and the different choice of materials for the components of the lamp cover the possibility exists to bend the cover at least to a certain extent and thus also to roll up. When rolled up, even an extremely long light cover can be easily transported to the place of use and, where appropriate, shortened to the required length. This opens up the possibility of realizing a one-piece light cover extending over the entire length of a light band. At the same time, a material can be selected for the light emitting element, which meets the optical requirements with respect to a high-quality light output.
- the fastening profiles extend over the entire length of the Lichtabstrahlelements.
- they can each form one or more webs which are aligned substantially perpendicular to the plane of the light emitting element. Even in this configuration, the previously described rolling up of the lamp cover is still possible because the flexibility of the material for the
- the fastening profiles could be formed of a rigid material or of the material of the light-emitting element, a corresponding rolling up of the cover would be impossible and it would again the problem exist that the cover can be transported only in the extended state, which - as mentioned above - from certain lengths is almost impossible.
- the optically active hard component ie for the
- Lichtabstrahlelement is preferably PMMA or PC or other material used, which has suitable optical properties and the
- PMMA and PC are materials that are widely used in lighting technology to realize light emitting elements. In any case, these allow
- thermoplastic elastomer whose optical properties are irrelevant to the luminaire cover. At the same time, however, this material is sufficiently flexible to allow the cover to roll up.
- Cover and luminaire housing can be achieved. This also means that with the help of the cover reliably the ingress of dirt, dust or
- the light emitting element can be provided with a light-influencing structure. This can be formed for example by a glued foil.
- Fig. 1 shows schematically a view of a lighting system
- FIG. 2 is a cross-sectional view of the light band system of FIG. 1;
- Fig. 3 shows the embodiment of the lamp cover according to the invention in
- 5 and 6 are views of another embodiment of a

- Figure 1 shows a typical application of a light strip, in which the luminaire cover according to the invention is used. That with the
- Reference numeral 1 provided light band is provided here as an installation variant and serves to illuminate an elongated space 100, for example, a passage over its entire length. Due to the ceiling installation, only the underside of the lighting system 1 is visible. Strictly speaking, for a viewer only the elongated light cover 20 visible, on which light to
- the light cover 20 can influence the light when dispensing in a suitable manner, either to emit light in a very wide angular range or diffuse light or to emit light in specific directions.
- the prerequisite for this is that the material of the cover 20 has corresponding optical properties, which is the
- FIG. 1 A basic structure of a lighting system 1 in sectional view is shown in FIG.
- Main component is an elongate housing 2, which is the recording of all serves important components.
- Schematically represented in the present case only two light sources 3, which are located in the interior of the lamp housing 2.
- the elongated receiving space of the approximately U-shaped housing 2 also serves for the storage of suitable operating devices for operating the light sources 3 and the lines for the power supply.
- fluorescent lamps 3 are shown as light sources, which are arranged behind one another over the entire length of the light band system 1 in order to emit light over the entire length.
- other light sources in particular LEDs could be used.
- Luminaire cover 20 closed the design of this cover 20 and its attachment to the housing 2 will be explained in more detail below.
- the arrangement of the cover 20 on the housing 2 takes place such that the cover 20 is flush with the underside of the ceiling 110 of the space 100.
- the assembly of the entire assembly 1 is done with the help of
- Mounting brackets 10 which are screwed on the one hand to the ceiling and on the other hand are coupled at its center leg 11 with the housing 2 of the light band 1.
- the housing structure 2 of the light band 1 is usually formed from a plurality of interconnectable segments or units. As a result, it is possible to realize strip lights of virtually any length, with only a corresponding number of segments or units having to be joined together or arranged one behind the other.
- the modular design of the housing 2 does not have a negative effect on the appearance of the light band 1, since only a view of the viewer in the illustrated embodiment, the light cover 20 is visible.
- a luminaire cover is now provided, which can be realized almost endlessly, but in particular can be adapted in any way to the length of the lighting system 1.
- the light cover 20 is designed such that it can not only be made relatively simple but also can be transported without much effort to the site.
- the cover with regard to the materials used, satisfies the requirements with regard to the desired light output of a continuous row lighting system 1.
- the inventive design of the lamp cover 20 is shown in Figure 3, wherein here the housing 2, in particular its lower end portion is shown and attached to the housing 2 cover 20.
- the cover 20 itself consists of two different components, on the one hand the elongated light exit element 21, via which the light output of
- these attachment profiles 25 are used to attach the cover 20 to the housing 2.
- they have a U-shape, wherein the middle leg 26 and the outer side leg 27 respectively for locking or jamming with the lower profiled area of the lamp housing 2 is provided.
- the outer side leg 27 is jammed with a slight projection 7 of the housing 2 or a corresponding pullback, where appropriate, the
- Design of the housing 2 and the configuration of the mounting profiles 25 could also be chosen differently, as described below with reference to a
- Lichtabstrahlelement 21 and mounting profile 25 - consist of different materials.
- a material is selected for the optically effective Lichtabstrahlelement 21, which is suitable for a corresponding effect on the light output.
- PMMA and PC come into question.
- Other materials would be conceivable, as long as they lead to a certain inherent stability of the Lichtabstrahlelements formed therefrom.
- the Lichtabstrahlelement 21 due to the plate shape limp, that is, it can be at least slightly bent in two dimensions, which - as explained in more detail below - is essential for the optimal transport properties of the lamp cover 20 of the invention.
- the material of the fastening profile 25 is significantly more flexible than the material for the light-emitting element 21, wherein a thermoplastic elastomer is preferably used.
- This increased flexibility in the fastening profiles 25 brings on the one hand the advantage that a simpler fastening of the cover 20 is made possible on the housing 20 and at the same time - for the advantageous case that the fastening profiles 25 completely over the entire length of the
- Luminaire cover 20 extend - an optimal seal between the housing 2 and the cover 20 is achieved, so that the ingress of dust or moisture is avoided at the interface. This makes it possible, with the aid of the cover according to the invention, to realize luminaire constructions of a so-called higher degree of protection,
- the flexibility of the fastening profiles 20 allows them to be bent relatively easily despite the fact that they have a plurality of differently oriented legs, which in particular are also aligned perpendicular to the plane of the light exit element 21.
- Trunking system 1 can be transported. As can be seen in the illustration of Fig. 4, while the side surfaces of the roller are made by the more flexible material
- the fastening profiles fulfill the function of spacers, by which the superimposition of the rolled-up layers of the light-emitting element is prevented, which additionally reduces the risk of damage during transport.
- the light emitting element 21 does not necessarily have to be completely flat or planar, but may well have a certain profiling, eg a slight curvature or the like. It is only essential that by this profiling or shaping the
- Flexibility is not limited too much, so that the cover can still be rolled up in the context of the present invention.
- the lamp cover 20 is transported in the rolled-up state to the site and then optionally cut to the required length corresponding to the length of the lighting system 1, is cut off. In a simple manner, then the cover 20 at the bottom of the
- Luminaire housing 2 are attached, so that over the entire length integrally extending cover is created. It is particularly advantageous in this case if the fastening profiles 25 extend completely over the entire length, since an attachment of the cover 20 is achieved at each point of the housing. This is relevant insofar as after unrolling the cover 20, this may possibly still be slightly bent and with the help of the fastening profiles 25, the remaining tension is absorbed, so that the cover 20 as desired rests straight on the housing 2 and thus flush with the ceiling underside ,
- the cover 20 may be light due to temperature variations compared to the housing 2
- a production of the lamp cover 20 according to the invention is preferably carried out in the so-called co-extrusion process.
- the cover can first be produced in almost endless length.
- opposite light inlet side - has a certain structuring, by which the light output is influenced in a certain desired manner.
- elongated structures such as e.g. elongated prisms or grooves are introduced into the surface of the light exit element.
- transverse structures it would be possible, for example, to form them by means of a foil which is applied to the light exit element, e.g. is glued.
- FIGS. 5 and 6 show, as a further exemplary embodiment, a corresponding luminaire cover 20, in which the surface of the light exit element 21 facing the luminaire housing is provided with a corresponding structure 30.
- This indicated structure 30 consists in the case illustrated of mutually crossed
- the structure is preferably formed by a film which is placed on the corresponding side of the
- Light exit element 21 has been masked. Again, however, the
- Inventive light cover 20 are wound in total to the role shown in Figure 4.
- the lateral attachment profiles 25 are designed somewhat differently and now have approximately a V-shape in cross section. On the one hand, this shape also allows the light cover 20 to be rolled up and, on the other hand, allows it to be fastened to a luminaire housing, such as FIG.
- FIG. 7 shows. On both sides of the cover in this case narrower shadow gaps 5 are formed, as is the case in the embodiment of Figures 1 to 4.
- the cross-sectional view of FIG. 6 also shows a particularly advantageous embodiment of the light exit element 21 and of the attachment profiles 25 in the connection area. Because one of the two components - here the
- Fixing profiles 25 - has a web with 28 undercuts, which is enclosed by the other components, a special good connection achieved through a lasting cohesion despite the different
- a luminaire cover is provided with the invention, which can be easily adapted to any length of a lighting system. Due to the choice of material according to the invention here also the transport of the cover at its place of use no longer represents a problem. At the same time, however, it is ensured that materials are used for the optically relevant components which satisfy the corresponding requirements.
- the use of the cover according to the invention is not limited to installation variants. Of course, it can also be used for mounting variants or suspended light strips.
