Lampshade I. Area of application

&iacgr;&ogr; The invention relates to lamps and the lampshades usually used to cover the light source.

II. Technical background

The classic design of such lampshades consists of a wire frame onto which a covering, particularly made of textile material, is applied, which partially lets the light through, but attenuates it to such an extent that the viewer looking into the light source is not blinded.

In the case of floor lamps or table lamps, such a lampshade often has the shape of a cylinder or truncated cone.

Instead of textile material, a film material, especially made of plastic, and especially dyed or printed in color, is often used.

It is already known that optical effects can be achieved by designing this covering accordingly.

For this purpose, coverings made of textile material were used, which, due to their weave, for example, had specific openings, or perforated foils.

·

It is also already known to use the covering as a carrier material for objects applied to it, for example individual fringes made of textile material, straw or similar material, or for gluing on natural objects such as leaves.

However, these were all objects that had no special optical effect other than blocking the light from the lamp.

&iacgr;&ogr; III. Description of the invention

a) Technical task

It is therefore the object of the invention to provide a lampshade which, in addition to its normal function of light attenuation, produces an additional optical effect, preferably caused by the light source of the lamp.

b) Solution to the task

This object is solved by the features of claim 1. Advantageous embodiments emerge from the subclaims.

The optical effect of the effect bodies, which are preferably relatively small and arranged in large numbers on the carrier material of the lampshade, consists either in the partial translucence of the effect bodies or in the mirrored or ground outer surface, especially in the case of completely opaque effect bodies, or in both effects simultaneously.

In the case of partially translucent effect bodies, the light from the lamp shines through them from the inside to the outside and, if necessary, the light is also reflected on the ground and, if necessary, colored vapor-coated outer surfaces, in particular the

faceted, ground outer surfaces, broken. Effect bodies made of glass or lead crystal are best suited for this.

In contrast, opaque effect bodies whose outer surfaces are merely mirrored and/or ground as described above, in particular ground in a facet-like manner, can also be made of metal, but also of glass or plastic, with the mirroring being achieved in particular by vapor deposition with metal.

&iacgr;&ogr; The optical effect of such opaque effect bodies is that light hits the mirrored or polished outside of these effect bodies and is reflected from there or is reflected by different colors. On the one hand, this is of course ambient light, but on the other hand it is also the light from the lamp's light source, which, for example, penetrates the carrier material of the lampshade next to the respective effect body and is redirected by one of the neighboring effect bodies, in particular its side surfaces, onto the particularly flat, curved, lens-shaped outside of the respective effect body.

The effect bodies, in particular rhinestones, preferably have a lens-shaped or semi-lens-shaped cross-section or a plate-shaped cross-section, and preferably a flat back.

The flat back facilitates attachment to the convexly curved outside of the carrier material of a lampshade, which can preferably be done by gluing, for example by ironing on using a hot glue or by simply pressing on a self-adhesive glue, or by sewing on.

Preferably, the plurality of effect bodies is arranged in a specific ornament or pattern, which is applied as a whole to the carrier material by the individual effect bodies being previously arranged with their outer side adhering to a holding film and thus by pressing the

The entire holding film is pressed against the outside of the carrier material, all with a self-adhesive backing - if necessary after removing a protective film that runs over the entire ornament - can be pressed onto the carrier material and thus glued on.

The carrier material often consists - on the one hand for reasons of better durability, on the other hand for reasons of heat resistance of the lampshade - of several layers, namely an inner layer made of a stiff, translucent plastic film as a supporting layer, which is in particular attached to the frame of the lampshade or can be dimensionally stable on its own, and on which the corresponding structural layer, for example made of textile material, which would not itself be dimensionally stable, is applied, in particular glued.

The effect bodies are preferably applied to the outside of the carrier material. However, a particularly beautiful effect can also be achieved with opaque, mirrored and/or ground effect bodies on the outside, especially faceted ones, by applying these effect bodies - at least or only on the side of the lampshade facing away from the viewer with respect to the light source - to the inside of the carrier material and from there reflecting the light from the light source forwards towards the viewer.

For this purpose, it is particularly recommended to divide the lampshade into a small lamp cover on the viewer's side and a lamp reflection surface on the back side facing away from the viewer behind the lamp, instead of a lampshade that completely surrounds the lamp when viewed from above.

In the case of a lampshade made conventionally from a wire frame, the effect bodies can be applied to the inside of the carrier material in a simple manner by applying the effect bodies to a stiff but flexible spreading film that fits precisely

cut to size and spread between two adjacent bars, in particular vertical bars, of the lampshade, for example in the wedge-shaped space between the vertical bar and the carrier material applied to the outside of it.

c) Examples of implementation

Embodiments according to the invention are described in more detail below by way of example. They show:

&iacgr;&ogr; Fig. 1: a table lamp with lampshade according to the prior art,

Fig. 2: a lampshade according to the invention in plan view,

Fig.3: an ornament made of effect bodies,

Fig. 4: a section through a lampshade according to the invention,

Fig. 5: a plan view of a lampshade according to the invention and

Fig. 6: a plan view of another form of a lampshade according to the invention.

Fig. 1 shows a conventional table lamp with a plate-shaped base from which a column rises, at the free upper end of which is located on the one hand the socket for the light source 3 in a G9 bulb and on the other hand the clamp for the inner ring 6b3 of the lampshade 2. Usually, such frustoconical lampshades for covering with a non-dimensionally stable material are made from a frame 6 made of strong metal wire, in which an upper and a lower wire ring 6b2 and 6b1 are kept at a distance in the vertical by individual vertical rods 6a placed between them and distributed over the circumference, each of which is fastened, in particular welded, with one end to the upper and the other to the lower wire ring 6b1, 6b2.

In addition, an inner ring 6b3 is concentrically connected to the lower, outer wire ring 6b1, preferably in the plane of the latter, via radial rods 6c.

While in Fig. 1 this frame 6 of the lampshade 2 is shown covered with a transparent carrier material 5 for reasons of clarity, in practice a carrier material that is only partially transparent to light is selected for the covering, which makes the frame 6 no longer visible, especially when the lamp is switched off.

In this state, Fig. 2 shows a lampshade in the front view in the state according to the invention, i.e. occupied with effect bodies 4.

Ø As Fig. 2 shows, a large number of small effect bodies 4 are preferably used in comparison to the dimensions of the lampshade, and the effect bodies 4 are arranged on the carrier material 5 of the lampshade 2 - preferably not randomly but in the form of a predetermined pattern or ornament 40a, b, as can be seen in Figs. 2 and 3.

Fig. 4 shows in a sectional view, on the one hand, the cross-sectional shape of the effect body 4, namely preferably flat, in particular plate-shaped as in the case of the effect bodies 4e, or lens-shaped or semi-lens-shaped as in the case of the effect bodies 4a and 4c. The effect body 4b, in contrast, protrudes further from the carrier material 5 and, in particular at a distance from the carrier material 5, has a larger cross-section than at the contact surface, in particular adhesive surface, opposite the carrier material 5, while this particularly flat rear side 7 is preferably the largest transverse dimension of the effect body 4.

As can be seen from the effect bodies 4a - 4c, the effect bodies on this back side 7 are preferably glued to the carrier material 5 over their entire surface, whereby this can in particular be a hot glue which is heated by ironing on, in particular from the opposite side of the carrier material facing away from the effect body 4, in order to lead to the bonding.

Using the plate-shaped effect bodies 4e, the fastening by means of sewing, in particular overlapping in a scale-like manner, is alternatively shown.

As can already be seen from Figs. 2 and 3, within an ornament 40a there can be the same effect bodies 4, or different types of effect bodies 4a - 4d, as can be seen from the ornament 40b of Fig. 3.

Fig. 5 shows in a top view of a lampshade 2 having a frame 6 that the effect bodies 4 are attached to the outside of the carrier material 5, i.e. the side facing away from the light source 3. In the rear area between the two vertical bars 6a of the frame 6, however, the arrangement on the inner surface of the carrier material 5 facing the light source 3 is also shown:

The arrangement is carried out indirectly in that the effect bodies 4 - this time of course with their back facing outwards and with their mirrored and/or ground outer surface facing the light source 3 - are applied, in particular glued, to a spreading film 11, and this spreading film 11 is still somewhat flexible, but has such a high inherent rigidity that, when cut to a precise fit, it can be inserted, in particular spread, between the covering of the carrier material 5 applied to the outside of the frame 5 and the two adjacent vertical rods 6a of the frame after the effect bodies 4 have been fitted.

Fig. 5 also shows that in this way it is also possible to arrange effect bodies (e.g. 4c) in the same positions on the inside and outside of the carrier material 5, i.e. in particular to apply the identical ornaments or patterns on the inside and outside, or only on the inside or only on the outside, in particular on different peripheral areas of the same lampshade. It is of course recommended to attach them to the outside of the carrier material on the side facing the viewer and to attach them to the inside of the carrier material 5 on the side of the lampshade facing away from the viewer in order to achieve the optimal optical effect for the viewer.

Fig. 6 shows a solution in which the two effects of the light passing through effect bodies 4 on the one hand and the reflection of the light on the effect bodies on the other hand are divided by the fact that instead of the lampshade 2 surrounding the lampshade 2 in the top view, the lampshade is divided into a front shield 2' on the side of the lamp 3 facing the viewer and a rear reflection area 2" on the back of the lamp 3 facing away from the viewer. Shield 2' and reflection area 2" can be designed together as a unit and in particular according to

&iacgr;&ogr; of conventional design have a frame 6 made of wire, the frame 6 having an inner ring 6b3 for clamping to the socket of the lamp 3, from which the frame of the front shield 2' as well as the frame of the rear reflection area 2" are held via radial struts 6c.

In this case - as shown in the right half of Fig. 6 - the rear reflection area 2" can be convexly curved towards the viewer, as is preferably also recommended for the front shield 2', or - as shown in the left half of the image - the rear reflection area 2" can also be slightly concavely curved towards the viewer.

In both cases, both the shield 2' and the reflection area 2", which are each also covered with a carrier material 5, are each covered with effect bodies 4, preferably only on the side facing the viewer, i.e. on the outside of the shield 2' and on the inside of the reflection area 2", with respect to the light source 3.
