Description

Illuminator and lighting device

Technical Field

The invention relates to a lamp (or luminaire), in particular a desk lamp, having an umbrella-shaped lamp body, which lamp has at least one lighting element integrated into the lamp body, which lighting element emits light in at least one downward direction in the position of use.

Background

There are high demands on the design, light quality, light color and glare-free, of lamps, especially of desk lamps, such as lamps in dining tables or dining tables in restaurants (usually in addition to or instead of candles) or in private sectors.

Furthermore, from a sustainable development point of view, it is now common for people to reuse daily necessities, especially in quite unusual situations.

Disclosure of Invention

The invention is based on the object of creating a lamp of the initially mentioned type which combines high-quality, glare-free dining table or dining table illumination with interesting and versatile designs, while exhibiting a visible and novel contribution to material recycling.

The aforementioned object is achieved by a lamp having the features of claim 1 or a lamp device having the features of claim 15. Furthermore, a rod-shaped element according to claim 16 and an alternative connection element according to claim 17 are proposed.

Advantageous embodiments of the invention are explained in the dependent claims.

According to the invention, in a lamp of the type mentioned at the outset, provision is made for the lamp body to have a rod-shaped (or handle-shaped) element on its underside, which element is designed to fix the lamp in the neck opening of a commercially available bottle.

In this context, it should be emphasized that-also for the following explanation-reference to a commercially available bottle does not represent the actual part of the lamp according to the invention; instead, the lamp is designed to advantageously cooperate with such a bottle.

This means that the lamp can use almost any (unsealed) bottle, which functionally acts as a lamp holder as long as the diameter of the neck is compatible with the rod-shaped element.

For example, simple unlabeled glass bottles (wine or mineral water bottles) may be used, but champagne bottles, beer bottles, wine bottles, "belly bottles" type bottles, etc., each with or without a label (with a separated label or an otherwise non-existent label), each made of white or colored glass, may also be used.

Furthermore, according to the invention, it is provided that the lighting element has at least one lighting element ring or collar arranged around the rod-shaped element. The ring or collar may be formed by a single light emitter (in particular an LED) with a specific angular distance, whereby from three LEDs with an angular distance of about 120 ° onwards it may emanate from the ring or collar; however, it is preferred to provide significantly more individual light emitters. Alternatively or additionally, one or more linear LEDs may also be used.

Furthermore, according to the invention, it is provided that the lighting element or at least one lighting element is positioned above the rod-shaped element or in the base region of the rod-shaped element or above a front end of the rod-shaped element, which front end faces away from the lamp body, with respect to its height position.

Finally, the annular or ring-shaped lighting element (or at least one lighting element if a plurality of lighting elements are provided) should not be located below the end face of the rod-shaped element in terms of its height position, which is a positioning along an imaginary central axis extending through the centre of the rod-shaped element, but should preferably be located above the rod-shaped element or approximately at or slightly below the height of the mounting base of the rod-shaped element.

The arrangement of the illumination element substantially above the rod-shaped element, and thus generally above the bottle opening, has the advantage on the one hand that in the case of a normal bottle height and a normal table height, the lamp as a whole is still at a height at which the lower illumination element cannot be seen directly, even from a normal sitting position angle (no glare), but still illuminates the surrounding area in an optimal manner.

Furthermore, according to the invention, when the lamp is positioned "high", the bottle itself, including any label on the neck of the bottle, is largely visible, even additionally illuminated, so that the invention can also be advantageously used for visually highlighting the bottle, for example for wine display and the like. Existing structures at the bottleneck (e.g. glass threads or coloured capsule film portions around the bottleneck portion) can be highlighted particularly effectively by illumination.

Finally, by creatively arranging the lamp above the bottle mouth, it is advantageous that the light is generally irradiated to the edge of the bottle neck.

This light input into the front edge creates a light guiding effect (transmission of light by multiple total reflections), which results in internal luminescence of the bottle glass or any bottle contents, resulting in interesting optical effects, especially in the case of glass bottles.

In an advantageous embodiment of the invention, the rod-shaped element is tapered at least partially on the outside, preferably with a taper angle of 4 ° or more, particularly preferably 5 ° or more. These taper angles are relatively high for the stopper and can be used for a wide range of neck diameters, but tend to compromise the stability of the rod-like element in the neck, and therefore further measures should generally be provided to improve the friction fit.

For this purpose, the rod-shaped element can be formed at least on its outer side from a rubber-elastic material, preferably from a silicone elastomer, wherein the rod-shaped element is particularly preferably formed essentially entirely from a silicone elastomer.

Furthermore, the rod-like element may preferably have a recess leading to its free end.

Due to the recess leading to the free end, the lamp body may be attached in an alternative way without conversion, e.g. it may be placed on a suitable rod or post. The rod-shaped element designed in this way allows to be fixed by actively or loosely surrounding the outer contour (when inserting the neck of a bottle) and by actively or loosely engaging in a recess provided in the rod-shaped element (for example by attaching it to the rod), i.e. by the inner contour of the rod-shaped element.

Such a recess also increases the material spring effect of the rod-like element, as it becomes compressible to a certain extent by the recess. Furthermore, the concealed fastening screw can be accessed through the recess.

The recess may not extend to the bottom of the rod-like element, but may terminate or taper at a higher position (e.g. the recess may enter a rather narrow through hole for the fastening screw). This stabilizes the part of the rod-shaped element on the lamp body side that is not "hollowed out" by the recess, so that the deformation of the rod-shaped element can be limited or controlled.

It is particularly advantageous if the rod-shaped element is tapered on the outside with a recess opening into the free end of the rod-shaped element, which recess does not have to extend to the bottom of the rod-shaped element, and which rod-shaped element is composed of an elastic material at least in the region of the recess.

As a result, when the rod-like element is fixed in the neck opening of a commercially available bottle, it can be compressed a predetermined amount, whereby a reliable friction fixation in the neck opening and/or adaptation to a non-circular neck opening can be achieved. When the bottle neck is inserted, a pretension is automatically created in the bottle neck due to the compression, which ensures a very reliable friction fit in the bottle neck, but can also be released again easily.

Furthermore, by this design of the rod-shaped element, a temporary sealing of the bottle can be achieved, whereby the lamp according to the invention can also be used as a temporary bottle cap, for example for carbonated beverages, given that the rod-shaped element material is food safe, as is the case in the preferred embodiment.

The dimensions of the rod-shaped element are preferably such that an optimal holding force is ensured in the various usual bottle neck diameters, the rod-shaped element preferably being designed to be significantly shorter than is typical of lamp holders, for example conventional light-shielding lamps, since the lamp holders are preferably formed by the bottle itself.

In an advantageous embodiment, the rod-like elements may have one or more of the following dimensions or material properties, provided that they are compatible with each other:

the length of the rod-like element corresponds to 30% to 100% of the total height of the lamp body, preferably 25% to 50% of the total height of the lamp body; and/or

The overall length of the rod-like element is between about 30mm and about 50 mm; and/or

The outer diameter of the rod-like element (optionally conically tapering towards the free end) is between about 10mm and about 25 mm; and/or

The outer diameter of the rod-like element tapers from a diameter of between 19mm and 22mm on the lamp body to a diameter of between 15mm and 18mm at the free end; and/or

The rod-like element has a central longitudinally extending recess which opens into the free end and has a diameter of between 5mm and 12 mm; and/or

The rod-like element has a central longitudinally extending recess which opens into the free end and which extends only about 30% to 60% of the length of the rod-like element; and/or

The rod-shaped element is made of a food-safe material.

In a preferred embodiment, at least one lighting element integrated into the lamp body has rings or rings, each formed by at least three, preferably more than three individual light-emitting diodes uniformly distributed over the circumference and/or by at least one linear LED, whereby the main radiation direction of the LED points downwards.

The at least one lighting element formed by the annular or ring-shaped light emitters preferably has a ring or ring radius of about 3.5cm such that its ring or ring radius is smaller or not significantly larger than the radius of a conventional bottle, in particular a wine bottle, which ensures that the lighting element is capable of illuminating the neck and shoulder structures of the bottle. A typical narrow bottle (0.75 liter) has a minimum radius of, for example, about 3cm (diameter about 6 cm). Thus, given the tolerances, the dimensions mentioned above result, whereby a particularly suitable radius of the lamp ring is approximately 3cm.

Due to the already mentioned "high" positioning of the lamp, in a preferred embodiment of the invention the bottleneck area is not covered by the umbrella-shaped lamp body or may only be slightly covered in the mouth area of the bottleneck area, the light may radiate downwards in a ring or loop. The light source is reflected from the upwardly tapering bottleneck surface into the surrounding space, which results in an interesting optical effect. The lamp according to the invention thus has a different lighting effect than conventional due to the reflective surface comprising the bottle, otherwise a similarly sized desk lamp is simply arranged on the pole.

In an embodiment, a battery or rechargeable battery element may be integrated into the lamp body, by means of which battery or rechargeable battery element at least one lighting element may be powered wirelessly.

Considering the power requirements of current LEDs, the fact that such a desk lamp is used as a selective illumination with a rather low light output, and considering the currently available battery technology, continuous operation times of several hours can be easily achieved with ordinary batteries.

If this is not enough, the "empty" lamp can be replaced very easily and quickly by a charged lamp (just as a candle is replaced). It is also conceivable that, especially for outdoor use, the solar cell may be arranged e.g. on top of or outside, which will ensure solar charging of the cell.

In an embodiment, the umbrella-shaped lamp body may be made of an opaque material such that the lamp emits light substantially only downwards. In this case, this is in contrast to conventional desk lamp covers (e.g. made of coloured glass), which are typically partially transparent, allowing a small amount of light from the lamp to pass through in a "glow" form. However, the latter, i.e. the transparent or partly transparent design of the side surface of the lamp body, is also conceivable according to the invention.

The term "umbrella-like" lamp body does not mean that it must have the classical shape of a lamp shade, which corresponds to a conical portion tapering conically upwards.

Of course, for example, a purely cylindrical or inverted conical shape is also possible. The basic shape of the lamp body is not necessarily circular, but may also be oval or polygonal-based.

It is finally important that there is a certain protrusion towards the bottom of the bottleneck diameter, i.e. in principle a spherical shape of the umbrella-shaped lamp body is also possible, or that a pattern or object, such as a champagne cork, can be reproduced in an enlarged form.

In an embodiment, the umbrella-shaped lamp body is preferably circular in top and bottom view, at least one button-shaped or contactless switching element being provided on its top side for switching on/off at least one lighting element and optionally for adjusting the brightness and/or the light color. The switching element may also be located elsewhere (e.g. unobtrusively attached to the underside of the lamp body) if desired.

Particularly preferably, the lamp is splash-proof and/or prevents foreign objects from entering, so that outdoor use is free of any problems. In general, the lamp may be designed according to a protection level IP44 (corresponding to the usual protection level of a wet room), which in a preferred embodiment may be achieved by manageable design effort due to the relatively few structure-related joints that need to be sealed.

Alternatively or additionally, it is conceivable to make a distinct central lighting control by means of a remote control (by means of an ISM band radio receiver or, for example, by means of WLAN or bluetooth). This more differentiated control option is of particular interest if RGB or RGBW leds can also be used to adjust the light color. It is also contemplated that there may be an automatic on/off switch or automatic brightness adjustment based on a signal from the ambient light sensor.

It is also conceivable to integrate one or more speakers into the lamp housing, preferably on the underside of the area where the leds are not needed, which can be solved by means of an audio stream (WLAN/bluetooth etc.) from the integrated energy storage device, so that sound can be provided to the table community-surround sound can also be provided by using a plurality of speaker lamps. Of course, it is also conceivable to implement such an acoustic function without an illumination function. A bass reflex opening may also be provided at the top of the lamp body to improve sound quality.

Finally, within the scope of the present invention, a lamp device (or "kit") is proposed, comprising a lamp (lamp body) of the aforementioned type and a suitable bottle as a lamp holder, the lamp being fixable in the neck of the bottle with a rod-shaped element.

Such a "kit" eliminates the need for the user to find or select a suitable bottle, although the user may always use the "own" bottle if he likes.

Furthermore, the kit may comprise a base with a holding rod which cooperates with a recess in the rod-like element, and the fixed charging and/or voltage source may be connected via contacts at the end of the holding rod which may be in contact with suitable contacts inside the rod-like element, for which purpose the holding rod may typically be powered by a holder with a low voltage power supply or its own battery. Alternatively, inductive charging may also be achieved by means of a corresponding coupling coil incorporated into the lamp housing.

For example, the invention is also applicable to certain beverages (wines, etc.) provided in an event by displaying the corresponding bottles in a novel way.

Because the lamp according to the invention can be easily separated from the "carrying bottle", the lamp according to the invention can also be used "purely" for other lighting purposes, i.e. without a bottle as a support, for example by "reversing" the lamp shade, as a "headlight" for temporarily illuminating objects or signs from below or from the side, or by placing it on the outer surface of the lamp shade, so that the lamp is illuminated upwards at an angle like a small spotlight for specifically illuminating certain objects.

Thus, the rod-like element in the lamp according to the invention can simultaneously fulfil a number of functions:

loose or form-fitting fixation for the lamp in the bottle;

-if necessary, as a stopper for bottles containing consumable contents;

for loose or form-fitting fixation of the lamp on the rod (using recesses); and

used as a handle to facilitate transportation (e.g. charging) of the lamp without leaving fingerprints etc. on the lamp body.

The rod-like element described above may be designed to be easily connected to and disconnected from the lamp body by the user, for example by means of a screw connection, a clip or a bayonet lock, and may also be provided as a separate optional accessory for securing the lamp body in the neck of a standard bottle. The rod-like element may preferably have the features described above, in particular a conical hollow cylindrical product made of a preferably food-safe silicone elastomer, the overall length of which is much shorter than the height of the lamp envelope.

Furthermore, it is conceivable that the respective lamp body is equipped with a conventional holding rod (possibly with a bracket), which in the sense of the invention is releasably secured in the rod-shaped element on the lamp side, so that the user can easily convert the lamp into a fixation in a commercially available bottle.

Furthermore, an alternative connection element is proposed which can be connected to the umbrella-shaped lamp body of the lamp instead of the rod-shaped element described above (for example by means of a screw connection). The alternative connecting element is adapted to fix the lamp body in the neck opening of a commercially available bottle closed with a (natural or artificial) cork by means of a screw in the form of a screw which can be screwed into the cork material several turns for fastening until a sufficient holding force is obtained.

FIG. 2 is a schematic view of the lamp according to FIG. 1 in a condition removed from the bottle;

fig. 3a and 3b show schematic bottom views of the lamp of fig. 2 according to the invention; and

fig. 4 is a schematic cross-sectional view of a rod-like element having a recess.

Detailed Description

The lamp, generally indicated at 10 (irrespective of the bottle 12 used as a support), has in the exemplary embodiment a typical conical lamp shade shape, although as mentioned above, other shapes (cylindrical, polygonal, hemispherical, etc.) are possible.

The bottles used are generally empty. However, if the rod-like element is designed to be suitable for food, it is also possible to close a completely or partially filled bottle with a lamp shade. If desired, the bottle may be filled with at least water or a coloured liquid in order to increase stability on the one hand and to achieve an additional optical effect through the illuminated liquid interface on the other hand.

The lamp 10 has a lamp body 16, in the interior 24 of which lamp body 16 a circumferential LED ring or LED ring (shown schematically) -also referred to as a lighting element 20-is provided, the light of which emerges from the underside of the lamp body 16 through a satin-faced plastic tray 18 which serves as a diffuser. The terms "ring" or "loop" should be used synonymously, whereby a lighting effect may be produced by individual LEDs and corresponding curved linear LEDs arranged at a predetermined angular distance.

In fig. 3b, individual LEDs 44 are schematically shown arranged in a ring or loop, in this example consisting of 16 LEDs, whereby the number of LEDs and the angular spacing can of course vary over a wide range. The ring or collar radius is selected such that in a commercially available bottle, the lighting element 20 does not protrude or does not protrude significantly beyond the bottle body. For example, an elongated wine bottle typically has a radius of about 3cm, so that the neck and shoulder structure can be optimally illuminated at a location of about 3cm (and possibly 3.5 cm).

A variety of other arrangements are conceivable in addition to those shown. For example, multiple LED rings may be provided, LEDs may be shining directly down on the board without a diffuser, etc., and additional lighting elements may also be provided that may diffuse the radiation up or illuminate the screen surface, although in an exemplary embodiment, the screen is opaque on the sides and top except for the backlight sensor switch.

In the LED ring and in the area surrounding the LEDs, curved reflector elements 42 are provided in the interior 24 of the lamp 10 in order to optimize the light distribution and light output. In an exemplary embodiment, the reflector element 42 is made as an integral rotator of reflective metal (e.g., aluminum) that extends generally from the outer edge of the screen or diffuser 18 to a radial starting point at the beginning of the rod element 28 and directs light substantially uniformly downward, with the light also being purposely directed onto an area along the rod element 28, particularly to illuminate the bottleneck area 40.

The diffuser plate 18 is offset in the umbrella-like lamp body 16 by a distance d in an upward direction (e.g. by about 1 to 2cm upwards), i.e. the edge of the lamp body 16 that remains below prevents the lighting elements from being seen directly, thus preventing glare effects.

As can be seen in the exemplary embodiment, the illumination element 20 is positioned slightly above the base of the rod-like element 28 (which coincides with the diffuser plate).

It is also conceivable within the scope of the invention to bring the lighting element 20 to a lower position using a suitable support structure (not shown) protruding from the lower edge of the lamp body. However, it is within the scope of the invention that the lighting elements (or at least not all lighting elements if a plurality of lighting elements are provided) should not be arranged deeper than the front end of the rod-like element 28 facing away from the lamp body 16.

As indicated by the arrows in fig. 1, the substantially downwardly radiated light is reflected or redirected through the bottleneck or curved region of the shoulder of the bottle, thereby creating an interesting lighting effect.

The LEDs in the LED ring 20 are preferably warm-tone or warm-white LEDs or LEDs that can be switched between these modes. Color or color tunable RGB or RGBW LEDs are also possible.

A battery, schematically indicated at 34, is also integrated into the lamp body 16, which battery can be charged via a cable connection (not shown) and charging and control electronics (not shown) via a USB charging port 26 on the underside of the lamp body 16 (e.g. according to the USB-C or Micro-USB standard), although other connection types may also be utilized, such as a connection for plug or induction charging.

The charging connection 26 is integrated into the diffuser plate and is preferably provided with a tie-down protection cap. Integrating the charging connection 26 into the diffuser plate (pointing downwards in the use position and thus protected) simplifies the splash protection, so that the lamp according to the invention (with a sufficiently sealed switch on top and a tight housing in other respects) is also substantially suitable for outdoor use (at least against dripping water). In particular, the housing may be protected according to IP 44.

The charging connection 26 in the lamp 10 according to the invention is particularly easy and convenient to access, since the lamp 10 can be removed and turned very easily from the object serving as a base, in particular from the bottle 12 serving as a base. The charging process may be signaled by a colored LED (not shown) integrated behind the diffuser plate 18, e.g. red LED = charging in progress, green LED = charging completed.

The lighting element may be turned on and off by a push button switch 22, the push button switch 22 being centrally located on top of the lamp body 16 and optionally adjustable in brightness via an electronic dimmer circuit by long press and hold. The push-button switch 22 is preferably designed as a sensor button and is preferably designed such that the lamp is not accidentally turned on even if the lamp is turned upside down, wherein the switch area is located on the support surface. The button of the switch 22 may be made opaque so that it will light up when the lighting element within the lamp body is activated.

When the battery is fully charged, the illumination duration is typically multiple hours. In the exemplary embodiment, the lamp body 16 (except for the diffuser plate 18) is designed to be opaque, i.e., there is no "glow" typical of lamp covers, but it is possible by appropriate choice of materials; furthermore, additional interior lighting elements (possibly having a different color than the downwardly directed lighting element) may be implemented if necessary.

It is also conceivable that one or more additional illumination means, for example one or more LEDs, may also be provided on the underside or edge of the rod-shaped element 28.

A special feature of the lamp 10 according to the invention is that it can be fixed to the neck of a standard open bottle 12 by means of a rod-shaped element 28 having a "handle".

For this purpose, the conically tapered rod element 28 is essentially composed of a rubber-like material 36, in the exemplary embodiment a silicone elastomer, which rubber-like material 36 is applied or attached to a harder plastic core (not shown), or has a central recess 30 and secures the lamp 10 in a bottleneck having a variable diameter (within certain limits).

For fixing the lamp body 16, a positive or frictional connection of the rod-shaped element in the neck 14 by means of a rubber-elastic material is desirable, but not absolutely necessary.

For bottles 12 having a neck diameter greater than the largest diameter of the rod member 28, it is generally sufficient if the rod member 28 is "loosely" inserted into the neck. The lower end surface of the lamp body 16 (typically the diffuser plate 18) then rests on the edge of the bottleneck 14 and holds the lamp body 16 in a straight, upright position. This is the lowest position of the lamp according to the invention with respect to the bottle mouth. For narrower bottlenecks, the actual height is determined by the possible insertion depth of the rod-like element 28.

Since said lower end surface of the lamp body (diffuser) 18 conveniently protrudes outside through the edge of the lamp cap (width d) to avoid direct viewing of the diffuser plate and thus of the light source (glare protection), the edge of the lamp cap may protrude slightly beyond the uppermost port portion of the bottleneck in the lowest position, i.e. in case of a wide bottleneck and a bottleneck almost directly against the diffuser plate.

In fig. 4, a preferred variant of the rod-shaped element 28 with the recess 30 is schematically shown in a sectional view. The recess 30 causes the remaining tubular elastic material 36 to be compressed, as indicated by the arrow in fig. 4, whereby the rod-like element 28 can be held particularly well in a friction manner. Furthermore, the rod-shaped element 28 can adapt to non-circular mouth cross-sections to the extent possible, even to seal bottles. The recess 30 does not extend to the bottom of the rod-like element 28 but merges into a recess 38 having a smaller cross section to accommodate a fastening screw (not shown) which can be screwed into a threaded counterpart in the lamp body and which can be accessed through the recess 30 so that an alternative fastening, for example a conventional rod (not shown) with a base, or a screw plug-like connecting element (also not shown) can be screwed on relatively easily. For temporary fastening, such an alternative connecting element can also be simply inserted into the recess 30 with the rod-shaped element.

The recess 30 is preferably circular but may also have a different profile, for example a polygonal profile.

The rod-like element 28 is secured to the lamp by means of screws (not shown) sunk into the bottom of the recess 30, the recess 30 preferably not extending over the entire length of the rod-like element, so that the rubber-elastic material 36 of the bottom of the recess provides a counter-bearing for the screws. Thus, the screw may be easily accessed through the recess 30, for example for maintenance purposes.

If desired, electrical contacts may also be provided on the rod-shaped element 28 to enable more convenient charging in a special charging station, which may also be used as an alternative lamp holder (not shown).

The lamp 10 according to the invention achieves particularly advantageous and glare-free illumination, for example when used with glass bottles, for example on dining tables, because the predominantly downwardly directed light from the lamp body 16 is reflected partly by the bottleneck region 40 or the bottle shoulder 32, thereby illuminating the surroundings without undesired glare effects.

Typical dimensions (each approximate dimension) of an exemplary embodiment of a lamp according to the present invention are:

this size example may of course vary in many ways, but is suitable for solving various common bottleneck problems.

From a design point of view, in particular the upper region of the screen can be designed in various modified ways, while on the other hand, dimensions such as the general lower lamp envelope diameter, the radius of the LED ring and the rod-like element preferably remain essentially as above, since these dimensions are tailored to the dimensions of a normal bottle. Possible deviations of the above-mentioned dimensions for the bottle may be, for example, ±10%.

For example, from a design perspective, the screen may have a polygonal profile, such as a rectangle with rounded corners, or a curved outer profile, which may be used to create a design appearance similar to a lamp shade with folds. Other design variants may include, for example, a pure cylindrical shape of the umbrella, i.e. not tapering upwards, a conical shape from this profile may also be combined with one or more cylindrical parts, such as a conical shape at the top and a cylindrical end ring at the bottom. Furthermore, the housing curve across the outside of the screen may also be curved, i.e. the screen may be designed in a bell-shaped or hemispherical or elliptical manner, for example.

In this example, the rod-like element 28 has a total length corresponding to about 45% of the total height of the chimney, whereby the protrusion of the chimney edge (16 mm in this example) relative to the diffuser plate 18 results in the rod-like element 28 (based on the diffuser plate 18) protruding only about 25mm (41 mm-16 mm) beyond the edge of the umbrella in total.

For very wide bottlenecks with a diameter larger than the largest diameter of the rod-like element 28, the lamp body is located on the bottleneck with its lower horizontal end, diffuser or stop flange arranged at the bottom of the rod-like element. In this case the bottleneck is covered partly by the protrusion d, but only to a small extent (in this example, about 16 mm). Essentially, the bottleneck remains free, especially if it is narrower and the rod-like element 28 is located higher.
