Definitions
- the invention relates to a lamp, in particular a table lamp, with an umbrella-like lamp body, the lamp having at least one lamp integrated in the lamp body, which emits light in at least one downward direction when in use.
- the object of the invention is to create a lamp of the type mentioned at the outset that combines high-quality, glare-free table or panel lighting with an interesting and varied design, and at the same time demonstrates a visible and original contribution to material recycling.
- the lamp body has a stem-like element on its underside, which is designed to fix the lamp in the neck opening of a commercially available bottle.
- the lamp can be used using almost any (unclosed) bottle - as long as the diameter of the bottle neck is compatible with the stem-like element - with the bottle then functionally serving as a kind of lamp base.
- simple glass bottles without a label can be used, but also champagne bottles, beer bottles, spirits bottles, Bockstüten or the like, each with a label or with a label that has been detached or was not present from the outset, each made of clear glass or colored glass.
- the lighting means has at least one ring or a ring of lighting elements, which is arranged around the stem-like element.
- the ring or ring can either be formed from individual lighting elements (in particular LEDs) with a predetermined angular spacing, it being possible to speak of a ring or ring from three LEDs with an angular spacing of approximately 120°; however, significantly more individual light-emitting elements are preferably provided.
- one or more linear LEDs can also be used.
- the invention provides that the lamp or at least one of the lamps is positioned in terms of its height above the stalk-like element or in the area of the approach of the stalk-like element to the lamp body or above the end of the stalk-like element facing away from the lamp body.
- the ring-shaped or ring-shaped light source (or at least one of the light sources, if several are provided) should therefore ultimately not be below the end face end of the rod-shaped element with regard to its height position - that is the positioning along an imaginary central axis that runs centrally through the rod-shaped element Elements are located, but preferably above the stem-shaped element or approximately at the level of the mounting lug of the stem-shaped element or slightly below.
- the arrangement of the lamps essentially above the stem-shaped element - and thus usually above the bottle opening - has the advantage that the lamp is at a height with standard bottle heights and standard table heights at which the lamps are on the underside are not directly visible even from a normal seated perspective (no glare), but an area-optimized illumination of the surroundings is nevertheless achieved.
- the bottle used itself including any labels on the bottle neck, is largely visible and even additionally illuminated, so that the invention is also advantageous for optically emphasizing the bottles themselves, e.g. for wine presentations or the like ., can be used.
- Existing structures on the bottle neck e.g. glass thread or the parts of a colored capsule film surrounding the bottle mouth, can be highlighted particularly effectively by the lighting.
- the light when the light is arranged according to the invention above the bottle opening, it is advantageous that the light is usually directed into the edge of the bottle neck.
- this feed-in at the front edge causes a light-guiding effect (transmission of the light through multiple total reflection), which leads to an internal glow of the bottle glass or any bottle contents and thus to an interesting optical effect.
- the stem-like element is conical on the outside at least in sections, preferably with a cone angle >4°, particularly preferably >5°.
- cone angles which are relatively high for stoppers, enable use in a wide range of bottleneck diameters, but tend to worsen the hold of the stem-like element in the bottleneck, so that further measures to improve frictional fixing should generally be provided.
- the stem-like element can be formed, at least on its outside, from a rubber-elastic material, preferably from a silicone elastomer be, wherein the stem-like element is particularly preferably formed substantially entirely from a silicone elastomer.
- the stem-like element can preferably have a recess open towards the free end thereof.
- the lamp body can also be attached alternatively without conversion, e.g. put on a suitable rod or post.
- the stalk-like element formed in this way thus allows fixation both by positively or loosely embracing the outer contour (such as when plugging into a bottleneck) and by positively or loosely engaging in the recess provided in the stalk-like element (e.g. by attaching it to a rod), ie by means of the inner contour of the stem-like element.
- Such a recess also improves the effect of a material elasticity of the stem-like element, since this can be compressed to a certain extent by the recess. Furthermore, access to a concealed fastening screw can be established via the recess.
- the recess can also not extend to the base of the stem-like element, but rather end further up or taper (if, for example, the recess merges into a considerably narrower through-hole for a fastening screw). This stabilizes the section of the stem-like element on the lamp body side that is not "hollowed out" by the recess, so that the deformation of the stem-like element can be limited or controlled.
- the stem-like element is conical on the outside, has a recess which is open towards the free end of the stem-like element and does not have to extend to the bottom of the stem-like element, and consists—at least in the region of the recess—of an elastic material.
- the stem-like element can be compressed by a predetermined amount when it is fixed in the neck opening of a commercially available bottle, so that reliable frictional fixing in a bottle neck opening and/or adaptation to non-round bottle neck openings can be achieved.
- a pre-tensioning force is automatically set up in the bottle neck, which ensures a very reliable frictional fixation in the bottle neck, which can also be easily released again.
- the stem-like element a temporary sealing of the bottle can be achieved, so that - assuming the material of the stem element is food safe, which is the case in a preferred embodiment - the lamp according to the invention can also be used as a temporary bottle closure, for example for the closure of carbonated drinks , can be used.
- the stem-like element is preferably dimensioned in such a way that an optimal hold is guaranteed in a large number of common bottleneck diameters, with the stem-like element preferably being designed to be significantly shorter than would typically be the case, for example, with a lamp base of a classic umbrella lamp, since the lamp base is is preferably formed by the bottle itself.
- the stem-like element can have one or more of the following dimensional or material properties - insofar as they are compatible: the length of the stem-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 stem-like element is between about 30 mm and about 50 mm; and/or the outside diameter of the stem-like element-possibly tapering conically towards the free end-is between approx. 10 mm and approx.
- the outer diameter of the stem-like element tapers from a diameter on the lamp body of between 19 mm and 22 mm to a diameter at the free end of between 15 mm and 18 mm; and or the stem-like element has a central, longitudinally extending, open towards the free end recess with a diameter between 5 mm and 12 mm; and/or the stem-like element has a central, longitudinally extending recess which is open towards the free end and extends over only about 30% to 60% of the length of the stem-like element; and/or the stick-like element is made of food-safe materials.
- the at least one light source integrated into the lamp body has a ring or ring, each formed from at least three, preferably more than three, individual light-emitting diodes distributed uniformly over the circumference and/or formed from at least one linear LED. with the main emission direction of the LEDs pointing downwards.
- At least one of the illuminants formed from ring-shaped or ring-shaped lighting elements has a ring or ring radius of ⁇ approx. 3.5 cm, so that its ring or ring radius is smaller or not significantly higher than the radius of conventional bottles , in particular wine bottles, and it is thus ensured that the illuminant can illuminate the neck and shoulder structures of the bottle.
- Typical narrow wine bottles (0.75 l) have a radius of at least approx. 3 cm (diameter approx. 6 cm). Therefore, with a specified tolerance, the above-mentioned dimension results, with a particularly suitable radius for the lamp ring being around 3 cm.
- the lamp according to the invention thus has a different lighting effect than a conventional, otherwise comparably dimensioned table lamp, which is simply arranged on a rod.
- a battery element or a rechargeable battery element can be integrated into the lamp body, by means of which the at least one illuminant can be supplied with power in a wireless manner.
- the umbrella-like lamp body can be made of a non-transparent material, so that the lamp essentially only emits light downwards.
- this is different from a classic table lampshade (e.g. made of colored glass), which is often partially transparent and still lets a little light from the lamp through in the form of a "glow".
- a classic table lampshade e.g. made of colored glass
- the latter i.e. a transparent or partially transparent design of the side surfaces of the lamp body - is also conceivable according to the invention.
- the basic shape of the lamp body does not necessarily have to be circular, but it can also be elliptical or based on a polygon.
- the umbrella-like lamp body is preferably round in top and bottom view, with at least one button-like or contactless switching element for switching the at least one light source on/off and optionally for adjusting the brightness and/or light color being provided on its top. If necessary, the switching element can also be attached elsewhere (e.g. inconspicuously on the underside of the lamp body).
- the lamp is particularly preferably splash-proof and/or protected against the ingress of foreign bodies, so that outdoor use is possible without any problems.
- the lamp can be designed according to protection class IP44 (corresponding to the usual protection class for damp rooms), which in a preferred embodiment can be implemented with manageable structural effort due to the relatively few construction-related joints that have to be sealed.
- differentiated and central lighting control by remote control via ISM band radio receiver or e.g. WLAN, Bluetooth
- ISM band radio receiver via ISM band radio receiver or e.g. WLAN, Bluetooth
- Such differentiated control options are of particular interest if the light color can also be adjusted using RGB or RGBW light-emitting diodes. Automatic switching on/off or brightness adjustment based on the signal from an ambient light sensor is also conceivable.
- loudspeakers into the lampshade, preferably on the underside in the area not required by the light-emitting diodes, which can be addressed via audio streaming (WLAN/Bluetooth or the like) from the integrated energy store be supplied and thus a sound reinforcement of a dinner party - if necessary also with surround sound through the use of several loudspeaker lights - enable.
- audio streaming WLAN/Bluetooth or the like
- a bass reflex opening could also be provided on the top of the lamp body to improve the sound.
- a lamp arrangement (or a "set") which has a lamp (the lamp body) of the above described type and contains a suitable bottle as a lamp holder, in the bottle neck, the lamp can be fixed with the stem-like element.
- This "set” eliminates the need for the user to source or select a matching bottle, although the user can always use “own” bottles if they wish.
- the set can contain a base with a support rod that is matched to the recess in the stalk-like element, with a stationary drawer possibly having contacts at the end of the support rod that come into contact with suitable contacts inside the stalk-like element - And/or the operating voltage can be supplied to the lamp via the support rod, for which purpose the support rod is then typically supplied with a low-voltage power supply unit or its own rechargeable batteries via a foot.
- inductive charging can also be enabled via appropriate coupling coils incorporated into the lampshade.
- the present invention is also suitable, for example, for emphasizing certain drinks (wines or the like) offered at an event by presenting the corresponding bottles in an original way.
- a lamp according to the invention can also be used “pure”, i.e. without the bottle as a stand, for other lighting purposes, for example by turning the lampshade “upside down” as an “uplight” for temporary effect lighting of objects or signs from below or from the side, or by placing it on the outer surface of the shade so that the light shines upwards like a small spotlight and can thus illuminate certain objects in a targeted manner.
- the stem-like element can thus fulfill several functions at the same time in the light according to the invention:
- the stem-like element described above can, if it can be easily connected to and separated from the lamp body by a user - e.g. via a threaded connection, a clip or a bayonet catch - if necessary also as a separate optional accessory for fixing a lamp body in the neck a commercially available bottle are offered as part.
- the stem-like element can preferably have the features described above, in particular manufacture as a conical hollow cylinder from a preferably food-safe silicone elastomer with an overall length that is shorter than the height of the lampshade.
- a corresponding lamp body prefferably with a base
- the support rod being detachably fixed in a rod-like element on the light side within the meaning of the invention, so that the light can be easily fixed by the user in a commercially available bottle could be converted.
- an alternative connecting element that can be connected to a screen-like lamp body of a lamp instead of the above-described stem-like element (e.g. by means of a screw connection) is proposed.
- the alternative connecting element is suitable for fixing the lamp body in the neck opening of a commercially available bottle closed with a (natural or artificial) cork by having a screw spindle in the manner of a corkscrew, which can be screwed a few turns into the material of the cork for fastening until a sufficient hold is reached.
- FIG. 1 shows an overall sectional view of a lamp according to the invention with a transparent water bottle as the lamp base;
- FIG. 2 shows a schematic representation of the lamp according to FIG. 1 in a position removed from the bottle;
- FIGS. 3a, b show schematic bottom views of the lamp according to the invention from FIG. 2; and
- FIG. 4 shows a schematic sectional view of a stem-like element with a recess.
- a lamp labeled 10 overall (ignoring the bottle 12 serving as a holder) has a typical conical lampshade shape in the exemplary embodiment, although as mentioned other shapes (cylindrical, polygonal basic shapes, hemispherical shape, etc.) would also be possible.
- bottles used will often be empty. However, it is also possible--if the handle element is designed appropriately for use with food--to close a completely or partially filled bottle with the lampshade. If necessary, the bottle can be filled with at least water or a colored 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.
- the lamp 10 has a lamp body 16, in whose inner space 24 in the outer or central area a circumferential LED ring or LED ring is provided as a light source 20 (shown schematically), the light coming from the underside of the lamp body 16 through a satin plastic disc 18, which serves as a diffuser, exits.
- a light source 20 shown schematically
- the terms “ring” and “wreath” should be used synonymously, with the lighting effect being able to be formed both by individual LEDs arranged at predetermined angular distances and by correspondingly curved linear LEDs.
- the ring-shaped or ring-shaped arranged individual LEDs 44 in the example 16 pieces—are indicated schematically, with the number and angular spacing of the LEDs obviously being able to vary within a wide range.
- the radius of the ring or rim is selected in such a way that, in the case of commercially available bottles, the illuminant 20 does not protrude or does not protrude significantly beyond the body of the bottle.
- Slim wine bottles typically have a radius of about 3 cm, for example, so that the bottle neck and bottle shoulder structures can be optimally illuminated with a positioning at about 3 cm (possibly also 3.5 cm).
- many other arrangements are conceivable.
- several LED rings can be provided, these can shine directly downwards on a plate without a diffuser, etc., and lamps can also be provided that shine diffusely upwards or illuminate the screen surfaces, although in the exemplary embodiment the screen - except for the backlit sensor switch - is opaque at the side and at the top.
- a curved reflector element 42 is provided in the interior 24 of the lamp 10 in order to optimize the light distribution and light yield.
- the reflector element 42 is designed as a one-piece rotating body made of reflective metal (e.g. aluminum), which extends approximately from the outer edge of the screen or diffuser 18 to the radial starting point of the stem-like element 28 and deflects the light essentially uniformly downwards , whereby the light is deliberately also directed onto the area along the stem-shaped element 28 in order to also illuminate the bottleneck area 40 in particular.
- reflective metal e.g. aluminum
- the diffuser plate 18 is offset upwards in the umbrella-like lamp body 16 by a distance d (e.g. by approx. 1 to 2 cm), i.e. the remaining edge of the lamp body 16 underneath prevents direct visibility of the lamps and thus glare effects.
- the lighting means 20 is positioned somewhat above the base of the stem-shaped element 28 (which coincides with the diffuser plate).
- the lighting means 20 it would also be conceivable within the scope of the invention to bring the lighting means 20 to a lower position by means of suitable support structures (not shown) protruding from the lower edge of the lamp body.
- suitable support structures not shown
- the lighting means (or at least not all lighting means, if several are provided) should not be arranged lower than the front end of the rod-shaped element 28 facing away from the lamp body 16 .
- the light radiating essentially downward through the curved areas of the bottle neck or the Reflected or deflected by the shoulder of the bottle, which creates interesting lighting effects.
- the LEDs of the LED ring 20 are preferably warm tone or warm white LEDs or LEDs that can be switched between these modes. However, colored or color-adjustable RGB or RGBW LEDs are also possible.
- a rechargeable battery is also integrated into the lamp body 16, which can be charged via cable connections (not shown) and charging and control electronics (not shown) via a USB charging connection 26 (e.g. according to the USB-C or micro-USB standard) on the underside of the lamp body 16, although other types of connection, such as a connection for a jack plug or inductive charging, can also be used.
- a USB charging connection 26 e.g. according to the USB-C or micro-USB standard
- other types of connection such as a connection for a jack plug or inductive charging, can also be used.
- the charging connection 26 is integrated into the diffuser plate and is preferably provided with a captive protective cap.
- the housing can be protected according to IP44.
- the charging connection 26 in the lamp 10 according to the invention is particularly easy and convenient to access.
- the lamps can be switched on and off via a pushbutton switch 22, which is positioned centrally in the upper side of the lamp body 16, and the brightness can optionally be adjusted via an electronic dimmer circuit by pressing it for a long time.
- the switch 22 is preferably in the form of a sensor button and is preferably designed in such a way that even when the lamp is turned upside down, in which the switch area is used on a support surface, no the lamp is accidentally switched on.
- the button of the switch 22 can be made opaque, so that it also lights up when the lighting means inside the lamp body are activated.
- the lighting duration is typically several hours.
- the lamp body 16 - apart from the diffuser plate 18 - is designed to be opaque, i.e. the usual "glow" of a lampshade is not given here, but would be possible through the appropriate choice of material and, if necessary, additional internal lamps (possibly in different colors than the lamps pointing downwards) can also be implemented.
- one or more additional lighting means e.g. one or more LEDs, could also be provided on the underside or on the edge of the rod-shaped element 28 .
- the lamp 10 according to the invention can be fixed in the neck of a commercially available open bottle 12 with a “handle” via a stem-shaped element 28 .
- the stem-shaped, tapering stem-shaped element 28 essentially consists of a rubber-like material 36, in the exemplary embodiment a silicone elastomer, which is either applied or attached to a harder plastic core (not shown), or which has a central recess 30 and holds the lamp 10 in bottlenecks with a diameter that is variable within limits.
- the stem-like element 28 In the case of bottles 12 with a larger neck diameter than the maximum diameter of the stem-like element 28, it is usually sufficient if the stem-like element 28 is "loosely" inserted into the bottle neck. Then the lower end surface of the lampshade 16 (usually the diffuser plate 18) rests on the rim of the bottle neck 14 and holds the lampshade 16 in a straight, upright position. This is the lowest position of the lamp according to the invention in relation to the bottle opening. With narrower bottlenecks, the actual height results from the possible insertion depth of the stick-like element 28.
- the aforementioned lower end surface of the lampshade (the diffuser) 18 is expediently protruded from the outside by an edge of the lampshade (width d) in order to prevent the diffuser plate and thus the light source from being directly visible (anti-glare protection), the lowest position ( ie when the bottle neck is wide and the mouth of the bottle rests almost directly on the diffuser plate), the edge of the lampshade protrudes slightly over the uppermost mouth section of the bottle neck.
- a preferred variant of the stem-like element 28 with the recess 30 is shown schematically in section in FIG.
- the recess 30 causes the remaining tubular elastic material 36 - as indicated by the arrows in Figure 4 - can be compressed, whereby the stem-like element 28 can be held particularly well frictionally. Furthermore, as a result, the stem-like element 28 can, within limits, adapt to non-round bottle opening cross-sections and even seal the bottle.
- the recess 30 does not go to the bottom of the stem-like element 28, but merges into a recess 38 with a smaller cross-section for receiving a fastening screw (not shown), which can be screwed into a threaded counterpart in the lamp body and which is accessible via the recess 30 So that relatively easily an alternative attachment - such as a conventional rod with a base (not shown) - or a corkscrew-like connecting element, also not shown, can be screwed tight. For a temporary attachment, however, such alternative connecting elements can also simply be inserted into the recess 30 when the stem-like element is present.
- the recess 30 is preferably round, but can also have a different contour, for example a polygonal contour.
- the stem-like element 28 is fixed to the lamp by means of a screw (not shown) countersunk in the bottom of the recess 30, the recess 30 preferably not extending over the entire length of the stem-like element, so that the rubber-elastic material 36 at the bottom of the recess provides a counter bearing for the screw.
- the screw is thus easily accessible via the recess 30, for example for repair purposes.
- electrical contacts can also be provided on the rod-shaped element 28 in order to enable more convenient charging in special charging stations that can also serve as an alternative lamp base (not shown).
- the lamp 10 according to the invention achieves a particularly favorable and glare-free lighting, especially when used with glass bottles, for example for use on restaurant tables, since the light of the lamp body 16 primarily radiating downwards is partially reflected by the bottle neck area 40 or the bottle shoulder 32 and so without undesired glare illuminates the surroundings.
- Typical dimensions of an exemplary embodiment of a lamp according to the invention are (approximate dimensions in each case):
- This dimensioning example which can of course be deviated from in many ways, is suitable for fixing to a wide variety of common bottlenecks.
- the upper area of the screen in particular can be modified in many ways, while on the other hand Sizes such as the approximate lower screen diameter, the radius of the LED ring and the dimensions of the stem-like element are preferably retained essentially as above, since these sizes are matched to the dimensions of common bottles. Possible deviations from the above-mentioned sizes adapted to the bottle can be, for example, ⁇ 10%.
- the shade could have a polygonal contour, e.g. rectangular with rounded corners, or a curved outer contour, by means of which a design impression based on lampshades with pleats can be created.
- Another possible design variant would be, for example, a purely cylindrical shape for the screen, i.e. not tapering upwards, whereby a conical shape of the outer contour can also be combined with one or more cylindrical sections, e.g. a conical shape at the top and a cylindrical end ring at the bottom.
- the envelope curve spanning the outside of the screen could also be curved, i.e. the screen could be designed, for example, in the shape of a bell or hemispherical or ellipsoidal.
- the rod-like element 28 has an overall length that corresponds to about 45% of the total height of the lampshade, with the overhang of the edge of the shade in relation to the diffuser plate 18 - in the example of 16 mm - from which the rod-like element 28 emanates rod-like element 28 protrudes a total of only about 25 mm (41 mm - 16 mm) over the edge of the screen.
- the lamp body sits on the bottleneck with its lower horizontal end, the diffuser, or with a stop flange provided at the base of the stem-like element.
- the bottle neck is partially covered by the overhang d, but only to a small extent (approx. 16 mm in the example). Essentially, the neck of the bottle remains free, especially when it is narrower and the stem-like element 28 is higher.
