Definitions
- the invention relates to a lamp with an adjustable inclination.
- Lamps are known from the prior art, in particular floor lamps, in which an upper part of the lamp can be adjusted in inclination relative to a lower part of the lamp by a joint connection between the two.
- the object of the invention is to provide a lamp whose adjustability with regard to inclination offers a greater degree of freedom.
- a lamp with adjustable inclination which has a housing with a convex base section and a screen section connected thereto and a weight that is fixed in the base section so that its position can be changed in such a way that a center of gravity of the Luminaire is variable, includes.
- a light source can be arranged in the housing, which is set up to emit light at least through the shield section.
- the inclination of the lamp is adjustable by changing a position of the weight within the foot section.
- the lamp according to the invention thus allows a change in the position of the center of gravity and thus in the static rest position of the lamp. Accordingly, by changing the position of the weight, a change in the static rest position of the lamp is possible, which, due to the convex shape of the foot section, leads to the lamp tilting according to the changed position of the center of mass, whereby the lamp assumes a new static rest position with a corresponding inclination of the lamp . Accordingly, the inclination of the lamp can be adjusted by changing the position of the weight, limited by reaching an unstable or unstable position.
- Such a light is not known from the prior art, in which only a part of the light, for example a light upper part, can be changed in relation to another part of the light, for example a light lower part in its inclination.
- a change in the inclination of the light - and thus the light as a whole - is not possible with the lights from the prior art.
- well-known lamp only allow adjustment of the inclination of a part of the luminaire and not of the luminaire as such.
- the shade section can have essentially any shape, as a result of which the luminaire can be designed in a particularly diverse manner.
- the shield section can preferably be designed to be translucent or partially transparent up to and including fully transparent in order to enable light to be emitted through the shield section.
- the screen section can also be made of an opaque material, which allows light to be emitted through recesses such as perforations.
- the screen section can preferably consist of a plastic such as resin, in particular polycarbonate, which can, for example, be diffusely refractive.
- the screen section can also consist of glass, ceramics and the like.
- the screen section can be produced particularly advantageously by injection molding.
- foot section which can also be designed to be translucent or partially transparent up to and including fully transparent or opaque.
- the upper and lower parts are preferably made of the same material and are translucent.
- all suitable light sources can be considered as light sources, such as LED light sources including flat lights and/or retrofit lights, fluorescent tubes, conventional light bulbs and the like.
- the illuminant can be supplied with electricity by means of a power cable routed out of the lamp and/or have a rechargeable battery in order to be operated (at least temporarily) without an external power supply.
- the lighting means can also be provided with control electronics in order to be controlled by a remote control means. This includes both dedicated hardware devices (remote control in the narrower sense) and multifunction devices equipped with the appropriate software, such as computers, smartphones, tablets and the like.
- a control interface such as a touchscreen and buttons on the lamp itself or, if present, on the power cable can also be provided.
- the parameters of the light output of the lamp as desired.
- the use of an illuminant provided with RGB light-emitting diodes is possible.
- the term “convex” is interpreted broadly and refers to all surfaces that are curved outwards (related to the foot section). The surface does not necessarily have to be rotationally symmetrical.
- the degree of positional variability of the weight in such a way that at a maximum positional change the lamp does not (barely) assume an unstable or unstable position, so that the lamp can be prevented from tipping over.
- This can be achieved by appropriate static design of the center of mass of the luminaire and taking into account the mass of the weight by calculation or by experimental analysis.
- the base section of the lamp In order to increase the stability of the lamp, it is also preferred to place the base section of the lamp on a retaining ring resting on the actual installation site.
- This can be made of transparent silicone, for example.
- Retaining rings made of wood, ceramic or metal or other materials are also suitable.
- a weight that is variable in position according to this embodiment is particularly easy to handle, because changing the position only requires rotating the spindle about its spindle axis, as a result of which the weight can be displaced along the spindle axis according to the pitch of the spindle. Essentially, only a transverse force acts on the spindle, which means that the spindle and bearing points are subject to low stress.
- an adjustment range is defined in the direction of the longitudinal extent of the spindle, within which the weight is slidably attached to the spindle and that the adjustment range is shorter than a distance between the bearing points.
- the position of the weight can only be changed in the predetermined setting range.
- the maximum inclination of the lamp can be limited, preferably in order to allow only statically stable positions of the lamp.
- the lamp comprises a base weight arranged in a lower part of the base section and rigidly connected thereto, which is set up to change a position of the center of mass of the lamp in the direction of a longitudinal axis of the base section.
- the stability of the lamp in the tilted state can be increased by always ensuring a restoring torque.
- This is particularly advantageous for particularly high luminaires, which would cause an unfavorable shift in the center of mass of the luminaire, e.g. with particularly long upper parts.
- “In the direction of a longitudinal axis” means both along the direction of the longitudinal axis and from a position laterally next to the longitudinal axis further towards the longitudinal axis.
- a particularly dense material is preferred for the foot weight, such as a metal, to achieve high mass with low volume.
- a foot weight that can be provided in such a compact manner affects the light emission as little as possible.
- the foot weight can be designed, for example, in the shape of a cone or a truncated cone.
- the base weight can be provided with a (possibly diffuse) reflecting surface.
- the weight is particularly preferably designed as a power store, so that the lamp can be designed to be wireless.
- an inductive charging option is preferably provided, in which the corresponding conductor loop for transmitting electrical energy is arranged in the foot part and is connected to the power storage device via charging electronics.
- the shape is preferably similar to an inverted pyramid, truncated cone or cone, thereby providing benefits in terms of shadowing.
- the corresponding external charging device for generating the inductive energy transfer ideally has a concave area into which the base of the lamp can be placed in order to charge it.
- concave bearing points can also be integrated into pieces of furniture, for example, which then increases the friction at the same time and the lamp has an even more secure footing.
- the convex foot section is partially ellipsoidal, preferably semi-ellipsoidal and particularly preferably semi-spherical.
- the foot portion be convex. This includes a particularly high variety of shapes for the foot section.
- a hemispherical foot section is particularly preferred, since this is particularly easy to produce and is particularly aesthetically pleasing due to its rotationally symmetrical shape.
- the spindle extends parallel to a major axis or a minor axis of the part-ellipsoidal or semi-ellipsoidal base portion, particularly in the case of the hemispherical base portion parallel to a diameter of the hemispherical base portion.
- the umbrella section and the foot section are releasably connectable in a plurality of orientations relative to one another, the orientations differing in terms of an angle of rotation about an axis of rotation that extends through a center point of a base area of the umbrella section.
- the luminaire to be designed with a particularly high degree of freedom.
- a user can also change the outer shape of the lamp in as many ways as possible by changing the relative orientations of the shade section and the base section. This adjustability is particularly effective when using a non-rotationally symmetrical shield section.
- orientations about the axis of rotation are continuously selectable, or (ie alternatively) the orientations about the axis of rotation are discontinuously selectable and are preferably selectable at equally spaced angular differences from each other about the axis of rotation.
- the light can be configured so that the orientations are continuously selectable. If only certain orientations are to be made possible, the light can be configured in such a way that the orientations can only be selected discontinuously. The latter can be desired, for example, when a number of lights are to be used at one installation location and a uniform appearance is to be configurable.
- the shade section and the base section are each fastened to a connecting ring, in the inner area of which a receptacle for the illuminant is arranged.
- the connecting ring can have a corresponding mechanical interface which enables the ability to rotate.
- This can be, for example, an annular groove running around (at least partially) in the circumferential direction of the connecting ring, in which the shield section engages and in which it can be (detachably) fastened, for example by clamping or by screwing.
- the shield section at its end preferably engaging in the connecting ring with magnets (sunk in the shield section itself) which can interact with corresponding magnets of the connecting ring or with a magnetic ring groove of the connecting ring.
- the discontinuous selectability of the orientations can be achieved, for example, in that the screen section and the connecting ring or its annular groove can only be mechanically connected in predetermined orientations, for example by means of a tongue and groove pairing or by using a bayonet lock.
- the position of the lamp can be adjusted by changing the position of the weight using a drive device.
- the Drive device includes at least one motor that changes the position of the weight.
- the drive device can also include other auxiliary means, for example various belt drives which interact to change the position of the weight.
- a pendulum is provided in the base section of the lamp, which pendulum has an antenna which is provided for the transmission of energy for the inductive charging of an energy store.
- This pendulum preferably penetrates the base weight of the lamp, which in particular simultaneously forms the energy store, so that the antenna of the pendulum has the smallest possible distance from the antenna provided outside the lamp in order to enable efficient inductive charging.

- An LED retrofit lamp can also be provided instead of the flat lamp or in addition thereto.
- the inclination of the lamp 100 can be adjusted by changing a position of the weight 20 within the foot section 11, as shown in FIGS. 1a and 1b.
- the weight 20 is fastened to a spindle 40 which is mounted in the foot section 11 at bearing points 41 such that it can be rotated about a spindle axis (S) so that it can be displaced.
- a longitudinal extension of the spiral of the spindle 40 defines an adjustment range, within which the weight 20 is slidably mounted along the spindle 40, and that the adjustment range is shorter than a distance between the bearing points 41.
- the spiral of the spindle 40 can be connected at its ends to a shaft which carries the spiral.
- the spindle 40 is held by the shaft, which is rotatably mounted in the foot section 11 at the bearing points.
- the weight 20 can preferably have a closed eyelet which runs on the spiral, as a result of which the weight 20 can be attached to the spindle 40 in a captive and displaceable manner.
- Spindle 40 is operable by an outwardly protruding handle.
- the spindle 40 can also be actuated by a (remotely) controllable actuator such as a motor.
- the lamp 100 preferably comprises a base weight 50 arranged in a lower part of the base section 11 and rigidly connected thereto.
- the base weight 50 can be set up to position the center of mass of the lamp 100 in the direction of a longitudinal axis (L) of the foot section 11 affect, especially in all positions for a righting torque.
- the convex foot section 11 can be partially ellipsoidal, preferably semi-ellipsoidal and particularly preferably semi-spherical.
- the spindle 40 can extend parallel to a main axis or a secondary axis of the partially ellipsoidal or semi-ellipsoidal foot section 11, in particular in the case of the hemispherical foot section 11 parallel to a diameter of the hemispherical Foot section 11 can extend. In the example, this is achieved by arranging the spindle 40 horizontally in relation to the neutral inclination 100 of the foot section 11 in FIG.
- the umbrella section 12 and the foot section 11 can be releasably connected in several orientations, with the orientations in terms of an angle of rotation about an axis of rotation (D) passing through a Center of a base of the shield portion 12 extends, differ.
- the umbrella section 12 can be detachable from the base section 11, as shown, and can thus be reconnected to the base section 11 in a different orientation.
- the lamp 100 can thus be designed in a particularly variable manner.
- the orientations about the axis of rotation (D) can be selected continuously or discontinuously and can preferably be selected in angular differences about the axis of rotation (D) that are uniformly spaced apart from one another.
- the shade section 12 and the foot section 11 are preferably each attached to a connecting ring 60, in the interior of which a receptacle for the illuminant 30 can be arranged.
- An example of the connecting ring 60 can be seen particularly well in FIG.
- a T-shaped projection can be arranged protruding from the cylinder wall, which can thus form two annular grooves in which the shield section 12 and the foot section 11 can engage (preferably releasably) in order to be connected to one another.
- the shield section 12 and the foot section 11 can each be fastened to the connecting ring 60 in a variety of ways, for example by means of a bayonet catch.
- the connecting ring 60 is made of aluminum.
- the recording of the light source 30 can be based on the formation of a connecting ring 6o inwardly directed projection, which preferably also allows light emission of the illuminant 30 through the foot section 11,
- a manual operation in which, using an externally accessible element, the spindle 40 is rotated inside the base section 11, thereby linearly changing the suspension point of the weight 20.
- the weight 20 in order to change the position of the weight 20, a manual operation is provided in which, using an externally accessible element, the spindle 40 is rotated inside the base section 11, thereby linearly changing the suspension point of the weight 20.
- a drive device for example an electric motor.
- an aluminum profile 90 is arranged in the foot section 11 and is locked at its two opposite ends in the longitudinal direction by a first holder 91 and a second holder 92 on the foot section 11 .
- the two holders 91 and 92 can be fastened to the connecting ring 60 on opposite sides, for example.
- the two brackets 91 and 92 hold the aluminum profile 90, which at the same time defines the direction of movement of the weight 20 with its length.
- a shaft or axle 93 or 94 is arranged on the holders 91 and 92 and carries a drive wheel 95 or a driven wheel 96, respectively.
- a revolving endless belt 97 is arranged on the drive wheel 95 and the driven wheel 96 .
- This endless belt 97 is driven using a motor 70 as the driving device, the control of the motor 70 (not shown in the figure) being designed in such a way that the endless belt 97 can be moved both clockwise and counterclockwise with respect to the representation of the figure .
- choosing an aluminum profile has 90 technical advantages.
- another connection between the two mounts is also conceivable, which has a linear extension and is suitable for fastening the motor 70 and the pendulum, which will be explained below, and for forming a rail for the weight 20 .
- a manual actuation can also be provided in the second embodiment, which can be operated by means of an actuation element 80 protruding outwards from the foot section 11 .
- This actuating element 80 interacts with a bevel gear 81, which is in engagement with a further bevel gear, not shown in the figure, which is fixedly connected to the drive wheel 95.
- the additional bevel gear, not shown serves at the same time as a belt pulley in order to interact with the motor 70 via an additional drive belt.
- a rotation is thus effected in a clockwise or counter-clockwise direction.
- the driven pulley of the motor 70 is described below with reference to FIG.
- the weight 20 is firmly connected to the endless belt 97 so that it follows a movement of the endless belt 97 . As shown in FIG. 5, this allows the weight 20 to be shifted in the direction indicated by the double-sided arrow.
- the position of the weight 20 is thus changed by the motor 70 as the drive device in such a way that the entire center of gravity of the lamp or of the foot section 11 can be adjusted.
- the motor 70 is preferably controlled by a controller that can be operated remotely by an external control device (for example a smartphone on which an app is installed).
- the base weight 50 can simultaneously serve as an energy store for powering the lamp 100 .
- the power supply for the motor 70 also comes from the base weight 50 .
- an inductive charging device 85 is provided for recharging the energy store.
- the inductive charging device 85 preferably also serves as the basis for the lamp 100.
- the part of the housing of the charging device 85 facing the lamp 100 preferably has a concave central area on which the convex foot section 11 can be positioned.
- the actual charging electronics 87 are arranged inside the housing of the charging device 85 and are connected to a first antenna 86 for wireless transmission of energy to the lamp 100 .
- This first antenna 86 is arranged in the middle, concave area of the charging device 85 .
- the first antenna 86 interacts with a second antenna 76 which is arranged inside the foot section 11 .
- the charging technology itself is known from various areas, for example the induction charging of mobile phones, tablets, electrical hand tools or similar devices and can be adapted to the desired or required energy requirements of the light and the drive technology.
- the second antenna 76 is fixed in place in the foot section 11, it is preferred if the second antenna 76 moves as a function of the inclination of the foot section 11 in such a way that it is independent of the set inclination of the lamp 100 of the first antenna 86 opposite. According to the preferred embodiment, this is achieved in that the second antenna 76 in the foot section 11 is part of a pendulum 75 that is so is suspended that the second antenna 76 is always at the lowest point of the foot section 11 due to gravity and thus at a small distance from the first antenna 75 when the lamp 100 is parked on the charger. Due to the wireless energy supply, the operation, including the motorized position change, free positioning of the lamp 100 is possible when the energy store is sufficiently charged. Control of the center of gravity with the adjustable position of the weight, together with the dome-shaped foot section, means that the lamp returns to the desired position, even if it has been thrown out of position, for example by accidental knocking.
- the pendulum 75 is formed in the base portion 11 with one end of the pendulum 75 being formed by the second antenna 76 .
- the pendulum 75 is rotatably but fixedly suspended at its end facing away from the second antenna 76 .
- the axis of rotation is perpendicular to the direction of movement of the weight 20.
- the pendulum 75 is constructed so as not to impede the movement of the weight 20 so as not to limit the maximum adjustment of the tilt of the luminaire 100. This is also explained below with reference to FIGS. 7 and 8.
- the weight 20 can be moved in both directions along the aluminum profile 90 starting from a central position which is in the geometric center of the longitudinal extension between the first bracket 91 and the second bracket 92 .
- a deflection of the base section 11 (and thus an inclination of the entire lamp 100) is thus possible in both directions.
- the longitudinal extent and the direction of movement, as well as the axis of rotation D already described above, lie in the plane of inclination, while the axis of the pendulum 75 runs perpendicular thereto. In the neutral position of the foot section 11, the axis of rotation D coincides with the vertical.
- the masses of the other components arranged in the foot section 11 are also balanced in such a way that the overall center of gravity coincides with a middle position of the weight 20 . Any asymmetry of the maximum inclinations of the entire luminaire 100 thus results only from the asymmetrical mass distribution of the shade section 12.
- FIG. 6 shows a second deflection of the foot section 11.
- the angle a' between the vertical and the axis of rotation D is larger than the angle a in the illustration in FIG.
- This is achieved by the weight 20 being deflected further in the direction of its one end position at the second holder 92 .
- this is done with the help of the motor 70 and a first belt drive, which acts on the drive wheel 95 Endless belt 97 moves so that the weight 20 coupled thereto is further displaced from its center position.
- the turning axis D is tilting further compared to the vertical one.
- a reverse direction of movement then straightens the lamp 100 up again, and if the weight 20 is shifted further, the lamp 100 inclines in the other direction.
- no specific bearing is provided between the foot section 11 and the loading device 85 .
- the lamp 100 or more precisely the base section 11, is placed directly on the housing in its concave area.
- it can also be provided, for example, to provide ball elements in the charging device 85 for mounting the lamp 100, which result in a reduction in friction for easier movement of the foot section 11 have. Effects such as oscillating by regularly reciprocating displacement of the weight 20 can thus be achieved without great expenditure of energy.
- the second antenna 76 which is attached to the pendulum 75, does not change its position in relation to the first antenna 86 of the charging device 85 due to the force of gravity. In this way, it is ensured that a good energy transfer between the charging device 85 and the energy store of the lamp 100 is always guaranteed, regardless of the set inclination of the lamp 100 .
- FIG. 7 shows a 90° rotated sectional view of the foot section 11 positioned on the loading device 85, in which the weight has been omitted for reasons of clarity. It can be seen that a shaft 71 protrudes laterally from the motor 70, over which a drive belt of the belt drive runs, which interacts with the pulley connected to the drive wheel 75 (not visible in the figure) and thus causes the movement of the endless belt 97.
- the motor 70 is fixed on the aluminum profile 90, with a retaining bracket 72 also being provided between the motor 70 and in the aluminum profile 90, which is used for the rotatable mounting of the pendulum 75.
- the pendulum 75 in turn has a first leg 78 and a second leg 79 at its end facing away from the second antenna 76 .
- the two legs 78 and 79 are spaced apart from one another transversely to the longitudinal extent of the aluminum profile 90 in such a way that the weight 20 (not shown in FIG. 7) can pass between the legs 78 and 79 .
- the base weight 50 has a slot 55 through which a connecting section 77 of the pendulum 75 runs.
- the connecting section 77 connects the point at which the first leg 78 and the second leg 79 are brought together with the second antenna 76 necessary space between the foot weight 50 and the foot portion 11 to create.
- Spacers 51 and 52 are provided between the base weight 50 and the base section 11 in order to reduce undesirable, in particular sharply defined, shadow formation. These create a gap between the outer surface of the foot weight 50 and the inner surface of the foot section 11. As can be seen from the illustration, these spacers 51, 52 can be attached in different ways: on the one hand, an insertion into corresponding recesses of the Foot weight 50 possible, on the other hand, the spacers 51, 52 can also be formed directly on the foot weight 50.
- FIG. 8 shows an enlarged representation in order to clarify the suspension of the pendulum 75 once again.
- the aluminum profile 90 can be seen in the middle, which, as can be seen from the illustration, can be a standard profile, in particular an extruded profile, in which grooves are formed on all four longitudinal sides.
- the grooves 88 and 89 formed on the side serve to carry the weight 20 which is suspended from the aluminum profile 90 via a first arm 22 and a second arm 23 .
- the first arm 22 and the second arm 23 are each L-shaped with the shorter ends facing each other and engaging in the grooves 88 and 89, respectively.
- the drive device i.e.
- the motor 70, and the movement transmission elements belt drive, endless belt 97, drive wheel 95 and driven wheel 96 towards the weight 20 have to overcome a frictional force so that the first arm 22 and the second arm 23 in the Groove 88 or 89 of the aluminum profile 90 can slide.
- the load transfer for the weight 20 is implemented using ball bearings.
- an upper run 97.1 and a lower run 97.2 of the endless belt 97 run in the grooves of the aluminum profile 90 which are directed towards the upper side or towards the lower side.
- the lower strand 97.2 is using a Connecting element 21 is firmly connected to the weight 20, so that the weight 20 follows a movement of the lower run 97.2 and thus ultimately of the endless belt 97.
- a retaining bracket 72 is provided between the motor 70, which is not shown in FIG. 8, and the aluminum profile 90. This mount
- the 72 is essentially U-shaped, with the orientation of the holder 72 being chosen such that the two legs of the U-shaped holding bracket encompass the aluminum profile 90 .
- An articulated connection is formed between the two legs of the U-shaped holding bracket 72 and the first leg 78 and the second leg 79 of the pendulum 75 . In the simplest case, this can be achieved by providing bores in the U-shaped holding bracket 72 or, more precisely, in its legs, into which cylindrical ends of the first leg 78 and the second leg 79 of the pendulum 75 engage.
- a bearing with reduced friction can be provided.
