Definitions

  • the present invention relates to a lamp and more particularly to a holder for a lampshade.
  • the lamp can be equipped with an LED bulb.
  • lamps for example, those for the work area, which are optimized with respect to their light output and radiation, as well as those for the private sector, which are often designed in view of their appearance and their decorative effect.
  • the German utility model application DE 7 027 149 U discloses a lamp which may be in the form of a floor or table lamp.
  • This lamp should have a light bulb in a socket and a screen covering the socket.
  • the shade is attached to the base of the lamp by means of an outwardly directed retaining clip.
  • the headband should be movable radially inwardly by means of an actuator. By providing such an actuator, it should be easy to replace the screen of the brackets. For this reason, umbrellas made of a thin and sensitive to external influences material should be usable.
  • the registration WO 2007/036064 A1 discloses an optical device for LED light sources.
  • This optical device is intended for a favorable light distribution of the light of an LED light source.
  • This additional item may also be an optically conductive solid.
  • the corresponding light-conducting solids are elaborately optimized to produce an optimal beam path. For example, cavities are provided in the solids.
  • the present invention seeks to improve the state of the art. It should be created a lamp that gives a good light without high technical effort, but at the same time is decorative. In particular, it has also posed a problem to provide a lamp in which a natural material can be used in an advantageous manner. This natural material should be optimal both in terms of its procurability and in terms of its aesthetic appeal as well as with regard to the function of the lamp. With regard to the holder for the lamp, it was important to choose a simple elegant construction that can be combined with a natural material. The holder should provide a good grip even with deviations in the dimensions of the natural material.
  • the invention thus relates in a first aspect, a holder for a lampshade.
  • This holder should have a (preferably) arranged on a central axis socket and a plurality of webs.
  • the webs should extend radially away from the center axis. At least one web should be able to be inserted into a corresponding receiving opening of a lampshade.
  • the web should, based on remaining parts of the holder, at least the socket, extend along a first radial axis.
  • tangential restoring forces act, by means of which a clamping force is generated for holding the lampshade.
  • the tangential Restoring forces / the clamping force should take effect between at least two receiving openings of the lampshade.
  • the web has, based on the other parts of the holder, so at least relative to the version, a rest position. In this rest position, the holder is not connected to the lampshade and there are no special external (about beyond gravity) forces on the web.
  • This rest position is described by the radial axis of rest.
  • a joint should be at least tangential a deflection of this axis possible.
  • An elastic connection of the webs with the socket has also proved to be useful. In this deflection, however, restoring forces are to be generated. By this restoring forces, which act approximately in the direction of a tangent to a circle about the center axis, a clamping force for mounting the lampshade is constructed.
  • the holder comprises at least two or more webs.
  • a lampshade can be defined by a plurality of webs.
  • Corresponding restoring forces can also be exerted by a plurality of webs.
  • the webs may be inclined to the center axis towards the front. This usually allows a particularly easy insertion of the webs in a lampshade.
  • the socket is designed for receiving a light source at the front.
  • an LED lamp or an incandescent lamp or an energy-saving lamp is used as the lighting means.
  • version is intended to generally refer to a central body, even for individual cases in which a light source is not or not attached directly to the central body.
  • the webs are elastic both on a tangential displacement from its radial axis and elastic with respect to an inclination towards the center axis.
  • the required clamping force is applied by this elasticity, so that the webs do without further hinge means and means for generating a restoring force.
  • the required clamping force can also be wholly or partly constructed by the restoring force which occurs against a tilt towards the center axis.
  • the webs taper away from the socket. This allows a material-saving construction of the webs, since the forces occurring near the socket are greatest. Furthermore, such a construction allows a graceful appearance of the holder.
  • the web ends have a first radius relative to the center axis in their rest position. If at least one web can be moved towards the center axis, the radius can be reduced by this mobility.
  • This reduced radius is referred to here as a mounting radius and allows the good connectivity of the holder with the screen, but also a good solubility of the screen of the holder.
  • this mobility of the mounting radius is at least 10%, preferably 20%, but preferably 30%, or more, smaller than the first radius. This preferably applies to all webs.
  • the invention also relates to a lamp.
  • This lamp should have a holder of the type just described.
  • a holder for a lampshade thus has a socket arranged on a center axis, a plurality of webs which extend radially away from the center axis, wherein at least one web extends along a radial axis, and can be inserted in a receiving opening of a lampshade, and wherein the at least one web elastically connected to the socket, and act on deflection from the radial axis tangential restoring forces, by which a clamping force relative to the support of the lampshade can be built.
  • a set of first angles are to be enclosed by the radial axis of rest of the webs when the webs are in their rest position.
  • the radial axes of the webs describe a second set of angles.
  • the set of first angles deviates from the second angle set. A deviation is understood to mean the departure of at least one angle between the two sets or sets of angles.
  • the invention in another, also quite independent aspect, relates to a lampshade, which has receiving openings for webs.
  • the receiving openings should be arranged in the middle along a second radius.
  • the lampshade should have an opening for passing the holder, which has a third radius.
  • the corresponding web ends should have a first radius.
  • the second radius should be greater than the third radius and the first radius greater than the second radius.
  • the web ends of the web rim jointly describe a mean diameter, which results as a double arithmetic mean of the web radii.
  • the invention also relates to a lamp in which a lampshade is provided, the receiving opening has a third average diameter, the web recordings have a second average diameter, and the web ends a first average diameter, wherein the second average diameter is greater than the third average diameter, and the first average diameter is greater than the second average diameter.
  • the invention also relates to a lamp which has a machined holder, but in which the lampshade is a natural product. According to the invention it has been found that sea urchins can be used particularly advantageously as lampshades.
  • the sectional view of the Fig. 1 shows a good overview of the main components of the lamp according to the invention 10.
  • the dashed lines shown elements in the lower half of the figure are slightly behind the cutting plane.
  • On the screen web images 14 are provided.
  • the holder 20 has webs 22 which engage in the web receptacles 14.
  • a socket 24 is provided in the center of the holder 20, a socket 24 is provided.
  • a bulb receptacle 26 is provided.
  • a lighting means 30 in the form of an LED lamp.
  • the socket 24 has a mounting receptacle 32. With the help of this mounting receptacle 32, the holder 20 can be mounted. Further, adjacent to the mounting hole 32, a grommet 34 is provided on the socket 24.
  • Fig. 2 shows the lamp 10 in a perspective view obliquely from behind. It can be seen here how the holder 20 is centered in the main opening 16 of the screen 12. The webs 22 of the holder 20 project into web receptacles 14 of the screen 12. These web pictures essentially have the form of eyelets here.
  • the Fig. 2 shows a lampshade 12 in the form of a sea urchin. Of course, naturally occurring sea urchins have eye-shaped openings, which can be used as bridge pictures. According to the invention, it is ideal to use a natural material which can be used both as a screen 12, but which also has suitable web receptacles 14 in its natural form.
  • Suitable web receptacles 14, for example in the form of eyelets, can additionally be inserted. Such an insertion could be done, for example, by gluing web clips 14 with the screen 12.
  • the Fig. 3 shows from a similar perspective as Fig. 2 the screen 12 without the bracket 20.
  • the sea urchin also has a main opening 16, which provides enough space for the holder 20 and through which the webs can be well introduced.
  • the main opening 16 is opposite to another opening 18, through which a narrow centered cone of light can escape.
  • regular sea urchins are generally preferred, in particular those from the superfamily Echinoidea Regularia.
  • the Fig. 4 shows in perspective view also half from behind a holder 12 according to the invention. It can be seen that this holder 20 is executed overall graceful and material-saving.
  • the socket 24 occupies a small volume, and extends radially only slightly from the center axis to the outside.
  • the Fig. 5 shows a rear view of the holder 20.
  • the holder has the socket 24 in the middle. It can be seen on the mounting receptacle 32, which marks the center of the holder 20, and through which runs centrally in the direction of the center axis. Above and below the mounting receptacle 32 is ever a cable bushing 34A and 34B can be seen. Radially from the socket 24 outwardly go five webs, the webs 22A, 22B, 22C, 22D and 22E. These webs are arranged at a constant angle to each other. The angular distance of the webs is thus 72 degrees.
  • For the web 22B is the radial axis A 1 in the rest position of the web (also called "radial axis of rest").
  • a dashed line also indicates a deflected position of the web. For this position, the radial axis A 2 is entered. Such a deflection in the tangential direction may be present when the web 22B has been introduced into the web receptacles 14 of a lampshade 12. This deflection creates tangential restoring forces. Unlike those shown, the web itself may also be bent, even if it is deflected into its rest position, but webs formed entirely of elastic material are even preferred in the context of this invention , In the context of this invention, therefore, generally both webs are considered to be appropriate, which, when holding a lampshade, are bent or which are bent relative to their outgoing from the socket radial axis of rest or in which both occur.
  • Fig. 6 shows a front view of the holder 20, in which one looks along the center axis of the holder 20. So you can see here on the bulb receptacle 26.
  • the webs taper towards the outside conically. Accordingly, the cut surface along the cut F 1 is larger than the cut surface along the cut F 2 , which is farther from the socket 24 than F 1 .
  • the corresponding cut surfaces can, as shown, be oval. Circular or rectangular cuts and corresponding web shapes are also useful.
  • the required clamping force for attachment of the screen can also be constructed in whole or in part by the clamping forces acting between the receiving openings and positively inserted webs 22.
  • Fig. 7 shows a section through the holder 20 along the sectional plane VII - VII as in Fig. 5 shown.
  • the center axis M runs in this illustration
  • the plane E f is perpendicular to the center axis M and extends centrally through the foot 36 of the web 22A. It can be seen that the web is inclined relative to this plane E f forward to the center axis. This inclination already exists in the rest position of the web. It can be described by an angle ⁇ 1 to the plane E f , which is preferably between 5 and 45 degrees, particularly preferably between 10 and 25 degrees.
  • the web also has a radius r 1 (measured in the plane E f ) in the rest position.
  • the web foot is movably connected to the socket 24.
  • the web can be further bent to the center axis.
  • This movable connection can be generated by a joint, but easier by the elasticity of the web.
  • the web takes in this pre-bent position then an angle ⁇ 2 to the plane E f , which is greater than the angle ⁇ 1 , preferably at least 10 °, 20 ° or 30 ° greater.
  • This bending of the web towards the center axis causes the land radius to be reduced relative to the center axis.
  • the reduction to the radius r ' 1 allows easier insertion of the web into the screen 12.
  • a corresponding mobility towards the center axis is preferably given for all webs 22. Accordingly, the radius reduction also leads to a reduction in diameter of the web rim as a whole.
