Description

[0001] The invention relates to a motif sleeve for reversible mounting on an LED light. State of the art

[0002] Lampshades are devices attached to a light fixture that serve various purposes. These lampshades are intended, in particular, to dim light that is too intense for the eyes; to concentrate the light on specific areas, such as a reading area; to reduce the effects of radiant heat from lamps; to balance the dominant colors of a light source; to create a pleasant atmosphere in the room; and to be decorative even when the lamp is not illuminated.

[0003] Lampshades are often used as lighting objects and light sources that create a pleasant atmosphere in a room. Lampshades are made from a variety of materials, such as fabrics, lacquers, parchment, paper, plastics, and the like.

[0004] Numerous types of lamps exist for illuminating rooms or areas used by people. In a well-known and widespread design, lamps consist of a centrally positioned electric light source, such as a light bulb, and an outer shade surrounding the light source to prevent glare by dampening, directing, or scattering the emitted light.

[0005] LED light sources are a well-known type of light source. LED light sources are electric light sources that use light-emitting diodes to generate light. LEDs are among the most energy-efficient light sources. The lifespan of LEDs can be up to 50,000 hours. LED lamps require less electrical power for the same brightness. They achieve a higher efficiency and are therefore more energy-efficient. LEDs are typically more economical than most other light sources.

[0006] Often, individual customer requests need to be accommodated and the lampshades designed according to the customer's vision, and possibly also be interchangeable or replaceable.

[0007] DE 1684622 U discloses a lampshade in which, on one or more wire rings, e.g. hard foil, acetylcelloid or polytherm, laminated or unlaminated, is held together detachably by means of snap fasteners.

[0008] The use of snap fasteners has the disadvantage that many are required to ensure a snug fit of the lampshade and thus an aesthetically pleasing, uniform shape. At the same time, attaching snap fasteners is time-consuming and expensive due to their small size. When only a few snap fasteners are used, the materials mentioned tend to warp due to humidity and the heat from the light source, becoming wavy in the area between the snaps.

[0009] DE 20 2010 015 722 U1 discloses a lampshade with at least one support and a shade made of a flexible material web, which can be reversibly connected to the support and closed to form a shade. DE 20 2010 015 722 U1 teaches the use of hook-and-loop fasteners or magnetic closures as means for reversibly connecting the shade to the support and closing the material web to form a shade.

[0010] The fastening solutions disclosed in DE 20 2010 015 722 U1 have the disadvantage of being either complex and expensive to produce or difficult to install. Magnetic fasteners are relatively expensive and, due to their weight required to achieve sufficient holding force, require complex fastening methods. The use of hook-and-loop fasteners is difficult to install because both sides of the fastener must be precisely aligned to achieve a stable and aesthetically pleasing result. This is particularly challenging with hook-and-loop fasteners that run continuously along the long sides of the material, as once attached, the fastener cannot be repositioned or straightened during the fastening process.When the hook-and-loop fasteners are positioned at the edge of the material, unsightly fibers may become visible at the top and bottom edges of the lampshade, protruding beyond the lampshade's rim. Exposed hook-and-loop fasteners also collect dust, and the edges can darken over time.

[0011] The object of the invention is therefore to provide an interchangeable lampshade for LED light sources that enables easy-to-assemble, reversible installation of the lampshade and a good light pattern with interchangeable aesthetics. Disclosure of the invention

[0012] The invention is disclosed by the features of the main claim. Embodiments and further developments are the subject of the subsequent claims.

[0013] A decorative cover for reversible mounting on an LED light is disclosed. The LED light can be, in particular, cylindrical and upright. The LED light can have a dimming function. The decorative cover is designed to serve a decorative function. For this purpose, it is printed with decorative elements. It thus serves as a decorative cover for the LED light. The decorative cover is made of plastic. It is transparent, printable, and made of a shape-changing film.

[0014] To change the decorative cover, it features a reversible closure that can be connected or disconnected. The cover can therefore be removed from the LED light by pulling or opening the closure. An alternative cover, perhaps with different decorative elements, can then be closed and attached around the LED light or slipped over it. The closure is designed as a tab closure. Interlocking connecting elements are provided, particularly on the short sides or edges of the decorative cover. These are grooves on one short side and tabs on the opposite short side. The connecting elements are joined by inserting the tabs into their respective corresponding grooves.

[0015] The designs printed on the decorative wrist warmer can vary. They can include wedding, birthday, Christmas, or Easter motifs, or custom designs with names, animal motifs, or similar themes. The wrist warmer is transparent, or at least has transparent areas, to allow the decorative elements to show through.

[0016] Further advantages and advantageous embodiments of the invention can be seen in the following description of the figures, the drawings and the claims.

[0017] An exemplary embodiment of the solution according to the invention is explained in more detail below with reference to the accompanying schematic drawings. It shows: Fig. Figure 1 shows a top view of a motif cuff with locking devices and Fig. Figure 2 shows an isometric view of the closed motif cuff.

[0018] In Fig. Figure 1 shows a decorative sleeve 10. The decorative sleeve 10 has connecting elements for the reversible connection of edges 12. The decorative sleeve 10 can be arranged on an LED light. The LED light can be, in particular, cylindrical and upright. The LED light to be enclosed can have a dimming function. The decorative sleeve 10 is designed to have a decorative function. For this purpose, it is printed with decorative elements. It thus serves as a decorative sleeve 10 for the LED light, allowing for interchangeable decorative design. The decorative sleeve 10 is, in particular, made of plastic. It is transparent, printable, and made of a shape-changing film.

[0019] To facilitate changing the decorative cover 10, it features a reversible closure that can be connected or plugged in and disconnected. The decorative cover 10 can thus be removed from the LED light by pulling it off or opening the closure. An alternative design, for example with different decorative elements, can then be attached around the LED light or slipped over it. The closure is designed as a reversible tab closure for this purpose. Interacting connecting elements are provided, particularly on the short sides or edges 12 of the decorative cover. On one short edge, these are grooves 14, and on the opposite short side, they are tabs 16. The connecting elements are joined by inserting the tabs 16 into the respective opposing grooves 14.

[0020] The designs printed on the motif cuff (item 10) can vary. They can include wedding, birthday, Christmas, or Easter motifs, or custom designs with names, animal motifs, or similar. The essential requirement is that the motif cuff is transparent or at least has transparent areas.

[0021] Fig. Figure 2 shows the motif cuff 10 in its closed state. The tabs 16 of one edge 12 engage in the grooves 14 of an opposite edge 12 and are thus reversibly connected to each other.

[0022] All features shown in the description, the following claims and the drawings can be essential to the invention, either individually or in any combination. Reference symbol list 10 Motif cuffs 12 edge 14 Nut 16 tab QUOTES INCLUDED IN THE DESCRIPTION
