Definitions
- the invention relates to a ring light.
- Ring lights are lights that are used, for example, in furniture construction and have a ring-shaped light surface that usually runs around a gap. Ring lights in the sense of this invention can be circular, oval, rectangular, square or otherwise designed, as long as there is a light section that runs completely or at least partially around a gap. A ring shape does not have to be a circular ring shape.
- the object of the present invention is to create a ring light which is suitable for both installation variants and offers optical advantages, particularly in the retrofit variant. This object is achieved by a ring light with the features of claim 1 and a furniture part with the features of claim 9. Advantageous embodiments can be found in the subclaims.
- the ring light according to the invention has a ring-shaped, in particular circular, oval, rectangular, square, housing which runs around an intermediate space and in which a light source, preferably an LED light source, is accommodated in a corresponding ring-shaped, in particular circular, oval, rectangular, square manner, as well as a ring-shaped, in particular circular, oval, rectangular, square, cover element which closes the housing.
- the housing and the cover element enclose the ring-shaped, in particular circular, oval, rectangular, square, light source and thus protect it from environmental or surrounding influences.
- the cover element is at least partially transparent, opaque or at least translucent in order to at least partially let through the light emitted by the light source.
- CSP LEDs can preferably be used as LED light sources. Due to the small installation space achieved with this technology, these allow a reduction in the height of the ring light according to the invention and enable a glare-free implementation. This makes it possible to create a light with a comparatively low installation height.
- the LED lamps used can be complete closed rings, but it is preferably provided that the lamps according to the invention consist of LED segments In this way, in terms of sustainability, less waste per area can be achieved in the manufacture of the lamps according to the invention, since the corresponding LED segments can be arranged on a material blank in a much more space-saving manner than complete rings.
- the light source is electrically connected to a cable via contacts, preferably contact surfaces, directly or indirectly via a plug.
- the cable is led out of the housing as a flat cable or a protruding leadthrough is arranged on the side of the housing facing away from the light source, through which the cable, in particular as a flat cable, is led.
- the use of a flat cable it is possible to subsequently arrange the ring light on a piece of furniture or on a wall or ceiling.
- the electrical connection from the power source to the light source is established via the flat cable, which can be arranged on a surface and therefore hardly takes up any space.
- the carrier material of the flat cable is colored so that it matches the color of the surface to which it is applied, the cable routing is hardly noticeable.
- a protruding hole is arranged on the housing on the side facing away from the lamp, through which the cable is led, the ring light is suitable for installation in a piece of furniture or another object.
- the cable is then led into the support and can be led under the surface or through the interior.
- flat cables are particularly suitable because they can be easily guided in flat grooves or through cross holes, whereby flat grooves or cross holes usually do not affect the stability of the support, preferably a piece of furniture.
- a flat cable when used, this is made from a strip of a flexible insulating material, in particular plastic material, and conductor tracks and contacts or contact surfaces applied thereto.
- a flexible insulating material By using a flexible insulating material, the flat cable can be easily adapted to the topography of the surface and thus facilitates the installation of a ring light.
- the applied conductor tracks and the contacts or contact surfaces are preferably arranged on the side of the flat cable that faces the surface on which the flat cable is/is arranged.
- the cable is soldered to a contact or contact surface of the light source. Soldering the contacts allows a firm and therefore very stable connection, which increases the service life of the connection, especially with larger current flows.
- Other connection options are of course also conceivable, such as plug contacts. The same applies to the LED segments mentioned above, if they are used.
- the housing and/or the Line comprises a self-adhesive layer.
- a self-adhesive layer allows quick installation without the need for additional holding elements. This means that the ring light can be installed pre-assembled and other holding elements such as screws do not have to be covered after assembly.
- the self-adhesive layer mentioned can be designed in such a way that the light can be detached from a piece of furniture when it is disposed of or replaced. The adhesive layer can therefore be detached, for example by being stretched and thereby losing its adhesive power. This also allows for more resource-efficient disposal, since now only the light, rather than the entire piece of furniture, would have to be disposed of as electronic waste.
- the components of the ring light according to the invention are connected to one another by plugging or clipping, preferably without tools. In this way, the separation of a defective lamp into its components is made even easier and the volume of electrical waste is significantly reduced, since only cables or the lamps or LED components need to be disposed of as such.
- an opening is provided on the housing, at which the feedthrough is arranged.
- the feedthrough is preferably provided for the case that the ring light is used as a built-in variant.
- a corresponding feedthrough is then provided in the furniture part, whereby the term furniture part is used in this case as a synonym for carrier objects in general.
- a recess is made which accommodates the feedthrough and/or, at least partially, the housing.
- the cable is in contact with the light source through the opening.
- a cable duct is preferably led through the relevant furniture part to the recess for the feedthrough.
- the cable is a cable with at least 2 cores, preferably 3 cores.
- the aim is to achieve the lowest possible number of cores in the cable.
- a 2 core cable can be used if the ring light does not require earthing. If the ring light does require earthing, a 3 core cable is recommended so that the earthing cable does not have to be laid additionally.
- the flat cable has at least one of the following properties: a) a current carrying capacity of 4-8 A, preferably at least
- the requirements for the cables vary depending on the area of application or the type of light source used. If a low-voltage light is used, the current-carrying capacity is particularly important (without neglecting the other criteria too much). For a household power supply or even a high-voltage supply, the dielectric strength is particularly important.
- the width of the cable is very important when laying the cables, particularly for concealed cables, as they are to be laid in prefabricated ducts, for example. Strain relief is particularly advantageous where the cables are subjected to tension when laying the cable or when mounting the ring light. This tension should not put any strain on the contacts if possible.
- the length of the cables should be such that the free end of the cable reaches the contact point of the power supply coming from the voltage source. It has been shown that a cable length of between 200 and 400 mm is sufficient, particularly in furniture construction, with a length of 300 mm being preferred.
- the thickness of the flat cable depends on a high degree of flexibility, but this must be combined with a conductivity that meets the requirements.
- a self-adhesive layer is particularly preferred if the light is to be installed later. A self-adhesive layer makes installation easier and eliminates the need for additional means of holding the cable, so that it can be installed easily and almost unobtrusively.
- the object according to the invention is also achieved by a furniture part on which at least one ring light is arranged according to a the embodiments described above, wherein the cable is guided through a recess in the furniture part or is glued as a flat cable onto a surface of the furniture part.

- Figure 11 - shows the top view of a round ring light.
- Figure 1 shows a perspective view of a ring light 1 in which the luminous surfaces are arranged around a gap Z.
- the luminous surface is arranged approximately squarely around the gap Z. Approximately square because the corners of the square are rounded.
- the structure is shown in an exploded view of the ring light 1 in Figure 2.
- the lamp carrier 11, which contains the lamp 11a and contacts or contact surfaces 11b, is inserted into a receiving housing 12, which is designed as a circumferential groove.
- the groove of the receiving housing 12 is covered by a cover element 10, which shields the lamp carrier 11 from the outside.
- the cover element 10 is generally at least partially transparent to light, and is preferably transparent, translucent or translucent.
- An opening 12a is let into the base of the receiving housing 12, through which the lamp carrier 11 can be contacted.
- a plug 15 is arranged in a feedthrough 14 for this purpose.
- a wiring system in advance that is not visible from the outside and to which the ring light is connected by means of a plug connection.
- the plug connection can be removed and the replacement can be carried out without The wiring can be renewed.
- a self-adhesive layer is arranged under the housing 12. This means that the ring light can be easily and safely arranged in or on the furniture part 2 without the need for any other fixing such as screwing.
- FIG 3 shows a detail of a section AA (Fig.1) through the ring light 1.
- the detail shows the area where the feedthrough 15 is arranged.
- the ring light 1 itself, or more precisely the housing 12 with the lamp holder 11 and the cover element 10, is arranged on a furniture part 2 by means of a self-adhesive layer 13 such that the feedthrough 15 dips into a recess 2a in the surface of the furniture part 2.
- a plug 14, which is correspondingly connected to the lamp holder 11 at the contacts or contact surfaces 11b, has the contact area in a second recess 2b below the surface so that a line 16 (not shown here), which is led through this recess 2b, can be connected to the plug 14.
- the cable feed cannot be seen by an observer from the outside.
- a further function of the feedthrough 15 is to also serve as a centering pin for the arrangement of the ring light 1. Inserted into the recess 2a, the feedthrough 15 determines the position of the ring light 1, and if the recess 2a is sufficiently narrow, the orientation of the ring light 1 is determined by the self-adhesive layer 13.
- Figure 4 shows an embodiment of the cable 16.
- Figure 4 shows a 3-core cable 16 with a contact surface 16a towards the lamp and, at the other end of the cable 16, a contact surface 16b for the power supply.
- the contact surface 16a towards the lamp can be a plug connection that can be plugged into a plug 15, as shown in Figure 3.
- This contact surface 16a can, however, be a solderable contact surface 16a or a clampable contact surface 16a.
- the contact surface 16b is arranged towards the power supply. A plug, clamp and/or solder connection is also possible at this end.
- the end with the contact surface 16b for the power supply is provided with a strain relief. If the ring light 1 is removed from its seat, the cable 16 can be pulled. To ensure that the contact surface 16b is not subjected to tensile stress and thus damaged, the end can be held in place by a strain relief.
- the length of the cable is arbitrary, but it should be sufficient for the connection from the power supply to the ring light 1.
- a length between 200 and 400 mm is sufficient for most applications; a length of 300 mm is preferred for most applications.
- the cable 16 which is preferably designed as a flat cable, it should not be too thick (high) and not too wide.
- a thickness of 0.1 to 0.5 mm is preferred, although it has proven advantageous to use a thickness of 0.3 mm.
- a width of 5 to 10 mm has proven advantageous. , whereby a width of 6.5 mm is preferred.
- More than 3-core cables 16 are also conceivable. They are useful if the ring light 1 is to contain additional functions that can be controlled independently or if several ring lights that can be switched independently of one another are to be operated via the cable.
- Figure 5 shows the exploded view of the ring light 1 in Figure 2, supplemented by the cable 16.
- Figure 5 shows two cables 16 which are arranged at different points on the lamp carrier 11.
