Definitions

  • the invention relates to a light string with a plurality of light sources.
  • Fairy lights as they can be attached to Christmas trees but also to other objects, such as house walls, doors or door frames or the like, for lighting or decoration, are known. Since in such fairy lights, the light sources are relatively large and are arranged so that they protrude significantly from the fairy lights, there is a risk during assembly or disassembly of the cable tangle and the ball formation. If the fairy lights are to be reinserted into the packaging after use, this is virtually no longer possible since the intended insertion positions can no longer be achieved by the formation of the balls. A corresponding storage in the packaging is therefore relatively time-consuming or the fairy lights are simply inserted into the packaging in the entire ball produced. In addition, by these known lights through the cable tangling and kinking and cable breaks occur and thus the functioning of the fairy lights are significantly affected.
  • the entire fairy lights are relatively heavy and unwieldy due to the relatively large and protruding light sources.
  • the assembly and disassembly is Therefore, relatively complex and the candle-like protruding from the fairy lights light sources often remain due to their size and weight not in the appropriate mounting position, but tilt or dissolve from the mounting position. The fairy lights then hang loose at this point in the room.
  • the font WO 01/25681 shows an elongated LED lighting system, which provides two electrical conductors in a plastic encapsulation. Between the electrical conductors, a plurality of LEDs are shed.
  • the font DE 203 09 070 U1 shows a lighting device in which a plurality of series-connected LEDs are arranged on a flexible printed circuit board. The LEDs are driven by a decoder connected to two tracks on the circuit board.
  • a light string according to the invention comprises a plurality of light sources, which are preferably arranged at a distance from each other in the fairy lights.
  • the light sources are integrated into the fairy lights and embedded in a carrier part of the fairy lights.
  • This configuration makes it possible for the fairy lights to have substantially the same thickness or the same diameter over their entire length. Even at the locations where the light sources are arranged, the diameter or the configuration of the light string is not thicker or only slightly thicker than at the locations where no light sources are arranged.
  • This embedded mounting of the light sources the handling can be significantly improved. Cable entanglement during assembly or disassembly can be prevented. Since the bulbs quasi no longer stand out or only insignificantly from the fairy lights, the introduction into a package after use can be done with little effort and expediently. Cable kinks or cable breaks due to improper insertion of the fairy lights into the packaging can be prevented.
  • the introduction into intended positions in the packaging can be done easily by the light string according to the invention.
  • the fairy lights are particularly band-like and flexible and can thus be bent and deformed in many ways, to attach them to differently shaped and formed objects, for example on a tree or a door frame or otherwise.
  • the light string preferably comprises a plurality of fastening elements.
  • hooks or clips or plug-in tabs or the like may be provided for this purpose, which are connected to the fairy lights and arranged thereon.
  • the light sources are surrounded by a tube-like carrier part.
  • the light sources are thus arranged completely inside a tube.
  • very narrow design of the fairy lights can be made possible by this design of the support member and a complete embedding of the light sources. Damage, such as scratching or the like, can be prevented.
  • the tube-like support part completely surrounds the light sources can be ensured particularly advantageous protection against pollution.
  • the tubular support member extends over the entire length of the fairy lights.
  • this may be formed of a flexible translucent material.
  • a very soft tube which allows the attachment of the fairy lights to a variety of objects with different and also relatively strong twists.
  • a light source is embedded substantially flush with an outer side of the carrier part in the carrier part.
  • the outside of a light source is exposed in such an embodiment.
  • the light emission can be improved. Due to the substantially flush arrangement and embedding of the light source in the support part on the one hand again a protection against damage can be ensured and on the other hand, a compact and space-minimized design possible.
  • the fairy lights comprise an upper part and a lower part, which are connectable.
  • the upper part of the light sources are arranged and in the lower part cable channels are each arranged with at least one cable.
  • the initially separately provided parts can then be formed with the respectively male components and then connected to each other in retrospect to complete the fairy lights. For connection, jamming or latching or the like may be provided.
  • At least two, in particular three, mutually parallel cable channels are formed in the lower part. It can also be provided four cable channels, which then a control of red-green-blue (RGB control) color channels is possible.
  • RGB control red-green-blue
  • cutting elements are integrated in the upper part, wherein each light source is electrically contacted with two cutting elements.
  • the cutting elements are arranged so that specific cables are cut in the cable channels during assembly of the upper part with the lower part and thereby electrical contact is ensured.
  • the cutting elements are provided only for making electrical contact with the cables, but not arranged for complete severing of a cable.
  • Cable separators are arranged in the upper part and a cable separator is assigned to each light source.
  • a cable separator is an element which, when connecting the upper part to the lower part, completely cuts through a cable arranged in a cable channel. Again, the individual arrangement of a cable separator allows a precise and specific separation of a cable. When assembling the upper part with the lower part of this integrated cable divider thus automatically a severing of a desired cable is achieved. The connecting cables no longer have to be cut by hand.
  • the electrically insulating sheath of the cable is separated so far that an electrical contact of the cutting element with the inner electrical guide element, such as a copper wire or the like, is ensured.
  • a cutting element may for example be designed as a so-called cutting tongue and have on the side facing a cable a V-shaped notch.
  • a cable separator preferably comprises a cutting part which faces a cable.
  • a sheath in particular a plastic sheath is provided, which is a cutting part exhibiting element surrounds the cable separator.
  • the light sources are designed as light-emitting diodes. This is particularly advantageous in an embodiment of the fairy lights, in which an upper part and a lower part is present, which must be joined together. Since this assembly is accompanied by mechanical shocks, and light-emitting diodes are insensitive to such influences, damage to the light sources during assembly can be avoided.
  • Fig. 1 is a schematic sectional view of a first embodiment of a belt-like, flexible and thus diverse deformable fairy lights 1 shown.
  • the light string 1 is shown in a partial section of its total length.
  • the light string 1 has a plurality of light sources 2, 3, which are formed in the embodiment as light-emitting diodes and spaced from each other in the fairy lights 1 are arranged.
  • the light sources 2 and 3 are connected in series with each other and connected to each other via a signal line 4. Further Signal lines 5 and 6 lead to other light sources, not shown.
  • the fairy lights 1 further comprises a hose-like carrier part 7, which completely surrounds the light sources 2 and 3 as well as the signal lines 4, 5 and 6.
  • the tubular support member 7 is formed of a highly flexible and translucent material.
  • the light sources 2 and 3 are thus completely integrated into the light string 1 and embedded in the carrier part 7.
  • the light sources 2 and 3 are arranged and dimensioned by their arrangement and embedding in the support member 7 so that the light string 1 over its entire length has substantially the same thickness. Also at the locations where the light sources 2 and 3 are arranged, this is the same or insignificantly greater than the thickness or the diameter at the points of the light string 1, where no light sources 2 and 3 are arranged.
  • a further embodiment of a light string 1 is shown in a schematic sectional view. Also in Fig. 2 only a partial section of the entire length of the light string 1 is shown.
  • the light string 1 comprises an upper part 1a and a lower part 1b, which are provided as separate parts. Both the upper part 1a and the lower part 1b are realized as carrier parts.
  • a plurality of light sources (shown is only the light source 2) are embedded in the upper part 1a formed as a carrier part.
  • the light source 2 is embedded in the upper part 1a and integrated so that they are almost flush with the top or the lower part 1b facing away from the upper part 1a is arranged. Outwardly, the light source 2 is thus exposed in this embodiment. Also by this configuration, a relatively compact and flat construction of the light string 1 in its thickness or its diameter can be made possible.
  • the light source 2 is electrically contacted by two signal elements 10 and 11 with two cutting elements 8 and 9, which are also integrated in the upper part 1a.
  • a cable separator 12 is integrated in the upper part 1a.
  • the cutting elements 8 and 9, which are formed as cutting tongues, and the cable separator 12 are integrated in the upper part 1a so that they protrude downwards from the upper part 1a.
  • a plurality of mutually parallel and spaced-apart cable channels 13, 14 and 15 are formed, as in Fig. 3 can be seen in plan view.
  • a cable is arranged in each case.
  • a cutting element 8 is shown in simplified side view. This is dovetailed and has an upper edge 81 on which the signal line 10 is contacted. On the opposite side, the cutting element 8 has a V-shaped notch 82 formed in the reverse direction, which constitutes the cutting blade. This is arranged outstandingly from the upper part 1a.
  • a cable separator 12 In Fig. 5 an embodiment of a cable separator 12 is shown.
  • the cable separator 12 has a plastic sleeve 121 which surrounds a member 122, on the underside of a cutting tool 123 is arranged.
  • the plastic sheath 121 extends only partially over the entire length of the cable separator 12th
  • Fig. 6 is a schematic sectional view shown, in which in the assembled state of the upper part 1a with the lower part 1b in a cable channel 14 extending cable 14a is completely severed. It can be seen that the plastic sheath 121 ensures the safe removal of the ends of the severed cable 14a from one another.
  • Fig. 7 to 9 are in plan view respectively in a schematic representation of different versions of contacts in the fairy lights 1 according to Fig. 2 shown.
  • Fig. 10 a simplified circuit concept shown, in which four light-emitting diodes formed in the upper portion are connected in series with each other and between a voltage potential.

  • the arrangement of the cutting elements 8, 9 and 16 and the cable separator 12 is shown.
  • Fig. 8 a corresponding representation is shown in plan view, in this regard, the arrangement in area II in Fig. 10 is shown.
  • Fig. 9 is a further plan view of an embodiment of a switching concept shown, in this regard, the area III in Fig. 10 is shown. Again, the cutting elements 8, 9 and 17 can be seen.
  • the cutting elements 16 and 17 are arranged in each case via two cable ducts 13 and 14 or 14 and 15 and designed for cutting and electrical contacting of the cables arranged in these cable ducts 13 and 14 or 14 and 15.
  • Fig. 7 to 9 are in a simplified schematic representation of the assembled parts 1a and 1b of the fairy lights 1 according to Fig. 2 shown.
  • a retaining connection between the upper part 1a and the lower part 1b can be made possible by jamming, clipping or latching.
  • a mechanically stable connection between the upper part 1a and the lower part 1b can be automatically made possible by generating the cutting with the cutting elements 8 and 9 and the cable separator 12.
  • bulges in the cable ducts 13 to 15 a strain relief of the cable can be ensured.
  • the bulges are formed as wave-like elevations in the bottom of a cable channel and in the longitudinal direction (in Fig. 3 horizontal direction) of a cable duct 13 to 15 spaced from each other. A cable in a cable duct 13 to 15 is thus guided or placed quasi over bump of the cable channel.
