Definitions

  • the invention relates to a lighting device with an elongate strain relief element and with an elongate light strip which carries a multiplicity of electrically operable lamps arranged one behind the other in its direction of extension, the strain relief element and the light strip being surrounded by a transparent, flexible jacket in a parallel position to one another.
  • a lighting device of the type described above can be used in an elevator shaft. From the DE 10 2015 011 999 A1 or the DE 10 2014 105 855 A1 lighting devices are known which can be fixed in the vertical direction in an elevator shaft in order to illuminate the shaft.
  • the lighting device has an upper fastening means and a lower fastening means.
  • the lighting device can be fastened to a shaft ceiling with the upper fastening means.
  • the lighting device can be fastened to the base of the shaft with the lower fastening means.
  • a clamping device is provided in order to clamp the lighting device in the vertical.
  • the fastening means are attached to the two ends of a strain relief element, which is formed by a strap.
  • a flexible circuit board, on which a large number of LEDs are attached, runs parallel to the belt.
  • the strain relief member and light strip extend within a lumen of transparent, flexible tubing.
  • the invention is based on the object of further developing a lighting device in a way that is advantageous in terms of use.
  • the jacket has two chambers that are separated from one another by at least one partition.
  • the light strip extends in a first chamber.
  • the strain relief element which can be formed by a cable, a wire, a belt or another flexible, tensile object, extends in a second chamber.
  • the jacket is designed as a hose, which has a plurality of lumens extending in the hose extension direction, with one of the lumens forming the first chamber and a second lumen forming the second chamber.
  • the tube can be extruded from a flexible, transparent plastic material.
  • the two chambers are separated from one another by at least one partition. Two partitions can be provided.
  • a web which connects two sections of the casing to one another, with a first section forming the first chamber and a second section forming the second chamber.
  • two sections of the casing, each of which forms a chamber can also be connected to one another by two webs.
  • the Webs can extend parallel to each other and connect two partitions together.
  • a third chamber can form between the webs, which is arranged between the first chamber and the second chamber. The third chamber can remain empty.
  • a flexible conductor track preferably extends in the first chamber, on which lamps, in particular light-emitting diodes, are arranged at regular intervals.
  • rectifier arrangements and drivers for the LEDs can be arranged on the flexible conductor track.
  • supply lines which supply the lamps with electrical energy can also be arranged on the conductor track.
  • the strands can run into the extruder head during manufacture of the jacket, for example during the extrusion of a hose forming the jacket, so that they are integrated into the wall of the jacket in an insulated arrangement.
  • the strands can extend parallel to one another. Provision is made for the stranded wires to be connected to contact elements of the flexible conductor track at regular intervals.
  • the first chamber and the second chamber each have a mounting slot.
  • the mounting slot extends in the longitudinal extent of the jacket through one of the walls, for example a wall of the first or second chamber opposite the partition.
  • the flexible wall of the jacket can be opened in order to insert the light strip or the strain relief element into the chamber.
  • This can be carried out using a tool which bends away from one another two wall sections which are separated from one another by the assembly slot, so that an assembly opening opens up into which the strain relief element or the light strip can be inserted.
  • the two chambers have an elongated cross section and run parallel to one another with their longitudinal edges.
  • the walls of the first or second chamber then pointing away from the partition can have the mounting slot.
  • indentations can be provided in the area of two webs running parallel to one another, which depressions are formed running in the direction in which the casing extends. These indentations can be used when the two sections of the shell containing either the first chamber or the second chamber are to be separated from one another. This can be done with a knife or other cutting tool that can be placed in the area of the indentations.
  • the strain relief element preferably formed by a textile belt, protrudes from the second chamber at both ends of the casing and is connected there to a fastening element with which the strain relief element can be fastened to a shaft ceiling or a shaft bottom.
  • a light strip is first prepared as an endless strip, a strain relief element, for example as an endless belt, and a jacket made as a tube, with two strands extending inside the jacket. The two strands can be surrounded by the electrically insulating material of the sheath, so that they can be connected to a 240 volt mains voltage.
  • the light strip is inserted into the chamber assigned to it through a first mounting slot in an outward-facing wall of the first chamber, with the light strip being placed with a mounting surface on a section of the inner wall of the chamber that runs essentially in one plane and is formed by a partition is.
  • the assembly slot can then be closed by laser or ultrasonic welding.
  • the mounting slot can also be glued shut.
  • the strain relief element can be installed in a similar manner.
  • a wall of the chamber assigned to the strain relief element that is opposite a partition wall can have a mounting slot, along which two sections of the chamber wall can be spaced apart from one another, so that an opening is created into which the strain relief element, which is designed as a flat body, can be inserted into the chamber assigned to it.
  • This chamber can also have a flat section against which a broad side surface of the strain relief element rests.
  • the chamber preferably has two planar sections running parallel to one another, each of which is opposite a broad side surface of the strain relief element.
  • this chamber can also be closed by laser or ultrasonic welding. It is also possible to let the strain relief element run into the extruder head similar to the strands when the jacket is extruded, so that the strain relief element fills the cross section of the chamber assigned to it. It is advantageous that a lighting element created in this way can be manufactured by the meter and can be individually cut to length for special use.
  • a first section of the casing, in which the light strip is located can be separated from a second section of the casing, in which the strain relief element is located. This is done by severing at least one web that connects the two sections of the jacket to one another.
  • the lighting element shown in the drawings is used to illuminate an elevator shaft.
  • the assembly of the lighting element in an elevator shaft is on the DE 10 2014105 855 A1 and here in particular to the figure 7 or on the DE 10 2015 011 999 A1 and here in particular to the figure 1 referred.
  • the lighting element shown in the drawings can be manufactured by the meter. It has a jacket 1 made of a flexible, transparent plastic, which has a first section 1' and a second section 1''. Indentations 11 are located between the first section 1' and the second section 1''.
  • the jacket 1 has the shape a hose having a first chamber 2 arranged in the first section 1', a second chamber 6 arranged in the second section 1'' and a third chamber 10 arranged between the first chamber 2 and the second chamber 6
  • the three chambers 2, 6, 10 are each open to the front ends of the casing 1 designed as a hose.
  • the three chambers 2, 6, 10 have an elongated cross-sectional area, with the broad side surfaces of the chambers 2, 6, 10 running parallel to one another.
  • the third chamber 10, which forms a middle chamber, is separated from the first chamber 2 by a first partition wall 13 and from the second chamber 6 by a second partition wall 14.
  • the third chamber 10 has four wall sections, namely the two opposing partitions 13, 14 and two webs 9 connecting the two partitions 13, 14 to one another, the webs 9 adjoining the indentations 11.
  • the webs 9 are separating webs that are designed so thin that along the webs 9, the first section 1' can be separated from the second section 1".
  • insulating strands 12 extend all around from the plastic material of the jacket 1, with which a power supply of a light strip 3 is possible, which extends in the first chamber 2.
  • the mutually parallel strands 12 are at a distance from one another which corresponds approximately to the width of the first chamber 2, the width of the third chamber 10 or the distance between the two webs 9.
  • the light strip 3 extending in the first chamber 2 consists of a flexible conductor track which carries lamps 4 formed in regular sections of LEDs.
  • the conductor track is connected to the stranded wires 12 in regular sections by means of contact elements 19, which can be formed by wires.
  • the trace can be separated in regular sections.
  • an assembly slot 5 is produced during the production of the casing 1, which divides the wall of the first chamber 2 opposite the partition 13 into two halves, which can be bent away from each other so that a trench-shaped opening is formed through which the light strip 3 is placed in the first chamber 2 .
  • a flat underside of the light strip 3 is placed on a flat wall section of the first chamber 2 which is formed by the partition 13 .
  • the mounting slot 5 is closed. This can be done by laser welding or ultrasonic welding. Such a mounting slot show the Figures 4 and 5 .
  • a strain relief element 7 formed by a textile belt extends, which can be assigned to the first chamber 2, the second chamber 6 in a manner similar to the light strip 3.
  • the second chamber 6 can have a wall opposite the partition wall 14 with a mounting slot 8 so that the pulling element can be inserted into the chamber 6 through the mounting slot 8 .
  • the Figures 6 and 7 show the mounting slot 8.
  • both the first chamber 2 for accommodating the light strip 3 and the second chamber 6 for accommodating the strain relief element each have a mounting slot 5, 8. After the first chamber 2 has been fitted with the light strip 3 and the second chamber 6 is closed with the strain relief element 7 . According to the invention, this can be done by laser or ultrasonic welding.
  • end sections of the jacket 1 can be shortened in such a way that sections of the strain relief element 7 protrude from the jacket 1 on both sides of the jacket 1, to which fastening elements 16, 17 can be attached. It is then possible in a second step to separate the two casing sections 1′, 1′′ from one another for a certain length in the region of the two ends of the casing 1.
  • the strain relief element 7 is inserted into the second chamber 6 assigned to it only after the casing 1 has been cut to length. This can also be done here through the mounting slot 8, which can remain open.
  • supply lines 15 are connected to the strands 12, with which the strands 12 and thus the light strips 3 can be energized.
  • Each one of a large number of identical sections of the light strip 3 is connected to the two strands by means of contact elements 19 .
  • the two strands 12 can be connected directly to a 220 volt AC voltage.
  • each section of the light strip 3 has at least one rectifier.
  • the individual lamps 4 can be connected in series in such a way that the sum of the voltages dropping across them corresponds approximately to the mains voltage.
  • cables are connected directly to the strands 12 .
  • a plug is used for this purpose, which is plugged onto the end face of the casing 1 or onto the end face of the upper section 1' of the casing.
  • the first chamber 2 has a "hat-shaped" cross section.
  • a central section with a large cross-sectional area, which has an essentially rectangular outline, is adjacent to smaller sections on the two narrow sides, in which the edge of the light strip 3 extends.
  • the two ends of the strain relief element 7, which is formed by a fabric strip in the exemplary embodiment, are provided with fastening elements 16, 17 connected.
  • a fastening element 17 can be designed as a ring.
  • Another fastening element 16 can be designed as a hook.
  • a clamping element 18 is provided, which forms the function of a tension spring.
