Definitions

  • the invention relates to a guidance system, in particular a guidance system for marking escape routes, comprising a row of light emitting diodes.
  • Markings of escape routes in the event of a fire are to be arranged close to the ground, so that they are visible even if the escape routes are filled with smoke.
  • Guidance systems having markings made of a photoluminescent material, with which the course of an escape route can be marked. By shaping the markings as arrows, a prescribed escape direction may also be indicated.
  • US 5 276 591 A describes an illuminated sign system having a graphic panel that is illuminated by light from LEDs which is injected into the edge of the graphic panel.
  • the LEDs are arranged on a printed circuit board.
  • the printed circuit board extends across a space between opposing inner side walls of the housing. Opposite edges of the printed circuit board are held in respective grooves in the side walls of the housing.
  • WO 2010/068298 A1 describes an emergency route illumination system and method using linear illuminators parallel to and near the floor of an interior room or hallway to provide floor-level identification and illumination of an exit route.
  • a groove on the top edge of a baseboard secures portions of a linear illuminator in place relative to the baseboard.
  • WO 98/10219 A1 describes an integrally formed single piece light strip having no internal voids, comprising bus elements for operative connection to a power source. At least one LED is mounted on a top surface of a substrate strip and connected to a printed circuit that is in electrical contact with the bus elements. An extruded plastic material completely encapsulates the bus elements, the substrate strip and the LED to thereby provide a protective barrier and thereby make the light strip impervious to moisture.
  • the LED strip is mounted in a protective track formed from aluminum and may be flush mounted in areas such as an airport taxiway or an automobile highway.
  • WO 2006/109911 A1 describes an emergency guide unit having LED arrays which receives a control signal and emits and indicates an escape direction under the control of a controller.
  • the escape guide is installed on the floor of a passage in a subway, with a transparent upper cover protruding from the floor.
  • US 6 241 369 B1 describes a light fixture that includes a housing and a mounting base having a connector. A lens panel, such as an exit sign, extends from the bottom of the fixture.
  • DE 101 28 689 A1 describes a floor illumination unit comprising LEDs arranged in a groove of the floor and covered by a glass or plastic plate. It is an object of the invention to provide a guidance system that makes possible an inconspicuous appearance, and nevertheless is very easily visible in an emergency situation. According to the invention, this object is achieved by a guidance system having a flat substrate strip that is arranged in a groove in a floor, and which comprises a front side that faces a side wall of the groove and that is equipped with a row of light emitting diodes, wherein the substrate strip is arranged on edge in the groove, and wherein the groove comprises a light-transmitting cover, which closes the groove at the top.
  • the guidance system is a guidance system that is integratable into the ground or is integrated in the ground.
  • a flat substrate strip is arranged on edge in the groove in the floor, for example a floor joint, a very small required space results. Therefore, for example, the substrate strip with the light emitting diodes can be laid in a joint between floor tiles.
  • the guidance system may be subsequently installed in a existing floor. Furthermore, because of the small dimensions, an inconspicuous appearance of the guidance system results. For example, an architectural design of an indoor room of a building may remain unimpaired. It is also advantageous that, due to the light emitting diodes, a good visibility of the guidance system can be ensured also in the event of a fire.
  • the guidance system may be adapted for operating the row of light emitting diodes as a running light. Thereby, for example even depending on an identified situation of danger, a suitable escape direction can be marked.
  • the groove comprises a floor joint, in particular a joint between floor tiles.
  • Fig. 1 schematically shows a cross sectional view of a groove 10 in a floor, which groove comprises a floor joint between two floor tiles 12.
  • the groove 10 has a roughly rectangular cross section, is defined at its sides by the edges of the floor tiles 12 in an upper zone, and is defined at its sides as well as in a downward direction by an underlying ground 14 in a lower zone.
  • the groove 10 has a height of at least one or two centimeters, and has a width of less than 10 millimeters, for example 5 mm. Different from the illustration of Fig. 1 , the height of the groove 10 may also be limited to the vertical range of the floor tiles 12.
  • a flat substrate strip 16 in the form of a flexible, strip-shaped printed circuit is arranged standing upright in the groove 10.
  • the substrate strip 16 comprises a reinforcing layer 18 for increasing the tensile strength.
  • the substrate strip 16 comprises at a back side the reinforcing layer 18 in the form of a metal strip.
  • LEDs light emitting diodes
  • the front side of the substrate strip 16 faces a side wall of the groove 10.
  • the substrate strip 16 standing on edge is vertically aligned. However, it may also be inclined with respect to the vertical direction.
  • the substrate strip 16 carries the light emitting diodes 20 as well as strip conductors, and, optionally, electronic circuit sections for operating the light emitting diodes 20.
  • the light emitting diodes 20 are adapted for radiating light in an angular range that extends over more than 90°, for example over 170°, transverse to the longitudinal direction of the substrate strip 16.
  • a respective main radiation direction corresponds to a surface normal of the front side of the substrate strip 16 in the region of the respective light emitting diode 20.
  • the main radiation direction is directed against the lateral boundary of the groove 10.
  • the groove 10 is at least partially filled with a casting material 22 that is light-transmitting or translucent.
  • the casting material 22 closes the groove 10 at the top and, thus, forms a top cover.
  • the casting material 22 is flush with a top edge of the floor tiles 12.
  • the casting material 22 is optically clear, i.e. transparent.
  • the casting material 22 may be coloured.
  • the casting material 22 forms a light-conducting structure for conducting light from the light emitting diodes 20 to the top surface of the casting material 22 and, thereby, improve the visibility of the light radiated from the light emitting diodes 20.
  • the casting material 22 also secures the substrate strip 16 with the light emitting diodes 20 in the groove 10.
  • the casting material 22 forms a protection for the light emitting diodes 20 and the substrate strip 16 against contamination and against the penetration of moisture.
  • the casting material 22 may consist of a polymeric material or may comprise a polymeric material as an essential constituent, for example polyurethane.
  • the casting material 22 may be composed of multiple sections.
  • a first section of the casting material 22 may form a casing for the light emitting diodes 20, optionally including the substrate strip 16, and a second section of the casting material 22, which may have a different material structure, may form a top ending of the groove 10, i.e. a cover.
  • the substrate strip 16 with the casing being formed by the first section of the casting material 22 may be inserted into the groove 10 and then be sealed by further casting material, which then forms the second section of the casting material 22.
  • Fig. 2 shows a top view of a section of a guidance system that is integratable into the ground, having the structure shown in Fig. 1 .
  • the substrate strip 16 with the light emitting diodes 20 extends along the groove 10, which in turn extends at the position of a floor joint between respective floor tiles 12 facing each other.
  • the groove may also be introduced into the ground at other positions and may, for example, run across a floor tile 12 and split the same.
  • the latter may also follow an angular course of the groove 10, because due to the arrangement of the substrate strip 16 standing on edge, the bending stress is much lower than e.g. in the case of a flat, horizontal arrangement of a substrate strip.
  • Fig. 3 shows an embodiment, wherein the substrate strip 16 with the light emitting diodes 20 is arranged in a groove 23 of a metal section 24 having, for example, a U-shaped cross-section.
  • the metal section 24 is, in turn, arranged in the groove 10 in the ground.
  • the metal section 24 is an aluminium profile. The open side of the metal section 24 is facing upwards in the example.
  • the metal section 24 is covered on the top by the casting material 22.

  • the casting material 22 may be composed of multiple sections. For example, a first section of the casting material 22 may be disposed in the interior of the metal section 24, and a second section of the casting material 22 that has, for example, a different material structure, may form a top ending of the groove 10, i.e. a cover.
  • the substrate strip 16, which is encapsulated together with the light emitting diodes 20 by the first section of the casting material 22 in the metal section 24, may, for example, be arranged in the groove 10 and may there be sealed by further casting material, which then forms the second section of the casting material 22.
  • the metal section 24 Due to a metallic surface of the metal section 24, for example a smooth surface, light from the light emitting diodes 20 may be scattered or reflected towards the top side of the groove 10.
  • the metal section 24 may comprise one or more reflective inner faces.
  • Fig. 4 shows a further embodiment, wherein the light emitting diodes 20 are encapsulated by a first casting material 22', and wherein the substrate strip 16 together with the first casting material 22' is arranged in the groove 10 and is covered by a second casting material 22".
