Definitions

  • the invention relates to a lighting device for integration into a traffic area, in particular accessible by vehicles, consisting of a carrier profile and at least one light source, which is arranged in or below a filling of at least partially transparent filler material in the carrier profile, the carrier profile being U-shaped in cross section is formed and has two legs and a web connecting the legs.
  • Traffic areas in particular those that can be driven by vehicles, are well known. There is in particular the requirement that such traffic areas have a sufficient load-bearing capacity and are also resistant to abrasion, for example from vehicle tires.
  • the traffic areas should have a certain porosity, so that rainwater can not only be drained close to the surface, but also penetrates into the traffic areas in order to then be discharged into an area outside the traffic areas.
  • traffic areas must also be resistant to temperature fluctuations, so that the traffic areas are resistant to both low temperatures and high temperatures when exposed to direct sunlight. Traffic areas of this type are known which are formed from concrete, asphalt and / or bitumen. Basically, these traffic areas have also proven their worth insofar as the above-mentioned requirements have to be met.
  • traffic light systems can be integrated in the area of pedestrian crossings.
  • Certain areas of traffic areas can also be divided into areas by lighting devices, for example in the area of parking garages, in order to provide areas of different sizes for different vehicles. Reservations of parking areas can also be indicated by such lighting devices.
  • lighting devices for example in the area of parking garages, in order to provide areas of different sizes for different vehicles. Reservations of parking areas can also be indicated by such lighting devices.
  • generic lighting devices it is also possible to display the course of traffic areas, for example walkways, lanes or directions of travel.
  • a traffic area which consists of a base layer and a cover layer arranged above the base layer, the cover layer consisting of irregularly shaped, at least light-reflecting, but in particular also supplementary glass bodies which are permeable and optionally refracting to light rays and which are coated with a polymer or binder Resin bound.
  • an element which converts light energy into electrical energy, this element being protected from weather influences and direct contact and excessive stress in an area inside or below the top layer, but in any case above the base layer, so that in addition to the safety aspect for this Element is also guaranteed that a sufficient amount of light energy penetrates the cover layer and can reach the element, so that the light energy striking the element in this regard is sufficient for the operation of an electrical consumer.
  • a generic lighting device with at least one light-emitting diode which is at least partially embedded in a translucent solid material, this material surrounding at least the upper region of the diode.
  • the translucent solid material comprises an adhesive and solid particles with dimensions between 1 mm and 16 mm, which are suitable for refracting the light.
  • the solid material and the diode are arranged in a U-shaped profile element, a profile with a trapezoidal cross-section being inserted in this profile element, which on the one hand carries the diode and on the other hand forms a cavity within the profile element, which among other things also guides energy lines serves as a diode.
  • the solid particles are designed as glass spheres, the diodes not being covered by the glass spheres.
  • This lighting device has a number of disadvantages.
  • the design with glass balls forms a very dense packing of material, the cavities of which are then filled with synthetic resin. This basically prevents rainwater from being drained away. Especially at cold temperatures, the rainwater freezes on the surface and leads to a very smooth surface that is prone to accidents.
  • the synthetic resin can at least partially lose its connection to the glass spheres due to different thermal expansion coefficients of the materials. Rainwater can then penetrate the profile element and cause corrosion. Rainwater that has penetrated can also freeze at low temperatures and lead to further destruction of the solid material made of glass spheres and synthetic resin.
  • the diodes are also unprotected. Penetrating grit particles, for example abrasion of the road surface, can accumulate above the diode and move towards the diode when subjected to pressure, for example by vehicles, and destroy it upon contact.
  • the filling and / or the filling material is or are permeable to water and that the carrier profile has at least one opening through which water and / or other liquids can escape.
  • rainwater can diffuse through the filling and / or the filling material.
  • this has at least one opening, so that the rainwater that flows through the Filling and / or the filling material is diffused to the outside of the lighting device can escape.
  • the opening is preferably arranged in the region of the web connecting the legs.
  • the web can also be designed as a perforated plate. It is only necessary to ensure that the required load-bearing capacity of the lighting device is ensured even when vehicles are run over.
  • openings can of course also be provided in the region of the legs of the carrier profile, so that rainwater can also emerge from the carrier profile via the legs.
  • the light source is preferably designed as a diode strip and extends in particular over at least half the length of the carrier profile. This enables full-area illumination of the surface of the lighting device.
  • the diode strip can be designed in such a way that it emits light of different colors, so that, for example, the lighting device shines green in signal or red in signal and can thus be used in a traffic area as a light signaling system.
  • the colors can be controlled via a circuit.
  • the carrier profile has support elements on a surface facing away from the filling, which are preferably L, U or T-shaped.
  • the support elements are preferably arranged on the web of the support profile, so that the support profile stands up in the intended arrangement in a traffic area on the support elements.
  • the rainwater can thus flow off through the opening in the support profile and is led away in an area below the support profile without the support profile being arranged with the web or part of the legs in the precipitation profile.
  • the area below the web is thus usable as a temporary reservoir by different Compensate the runoff speeds of the rainwater. In any case, the rainwater should be drained out of the lighting device as quickly and completely as possible.
  • the support elements stand on an inner layer of the traffic area. As a rule, this layer is also permeable to water, so that the rainwater can flow off through this layer.
  • glass chippings which are bound with a binder
  • the glass chips have an uneven edge formation, so that only very small contact points are formed with neighboring chip particles, between which the binder has an adhesive effect. Accordingly, it is also an aim of the lighting device according to the invention to use as little binder as possible. On the one hand, this serves to keep the costs for the filling material low.
  • the use of a small proportion of binder has the advantage that the water permeability of the filling remains very high, so that rainwater can also diffuse very quickly through the filling or the filling material. Nevertheless, an adequate connection of the broken glass particles should be ensured, so that even driving over the lighting device does not lead to tearing out individual broken glass particles.
  • Broken clear glass which has a high level of light transmission, is used in particular as glass chips.
  • This material is also suitable for allowing sunlight to pass in the direction of the light source and, in this area, for providing additional devices, for example photovoltaic modules, which convert sunlight into electrical energy.
  • the legs of the carrier profile are angled in opposite directions at their free ends.
  • the angled ends can rest on parts of the traffic area and thus provide better pressure introduction into the traffic area.
  • the surfaces of the angled part of the legs can be used, for example, for the arrangement of photovoltaic modules in order to use them to generate electrical energy when exposed to light, which energy will be used at a later time to operate the lighting device.
  • the support profile with a plurality of openings arranged at uniform intervals, these Openings are preferably arranged in the longitudinal axis direction of the carrier profile.
  • Several rows of openings can also be arranged next to one another in the longitudinal axis direction. Furthermore, it can be provided that the transition regions of the legs in the web of the support profile are lined with profile parts with a triangular cross section, so that the rainwater is drained away in a simple manner towards the openings. In addition, such a further development prevents capillary rainwater from remaining in the webs within the carrier profile in the transition regions of the legs, which could lead to corrosion damage or frost blasting.
  • the carrier profile and / or the filling has a water permeability k f value of greater than or equal to 5.4 ⁇ 10 -5 m / s according to DIN 18 130.
  • Water permeability means the property of a layer of a building material or component to allow water to flow through open pores.
  • Water-permeable asphalt base courses that can be used for traffic areas can be installed, for example, under conventional paving slabs and slabs.
  • the above-mentioned value for the water permeability of greater than 5.0 or 5.4 x 10 -5 m / s fulfills the requirements that a proper drainage of a traffic area at 270 liters (sx ha) is possible.
  • the carrier profile preferably consists of a corrosion-resistant metal, in particular stainless steel or acrylic glass.
  • a corrosion-resistant metal in particular stainless steel or acrylic glass.
  • the load-bearing capacity of the support profile is to be interpreted by appropriate material thicknesses of the legs and the web. It must be taken into account here that a minimum compressive strength of 120 MN per m 2 must be given for traffic areas that can be driven on by vehicles.
  • the load capacity of the lighting device should be at least 3 to 5 times higher and should reach at least 60% of the pressure load capacity of a stone chip covering.
  • the filling has quartz sand as a further component.
  • Quartz sand refers to a type of sand that mainly consists of quartz grains.
  • the carrier profile can also be made of Acrylic glass are formed to allow the emission of light also on the support profile.
  • an aliphatic polyurethane is used as the binder, a one-component polyurethane in particular having proven to be suitable.
  • the filling preferably has 4 to 7% by volume, in particular 6% by volume, of binder. This proportion of binder has proven to be particularly advantageous in connection with a filling material for the filling, which is formed from particles with a maximum grain size of 10 mm.
  • the single figure shows a lighting device 1 for integration into a traffic area, not shown, which can also be driven by vehicles, for example.
  • the lighting device 1 consists of a carrier profile 2.
  • the carrier profile 2 is U-shaped in cross section and has a web 3 and two legs 4 oriented at right angles thereto.
  • the carrier profile 2 is made of stainless steel.
  • the lighting device 1 has a diode bar as the light source 5, which extends over the entire length of the carrier profile 2.
  • the light source 5 is arranged above the web 3 and a distance is provided between the light source 5 and the web 3.
  • the web 3 and the two legs 4 define a receiving space 6, in which a filling 7 made of a filling material 8 is arranged next to the light source 5.
  • the filler 8 consists of glass chippings and a binder, namely an aliphatic polyurethane, the filler 7 having 6% by volume of binder and the filler 8 having particles of clear glass with a maximum grain size of 10 mm.
  • the filling 7 and thus also the filling material 8 are arranged above the light source 5, the filling material 8 being water-permeable and translucent.
  • support elements 10 with a T-shaped cross section can also be arranged, for example between the L-shaped support elements 10.
  • the carrier profile 2 has a multiplicity of openings 11 in the region of the web 3 and openings 12 in the region of the legs 4. These openings 11, 12 serve as outlets for rainwater entering the lighting device 1. It can be seen here that the openings 12 are arranged in a region of the legs 4 directly above the connecting line to the web 3.
  • the light source 5 consists of a light band with several LEDs, which are arranged on a common carrier element.
  • the backing element is self-adhesive on the back.
  • the distance between two adjacent LEDs is approximately 16.6 mm, the LEDs having a beam angle of 120 °.
  • the carrier element has a width of 10 mm and a height of 2.5 mm.
