Definitions

  • the invention relates to a lighting device for integration in a traffic area, especially accessible by vehicles, consisting of a carrier profile and at least one light source which is arranged in or below a filling made of at least partially transparent filling 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 vehicles can drive on, are well known. There is a particular requirement here that such traffic areas have a sufficient load-bearing capacity and, moreover, 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 off near the surface, but also penetrate 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 as resistant as possible to both low temperatures and high temperatures in direct sunlight.
  • Such traffic areas which are made of concrete, asphalt and / or bitumen are known. Basically, these traffic areas have also proven their worth, insofar as the above-mentioned requirements have to be met.
  • traffic lights can be integrated in the area of pedestrian crossings.
  • Certain areas of traffic areas can also be subdivided into areas as required 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 spaces can also be displayed by such lighting devices.
  • 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 additionally permeable to light rays and optionally refractive glass bodies, which are coated with a binder of the polymer or Resin are bound.
  • an element which converts light energy into electrical energy, this element being protected from the weather and direct contact and excessive load in an area within or below the top layer, but in any case above the base layer, so that in addition to the safety aspect for this Element also ensures that a sufficient amount of light energy penetrates the cover layer and can reach the element, so that the light energy incident on the element in this regard is sufficient for the operation of an electrical consumer.
  • This prior art cites, for example, light sources as electrical consumers that can be arranged on the base layer and next to the top layer, the light rays of which are emitted into the top layer in the direction of a surface normal of the top layer and / or parallel to a surface of the top layer.
  • 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 sheet metal with a trapezoidal cross-section being additionally inserted into 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 serves to guide power lines serves to the 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 spheres forms a very tight packing of material, the cavities of which are then filled with synthetic resin. This basically avoids the discharge of rainwater. Precipitation water freezes on the surface, especially at cold temperatures, 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 the different coefficients of thermal expansion of the materials. Rainwater can then penetrate the profile element and cause corrosion. In addition, rainwater that has penetrated can freeze at low temperatures and lead to further destruction of the solid material made of glass spheres and synthetic resin.
  • the diodes are unprotected.
  • Penetrating grit particles for example abrasion from the road surface, can accumulate above the diode and move in the direction of the diode under pressure, for example from vehicles, and destroy it upon contact.
  • the filling and / or the filling material is or are water-permeable and that the carrier profile has at least one opening through which water and / or other liquids can exit.
  • 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 has diffused to escape outside the lighting device.
  • the opening is preferably arranged in the area 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 guaranteed even when vehicles are driven over it.
  • openings can also be provided in the area of the legs of the support profile, so that rainwater can also escape from the support 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 support 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 lights up in signal green or in signal red and can thus be used as a traffic light system in a traffic area.
  • 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 carrier profile so that the carrier profile rests on the support elements in the intended arrangement in a traffic area.
  • the rainwater can thus flow off via the opening in the carrier profile and is led away in an area below the carrier profile without the carrier profile with the web or part of the legs being arranged in the precipitation profile.
  • the area below the web can thus be used as a temporary reservoir for different purposes To compensate for the runoff velocities of the rainwater. In any case, the rainwater can be drained as quickly and completely as possible from the lighting device.
  • the support elements stand on an inner layer of the traffic area. As a rule, this layer is also permeable to water, so that rainwater can flow off through this layer.
  • broken glass which is bound with a binding agent
  • the glass chippings have uneven edges so that only very small points of contact with neighboring chippings are formed, between which the binding agent has an adhesive effect. Accordingly, it is also an aim of the lighting device according to the invention to use as little binding agent 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 filler material. Nevertheless, a sufficient connection of the broken glass particles should be ensured so that even driving over the lighting device does not lead to individual broken glass particles being torn out.
  • broken clear glass which has a high level of light permeability, is used as the broken glass.
  • This material is also suitable for allowing sunlight to pass in the direction of the light source and, in this area, to provide additional equipment, for example photovoltaic modules, which convert sunlight into electrical energy.
  • the legs of the support profile are angled at their free ends in opposite directions.
  • the angled ends can rest on parts of the traffic area and thus provide a better introduction of pressure 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 light is irradiated, which is used at a later point in time to operate the lighting device.
  • the carrier profile it has proven to be advantageous to design the carrier profile with a plurality of openings arranged at regular intervals, these openings Openings are preferably arranged in the longitudinal axis direction of the support profile.
  • Several rows of openings can also be arranged next to one another in the direction of the longitudinal axis. Furthermore, it can be provided that the transition areas 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 off in a simple manner in the direction of the openings. In addition, such a development prevents that in the transition areas of the legs in the webs within the carrier profile, in particular capillary rainwater remains, which could lead to corrosion damage or frost bursts.
  • 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 is the property of a layer of a building material or component to allow water to flow through open pores.
  • Water-permeable asphalt base layers that are used for traffic areas can be installed under conventional paving and paving, for example.
  • the above-mentioned value for water permeability of greater than 5.0 or 5.4 x 10 -5 m / s fulfills the requirements that proper drainage of a traffic area of 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 support profile is also the possibility of producing the support profile from aluminum, whereby it must of course be taken into account that aluminum can also be exposed to corrosion, especially in connection with salts.
  • the load-bearing capacity of the support profile is to be interpreted by corresponding material thicknesses of the legs and the web. It must be taken into account here that traffic areas that can be driven on by vehicles must have a minimum compressive strength of 120 MN per m 2.
  • the load capacity of the lighting device should be at least 3 to 5 times higher and reach at least 60% of the pressure load capacity of a stone chippings surface.
  • the filling has quartz sand as a further component.
  • Quartz sand is a type of sand that consists predominantly of quartz grains.
  • the carrier profile can alternatively also be made from Acrylic glass can be formed in order to enable the emission of light via the carrier 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 filler 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 in more detail) which, for example, can also be driven on by vehicles.
  • 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 aligned at right angles thereto.
  • the carrier profile 2 is made of stainless steel.
  • the lighting device 1 has a diode strip 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, in addition to the light source 5, a filling 7 made of a filling material 8 is arranged.
  • the filling material 8 consists of glass chippings and a binding agent, namely an aliphatic polyurethane, the filling 7 having 6% by volume of binding agent and the filling material 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 permeable to water and light.
  • two support elements 10 with an L-shaped cross section are arranged on the outside.
  • support elements 10 with a T-shaped cross-section can also be arranged, for example between the L-shaped support elements 10. It is also possible to design the support elements 10 in a U-shaped cross-section in order to provide a larger connecting surface between the support elements 10 and the carrier profile 2.
  • the carrier profile 2 has a large number of openings 11 in the area of the web 3 and openings 12 in the area of the legs 4. These openings 11, 12 serve as outlets for rainwater penetrating into 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 back of the carrier element is self-adhesive.
  • the distance between two adjacent LEDs is approx. 16.6 mm, with the LEDs having a beam angle of 120 °.
  • the carrier element has a width of 10 mm and a height of 2.5 mm.
