Definitions

• the present invention refers to the technical field of sound-resistant and/or sound-absorbent noise barrier.
• it refers to a new type of acoustic reducer able to be installed on the barrier and made in such a way to feed the lighting plants in general, particularly the lighting plants integrated to the barrier and/or those relative to the road condition infrastructure.
• the illumination obviously has to be fed by- opportune electric power and this implies the necessity to realize, at the same time or after the assemblage of the barrier, both the opportune cabling of the cables and the connection of the different power plants. It is clear how all this implies big additional cost for the assemblage and project, over to the elevated costs of electric consumption. The problem results more severe in the case where the barrier result to be destined where there is no electrical line. In this case it is necessary to have the installation of plants and the realization of the entire power line at the same time of the assemblage of the barrier, the whole with clear additional costs and time of realization.
• the optimal angle of incidence of the beams of light results to be of about thirty degrees respect to the absorbing surface of the same panel, in order that this could function with highest efficiency.
• the predisposition of the panels in correspondence of the wall of the panel makes highly variable, and thus hardly controllable, such inclination.
• the positioning of the panels is indeed unavoidably influenced by the variation of the alignment of the route along which it is built the barrier, determining these continuing angle variation that are hardly settable and predictable. It is then clear how in such case it is hard to use the entire paneling with the highest efficiency, causing an insufficient and not reliable power supply to the light plants.
• a further problem refers to the light reflection, phenomenon that is common to all the vitreous bodies with reflecting nature. It is clear how a predisposition of the panels in correspondence of the wall of the barrier realizes a wide reflecting surface predisposed at the height of the roadway, causing consequently blare to the drivers with clear severe consequences of accidents.
• the potential impacts of the vehicles can, other than having severe consequences for the safety of the people, cause continuous and frequent breaking of the barrier, the whole with elevated maintenance costs and uneasiness caused by the temporary non functioning of the illumination.
• the aim of the present invention to give a traffic sound barrier that allows to feed lighting plants, as the common lamps suitable for the barrier or the road infrastructures, without having necessarily to comprise expensive predispositions of cables and/or power plants and sustain expensive power consumption.
• the aim of the present invention to give a sound barrier supplied with photovoltaic power panels but configured in such a way to optimise their efficiency independently from the traffic route on which the same barrier is built on and limiting at the same time the risks of light reflection and consequently of glare.
• a specific acoustic reducer suitable to be predisposed in use in correspondence of the top of a sound barrier 1 delimiting an area in general or a transition course and characterized by the fact that is configured in such a way to comprise at least a photovoltaic panel 6.
• the acoustic reducer 3 comprises a supporting surface 5 predisposed in correspondence of its substantially plane top, in such a way to allow to place on it the photovoltaic panel 6.
• the photovoltaic panel result to be internally lied on the supporting surface 5 in a way that its absorbing surface 6' result to be facing upwards.
• the photovoltaic panel can be placed according to a predetermined inclination respect to said supporting surface 5 in such a manner that the absorbing surface 6' of the panel results to be facing towards a direction of greatest incidence of the light flux.
• the photovoltaic panel is firmly connected to the upper supporting surface 5 through opportune junction means.
• Advanced technical solution can then comprise means to change automatically the inclination of the panel respect to the supporting surface in relation to the sun' s position.
• a sound barrier suitable to delimitate an area in general or a transit course and comprising:
• the photovoltaic panel (6) is placed at the top of said reducer (3) in such a way that it can be oriented according to a direction of greatest incidence of the light flux independently from the orientation of the barrier.
• the acoustic reducer comprises a supporting surface (5) predisposed in correspondence of its substantially plane top, in such a way to allow to place on it the photovoltaic panel .
• FIG. 3 represents in view a detail of the top of the barrier comprising the acoustic reducer according to the invention
• FIG. 4 shows a view in detail of the sole acoustic reducer comprising a lighting lamp
• FIG. 5 and figure 6 show two views of the acoustic reducer installed on the barrier and supplied with a photovoltaic barrier predisposed according to a predetermined inclination angle respect to its supporting plane;
• a sound barrier 1 comprises generally a plurality of panels 2 overlapped on each other according to a predefined height and depending on the specific requirements of acoustic isolation of the attributed area.
• the barrier gets developed thus in height, other than in length, starting from common supporting elements 9 able to sustain it and to allow its installation in loco along the route.
• the figure 1 shows a common supporting base 9.
• an acoustic or noise reducer 3 In correspondence of the top of the barrier is commonly placed an acoustic or noise reducer 3.
• the reducer has the function of proclaiming the performances of the same barrier by acting on the acoustic energy and damping the secondary wave front that gets extended over the barrier. Such effect gets translated into a reduction of the acoustic pressure field behind the same barrier.
• acoustic reducers of different geometries (for example hexagonal, circular or triangular) that facilitate and improve the acoustic damping along to the use of updated materials.
• damping notches 4 of the sound are commonly realized.
• the invention comprises, in a possible realization pattern, an acoustic reducer 3 comprising a photovoltaic panel 6.
• the reducer is configured in such a way to comprise a supporting surface 5 placed in correspondence of its top and suitable to receive the photovoltaic panel 6 (or anyway a number of panels that cover a part or its entire length) .
• the active part 3' (or rather the functional part of the reducer destined when used to be facing towards the noise) is configured with variable geometries according to the needs, while the upper part facing upwards (or rather the supporting surface 5) is realized substantially plane and such to place on it the panel.
• the detail solution proposed in figure 3 comprise, for example, a supporting surface 5 of rectangular shape.
• FIG. 6 represents -a vertical plane 10 of containment of the panel and protruding from the back edge of the supporting base 5.
• a supporting leg 11 supports the panel into the inclined configuration.

• the proposed solutions represent simple static positioning of the panel but, opportune means can be comprised in such a way to eventually change the inclination of the panel in relation to the time and thus to the solar positioning.

• connection means as for example gluing, bolts or similar.
• noise reducers that have already integrated the photovoltaic panels, reducing this way the assemblage costs .
