Definitions

  • the present invention relates to the field of street and public or private areas lighting, and more precisely to a street light device for lighting streets and public or private areas.
  • the Applicant further noted that usually the devices intended for lighting, particularly those for public lighting, are not provided with specific sensors allowing to automatically detect the actual luminosity.
  • the Applicant has thus faced the problem of creating a street light device for lighting streets and public or private areas which solves the drawbacks of the prior art.
  • the invention thus relates to a street light device for lighting streets and public or private areas, comprising:
  • At least one lighting device comprising at least one lamp
  • At least one wind generator for producing alternating electric energy with a frequency varying as a function of the wind speed around the street light device
  • At least one photovoltaic generator for producing direct electric energy with a voltage varying as a function of the luminous intensity
  • thermovoltaic generator for producing direct electric energy with a voltage varying as a function of the thermal gradient
  • At least one primary electric circuit for storing electric energy produced by at least one of the said generators and transferring it to the electric grid.
  • the present invention in the abovementioned aspect, may comprise at least one of the preferred features hereinafter described.
  • the primary electric circuit comprises:
  • the lighting device comprises a plurality of LEDs.
  • the current inverter comprises a buck-boost electronic module.
  • the primary electric circuit comprises at least one accumulator battery for storing electric current produced by the wind generator and/or the photovoltaic generator and/or the thermovoltaic generator.
  • the device comprises at least one diode rectifier functionally connected with said wind generator and said at least one capacitor.
  • the device comprises:
  • thermovoltaic generator comprises at least two layers of a coating comprising nano-depositions.
  • the photovoltaic generator comprises at least two layers of a coating comprising nano-depositions.
  • FIG. 1 is a schematic perspective view of the street light device for lighting streets and public or private areas according to the present invention
  • FIG. 2 is a schematic view of the circuit for the street light device for lighting streets and public or private areas according to the present invention.
  • a street light device for lighting streets and public or private areas according to the present invention is indicated with reference numeral 100.
  • the device 100 essentially consists of at least one outer casing 3, preferably having a parallelepiped shape, at least one lighting device 4, comprising at least one lamp, at least one wind generator 5 for producing alternating electric energy with a frequency varying as a function of the wind speed around the street light device, at least one photovoltaic generator 6 for producing direct electric energy with a voltage varying as a function of the luminous intensity, at least one thermovoltaic generator 7 for producing direct electric energy with a voltage varying as a function of the thermal gradient, at least one connection 8 to an electric grid, at least one primary electric circuit 9 for storing the electric energy produced by at least one of said generators and transferring it to the electric grid.

  • at least one wind generator 5 for producing alternating electric energy with a frequency varying as a function of the wind speed around the street light device
  • at least one photovoltaic generator 6 for producing direct electric energy with a voltage varying as a function of the luminous intensity
  • the street light device 100 as a lighting device has a plurality of LEDs.
  • FIG. 1 An example of a current circuit of the street light device 00 for lighting streets and public or private areas according to the present invention is shown in figure 2.
  • the wind generator 5 is connected in series with a diode rectifier 13 for converting the energy produced by the wind generator 5 into direct current, in order to transfer it to suitable banks of capacitors 1 1 connected in series with said rectifier 13.
  • the banks of capacitors 1 1 are connected in parallel with the photovoltaic generator 6 and the thermovoltaic generator 7.
  • the banks of capacitors 1 1 are in turn connected with a Buck-Boost electronic module 12. Downstream of the said Back-Boost 12 there are a plurality of accumulator batteries 14 connected in series with each other and in parallel with an inverter 10 for supplying current to the grid by means of a suitable connection 8.
  • the Buck-Boost 12 has the task of adapting the voltage value for charging one or more accumulator batteries and/or properly power the inverter 10, which provides for the supply of the electric energy to be used by the LEDs and to be transferred to the grid according to the specific standards, e.g. single- phase, 230 V - 50 Hz, or three-phase, 3 x 380 V - 50 Hz.
  • the Buck-Boost module 12 is essential for allowing even small amounts of energy to be exploited.
  • the voltage delivered by the kinetic generator must necessarily be raised (by the Boost) to the minimum value required by the single-phase or three-phase inverter.
  • thermovoltaic generator 7 and the photovoltaic generator 6 Operating conditions similar to those of the kinetic generator may also occur for the static generators, i.e. the thermovoltaic generator 7 and the photovoltaic generator 6, and the Buck-Boost module 12 significantly contributes to the increase of the overall efficiency, avoiding a fruitless dispersion of "valuable" energy.
  • the conversion of all the energy is important mainly because it cools down the photovoltaic generator 6, greatly increasing also in this case the overall efficiency.
  • thermovoltaic generator 7 comprises at least two layers of a coating comprising nano-depositions.
  • the thermovoltaic generator 7 is made, on the outer surface of the casing 3 of the street light device 100 or of the kinetic generator 5, by means of a plurality of nano-depositions, each reaching, as non-limiting example, about 100 nm.
  • said depositions are iterated until a total thickness of about 0,006 - 0,007 mm is reached.
  • the mentioned value may be increased or decreased as a function of the amount of energy and of the coated surface.
  • Said thickness also affects the production cost, therefore it will be determined based on the kind of application, taking into account the surface extension and the thermal gradient.
  • a street light placed at a height of 20 m or more, and provided with a plurality of lighting units, will have significant dimensions and thus a large outer surface; in this case the thickness of the nano-deposition may be smaller compared to a street light device placed in a built-up area at a height of about 6 m.
  • the photovoltaic generator comprises at least two layers of a coating comprising nano-depositions.
  • the street light device 100 for lighting streets and public or private areas further comprises at least one ambient sensor, at least one microcontroller, and at least one transceiver board.
  • Each street light device 100 is provided with a microcontroller for collecting and transmitting data detected by the different "ambient" sensors as well as data about the overall operating condition of the unit.
  • the microcontroller controls a transceiver board, preferably in a wireless mode (electric cables in a power line system can also be used), by means of which the individual street light device communicates with a computer directly and/or through other street light devices 100.
  • each individual street light device 100 (possibly provided also with a microcamera) transmits any variation detected by the different sensors, continuously updating the condition in the surrounding area.
  • the street light devices are individually coded and it is thus easy to effectively and promptly monitor different areas according to predetermined partitions, which, in any case, can be enlarged or restricted at any time with great flexibility.
  • the individual street lamp device also constantly communicates any variation regarding the specific operating condition of each of its devices.
  • the street light device begins to switch on or off gradually and automatically, based on a luminosity threshold predetermined according to the local norms.
  • the data and actual times are detected and transmitted to the dedicated computer, continuously updating the status.
  • the individual circuits are surveyed and any variation of the operating condition of a circuit is immediately transmitted.
  • the actual consumption of energy taken from the grid is continuously transmitted as well as the actual production of energy injected into the grid.
  • the same transmission board transfers possible control signals directed to one or more street lights, e.g. the switching on or off of the "lamp", the increase or reduction of the lighting intensity or the switching on or off of the generator, etc.
  • the monitoring can be "customized” and, according to the specific needs, it will be able to provide just a technical survey function or also an actual security surveillance on-line with police, hospitals, etc.
