Description

Technical Field

[0001] This invention relates to a ventilated multilayer dynamic digital filter for a photovoltaic panel, particularly a filter comprising a digital screen that performs filtering and aesthetic functions, and to a panel having a photovoltaic surface overlapping the screen. Background Technology

[0002] Transparent or semi-transparent LED digital screens are known to date, which are configured for installation in, for example, shops or display areas. Because this structure is simpler than traditional screens, it allows for saving display and advertising space and allows for the conveying of static or dynamic graphic representations, while allowing viewers to see things outside the display and light passing through.

[0003] However, the solutions known in the art have the following drawbacks: such screens can only operate under specific temperature conditions because they contain easily damaged electrical and electronic components.

[0004] It is also known that widely distributed and installed advertising structures employ photovoltaic technology to generate the electricity needed for nighttime illumination billboards, or power their electromechanical actuators to operate, thereby avoiding the need to lay cables and connect to the public power grid, and thus reducing the environmental impact of the installation.

[0005] However, the known solutions have problems with the degradation of photovoltaic surfaces and high aesthetic impact due to the effects of ultraviolet radiation and heat on the lifespan of silicon and other elements that make up the photovoltaic surface, and they may not be usable in many fields due to architectural, historical and landscape limitations. Summary of the Invention

[0006] One object of the present invention is to overcome these problems by providing a ventilated multilayer dynamic digital filter for photovoltaic panels, which allows for reduced aesthetic impact by better integration into the application environment (architecture and other applications) due to its ability to reproduce images with any type of texture or pattern.

[0007] Another objective of the digital filter of this invention is to reduce the adverse effects of ultraviolet radiation on photovoltaic panels through proper shielding, thereby extending the lifespan of photovoltaic panels.

[0008] Another objective of this invention is to improve the efficiency of photovoltaic panels through ventilation, reduce the risk of overheating of photovoltaic panels by heat dissipation while preventing icing, thereby ensuring temperature balance, resulting in a beneficial effect on optical transmittance, and thus a beneficial effect on the overall electrical efficiency of the panel.

[0009] Another object of the present invention is to provide a ventilated multilayer dynamic digital filter for photovoltaic panels that is robust, easy to maintain, and offers installation flexibility because it can withstand high loads and can therefore be placed on a roof or on the ground.

[0010] The above-mentioned objects, as well as other objectives and advantages of the present invention, will become clear from the following description, achieved by a ventilated multilayer dynamic digital filter for photovoltaic panels as described in the independent claims. Some preferred embodiments and non-obvious variations of the invention are set forth in the dependent claims.

[0011] It should be understood that all appended claims are integral parts of this invention.

[0012] It is obvious that many variations and modifications can be made to the content described herein (e.g., in terms of shape, size, arrangement, and components with equivalent functions) without departing from the scope of protection of the invention as set forth in the appended claims. Attached Figure Description

[0013] The present invention will be described in detail below by way of preferred embodiments, which are provided by way of non-limiting example only with reference to the accompanying drawings, wherein:

[0014] - Figure 1 A perspective view of a ventilated multilayer dynamic digital filter for a photovoltaic panel according to the present invention is shown. Detailed Implementation

[0015] Referring to the accompanying drawings, the ventilated multilayer dynamic digital filter 10 for photovoltaic panels according to the present invention includes a front panel 11, a middle panel 12 and a rear panel 13. The front panel 11 includes an LED grid or a series of parallel LEDs, and the middle panel 12 includes a photovoltaic surface. The panels 11, 12 and 13 overlap each other indirectly.

[0016] Preferably, the front panel 11 includes a translucent LED screen comprising an LED grid or a series of parallel LEDs. The blank spaces within the LED grid or between these LEDs are configured to allow light to pass through the front panel, such that it impacts the photovoltaic surface of the intermediate panel 12 without obstructing the perception of the image reproduced on the front panel 11 as complete and clear. The level of translucency and / or transparency is between 30% and 95%. Specifically, the percentage of blank space in the translucent LED screen relative to the space occupied by the LEDs is preferably between 30% and 95%.

[0017] Preferably, the multi-layer dynamic digital filter 10 includes frames 21, 22, and 23 located around the periphery of each panel 11, 12, and 13. Frame 21 of the front panel 11 contacts frame 22 of the middle panel 12, and frame 22 in turn contacts frame 23 of the rear panel 13, creating a gap between the panels. This gap is configured to allow heat to circulate within the multi-layer dynamic digital filter 10, thereby preventing overheating and icing. Preferably, the contacting frames 21, 22, and 23 of the front panel 11 are hinged, allowing it to be opened like a book to inspect the gap between the panels 11, 12, and 13, for example, for cleaning and maintenance purposes.

[0018] The front panel 11 may be made of a shatterproof transparent material to make the structure of the ventilated multi-layer dynamic digital filter 10 robust and resistant to atmospheric events or destructive behavior and particularly high loads, for example, for roof or ground mounting. In particular, in the field of construction, the multi-layer dynamic digital filter 10 of the present invention can be used for assembling prefabricated houses and for external cladding of exterior walls and / or roofs, and has the potential to change the pattern / texture of the cladding and improve the energy efficiency of the building.

[0019] The ventilated multilayer dynamic digital filter 10 for photovoltaic panels according to the present invention has the following advantages:

[0020] - The semi-transparent LED screen allows light to pass through, and the light is converted into energy by the photovoltaic panel in the middle;

[0021] - The energy generated can be used to reduce the screen's energy consumption, or stored for other purposes;

[0022] - The LED grid provides protection for the central photovoltaic panel, extending the lifespan of the panel's silicon and other components by minimizing UV impact and reducing their temperature, thus allowing the panel to operate more efficiently.

[0023] - The air chambers set in the gaps reduce the temperature inside the structure by dissipating heat, thereby making the photovoltaic panel more efficient when exposed to sunlight and improving the working conditions of the LED screen, while reducing the risk of overheating;

[0024] - In cold seasons, the heat circulating within the gaps prevents freezing and improves the performance of digital screens by maintaining a more stable operating temperature.

[0025] The preferred embodiments of the invention described herein are of course subject to further modifications and variations without departing from the spirit of the invention. In particular, those skilled in the art will understand that many functionally equivalent variations and modifications will fall within the scope of protection of the invention as emphasized in the appended claims, wherein any references within parentheses should not be construed as limiting the claims themselves. Furthermore, the word "comprising" should not exclude the presence of elements and / or steps other than those listed in the claims. The procals "a" or "an" preceding an element do not exclude the presence of a plurality of such elements. The simple fact that some features are mentioned in the dependent claims does not mean that an advantage cannot be obtained by utilizing a combination of these features.
