Description

[Technical Field]

[0001] The present invention relates to a ventilated multi-layer dynamic digital filter for a photovoltaic panel, and more particularly to a filter having a digital screen that performs filtering and aesthetic functions, and to a panel having a photovoltaic surface overlying the screen.

[0002] To date, transparent or translucent LED digital screens are known which are configured for installation, for example, in stores or display areas, and which, since their construction is less complex than that of conventional screens, allow for saving display and advertising space, and allow for the transmission of static or dynamic graphic representations, while at the same time allowing the viewer to see beyond the display and allowing light to pass through the display.

[0003] However, the solutions known in the art suffer from the drawback that such screens are only operable under certain temperature conditions, since they comprise electrical and electronic components that are susceptible to damage.

[0004] It is also known that the widespread installation of advertising structures using photovoltaic technology to generate the electrical energy required to illuminate the billboard at night or to power the electromechanical actuators of the billboard, thereby enabling it to operate, makes it unnecessary to lay cables and connect them to the public transmission network, thereby reducing the environmental impact of the installation.

[0005] Nevertheless, the above known solutions suffer from problems with high aesthetic impact, as well as problems with degradation of the photovoltaic surface due to the effects of UV rays and heat affecting the lifespan of the silicon and other elements that make up the photovoltaic surface, and also from architectural, historical and aesthetic constraints that make it impossible to use such solutions in many areas.

[0006] One of the objects of the present invention is to overcome the above problems by providing a ventilated multi-layer dynamic digital filter for photovoltaic panels that is capable of reproducing images with any kind of texture or pattern, thereby allowing for a reduced aesthetic impact through better integration with the application context (buildings and other applications).

[0007] Another object of the digital filter of the present invention is to extend the life of photovoltaic panels by reducing the harmful effects of ultraviolet radiation on the photovoltaic panels through appropriate shielding methods.

[0008] A further object of the invention is to improve the efficiency of photovoltaic panels by ventilation, which prevents ice formation and at the same time reduces the risk of overheating of the photovoltaic panels by dissipating heat, ensuring a constant temperature, which has a beneficial effect on the light transmittance and therefore on the overall electrical efficiency of the panels.

[0009] Another object of the present invention is to provide a ventilated multi-layer dynamic digital filter for photovoltaic panels that is robust and durable, facilitates maintenance, and can withstand high loads, allowing it to be located on the roof or at ground level, providing installation flexibility.

[0010] The above objects, as well as other aims and advantages of the present invention, will become clear in the light of the following description, and are realized through a ventilated multi-layer dynamic digital filter for photovoltaic panels as set forth in the independent claims. Some preferred embodiments and non-obvious variations of the invention are set forth in the dependent claims. It is to be understood that all appended claims are an integral part of the present invention.

[0011] It will be immediately apparent that countless variations and modifications (e.g., variations and modifications in shape, size, arrangement and parts having equivalent functions) may be made to the subject matter described herein without departing from the scope of protection of the present invention as set forth in the appended claims. [Brief explanation of the drawings]

[0012] The invention will now be described in detail through preferred embodiments thereof, given by way of non-limiting example only with reference to the accompanying drawings, in which: [Figure 1] 1 shows a perspective view of a ventilated multi-layer dynamic digital filter for a photovoltaic panel according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] Referring to FIG. 1, a ventilated multi-layer dynamic digital filter 10 for a photovoltaic panel according to the present invention comprises a front panel 11 having an LED grid or a series of parallel LEDs, a middle panel 12 having a photovoltaic surface, and a rear panel 13, said panels 11, 12, 13 indirectly overlapping each other.

[0014] Preferably, the front panel 11 comprises a translucent LED screen having an LED grid or a series of parallel LEDs, and the empty spaces in the LED grid or between the series of LEDs are configured to allow light to pass through the front panel 11 so that the light strikes the photovoltaic surface of the intermediate panel 12 without interfering with the perception of the image reproduced on the front panel 11 as complete and clear, and the translucency and / or transparency is between 30% and 95%. Specifically, the percentage ratio between the above-mentioned empty spaces and the space occupied by the LEDs of the translucent LED screen is preferably between 30% and 95%.

[0015] Preferably, the multi-layer dynamic digital filter 10 includes frames 21, 22, and 23 disposed around the periphery of each panel 11, 12, and 13, with the frame 21 of the front panel 11 contacting the frame 22 of the middle panel 12, which in turn contacts the frame 23 of the rear panel 13 to create gaps between the panels that allow heat to circulate within the multi-layer dynamic digital filter 10 to prevent both overheating and ice formation. Preferably, the frames 21, 22, and 23 of the front panel 11 that contact each other are connected by hinges, which allows the multi-layer dynamic digital filter 10 to be opened like a book to inspect the gaps between the panels 11, 12, and 13 (e.g., for cleaning and maintenance).

[0016] The front panel 11 is made of a shatterproof transparent material, which makes the structure of the ventilated multi-layer dynamic digital filter 10 robust and resistant to atmospheric contamination events or effects, and to very high loads (e.g., for roof or ground installations). Specifically, with regard to the construction sector, the multi-layer dynamic digital filter 10 of the present invention can be used to assemble prefabricated houses and for the exterior cladding of the facade and / or roof, allowing for changing the cladding pattern / texture and improving the energy efficiency of the building.

[0017] The ventilated multi-layer dynamic digital filter 10 for photovoltaic panels according to the present invention provides the following advantages: -A translucent LED screen allows light to pass through, which is converted into energy by an intermediate photovoltaic panel. The energy so produced can be used to reduce the energy consumption of the screen or stored for other uses. The LED grid provides a protective structure for the intermediate photovoltaic panel, which reduces the amount of UV radiation hitting the panel, extending the life of the silicon and other components of the panel and reducing their temperature, making the panel more efficient in operation. -The air chambers provided in the gaps allow heat to dissipate, reducing the temperature inside the structure, making the photovoltaic panels more efficient when exposed to the sun and improving the operating conditions of the LED screens while reducing the risk of overheating. -In cold weather, heat circulating through the gap prevents ice formation and maintains a more stable operating temperature, improving the performance of digital screens.

[0018] Naturally, further modifications and variations can be made to the preferred embodiments of the invention described herein without departing from the inventive concept. In particular, it will be immediately apparent to those skilled in the art that numerous functionally equivalent variations and modifications fall within the scope of protection of the present invention, as focused by the appended claims (in the claims, any references in parentheses shall not be understood as limiting the scope of the claims themselves). Furthermore, the word "comprising" does not exclude the presence of elements and / or steps other than those recited in the claims. The article "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The mere fact that certain features are recited in dependent claims does not imply that a combination of these features cannot be used to advantage.
