Description

[Technical field]

[0001] The present invention relates to a solar power system that receives a driving power supply from solar power generation and displays an image in a front direction. [Background technology]

[0002] Renewable energy is recognized as a clean energy source that does not emit hazardous substances such as pollutants, global warming, or radioactivity, and does not require reprocessing facilities. There are various types of renewable energy sources, such as wind, wave, solar, and geothermal, but solar power is the most widely used because it is the most convenient in terms of scale, installation, and operation.

[0003] Recently, systems such as carbon emission rights have been implemented worldwide to reduce greenhouse gas emissions, and new and renewable energy sources are considered to be even more important. As a result, various methods to increase the amount of power generated by new and renewable energy sources are being actively attempted. In particular, such attempts have focused on solar power, which is more convenient than other power generation methods, and therefore solar power systems, which were previously used for lighting, ventilation, and other purposes in buildings, have been realized.

[0004] In other words, the solar power system is a building envelope technology that generates electricity while serving as a building material by installing PV modules (Photovoltaic Modules) on buildings. This is used as an exterior material for buildings in addition to producing electricity from solar energy and supplying it to consumers.

[0005] Meanwhile, the conventional solar system described above has also been adapted to the wall of a building so that images can be displayed.

[0006] However, when applying a display device capable of displaying images to such a solar system, in the past, a display device that transmits solar energy was placed in front to prevent a decrease in the efficiency of collecting solar energy, and a PV module was placed behind the display device, which caused a problem of the PV module not properly collecting solar heat.

[0007] Furthermore, a structure in which a PV module is disposed in the front and a display device is disposed on the rear side of the PV module does not allow for any exterior wall configuration of a building. Summary of the Invention [Problem to be solved by the invention]

[0008] The technical objective of the present invention is to provide a solar system capable of front image display, which is capable of displaying various types of images outside through the secured electric energy while increasing the amount of power generation by efficiently collecting solar energy through the PV module by configuring the PV module to be able to display an image on the front side when the PV module is installed in a building, thereby securing electric energy through efficient collection of solar energy through the PV module. [Means for solving the problem]

[0015] The pattern portion is an embossed protrusion.

[0016] Also, the pattern portion is a protruding structure bent into any one of a "V" shape, a "", a "U" shape, and a "V" shape.

[0017] The LED module also includes a lamp fixing part fixed to the other side of the back cover and having a box-shaped structure opened toward the PV module; a substrate accommodated in the lamp fixing part; at least one LED element mounted on the substrate; and a transparent cover window coupled to the opening of the lamp fixing part for guiding the light source of the LED element to be emitted to the outside through the back cover, the light source emission port, and the front cover when the LED element is turned on or blinking.

[0018] In addition, the lamp fixing portion is adhesively fixed to the other surface of the back cover by a transparent adhesive layer formed on the transparent cover window.

[0019] The transparent adhesive layer is a silicone adhesive or an adhesive sheet.

[0020] The transparent adhesive layer is formed on the transparent cover window by a lamination method or a hot pressing method.

[0021] In addition, the module driving unit is at least one or more board structures that can be attached and detached via fastening members on the side of the module frame, and is molded for waterproofing and moisture resistance, and a driving circuit including a DC-DC converter is mounted on the board structure.

[0022] The controller is also communicatively coupled to the module driver.

[0032] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0033] FIG. 1 is a schematic block diagram of a solar system capable of front image display in an embodiment of the present invention, FIG. 2 is an oblique view showing the structure of a solar system capable of front image display in an embodiment of the present invention, FIG. 3 is an exploded view showing the structure of a solar system capable of front image display in an embodiment of the present invention, FIG. 4 is a front view showing the structure of a solar system capable of front image display in an embodiment of the present invention, and FIG. 5 is a schematic cross-sectional view showing the state in which an LED module is adhesively fixed to a PV module in an embodiment of the present invention.

[0034] Referring to the attached Figs. 1 to 5, a solar system capable of displaying a front image according to an embodiment of the present invention can be installed in a building, and includes a module frame 10, a PV module 20, an LED module 30, a module driver 40, a controller 50, and / or a battery 60 and an inverter 70.

[0035] The module frame 10 is a rectangular frame structure that is installed on an exterior wall or an opening in an exterior wall to isolate the inside of a building from the outside.

[0036] On both sides of the module frame 10, there may be formed a coupling groove (not shown) into which the PV module 20 is fitted, and a junction box JB electrically connected to the PV module 20 and an outlet path (not shown) in which the inverter 70 and cable C1 connected thereto are disposed.

[0037] The PV module 20 is a rectangular panel structure whose both ends are fitted into the module frame 10 having a square frame shape to collect solar energy and generate electricity. The PV module 20 includes a front cover 21, a back cover 22, and solar cells 23.

[0038] The front cover 21 is a plate-like structure made of transparent glass or synthetic resin material, and is fixed to the front side of the module frame 10.

[0039] The back cover 22 is a plate-shaped structure made of transparent glass or synthetic resin, and is fixed to the rear side of the module frame 10 while maintaining a certain gap with the front cover 21.

[0040] The solar cell 23 is arranged in multiple rows while maintaining a predetermined interval so that a light source emission port 23a is formed in the gap maintained between the front cover 21 and the back cover 22, and is electrically connected to the junction box JB and / or the inverter 70 via a cable C1.

[0041] Here, the solar cell 23 may be a single-sided or double-sided battery cell, and the cable C1 connected to the junction box JB and / or inverter 70 electrically connected to the solar cell 23 may be connected via a cable jack J1.

[0042] Although not shown in the drawing, protective sheets may be laminated on both sides of the solar cell 23, and the protective sheets may contain fine particles whose main component is ethylene vinyl acetate (hereinafter referred to as "EVA") resin.

[0043] Although the front cover 21 and the back cover 22 are described as being made of a transparent material, they may be made of a semi-transparent or polymer material (eg, ETFE, etc.) The front cover 21 transfers solar energy to the solar cell 23.

[0044] Although not shown in the drawings, a pattern portion for expanding a reflection area and a heat dissipation area may be formed on one side of the back cover 22. The pattern portion may be an embossed protrusion or a protruding structure bent into any one of a "V" shape, a "" shape, a "U" shape, or a "V" shape.

[0045] When solar energy is collected by the solar cells 23 in the PV module 20, the back cover 22 can reflect some of the solar energy that passes through without being collected to the solar cells 23. Therefore, it is possible to increase the amount of electricity produced while improving the heat collection performance of the solar cells 23. Therefore, it is preferable that the solar cells 23 are formed in a double-sided cell structure rather than a single-sided cell structure.

[0046] The LED module 30 is arranged in multiple stages on the back cover 22 included in the PV module 20, and emits light so as to display an image in the forward direction of the PV module 20 using electricity produced by the PV module 20 as a driving power source. The LED module 30 includes a lamp fixing part 31, a substrate 32, an LED element 33, and a transparent cover window 34.

[0047] The lamp fixing part 31 is fixed to the other surface of the back cover 22 by a transparent adhesive layer 25 and has a box-shaped structure that is open toward the PV module 20 .

[0048] The substrate 32 is made of a flexible material and is accommodated in and fixed to the lamp fixing portion 31 .

[0049] The LED element 33 is at least one chip LED mounted on the substrate 32 and is protected by the transparent cover window 34 .

[0050] The transparent cover window 34 is coupled to the opening of the lamp fixing part 31 and guides the light source of the LED element 33 when it is turned on or blinking to be emitted to the outside through the back cover 22, the light source emission port 23a, and the front cover 21.

[0051] The transparent adhesive layer 35 described above is formed on the transparent cover window 34 , and serves to adhesively fix the lamp fixing portion 31 to the other surface of the back cover 22 .

[0052] The transparent adhesive layer 35 is a silicone adhesive or an adhesive sheet, which can be formed on the transparent cover window 34 by a lamination method or a hot pressing method.

[0053] The transparent adhesive layer 35 is made of EVA (Ethylene Vinyl Acetate) resin and may be formed on the transparent cover window 34 formed at the opening of the lamp fixing part 31 by a hot press method or a lamination method.

[0054] The module driver 40 drives the LED module 30 to turn on, turn off or blink. Therefore, it is at least one or more board structures that can be attached and detached via fastening members to the side of the module frame 10, and may be molded for waterproofing and moisture-proofing. Although not shown in the drawings, a driving circuit including a DC-DC converter may be mounted on the board structure.

[0055] The controller 50 outputs signals to the module driver 40 for controlling the supply or non-supply of electricity produced by the PV module 20 and the driving pattern of the LED module 30, such as turning on, turning off, or blinking, and the controller 50 is communicatively connected to the module driver 40 via a wired or wireless communication network.

[0056] The battery 60 is mounted on the module frame 10 and can supply driving power to the LED module 30 and the module driver 40 while being charged by electricity generated from the PV module 20 .

[0057] The solar system capable of displaying a front image according to an embodiment of the present invention is configured by installing a single solar system P1 as shown in FIG. 6 attached to a building or by installing at least one or more solar systems P1, ..., P6 in series using one main frame as shown in FIG. 7, as shown in attached FIG. 1 to FIG. 7.

[0058] The rectangular PV modules 20 arranged in multiple stages in the solar power system P1 or P1, ..., P6 collect solar energy and generate electricity. The generated electricity can be used as a driving power for the LED module 30 and the module driver 40.

[0059] A controller 50, which is communicatively connected to the module driver 40 via a wired or wireless communication network, transmits a signal for controlling a driving pattern of turning on, off or blinking of the multi-stage LED modules 30 to the module driver 40. Then, the module driver 40 drives the LED modules 30 according to the control signal. Therefore, in a single solar system P1 or at least one or more solar systems P1, ..., P6, an image can be displayed according to a driving pattern of turning on, off or blinking of the LED elements 33.

[0060] In other words, the light source generated by the lighting or blinking of the LED element 33 passes through the back cover 22 included in the PV module 20, and then passes through the light source emission opening 23a formed between the solar cell cells 23, and then passes through the front cover 21 again.

[0061] The light source of the LED elements 33, which emit light by turning on, off or blinking according to the drive pattern control signal of the controller 50, does not affect the heat collection of the solar energy of the solar battery cells 23. Accordingly, a predetermined still image or moving image can be displayed from the front side of the PV module 20 so that people outside can watch it.

[0062] Although the technical concept of the solar system capable of displaying a front image of the present invention has been described above with reference to the accompanying drawings, this is merely an illustrative description of the best embodiment of the present invention and is not intended to limit the present invention.

[0063] Therefore, the present invention is not limited to the specific preferred embodiments described above, and it goes without saying that various modifications can be made by anyone having ordinary skill in the art to which the invention pertains without departing from the gist of the present invention as claimed in the claims, and such modifications are intended to fall within the scope of the claims.
