Description

Solar power generation light-emitting panel with light reflection layer
Technical Field
The present invention relates to a solar power generation light-emitting panel, and more particularly, to a solar power generation light-emitting panel having a light reflection layer, which can emit light or display light while generating solar power, thereby improving space utilization.
Background
Renewable energy does not emit hazardous substances such as pollutants, warming, and radioactive energy, and is considered as clean energy that does not require reprocessing facilities and the like. These renewable energy sources exist in various forms such as wind power, wave power, solar energy, and geothermal energy, but solar energy is most commonly used because of its greatest diversity in scale, convenience in installation and operation.
Recently, systems such as certified Emissions Reduction (certified Emissions Reduction) have been implemented worldwide in order to reduce greenhouse gas Emissions, making renewable energy sources more important. Therefore, various methods for increasing power generation by renewable energy are being actively attempted. In particular, these attempts have focused on solar energy, which is more convenient than other power generation approaches.
However, solar energy is also subject to space limitations despite its greater convenience. Therefore, there is a constant attempt to use solar power panels in combination with other devices, but no epoch-making solution has been proposed.
In particular, recently, due to the trend of pursuing aesthetic elements, restrictions on the installation environment are also increased. However, since most solar power generation panels are made of polycrystalline silicon, it is difficult to satisfy additional requirements of aesthetic elements.

It should be noted that, in assigning reference numerals to the structural elements of the respective drawings, the same reference numerals are assigned to the same structural elements as much as possible even though they are shown in different drawings. Also, in describing the present invention, when it is judged that a detailed description of related well-known functions or well-known structures obstructs understanding of the gist of the present invention, a detailed description thereof will be omitted. Moreover, some features illustrated in the drawings have been enlarged or reduced or simplified for ease of description, and the drawings and their structural elements are not necessarily shown to scale. However, those skilled in the art will readily understand these details.
Fig. 1 is a schematic structural view showing the structure of a solar power generation light-emitting panel provided with a light reflection layer according to the present invention.
Referring to fig. 1, a solar power generation light-emitting panel 1 having a light reflection layer according to the present invention includes a substrate 10, a display panel 20, a solar cell 30, a light filtration layer 40, and a cover sheet 50.
The substrate 10 serves as a base frame for forming the display panel 20, the solar cell 30, and the light filtering layer 40. A light emitting section 20, a solar cell 30, and a light filter layer 40 are sequentially formed on one surface of the substrate 10.
In particular, the substrate 10 of the present invention is formed of a synthetic resin or a thin film metal in order to maintain the flexibility of the panel 1. As an example, synthetic resins such as Polyimide (Polyimide), Polycarbonate (Polycarbonate), Polyethylene terephthalate (Polyethylene terephthalate), and Polyethylene (Polyethylene) may be used. Also, in the case of using a metal, a metal or an alloy such as stainless steel, an aluminum alloy, a copper alloy may be processed to form a thin film. In particular, in the case of using metal, the temperature of the panel 1 can be lowered by releasing or conducting the heat transferred from the display panel 1A or the battery panel 1B.
The substrate 10 may be made of non-flexible synthetic resin, glass, and metal, and is not limited to the illustrated structure.
The display panel 20 functions as a lighting or a display unit for displaying video at a place where the panel 1 is provided by providing a light emitting device or a light emitting surface at the display panel 20. For this reason, the display panel 20 has a light emitting diode device or an organic light emitting diode device (hereinafter, description is made assuming that the light emitting device is a light emitting diode). These display panels 20 include printed circuit boards 23 and light emitting diodes 21.
Specifically, the printed circuit board 23 has a circuit for driving the light emitting diodes 21. On the printed circuit board 23, a scanning line and a data line as conductive lines for supplying selection and data (or light emission signals) of the light emitting diodes 21 are formed, and a plurality of light emitting diodes 21 are mounted. In particular, the printed circuit board 23 may be formed of a flexible substrate.
The printed circuit board 23 incorporates a plurality of light emitting diodes 21, and the light emitting diodes 21 are arranged as a multicolor light source that emits a specific color under the control of a control unit (not shown). The light emitting diodes 21 are arranged in a predetermined pattern and at predetermined intervals. These light emitting diodes 21 may function as illumination for illuminating the installation space by emitting light of a specific color, and may be formed of pixels (pixels) to display an image or video. The above-described Light Emitting Diode 21 may be implemented using a Light Emitting Diode 21 device produced in a single device unit, and may also be implemented using a display device such as an Organic Light Emitting Diode (Organic Light Emitting Diode). As shown in fig. 1, light emitting devices such as the above-described light emitting diodes 21 are arranged on a printed circuit board 23 at predetermined intervals and in an array.
The display panel 20 may receive power generated from the solar cell 30 to perform a light emitting operation. For this purpose, the display panel 20 and the solar cell 30 may be connected via a power supply unit (not shown), and a battery (not shown) for storing electric power generated by the solar panel 1B may be disposed in the power supply unit (not shown). A control unit for controlling display on the display panel 20 may be provided in the power supply unit (not shown). The above will be described in more detail below with reference to other figures. In which the power generated by the solar cell 30 is supplied to the external device through the power system or the power supply device, and the power for driving the display panel 20 may be received through a power source other than the solar cell 30, and the present invention is not limited to what has been described.
The solar cell 30 is disposed around the light emitting device, i.e., the light emitting diode 21, of the display panel 20. Specifically, the solar cell 30 is attached to the printed circuit board 23 of the display panel 20. For this, the solar cell 30 forms a window 31 at a position corresponding to the light emitting diode 21. The above-described window 31 may be understood as a hole formed on the solar cell 30. The above-described solar cell 30 is configured by using a metal thin film solar cell such as copper indium gallium selenide (GIGS) to secure flexibility of the panel 1, and may be formed by perforating a thin film. In addition, the above-described solar cell 30 may be configured by using, for example, cadmium telluride (CdTe) and Dye Sensitized Solar Cell (DSSC).
The light filtering layer 40 transmits or reflects light of a specific wavelength band and is disposed at an upper portion of the solar cell 30, i.e., an incident direction of the light, to cover the light emitting diode 21 exposed through the solar cell 30 and the window 31. The light filter layer 40 may be formed of a plurality of layers, and may use selective reflection characteristics of cholesteric liquid crystal, but the present invention is not limited to a specific form or any type of filter. That is, the light filtering layer 40 of the present invention can transmit sunlight of a wavelength band in which solar power generation can occur, wherein any filter may be used as long as it can be configured as a filter capable of reflecting light of a specific band. In particular, among these filters, it is preferable to use a filter which can have flexibility and can form a membrane property.
These light filter layers 40 reflect light of a predetermined band of light incident through the front surface, i.e., the incident direction of light, and transmit the remaining light to the solar cell 30. Further, the light generated from the light emitting diode 21 on the rear surface can be transmitted to the front surface and released. Thereby, the light filter layer 40 can display a specific color different from the existing one by the light reflected by the panel 1. In particular, the light filtering layer 40 of the present invention reflects only a portion of light and transmits the rest of light to minimize a reduction in power generation efficiency.
The panel structure and features of the present invention are described in more detail below with reference to other figures.
Fig. 2 is a schematic sectional view schematically showing a section of the panel of fig. 1.
Referring to fig. 2, the panel of fig. 1 as described above is formed by stacking the panels in the same manner as in fig. 2.
A printed circuit board 23 is provided on the upper surface of the substrate 10, i.e., the incident direction of light, and a first adhesive layer for adhering the printed circuit board 23 to the substrate 10 is provided.
The first adhesive layer 11a may be composed of a material such as Polyolefin (polyofin), Polyolefin elastomer (polyofin elastomer), ethylene-Vinyl acetate copolymer (EVA), polyvinyl Butyral (PVB). Among them, the first adhesive layer 11a may include a heat conductive substance in the adhesive substance to increase the heat conductivity, or may be replaced with a heat conductive substance.
The solar cell 30 is attached to the upper portion of the printed circuit board 23, and a window 31 is formed at a position corresponding to the light emitting diode 21, and the solar cell 30 is disposed in a space formed between the light emitting diode 21 and the window. A second adhesive layer 11b for bonding the printed circuit board 23 and the solar cell 30 is provided. The second adhesive layer 11b may be made of, for example, the same polyolefin, polyolefin elastomer, ethylene-vinyl acetate copolymer, or polyvinyl butyral as the first adhesive layer 11 a.
A light filtering layer 40 may be disposed on the upper portion of the solar cell 30. The light filter layer 40 may be attached to the upper portion of the solar cell 30 by the third adhesive layer 11c after being processed and produced in a thin film form. The third adhesive layer 11c is formed of a transparent adhesive of the first adhesive layer 11a and the second adhesive layer 11 b. In particular, the third adhesive layer 11c functions as a planarization layer. That is, the upper surface of the solar cell 30 becomes uneven due to the difference in thickness between the solar cell 30 and the light emitting diode 21 and the margin caused by the window 31, and thus, plays a role of eliminating and planarizing the unevenness. Thereby, the light filtering layer 40 can be attached to the planarized surface.
Also, the panel 1 of the present invention may further include a cover plate 50. The cover sheet 50 may be processed in a thin film form and attached to the light filtering layer 40, in which case the fourth adhesive layer 11d may be formed between the light filtering layer 40 and the cover sheet 50.
The cover sheet 50 may be formed of polymethyl methacrylate (PMMA), Polycarbonate (PC), reinforced plastic, or an equivalent thereof, and may be formed of various materials depending on whether the display panel 1A is formed as a flexible panel. Also, a silicon oxide layer formed of a diamond nano-powder layer or an atmospheric pressure plasma coating may be formed on the first cover sheet 50a to enhance strength.
Fig. 3 is a schematic diagram showing an example including a control unit for a control panel.
Referring to fig. 3, the panel 1 of the present invention may further include a control portion 60, a power supply portion 70, and a sensor portion 80.
The control unit 60 controls lighting and brightness of the light emitting diodes disposed on the panel 1. The specific control method of the control unit 60 differs depending on whether the light emitting diodes 21 arranged on the panel 1, that is, the light emitting devices perform a simple lighting function or display a video.
Such a control section 60 controls the illuminance of a part or the whole of the light emitting diode 21 based on a value detected from the sensor section 80 or a time value measured by a timer.
Specifically, the panel 1 of the present invention has a light filter layer 40, and the light filter layer 40 has a property of reflecting a part of light. Therefore, the control section 60 can perform illuminance control of the light emitting diode 21 to reduce the amount of light of the light emitting diode 21 having the same wavelength as the light reflected by the light filter layer 40. In particular, since the reflection of light is formed in the daytime, the control unit 60 controls light having the same wavelength as the reflected light to be output less than other light in the case of daytime, for example, where the amount of light incident on the panel 1 is large, and controls the control unit 60 to output the same amount of light in the case of nighttime or cloudy day when the amount of incident light is small. For this, the sensor portion 80 is provided to measure the amount or illuminance of light incident on the panel 1 to adjust the illuminance of the light emitting diode 21.
In particular, as shown in fig. 3, the above-described light filtering layer 40 may be configured to reflect light of different wavelengths or reflect only a part of the region B according to the region of the power generation surface.
In this case, when the light emitting diode 21 located in the B region emits light in the same manner as the other regions without illuminance control, the B region has an effect that a specific color appears brighter due to the reflected light and the light emitted by the light emitting diode 21.
For example, when a light filter layer is provided so that the B region reflects blue and the light emitting diode 21 is lit at full white, the color of the photo-print emitted from the light emitting diode 21 becomes white in the other region a, and the panel color of the a region appears as the color of the solar cell 30.
In this case, in the B region, the surface of the solar cell 30 shows green due to reflection by the light filtering layer 40. In the region B, the reflected light and the emission light of the light-emitting diode 21 are mixed, so that the green light becomes stronger, and an effect of causing the light-emitting diode to output blue with higher luminance also occurs.
Therefore, in order to make the light emitting diodes 21 in the a region and the B region output the same color, it is necessary to control the luminance of the light reflected by the light emitting diodes 21 in the B region or the a region in consideration. That is, in the above example, the blue output of the B-region light emitting diode 21 should be decreased, or the blue output of the a-region light emitting diode 21 should be increased.
For this reason, the control section 60 measures the illuminance of light incident on the panel 1 through the sensor section 80, and performs luminance control of the light emitting diodes accordingly. In more detail, the illuminance of sunlight corresponding to the wavelength of light reflected by the light filter layer 40 is measured, and the luminance control is performed on the same wavelength of the light emitting diode 21. In particular, during the period of supplying sunlight to the panel 1, the luminance reduction control is performed on the light emitting diodes 21 of the target wavelength, so that the light emitting diodes 21 of the target wavelength emit light of the same luminance as the other light emitting diodes 21 at night or at the time of sunlight reduction.
In these controls, it is possible to realize by using a timer without using the sensor portion 80. That is, the time is specified according to sunrise and sunset, and the luminance control can be performed according to the time.
The power supply section 70 supplies power for lighting the light emitting diodes 21 to the panel 1. In this case, the power supplied from the power supply unit 70 may be supplied to the panel 1 through the control unit 60, but the present invention is not limited thereto. These power supply units 70 may be connected to an external power supply unit to supply power supplied from the power supply units to the panel 1, or may supply power generated by the solar cells 30 to the panel 1. For this, the power supply part 70 may include a secondary battery, and may include a charging part for charging the secondary battery with the electric power generated by the solar cell 30.
Fig. 4 is a schematic view showing an example of the panel 1 of another embodiment of the present invention.
Referring to fig. 4, the panel 1 according to another embodiment of the present invention further includes a second display panel 120 disposed on the other side of the substrate 10. Hereinafter, only the differences from the above-described embodiments are mainly described, and detailed description of the same structures is omitted.
In the above-described embodiment, the example in which the display panel 20 and the power generation panel 30 are arranged together on one side of the substrate 10 of the panel 1 has been described.
In this embodiment, the same structure as in the above-described embodiment is disposed on one surface of the substrate 10, and the second display panel 20 is disposed on the other surface.
To this end, the other side of the substrate is attached to a second printed circuit board 23b by a fifth adhesive layer 11 e.
In this case, the second printed circuit board 23b configures a plurality of second light emitting diodes 21 b.
The sixth adhesive layer 11f covers the second printed circuit board 23b and the second light emitting diode 21b, and the second cover sheet 50b is attached to the second printed circuit board by the sixth adhesive layer 11 f.
Although the technical idea of the present invention has been shown and described in the above with the specific embodiments, the present invention is not limited to the same configuration and action as the specific embodiments described above, as long as various modifications can be made without departing from the scope of the present invention. Accordingly, such variations are to be regarded as being within the scope of the invention, which is to be determined from the claims.
