  The present invention relates to a sign panel such as an advertising board, a guidance display version, and a signboard, and more particularly to a solar integrated display panel system, a solar integrated display panel, and a manufacturing method thereof.

  Patent Document 1 has a surface light emitter that emits surface light with uniform luminance in both directions of the front surface side and the back surface side, and a printed film on which an arbitrary pattern is printed is sandwiched between the solar cell and the surface light emitter.

  However, since the surface light emitter of Patent Document 1 emits surface light with uniform brightness in both the front side and the back side, it emits more light than necessary for symbol display, and the amount of emitted light is wasted regardless of the symbol. There is a problem that.

  Patent Document 2 is a reflection type that irradiates a signboard with an LED light, and a part of the emitted light amount is off or transmitted through the signboard. Therefore, the light emission amount of the LED with respect to the brightness or luminance of the signboard itself. Only a part contributes. Thus, there is a problem that waste occurs in the amount of light emitted from the LED. Alternatively, in order to ensure a certain level of brightness or brightness on the signboard, it is necessary to supply power corresponding to a wasteful light quantity due to reflection, and there is a problem that power consumption for the brightness or brightness of the signboard is large.

  In patent document 3, it is a reflection type which irradiates an acrylic board from LED with which the end of the acrylic board which is a main body of a signboard is provided, The problem similar to patent document 2, ie, wasteful generation | occurrence | production or consumption of emitted light There is a problem that electric power is large.

  An object of the present invention is to provide a solar-integrated display panel system that improves the brightness of the panel and reduces power consumption, and a method for manufacturing the same.

  In order to solve the above problems, a solar integrated display panel system of the present invention has a plurality of light emitting diodes surface-mounted along a pattern and a transparent electrode pattern for electrically connecting the plurality of light emitting diodes on the surface. A transparent light-emitting panel, a solar panel that is superimposed on the back surface of the transparent light-emitting panel and converts incident light that passes through the transparent light-emitting panel into electrical energy, a chargeable / dischargeable storage battery, and a connection between the solar panel and the storage battery And a controller that switches connection between the storage battery and the transparent light-emitting panel.

  According to this configuration, the brightness (brightness) of the panel can be improved and the power consumption can be reduced.

  Specifically, first, since each light-emitting diode is surface-mounted, the display direction of the transparent light-emitting panel and the light-emitting direction of each light-emitting diode substantially coincide, and light is emitted to the eyes of the person viewing the transparent light-emitting panel. The light from the diode reaches the eyes directly, not indirectly. That is, almost all of the light emission amount of the LED contributes to the brightness or luminance of the panel itself. Thereby, compared with conventional indirect illumination such as an irradiation type, waste of the amount of emitted light can be greatly reduced, and high luminance can be secured with less power consumption.

  Secondly, since a plurality of light emitting diodes are surface-mounted along the design, only the portion of the design emits light, not the entire surface, as compared with the conventional surface light emitter, greatly reducing the amount of wasted light emission. be able to.

  Here, the solar panel may further have a design corresponding to a design formed on a surface of the solar panel and the design of the plurality of light emitting diodes.

  According to this configuration, the pattern formed on the solar panel itself is displayed in a period in which the transparent light emitting panel does not emit light (a period in which the storage battery is charged), while in the period in which the transparent light emitting panel emits light, a plurality of The pattern by the light emission of the light emitting diode can be displayed. Thereby, the same design can be displayed day and night, and the appeal power as sign panels, such as an advertisement, a signboard, and a guide board, can be improved regardless of day and night. Moreover, since the power charged in the daytime can be used at night, the maintenance cost can be reduced.

  Here, the solar panel has a protective film formed on a surface thereof, and the protective film has a non-uniform film thickness to form the design, and the protective film in a portion corresponding to the design The film thickness of is different from the film thickness of the protective film in the part not corresponding to the symbol, and the protective film in the part corresponding to the symbol may reflect light corresponding to the color of the symbol.

  According to this configuration, the shape and color of the symbol can be formed by the protective film having a film thickness corresponding to the color of the symbol. That is, the pattern can be formed in an arbitrary shape as a part of the protective film by the manufacturing process of the solar panel, so that the design can be made extremely fine. And since the color reflected by the protective film corresponding to a pattern is dependent on the film thickness, a colorful pattern is realizable with the manufacturing process of a solar panel panel. In addition, since the protective film corresponding to the design transmits light other than the reflected color, the design portion does not completely block the incident light. Thereby, the fall of the power generation efficiency of the solar panel by a design can be suppressed to the minimum.

  Here, the design includes a first design portion representing a first color and a second design portion representing a second color different from the first color, and the first design portion includes the protection portion. The film is formed by a portion having a first film thickness corresponding to the first color, and the second pattern portion is a second film corresponding to the second color in the protective film. You may make it form by the part which has thickness.

  According to this configuration, by receiving a plurality of portions having different thicknesses in the protective film, it is possible to accurately realize a color design on the surface of the solar panel.

  Further, the solar integrated display panel of the present invention is a transparent light-emitting panel having a plurality of light-emitting diodes surface-mounted along a pattern and a transparent electrode pattern electrically connecting the plurality of light-emitting diodes on the surface, A solar panel that is superimposed on the back surface of the transparent light-emitting panel and converts incident light transmitted through the transparent light-emitting panel into electrical energy.

  According to this configuration, the brightness (brightness) of the panel can be improved and the power consumption can be reduced.

  Specifically, first, since each light-emitting diode is surface-mounted, the display direction of the transparent light-emitting panel and the light-emitting direction of each light-emitting diode substantially coincide, and light is emitted to the eyes of the person viewing the transparent light-emitting panel. The light from the diode reaches the eyes directly, not indirectly. That is, almost all of the light emission amount of the LED contributes to the brightness or luminance of the panel itself. Thereby, compared with conventional indirect illumination such as an irradiation type, waste of the amount of emitted light can be greatly reduced, and high luminance can be secured with less power consumption.

  Secondly, since a plurality of light emitting diodes are surface-mounted along the design, only the portion of the design emits light, not the entire surface, as compared with the conventional surface light emitter, greatly reducing the amount of wasted light emission. be able to.

  The solar integrated display panel system manufacturing method of the present invention includes a plurality of surface mounted light emitting diodes, and a transparent light emitting panel having a transparent electrode pattern on the surface for electrically connecting the plurality of light emitting diodes, A method of manufacturing a solar-integrated display panel system having a solar panel that is superimposed on the back surface of the transparent light-emitting panel and converts incident light that passes through the transparent light-emitting panel into electrical energy, and creates line drawing data indicating a pattern Determining a light-emitting diode arrangement position on the transparent light-emitting panel and a transparent electrode pattern arrangement position for connecting the light-emitting diodes along a pattern indicated by the line-drawing data; and A protective film pattern having a film thickness corresponding to the color of the pattern is applied to the solar pattern. And a step of forming on Le.

  A solar integrated display panel system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a solar integrated display panel system according to an embodiment of the present invention. As shown in the figure, the solar integrated display panel system 1 includes a solar integrated display panel (hereinafter referred to as a panel unit) 10, a control unit 300, and a storage battery 400. The panel unit 10 includes a solar panel 100, a transparent light emitting panel 200, a protective panel 600, a lower housing 510, and an upper housing 520. In FIG. 1, the panel unit 10 is an exploded view. FIG. 2 shows a cross-sectional view of the panel portion 10 after assembly.

  The solar integrated display panel system according to the embodiment of the present invention includes at least a transparent light emitting panel 200, a solar panel 100, a storage battery 400, and a control unit 300, as in the configuration example shown in FIGS.

  The transparent light emitting panel 200 has a plurality of light emitting diodes 230 surface-mounted along a design and a transparent electrode pattern 220 that electrically connects the plurality of light emitting diodes 230 on the surface. Here, the symbols include, for example, all symbols such as characters, figures, patterns, pictures, illustrations, photographs, etc., and may be color or monochrome. In FIG. 1, the character string “KOREA” is shown as an example of a symbol.

  The solar panel 100 is superimposed on the back surface of the transparent light emitting panel 200 and converts incident light transmitted through the transparent light emitting panel 200 into electric energy. The solar panel 100 of FIG. 1 shows a configuration example including a plurality of solar modules 110 combined in a planar shape, but may be configured of a single solar module 110.

  The storage battery 400 is a chargeable / dischargeable storage battery 400.

  The controller 300 switches the connection between the solar panel 100 and the storage battery 400 and the connection between the storage battery 400 and the transparent light emitting panel (200). For example, the control unit 300 connects the solar panel 100 and the storage battery 400 during the daytime, and connects the storage battery 400 and the transparent light emitting panel (200) at nighttime. Thereby, the electric energy from the solar panel 100 is charged to the storage battery 400 during the daytime, and the transparent light emission panel 200 is caused to emit light by supplying power from the storage battery 400 to the transparent light emission panel 200 at night.

  By configuring the solar integrated display panel system 1 in this way, there are effects of improving the brightness and brightness of the panel unit 10 and improving the power consumption efficiency.

  More specifically, first, since each light-emitting diode is surface-mounted, the display direction of the transparent light-emitting panel and the light-emitting direction of each light-emitting diode substantially coincide with each other. Light from the light emitting diodes reaches the eyes directly, not indirectly. That is, almost all of the light emission amount of the LED contributes to the brightness or luminance of the panel itself. Thereby, compared with conventional indirect illumination such as an irradiation type, waste of the amount of emitted light can be greatly reduced, and high luminance can be secured with less power consumption.

  Secondly, since a plurality of light emitting diodes are surface-mounted along the design, only the portion of the design emits light, not the entire surface, as compared with the conventional surface light emitter, greatly reducing the amount of wasted light emission. be able to.

  Furthermore, if the solar panel 100 is configured as follows, the same design can be displayed day and night, and the appeal of advertisements, signboards, information boards, etc. can be improved regardless of day or night. The effect that can be produced.

  The solar panel 100 has a pattern (a character string “KOREA” in the example of FIG. 1) formed on the surface thereof, and the plurality of light emitting diodes 230 on the surface of the transparent light emitting panel 200 and the transparent electrode pattern 220 are formed of the solar panel. It is good also as a structure arrange | positioned along 100 symbols.

  In this case, the above design can be formed by setting the thickness of the protective film 120 as shown in FIG. The solar panel 100 has a protective film 120 formed on the surface thereof. The film thickness of the portion corresponding to the design (for example, the protective film 120a) of the protective film 120 is different from the thickness of the portion not corresponding to the design (protective film 120), and reflects the light corresponding to the color of the design. It is formed to do.

  Next, the transparent light emitting panel 200 will be described with reference to FIGS.

  As shown in FIG. 2, in the panel unit 10, the back surface of the transparent light emitting panel 200 (the surface having no light emitting diode) is disposed on the light receiving surface of the solar panel 100. The solar panel 100 and the transparent light emitting panel 200 are overlaid together.

  On the surface of the transparent light emitting panel 200 (opposite side of the solar panel 100), the transparent electrode pattern 220 and the LED 230 are arranged along the design.

  Further, a protective panel 600 is overlaid on the transparent light emitting panel 200. The protection panel 600 is made of glass or resin.

  The lower housing 510 and the upper housing 520 integrally support the solar panel 100, the transparent light emitting panel 200, and the protection panel 600. The solar panel 100 and the transparent light emitting panel 200 may be bonded together with a transparent adhesive. Similarly, the protective panel 600 and the transparent light emitting panel 200 may be bonded together with a transparent adhesive. The lower housing 510, the solar panel 100, and the upper housing 520 may be bonded with an adhesive.

  FIG. 3 is a diagram illustrating a configuration of symbols on the transparent light emitting panel 200. This figure shows a part “K” of the symbol on the transparent light emitting panel 200 and an enlarged view of the part. In this example, the symbol on the transparent light emitting panel 200 corresponds to the symbol on the surface of the solar panel 100. The design on the transparent light emitting panel 200 is drawn by the arrangement pattern of the plurality of light emitting diodes 230. In the example of the enlarged view in the broken line in FIG. 3, a plurality of LEDs 230 are connected in series via the transparent electrode pattern 220 to constitute a part of the design.

  FIG. 4 is a diagram illustrating another example of the arrangement pattern of the light emitting diodes 230. Instead of the arrangement shown in the enlarged view of FIG. 3, light emitting diodes may be arranged in combination of parallel connection and series connection as shown in FIG.

  FIG. 5 is a cross-sectional view of the transparent light emitting panel 200. As shown in the figure, the transparent light emitting panel 200 includes a transparent panel 210, a transparent electrode pattern 220 formed on the surface of the transparent panel 210, and an LED 230 electrically connected by the transparent electrode pattern 220.

  The transparent panel 210 is typically a glass substrate, but may be a resin substrate or a transparent sheet.

  The transparent electrode pattern 220 is a thin film formed of, for example, ITO (Indium Tin Oxide).

  The LED 230 has two terminals 231 (an anode and a cathode) soldered to the transparent electrode pattern 220 and is surface-mounted on the transparent panel 210. The main light emitting direction of the LED 230 is a vertical direction from the surface of the transparent light emitting panel 200.

  Furthermore, the solar panel 100 is demonstrated using FIGS.

  FIG. 6 is a diagram illustrating an example of a pattern formed on the solar panel. In the same figure, the same character string design as FIG. 1 is illustrated. Here, an example in which each character of “KOREA” is configured to indicate a different color will be described. 7 to 11 are cross-sectional views showing the AA cross section, ..., EE cross section of FIG.

  The solar panel 100 has a protective film 120 formed on the surface thereof. This protective film 120 is a transparent thin film of silicon oxide, for example.

  The film thicknesses (ta to te) of the portions of the protective film 120a to 120e corresponding to the pattern in the entire surface of the protective film are different from the film thickness of the portion of the protective film 120 not corresponding to the pattern. The thicknesses of the protective films 120a to 120e corresponding to the symbols are set so as to reflect light corresponding to the colors of the symbols. Each film thickness (ta to te) can be determined by setting an integral multiple of a half wavelength (λ / 2) of light of a desired color for reflection.

  Thus, the shape and color of the symbol can be formed by a protective film having a film thickness corresponding to the color of the symbol. Since the pattern can be formed in any shape as a part of the protective film by the manufacturing process of the solar panel, it can be formed with extremely high definition. Since the color reflected by the protective film corresponding to the design depends on the film thickness, a colorful design can be realized by the manufacturing process of the solar panel panel.

  Of the entire surface of the protective film, the portion of the protective film 120 that does not correspond to the pattern is formed as an antireflection film that not only protects but also prevents reflection of incident light as much as possible.

  For example, when attention is paid to “K” and “O” among the symbols, the symbol has a first symbol portion “k” (protective film 120a) representing the first color and a second color different from the first color. 2nd design part "O" (protective film 120b) to represent. The first symbol portion “K” is formed by a portion of the protective film having a first film thickness ta corresponding to the first color in the protective film. The second symbol portion “O” is formed by the portion of the protective film 120b having the second film thickness tb corresponding to the second color in the protective film.

  FIG. 12 is a block diagram showing the configuration of the solar integrated display panel system. In the figure, the configuration of the control unit 300 of FIG. 1 is shown in more detail. The control unit 300 includes a switch 310, a switching control unit 311, and an LED control unit 320.

  The switch 310 is a switch that switches connection between the solar panel 100 and the storage battery 400 and connection between the storage battery 400 and the transparent light emitting panel 200.

  The switching control unit 311 controls switching of the switch 310. For example, the switching control unit 311 has a clock inside, controls the switch 310 so as to connect the solar panel 100 and the storage battery 400 in the first time zone, and transparent with the storage battery 400 in the second time zone. The switch 310 is controlled to connect the light emitting panel 200. Here, the first time zone may be daytime, and the second time zone may be nighttime. Alternatively, the switching control unit 311 has a brightness sensor inside, and controls the switch 310 to connect the solar panel 100 and the storage battery 400 during a period in which the brightness is equal to or greater than the threshold value. In a small period, the switch 310 may be controlled to connect the storage battery 400 and the transparent light emitting panel 200.

  The LED control unit 320 controls the light emission of the transparent light emitting panel 200 when the switch 310 connects the solar panel 100 and the storage battery 400. For example, the LED control unit 320 controls the light emission mode (lit, blinking, or extinguished) for each group of all LEDs 230 or related LEDs 230.

  Furthermore, a method for manufacturing a solar integrated display panel system will be described.

  FIG. 13 is a flowchart showing a method for manufacturing the solar integrated display panel system.

First, the creator creates line drawing data indicating desired symbols to be drawn on the solar panel 100 and the transparent light emitting panel 200 (S11). Next, the arrangement position of the LED 230 on the transparent panel 210 and the shape of the transparent electrode pattern 220 for connecting the LED 230 are determined along the pattern indicated by the line drawing data (S12), and the mask corresponding to the shape The transparent electrode pattern 220 is formed on the transparent panel 210 using a mask (S13), and the LED 230 is surface-mounted on the transparent panel 210 (S14), thereby manufacturing the transparent light-emitting panel 200 .

  Further, the shape and film thickness of the protective film are determined for each color of the line drawing data (S15), and a protective film having the determined shape and film thickness is formed on the solar panel (S16). To manufacture.

  Finally, the panel unit 10 (solar integrated display panel) including the solar panel 100 and the transparent light emitting panel 200 is assembled (S17), and the controller 300 and the storage battery 400 are connected to assemble the solar integrated display panel system.

  According to this manufacturing method, the design of the solar panel 100 and the transparent light emitting panel 200 can be matched by applying one line drawing data to the solar panel 100 and the transparent light emitting panel 200 in common.

  As described above, according to the solar integrated display panel system in the present embodiment, the brightness (brightness) of the panel unit 10 can be improved and the power consumption can be reduced. Electricity charged in the daytime can be used at night, and maintenance costs can be reduced.

  In addition, the design of the solar panel 100 can be formed with extremely high definition, and various designs can be formed on the surface of the solar panel. Moreover, the shading by a design can be suppressed and the reduction in the power generation efficiency of the solar panel due to the presence of the design can be minimized.

  Hereinafter, modified examples of the solar integrated display panel system 1 in the present embodiment will be described.

  (1) The solar panel 100 may be configured by a plurality of solar modules 110 combined in a planar shape, or may be configured by a single solar module 110.

  (2) The LED control unit 320 may cause the LED 230 to emit light statically by constantly applying a DC voltage, or may dynamically emit light by applying a pulsed DC voltage. In the case of dynamically emitting light, the luminance of the LED 230 can be adjusted by adjusting the pulse width and pulse frequency. For example, the luminance can be changed according to the night time zone.

  (3) The light emission color of the LED 230 may be the same color as the design color or a different color.

  (4) The LED controller 320 may dynamically change the LED 230 emission color. For example, three LEDs corresponding to the three primary colors of red, green, and blue may be used as light emission units, the light emission units may be arranged along a pattern, and one or more LEDs in the light emission units may be selectively emitted.

  (5) A plurality of layers (light emitting layers) including the transparent electrode pattern 220 and the LEDs 230 on the surface of the transparent light emitting panel 200 may be formed via an insulating film. In this case, for example, the first light emitting layer and the second light emitting layer can have different designs or different colors.

  The solar integrated display panel system of the present invention is suitable for sign panels such as billboards, guidance display plates, and signboards.
