Description

  The present invention is a backlit signboard, which is a signboard capable of producing various effects such as a neon sign while transforming into a normal signboard in the daytime mode and a neon sign-like signboard in the night mode. In the mode, the present invention relates to an internally illuminated signboard apparatus that can produce a gradation effect on advertising characters, figures, etc., and has a great energy saving effect and maintenance-free at the same price as a conventional signboard.

  Conventionally, many advertising media using neon tubes (neon signs) have been used. This is a feature of the neon tube, which can emit light with high brightness, and can emit light in various colors by changing the components of the gas to be sealed. This is because the effect of the flashing of the flow can be exerted, and as a result, the eye catching effect is extremely large due to the synergistic effect of high brightness, free color development, flashing, etc. As a usage, the neon tube is processed like a one-stroke drawing to express characters and logo marks (used frequently in pachinko parlors), or a neon tube is installed in a milky white light-transmitting panel. , An internally illuminated signboard (such as a boutique signboard for boutiques, etc.) capable of dimming (coloring) the entire panel without showing the neon tube.

  By the way, the shortcomings of the neon sign are that (a) a one-stroke neon tube appears blatantly in the daytime, which impairs the advertising effect. (B) Furthermore, enormous power is consumed because of the heavy use of neon tubes. (C) A large amount of money is required for installation and maintenance. (D) In particular, the so-called “buzzy and flashy” neon situation is that the installation standards are becoming stricter from the viewpoint of environmental protection such as cities.

  On the other hand, the current status of backlit / running signboards (interior-lit signboards) is a signboard that is installed on the wall surface of the building or at the top of the entrance and exits brightly by the light source that is loaded inside the signboard at night. As the main, fluorescent tubes are used. Recently, an edge light panel has been used in which an LED (Light-emitting diode) is attached to a side edge of an acrylic panel and the surface of the acrylic is emitted. These conventional internally-lit signboards have been made for the purpose of brightly illuminating advertisements and messages drawn on the board. Unlike the neon sign, the board does not include elements such as changes or effects, and it is a simple illuminated billboard function.

The internal lighting signboard has a simple structure and a simple construction. Moreover, it is always posted in the same state (day and night). Furthermore, the maintenance cost is lower than that of neon. In particular,
Those using LEDs have the advantage of reducing power consumption by half. Disadvantages are the lack of directing function like neon, so the eye catching effect is inferior, and this internally illuminated signboard is widely used, so it is difficult to differentiate from other signboards and the advertising effect is low ing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a first embodiment will be described with reference to FIGS. The main configuration of the present invention includes a display body P, a toning light source unit 7 and a light source control unit 76. The display body P includes an advertisement face body 1, a translucent resin plate 21, and a light shielding face body 4. The advertising plane 1 includes an achromatic transparent advertising surface 11, a chromatic transparent advertising surface 12, a red transparent advertising surface R12, a green transparent advertising surface G12, a blue transparent advertising surface B12, and a translucent advertising. An ink layer (a film of about several microns) or a cutting layer (a resin layer of about 50 to about 100 microns) comprising the surface 13. The chromatic color transparent advertising surface 12 is an advertising surface that transmits chromatic colors such as yellow, purple, etc. other than red, green, and blue.

More specifically, each of the red transparent advertising surface R12, the green transparent advertising surface G12, and the blue transparent advertising surface B12 is an example of a subordinate concept in the chromatic transparent advertising surface 12, and The chromatic color transparent advertising surface 12 (for example, yellow) having a specific color is displayed in relation to the red, green, and blue colors of the RGB three primary color LEDs 73 of the color light source unit 7. It is displayed in a color that affects at least two colors of the RGB three primary color LEDs 73.
The translucent advertising surface 13 is the surface of the translucent body 2 itself, and the daytime mode (a mode in which an electric signboard can be seen in the daytime state regardless of time) is applied to the light shielding surface body 4. It keeps the state where the cut out characters cannot be seen.

  In the present specification, the achromatic color transparent advertising surface 11 is an advertising surface having a color ranging from white to gray except black, and can be visually recognized as a part of the advertising surface in the daytime mode and the night mode (time This is a mode in which the electric signboard can be seen in a dark state regardless of the above.) For example, the RGB three primary color LEDs 73 of the toning light source unit 7 may transmit appropriate colors as an advertisement surface. Specifically, a character, a figure, a pattern, or the like is provided on the surface of the translucent body 2 in white or gray. 2 to 4, a character “A” is drawn, which is white or gray, the same as the surface of the translucent resin plate 21, and is surrounded by a black border 11 a. In the daytime mode, as shown in FIG. 4 (4B) and FIG. 5, the white character “A” with the border 11a can be visually observed. In the night mode, all colors such as red, green, blue, and white of the light source of the RGB three primary color LEDs 73 are displayed as an advertising surface because of the achromatic color transparency.

  As shown in FIGS. 6 (6A), (6B), and (6C), each of the red transmissive advertising surface R12, the green transmissive advertising surface G12, and the blue transmissive advertising surface B12 is in the daytime mode. As shown on the left side of the figure, red, green, and blue can be seen as the advertisement surface. In the night mode, the RGB three primary color LEDs 73 transmit red, green, and blue colors to the advertisement surface as shown on the right side of the figure. . Specifically, the red transparent advertising surface R12, the green transparent advertising surface G12, and the blue transparent advertising surface B12 on the surface of the translucent resin plate 21 are red, green, and blue, respectively. Or a pattern etc. are provided. In FIG. 6 (6A), a red letter “B” is drawn on the red transparent advertising surface R12, and the red letter “B” can be visually observed in the daytime mode. In the night mode, because of the red transparency, the RGB three primary color LEDs 73 are displayed as advertisement planes corresponding to only red for all colors such as red, green, blue and white.

  In FIG. 3 (3C), a green letter “C” is drawn on the surface of the green transparent advertising surface G12, and the green letter “C” can be visually recognized in the daytime mode. In the night mode, because of the green transparency, the red, green, blue and white colors of the RGB three primary color LEDs 73 are displayed as advertisements corresponding to only green (FIG. 6 [6B]). Further, in FIG. 3 (3C), a blue letter “D” is drawn on the surface of the blue transparent advertising surface B12, and the blue letter is displayed in the daytime mode as shown in FIG. 6 (6C). The blue letter “D” is visible. In the night mode, because of the blue transparency, the RGB three primary color LEDs 73 are displayed as advertisement planes corresponding to only blue for all colors such as red, green, blue and white.

  The advertising face 1 is integrated with the translucent resin plate 21. The advertising face 1 is configured as a printing surface on the translucent resin plate 21 or is formed by sticking a cutting sheet on the translucent resin plate 21. The printed thin film-like sheet is often stuck on the translucent resin plate 21. Moreover, although the translucent resin plate 21 is a relatively thick material, it may be printed directly on the translucent resin plate 21. The translucent resin plate 21 has a relatively thick plate thickness. Specifically, the translucent resin plate 21 has a thickness of about 3 mm to about 10 mm. Due to the presence of the translucent resin plate 21, even in the daytime reflected light, in the daytime mode, it is configured to maintain a state where characters, figures, and the like cut out on the light shielding face 4 cannot be seen, and the night mode. Then, it is configured to function as an advertising surface while maintaining a state in which characters, figures, and the like cut out on the light-shielding surface body 4 by the light source of the RGB three primary color LEDs 73 can be seen.

  The translucent resin plate 21 is preferably white or white with a slight addition of other colors such as yellow to white, and has a whiteness (ASTM E313) of about 60 to about 80%. preferable. When the whiteness is less than 60%, even if light is emitted from the back side of the semi-transparent body 2 by the RGB three primary color LEDs 73, characters, figures, etc. cut out on the light-shielding face body 4 are visible on the surface of the semi-transparent resin plate 21. It becomes difficult. Further, when the whiteness exceeds 80%, characters, figures, and the like cut out on the light-shielding face 4 are transparent from the surface of the translucent resin plate 21 when the light source of the RGB three primary colors LED 73 is turned off and also in the daytime mode. Since it becomes easy to see, it will be in an unpreferable state.

  The light shielding surface 4 is provided with a transparent cutout 41 for characters, figures and the like. In the night mode, any color other than the transparent cut-out portion 41 such as characters and figures is dark black or nearly black and no longer advertised regardless of the color of the RGB three primary color LEDs 73. Yes. In particular, the light shielding face 4 functions as a pair with the advertising face 1 in which the translucent resin plate 21 is sandwiched. That is, as shown in FIG. 3 (3B), the achromatic transparent advertising surface 11, the chromatic transparent advertising surface 12, the red transparent advertising surface R12, the green transparent advertising surface G12, and the blue transparent A transparent cutout 41 having a shape equivalent to a desired character or graphic corresponding to each advertising surface of the sex advertising surface B12 is provided. In particular, the achromatic color transparent advertising surface 11, the chromatic color transparent advertising surface 12, the red transmissive advertising surface R12, the green transmissive advertising surface G12, and the blue transmissive advertising surface B12, respectively. Those having specific shapes are referred to as achromatic transmission cutout holes 41a, chromatic transmission cutout holes 41b (yellow, etc.), red transmission cutout holes R41, green transmission cutout holes G41, and blue transmission cutout holes B41.

  As the achromatic transparent advertisement surface 11, a white character “A” is drawn in FIG. 3 (3C). As shown in FIG. 3 (3B), an achromatic transparent cutout hole 41a having the same size is provided for the outer shape of the white character. Thus, in the daytime mode, the white character “A” can be visually observed. In the night mode, all colors such as red, green, blue, and white of the RGB three primary color LEDs 73 are displayed as an advertising surface because of the achromatic color transparency. At this time, as shown on each right side of FIGS. 5 (6A) to (6C), a so-called gradation effect can be obtained around the display “A”.

  The configuration for obtaining this gradation effect will be described in detail. Although the shape is the same size as the white character “A”, the size of the characters is almost the same in practice. In this way, when the RGB three primary color LEDs 73 are lit, the “A” character portion of the achromatic transparent cutout hole 41a is hit by a strong light source, but “A” displayed on the achromatic transparent advertising surface 11 is displayed. The outline (outer edge) of the character (bold) is less blurred, that is, it can obtain a blurred state, that is, a gradation effect, and avoid flashy displays such as neon signs. It is possible to provide a deep character or graphic display.

  This gradation effect will be described in detail. When the RGB three primary color LEDs 73 are turned on, as shown in FIG. 4 (4A), the light source amount per unit area from the achromatic transparent cutout hole 41a is 100% lightness in the vertical direction, but the semi-transparent. Due to the thickness of the resin plate 21, the amount of the light source irregularly reflected also around the “A” character portion of the achromatic transparent cutout hole 41a is reduced linearly to 0%. As a result, the image is gradually blurred and a gradation effect can be obtained. The inclination line of the light leaking at an inclination is defined as n. A gradation peripheral line m is generated by the inclined line n.

  The red transparent advertising surface R12 is depicted with a red letter “B” in FIG. 3 (3C). For the red letter “B”, a red transmission cutout hole R41 is provided as a transmission cutout 41 of the same size. Thereby, in the daytime mode, the red letter “B” is visible. In the night mode, because of red transparency, as shown in FIG. 6 (6A), the RGB three primary color LEDs 73 are displayed as an advertisement screen corresponding to only red for all colors such as red, green, blue, and white. At this time, a gradation effect having a blurred shape as a peripheral line m can be obtained around the display “B”.

  Further, as the green transparent advertising surface G12, a green letter “C” is drawn in FIG. 3 (3C). A blue transmissive cutout hole G41 having an equivalent size is provided for the green letter “C”. Thereby, in the daytime mode, the green letter “C” is visible. In the night mode, because of green transparency, as shown in FIG. 6 (6B), as the advertising surface corresponding to only green for all colors such as red, green, blue and white of the light source of the RGB three primary color LEDs 73, Is displayed. At this time, a gradation effect having a blurred shape as a peripheral line m is obtained around the display “C”.

  As the blue transparent advertising surface B12, a blue letter “D” is drawn in FIG. 3 (3C). For the blue letter “D”, a green transmission cutout hole B41 of the same size is provided. Thereby, in the daytime mode, the blue letter “D” is visible. In the night mode, because of the blue transparency, the advertisement surface is displayed corresponding to only blue for all colors such as red, green, blue, and white of the light source of the RGB three primary color LEDs 73. At this time, a gradation effect as a blurred shape as the peripheral line m can be obtained around the display “D”.

  2 (2A), 3 (3A), and (3C), when the chromatic color transmissive advertising surface 12 is assumed to be yellow, the RGB three primary color LEDs 73 of the toning light source unit 7 are assumed to correspond to red and green. If the red light is lit, the red transparent advertising surface R12 is displayed in red, and the yellow chromatic transparent advertising surface 12 is displayed in dark red. When the green light is lit, the green transparent advertising surface G12 is displayed in green, and at the same time, the yellow chromatic transparent advertising surface 12 is displayed in dark green. That is, the chromatic color transparent advertising surface 12 may be displayed in a composite manner corresponding to some colors of the RGB three primary colors LED 73 of the toning light source unit 7. In addition, when the red and green light sources of the toning light source unit 7 are turned on simultaneously, they are displayed in yellow.

  Further, a part of the chromatic color transparent advertising surface 12 including red, green, and blue having desired characters or figures (for example, a part thereof includes two or more colors such as chromatic purple and yellow). And an achromatic transparent advertising surface 11 having an outer edge such as a desired character or graphic, and may be configured as an advertising surface 1 of an ink layer or a cutting layer. In addition, at least two of the red transparent advertising surface R12, the green transparent advertising surface G12, and the blue transparent advertising surface B12 are necessarily provided. That is, in the case of the red transparent advertising surface R12 and the green transparent advertising surface G12, in the case of the red transparent advertising surface R12 and the blue transparent advertising surface B12, the green transparent advertising surface G12 and the blue transparent advertising surface B12. This is the case.

  Furthermore, FIG. 7 will be described as an additional example of the first embodiment of the present invention. That is, the display contents of “E”, “F”, and “G”. While the surface side of the translucent resin plate 21 is left as it is, a night-type transparent cutout hole 41c having a shape equivalent to a desired character or figure is formed in the light-shielding surface 4 on the rear side of the translucent resin plate 21. Yes. As a result, in the daytime mode, as shown in FIGS. 1, 2 (2A), 3 (3A) and 7 (7B), (7C), (7D), characters and the like are not visible at all. Only the leaf pattern is visible. In the night mode, as shown in FIG. 7, all colors such as red, green, blue, and white of the light source of the RGB three-primary-color LED 73 are displayed as the advertising surface because of the chromatic color transparency on the chromatic color transparent advertising surface 12. The At this time, since the leaflet pattern corresponds to the light shielding surface of the light shielding surface body 4, even if the light source of the RGB three primary colors LED 73 is turned on, it becomes a black color or a dark color close to black and becomes an advertising surface.

  The power supply circuit configuration of the RGB three primary color LEDs 73 is configured as a toning light source unit 7. Specifically, a large number of RGB three primary colors LEDs 73 are provided from the LED lighting power source 71 via the wiring part 72 of the DC circuit. As an example, three, four or six or seven RGB three primary color LEDs 73 are connected in series to a 12 V or 24 V LED lighting power source 71 via a control resistor or the like. The RGB three primary color LEDs 73 are adjusted in red, green, and blue by adjusting the red LED current controller R74, the green LED current controller G74, and the blue LED current controller B74 in the light source controller 76 and the LED brightness controller 75, respectively. The color adjustment is performed while the blinking adjustment is performed. This configuration is applied to the first to fourth embodiments of the present invention. The toning light source unit 7 is a light source unit of a row lamp (backlight) method or a light guide plate method. The RGB three primary color LEDs 73 can be integrated or used separately (red, green, and blue), and a desired effect can be produced by appropriately adjusting the dimming.

  Next, 2nd Embodiment of this invention is described based on FIG. 8 (8A). In particular, a member provided with a transparent resin plate 31 superimposed on the translucent resin sheet 22 is provided. That is, it is converted to the translucent resin plate 21 of the first embodiment. The translucent resin sheet 22 has a relatively thin plate thickness. Specifically, the translucent resin sheet 22 has a thickness of about 1 mm. The transparent resin plate 31 has a relatively thick plate thickness. Specifically, the transparent resin plate 31 has a thickness of about 3 mm to about 10 mm. The thickness t of the translucent resin sheet 22 and the transparent resin plate 31 of the second embodiment is configured as a relatively thick material. Other configurations are the same as those in the first embodiment, and a description thereof will be omitted. In addition, as a modification, as shown in FIG. 8 (8B), the translucent resin sheet 22 and the transparent resin plate 31 are separated by an interval h. Furthermore, the above-described thickness t is increased. By increasing the interval h, a better gradation effect can be obtained. That is, the blur width can be increased.

  A third embodiment of the present invention will be described with reference to FIG. In particular, a translucent resin sheet 22 and a transparent resin sheet 32 spaced apart from the translucent resin sheet 22 by a predetermined distance h are provided. That is, the translucent resin plate 21 of the first embodiment is converted to the transparent resin sheet 32. The transparent resin sheet 32 has a relatively thin plate thickness. Specifically, the transparent resin sheet 32 has a thickness of about 1 mm inside or outside. Other configurations are the same as those in the first embodiment, and a description thereof will be omitted. In this case, by increasing the distance h, the blur width can be increased and a better gradation effect can be obtained as in the modification of the second embodiment.

  A fourth embodiment of the present invention will be described with reference to FIG. Chromatic transmissive advertising surface 52 (including a part of chromatic color also exists) including red transmissive advertising surface R52, green transmissive advertising surface G52, and blue transmissive advertising surface B52 having desired characters or graphics. )) And an achromatic transparent advertising surface 51 having an outer edge such as a desired character or figure, and a transparent advertising surface body 5 of a cutting layer (in the present invention, except for an ink layer by printing), A light-shielding advertising face provided with a translucent resin sheet 22 on which the transparent advertising face 5 is stacked, and a small transparent cutout portion 61 that has a shape equivalent to a desired character or figure corresponding to each of the advertising faces and is thin. 6 and a display body Q superimposed on each other, the outer peripheral edge of each advertising surface of the transparent advertising surface body 5 is overlapped on the peripheral edge of the small transparent cutout portion 61 to form an overlapping portion 63, and the display From the rear side of body Q Provided to allow the projection light source of GB three primary colors LED 73, it is lit current adjustably controlling the appropriate RGB of the RGB three primary colors LED 73. In the fourth embodiment, in particular, the light shielding surface 4 can be omitted, and the configuration can be simplified. As a modification, the translucent resin sheet 22 may be converted into a translucent resin plate 21 to be configured. It is simply an increase in strength.

  The operation of the fourth embodiment of the present invention will be described with reference to FIG. 10 (10D). When entering from the transparent advertising face 5 with the light source of the RGB three primary colors LED 73, the light enters the material in an irregular reflection state. This light is reduced and flows outward at 63 overlapping portions. This leaked light is the blur of light and can be obtained as a gradation. Further, in FIG. 11 (11A), a red letter “A” is drawn. Thereby, in the daytime mode, the red letter “A” is visible. In the night mode, due to red transparency and irregular reflection of the overlapping portion 63, only red is supported for all colors such as red, green, blue, and white of the light source of the RGB primary color LED 73 as shown in FIG. 11 (11A). And displayed as an advertising screen. At this time, a gradation effect having a blurry red shape is obtained around the display “A” with the periphery of the overlapping portion 63 as the peripheral line m.

  Furthermore, about FIG. 11 (11B), the green letter "A" is drawn. Thereby, in the daytime mode, the green letter “A” is visible. In the night mode, due to the green transparency and the irregular reflection of the overlapping portion 63, as shown in FIG. 11 (11B), only the green color corresponding to all the colors such as red, green, blue, and white of the light source of the RGB primary color LED 73 is supported. At the same time, a gradation effect with a green blurred shape is obtained around the display “A” with the periphery of the overlapping portion 63 as the peripheral line m.

  Also, in FIG. 11 (11C), a white character “A” is drawn. Thus, in the daytime mode, the white character “A” can be visually observed. In the night mode, due to the achromatic color transparency and the irregular reflection of the overlapping portion 63, as shown in FIG. 11 (11C), the light source of the RGB three primary colors LED 73 is only white for all colors such as red, green, blue, and white. Correspondingly, it is displayed as an advertising surface, and at the same time, a gradation effect with a white blurred shape is obtained around the display “A” with the periphery of the overlapping portion 63 as the peripheral line m. As described above, in the present invention, as a small size, for example, a signboard device capable of dealing with a free size from a small size plate of A-4 size to a large advertising billboard.
