In the case of the conventional edge light panel as described above, since only the front portion of the panel, that is, the photographic film or other appropriate translucent display sheet portion is illuminated, The edge portion of the panel, which is bordered, becomes dark and inconspicuous compared to the brightness of the display sheet portion. And in the case of such an edge light panel, since the front part is made of a transparent material, it cannot play a bordering role at all.

In other words, for example, in the case of a picture, it is said that the value of the picture is enhanced based on the selection of the frame that accommodates the picture. Therefore, in the case of the panel, the visibility of the display object can be enhanced based on the bordering property, and at the same time the value can be enhanced.

However, in the case of the existing edge light panel, because the front part is formed of a transparent material, such an effect is to increase the visibility and value of the display object based on the bordering property. Was totally unexpected.

  The present invention aims to provide a novel edge light panel that is very unique and interesting in that it has an illuminating action that is raised not only on the surface of the panel but also on its four peripheral edges. In this way, the problems in the conventional edge light panel as described above are solved.

The invention according to claim 3 as described in claim 1 or claim 2 in all four sides of the groove 2 formed in a rectangular frame shape to constitute a strip-like light source 4 to accommodated The edge light panel is used as an embodiment.

According to the present invention, as described in claim 4 , as a means for diffusely reflecting the light irradiated in the panel substrate 1 to irradiate the front side of the panel substrate 1, a V-shaped groove 5a is formed on the entire front surface. The edge light panel according to any one of claims 1 to 3 , wherein the light guide reflection plate 5 is formed so as to be vertically and horizontally cut in a shape.

According to the present invention, as described in claim 5 , the V-shaped groove 5a is engraved in a fine mesh shape by intersecting the longitudinal groove group and the transverse groove group, and the engraving interval is set. The edge light panel according to claim 4, wherein a portion near the strip light source 4 is made relatively wide and a portion far away from the light source reflector 5 is configured so as to narrow the interval.

The invention as described in claim 6, the degree to which the size of the front plate 6, equal to or panel substrate 1, it is possible to hide the rectangular frame-shaped groove 2 formed at least on the panel substrate 1 The edge light panel according to any one of claims 1 to 5 , which is configured to have a size of, is an embodiment.

According to the present invention, as shown in claim 7 , a required display portion 1a indicated by a concavo-convex line is engraved near the edge of the panel substrate 1 so as to cause irregular reflection. The edge light panel according to any one of claims 1 to 6 , wherein the display unit 1a is displayed brilliantly based on an irregular reflection effect of irradiated light.

The present invention has a configuration as described in claim 1 , that is, a concave groove 2 having an opening on one side surface at the position of the inner ring slightly near the outer peripheral edge of the panel substrate 1 made of transparent material having a rectangular shape. Are formed in such a manner that the bottom 2a portion of the concave groove 2 is carried by the plate thickness portion of the panel substrate 1, and the four peripheral edges of the panel substrate 1 are formed. A tapered reflection peripheral surface 3 for irregularly reflecting the irradiated light is formed at the back side ridge corner, and the required number of LEDs 4a are formed in the above-described concave groove 2 in a state of being connected in series with the strip-shaped substrate 4b. The strip-shaped light sources 4 and 4 are arranged so as to be symmetrical vertically and horizontally and the light emitting surface thereof is directed toward the center of the panel substrate 1. A guide that is large enough to cover the entire groove 2 A transparent material front plate 6 having a rectangular shape for sandwiching a reflection plate 5 and sandwiching a photographic film or other appropriate translucent display sheet 7 is detachable from the front surface of the panel substrate 1. Since the non-transparent portion 6b is formed on the peripheral portion of the front plate 6 so that the presence of the band-like light source 4 described above is not visible from the front side, a very unique edge light. Panels will be provided.
That is, as shown in FIG. 10, in addition to the translucent illumination M for the translucent display sheet portion, a bright illumination N as if bordering the four peripheral edges of the panel substrate 1 is formed. Moreover, since the said brilliant illumination N is based on irregular reflection, strong volatility will arise. Accordingly, the presence of the brilliant illumination N as if bordering the four peripheral edges of the panel substrate 1 appears in a contour surrounding the outer portion of the translucent display sheet to be displayed. Thus, an original function and effect that does not have a conventional effect such as emphasizing the display is achieved.

  In particular, a concave groove 2 having an opening surface on one side is formed in a rectangular frame shape parallel to the outer peripheral edge of the panel substrate 1 at the position of the inner ring slightly near the outer peripheral edge of the transparent material panel substrate 1 having a rectangular shape. At the same time, since the bottom 2a portion of the concave groove 2 is formed to be borne by the plate thickness portion of the panel substrate 1, “the light emitted from the LED 4a can be transmitted to the four peripheral edges of the panel substrate 1 made of transparent material. Thus, it is possible to form a continuous portion for light transmission in the fitting portion of the LED in a very rational and simple form.

The present invention adopts the embodiment as described in claim 2 , that is, as a means for attaching the strip-shaped light source 4 to the inside of the concave groove 2, the strip-shaped light source mounting bent plate portion at the end of the heat-dissipating flat plate portion 8 a. The heat radiating plate 8 formed by bending 8b at a right angle is used, and the heat radiating plate 8 is fixed to the back surface of the light guide reflecting plate 5 with the bent plate portion 8b protruding into the groove 2. In order to enhance the heat radiation property of the heat radiating flat plate portion 8a by attaching the band light source 4 in close contact with the bent plate portion 8b and minimizing the overlap between the heat radiating flat plate portion 8a and the light guide reflection plate 5. By forming the rectangular cutout portions 5b and 5b in the light guide reflection plate 5, the heat generated by each LED 4a in the strip light source 4 is released to the outside through the heat dissipation plate 8. . Therefore, it is possible to prevent unexpected occurrences such as thermal deformation of the panel itself due to heat generated from the LEDs 4a.

The present invention adopts an embodiment as set forth in claim 3 , that is, by mounting the strip light source 4 on all four sides of the concave groove 2 formed in a rectangular frame shape, Even if the size of the light panel is a large size such as a BO size, for example, a uniform amount of light is distributed over the large light-transmitting display sheet displayed on the light panel. Sexual effects will be achieved.

The present invention adopts an embodiment as described in claim 4 , that is, as means for irregularly reflecting the light irradiated in the panel substrate 1 and irradiating the front side of the panel substrate 1 over the entire front surface. By using the light guide reflection plate 5 configured to cut the V-shaped groove 5a vertically and horizontally in a fine mesh shape, the light transmitted through the panel substrate 1 is diffusely reflected by the front plate 6 Since it is reflected, the very favorable illumination effect with respect to the translucent display sheet 7 is produced.

The present invention adopts an embodiment as described in claim 5 , that is, the V-shaped groove 5a is engraved in a fine mesh shape by intersecting a vertical groove group and a horizontal groove group. In addition, the engraving interval is relatively wide at the portion close to the strip light source 4, and the distant portion is narrowed to prevent the unevenness of the overall brightness of the backlight-like reflection.

The present invention adopts an embodiment as described in claim 6 , that is, the size of the front plate 6 is equal to that of the panel substrate 1 or at least a rectangular frame-shaped recess formed in the panel substrate 1. By configuring the groove 2 to be of a size that can be concealed, the presence of the concave groove 2 is not transmitted in appearance, and it is as bright as if it borders the four peripheral edges of the panel substrate 1. The presence of the illumination N is located slightly away from the sandwiching surface of the translucent display sheet 7, so that a situation such as lack of exhibition smartness due to both being too close does not occur.

The present invention employs an embodiment as described in claim 7 , that is, a required display portion 1a displayed by uneven lines is formed near the edge of the panel substrate 1 in order to cause irregular reflection. In addition, the display unit 1a such as a logo is displayed in a significantly clear state by configuring the display unit 1a to be brilliantly displayed based on the irregular reflection effect of the light irradiated into the panel substrate 1. I can do it. Therefore, when the display unit 1a is appropriately displayed as an advertisement, an excellent advertisement effect can be produced.

  1 to 3 show the entire edge light panel according to the present invention. In the figure, reference numeral 1 denotes a transparent material panel substrate having a rectangular shape, which is formed of a transparent glass material or a transparent synthetic resin material such as acrylic. 1a is a display part such as a logo engraved near the edge of the panel substrate 1 and is formed in such a manner that the light irradiated into the panel substrate 1 scatters and shines as will be described later. . In other words, the display unit 1a is configured to display the irregular reflection by displaying with irregular lines.

  As shown in FIG. 7 in detail, the panel substrate 1 has a rectangular frame so that a concave groove 2 having an opening surface on the back side is parallel to the outer peripheral edge at a slightly inner ring position near the outer peripheral edge. It is formed in a shape. And the important point of the said ditch | groove 2 is that the whole front side of the said panel board | substrate 1 is a continuous state (it is an edge of four circumferences from a center part) by forming in a bottomed shape without penetrating the panel board | substrate 1. In other words, it is configured to be a continuous state up to the edge portion). That is, as shown in FIG. 3, the concave groove 2 has a bottom 2 a portion that bears a plate thickness portion on the front side of the panel substrate 1, so that the bottom 2 a functions as a “continuous portion”. It is important to form in various forms.

  The presence of the above-described concave groove 2 fits an LED light source to be described later for light irradiation toward the central portion of the panel substrate 1, and the light emitted from the LED light source is not hindered by the fitting portion. It is intended to maintain continuity for light transmission to the fitting portion so that it can be transmitted to the four peripheral edges of the panel board 1 made of transparent material. Any means other than providing the concave groove 2 may be employed.

  In addition, even if it forms the above-mentioned ditch | groove 2 so that the front side may be made into the opening surface with respect to the panel board | substrate 1, there exists the same effect | action, and this invention can also be implemented with such a form. Let's say.

  Furthermore, an important point in the formation of the panel substrate 1 described above is that a tapered reflection peripheral surface 3 having a function of causing irregular reflection of light is formed by cutting back-side ridge corners of the four peripheral edges based on diamond processing. There is in point to do. The taper angle of the tapered reflective peripheral surface 3 is about 45 degrees, which is optimal for reflecting light toward the front side, but is not limited thereto. .

  In addition, the tapered reflective peripheral surface 3 is formed on the basis of diamond processing as described above, so that the tapered reflective peripheral surface 3 becomes rough and light based on the action described below. This is because the reflection is irregularly reflected to enhance the glitter. Therefore, the formation of the tapered reflective peripheral surface 3 is not limited to diamond processing, and there is no limitation on the processing means as long as a surface that allows irregular reflection is formed.

  Reference numeral 4 denotes a strip-shaped light source formed by arranging a required number of LEDs (light emitting diodes) 4a in a state of being arranged in series on the strip-shaped substrate 4b (see FIG. 8 for details), and in the illustrated embodiment, as described above. Are accommodated in two places, that is, an upper side portion and a lower side portion of the concave groove 2 formed in a rectangular frame shape, and the other two side portions accommodate energization wirings 4c for the strip-like light source 4 positioned above and below. In addition, a current-carrying jack (not shown) is provided at a required portion of the side edge of the panel substrate 1 so as to supply electricity to the belt-like light source. In addition, you may comprise the said electricity supply so that an external connection may become unnecessary using a battery.

  And it is an accommodation form with respect to the inside of the concave groove 2 of the above-mentioned strip | belt-shaped light source 4, This is the state (refer FIG. 3) in which the light emission surface turned to the inner side of the panel board | substrate 1, ie, a transparent material. It is important that the optical axis advances inward of the panel substrate 1. It should be noted that, in order to make it easy to understand in the drawings, the tip portion of each LED 4a and the inner wall of the concave groove 2 are drawn away from each other, but in actuality, they are in contact with each other. It is preferable from the viewpoint of light transmission. In the present invention, it is a principle to accommodate in such a contact state.

By the way, in the illustrated embodiment, the belt-like light source 4 is accommodated in both the upper and lower portions, but it may be configured to be accommodated in both the left and right portions. The important point is that the band-like light sources 4 are provided so as to face each other.

  Furthermore, you may comprise so that the strip | belt-shaped light source 4 may be accommodated in all the four sides of the ditch | groove 2 currently formed in the said rectangular frame shape. This is a preferable mode when the size of the edge light panel to be implemented is a large size such as a BO size. That is, in the case of a large size, it is preferable to adopt such a form in order to allow a sufficient amount of light to reach the entire panel substrate 1.

Reference numeral 5 denotes a light guide reflection plate stretched on the back side of the panel substrate 1 and is large enough to cover the entire concave groove 2 formed in a rectangular frame shape on the back side of the panel substrate 1 described above. It presents a rectangular shape with Therefore, as described above, the strip-shaped light source 4 housed in the concave groove 2 is configured to be kept in a concealed state based on the extension of the light guide reflection plate 5.

The light guide reflection plate 5 described above is a so-called backlight action, that is, the optical axis of the band-like light source 4 transmitted through the panel substrate 1 is received and diffusely reflected on the front side thereof, and the front surface of the panel substrate 1 It is for irradiating the side. Therefore, at least the front side where the irregular reflection occurs is made silvery or mirror-like, so that a metal material or a synthetic resin material that performs the light reflection function well is subjected to silver plating for reflection or the like. It is made up of

By the way, although it is an above-mentioned light guide reflective plate, the following structures are taken as a means for performing irradiation with respect to the front side of the panel board | substrate 1 favorably and efficiently. That is, the V-shaped groove 5a as shown in FIG. 6 is engraved vertically and horizontally in a fine mesh shape as shown in FIG. The diffused reflection is performed so that the front side of the panel substrate 1 is irradiated.

  Further, the V-shaped groove 5a is engraved in a fine mesh shape by intersecting the vertical groove group and the horizontal groove group. The near part may be relatively wide, but the part far from this, i.e., the central part, is narrowed in the interval, thereby improving the brightness due to the dense diffused reflection and improving the overall brightness of the backlight-like reflection. It is preferable to configure so that unevenness does not occur. (See Figure 6)

  A transparent material front plate 6 having a rectangular shape is detachably attached to the front surface of the panel substrate 1. A translucent display sheet 7 such as a photographic film is displayed by being sandwiched between the panel substrate 1 and the front plate 6. Reference numeral 6 a denotes a headed screw for detachably fixing the front plate 6, and is configured to be fixed by screwing and fastening at four corners of the front plate 6.

  Further, as shown in FIG. 4, the front plate 6 is formed with a non-transparent portion 6b based on coating or other appropriate means on the peripheral portion thereof as shown in FIG. It is configured so that it cannot be seen. Accordingly, the size of the front plate 6 is equal to the panel substrate 1 or has a size enough to hide the rectangular frame-shaped concave groove 2 formed in the panel substrate 1. It is set.

  The edge light panel according to the present invention has the above-described configuration, and the lighting action as shown in FIG.

  That is, as shown in the figure, the light is emitted toward the inner side of the panel substrate 1 based on the lighting of the strip light sources 4 and 4 provided near the upper and lower edges of the panel substrate 1. The optical axis hits the light guide reflection plate 5 and is irregularly reflected, which is transmitted to the front side of the edge light panel as shown in FIG. Therefore, based on the transmission, a brilliant action is exerted on the translucent display sheet 7 sandwiched in front of the front plate 6, and a display effect in a bright and vivid state can be obtained.

  Further, a part of the optical axis generated based on the lighting of the strip light sources 4 and 4 reaches the edge of the peripheral edge of the panel substrate 1. That is, the groove in which the strip-like light sources 4 and 4 are accommodated is provided in such a form that the back side is an opening surface at the position of the inner ring slightly near the outer peripheral edge of the panel substrate 1, and the groove 2 Is formed in such a manner that the bottom 2a portion is borne by the plate thickness portion on the front side of the panel substrate 1, so that the above-mentioned optical axis does not stop at the concave groove 2 portion, and the bottom portion Based on the continuity of the 2a formation part, it will reach | attain the edge part of the periphery of the panel board | substrate 1. FIG.

  The optical axis that has reached the peripheral edge of the panel substrate 1 as described above hits the tapered reflective peripheral surface 3 formed based on diamond processing so as to cut the back side corners of the four peripheral edges of the panel substrate 1, The irregularly reflected optical axis is transmitted to the front side of the panel substrate 1. Therefore, the four peripheral edges of the panel substrate 1 have a glittering effect as if the edge lighting was performed.

  By the way, as shown in FIG. 13, the conventional panel is configured so that the portion for accommodating the light source A is accommodated in the accommodating groove C formed by penetrating the end of the panel substrate B (patent). Document 2 also takes such a form.) The light emitted from the light source A is blocked by the accommodation groove C and cannot be irradiated to the edge D of the panel substrate B. Such an operation unique to the present invention such as “framing illumination light emission on the four peripheral edges of the panel substrate 1” cannot be performed.

  Based on the operation as described above, the edge light panel according to the present invention, as shown in FIG. 10, framing the translucent illumination M on the translucent display sheet portion and the four peripheral edges of the panel substrate 1. Such two bright illuminations N are achieved, and both the illuminations are based on the irregular reflection as described above, so that it is assumed that strong volatility occurs. Therefore, in particular, the glittering illumination N as if bordering the four peripheral edges of the panel substrate 1 appears in a contour surrounding the outer portion of the translucent display sheet 7 that is the display object. It will act to emphasize the display of the part. Further, the display unit 1a also displays a glittering display based on the irregular reflection.

  FIGS. 11 and 12 show a second embodiment of the present invention. As the above-described “containment form in the concave groove 2 of the strip-shaped light source 4”, the strip-shaped light source 4 is thermally dissipated. This means is added.

  In the figure, 8 is a heat radiating plate made of a material having high heat transfer properties such as aluminum, for mounting a strip-shaped light source formed by bending a flat plate portion 8a for heat dissipation and an end portion of the flat plate portion 8a at a right angle. It consists of a bent plate portion 8b. And the said heat sink 8 is fixed in the state located in the back side of the light-guide reflecting plate 5 in the state which made the described strip | belt-shaped light source fixing bending board part 8b penetrate | invade in the already-described recessed groove 2. FIG. It is constituted as follows. Further, in order to enhance the heat dissipation performance of the heat radiating flat plate portion 8a, in order to minimize the overlap for bonding and the like between the heat radiating flat plate portion 8a and the light guide reflector 5 (to minimize it). ), Rectangular cutout portions 5b and 5b are formed in the overlapping portion of the light guide reflection plate 5.

  Then, the strip-shaped light source 4 formed by arranging the required number of LEDs 4a as shown in FIG. 8 on the strip-shaped substrate 4b and connecting them in series is fixed to the curved plate portion 8b so as to be in close contact with the curved plate portion 8b. As a result, the heat generated from each LED 4a is transmitted to the outside through the heat radiating plate 8 and a diverging action is exhibited. Thereby, it is configured to prevent the occurrence of thermal deformation of the panel itself due to the heat generated from each LED 4a and the deterioration of the lifetime of the LED itself.
