Note that the material and shape of the base sheet 51 are not limited to these. For example, the material may be a hard plastic material such as acrylic resin instead of a rubber material. Also, the base sheet 51 may have a circular shape. Furthermore, the base sheet 51 may be provided with other means for fixing with the sheath 7, such as screw holes, without the rubber magnets. In this case, the exterior 7 side also has screw holes at positions corresponding to the positions of the screw holes on the base sheet 51 side, and the base sheet 51 (light emitting sheet 5) and the exterior 7 are screwed. Instead of the magnetic layer, male and female hook-and-loop fasteners may be provided on the back surface of the base sheet 51 and the surface of the exterior 7 so as to face each other.

FIG. 6 is an enlarged front view of the designable light-emitting device 1 in FIG. 1 taken along line BB and CC.
When the two light-emitting sheets 5A and 5B are placed on top of the design display member 6, the LEDs 50 are arranged vertically within the range of the design translucent member 61 represented by a line having a thickness (width). They are arranged so that a plurality of them are included in one left and right direction.

Here, the operation when the designable light-emitting device 1 is actually used as a sign advertisement will be described.
The moving image reproducing device 2 stores moving image data to be reproduced in advance. Note that the moving image reproducing device 2 may be configured to acquire moving image data from the outside in real time and transmit the data to the transmitter 3 . The moving image reproduction device 2 transmits moving image data to the transmitter 3 . The moving image data is a moving image corresponding to the design (characters, figures, or patterns) of the design translucent member 61 . This moving image is, for example, a moving image in which the letter "B" gradually appears from the upper left, or a moving image in which "three semicircles with different diameters" gradually appear from each end. A video (or a still image) in which figures such as "three semicircles" appear, or figures such as "B", "O", and "three semicircles with different diameters" are bright and other parts are dark. can. In this embodiment, moving image data is used, but the image reproduced by the moving image reproducing device 2 is not limited to this. ) can be used.

The transmitter 3 receives the moving image data transmitted from the moving image reproducing device 2 and converts the received moving image data into light emission pattern data of the LEDs 50 by the moving image data conversion function. The transmitter 3 transmits light emission pattern data to the receiver 4 .

The receiver 4 receives the light emission pattern data transmitted from the transmitter 3, and divides the received light emission pattern data so as to correspond to the two light emission sheets 5A and 5B by the light emission pattern data division function. In this embodiment, the moving image data displayed in the square display area is divided so that the upper half is displayed on the luminous sheet 5A and the lower half is displayed on the luminous sheet 5B. The receiver 4 outputs the divided light emission pattern data to the light emission sheets 5A and 5B, and controls the light emission colors and light emission patterns of all the LEDs 50 . Therefore, the receiver 4 functions as a control device for the luminescent sheet 5 . In this embodiment, the receiver 4 is used as the control device, but the transmitter 3 or the video playback device 2 may be used as the control device.

All the LEDs 50 of the luminous sheet 5 are controlled by the receiver 4 . Then, the LED 50 emits light in the front direction so as to correspond to the light emission pattern data. The light (light rays) emitted by the light emission is diffused inside the design translucent member 61 and is transmitted in the front direction. At this time, the design of the design translucent member 61, which shines evenly and evenly, is clearly visible from the front side (the side where the light-emitting surface can be visually recognized). That is, the receiver 4 executes design emphasizing light emission for controlling light emission of the LEDs 50 so as to emphasize the design of the designable translucent member 61 with a light emission pattern corresponding to the position of the designable translucent member 61 and the design shape. do. In this design emphasizing light emission, only the portions having a design, such as the portion corresponding to the position of the design translucent member 61 and the shape of the design, and the portion performing the effect corresponding to the position of the blank member 62, emit light. The light emission pattern is controlled so that the light does not emit light.

With the above configuration, it is possible to provide a designable light-emitting device that emits light while emphasizing a linear shape representing a character, figure, or pattern, and that has a small number of parts that must be individually produced as a one-off product. .
The designable light-emitting device 1 includes a light-emitting sheet 5 having a plurality of LEDs 50 (light-emitting elements) arranged on its surface, and a designable light-transmitting device formed of a light diffusing material formed in a linear shape representing characters, figures, or patterns. A member 61 and a blank member 62 arranged in an area other than the design translucent member 61 are provided, and the receiver 4 emits design emphasizing light emission by causing the LEDs 50 to emit light so as to correspond to the position of the design translucent member 61. It is a configuration to control. With this configuration, linear shapes representing characters, graphics, or patterns can be made to stand out and emit light. Further, since the LED 50 at the position corresponding to the designable translucent member 61 is not directly visible, the designable translucent member 61 does not look like dots, and the light is diffused within the designable translucent member 61. Since the designable light-transmitting member 61 uniformly emits light, the design of the designable light-transmitting member 61 can be clearly recognized. In addition, compared to the conventional box letters that must be produced according to individual orders even for the housing, since there are fewer parts that must be individually produced as a one-off product, the designable light emitting device 1 can be inexpensive. .

Further, the blank member 62 is formed of a material whose transmittance (transparency) for transmitting light is different from the transmittance (transparency) of the design translucent member 61 . With this configuration, the boundary line between the designable translucent member 61 and the blank member 62 becomes clear, and the design of the designable translucent member 61 can be recognized more clearly. Specifically, by making the blank member 62 an opaque material, only the design translucent member 61 can emit light, and the design can be clearly recognized.

Further, the receiver 4 controls the light emission of the LED 50 by light emission pattern data converted from moving image data. With this configuration, the color and brightness of light emitted from the LEDs 50 can be changed in various ways, and an effect in which the design translucent member 61 changes in various colors and brightness can be realized.

In addition, the receiver 4 controls the light emission of all the LEDs 50 of the plurality of light-emitting sheets 5, and at least part of the designable translucent member 61 (including the designable translucent member 61) is composed of the two light-emitting sheets 5A. , 5B so as to straddle the sheet seam 56 . With this configuration, no matter how large the size of the designable light-transmitting member 61 is, there is no need to prepare one huge light-emitting sheet 5, and a plurality of light-emitting sheets 5 can be arranged side by side. can be done. That is, the designable light-emitting device 1 can be installed in various places, and can be suitably used as an outdoor advertisement.

Since the designable translucent member 61 exists on the sheet joint 56, the light from the LED 50 is diffused within the designable translucent member 61, and the upper portion of the sheet joint 56 is not darkened and is uniform. It can emit light. In particular, the distance between the edge LEDs 50 and the edge 57 of the light-emitting sheet is half the distance between the adjacent LEDs 50, so that the distance between the LEDs 50 in the portion straddling the sheet seam 56 is the same as the distance between the LEDs 50 in other portions. becomes. As a result, the design translucent member 61 at the sheet seam 56 does not become slightly dark or slightly bright, and can emit light uniformly.

In addition, in the light-emitting sheet 5, the edge spacing 55, which is the spacing between the LEDs 50 arranged at the extreme ends in the horizontal and vertical directions and the edge of the light-emitting sheet 5, is 40 to 60% of the light-emitting element spacing 53. have With this configuration, the designable light-transmitting member 61 does not form a shadow due to the sheet seam 56 even at the position overlapping the sheet seam 56, and the designable light-transmitting member 61 can emit light uniformly.

Further, the design translucent member 61 is milky white and has a thickness in the range of 5 mm to 12 mm and a transmittance (total light transmittance) in the range of 30 to 80%. With this configuration, the design of the designable light-transmitting member 61 can be clearly seen from a distance, and the designable light-transmitting member 61 has transparency to the extent that the LED 50 at the position corresponding to the designable light-transmitting member 61 cannot be visually recognized. can.

Further, among the plurality of LEDs 50 provided on the light-emitting sheets 5A and 5B, the LEDs 50 provided at positions facing the rear surface of the design translucent member 61 are caused to emit light, and the other LEDs 50 are not caused to emit light. Only the translucent member 61 emits light clearly and brightly to make the sign stand out, and the design translucent member 61 can be made bright and conspicuous by not causing the LEDs 50 in other portions to emit light. In addition, the LEDs 50 at positions not facing the rear surface of the designable translucent member 61 do not emit light, so that light leaks out from appropriate gaps, etc., and the light-emitting sheets 5A and 5B and the designable translucent member 61 provide effects and visual recognition. Clear visibility can be obtained without disturbing the line shapes representing the desired characters, figures, or patterns. In addition, since the LEDs 50 at positions not facing the rear surface of the translucent design member 61 do not emit light, it is possible to prevent unnecessary power from being used.

In addition, since the back surface of the light emitting sheet 5 is a rubber magnet or a magnetic material is arranged so that the magnetic force is applied to the back surface of the light emitting sheet 5, it can be used by being attracted not only to a flat surface but also to a curved surface or a spherical surface. can be done.

It should be noted that the present invention is not limited to the configurations of the above-described embodiments, and many embodiments can be obtained.
For example, the blank member 62 may be made of a translucent material having a lower transmittance (transparency) than the design translucent member 61 instead of an opaque material. With such a form, the boundary line between the designable translucent member 61 and the blank member 62 can be visually recognized as dimly shining, and the design can be changed. In this case, for example, the LED 50 that emits light in the shape of the designable translucent member 61 emits light so that the brightness gradually decreases toward the edge of the designable translucent member 61 toward the outside. The area around 61 can be dimly illuminated. Further, by setting the light emission pattern of the LEDs 50 at positions corresponding to the blank member 62 , it is possible to perform an effect that gives an impression different from the light emission pattern of the design translucent member 61 . Specifically, since the blank member 62 can diffuse the light of the LED 50 emitted in a place where the design translucent member 61 does not exist, for example, a pattern such as a flower formed by the light emission pattern of the LED 50 can be placed on the blank member 62. You can create effects such as placing multiple lights and making them glow vaguely.

Also, for example, the blank member 62 may be formed of a transparent light guide plate. With such a form, the LED 50 at the position corresponding to the blank member 62 can be visually recognized. Therefore, the design represented by the design translucent member 61 can be rendered such that the LEDs 50 cannot be visually recognized, and the light emission pattern of the LEDs 50 corresponding to the blank member 62 can be rendered visually visible in dots. By utilizing such a difference in presentation method, it is possible to exhibit an advertising effect that attracts more attention.

Also, for example, a plurality of receivers 4 may be provided and the plurality of receivers 4 may be connected to one transmitter 3 . With such a form, one luminous pattern can be displayed on a plurality of luminous sheets 5 . Therefore, for example, only one transmitter 3 can be provided inside the store for a plurality of light-emitting sheets 5 and design display members 6 provided outside the store, improving convenience.

7A is a vertical cross-sectional left side view of the second embodiment of the design display member 6 and the light-emitting sheet 5, and FIG. 7B is a vertical cross-sectional left side view of the third embodiment of the design display member 6 and the light-emitting sheet 5, 7C is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fourth embodiment, and FIG. 7D is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fifth embodiment.

For example, the shape of the designable translucent member 61 can be formed so as to swell in the outer peripheral direction from a portion embedded in the blank member 62 . In this case, the designable translucent member 61 has an embedded portion 611 embedded in the blank member 62 and a design portion 615 exposed on the front side.

The embedded portion 611 has a shape corresponding to the blank member hole 63 (the same width as the hole and the same height as the hole height) and is fitted into the blank member hole 63 . Specifically, the embedded portion 611 has the same width as the width of all or part of the blank member hole 63 and has a height equal to or less than the height of the blank member hole 63 . The embedded portion 611 is embedded in at least a portion of the blank member hole 63 . Therefore, the designable translucent member 61 is fixed to the blank member 62 by the embedding portion 611 .

The design portion 615 is formed continuously from the embedding portion 611, is formed to be wider than the width of the embedding portion 611, and has a design end portion 612 which is the end portion of the design shape having the widest width in the outer peripheral direction. . At this time, the length of the design portion 615 in the width direction becomes the design portion width 614 that is the width of the design portion 615 . The design portion width 614 is longer (thicker) than the embedding portion width 613, which is the width of the embedding portion 611, so as to expand to both sides in the width direction. Therefore, when the designed shape (designed portion 615 ) of the designable translucent member 61 is viewed from the front side, the boundary line between the embedded portion 611 and the blank member 62 is not visually recognized due to the designed portion 615 . In this case, the shape from the embedded portion 611 to the design end portion 612 hides the boundary line between the embedded portion 611 and the blank member 62 when viewed from the front side (the boundary line between the embedded portion 611 and the blank member 62 is hidden). is not visible). For example, the cross section in the front depth direction of the design shape of the designable translucent member 61 may be spherical with a diameter larger than the width of the embedding portion 611 (see FIG. 7A). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the portion from the embedding portion 611 to the design end portion 612 may be linearly inclined (see FIG. 7B). Alternatively, for example, the cross section in the front depth direction of the design shape of the designable translucent member 61 may be a semicircular shape whose diameter is larger than the width of the embedding portion 611 (see FIG. 7C). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the embedding portion 611 and the design end portion 612 may be continuously and linearly inclined (see FIG. 7D).

FIG. 8 is a perspective photographic image view of the design display member 6 and the luminescent sheet 5 in another form.
By making the design portion 615 wider than the embedded portion 611 in this way, when the design translucent member 61 is viewed from the front side as shown in FIG. The design shape (characters, figures, or patterns) of the member 61 can be visually recognized as if it were standing out, and the designability can be improved.

Further, a magnetic screw may be provided in the exterior 7 at a position where the vicinity of the end portion of the light emitting sheet 5 overlaps. Specifically, screws fixed in the depth direction can be provided at positions corresponding to the magnets arranged on the light-emitting sheet 5 of the exterior 7 so as to overlap. With such a configuration, it is possible to easily adjust the position and inclination of the light-emitting sheet 5 in the depth direction. Specifically, by tightening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged further in the depth direction. Alternatively, by loosening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged in the front direction. In addition, a plurality of light-emitting sheets 5 can be reliably arranged on the same plane. Therefore, it is possible to provide the designable light-emitting device 1 that emits light more uniformly without causing a difference in light distance (unevenness in the amount of light) due to a shift in the depth direction.

INDUSTRIAL APPLICABILITY This invention can be used to manufacture and sell designable light-emitting devices that are installed and used as advertisements.

As shown in FIG. 3 , in the design of “B” where the designable translucent member 61 is arranged and “three semicircles with different diameters”, the emitting LED 50 cannot be visually recognized, but the designable translucent member In the design of "O" in which 61 is not arranged, the emitting LED 50 can be visually recognized.
The designable translucent member 61 is not limited to the configuration described above, and may be a milky white acrylic material having a thickness of 5 mm and a transmittance (total light transmittance) of 42.3%. It can be made of a transparent material. The designable translucent member 61 can have a thickness of 3 mm to 15 mm, preferably 4 mm to 12 mm, and more preferably 5 mm to 10 mm. Further, the transmittance of the designable translucent member 61 can be 10% to 90%, preferably 20% to 80%, and more preferably 30% to 70%. In addition, the transmittance of the designable light-transmitting member 61 can vary within a suitable range depending on the thickness of the designable light-transmitting member 61. If the thickness of the designable light-transmitting member 61 is 3 mm or more and less than 8 mm, The degree of total light transmittance can be in the range of 10 to 60%, preferably in the range of 20 to 55%, more preferably in the range of 30 to 50%. Further, for example, if the thickness of the designable translucent member 61 is 8 mm or more and less than 15 mm, the transmittance can be in the range of 40 to 90% in total light transmittance, and is in the range of 50 to 80%. is preferred, and the range of 60 to 75% is more preferred.

The blank member 62 is a thin plate made of opaque plastic. Therefore, the light-emitting sheet 5 cannot be seen through the blank member 62 from the front side. The blank member 62 is a single plastic plate cut out in a linear shape with a constant thickness (width) and designed to represent "B", "O", and "three semicircles with different diameters". Blank member holes 63 representing three types of designs are provided, and design translucent members 61 are fitted into the respective blank member holes 63 . That is, the blank member 62 constitutes most or all of the design display member 6 other than the design translucent member 61 . Although the blank member 62 is opaque in this embodiment, it is not limited to being opaque as long as it has a different degree of transmittance (transparency) from that of the designable translucent member 61 . For example, the blank member 62 may have a higher transmittance (transparency) than the translucent design member 61 .

FIG. 5 is a cross-sectional view of the design display member 6 and the light-emitting sheet 5 in FIG. 1 taken along line AA.
The design display member 6 is arranged such that a part of the design translucent member 61 overlaps the sheet joint 56 when the two light-emitting sheets 5A and 5B are overlapped. In other words, the designable light-transmitting member 61 is arranged on the side of the two light-emitting sheets 5A and 5B on which the LEDs 50 emit light so as to straddle and cover the sheet joint 56 of the two light-emitting sheets 5A and 5B. The thickness in the height direction (horizontal direction in the drawing), which is the direction of light transmission, of the designable translucent member 61 is configured to be greater than the thickness in the height direction (horizontal direction in the drawing) of the blank member 62 . The translucent member 61 has a rear surface (left side surface in the drawing) that is flush with the rear surface of the blank member 62, and a peripheral surface (upper and lower surfaces in the drawing) of the blank member hole 63 of the blank member 62 (shown in the drawing). upper and lower surfaces) without gaps.

FIG. 6 is an enlarged front view of the designable light-emitting device 1 in FIG. 1 taken along line BB and CC.
When the two light-emitting sheets 5A and 5B are placed on top of the design display member 6, the LEDs 50 are arranged vertically within the range of the design translucent member 61 represented by a line having a thickness (width). They are arranged so that a plurality of them are included in one left and right direction.

Here, the operation when the designable light-emitting device 1 is actually used as a sign advertisement will be described.
The moving image reproducing device 2 stores moving image data to be reproduced in advance. Note that the moving image reproducing device 2 may be configured to acquire moving image data from the outside in real time and transmit the data to the transmitter 3 . The moving image reproduction device 2 transmits moving image data to the transmitter 3 . The moving image data is a moving image corresponding to the design (characters, figures, or patterns) of the design translucent member 61 . This moving image is, for example, a moving image in which the letter "B" gradually appears from the upper left, or a moving image in which "three semicircles with different diameters" gradually appear from each end. A video (or a still image) in which figures such as "three semicircles" appear, or figures such as "B", "O", and "three semicircles with different diameters" are bright and other parts are dark. can. In this embodiment, moving image data is used, but the image reproduced by the moving image reproducing device 2 is not limited to this. ) can be used.

The transmitter 3 receives the moving image data transmitted from the moving image reproducing device 2 and converts the received moving image data into light emission pattern data of the LEDs 50 by the moving image data conversion function. The transmitter 3 transmits light emission pattern data to the receiver 4 .

The receiver 4 receives the light emission pattern data transmitted from the transmitter 3, and divides the received light emission pattern data so as to correspond to the two light emission sheets 5A and 5B by the light emission pattern data division function. In this embodiment, the moving image data displayed in the square display area is divided so that the upper half is displayed on the luminous sheet 5A and the lower half is displayed on the luminous sheet 5B. The receiver 4 outputs the divided light emission pattern data to the light emission sheets 5A and 5B, and controls the light emission colors and light emission patterns of all the LEDs 50 . Therefore, the receiver 4 functions as a control device for the luminescent sheet 5 . In this embodiment, the receiver 4 is used as the control device, but the transmitter 3 or the video playback device 2 may be used as the control device.

All the LEDs 50 of the luminous sheet 5 are controlled by the receiver 4 . Then, the LED 50 emits light in the front direction so as to correspond to the light emission pattern data. The light (light rays) emitted by the light emission is diffused inside the design translucent member 61 and is transmitted in the front direction. At this time, the design of the design translucent member 61, which shines evenly and evenly, is clearly visible from the front side (the side where the light-emitting surface can be visually recognized). That is, the receiver 4 executes design emphasizing light emission for controlling light emission of the LEDs 50 so as to emphasize the design of the designable translucent member 61 with a light emission pattern corresponding to the position of the designable translucent member 61 and the design shape. do. In this design emphasizing light emission, only the portions having a design, such as the portion corresponding to the position of the design translucent member 61 and the shape of the design, and the portion performing the effect corresponding to the position of the blank member 62, emit light. The light emission pattern is controlled so that the light does not emit light.

With the above configuration, it is possible to provide a designable light-emitting device that emits light while emphasizing a linear shape representing a character, figure, or pattern, and that has a small number of parts that must be individually produced as a one-off product. .
The designable light-emitting device 1 includes a light-emitting sheet 5 having a plurality of LEDs 50 (light-emitting elements) arranged on its surface, and a designable light-transmitting device formed of a light diffusing material formed in a linear shape representing characters, figures, or patterns. A member 61 and a blank member 62 arranged in an area other than the design translucent member 61 are provided, and the receiver 4 emits design emphasizing light emission by causing the LEDs 50 to emit light so as to correspond to the position of the design translucent member 61. It is a configuration to control. With this configuration, linear shapes representing characters, graphics, or patterns can be made to stand out and emit light. Further, since the LED 50 at the position corresponding to the designable translucent member 61 is not directly visible, the designable translucent member 61 does not look like dots, and the light is diffused within the designable translucent member 61. Since the designable light-transmitting member 61 uniformly emits light, the design of the designable light-transmitting member 61 can be clearly recognized. In addition, compared to the conventional box letters that must be produced according to individual orders even for the housing, since there are fewer parts that must be individually produced as a one-off product, the designable light emitting device 1 can be inexpensive. .

Further, the blank member 62 is formed of a material whose transmittance (transparency) for transmitting light is different from the transmittance (transparency) of the design translucent member 61 . With this configuration, the boundary line between the designable translucent member 61 and the blank member 62 becomes clear, and the design of the designable translucent member 61 can be recognized more clearly. Specifically, by making the blank member 62 an opaque material, only the design translucent member 61 can emit light, and the design can be clearly recognized.

Further, the receiver 4 controls the light emission of the LED 50 by light emission pattern data converted from moving image data. With this configuration, the color and brightness of light emitted from the LEDs 50 can be changed in various ways, and an effect in which the design translucent member 61 changes in various colors and brightness can be realized.

In addition, the receiver 4 controls the light emission of all the LEDs 50 of the plurality of light-emitting sheets 5, and at least part of the designable translucent member 61 (including the designable translucent member 61) is composed of the two light-emitting sheets 5A. , 5B so as to straddle the sheet seam 56 . With this configuration, no matter how large the size of the designable light-transmitting member 61 is, there is no need to prepare one huge light-emitting sheet 5, and a plurality of light-emitting sheets 5 can be arranged side by side. can be done. That is, the designable light-emitting device 1 can be installed in various places, and can be suitably used as an outdoor advertisement.

Since the designable translucent member 61 exists on the sheet joint 56, the light from the LED 50 is diffused within the designable translucent member 61, and the upper portion of the sheet joint 56 is not darkened and is uniform. It can emit light. In particular, the distance between the edge LEDs 50 and the edge 57 of the light-emitting sheet is half the distance between the adjacent LEDs 50, so that the distance between the LEDs 50 in the portion straddling the sheet seam 56 is the same as the distance between the LEDs 50 in other portions. becomes. As a result, the design translucent member 61 at the sheet seam 56 does not become slightly dark or slightly bright, and can emit light uniformly.

In addition, in the light-emitting sheet 5, the edge spacing 55, which is the spacing between the LEDs 50 arranged at the extreme ends in the horizontal and vertical directions and the edge of the light-emitting sheet 5, is 40 to 60% of the light-emitting element spacing 53. have With this configuration, the designable light-transmitting member 61 does not form a shadow due to the sheet seam 56 even at the position overlapping the sheet seam 56, and the designable light-transmitting member 61 can emit light uniformly.

Further, the design translucent member 61 is milky white and has a thickness in the range of 5 mm to 12 mm and a transmittance (total light transmittance) in the range of 30 to 80%. With this configuration, the design of the designable light-transmitting member 61 can be clearly seen from a distance, and the designable light-transmitting member 61 has transparency to the extent that the LED 50 at the position corresponding to the designable light-transmitting member 61 cannot be visually recognized. can.

Further, among the plurality of LEDs 50 provided on the light-emitting sheets 5A and 5B, the LEDs 50 provided at positions facing the rear surface of the design translucent member 61 are caused to emit light, and the other LEDs 50 are not caused to emit light. Only the translucent member 61 emits light clearly and brightly to make the sign stand out, and the design translucent member 61 can be made bright and conspicuous by not causing the LEDs 50 in other portions to emit light. In addition, the LEDs 50 at positions not facing the rear surface of the designable translucent member 61 do not emit light, so that light leaks out from appropriate gaps, etc., and the light-emitting sheets 5A and 5B and the designable translucent member 61 provide effects and visual recognition. Clear visibility can be obtained without disturbing the line shapes representing the desired characters, figures, or patterns. In addition, since the LEDs 50 at positions not facing the rear surface of the translucent design member 61 do not emit light, it is possible to prevent unnecessary power from being used.

In addition, since the back surface of the light emitting sheet 5 is a rubber magnet or a magnetic material is arranged so that the magnetic force is applied to the back surface of the light emitting sheet 5, it can be used by being attracted not only to a flat surface but also to a curved surface or a spherical surface. can be done.

It should be noted that the present invention is not limited to the configurations of the above-described embodiments, and many embodiments can be obtained.
For example, the blank member 62 may be made of a translucent material having a lower transmittance (transparency) than the design translucent member 61 instead of an opaque material. With such a form, the boundary line between the designable translucent member 61 and the blank member 62 can be visually recognized as dimly shining, and the design can be changed. In this case, for example, the LED 50 that emits light in the shape of the designable translucent member 61 emits light so that the brightness gradually decreases toward the edge of the designable translucent member 61 toward the outside. The area around 61 can be dimly illuminated. Further, by setting the light emission pattern of the LEDs 50 at positions corresponding to the blank member 62 , it is possible to perform an effect that gives an impression different from the light emission pattern of the design translucent member 61 . Specifically, since the blank member 62 can diffuse the light of the LED 50 emitted in a place where the design translucent member 61 does not exist, for example, a pattern such as a flower formed by the light emission pattern of the LED 50 can be placed on the blank member 62. You can create effects such as placing multiple lights and making them glow vaguely.

Also, for example, the blank member 62 may be formed of a transparent light guide plate. With such a form, the LED 50 at the position corresponding to the blank member 62 can be visually recognized. Therefore, the design represented by the design translucent member 61 can be rendered such that the LEDs 50 cannot be visually recognized, and the light emission pattern of the LEDs 50 corresponding to the blank member 62 can be rendered visually visible in dots. By utilizing such a difference in presentation method, it is possible to exhibit an advertising effect that attracts more attention.

Also, for example, a plurality of receivers 4 may be provided and the plurality of receivers 4 may be connected to one transmitter 3 . With such a form, one luminous pattern can be displayed on a plurality of luminous sheets 5 . Therefore, for example, only one transmitter 3 can be provided inside the store for a plurality of light-emitting sheets 5 and design display members 6 provided outside the store, improving convenience.

7A is a vertical cross-sectional left side view of the second embodiment of the design display member 6 and the light-emitting sheet 5, and FIG. 7B is a vertical cross-sectional left side view of the third embodiment of the design display member 6 and the light-emitting sheet 5, 7C is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fourth embodiment, and FIG. 7D is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fifth embodiment.

For example, the shape of the designable translucent member 61 can be formed so as to swell in the outer peripheral direction from a portion embedded in the blank member 62 . In this case, the designable translucent member 61 has an embedded portion 611 embedded in the blank member 62 and a design portion 615 exposed on the front side.

The embedded portion 611 has a shape corresponding to the blank member hole 63 (the same width as the hole and the same height as the hole height) and is fitted into the blank member hole 63 . Specifically, the embedded portion 611 has the same width as the width of all or part of the blank member hole 63 and has a height equal to or less than the height of the blank member hole 63 . The embedded portion 611 is embedded in at least a portion of the blank member hole 63 . Therefore, the designable translucent member 61 is fixed to the blank member 62 by the embedding portion 611 .

The design portion 615 is formed continuously from the embedding portion 611, is formed to be wider than the width of the embedding portion 611, and has a design end portion 612 which is the end portion of the design shape having the widest width in the outer peripheral direction. . At this time, the length of the design portion 615 in the width direction becomes the design portion width 614 that is the width of the design portion 615 . The design portion width 614 is longer (thicker) than the embedding portion width 613, which is the width of the embedding portion 611, so as to expand to both sides in the width direction. Therefore, when the designed shape (designed portion 615 ) of the designable translucent member 61 is viewed from the front side, the boundary line between the embedded portion 611 and the blank member 62 is not visually recognized due to the designed portion 615 . In this case, the shape from the embedded portion 611 to the design end portion 612 hides the boundary line between the embedded portion 611 and the blank member 62 when viewed from the front side (the boundary line between the embedded portion 611 and the blank member 62 is hidden). is not visible). For example, the cross section in the front depth direction of the design shape of the designable translucent member 61 may be spherical with a diameter larger than the width of the embedding portion 611 (see FIG. 7A). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the portion from the embedding portion 611 to the design end portion 612 may be linearly inclined (see FIG. 7B). Alternatively, for example, the cross section in the front depth direction of the designed shape of the designable translucent member 61 may be a semicircular shape whose diameter is larger than the width of the embedding portion 611 (see FIG. 7C). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the embedding portion 611 and the design end portion 612 may be continuously and linearly inclined (see FIG. 7D).

FIG. 8 is a perspective photographic image view of the design display member 6 and the luminescent sheet 5 in another form.
By making the design portion 615 wider than the embedded portion 611 in this way, when the design translucent member 61 is viewed from the front side as shown in FIG. The design shape (characters, figures, or patterns) of the member 61 can be visually recognized as if it were standing out, and the designability can be improved.

Further, a magnetic screw may be provided in the exterior 7 at a position where the vicinity of the end portion of the light emitting sheet 5 overlaps. Specifically, screws fixed in the depth direction can be provided at positions corresponding to the magnets arranged on the light-emitting sheet 5 of the exterior 7 so as to overlap. With such a configuration, it is possible to easily adjust the position and inclination of the light-emitting sheet 5 in the depth direction. Specifically, by tightening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged further in the depth direction. Alternatively, by loosening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged in the front direction. In addition, a plurality of light-emitting sheets 5 can be reliably arranged on the same plane. Therefore, it is possible to provide the designable light-emitting device 1 that emits light more uniformly without causing a difference in light distance (unevenness in the amount of light) due to a shift in the depth direction.

INDUSTRIAL APPLICABILITY This invention can be used to manufacture and sell designable light-emitting devices that are installed and used as advertisements.

Utility Model Registration No. 3176260

However, box letters, such as the internally illuminated pseudo-metal casing described above, use multiple LEDs and require wiring to power the LEDs. For this reason, the arrangement and wiring of the LEDs and the shape of the casing differ depending on the shape of the box letter to be produced. In addition, as the size of the box character to be produced increases, the number of necessary LEDs increases, and accordingly the wiring also increases.

Further, the light-emitting sheet 5 is provided with a magnetic layer (not shown) on the back surface. This magnetic layer is a layer of a rubber magnet provided over the entire back surface. Although a magnetic layer is provided in this embodiment, the light-emitting sheet 5 only needs to have a magnet arranged in a part thereof so as to apply a magnetic force to a position on the back surface corresponding to the position of the outer packaging 7 . For example, thin magnets may be arranged on the rear surface corresponding to the position of the exterior 7 . The light-emitting sheet 5 has all the LEDs 50 electrically connected on a flexible substrate (not shown), and is connected to the receiver 4 with a signal cable (not shown) so that all the LEDs 50 can be controlled.

Note that the two light-emitting sheets 5A and 5B may be entirely curved in the thickness direction instead of being flat, or may be curved in a wave shape in the thickness direction. However, the two light-emitting sheets 5A and 5B are arranged on the same plane with each other regardless of the form.

Also, the base sheet 51 may have a circular shape. Furthermore, the base sheet 51 may be provided with other means for fixing with the sheath 7, such as screw holes, without the rubber magnets. In this case, the exterior 7 side also has screw holes at positions corresponding to the positions of the screw holes on the base sheet 51 side, and the base sheet 51 (light emitting sheet 5) and the exterior 7 are screwed. Instead of the magnetic layer, male and female hook-and-loop fasteners may be provided on the back surface of the base sheet 51 and the surface of the exterior 7 so as to face each other.

When the translucent designable member 61 is milky white, the thickness is such that it receives light emitted from the light-emitting sheet 5 arranged on the back side (emission of light), diffuses the light inside, and transmits the light to the front side. and transmittance, which are such a thickness and transmittance that LEDs 50 (described later) constituting the light-emitting sheet 5 cannot be visually recognized when viewed from the front side when the light from the light-emitting sheet 5 is transmitted. As shown in FIG. 3 , in the design of “B” where the designable translucent member 61 is arranged and “three semicircles with different diameters”, the emitting LED 50 cannot be visually recognized, but the designable translucent member In the design of "O" in which 61 is not arranged, the emitting LED 50 can be visually recognized.

The blank member 62 is a thin plate made of opaque plastic. Therefore, the light-emitting sheet 5 cannot be seen through the blank member 62 from the front side. The blank member 62 is a single plastic plate cut out in a linear shape with a constant thickness (width) and designed to represent "B", "O", and "three semicircles with different diameters". Blank member holes 63 representing three types of designs are provided, and design translucent members 61 are fitted into the respective blank member holes 63 . That is, the blank member 62 constitutes most or all of the design display member 6 other than the design translucent member 61 . Although the blank member 62 is opaque in this embodiment, it is not limited to being opaque as long as it has a different degree of transmittance (transparency) from that of the designable translucent member 61 . For example, the blank member 62 may have a higher transmittance (transparency) than the translucent design member 61 .

FIG. 5 is a cross-sectional view of the design display member 6 and the light-emitting sheet 5 in FIG. 1 taken along line AA.
The design display member 6 is arranged such that a part of the design translucent member 61 overlaps the sheet joint 56 when the two light-emitting sheets 5A and 5B are overlapped. In other words, the designable light-transmitting member 61 is arranged on the side of the two light-emitting sheets 5A and 5B on which the LEDs 50 emit light so as to straddle and cover the sheet joint 56 of the two light-emitting sheets 5A and 5B. The thickness in the height direction (horizontal direction in the drawing), which is the direction of light transmission, of the designable translucent member 61 is configured to be greater than the thickness in the height direction (horizontal direction in the drawing) of the blank member 62 .

FIG. 6 is an enlarged front view of the designable light-emitting device 1 in FIG. 1 taken along line BB and CC.
When the two light-emitting sheets 5A and 5B are placed on top of the design display member 6, the LEDs 50 are arranged vertically within the range of the design translucent member 61 represented by a line having a thickness (width). They are arranged so that a plurality of them are included in one left and right direction.

Here, the operation when the designable light-emitting device 1 is actually used as a sign advertisement will be described.
The moving image reproducing device 2 stores moving image data to be reproduced in advance. Note that the moving image reproducing device 2 may be configured to acquire moving image data from the outside in real time and transmit the data to the transmitter 3 . The moving image reproduction device 2 transmits moving image data to the transmitter 3 . The moving image data is a moving image corresponding to the design (characters, figures, or patterns) of the design translucent member 61 . This moving image is, for example, a moving image in which the letter "B" gradually appears from the upper left, or a moving image in which "three semicircles with different diameters" gradually appear from each end. A video (or a still image) in which figures such as "three semicircles" appear, or figures such as "B", "O", and "three semicircles with different diameters" are bright and other parts are dark. can. In this embodiment, moving image data is used, but the image reproduced by the moving image reproducing device 2 is not limited to this. ) can be used.

The transmitter 3 receives the moving image data transmitted from the moving image reproducing device 2 and converts the received moving image data into light emission pattern data of the LEDs 50 by the moving image data conversion function. The transmitter 3 transmits light emission pattern data to the receiver 4 .

The receiver 4 receives the light emission pattern data transmitted from the transmitter 3, and divides the received light emission pattern data so as to correspond to the two light emission sheets 5A and 5B by the light emission pattern data division function. In this embodiment, the moving image data displayed in the square display area is divided so that the upper half is displayed on the luminous sheet 5A and the lower half is displayed on the luminous sheet 5B. The receiver 4 outputs the divided light emission pattern data to the light emission sheets 5A and 5B, and controls the light emission colors and light emission patterns of all the LEDs 50 . Therefore, the receiver 4 functions as a control device for the luminescent sheet 5 . In this embodiment, the receiver 4 is used as the control device, but the transmitter 3 or the video playback device 2 may be used as the control device.

All the LEDs 50 of the luminous sheet 5 are controlled by the receiver 4 . Then, the LED 50 emits light in the front direction so as to correspond to the light emission pattern data. The light (light rays) emitted by the light emission is diffused inside the design translucent member 61 and is transmitted in the front direction. At this time, the design of the design translucent member 61, which shines evenly and evenly, is clearly visible from the front side (the side where the light-emitting surface can be visually recognized). That is, the receiver 4 executes design emphasizing light emission for controlling light emission of the LEDs 50 so as to emphasize the design of the designable translucent member 61 with a light emission pattern corresponding to the position of the designable translucent member 61 and the design shape. do. In this design emphasizing light emission, only the portions having a design, such as the portion corresponding to the position of the design translucent member 61 and the shape of the design, and the portion performing the effect corresponding to the position of the blank member 62, emit light. The light emission pattern is controlled so that the light does not emit light.

With the above configuration, it is possible to provide a designable light-emitting device that emits light while emphasizing a linear shape representing a character, figure, or pattern, and that has a small number of parts that must be individually produced as a one-off product. .
The designable light-emitting device 1 includes a light-emitting sheet 5 having a plurality of LEDs 50 (light-emitting elements) arranged on its surface, and a designable light-transmitting device formed of a light diffusing material formed in a linear shape representing characters, figures, or patterns. A member 61 and a blank member 62 arranged in an area other than the design translucent member 61 are provided, and the receiver 4 emits design emphasizing light emission by causing the LEDs 50 to emit light so as to correspond to the position of the design translucent member 61. It is a configuration to control. With this configuration, linear shapes representing characters, graphics, or patterns can be made to stand out and emit light. Further, since the LED 50 at the position corresponding to the designable translucent member 61 is not directly visible, the designable translucent member 61 does not look like dots, and the light is diffused within the designable translucent member 61. Since the designable light-transmitting member 61 uniformly emits light, the design of the designable light-transmitting member 61 can be clearly recognized. In addition, compared to the conventional box letters that must be produced according to individual orders even for the housing, since there are fewer parts that must be individually produced as a one-off product, the designable light emitting device 1 can be inexpensive. .

Further, the blank member 62 is formed of a material whose transmittance (transparency) for transmitting light is different from the transmittance (transparency) of the design translucent member 61 . With this configuration, the boundary line between the designable translucent member 61 and the blank member 62 becomes clear, and the design of the designable translucent member 61 can be recognized more clearly. Specifically, by making the blank member 62 an opaque material, only the design translucent member 61 can emit light, and the design can be clearly recognized.

Further, the receiver 4 controls the light emission of the LED 50 by light emission pattern data converted from moving image data. With this configuration, the color and brightness of light emitted from the LEDs 50 can be changed in various ways, and an effect in which the design translucent member 61 changes in various colors and brightness can be realized.

In addition, the receiver 4 controls the light emission of all the LEDs 50 of the plurality of light-emitting sheets 5, and at least part of the designable translucent member 61 (including the designable translucent member 61) is composed of the two light-emitting sheets 5A. , 5B so as to straddle the sheet seam 56 . With this configuration, no matter how large the size of the designable light-transmitting member 61 is, there is no need to prepare one huge light-emitting sheet 5, and a plurality of light-emitting sheets 5 can be arranged side by side. can be done. That is, the designable light-emitting device 1 can be installed in various places, and can be suitably used as an outdoor advertisement.

Since the designable translucent member 61 exists on the sheet joint 56, the light from the LED 50 is diffused within the designable translucent member 61, and the upper portion of the sheet joint 56 is not darkened and is uniform. It can emit light. In particular, the distance between the edge LEDs 50 and the edge 57 of the light-emitting sheet is half the distance between the adjacent LEDs 50, so that the distance between the LEDs 50 in the portion straddling the sheet seam 56 is the same as the distance between the LEDs 50 in other portions. becomes. As a result, the design translucent member 61 at the sheet seam 56 does not become slightly dark or slightly bright, and can emit light uniformly.

In addition, in the light-emitting sheet 5, the edge spacing 55, which is the spacing between the LEDs 50 arranged at the extreme ends in the horizontal and vertical directions and the edge of the light-emitting sheet 5, is 40 to 60% of the light-emitting element spacing 53. have With this configuration, the designable light-transmitting member 61 does not form a shadow due to the sheet seam 56 even at the position overlapping the sheet seam 56, and the designable light-transmitting member 61 can emit light uniformly.

Further, the design translucent member 61 is milky white and has a thickness in the range of 5 mm to 12 mm and a transmittance (total light transmittance) in the range of 30 to 80%. With this configuration, the design of the designable light-transmitting member 61 can be clearly seen from a distance, and the designable light-transmitting member 61 has transparency to the extent that the LED 50 at the position corresponding to the designable light-transmitting member 61 cannot be visually recognized. can.

Further, among the plurality of LEDs 50 provided on the light-emitting sheets 5A and 5B, the LEDs 50 provided at positions facing the rear surface of the design translucent member 61 are caused to emit light, and the other LEDs 50 are not caused to emit light. Only the translucent member 61 emits light clearly and brightly to make the sign stand out, and the design translucent member 61 can be made bright and conspicuous by not causing the LEDs 50 in other portions to emit light. In addition, the LEDs 50 at positions not facing the rear surface of the designable translucent member 61 do not emit light, so that light leaks out from appropriate gaps, etc., and the light-emitting sheets 5A and 5B and the designable translucent member 61 provide effects and visual recognition. Clear visibility can be obtained without disturbing the line shapes representing the desired characters, figures, or patterns. In addition, since the LEDs 50 at positions not facing the rear surface of the translucent design member 61 do not emit light, it is possible to prevent unnecessary power from being used.

In addition, since the back surface of the light emitting sheet 5 is a rubber magnet or a magnetic material is arranged so that the magnetic force is applied to the back surface of the light emitting sheet 5, it can be used by being attracted not only to a flat surface but also to a curved surface or a spherical surface. can be done.

It should be noted that the present invention is not limited to the configurations of the above-described embodiments, and many embodiments can be obtained.
For example, the blank member 62 may be made of a translucent material having a lower transmittance (transparency) than the design translucent member 61 instead of an opaque material. With such a form, the boundary line between the designable translucent member 61 and the blank member 62 can be visually recognized as dimly shining, and the design can be changed. In this case, for example, the LED 50 that emits light in the shape of the designable translucent member 61 emits light so that the brightness gradually decreases toward the edge of the designable translucent member 61 toward the outside. The area around 61 can be dimly illuminated. Further, by setting the light emission pattern of the LEDs 50 at positions corresponding to the blank member 62 , it is possible to perform an effect that gives an impression different from the light emission pattern of the design translucent member 61 . Specifically, since the blank member 62 can diffuse the light of the LED 50 emitted in a place where the design translucent member 61 does not exist, for example, a pattern such as a flower formed by the light emission pattern of the LED 50 can be placed on the blank member 62. You can create effects such as placing multiple lights and making them glow vaguely.

Also, for example, the blank member 62 may be formed of a transparent light guide plate. With such a form, the LED 50 at the position corresponding to the blank member 62 can be visually recognized. Therefore, the design represented by the design translucent member 61 can be rendered such that the LEDs 50 cannot be visually recognized, and the light emission pattern of the LEDs 50 corresponding to the blank member 62 can be rendered visually visible in dots. By utilizing such a difference in presentation method, it is possible to exhibit an advertising effect that attracts more attention.

Also, for example, a plurality of receivers 4 may be provided and the plurality of receivers 4 may be connected to one transmitter 3 . With such a form, one luminous pattern can be displayed on a plurality of luminous sheets 5 . Therefore, for example, only one transmitter 3 can be provided inside the store for a plurality of light-emitting sheets 5 and design display members 6 provided outside the store, improving convenience.

7A is a vertical cross-sectional left side view of the second embodiment of the design display member 6 and the light-emitting sheet 5, and FIG. 7B is a vertical cross-sectional left side view of the third embodiment of the design display member 6 and the light-emitting sheet 5, 7C is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fourth embodiment, and FIG. 7D is a vertical left side view of the design display member 6 and the light emitting sheet 5 in the fifth embodiment.

For example, the shape of the designable translucent member 61 can be formed so as to swell in the outer peripheral direction from a portion embedded in the blank member 62 . In this case, the designable translucent member 61 has an embedded portion 611 embedded in the blank member 62 and a design portion 615 exposed on the front side.

The embedded portion 611 has a shape corresponding to the blank member hole 63 (the same width as the hole and the same height as the hole height) and is fitted into the blank member hole 63 . Specifically, the embedded portion 611 has the same width as the width of all or part of the blank member hole 63 and has a height equal to or less than the height of the blank member hole 63 . The embedded portion 611 is embedded in at least a portion of the blank member hole 63 . Therefore, the designable translucent member 61 is fixed to the blank member 62 by the embedding portion 611 .

The design portion 615 is formed continuously from the embedding portion 611, is formed to be wider than the width of the embedding portion 611, and has a design end portion 612 which is the end portion of the design shape having the widest width in the outer peripheral direction. . At this time, the length of the design portion 615 in the width direction becomes the design portion width 614 that is the width of the design portion 615 . The design portion width 614 is longer (thicker) than the embedding portion width 613, which is the width of the embedding portion 611, so as to expand to both sides in the width direction. Therefore, when the designed shape (designed portion 615 ) of the designable translucent member 61 is viewed from the front side, the boundary line between the embedded portion 611 and the blank member 62 is not visually recognized due to the designed portion 615 . In this case, the shape from the embedded portion 611 to the design end portion 612 hides the boundary line between the embedded portion 611 and the blank member 62 when viewed from the front side (the boundary line between the embedded portion 611 and the blank member 62 is hidden). is not visible). For example, the cross section in the front depth direction of the design shape of the designable translucent member 61 may be spherical with a diameter larger than the width of the embedding portion 611 (see FIG. 7A). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the portion from the embedding portion 611 to the design end portion 612 may be linearly inclined (see FIG. 7B). Alternatively, for example, the cross section in the front depth direction of the design shape of the designable translucent member 61 may be a semicircular shape whose diameter is larger than the width of the embedding portion 611 (see FIG. 7C). Alternatively, for example, in the front depth direction cross-section of the design shape of the designable translucent member 61, the embedding portion 611 and the design end portion 612 may be continuously and linearly inclined (see FIG. 7D).

FIG. 8 is a perspective photographic image view of the design display member 6 and the luminescent sheet 5 in another form.
By making the design portion 615 wider than the embedded portion 611 in this way, when the design translucent member 61 is viewed from the front side as shown in FIG. The design shape (characters, figures, or patterns) of the member 61 can be visually recognized as if it were standing out, and the designability can be improved.

Further, a magnetic screw may be provided in the exterior 7 at a position where the vicinity of the end portion of the light emitting sheet 5 overlaps. Specifically, screws fixed in the depth direction can be provided at positions corresponding to the magnets arranged on the light-emitting sheet 5 of the exterior 7 so as to overlap. With such a configuration, it is possible to easily adjust the position and inclination of the light-emitting sheet 5 in the depth direction. Specifically, by tightening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged further in the depth direction. Alternatively, by loosening a screw (adjustment screw) provided on the exterior, the position of the light emitting sheet 5 can be arranged in the front direction. In addition, a plurality of light-emitting sheets 5 can be reliably arranged on the same plane. Therefore, it is possible to provide the designable light-emitting device 1 that emits light more uniformly without causing a difference in light distance (unevenness in the amount of light) due to a shift in the depth direction.

INDUSTRIAL APPLICABILITY This invention can be used to manufacture and sell designable light-emitting devices that are installed and used as advertisements.
