Description

[Technical field]

[0001] The present invention relates to a light-emitting fan, and more particularly to a light-emitting fan used as a cheering fan at events such as concerts. [Background technology]

[0002] FIG. 12 is a front view of the fan shown in Patent Document 1, FIG. 13 is a rear view of the fan shown in Patent Document 1, and FIG. 14 is a side view of the fan shown in Patent Document 1.

[0003] Referring to these figures, fan 121 is composed of a fan portion 122 formed in a flat plate shape, a gripping portion 123 extending from the side of fan portion 122, an LED tape light 124 attached to the outer periphery of fan portion 122, an LED for illumination 125 attached to gripping portion 123, and a control portion 126 attached to gripping portion 123 and connected to LED tape light 124 and LED for illumination 125 via wiring 130a, 130b.

[0004] The fan section 122 includes a framework 127 and plastic flat plates 128a, 128b attached to both sides of the framework 127.

[0005] The control unit 126 is formed with a button 129. The button 129 is a switch for the LED light strip 124, and pressing the button 129 turns on or off the light source of the LED light strip 124.

[0006] When in use, characters such as the name of the performer being supported are written on the surface of the fan section 122, and the LED tape light 124 and the lighting LED 125 are turned on. The light emitted from the LED tape light 124 is directed outward from the fan section 122 and illuminates the outer periphery of the fan section 122. This makes the outer periphery of the fan section 122 brighter due to the light emitted from the LED tape light 124. Also, the light emitted from the lighting LED 125 is directed toward the surface of the fan section 122 and illuminates the surface of the fan section 122. This improves the visibility of the characters written on the fan section 122 due to the light emitted from the lighting LED 125.

[0007] However, the fan disclosed in Patent Document 1 as described above only emits spotlights at the light source, and therefore cannot emit uniform light over the entire surface of fan section 122, resulting in low light emission efficiency.

[0008] Thus, conventionally, there exists a fan that includes a fan section made of a light-transmitting material, a handle connected to the fan section, and a light source arranged so that light is incident on the side of the fan section from one direction (Patent Documents 2 and 3). In the fan of Patent Document 2, light emitted from the light source attached to the handle is incident on the side of the fan section. In the fan of Patent Document 3, light emitted from a light source attached in a straight line near the handle is incident on the side of the fan section. Therefore, the light incident from the light source can cause the fan section to emit surface light. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2021-20032 A [Patent Document 2] JP 2001-223 A [Patent Document 3] JP 2016-165460 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, in the fans shown in Patent Documents 2 and 3 described above, the illuminance of the light incident from the light source decreases as it travels through the fan section, which can result in unevenness in the way the light is emitted between areas near the light source and those farther away from the light source, and there is a risk that the entire fan section will not emit light evenly.

[0037] Figure 1 is a schematic oblique view of a luminous fan according to the first embodiment of the present invention, Figure 2 is a front view of the luminous fan shown in Figure 1, Figure 3 is a back view of the luminous fan shown in Figure 1, Figure 4 is an enlarged end view of line IV-IV shown in Figure 2, Figure 5 is a schematic oblique view of the luminous fan shown in Figure 1 when disassembled, and Figure 6 is a photograph of the luminous fan assembled with a diffusion sheet and a shading sheet attached.

[0038] With reference to these figures, the light-emitting fan 1 is used as a fan for cheering at events such as concerts, and is mainly composed of a light-emitting fan body 2 and a grip part 3 connected to the fan body 2. In the present invention, light-emitting refers to a state in which the fan appears to be glowing when viewed from the outside.

[0039] The fan body 2 is composed of a fan section 11 made of a translucent material formed into a flat plate, a holding section 12 that holds the sides and back of the fan section 11, a plurality of light sources 13 arranged to emit light around the entire side of the fan section 11, a reflective sheet 14 arranged on the back side of the fan section 11, and a frame 15 that holds the entire outer periphery of the front of the fan section 11.

[0040] The sector part 11 is made of a light-transmitting acrylic plate and has a substantially circular shape. The thickness of the sector part 11 (the length from the front to the back of the sector part 11 in the left-right direction in FIG. 4) is 5 mm.

[0041] The holding portion 12 is made of a non-translucent material, has a substantially circular shape, and includes a base portion 21 that covers the entire back surface of the sector portion 11, and a raised portion 22 that is connected to the outer edge of the base portion 21 and covers the entire side surface of the sector portion 11.

[0042] The light sources 13 are composed of a plurality of LEDs 24. The LEDs 24 are installed on one side of a tape-shaped substrate 23. The other side of the substrate 23 is attached to the inner surface of the rising portion. That is, the light sources 13 are lighting devices that emit light only from one side, and are installed at a position between the rising portion 22 and the side of the fan portion 11, with the light-emitting surface facing the side of the fan portion 11. By configuring in this way, the light sources 13 and the side of the fan portion 11 are in close proximity to each other, improving the light-emitting efficiency of the fan portion 11. The light sources 13 are connected to a power cable (not shown) and a signal cable (not shown), and are connected to a power source stored in the grip portion 3 described later through the power cable. They are also connected to a control unit 32 stored in the grip portion 3 described later through the signal cable.

[0043] The reflective sheet 14 has a substantially circular shape with the same outer edge shape as the sector portion 11 , and is disposed between the base portion 21 of the holding portion 12 and the rear surface of the sector portion 11 .

[0044] Referring to Fig. 6, the fan body 2 further includes a diffusion sheet 16 and a shading sheet 17. The diffusion sheet 16 has a substantially circular shape with the same outer edge as the fan section 11, and is arranged on the front side of the fan section 11. The shading sheet 17 has a substantially circular shape with the same outer edge as the fan section 11, and is arranged on the front side of the diffusion sheet 16. The shading sheet 17 has portions cut out in the shape of letters or figures. With this configuration, the cut-out portions of the shading sheet shine, making it possible to convey visual information such as letters or figures.

[0045] 1 and 4, the frame 15 is composed of a frame-shaped first portion 25 having an outer edge shape similar to that of the holding portion 12, a step 27 that drops from the inner edge end of the first portion 25 toward the sector portion 11, and a second portion 26 that extends from the sector portion 11 side end of the step 27 toward the center. When the frame 15 is attached to the holding portion 12, the first portion 25 engages with the rising portion 22 with its outer edge end in contact with the outer surface of the rising portion 22. The second portion 26 extends inward from the entire outer edge of the sector portion 11 so as to cover the outer edge end on the front side of the sector portion 11.

[0046] The grip portion 3 has a cylindrical shape and is formed with a color change button 31 for changing the luminous color of the light source 13. Inside the grip portion 3, there are a control unit 32 that controls the light source 3 so that the luminous color of the light source 3 changes every time the color change button 31 is pressed, and a battery box 33 in which a battery is installed. This battery functions as a power source that drives the light source 13 and the control unit 32. With this configuration, the luminous color changes when the color change button 31 is pressed, making it possible to switch the luminous color.

[0047] 5, during assembly, first, the reflective sheet 14 (not shown) is placed on the inner surface of the base portion 21. Next, the base portion 21 is moved in the direction indicated by the dashed-dotted arrow A1 to align it with the fan portion 11. Then, the frame body to which the diffusion sheet and shielding sheet (not shown) are attached is moved in the direction indicated by the dashed-dotted arrow A2 to align the fan portion 11 with the frame body 15. Finally, the frame body 15 is engaged with the rising portion 22. As a result, the outer peripheral edge of the fan portion 11 is fixed by the holding portion 12 and the frame body 15, so that the attachment state of the fan portion 11 is stable.

[0048] Next, a state in which the light emitted from the light source is surface-emitted will be described.

[0049] FIG. 7 is a schematic end view showing the state of light diffusion of the light-emitting fan shown in FIG. 1, and FIG. 8 is an enlarged view of the X portion shown in FIG.

[0050] 4 and 7, the light emitted from the light source 13 enters the side of the fan section 11 and travels straight through the fan section 11 (up and down in FIG. 7) or travels toward the back side (left side in FIG. 7) and the front side (right side in FIG. 7). The light traveling toward the back side tries to leak out from the back side, but because the reflective sheet 14 is arranged, the light hits the reflective sheet 14 and is reflected, and travels inside the fan section 11 toward the front side. The light traveling toward the front side in the fan section 11 is emitted to the outside from the front side. Note that not all of the light traveling toward the front side is necessarily emitted to the outside, but a part of the light hits a diffusion sheet or a light-shielding sheet and is reflected, and travels inside the fan section 11 toward the back side. In this way, the light emitted from the light source 13 travels while repeatedly reflecting inside the fan section 11, and is emitted to the outside from the front side. As a result, the fan section 11 shines toward the front side of the light-emitting fan 1.

[0051] In a conventional light-emitting fan, the light emitted from light source 13 and incident on the side surface becomes less illuminant as it travels through fan section 11. When light from light source 13 enters from only one direction, the area near the point of incidence is bright, and the further away from light source 13 it is, the more difficult it is for the light to reach. Therefore, at positions farther from light source 13, the brightness of the light directed toward the front side of fan section 11 is insufficient, resulting in uneven brightness.

[0052] As described above, in the light-emitting fan 1 of the present invention, multiple light sources 13 are arranged at predetermined intervals along the entire circumference of the side surface of the fan section 11. With this configuration, light can be made incident on the side surface of the fan section 11 from all directions. Therefore, even if the illuminance of light incident from one direction becomes low, light can be incident from other directions and travels while repeatedly reflecting within the fan section 11, making it difficult for areas to be reached by light to occur. Furthermore, as the light incident on the side surface from all directions travels while repeatedly reflecting within the fan section 11, the entire fan section 11 can be made to shine more uniformly.

[0053] In addition, the sides and back of the fan section 11 are covered by the holding section 12 (base section 21 and rising section 22) made of a non-translucent material. This configuration makes it difficult for light to leak to the outside from the sides and back of the fan section 11. Therefore, when there are many spectators around at an event venue such as a concert, the fan section 11 can shine toward the performers in front, rather than shining in the direction of the spectators.

[0054] Furthermore, the light-shielding sheet has cutouts that correspond to the shapes of characters or figures, so that the cutouts light up when in the light-emitting state, making it possible to convey visual information such as characters or figures to performers in front.

[0055] 8, as described above, thickness T1 of sector section 11 is 5 mm. Sector section 11 is disposed so that light emitted from light source 13 passes through at least center 34 in the thickness T1 direction of the side surface. With this configuration, light from light source 13 can be taken in toward center 34 of sector section 11, improving the luminous efficiency of sector section 11.

[0056] The thickness of the fan section may be made thinner than the length of the light source in the front-to-back direction. In that case, the structure shown in Figures 9 and 10 will result. Note that the front-to-back direction refers to the direction connecting the front and back of the fan section when the fan is held upright. Light is then emitted over the entire range of the light source's length in the front-to-back direction.

[0057] FIG. 9 is a schematic perspective view of the light-emitting Japanese paper fan according to the second embodiment of the present invention, corresponding to FIG. 5 of the first embodiment, and FIG. 10 is an enlarged view of the light-emitting Japanese paper fan shown in FIG. 9, corresponding to FIG. 8 of the first embodiment.

[0058] Note that the light-emitting Japanese paper fan according to this second embodiment has the same basic configuration as the light-emitting Japanese paper fan according to the first embodiment shown in FIG. 1. Here, the description will focus on the differences.

[0059] Referring to FIGS. 9 and 10, the light-emitting Japanese paper fan 51 further includes cylindrical support portions 52a to 52f that rise from the base portion 71 in the vicinity of the inner side surface of the rising portion 72. The side surfaces of the support portions 52a to 52f are formed in a tapered shape.

[0060] The thickness T2 of the fan portion 61 is thinner than the length L in the front-rear direction (the left-right direction in FIG. 10) of the light source 63 (T2 < L). More specifically, the thickness T2 of the fan portion 61 is 3 mm, which is 40% of the thickness with respect to the light source 13. In the assembled state, since the side surface of the fan portion 61 and the side surfaces of the support portions 52a to 52f are in contact with each other, a gap is generated between the base portion 71 and the back surface of the fan portion 61. That is, the fan portion 61 is fixed in a state separated from the base portion 71 and the reflection sheet 62 by the support portions 52a to 52f. And the fan portion 61 is arranged such that the light irradiated from the light source 63 passes through at least the center 74 in the thickness T2 direction of the side surface of the fan portion 61. Thus, even when the thickness T2 of the fan portion 61 is thin, the support portions 52a to 52f can adjust the position to capture the light of the fan portion 61.

[0061] Also, the support portion may be a straight circular cylinder. In that case, the structure shown in FIG. 11 is obtained. FIG. 11 is an enlarged view of the light-emitting Japanese paper fan according to the third embodiment of the present invention, corresponding to FIG. 8 of the first embodiment.

[0062] Still, the glow paper lantern according to this third embodiment has the same basic configuration as the glow paper lantern according to the second embodiment shown in FIG. 9. Here, the description will focus on the differences.

[0063] Referring to FIG. 11, in the glow paper lantern 81, the support portion is formed in a straight circular column shape. Also, the thickness T3 of the fan portion 91 is 3 mm, which is 40% of the thickness with respect to the light source 83. That is, the thickness T3 of the fan portion 91 is thinner than the length L in the front-rear direction (left-right direction in FIG. 11) of the light source 83 (T3 < L). In the assembled state of the glow paper lantern 81, the side surface of the fan portion 91 and the side surface of the support portion are in contact, and the back surface of the fan portion 91 and the reflective sheet 92 are in contact and fixed. And the fan portion 91 is arranged so that the light irradiated from the light source 83 passes through at least the center 104 in the thickness T3 direction of the side surface of the fan portion 91. By configuring in this way, since light can be taken into the center 104 of the fan portion 91, the light emission efficiency of the fan portion 91 is improved.

[0064] Still, in each of the above embodiments, a plate made of transparent acrylic resin is used for the fan portion, but for example, a transparent resin such as polycarbonate may be used, and as long as the inside is transparent for efficient transmission of the incident light, a plate of other materials may be used.

[0065] Also, in each of the above embodiments, the cross-sectional shape of the fan portion is a specific shape, but other shapes may be used. For example, random uneven shapes or dot grooves at a predetermined interval may be formed on the front surface side or the back surface side. As a result, the light incident on the fan portion is refracted and reflected repeatedly in the uneven shapes and dot grooves, so that the light diffusion effect can be improved.

[0066] Furthermore, in each of the above embodiments, the fan portion is formed in a substantially circular shape, but in addition to these, it may be formed in other shapes such as a perfect circle shape, a star shape, a heart shape, a rectangular shape, etc.

[0067] Furthermore, in each of the above embodiments, the fan section has a specific thickness, but it may be 2mm to 5mm, and is preferably 40% to 70% of the length of the light source in the front-to-rear direction. By configuring it in this way, light can be taken in to the center of the fan section, improving the light-emitting efficiency of the fan section. Also, by reducing the thickness of the fan section, the weight of the entire fan can be reduced, improving usability.

[0068] Furthermore, in each of the above embodiments, the fan portion has a specific and constant thickness, but it may have another thickness, or may have a thickness that varies depending on the location, such as a tapered shape.

[0069] Furthermore, in each of the above embodiments, the holding portion includes a base portion and a rising portion, but the base portion may be omitted.

[0070] Furthermore, in each of the above embodiments, the light source is specified as an LED, but it may be something else that emits light, such as an incandescent light bulb.

[0071] Furthermore, in each of the above-described embodiments, the plurality of light sources are attached to the inner surface of the rising portion, but they may be attached to the sector side.

[0072] Furthermore, in each of the above embodiments, the multiple light sources are provided in a tape shape, but other configurations are also possible as long as they are arranged so as to emit light toward the side surface of the fan portion.

[0073] Furthermore, in each of the above embodiments, the base portion is formed in a shape that covers the entire back surface of the fan portion, but it may have another shape as long as it can cover at least a portion of it.

[0074] Furthermore, in each of the above embodiments, the raised portion is seamlessly and integrally connected to the entire circumference of the base portion, but other connection modes are also possible as long as the raised portion is connected to at least a portion of the entire circumference of the base portion.

[0075] Furthermore, in each of the above-described embodiments, the rising portion is formed in a shape that covers the entire side surface of the sector portion, but it may have another shape as long as it can cover at least a portion of the side surface.

[0076] Furthermore, in each of the above embodiments, the reflective sheet has a specific shape, but it may have another shape.

[0077] Furthermore, in each of the above embodiments, a reflective sheet is disposed between the base portion of the holder and the sector portion, but the reflective sheet may be omitted. Also, not only the reflective sheet but also other sheets may be disposed between the holder and the sector portion, and multiple sheets may be disposed.

[0078] Furthermore, in each of the above embodiments, the holding portion is made of a non-light-transmitting material, but it may be made of a light-transmitting material.

[0079] Furthermore, in each of the above embodiments, the fan portion is held by the holding portion and the frame, but the frame may be omitted.

[0080] Furthermore, in each of the above embodiments, the frame holds the entire outer periphery of the front surface of the fan section, but other configurations are possible as long as they can hold at least a portion of the outer periphery. For example, the frame may be made up of a plurality of members that hold portions of the outer periphery of the fan section.

[0081] Furthermore, in each of the above embodiments, the light blocking sheet has a specific shape, but it may have another shape.

[0082] Furthermore, in each of the above embodiments, a light-shielding sheet is disposed in front of the fan section, but the light-shielding sheet may be omitted. Also, in addition to the light-shielding sheet, other sheets may be disposed in front of the fan section, or multiple sheets may be disposed. [Explanation of symbols]
