[First Embodiment]
A light-emitting device (light-emitting accessory) 1 according to the first embodiment of the present invention includes a light-emitting unit 3 and a first member (first container) 5, as shown in FIG. ing.

  The light-emitting unit 3 includes at least one light-emitting body (for example, two LEDs 7 (7A and 7B) that emit light (visible light)). Then, in the light emitting section 3, a light emitting portion (a light emitting LED 7; a position with respect to the first member 5) changes with time.

  The first member 5 is formed of a transparent body or a translucent body (for example, a half mirror) in a tubular or cup shape. The light emitting section 3 is provided inside the first member 5.

  Further, the first member 5 transmits a part of the light emitted from the light emitting unit 3 and reflects another part.

  The light emitting section 3 is composed of, for example, two LEDs 7A and 7B provided on the upper surface of the base body 9. Inside the base body 9 (below the LED 7), a power supply (not shown) and a control board (not shown) for controlling the light emission pattern of the LEDs 7A and 7B are provided. Then, for example, the two LEDs 7A and 7B blink alternately.

  More specifically, the first member 5 is formed in a cup shape with a conical side surface. That is, the developed view of the first member 5 has a fan shape as shown in FIG.

  The fan shape shown in FIG. 2 is formed in a sheet shape having a thickness in a direction orthogonal to the paper surface of FIG. Further, the fan-shaped one shown in FIG. 2 reflects part of light and transmits part of light on both sides in the thickness direction of the sheet.

  Note that the surface of the first member 5 is not necessarily required to be subjected to reflection processing, and when light emitted from the light emitting unit 3 is applied to the first member 5, a part of the light The other part of the light may be reflected by the surface of the first member 5 and transmitted through the first member 5.

  When the first member 5 is formed of a material such as a synthetic resin or glass, a special reflection such as coating is applied to the surface of the first member 5 (for example, both sides in the thickness direction of the fan-shaped member shown in FIG. 2). Unless the prevention processing is performed, the first member 5 reflects a part of the light and transmits a part of the light.

  When the first member 5 is formed of a half mirror, the light transmittance and the reflectance are substantially equal to each other.

  In the above description, a conical side shape is listed as one example of the cup shape, but the shape is not limited to this shape.

  By the way, the cup shape means one solid (for example, a larger solid) of two solids obtained when a shell-shaped solid is divided into two at a predetermined one place (for example, one predetermined plane). It is the shape of.

  The shell-shaped solid is formed of the above-mentioned film when the entire surface of a solid having a predetermined shape (for example, a solid solid having a predetermined shape in which a through hole is not formed) is covered with a film having a certain thickness, for example. It is a three-dimensional shape. The shape of the film (shell-shaped solid) does not include the solid of the predetermined shape, so that a space having the same shape as the solid of the predetermined shape is formed inside. In addition, the thickness of the film may not be constant and may be appropriately changed depending on a part.

  In the cup shape (cup-shaped solid), one surface in the thickness direction of the film (the outer surface of the cup-shaped solid) is convex as a whole, and the other surface in the thickness direction of the film (cup-shaped). The inner surface of the solid is concave as a whole.

  The first member 5 is desirably formed in a cup shape and a rotating body shape. The conical side surface shape is an example of a cup shape and a rotating body shape.

  Here, the rotator refers to a central axis composed of one straight line drawn on one plane, and when the predetermined one line is rotated 360 ° around the central axis, the predetermined one line is drawn. It is a solid represented by the locus of a book line. Since the cup-shaped first member 5 is actually thick, it is assumed that the predetermined one line has a slight width.

  The predetermined one line has one end in the extending direction on the central axis, and extends to a side away from the central axis on one side of the one plane with the central axis as a boundary. I have. The other end of the predetermined line in the extending direction is apart from the central axis.

  In the cup-shaped rotating body, the predetermined one line is formed by at least one of a straight line and a curved line. However, when the predetermined one line is constituted only by a line segment orthogonal to the central axis, the trajectory does not have a cup shape.

  In addition, the predetermined one line does not intersect itself. Further, unless the predetermined one line is composed of only a line segment orthogonal to the central axis, the extending direction of the central axis is the extending direction of the predetermined one line. The position of one end and the position of the other end are different from each other.

  The first member 5 is integrally installed on an upper surface of a base body 9 formed, for example, in a short column shape. As a result, the circular opening (a portion corresponding to the bottom surface of the cone) of the first member 5 having a conical side surface is closed by the base member 9, and the first member 5 and the base member 9 define the circular opening. The LEDs 7A and 7B are housed in the enclosed conical space.

  The light-emitting unit 3 includes a plurality of LEDs 7 (7A to 7L), for example, as shown in FIG. 3, and each of the LEDs 7 (7A to 7L) of the light-emitting unit 3 independently (each other). They may be turned on (in a different manner) and turned off (flashing). Then, each of the LEDs 7 (7A to 7L) may be configured to turn on and turn off in order, so that the light emitting portion of the light emitting unit 3 changes with time.

  The mode shown in FIG. 3 will be further described. As the LEDs 7 (7G to 7L), those having a beam angle of, for example, a wide angle (for example, 80 ° to 120 °) are employed. The light-emitting unit 3 includes a first group of LEDs 7A to 7F and a second group of LEDs 7G to 7L.

  The first group of LEDs 7A to 7F are arranged at positions where the circumference of a circle (virtual circle) 11 having a first diameter on the upper surface of the base body 9 is equally distributed. The second group of LEDs 7G to 7L are arranged at positions where the circumference of a circle (virtual circle) 13 of the second diameter on the upper surface of the base body 9 is equally distributed. The circle 11 having the first diameter and the circle 13 having the second diameter are on the same plane, and the centers C1 of the circles 11 and 13 coincide with each other. The center C1 of each of the circles 11 and 13 exists on the center axis of the first member 5.

  Further, each of the first group of LEDs 7A to 7F and each of the second group of LEDs 7G to 7L are arranged alternately. That is, the angle α1 formed by the LED 7A, the center C1 of each of the circles 11, 13 and the LED 7G is equal to the angle α2 formed by the LED 7G, the center C1 of each of the circles 11 and 13, and the LED 7B.

  Each of the first group of LEDs 7A to 7F is sequentially turned on and off (blinks) in a predetermined rotation direction (clockwise direction in FIG. 3). Each of the second group of LEDs 7G to 7L is sequentially turned on and off (blinks) in a direction opposite to the rotation direction of the first group of LEDs 7A to 7F (counterclockwise in FIG. 3). . Each of the first group of LEDs 7A to 7F and each of the second group of LEDs 7G to 7L may be sequentially turned on and off in the same direction.

  More specifically, each of the first group of LEDs 7A to 7F is repeatedly turned on and off. In addition, the light-off time is longer than the light-on time.

  Then, from a state where all of the LEDs 7A to 7F of the first group are turned off, the first LED 7A is turned on and turned off, and then the second LED which is one LED adjacent to the first LED 7A is turned on. LED 7B is turned on and turned off, and then a third LED 7C, which is one LED adjacent to the second LED 7B (an LED opposite to the first LED 7A), is turned on and turned off, Subsequently, the operation of turning on and off the sixth LED 7F adjacent to the first LED 7A, and then turning on and off the first LED 7A is repeated. That is, the operation of turning on and off the LEDs 7A to 7F sequentially along the circumference of the circle 11 having the first diameter is performed over a plurality of circumferences of the circle.

  In the above description, in the first group of LEDs 7A to 7F, two or more LEDs 7 do not light up at the same time. However, the first group of LEDs 7A to 7F may be configured so that the plurality of LEDs 7 may light up at the same time. For example, even if the second LED 7B is turned on while the first LED 7A is turned on, the first LED 7A is turned off while the second LED 7B is turned on. Good. Further, each of the LEDs 7 may be configured to blink at random instead of blinking sequentially along the circumference of the virtual circles 11 and 13.

  The second group of LEDs 7G to 7L are also turned on similarly to the first group of LEDs 7A to 7F. Here, the first group of LEDs 7A to 7F and the second group of LEDs 7G to 7L may be turned on in synchronization with each other. For example, the LED 7A and the LED 7G may be turned on and off at the same time, then the LED 7B and the LED 7H may be turned on and off at the same time, and similarly, the operation of turning on and off the following LEDs may be repeated. . Also, for example, the LED 7A is turned on and then turned off, then the LED 7G is turned on at the same time, the LED 7G is turned on and then turned off, and the LED 7B is turned on at the same time. It may be.

  Note that the intervals between the LEDs 7 do not necessarily have to be constant. Further, a configuration in which a plurality of LEDs 7 are randomly arranged on the upper surface of the base body 9 may be employed.

  According to the light emitting device 1, the first member 5 is formed in a transparent or translucent body in a tubular or cup shape, and the light emitting unit 3 is provided inside the first member 5. Is reflected by the first member 5, passes through the first member 5, and further repeats reflection and transmission, so that the light emitted by the light emitting section 3 reaches the human eye. Thereby, the decorativeness is higher than before.

  In particular, by arranging the LEDs 7 as shown in FIG. 3 and emitting light in the above-described manner, the first member 5 moves the point-like light source along the double helix, so that the decorativeness is high. Become.

[Second embodiment]
The light emitting device 1A according to the second embodiment of the present invention differs from the light emitting device 1 according to the first embodiment in having an object 15 as shown in FIG. It is configured almost similarly to the light emitting device 1.

  The object 15 of the light emitting device 1A according to the second embodiment is formed of a solid body of a predetermined shape in a transparent or translucent body.

  The object 15 is separate from the first member 5 and transmits a part of the light emitted by the light emitting unit 3 and reflects the other part. 17 and a columnar portion 19. Note that, similarly to the first member 5, the surface of the object 15 does not necessarily need to be subjected to reflection processing.

  As shown in FIG. 4A, the star-shaped portion 17 is formed in a solid shape surrounded by twenty triangular planes that are congruent with each other. More specifically, in FIG. 4A, ten triangular planes that are congruent with each other are formed on one side in the thickness direction of the star-shaped portion 17. Similarly, ten triangular planes that are congruent with each other are formed on the other side in the thickness direction of the star-shaped portion 17 (see FIG. 4B). The columnar portion 19 protrudes from one of the five concave portions of the star-shaped portion 17.

  The first member 5 shown in FIG. 4 is formed in a tubular shape by being formed in a truncated cone side surface shape. That is, a small conical side top is removed from the first member 5 shown in FIGS. 1 and 2.

  In the present application, the shape of the tube changes not only in the shape of a cylinder or a square tube whose cross-sectional shape by a plane perpendicular to the center axis of the tube is always constant, but also in the extending direction of the center axis of the tube. I will include what I do.

  More specifically, the term “cylindrical” in the present application means that a single straight line has a central axis drawn on one plane, and a single line segment of a predetermined length separated from the central axis on the one plane (necessarily (It is not necessary to be parallel to the central axis) or a single curve is drawn, and when this drawn line segment or curve is rotated 360 ° around the central axis, the rotating body represented by the locus of the straight line or the curve Shape. The line segments and the curves do not cross each other, nor do they cross the central axis.

  In the light emitting device 1 </ b> A, a part of the object 15 enters the inside of the first member 5, and the other part of the object 15 is positioned outside the first member 5, so that the object 15 is attached to the first member 5. is set up.

  More specifically, the columnar portion 19 of the object 15 enters the inside of the first member 5 through the circular opening at the upper end of the first member 5, and the star-shaped portion 17 is located at the upper end of the first member 5. The object 15 is placed on the upper end of the first member 5 so as to be hooked on the small circular opening.

  Part of the light emitted by the light emitting section 3 enters the object 15 from, for example, the lower surface of the cylindrical portion 19, and the incident light is emitted from the star-shaped portion 17 of the object 15 to the outside of the light emitting device 1A. ing.

  As shown in FIG. 5, the first member 5 may be formed in a cup shape (for example, a conical side shape), and all the objects 15 may be provided inside the first member 5.

  In this case, a part of the light emitted from the light emitting unit 3 is incident on the object 15, and the incident light is emitted from the object 15 and irradiated on the first member 5.

  Further, when the object 15 is provided inside the first member 5, the first member 5 may be formed in a frustoconical side surface shape, and although the object 15 is solid, A cavity may be provided inside 15.

  According to the light emitting device 1A, the object 15 has a transparent or translucent object 15, and the light emitted from the light emitting unit 3 is transmitted not only through the first member 5 but also through the object 15 and reflected by the object 15. Is done. Thereby, the decorativeness is further enhanced.

  In the light emitting devices 1 and 1A, the first member 5 may be formed in a regular polygonal pyramid side surface shape as shown in FIG. FIG. 7 is a development view of the first member 5 shown in FIG. 6, and a plurality of radial line segments 21 shown in FIGS. 6 and 7 are bending lines. The portion of the isosceles triangle between the fold lines 21 is a flat surface in the first member 5 having a side surface shape of a regular polygonal pyramid.

[Third Embodiment]
The light emitting device 1B according to the third embodiment of the present invention has a point that a second member 23 similar to the first member 5 is provided so as to overlap the first member 5, as shown in FIG. However, unlike the light-emitting device 1 according to the first embodiment and the light-emitting device 1A according to the second embodiment, the other points are substantially the same as those of the light-emitting devices 1 and 1A.

  The second member (second container) 23 of the light emitting device 1 </ b> B is formed of a transparent or translucent body (for example, a half mirror) in a tubular or cup shape, and overlaps the first member 5. I have. The second member 23 is formed, for example, in substantially the same shape as the first member 5.

  More specifically, in the light emitting device 1B shown in FIG. 8A, the first member 5 is formed in a regular polygonal pyramid side surface shape, and the second member 23 is formed in a conical side surface shape. Then, the second member 23 overlaps the first member 5 so that the first member 5 fits inside the second member 23. Thereby, as shown in FIG. 9A, the ridge line 25 of the first member 5 is in line contact with the inner peripheral surface of the second member 23. In addition, a gap 27 having a slight size is formed between the first member 5 and the second member 23 in a portion other than the portion in line contact.

  In the light emitting device 1B shown in FIG. 8B, the first member 5 is formed in a conical side surface, and the second member 23 is formed in a regular polygonal pyramid side shape. Then, the second member 23 overlaps the first member 5 so that the first member 5 fits inside the second member 23. Thereby, as shown in FIG. 9B, the bus 29 of the first member 5 is in line contact with the planar inner peripheral surface of the second member 23. In addition, a gap 27 having a slight size is formed between the first member 5 and the second member 23 in a portion other than the portion in line contact.

  In the light emitting device 1B shown in FIGS. 8A and 8B, the second member 23 is outside the first member 5 (the first member 5 enters the inside of the second member 23). ) Overlaps the first member 5, and a part of the outer surface of the first member 5 contacts a part of the inner surface of the second member 23 in at least one of line contact and point contact. This is an example of a light emitting device in which a gap 27 is formed between another portion of the outer surface of the first member 5 and another portion of the inner surface of the second member 23.

  According to the light emitting device 1B, since the second member 23 overlaps the first member 5, the light emitted by the light emitting unit 3 is reflected and transmitted by the first member 5 and the second member 23. Repeatedly, the decorativeness further increases.

  According to the light emitting device 1B, a part of the outer surface of the first member 5 is in contact with a part of the inner surface of the second member 23 in at least one of line contact and point contact. Convergence and diffusion of the light emitted from the light emitting section 3 occur at and around this contact point, and the difference in light intensity between these parts at the first member 5 and the second member 23 is reduced. The first member 5 and the second member 23 appear to emit light in a complicated form.

  By the way, in the light emitting device 1B shown in FIG. 8, the second member 23 is in contact with the first member 5 and the second member 23 is overlapped with the first member 5. The first member 5 and the second member 23 may be separated from each other as shown in FIG. In the light emitting device 1C shown in FIG. 10, for example, the second member 23 is separated from the first member 5 by using a support member (not shown), and the first member 5 and the second member 23 are mutually separated. The second member 23 is in a non-contact state, and a lower half to a quarter of the first member 5 is exposed from the second member 23.

  In the above description, the members are doubled because the second member 23 is superimposed on the first member 5. However, not two but three or more plural members are superposed. It may be a configuration. In this case, the configuration shown in FIG. 8 and the configuration shown in FIG. 10 may be mixed.

  In the above description, the light emitting unit 3 is configured using the plurality of LEDs 7 that do not move (the positions are fixed) with respect to the first member 5 and the second member 23, but are illustrated in FIG. As described above, the LED 7 of the light emitting unit 3 may be relatively moved with respect to the first member 5 and the second member 23.

  The light emitting device 1D shown in FIG. 11 has the LED 7 (7A, 7B) installed on the LED installation body 31. By rotating the LED installation body 31 with an actuator such as a motor 33, the LED 7 is turned into the first member 5 or the like. It is moving with respect to the second member 23. In this case, the LED 7 may remain lit or blink.

  Further, in the above description, the first member 5 and the second member 23 have a conical side surface shape, a truncated conical side shape, and a regular polygonal pyramid side shape, but as shown in FIG. The first member 5 and the second member 23 may have a cylindrical shape, a cylindrical shape with a bottom (cylindrical square shape), or as shown in FIG. The second member 23 may be in the shape of a square tube or a bottomed square tube (a rectangular parallelepiped square), or as shown in FIG. 12 (c), the first member 5 or the second member 23. May have a pyramidal side surface shape (for example, a quadrangular pyramid side shape). That is, the first member 5 and the second member 23 only have to be cylindrical or square.
