FIG. 11 is a cross-sectional view of a main part showing a modified example of the present invention.

Hereinafter, one embodiment of the luminous toy of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a light-emitting toy according to one embodiment of the present invention, in which (a) is a perspective view showing the exterior, and (b) is a perspective view showing the light-emitting toy with a lid portion open.

The light-emitting toy 1 shown in FIG. 1 is a container-type toy whose appearance is, for example, as shown in FIG. 1(a) and has a circular shape in plan view and a roughly elliptical shape in side view. The toy case includes a lower main body 2 and a lid 3 that is decorated on the outside and covers the main body 2.

As shown in FIG. 1B, the lid 3 is configured to be openable and closable with a hinge 4 provided on one end of the main body 2 as a fulcrum. The lid 3 is biased in the opening direction by, for example, a torsion spring (not shown) provided on the hinge 4, and a locking piece 5 provided on the opposite side of the hinge 4 engages with a locking hole 6 provided on the main body 2 to maintain the closed state. The main body 2 is also provided with an irradiated object 10 having a ring-shaped pattern 10a that resembles a ribbon (figure). The ring-shaped pattern 10a is a part that shines brightly when irradiated by the light of the light-emitting unit 8 (see FIG. 2) described later, and the irradiated object 10 itself is disk-shaped with a hole 10h (see FIG. 2) in the center, and a first member 11 and a second member 12 are provided on the inside (inside the pattern 10a) and outside (outside the pattern 10a) of the lid 3, as described later.

FIG. 2 is an exploded perspective view of the main body 2 shown in FIG.
2, the main body 2 is roughly composed of a main body case 2a, an irradiated body 10, a first member 11 and a second member 12 that overlap the irradiated body 10, a first reflector 21 attached to the back side of the irradiated body 10, a second reflector 22 arranged at a predetermined interval from the first reflector 21, and a light emitting unit 8 arranged facing the first reflector 21. In this embodiment, the reflector 20 that reflects light from the light emitting unit 8 is configured to include two reflectors (the first reflector 21 and the second reflector 22) as described above.

The irradiated object 10 has a hole 10h in the center for attaching the first reflector 21, and a flat mounting surface 10f of the first member 11 is provided between the hole 10h and the pattern portion 10a on the outer edge side. This irradiated object 10 is made of a light-transmitting material. The irradiated object 10 is preferably made of milk, and its light transmittance is preferably 30% to 70%. The first member 11 has a decorative portion 11a whose center portion is raised in a diamond cut shape, and the outer edge contour portion 11e corresponds to the inner peripheral edge 10ie of the pattern portion 10a. The first member 11 is also made of a material with lower light transmittance than the irradiated object 10.

The second member 12 has an annular structure with an opening 12h corresponding to the outer edge 10ue of the irradiated body 10, and a boss 12b is provided on the back side for fixing to the main body case 2a. The second member 12 is made of a material with lower light transmittance than the irradiated body 10. The light emitting unit 8 is made of light emitting elements 8a, 8b, and 8c, for example, three LEDs, provided on a circuit board 7. The main body case 2a has a circuit board 7 attached to it approximately in the center of its interior, and a driving unit 40 such as a power supply is provided adjacent to the circuit board 7. That is, the circuit board 7 and the driving unit 40 are arranged on the opposite side (back side) of the irradiated body 10 across the second reflector 22.

FIG. 3 is a cross-sectional view taken along line AA shown in FIG.
As shown in Fig. 3, the first reflector 21 is attached to the main body case 2a at the center of the circuit board 7 having the light emitting unit 8. The second reflector 22 is provided so that its opening 22h corresponds to the outer edge 7e of the circuit board 7. That is, the second reflector 22 is attached to the main body case 2a so that its central opening 22h surrounds the light emitting unit 8. The second reflector 22 has a second reflecting surface 22r that reflects light. The second reflecting surface 22r is configured as a concave curved surface except for the opening 22h. The second reflector 22 can be configured to reflect light by, for example, mirror-finishing the surface of the second reflecting surface 22r and coloring it in a white-based color.

A first reflector 21 is provided above the light-emitting unit 8. The first reflector 21 is fixed to the center back side of the irradiated body 10 via, for example, a mounting screw 60. This fixing is performed together with the first member 11 arranged on the front side with the irradiated body 10 in between. The first reflector 21 is configured with a convex curved surface that bulges toward the light-emitting unit 8. The outer diameter dimension (the dimension in the left-right direction in the figure) is configured to be larger than the dimension of the opening 22h of the second reflector 22. The configuration that allows the first reflector 21 to reflect light can be configured in the same way as the second reflecting surface 22r described above. In this way, the first reflector 21 and the second reflector 22 form a light-guiding space SP through which the light from the light-emitting unit 8 can pass.

As described above, the irradiated object 10 has the pattern portion 10a on the outer edge side, and this pattern portion 10a is configured to protrude toward the pattern portion surface (upper side in the figure) at an appropriate height H. The outer edge portion 10t of the irradiated object 10 is configured to protrude toward the opposite side (back side) from the pattern portion 10a, and the protruding tip is configured to contact the second reflecting surface 22r.
The first member 11 arranged inside the pattern portion 10a is configured to be thinner than the protruding height of the pattern portion 10a. Therefore, the pattern portion 10a is configured to protrude from the surface 11s of the first member 11 with a step d1. The pattern portion 10a is also configured to have a step d2 with respect to the surface 12s of the second member 12 arranged to contact the outer edge portion 10ue.

When the light-emitting unit 8 arranged in this manner emits light, the light illuminates the pattern unit 10a. At this time, the light (La, Lb, Lc) emitted from the light-emitting elements 8a, 8b, 8c is reflected, for example, by the first reflecting surface 21r, and the reflected light is reflected by the second reflecting surface 22r and guided to the flat illuminated surface 10b (back side) on the back side of the pattern unit 10a.

FIG. 4 is a plan view of the main body 2 showing the positional relationship between the light emitting section 8 and other members.
As shown in Fig. 4, the light-emitting unit 8 is provided with three light-emitting elements (light-emitting elements 8a, 8b, and 8c) as described above, and for example, the first light-emitting element 8a can be arranged as red (R), the second light-emitting element 8b as green (G), and the third light-emitting element 8c as blue (B). The light-emitting elements 8a, 8b, and 8c are arranged, for example, at approximately equal intervals around a center point Cp (see Figs. 2 and 5). As shown in Fig. 4, the first member 11 is arranged so as to overlap the light-emitting unit 8 in a plan view. The pattern portion 10a of the irradiated object 10 is located outside the first member 11.

The three light-emitting elements 8a, 8b, and 8c are arranged at a predetermined distance d3 between them so that the light emitted by each of the light-emitting elements 8a, 8b, and 8c illuminates a different position on the pattern portion 10a, and the distance between the light-emitting elements is approximately equal (approximately the vertices of an equilateral triangle). The three light-emitting elements 8a, 8b, and 8c are arranged, for example, to match the main points 10A, 10B, and 10C on the pattern portion 10a. In other words, each of the light-emitting elements 8a, 8b, and 8c is arranged between the center point Cp and each of the main points 10A, 10B, and 10C.

FIG. 5 is a schematic diagram showing how light from the multiple light emitting elements 8a, 8b, and 8c spreads in a plan view of the pattern portion 10a.
The light-emitting elements 8a, 8b, and 8c are arranged at a predetermined interval, so that when viewed in a plan view, the light-emitting elements 8a, 8b, and 8c form regions of the respective colors as shown in Fig. 5. For example, the first light-emitting element 8a forms a red region (R), the second light-emitting element 8b forms a green region (G), and the third light-emitting element 8c forms a blue region (B).

Here, the amount of light emitted from each of the light-emitting elements 8a, 8b, and 8c decreases as the light is tilted to the side from the direction directly above the light-emitting elements 8a, 8b, and 8c. The light reflected by the first reflecting surface 21r is reflected by the convex surface in a direction spreading out to the side and guided to the second reflecting surface 22r, and finally reaches the illuminated surface 10b. Considering such a light guide path and the arrangement of the light-emitting elements 8a, 8b, and 8c, the light-emitting elements 8a, 8b, and 8c are arranged in accordance with the main points 10A, 10B, and 10C, so that the main points 10A, 10B, and 10C shine in colors close to the primary colors of the respective colors.
The portion directly above the light-emitting portion 8 is provided with the first reflector 21 and the first member 11, so that the portion does not shine in accordance with the pattern portion 10a.

Meanwhile, the red area (R), green area (G), and blue area (B) each form a color-mixed area. In particular, when viewed in a circular range that matches the pattern portion 10a, a red-green area (R+G), a blue-green area (B+G), and a red-blue area (R+B) are formed. Note that in the illustration, each area is shown as being divided by an illustrated pattern (hatching), but in reality, colors are mixed together and the color changes gradually (hue (color tone) state). Furthermore, the changes that occur due to this color mixing are not only changes in hue, but also in the so-called color tone such as brightness (brightness) and saturation (color vividness), which gradually change depending on the distance from each light-emitting element 8a, 8b, 8c.

6A and 6B are plan views of the main body 2, in which (a) is a plan view showing a state before the light-emitting unit 8 emits light, and (b) is a plan view when the light-emitting unit 8 emits light.
As mentioned above, when the light-emitting section 8 is off, the pattern section 10a, together with the first member 11 and the second member 12, is not lit and is shown in its original color as shown in Fig. 6(a). However, when the light-emitting section 8 is turned on, the pattern section 10a shines brighter than the first member 11 inside it and the surrounding second member 12 as shown in Fig. 6(b). As for how the pattern section 10a shines, as mentioned above, the main points 10A, 10B, and 10C shine the brightest, and furthermore, the color is developed in a color close to each primary color (R, G, B).

In addition, in the parts of the pattern portion 10a that are farther away from the main points 10A, 10B, and 10C, the brightness decreases with distance and the color shines with a mixed color hue. In this way, the brightness and color of the annular pattern portion 10a change in three cycles in the circumferential direction. In addition, because the pattern portion 10a protrudes from the surfaces of the first member 11 and the second member 12, it shines as if it is floating when viewed from an oblique horizontal direction.

FIG. 7 is a cross-sectional view of a main part showing a modification of this embodiment.
The configuration shown in FIG. 7 differs from the configuration of the main body 2 shown in FIG. 3 in the arrangement of the light emitting portion 8 and the structure of the reflector 20, but otherwise has the same configuration as that described above.
As shown in Fig. 7, a circuit board 7 having a plurality of light-emitting elements 8a, 8b, and 8c is provided at the position where the first reflector 21 is provided in Fig. 3. Furthermore, in the figure, a first reflector 21 having a concave first reflecting surface 21r is disposed at approximately the same position as the second reflector 22 described above so as to face the light-emitting unit 8 provided on the lower side of the circuit board 7.

The reflector 20 shown in FIG. 7 has an overall concave shape, but is not necessarily limited to this shape. For example, the shape of the reflector 20 may be a structure in which the area facing the light-emitting unit 8 is flat, convex toward the light-emitting unit, or conical toward the light-emitting unit.

As described above, the light-emitting toy 1 of this embodiment illuminates the irradiated object 10 with the light of the light-emitting unit 8 reflected by the reflector 20, so the positional relationship between the light-emitting unit 8 and the irradiated object 10 can be adjusted by the reflector 20. In addition, the irradiated object 10 has optical transparency that allows the irradiated light to pass through, so the pattern portion 10a can be expressed by the transmitted light.

In the light-emitting toy 1 of this embodiment, the reflector 20 is provided between the light-emitting unit 8 and the pattern unit 10a of the irradiated object 10, and this reflector 20 makes it possible to freely control the position and orientation of the irradiated object 10 relative to the arrangement of the light-emitting unit 8. For example, the first reflector 21 is configured as a convex surface that bulges outward toward the light-emitting unit 8, so that the light of the light-emitting unit 8 can be guided in a direction that spreads outward from the center of the light-emitting unit 8.
Furthermore, since the second reflector 22 is configured as a concave surface capable of guiding light toward the irradiated body 10, it is possible to effectively illuminate the irradiated body 10. For example, the irradiated surface 10b of the irradiated body 10 of the light-emitting toy 1 of this embodiment is arranged in a ring shape away from the outside of the light-emitting unit 8 in a plan view, but since the reflector 20 has a curved surface that guides the reflected light of the light-emitting unit 8 toward the irradiated body 10, it is possible to effectively guide the light of the light-emitting unit 8 to the ring-shaped irradiated surface 10b.

In the light-emitting toy 1 of this embodiment, the pattern portion 10a of the irradiated object 10 is surrounded by a first member 11 and a second member 12 that have a lower light transmittance than the irradiated object 10, so that the brightness of the pattern portion 10a can be more effectively accentuated when the light-emitting portion 8 emits light. In addition, since the first member 11 is positioned so as to overlap the light-emitting portion 8 in a plan view, the internal structure including the light-emitting portion 8 cannot be seen through the irradiated object 10.

In addition, in the light-emitting toy 1 of this embodiment, the driving unit 40 of the light-emitting unit 8 is provided on the opposite side of the irradiated object 10 across the second reflector 22, so that the arrangement and shape of the irradiated object 10, and further the light-guiding space SP are not affected, and the pattern portion 10a of the irradiated object 10 can be easily arranged and made large in size.

In this embodiment of the light-emitting toy 1, the pattern portion 10a is arranged to protrude from the surfaces of the first member 11 and the second member 12, which do not substantially emit light, so that the pattern portion 10a can be presented in a three-dimensional shape when illuminated.

The light-emitting unit 8 in the light-emitting toy 1 of this embodiment includes a plurality of light-emitting elements 8a, 8b, and 8c that emit light of different colors, and thus can express various colors. In addition, the light-emitting elements 8a, 8b, and 8c are arranged at predetermined intervals so that the light emitted by each of the light-emitting elements 8a, 8b, and 8c illuminates different positions on the irradiated object 10, and thus, in addition to expressing a plurality of colors, a color gradation can be expressed.
In particular, in a configuration in which the light-emitting elements 8a, 8b, and 8c of the three primary colors of light are arranged so that the distance between the light-emitting elements 8a, 8b, and 8c is approximately equal (approximately an equilateral triangle), the color tones on the circumference of the circle of the three light-emitting elements 8a, 8b, and 8c can be presented with a rich variety of color changes at three equal intervals in a plan view. Furthermore, by arranging the three light-emitting elements 8a, 8b, and 8c in accordance with the main points 10A, 10B, and 10C of the pattern portion 10a, the main points 10A, 10B, and 10C of the pattern portion 10a can be emphasized as bright and vivid points close to each of the three primary colors, and a gradation presentation can be created in which the changes in other colors can be enjoyed as the distance from the main points increases.

Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the light-emitting section 8 has three light-emitting elements 8a, 8b, and 8c, but this is not limited to this configuration and may have two or four or more elements. Furthermore, the arrangement of the multiple light-emitting elements is not limited in any way to the arrangement shown in the figures above, and they can be arranged in an appropriate position depending on the arrangement and shape of the pattern section 10a.

In addition, in the above embodiment, the reflector 20 is configured to have a convex or concave shape, but this is not limited to this shape, and it may be configured to have a planar shape, or may be configured to have a combination of a curved surface and a planar surface.

In addition, in the above embodiment, the reflective surfaces (first reflective surface 21r, second reflective surface 22r) are configured to have a white color and a mirror finish, but this is not limited to the configuration, and the reflective surfaces may be configured, for example, with a plating finish.
