[Figure 3] This is a perspective view of the main body of the light fixture, showing it with the fixed decorative part removed. [Figure 4] This diagram shows the illuminated decorative section, with (A) being a front view and (B) being a rear view. [Figure 5] This is a cross-sectional view of the second decorative light section. [Figure 6] This is a rear perspective view of the main body of the light ornament, showing it with the battery box removed. [Figure 7] This is a front perspective view of the main body of the light ornament, showing it with the battery box removed. [Figure 8] This is a block diagram showing the functional configuration of the light decoration section. [Modes for carrying out the invention]

[0016] FIG. 1 is a perspective view of the optical ornament 10 according to the embodiment. In the following description, "left" and "right" refer to "left" and "right" as seen from a person wearing the optical ornament 10. When distinguishing, "left" at the end of the reference numeral is denoted as "L" and "right" as "{R}". Also, "front" and "rear" refer to the front side of the optical ornament 10 as "front" and the back side as "rear".

[0017] The optical ornament 10 is a chouxia - like optical ornament, and roughly includes a fastener (chouxia) 11 attached to the head, a fixed decoration part 12 attached to the fastener 11, optical decoration parts 13L and 13R, and additional decoration parts 14L and 14R. The additional decoration parts 14L and 14R are detachable and replaceable with respect to the main body of the optical ornament 10. The state (main body) with the additional decoration parts 14L and 14R removed is shown in FIG. 2.

[0018] The fastener 11 is formed in a substantially circular shape by an elastic material made of plastic, and due to this elasticity, it can be attached to and detached from a person's head.

[0019] FIG. 3 is a perspective view showing the main body of the optical ornament 10 with the fixed decoration part 12 removed. The fixed decorative part 12 is a decorative part whose form does not change. However, it may be decorated with holograms or glitter, so that its appearance changes depending on the reflection of light and the viewing direction. In this case, the fixed decorative part 12 is shaped to resemble the planar form of a crown. This fixed decorative part 12 comprises a main body part 12a and a central star-shaped part 12b. The star-shaped part 12b is movable and is mounted so as to be able to press the changeover switch 26a on the circuit board 20, which will be described later. The main body part 12a has a star-shaped hole 121 that corresponds to the star-shaped part 12b. The rear of the main body part 12a is attached to female threaded bosses 122L and 122R. Then, the main body portion 12a is attached to the fastener 11 by fitting the female threaded bosses 122L and 122R into the upper cylindrical bodies 111L and 111R of the fastener 11 and screwing the battery box 24 (described later) to the female threaded bosses 122L and 122R. When the main body portion 12a is attached to the fastener 11, the star-shaped portion 12b is exposed from the star-shaped hole 121. The star-shaped portion 12b has a step, and this step engages with the edge of the star-shaped hole 121 of the main body portion 12a, preventing the star-shaped portion 12b from falling off.

[0020] Figure 4(A) is a front view showing the light-decorating section 13L, and Figure 4(B) is a rear view showing the light-decorating section 13L. Note that the light-decorating section 13L and the light-decorating section 13R are symmetrical. Therefore, only the light-decorating section 13L will be explained, and the explanation of the light-decorating section 13R will be omitted as appropriate. The light-decorating section 13L is illuminated, for example, by light from a corresponding full-color LED 23L to produce a light pattern. Instead of the LED 23, a light-emitting part such as a miniature light bulb may be used. Each light-decorating section 13 (collectively referred to as light-decorating sections 13L and 13R) is provided with a first light-decorating section 131 which is roughly isosceles triangular in shape from the fixed decorative section 12, and a second light-decorating section 132 which is surrounded, except for a part, by the first light-decorating section 131.

[0021] The first light decorative section 131 is composed of a light guide tube bent into a roughly isosceles triangle shape, with the portion corresponding to the apex angle missing. The first light decorative section 131 is positioned so that the portion corresponding to the apex angle is located on the side of the fixed decorative section 12. In other words, the first light decorative section 131 is provided extending out from the fixed decorative section 12 so that both ends of the light guide tube are located on the side of the fixed decorative section 12. Female threaded bosses 134a and 134b are attached to the rear of the first light decorative section 131. The first light decorative section 131 and the second light decorative section 132 are screwed to the battery box 24 (see Figures 6 and 7) using these female threaded bosses 134a and 134b.

[0022] Furthermore, the second light decorative section 132 is composed of a light guide plate that is substantially similar in shape to the first light decorative section 131. The light guide plate is supported by the first light decorative section 131. On the front surface of the second light decorative section 132, star-shaped raised patterns 132a, 132b, 132c, and 132d are formed in a row in that order in the region surrounded by the first light decorative section 131. The raised patterns 132a, 132b, 132c, and 132d are similar in shape to each other and become progressively larger as they move away from the fixed decorative section 12. On the other hand, on the rear surface of the second light decorative section 132, star-shaped V-shaped grooves (recesses) 133a, 133b, 133c, and 133d are formed at positions corresponding to the outer edges of the star-shaped raised patterns 132a, 132b, 132c, and 132d. The depth of these grooves 133a, 133b, 133c, and 133d increases sequentially as they move away from the fixed decorative part 12.

[0023] Both ends of each first light decoration section 131 are positioned close to the corresponding LEDs 23 (collectively referred to as LEDs 23L and 23R), allowing light from the LEDs 23 to be introduced from both ends. Therefore, the light from each LED 23 spreads throughout a single light guide tube, illuminating the light guide tube uniformly. Furthermore, the end of the second light decoration section 132 is positioned opposite the corresponding LEDs 23L and 23R, allowing light from the LEDs 23L and 23R to be introduced from that end. In this case, the convex patterns 132a, 132b, 132c, and 132d are similar in shape to each other and increase in size sequentially as they move away from the fixed decoration section 12, so that the light that passes directly past the groove corresponding to each convex pattern can efficiently illuminate the next convex pattern. Moreover, the depth of the grooves 133a, 133b, 133c, and 133d increases sequentially as they move away from the fixed decoration section 12, so that the light that passes directly over each groove can be efficiently reflected by the wall surface of the next groove, thus efficiently illuminating each convex pattern.

[0024] Furthermore, the circuit board 20 is equipped with LEDs 23L and 23R, a changeover switch 26a, a chip such as a light emission control unit 52, and a power switch 26. A battery box 24 is provided at the rear of the circuit board 20. The battery box 24 houses, for example, AA batteries as a power source. On both the left and right sides of the battery box 24 are clamping parts 25L and 25R for clamping the bases of the additional decorative parts 14L and 14R. The clamping sections 25L and 25R consist of clamping pieces 26L and 26R fixed to the left and right sides of the battery box 24, and clamping pieces 27L and 27R that are screwed to the left and right sides of the battery box 24. The clamping pieces 26L, 26R, 27L, and 27R have saw-toothed teeth formed on them for clamping the additional decorative parts 14L and 14R. The teeth of clamping piece 26L and the teeth of clamping piece 27L come together to fix the base of the additional decorative part 14L, and the teeth of clamping piece 26R and the teeth of clamping piece 27R come together to fix the base of the additional decorative part 14R. The battery box 24 is screwed to the female threaded bosses 122L and 122R by male screws (not shown) inserted through holes 28L and 28R.

[0025] The decorative parts 14L and 14R are, for example, made by tying one end of organza fabric to form a ribbon. These decorative parts 14L and 14R can be replaced with different colors and fabrics according to preference.

[0026] Functional Configuration Figure 8 is a block diagram showing the functional configuration of the light ornament 10. The light ornament 10 has a functional configuration that includes an input unit 50, a storage unit 51, a light emission control unit 52, and a light output unit 53.

[0027] The input unit 50 includes a light emission mode change switch 26a. The change switch 26a is a push-button switch. Each time the star-shaped portion 12b is pressed, the light emission mode of the input unit 50 is changed. The signal from the input unit 50 is sent to the light emission control unit 52, which changes the light emission pattern (color, light emission mode) of the LEDs 23L and 23R.

[0028] The memory unit 51 is equipped with a storage device that allows data to be written to and read, such as flash memory. This memory unit 51 stores a program for light emission and light emission data necessary for executing that program.

[0029] The light emission control unit 52 is comprised of a microcontroller unit and peripheral circuits. The light emission control unit 52 reads each program from the storage unit 51 and performs processing and control according to each program.

[0030] The light output unit 53 is equipped with the LEDs 23L and 23R. This light output unit 53 controls the light output of LEDs 23L and 23R under the control of the light emission control unit 52.

[0031] (modified version) In the above embodiment, a headband-shaped light ornament 10 was used, but the invention is not limited to a headband-shaped light ornament.

[0032] Furthermore, in the above embodiment, V-shaped grooves (recesses) 133a, 133b, 133c, and 133d were formed at positions corresponding to the outer edges of the convex patterns 132a, 132b, 132c, and 132d. However, the recesses do not need to be a single continuous groove; multiple fine recesses may be arranged along the convex patterns 132a, 132b, 132c, and 132d. In this way, the angle of the wall surface of each recess can be changed, allowing the convex patterns 132a, 132b, 132c, and 132d to be illuminated even more efficiently.

[0033] Furthermore, in the above embodiment, the first light decoration section 131 is composed of a light guide tube bent into a substantially isosceles triangle shape, but it is not limited to this as long as it is a light guide member that can guide light inside. It is sufficient if it is a linear light decoration section that is open at both ends in a continuous line so that a predetermined space is formed inside, can guide light inside, and has both ends close together, and its shape and other characteristics are not considered.
