[0008] Problems to be solved by the invention

[0009] In Patent Documents 1 and 2, visible light is irradiated from a common lamp to the ornaments supported by the lower box body. Moreover, in a common environment, the visible light of natural light or electric light overflows around the jewelry box, thereby failing to produce the desired light performance effect.

[0010] The present invention is completed in view of the above actual situation, and its purpose is to provide a jewelry box that can give observers a feeling that they do not have otherwise through the performance effect of light.

[0011] Means for solving problems

[0012] According to a first aspect of the present invention, there is provided a jewelry box, comprising: a lower box body; a diamond supported by the lower box body and having blue fluorescence; an upper box body connected to the lower box body by a hinge in an openable and closable manner, and the upper box body is closed with the lower box body in a closed position to hide the diamond, and the diamond is exposed in an open position; and a light source supported by the lower box body or the upper box body, irradiating ultraviolet rays toward the diamond when the upper box body is opened from the closed position.

[0013] According to a second aspect, in addition to the structure of the first aspect, the light source emits light other than visible light.

[0014] According to a third aspect, based on the structure of the second aspect, the light source has directivity that is blocked by the lower box body and the upper box body in the entire irradiation area.

[0015] According to a fourth aspect of the present invention, there is provided a jewelry box comprising: a lower box body; a diamond supported by the lower box body and having blue fluorescence; an upper box body connected to the lower box body by a hinge in an openable and closable manner, and the upper box body is closed with the lower box body in a closed position to hide the diamond, and the diamond is exposed in an open position; and a light source supported by the lower box body or the upper box body, and irradiates ultraviolet rays toward the diamond when the upper box body reaches the open position and a predetermined time has passed.

[0016] According to a fifth aspect, in addition to the structure of the fourth aspect, the light source emits light other than visible light.

[0017] According to a sixth aspect, based on the structure of the fifth aspect, the light source has directivity that is blocked by the lower box body and the upper box body in the entire irradiation area.

[0018] According to a seventh aspect of the present invention, there is provided a jewelry box comprising: a lower box body; a diamond supported by the lower box body and having blue fluorescence; an upper box body connected to the lower box body by a hinge in an openable and closable manner, and the upper box body is closed with the lower box body in a closed position to hide the diamond, and the diamond is exposed in an open position; and a light source supported by the lower box body or the upper box body, and after the upper box body reaches the open position, the light amount is gradually increased while irradiating ultraviolet rays toward the diamond.

[0019] According to an eighth aspect, in addition to the structure of the seventh aspect, the light source emits light other than visible light.

[0020] According to a ninth aspect, based on the structure of the eighth aspect, the light source has directivity that is blocked by the lower box body and the upper box body in the entire irradiation area.

[0021] Effects of the Invention

[0022] According to the first aspect, when the upper box body is opened from the closed position, ultraviolet rays are irradiated toward the diamond. The diamond emits blue light. The diamond emitting blue light enters the field of vision of the observer. The diamond with blue fluorescence, which is not usually seen, causes the observer to feel surprised. When the diamond is taken out of the jewelry box, the diamond emits transparent light under visible light (natural light or light from electric lamps). By irradiating ultraviolet rays and visible light in sequence, a light performance effect such as the color change of the diamond is produced. This performance effect can give the observer of the jewelry box a feeling that is not otherwise available.

[0023] According to the second aspect, the light emitted from the light source is not visually recognized by the observer of the diamond, so only the blue fluorescence of the diamond emerges, which can further enhance the performance effect.

[0024] According to the third aspect, in addition to the light that is transformed into blue visible light by the fluorescence of the diamond, the ultraviolet rays do not leak to the outside of the jewelry box, so the observer of the jewelry box is not exposed to the influence of the ultraviolet rays.

[0025] According to the fourth aspect, when the upper box body reaches the open position, the diamond is exposed. Under visible light (natural light or electric light), the diamond emits transparent brilliance. When the upper box body reaches the open position and a predetermined time has passed, ultraviolet rays are irradiated from the light source to the diamond. The diamond changes color from transparent to blue. In this way, a light performance effect is produced according to the opening action of the upper box body. This performance effect can give the observer of the jewelry box a feeling that is not available elsewhere.

[0026] According to the fifth aspect, the light emitted from the light source is not visually recognized by the observer of the diamond, so only the blue fluorescence of the diamond emerges, and the performance effect can be further improved.

[0027] According to the sixth aspect, except for the light that is transformed into blue visible light by the fluorescence of the diamond, the ultraviolet rays do not leak to the outside of the jewelry box, so the observer of the jewelry box is not exposed to the influence of the ultraviolet rays.

[0028] According to the seventh aspect, when the upper box body is opened from the closed position, the diamond is exposed. Under visible light (natural light or light from an electric lamp), the diamond emits a transparent glow. After the upper box body reaches the open position, ultraviolet rays are irradiated from the light source to the diamond. As the amount of ultraviolet light increases, the diamond gradually changes color from transparent to blue. In this way, a light performance effect is produced according to the opening action of the upper box body. This performance effect can give the observer of the jewelry box a feeling that is not available elsewhere.

[0029] According to the eighth aspect, the light emitted from the light source is not visually recognized by the observer of the diamond, so only the blue fluorescence of the diamond emerges, and the performance effect can be further improved.

[0030] According to the ninth aspect, except for the light that is transformed into blue visible light by the fluorescence of the diamond, the ultraviolet rays do not leak to the outside of the jewelry box, so the observer of the jewelry box is not exposed to the influence of the ultraviolet rays.

[0042] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0043] Figure 1A jewelry box 11 according to an embodiment of the present invention is schematically shown. The jewelry box 11 has a lower box body 12 and an upper box body 13, wherein the upper box body 13 overlaps with the lower box body 12 and forms a rectangular parallelepiped together with the lower box body 12. The lower box body 12 has a hard resin molded body and a sticker 15, wherein the hard resin molded body has a bottom plate 14a with a quadrilateral outline and four side walls 14b vertically rising from four sides of the bottom plate 14a, and the sticker 15 is pasted on the outer surface of the resin molded body to decorate the resin molded body. The upper box body 13 has a hard resin molded body and a sticker 17, wherein the hard resin molded body has a top plate 16a with a quadrilateral outline and side walls 16b, wherein the side walls 16b descend from the four sides of the top plate 16a and close at the lower end with the upper end of the side wall 14b of the lower box body 12, thereby forming the side wall of the jewelry box 11, and the sticker 17 is pasted on the outer surface of the resin molded body to decorate the resin molded body. The stickers 15 and 17 may be made of, for example, suede-like or cloth-like materials.

[0044] like Figure 2 As shown, a cushioning material 18 is embedded in the rectangular space surrounded by the side wall 14b in the lower box body 12. The cushioning material 18 is formed of, for example, a sponge and a cloth material 18a wrapped in the sponge. A slit 19 is formed in the cushioning material 18. For example, a ring 21 is inserted into the slit 19. The ring 21 is held in the slit 19 by the elastic force of the cushioning material 18.

[0045] The ring 21 has, for example, a platinum ring member 22 and a diamond particle 23 fixed to a base of the ring member 22, wherein the ring member 22 has a diameter corresponding to the thickness of the finger. The diamond particle 23 may be one or more. The diamond particle 23 has a blue fluorescence property that is strong or above (strong blue fluorescence or very strong blue fluorescence). The diamond particle 23 emits a transparent glow under visible light (such as natural light or light from an electric lamp), and emits a blue glow under ultraviolet light. In this way, the diamond particle 23 is supported by the lower box body 12.

[0046] The lining material 24 is embedded in the rectangular space surrounded by the side wall 16b in the upper box body 13. The lining material 24 has a decorative top plate 24a with a quadrilateral outline and four lining plates 24b. The decorative top plate 24a forms the top surface of the jewelry box 11, and the lining plates 24b are respectively continuous from the four sides of the decorative top plate 24a and overlap with the four side walls 16b from the inside. Here, the four lining plates 24b are not bonded to the inner surface of the side wall 16b, and the lining material 24 is stored in a manner that can be freely loaded and unloaded relative to the upper box body 13.

[0047] like Figure 3As shown, the upper box body 13 is connected to the lower box body 12 in a freely openable and closable manner by a hinge 26. The hinge 26 comprises: a first blade 27, which is fixed to a side wall 16b of the upper box body 13 from the inside in an overlapping manner and has a plurality of tube bodies 27a; a second blade 28, which is fixed to the side wall 14b of the lower box body 12 from the inside in an overlapping manner and has a plurality of tube bodies 28a arranged in an alternating manner with the tube body 27a of the first blade 27; and a hinge pin 29, which is inserted into the tube body 27a of the first blade 27 and the tube body 28a of the second blade 28. The first blade 27 and the second blade 28 rotate relative to each other around the hinge pin 29.

[0048] A leaf spring 31 is connected to the hinge 26. Figure 4 As shown, the leaf spring 31 is formed into a curved body that maintains a generatrix parallel to the axis of the hinge pin 29. Both ends of the leaf spring 31 are respectively connected to the first blade 27 and the second blade 28 at positions away from the hinge pin 29. In the closed position where the lower end of the upper box body 13 and the upper end of the lower box body 12 are closed, the first blade 27 and the second blade 28 are arranged along a surface, and the middle area of ​​the leaf spring 31 is farthest from the hinge pin 29 to the inside. As the upper box body 13 moves from the closed position to the open position around the hinge pin 29, the outer angle between the first blade 27 and the second blade 28 becomes smaller, so that the middle area of ​​the leaf spring 31 approaches the hinge pin 29. Figure 5 As shown, when the middle area of ​​the leaf spring 31 contacts the hinge pin 29, the displacement of the upper box body 13 relative to the lower box body 12 around the hinge pin 29 is restricted, so that the open position of the upper box body 13 is specified. When the opening around the hinge pin 29 is less than the specified middle opening, the leaf spring 31 acts on the upper box body 13 toward the closed position. When the opening is greater than the specified middle opening, the leaf spring 31 acts on the upper box body 13 toward the open position. The hinge 26 and the leaf spring 31 are covered by a hinge cover 32. The hinge cover 32 is formed of, for example, the same raw material as the cloth material 18a of the cushioning material 18.

[0049] An LED lamp (light source) 33 that emits ultraviolet light in accordance with a predetermined directivity Dv is embedded in the decorative top plate 24a of the upper box body 13. The LED lamp 33 emits, for example, long-wavelength UV-A (wavelength of 315nm to 400nm). It is preferred that the LED lamp 33 emits only light other than visible light. It is preferred that the LED lamp 33 has a narrow directivity Dv. The LED lamp 33 has a directivity Dv that is blocked by the lower box body in the entire irradiation area.

[0050] The LED lamp 33 is connected to a battery 35, which is stored in a battery chamber 34 defined between the top plate 16a of the resin molded body and the decorative top plate 24a. The battery 35 may be, for example, a thin button cell. Here, for example, a plurality of button cells are connected in series. The battery 35 supplies current to the LED lamp 33.

[0051] A switch 36 is assembled on the hinge 26 and the leaf spring 31, and the switch 36 controls the supply and cutoff of current to the LED lamp 33. A first contact 37 electrically insulated from the leaf spring 31 is fixed in the middle area of ​​the leaf spring 31. The hinge 26 functions as a second contact that cooperates with the first contact 37 to constitute the switch 36. Therefore, the hinge 26 is formed of a conductive material. The first contact 37 is formed of a conductive material such as copper. An insulator is sandwiched between the first contact 37 and the leaf spring 31. The first contact 37 is arranged on the surface facing the hinge pin 29 at the leaf spring 31. The first contact 37 contacts the hinge 26 at the open position of the upper box body 13 and is away from the hinge 26 at places other than the open position.

[0052] like Figure 6 As shown, in the jewelry box 11, an electronic circuit 38 of the first specific example including an LED lamp 33, a battery 35 and a switch 36 is constructed. In the electronic circuit 38, the LED element of the LED lamp 33 is connected in series to the battery 35. The switch 36 and the timer time-limited normally closed contact (hereinafter referred to as "normally closed contact") 39 are connected in series to the LED lamp 33. A timer 41 is connected in parallel to the LED lamp 33 and the normally closed contact 39. When the switch 36 is turned on, the LED lamp 33 is energized and lights up. The timer 41 operates simultaneously with the conduction of the switch 36, and opens the normally closed contact 39 after a predetermined time. As a result, the LED lamp 33 is turned off. When the switch 36 is turned on, the timer 41 is reset and the LED lamp 33 is turned off.

[0053] In the electronic circuit 38, the LED lamp 33, the normally closed contact 39, and the timer 41 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, etc. may be electrically connected to the wiring pattern on the printed circuit board through an electric wire such as a vinyl coated wire, for example. The printed circuit board may be housed in the battery chamber 34, for example.

[0054] Next, the function of the jewelry box 11 is described. Figure 1 As shown, when the upper box body 13 is in the closed position, the lower edge of the upper box body 13 is closed with the upper edge of the lower box body 12. The upper box body 13 covers the ring 21 to hide the diamond grains 23. The observer of the jewelry box 11 visually confirms the appearance of the closed jewelry box 11. The diamond grains 23 are out of the observer's field of vision.

[0055] At this time, if Figure 4 As shown, the middle area of ​​the leaf spring 31 is farthest from the hinge pin 29. Therefore, the first contact 37 of the switch 36 is far away from the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 is disconnected.

[0056] When the observer overcomes the elastic force of the leaf spring 31 and moves the upper box body 12 toward the open position around the hinge pin 29, the lower end of the upper box body 13 leaves the upper end of the lower box body 12. Visible light (natural light or light from an electric lamp) is emitted from the gap between the upper box body 13 and the lower box body 12 toward the diamond grains 23. The diamond grains 23 are gradually exposed. The diamond grains 23 are exposed to the irradiation of the visible light. Therefore, the diamond grains 23 emit transparent brilliance.

[0057] When the opening of the upper box body 13 is larger than the specified intermediate opening, the leaf spring 31 drives the upper box body 13 toward the open position. As a result, the upper box body 13 reaches the open position with the maximum opening. The upper box body 13 is maintained in the open position by the elastic force of the leaf spring 31. Figure 2 As shown, the observer can visually confirm the diamond grains 23 without being blocked by the upper box body 13.

[0058] When the upper box body 13 reaches the open position, Figure 5 As shown, the middle area of ​​the leaf spring 31 is subjected to the elastic force of the leaf spring 31 and abuts against the hinge 29. In this way, the first contact 37 contacts the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 is turned on. The LED lamp 33 is lit. The LED lamp 33 irradiates ultraviolet light to the diamond grains 23. The diamond grains 23 emit blue light.

[0059] Thus, when the upper box body 13 is opened from the closed position, the diamond grains 23 emitting blue light enter the view of the observer. The blue fluorescence of the diamond grains 23, which is not usually seen, arouses the observer's emotion of surprise. When the ring 21 is taken out of the jewelry box 11, the diamond grains 23 emit transparent light under visible light (natural light or light from electric lamps). By sequentially irradiating ultraviolet light and visible light in this way, a light performance effect such as the color change of the diamond grains 23 is produced. This performance effect can give the observer of the jewelry box 11 a feeling that is not otherwise felt.

[0060] In the electronic circuit 38, the timer 41 operates according to the conduction of the switch 36. When the upper box body 13 reaches the open position and a predetermined time has passed, the normally closed contact 39 is opened. As a result, the LED lamp 33 is turned off. After the diamond grains 23 emitting blue light are observed for a moment after the upper box body 13 is opened, the diamond grains 23 change color from blue to transparent. When the upper box body 13 is closed from the open position and the switch 36 is turned off, the LED lamp 33 is turned off.

[0061] Here, the LED lamp 33 emits light other than visible light. The light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, so only the blue fluorescence of the diamond grains 23 emerges, which can further enhance the performance effect.

[0062] The LED light 33 has a directivity Dv that is shielded in the entire irradiation area by the lower box body 12. In addition to the light that changes into blue visible light through the fluorescence of the diamond grains 23, the ultraviolet light does not leak to the outside of the jewelry box 11, so the observer of the jewelry box 11 is not exposed to the influence of the ultraviolet light.

[0063] In the electronic circuit 38, a normally closed momentary switch (tactile switch) may be used instead of the switch 36. When the upper box body 13 overlaps with the lower box body 12 at the closed position, the momentary switch opens the contact. When the upper box body 13 leaves the closed position, the LED light 33 immediately lights up according to the stroke of the momentary switch. The diamond grains 23 emitting blue light enter the viewer's field of vision at the same time as the upper box body 13 is opened. The diamond grains 23 with blue fluorescence, which are not usually seen, cause the observer to feel surprised. When the diamond grains 23 are taken out of the jewelry box 11, the diamond grains 23 emit transparent light under visible light (natural light or light from electric lamps). By irradiating ultraviolet rays and visible light in sequence, a light performance effect such as the color change of the diamond grains 23 is produced. This performance effect can give the observer of the jewelry box a feeling that is not available elsewhere.

[0064] Figure 7 The structure of the electronic circuit 43 of the second specific example is schematically shown. In the electronic circuit 43, the LED element of the LED lamp 33 is connected in series to the battery 35. A timer time-limited normally open contact (hereinafter referred to as "normally open contact") 44 is connected in series to the LED lamp 33. A switch 36 and a timer 45 are connected in parallel to the LED lamp 33 and the normally open contact 44. When the switch 36 is turned on, the timer 45 operates and closes the normally open contact 44 after a predetermined time. As a result, the LED lamp 33 is energized. When the switch 36 is opened, the timer 45 is reset and the normally open contact 44 is opened. As a result, the LED lamp 33 is turned off.

[0065] In the electronic circuit 43, the LED lamp 33, the normally open contact 44, and the timer 45 are mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, etc., can be electrically connected to the wiring pattern on the printed circuit board through an electric wire such as a vinyl coated wire. The printed circuit board can be stored in the battery chamber 34, for example.

[0066] When the upper box body 13 reaches the open position, the switch 36 of the electronic circuit 43 is turned on, but the lighting of the LED lamp 33 is controlled before a predetermined time has passed. Figure 2As shown, in an instant, the observer can visually confirm the diamond grains 23 emitting transparent light without being blocked by the upper box body 13. When a predetermined time has passed since the switch 36 was turned on (switched on), the LED lamp 33 is lit. The LED lamp 33 irradiates ultraviolet light to the diamond grains 23. Therefore, the diamond grains 23 emit blue light. In this way, after the diamond grains 23 emitting transparent light are observed for a moment after the upper box body 13 is opened, the diamond grains 23 change color from transparent to blue. A light performance effect is produced according to the opening action of the upper box body 13. This performance effect can give the observer of the jewelry box 11 a feeling that is not otherwise felt. When the switch 36 is turned off, the LED lamp 33 is turned off.

[0067] Here, the LED lamp 33 emits light other than visible light. The light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, so only the blue fluorescence of the diamond grains 23 emerges, which can further enhance the performance effect.

[0068] The LED light 33 has a directivity Dv that is shielded in the entire irradiation area by the lower box body 12. In addition to the light that changes into blue visible light through the fluorescence of the diamond grains 23, the ultraviolet light does not leak to the outside of the jewelry box 11, so the observer of the jewelry box 11 is not exposed to the influence of the ultraviolet light.

[0069] Figure 8 The structure of the electronic circuit 47 of the third specific example is schematically shown. The electronic circuit 47 has an NPN transistor TR1 connected to a battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R1 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C1 and a second resistor R2 are connected in series between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The third resistor R3 is connected in parallel with the first resistor R1, the capacitor C1, and the second resistor R2. A fourth resistor R4 is connected between the emitter E of the NPN transistor TR1 and the negative terminal of the battery 35. In the electronic circuit 47, when the switch 36 is energized, a voltage exceeding the threshold is applied to the base B of the NPN transistor TR1 by the action of the second resistor R2. Therefore, a current flows into the collector C of the NPN transistor TR1 instantaneously. The voltage applied to the base B of the NPN transistor TR1 gradually increases due to the action of the time constant circuits R1 and C1. When a predetermined time has passed, the voltage applied to the base B of the NPN transistor TR1 is maintained constant. When the switch 36 is turned off, the charge of the capacitor C1 is discharged through the third resistor R3.

[0070] In the electronic circuit 47, the LED lamp 33, the NPN transistor TR1, the capacitor C1, and the first to fourth resistors R1 to R4 can be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, etc. can be electrically connected to the wiring pattern on the printed circuit board through an electric wire such as a vinyl coated wire. The printed circuit board can be stored in the battery chamber 34, for example.

[0071] When the upper case 13 reaches the open position, the switch 36 of the electronic circuit 38 is turned on. According to the turning on (on operation) of the switch 36, a voltage is applied from the battery 35 to the base B of the NPN transistor TR1 in the electronic circuit 38. Current flows into the base B of the NPN transistor TR1, and the LED lamp 33 starts to light up.

[0072] Through the action of the time constant circuits R1 and C1, the voltage applied to the base B of the NPN transistor TR1 gradually increases. The amount of current flowing in the LED lamp 33 gradually increases. The amount of ultraviolet light irradiated from the LED lamp 33 to the diamond grains 23 increases. The diamond grains 23 gradually change color from transparent to blue. In this way, a light performance effect is produced according to the opening action of the upper box body 13. This performance effect can give the observer of the jewelry box 11 a feeling that is not otherwise available. When the switch 36 is turned off, the charge of the capacitor C1 is discharged through the third resistor R3.

[0073] Here, the LED lamp 33 emits light other than visible light. The light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, so only the blue fluorescence of the diamond grains 23 emerges, which can further enhance the performance effect.

[0074] The LED light 33 has a directivity Dv that is shielded in the entire irradiation area by the lower box body 12. In addition to the light that changes into blue visible light through the fluorescence of the diamond grains 23, the ultraviolet light does not leak to the outside of the jewelry box 11, so the observer of the jewelry box 11 is not exposed to the influence of the ultraviolet light.

[0075] Fig. 9The structure of the electronic circuit 48 of the fourth specific example is schematically shown. The electronic circuit 48 has an NPN transistor TR1 connected to a battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R5 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C2 is connected between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The second resistor R6 is connected in parallel with the first resistor R5 and the capacitor C2. The emitter E of the NPN transistor TR1 is connected to the negative terminal of the battery 35. In the electronic circuit 48, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R5 and C2. When the voltage at the base B of the NPN transistor TR1 reaches a specified value, a current flows into the collector C. Then, when a predetermined time has passed, the voltage applied to the base B of the NPN transistor TR1 is maintained constant. When the switch 36 is turned off, the charge of the capacitor C2 is discharged through the second resistor R6.

[0076] In the electronic circuit 48, the LED lamp 33, the NPN transistor TR1, the capacitor C2, and the first and second resistors R5 and R6 can be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, etc. can be electrically connected to the wiring pattern on the printed circuit board through an electric wire such as a vinyl coated wire. The printed circuit board can be stored in the battery chamber 34, for example.

[0077] In the electronic circuit 48 of the fourth specific example, after the upper case 13 reaches the open position and the switch 36 is turned on, after the switch 36 is turned on (on operation), a predetermined time is waited for, and a voltage of a predetermined value is applied from the battery 35 to the base B of the NPN transistor TR1. Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 starts to light up. Therefore, the observer of the jewelry box 11 can observe the diamond grains 23 that emit a momentary transparent glow after the upper case 13 is opened.

[0078] Through the action of the time constant circuits R5 and C2, the voltage applied to the base B of the NPN transistor TR1 gradually increases. The amount of current flowing in the LED lamp 33 gradually increases. The amount of ultraviolet light irradiated from the LED lamp 33 to the diamond grains 23 increases. The diamond grains 23 gradually change color from transparent to blue. In this way, a light performance effect is produced according to the opening action of the upper box body 13. This performance effect can give the observer of the jewelry box 11 a feeling that is not otherwise there. When the switch 36 is turned off, the charge of the capacitor C2 is discharged through the second resistor R6.

[0079] In addition, the LED lamp 33 may be supported by the lower box body 12 instead of being supported by the upper box body 13. In this case, the LED lamp 33 only needs to have a directivity Dv that is blocked by the upper box body 13 in the entire irradiation area. In addition, the diamond grains 23 may also be mounted on multiple pedestals that form a necklace chain. The pedestals are formed of a metal material such as platinum or gold. One diamond grain 23 may be fixed to each pedestal, or multiple diamond grains 23 may be fixed. In addition, the diamond grains 23 may also be decorated on pendants or bracelets, earrings, finger rings, and anklets. The diamond grains may be of uniform size or of mixed sizes.

[0080] In the above-mentioned jewelry box 11, the switch 36 may also be a tactile switch having a plunger that is pressed by the upper box body 13 when the upper box body 13 reaches the open position. The electronic circuit 38 of the first specific example or the electronic circuit 43 of the second specific example may also be replaced by an electronic circuit of another structure as long as it can achieve the same functions as described above. In addition, as described above, the action of the switch 36 may be linked to the upper box body 13 in the open position or to the upper box body 13 in the closed position. In addition, the functions of the electronic circuits 38, 43, 47, and 48 may also be implemented by software executed by a microprocessor (MPU).
