DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a coaster 1 as a first embodiment of a mounting table that emits decorative light. As is known, the coaster 1 is generally used as an underlay of the cup A containing the beverage (see FIG. 9).

As shown in FIGS. 1 and 2, the coaster 1 has a disk-shaped support substrate 2 having a thickness of several mm. The support substrate 2 is mainly configured by a printed circuit board on which an electric circuit 18 (see FIG. 3) having a switch 4 as an input unit and a light emitting diode (hereinafter, referred to as an LED) 6 is mounted. The battery 8 serving as a power source of the electric circuit 18 is detachably attached to the support substrate 2. That is, the support substrate 2 is formed as a base of the coaster 1 that supports the electric elements 4, 6, and 8.

On the surface of the supporting substrate 2, electric elements 4, 6,
A cover (top sheet) 10 is attached with an adhesive or the like so as to cover 8 from above. This cover 10
A flat mounting surface on which a mounted object (object to be decorated), for example, a cup is mounted is formed. A packing 14 is attached to the periphery of the support substrate 2 so as to seal the joint between the cover 10 and the support substrate 2.

A portion of the cover 10 facing the switch 4 forms a projection 12. The convex portion 12 protrudes upward from the other flat mounting surface by a predetermined height H so as to form a concave portion 15 on the lower surface thereof. For example, the convex portion 12 is formed so as to be crushed by a light force. I have. In addition, the protrusion 12 has a cover 10 side (recess 15) from the support substrate 2.
The switch 4 protrudes from the lower side. That is, the force for crushing the convex portion 12 is transmitted to the switch 4 as it is. Note that a slight clearance may be formed between the protrusion 12 and the switch 4.

The switch 4 is formed so as to be able to operate by a physical external force (for example, the weight of a cup (including a beverage)) placed on the cover 10 to crush the convex portion 12. . Specifically, the operating point (force) of the switch 4 is set in the range of 50 gf to 150 gf, and the operating direction of the switch 4 is set in the normal direction (vertical direction) of the coaster 1. Further, the protrusion height H of the projection 12 is set in the range of 0.5 mm to 1.0 mm, and the switch 4
Is set in the range of 0.3 mm to 0.5 mm. For example, when the protrusion height H of the protrusion 12 is 0.5 mm and the stroke of the switch 4 is 0.5 mm, the protrusion 12 is crushed and is flush with other flat mounting surfaces. At this point, the switch 4 is turned on. When the protrusion height H of the protrusion 12 is 0.5 mm and the stroke of the switch 4 is 0.3 mm, the protrusion 12 is crushed and its height is 0.2 mm from the flat mounting surface. At this point, the switch 4 is turned on.

The cover 10 has a light-transmitting portion 11 at a central portion facing the LED 6. Translucent part 11
Is formed of a transparent material, and transmits light emitted from the LED 6 to the outside. In the present embodiment, L
Since the light emission direction of the ED 6 is set in the normal direction of the coaster 1 (vertically upward), the light emitted from the LED 6 passes through the light transmitting portion 11 vertically upward.

Further, the light transmitting portion 11 and the convex portion 12 are arranged with a distance such that the switch 4 is operated in a state where the cup is placed on the light transmitting portion 11. Specifically, the planar distance between the light transmitting part 11 and the convex part 12 is 15 mm.
It is set in the range of ３０30 mm.

The configuration of the electric circuit 18 is shown in FIG. As illustrated, the electric circuit 18 is configured by connecting a battery 8, a current limiting resistor 20, an LED 6, and a switch 4 in series. In particular, in the present embodiment, two lithium primary batteries 8 are used, and one blue LED 6 emitting blue light is used. When two lithium primary batteries 8 are used, the blue LE
Since V _F (forward voltage) of D6 is about 3.2 V, the current limiting resistor 20 has a resistance of 40Ω (I _F ≒ 50 mA) to 160Ω.
(I _F Ｉ20 mA) is appropriate.

Next, the operation of the coaster 1 having the above configuration will be described. The transparent cup containing the beverage is placed on the mounting surface (cover 1) of the coaster 1 so as to cover the light transmitting portion 11.
0) When placed on the upper side, the convex portion 12 is crushed by its weight, and the switch 4 is turned on. Therefore, battery 8
Forward voltage V _F to LED6 is applied from, LED6 emits light. As shown in FIG. 9, the light of a predetermined color (blue in the present embodiment) emitted from the LED 6 is transmitted through the light-transmitting portion 11 and illuminates the glass A and the beverage contained therein from directly below to decorate the glass. I do. In this case, if the cup A contains a carbonated beverage or ice, the decorative effect can be further enhanced due to a difference in the refractive index of carbonic acid bubbles and ice, or irregular scattering of light.

As described above, the coaster 1 of the present embodiment is configured by attaching the cover 10 as a mounting surface on the support substrate 2 having the LEDs 6 and transmitting the light emitted from the LEDs 6. Translucent part 11
On the cover 10, it is possible to decorate a placed object such as a cup placed on the cover 10 with light. In particular, the decorative light emitted from the LED 6 in the dim room illuminates the mounted object more beautifully, and creates an exquisite atmosphere.

In the coaster 1 of the present embodiment, the LED 6 emits light when an object such as a glass is placed on the cover 10. Specifically, the switch 4 is operated by the weight of the object placed on the cover 10, and the LED 6 emits light. Therefore, the mounted object and the beverage in the mounted object can be decorated with light without wasting the battery 8 and simply mounting the mounted object on the coaster 1.

In this embodiment, the LED 6 may be configured as shown in FIG. That is,
The LED 6 shown in FIG. 4 includes an LED chip 6a and a transparent resin 6b whose upper surface has a convex lens shape and covers and seals the LED chip 6a. According to the LED 6 having such a configuration, an image such as a cup on the coaster 1 or ice or the like in the cup is formed on the ceiling by the light emitted from the LED chip 6a through the convex transparent resin 6b. Therefore, a beautiful light effect can be obtained.

In the present embodiment, the projection 12 and the switch 4 may be provided on the back surface of the coaster 1. If the convex portion 12 and the switch 4 are on the front side of the coaster 1, that is, on the cover 10, the switch 4 is turned on / off depending on the position of the object placed on the cover 10.
May become unstable, but the protrusion 12 and the switch 4
Is installed on the back side of the coaster 1, the switch 4 can operate only by the weight of the mounted object regardless of the position of the mounted object, so that the switch 4 is stably turned ON / OFF.

Further, in the present embodiment, it is preferable to provide a mirror on the surface of the cover 10 of the coaster 1 or to make the surface of the cover 10 a mirror surface. Thus, by making the surface of the cover 10 a mirror surface,
The light reflected from the mirror surface can also be applied to the object to be placed, and the decorativeness due to the complicatedly disturbed light is enhanced, and the design is excellent.

FIG. 5 shows a first modification of the electric circuit for causing the LED 6 to emit light. The electric circuit 18A is configured by connecting an electromagnetic wave receiving coil 21 as an input unit, a rectifying diode 22, a current limiting resistor 20, and an LED 6 in series. That is,
Unlike the electric circuit 18 in the above-described embodiment, there is no switch 4 and no battery 8.

In such an electric circuit 18A, when an electromagnetic wave of a predetermined frequency is oscillated from, for example, a transmission source incorporated in a table or the like, the electromagnetic wave is received by the electromagnetic wave receiving coil 21, and a current flows through the electric circuit 18A. That is, the forward voltage V _F is applied to the LED 6, LED 6 emits light.

As described above, if an electric circuit configuration in which the LED 6 can emit light by receiving an electromagnetic wave of a predetermined frequency is adopted, a power source is not required, so that it is not necessary to replace the battery, and it is not necessary to replace the battery without contact. The blinking and dimming of the LED 6 can be controlled by a signal (power supply radio wave). For example, by simultaneously controlling a plurality of devices according to the present modification, it is possible to produce a beautiful lighting effect.

If the receiving band of the coil 21 is tuned to the frequency band of the mobile phone, the incoming of the mobile phone can be known by the emission of the LED 6.

FIG. 6 shows a second modification of the electric circuit for causing the LED 6 to emit light. This electric circuit 18B
It has a control circuit 25 for controlling the blinking and dimming of the ED 6. Specifically, the electric circuit 18B corresponds to the electric circuit 1 in FIG.
8 is connected to a control circuit 25 in series. FIG. 7 shows a third modification of the electric circuit that causes the LED 6 to emit light. This electric circuit 18C
The control circuit 25 is connected in series to the electric circuit 18A of FIG.

The electric circuits 18B and 18C shown in FIGS.
The control circuit 25 provided for the LED 6 blinks the LED 6 in a time-division manner. In this case, by changing the period (frequency) of the time division, it is possible to make the firing, that is, the foam in the liquid in the transparent cup placed on the coaster 1 look beautiful. Also, in this case, if the blinking cycle of the LED 6 is synchronized with the rising speed of the bubble in a strobe manner, the bubble stops or
Alternatively, the bubbles can appear to be falling.

In each of the electric circuits 18, 18A, 18B, and 18C shown in FIGS. 3, 5, 6, and 7, a plurality of LEDs 6 may be provided. For example, RGB LED
Can also be adopted. In this case, if the LED (Red, Green, Blue) is selectively lit by changing the frequency of the electromagnetic wave to be transmitted and the applied forward voltage, the object can be mounted with light of a plurality of colors (wavelengths). Can be decorated. In particular, in the circuit configurations of FIGS. 6 and 7,
By controlling the dimming of a plurality of LEDs by the control circuit 25,
It is also possible to create color changes continuously, such as the spectrum of white light or a rainbow.

The technical contents described above can be applied not only to the coaster 1 but also to various mounting tables on which objects are mounted. For example, the above-described technical idea can be applied to a table itself on which a placed object such as a cup is placed or a placing table on which a crystal ornament is placed. In this case, the glass and crystal ornaments are decorated by the light emitted from the table or the table. Specifically, if the technical contents shown in FIGS. 1 to 3 are applied to the table, the switch 4 is turned on just by placing the crystal ornament on the table, and the crystal decoration is turned on by the light from the LED 6. The goods are decorated. Further, in the technical contents shown in FIG. 5, a crystal ornament is decorated by inputting an electromagnetic wave. 6 and 7, the control circuit 25 controls the LE.
The blinking / dimming of D6 is controlled.

The technical contents described above can also be applied to the decoration itself. FIG. 8 shows, for example, a luminous ornament used by being buried in a tropical fish tank. The light emitting decoration 30 shown in FIG. 8A has a substantially rectangular parallelepiped shape, and a part or the whole thereof is formed of a light transmissive material. The light-emitting decoration 31 shown in FIG. 8B has a substantially mountain shape, and a part or the whole thereof is formed of a light-transmitting material. Of course, it is not limited to these shapes.

At least one LED 6 is embedded in each of the light emitting decorations 30 and 31. As an electric circuit for causing the LED 6 to emit light, for example, a circuit configuration as shown in FIG. 5 or FIG. 7 is employed. That is, the LED 6 is turned on not by the switch 4 but by an electromagnetic wave. 10 to 1

On the surface of the support substrate 2, a translucent resin cover (surface sheet) 10 that has been subjected to diffuse reflection processing (washing treatment) is adhered by an adhesive or the like. The cover 10 forms a flat mounting surface on which, for example, a cup as a mounting object (object to be decorated) is mounted. Further, as shown in detail in FIG. 10, a plurality of annular grooves 40 are formed concentrically on the back surface of the support substrate 2, so that a plurality of annular grooves 41 are formed concentrically.

As clearly shown in FIG.
D6 has a light-emitting portion exposed on the surface of the support substrate 2, so that light from the LED 6 is transmitted to the outside through the translucent resin cover 10.
In addition, on the surface of the support substrate 2, there is provided a reflection surface 49 which is inclined so as to surround the light emitting portion of the LED 6. When the reflection surface 49 is formed so as to surround the LED 6 in this way, the light reflected from the reflection surface 49 can be applied to the object, and the decorativeness due to the complicatedly disturbed light is enhanced, and the design is excellent. The support substrate 2 has an electric circuit 18D.
The two lithium primary batteries 8 forming the power supply are detachably mounted. That is, the battery housing in which the batteries 8, 8 can be detachably set is provided substantially at the center of the back surface of the support substrate 2 by the two partition walls 44A, 44B curved in an arc shape and the rib 45 extending so as to connect them. Parts 42A and 42B are formed. 13 and 14 show the configuration of the electric circuit 18. As shown in FIG. 13, the electric circuit 18 </ b> D includes two lithium primary batteries 8, 8 and a current limiting resistor 20 (１ ／ W or ８ W) having a resistance value that is five times or more the internal resistance of the battery 8.
W), an LED 6, and a switch plate 52 that connects the two lithium primary batteries 8, 8 so that they can be electrically turned on / off. Specifically, as shown in FIG. 14, the LED 6 and the current limiting resistor 20 are mounted on the printed circuit board P, and a pair of conductive plates 50,
51 is extended. The conductive plates 50 and 51 are provided corresponding to the respective battery housing portions 42A and 42B. Specifically, the conductive plates 50 and 51 are connected to the corresponding battery housings 4.
2A and 42B are opposed to each other (see FIG. 1).
0), and when the batteries 8, 8 are stored in the battery storage portions 42A, 42B, the corresponding batteries 8, 8 are generated by the spring force.
Is always pressed against. In this case, the first conductive plate 50 is electrically connected (pressed) to the negative pole of the corresponding battery 8,
The second conductive plate 51 is electrically connected (pressed) to the positive electrode of the corresponding battery 8 (see FIG. 13). The switch plate 52 extends so as to sandwich the battery housing portions 42A and 42B between the pair of conductive plates 50 and 51.
Specifically, as clearly shown in FIG. 12, the switch plate 52 extends across the two battery housing portions 42A and 42B so as to be substantially orthogonal to the conductive plates 50 and 51. In this case, one end of the switch plate 52 is connected to the partition walls 44A, 44B forming the battery housing portions 42A, 42B.
Outside, is fastened to the wall portion of the support substrate 2 via the first support shaft 54, and the other end of the switch plate 52 is connected between the battery accommodating portions 42 A, 42 B via the second support shaft 55. Is fixed to the wall of the support substrate 2 located at the position shown in FIG. The specific shape of the switch plate 52 is shown in FIG. 15 (see also FIG. 12). As shown, the switch plate 52 includes:
A first support portion (one end portion) 52g supported by the first support shaft 54, and a first inclined portion 52b extending from the first support portion 52g and inclined away from the support substrate 2

The switch is kept in the OFF state, which is separated from the battery 8 by a predetermined distance. In addition, all portions of the switch plate 52 except the switch portion 52a extend inside the support substrate 2, and only the switch portion 52a slightly extends from the back surface of the support substrate 2 to the outside. Therefore, when, for example, a cup as a placement object (object to be decorated) is placed on the placement surface of the cover 10 in a state where the support substrate 2 is placed on a table, for example, the switch section 52a faces upwards against the spring force. 15A, the switch 52a is displaced upward so as to rotate about the support shaft 55 and is pressed against the battery 8 as shown by a two-dot chain line in FIG. . That is, the switch is turned ON, the batteries 8 are electrically connected (the electric circuit 18D is electrically closed), and the LED 6 emits light. In the present embodiment,

As described above, the coaster 1A of the present embodiment can obtain the same operation and effects as those of the first embodiment, and the switch 52a is installed on the back side of the coaster 1A. Regardless, the switch 52a can operate only by the weight of the object. Therefore, the switch 52a is stably turned ON / OFF.
It is turned off. Further, since the switch 52a is located at a position where it cannot be seen from the outside, the design is excellent.

In this embodiment, the cover 10 is subjected to a diffuse reflection process. When the diffuse reflection process is performed on the cover 10 as described above, the internal LED 6
Alternatively, the color of the resin of the LED 6 is not visible from the surface (outside) (it looks like a uniform and uniform surface).

This embodiment (the same applies to the first embodiment)
Then, two lithium primary batteries 8 are used in series, and L
A resistor 20 is provided in series with the ED 6. Moreover, the resistance 2
The resistance value of 0 is set to 5 times or more the internal resistance of the battery 8. Therefore, it is possible to keep the LED 6 turned on for a long time. Hereinafter, this will be described in detail.

FIG. 16 shows a conventional LED drive circuit. As shown in the figure, even in this conventional system in which only one battery 8 and one LED 6 are provided, the LED 6 is naturally turned on. Where the LED
A forward voltage (forward voltage drop) V _F 6 is a value as shown in FIG. 17, The battery 8 is a lithium primary battery LR2032 (3.0 V (average), 190 mAh) When a, FIG As shown in FIG. 16, the electromotive force E _i of the battery 8 is 3.0 V, the internal resistance R _i of the battery 8 is about 10Ω, and if the orange LED 6 is used, I
= (E _i −V _F ) / R _i = 100 mA will flow. Therefore, the LED 6 is actually turned on. Also, when using a blue LED 6 (when V _F the variation of the LED elements a combination of a lithium battery and what the new in 3.0 V) But if the initial voltage is about 3.2 V, I = (E _i− V _F ) / R _i = (3.2−3.0) / 1
A current of 0 = 20 mA flows, and it looks as if the lighting is good.

FIG. 18 shows the discharge characteristics of the lithium battery. It can be seen that the electromotive force decreases with a decrease in the remaining capacity, and that the larger the current at the time of discharge, the larger the voltage drop. When calculated based on this, the orange LED
6, 190 mAh / 100 mA = 1,9 hours (1.
Although the lighting time is about 9 hr), the usable voltage of the blue LED 6 is only 0.2 V, so that only 5% of the total capacity can be used.
Only r) lights up. Therefore, it cannot be established as a product.

Therefore, in the present embodiment, two lithium primary batteries 8 are used in series, and
0 is provided. Moreover, the resistance value of the resistor 20 is set to be at least five times the internal resistance of the battery 8. Specifically, a lithium primary battery (LR2032 (3 V (average), 190 m
Ah)) When 8 LEDs are used and the LED 6 is red and orange, the resistance of the resistor 20 is set to 150Ω.
When the LED 6 is green and blue, the resistance value of the resistor 20 is set to 240Ω. By doing so, in the case of the orange LED 6, I =
(E _i −V _F ) / R _i = (3.0 × 2-2.0) / 240
A current of $ 17 mA flows, and the lamp is turned on for about 11 hours. In the case of the blue LED 6, I = (E _i −
V _F ) / R _i = (3.0 × 2-3.6) / 150 ≒ 16 m
The current of A flows, and it lights for about 12 hours. FIG. 19 is a graph showing a comparison between the related art and the present embodiment (the present invention).

In this embodiment, a lithium (primary) battery has been described. However, as is well known, so-called dry batteries widely used today include NiCD (nickel) batteries, NiMH (nickel-metal hydride) batteries, and the like. , Manganese batteries, and lithium (secondary) batteries. As described above, the electromotive force of one unit cell of the lithium (primary) battery is 3.
Strictly speaking, for 0 V (average value, hereinafter the same for electromotive force), the electromotive force of one unit cell is lithium (secondary).
Battery is 3.7V, NiCD (NiCad) battery is 1.2
V, NiMH (nickel-metal hydride) battery is 1.3V, and manganese battery is 1.5V. Therefore, according to the present embodiment, when a lithium (secondary) battery is used, the same effect can be obtained by using two cells in series. However, a NiCD (NiCad) battery, a NiMH (NiMH) battery, and a manganese battery It can be seen that at least four cells are required in series.

As described above, according to the present embodiment, each L
The lighting time is improved by about one digit or more in the ED, and the commercialization of the coaster can be established for the first time by adopting the configuration of the present embodiment.

It is needless to say that the present invention is not limited to the above embodiment, but can be variously modified without departing from the gist of the present invention. That is, the mounting table of the present invention only needs to have the LED for emitting the decoration light, and the installation form of the LED and other structures are not limited to the above-described embodiment.
