  However, the coaster described in Patent Document 2 automatically changes the light of the light emitting diode element every predetermined time. In other words, the user cannot set the color of the light emitted from the light-emitting diode element, and cannot continue lighting the favorite color or select the color according to the atmosphere of the place.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coaster that allows a user to set the color of light emitted from a light-emitting diode element.

  In order to solve the above-mentioned problem, the coaster of the present invention is a coaster having RGB light emitting diode elements that irradiate color light toward the outside from a hole formed in the surface of a housing, and the light emitting diode elements Control means for changing the driving current of each of the light emitting diodes in a predetermined pattern, and switch means for setting the color of the irradiating light. The control means is adapted to output the light emitting diode element in accordance with an output signal of the switch means. Each of the drive currents is maintained in that state.

  The hole is formed in the center of the surface of the housing, and a non-slip mat is attached to at least a part of the portion excluding the hole on the surface of the housing.

  This coaster is a battery drive type, and is configured to use a touch switch as the switch means and also serve as a power switch.

  In the case of the coaster according to claim 1 of the present invention, the user can set the color of the irradiation light through the switch means, so that the user continues to turn on the favorite color or produces an effect that matches the atmosphere of the place. It becomes possible to do.

  In the case of the coaster according to claim 2 of the present invention, the light of the light emitting diode element disposed in the central portion of the casing is irradiated toward the substantially central portion of the beverage glass placed in the casing. Therefore, the beverage glass can be beautifully shined.

  In the case of the coaster according to claim 3 of the present invention, the slipper mat is attached to at least a part of the portion excluding the hole on the surface of the housing. There is no such thing as the glass slipping due to the water accumulated between.

  The coaster according to claim 4 of the present invention is convenient because the battery can be replaced from the bottom surface side of the housing.

  In the case of the coaster according to claim 5 of the present invention, since the touch switch is used as the switch means, the user can set the color of the irradiation light only by lightly touching the touch switch.

  In the case of the coaster according to claim 6 of the present invention, the switch means also serves as a power switch, which is advantageous in reducing the cost.

  Hereinafter, a coaster according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a coaster according to an embodiment of the present invention, FIG. 2 is a circuit diagram of the coaster, and FIG. 3 is a schematic sectional view showing a use state of the coaster.

  The coaster shown in FIG. 1 includes a housing 100 having a hole 112 formed in the center of the surface 110, and an RGB light emitting diode element 200 that emits color light from the hole 112 of the housing 100 toward the outside. , Switch means 300 for setting the irradiation light of the light emitting diode element 200, and control means 400 for controlling the lighting of the light emitting diode element 200 by changing the drive current of the light emitting diode element 200 in a predetermined pattern. ing. Hereinafter, each part will be described in detail.

  As shown in FIG. 2, the light emitting diode element 200 includes an R (Red) LED 210, a G (Gene) LED 220, and a B (Bule) LED 230.

  The casing 100 is a cylindrical molded product having a bottom opening 120 formed of ABS resin, and a substantially circular recess 111 for attaching a non-slip mat 600 to be described later is formed on the surface 110 of the casing 100. A hole 112 is formed at the center of the recess 111. A transparent acrylic plate 500 is attached to the hole 112. The light emitted from the light emitting diode element 200 is irradiated through the acrylic plate 500 toward the beverage glass X (see FIG. 3) placed on the housing 100. As a result, the glass X for drinks shines. The acrylic plate 500 also serves to prevent dust and the like from entering the housing 100.

  The housing 100 also has a bottom plate 130 that closes the bottom opening 120. A substrate (not shown) on which the light emitting diode element 200 is mounted is inserted into the housing 100 from the bottom opening 120 and installed. In addition, by removing the bottom plate 130, it is possible to replace the battery accommodated in the power supply unit provided on the substrate.

  The non-slip mat 600 is bonded to the recess 111 with an adhesive or the like. In the non-slip mat 600, the portion facing the hole 112 is made transparent, while the glass mounting surface of the other portion is a place for expressing the design. For example, printing processing of one or two colors is performed on the glass mounting surface. By attaching the non-slip mat 600, it is possible to prevent the beverage glass X (see FIG. 3) from slipping with water droplets and the like, and enjoy the design shown.

  The switch means 300 is a touch-type switch using human body resistance provided at an end portion of the upper surface 110 of the housing 100, and also serves as a power switch. The switch means 300 outputs as an output signal whether or not the user's finger has touched.

  Here, a one-chip microcomputer is used as the control means 400. The anodes of the R LED 210, the G LED 220, and the B LED 230 are connected to the power supply circuit via current limiting resistors (not shown), and the cathodes are connected to the I / O ports of the one-chip microcomputer. Further, the switch means 300 is connected to another I / O port.

  The memory of the one-chip microcomputer stores a plurality of data of change patterns of the magnitudes of the drive currents such as the R LEDs 210. Here, since the emission intensity of the R LED 210 and the like is controlled by duty control, the ratio of the on period in which the R LED 210 etc. is turned on and the off period in which it is turned off in one cycle (0.5 mS in this case). Data of a change pattern of a certain duty ratio is stored in the memory. That is, the duty ratio change pattern data on the memory is sequentially read, and the R LED 210 and the like are turned on / off according to this data, thereby controlling the magnitude of the drive current of the R LED 210 and the like. . The light emission pattern for turning on the R LED 210 and the like is set based on the output signal of the switch means 300. Here, each time the user's finger contacts the switch means 300, the light emission patterns 1, 2, 3, and extinguishing are set in this order.

  When the light emission pattern 1 is set, the light emitting diode element 200 is turned on, and the light emission color changes smoothly and repeatedly into red, green and blue. When the next light emission pattern 2 is set, the light emission color of the light emitting diode element 200 is sequentially switched to red, green and blue at intervals of about 2.4 seconds. When the next light emission pattern 3 is set, the light emission color and light emission intensity of the light emitting diode element 200 at the time of switching from the light emission pattern 2 are maintained. When the next turn-off is set, the light-emitting diode element 200 stops turning on.

  That is, in the light emitting pattern 1, the light emitting diode element 200 is switched from off to on, and the magnitude of the driving current is sequentially changed. In the light emitting pattern 2, the change pattern of the driving current of the light emitting diode element 200 is changed, In the light emitting pattern 3, the driving current of the light emitting diode element 200 is made constant, and when the light is turned off, the light emitting diode element 200 is switched from on to off.

  When the light emitting diode element 200 is turned on for 60 minutes or longer, the R LED 210, the G LED 220, and the B LED 230 blink in this order for about 5 seconds, and then the light emitting diode element 200 is automatically switched off. It is like that. This is to prevent the user from forgetting to erase. In this case, when the setting of the light emission pattern immediately before turning off is saved in a register in the one-chip microcomputer and lighting is resumed, the light emitting diode element 200 is turned on with the light emission pattern of the setting. Each time the user's finger contacts the switch means 300, the R LED 210, the G LED 220, and the B LED 230 are blinked twice in this order. This is to inform the user that the setting has been switched.

  In the case of the coaster configured as described above, the user can set a favorite color of the light emitting diode element 200 by touching the switch means 300. Therefore, the user can continue to turn on a favorite color or produce an effect in accordance with the atmosphere of the place.

  The coaster is a coaster having RGB light emitting diode elements that irradiate color light outward from holes formed on the surface of the housing, and each of the drive currents of the light emitting diode elements in a predetermined pattern. And a control means for changing the light intensity, and a switch means for setting the color of the irradiation light. The control means maintains the drive current of the light emitting diode element in the state in accordance with the output signal of the switch means. Any design changes can be made as long as they are designed to do so.

  Accordingly, the casing 100 is assumed to have the cylindrical shape of the bottom opening 120 made of ABS resin, but is not limited thereto, and may be, for example, a rectangular tube shape made of metal. Moreover, the hole 112 may be provided in a peripheral part, and you may make it provide the light emitting diode element 200 in the said peripheral part. Since attachment of the non-slip mat 600 is optional, in this case, the housing 100 does not need to be provided with the recess 111. Regarding the light emitting diode element 200, it is desirable that the three primary colors of RGB are aligned, but it is sufficient that at least two colors are provided. Any means may be used for the control means 400 as long as the above functions can be realized.

  Note that the light emission patterns 1 and 2 set in the control unit 400 have been described by way of example, and it goes without saying that the light emission time and the like can be arbitrarily set.

It is a disassembled perspective view of the coaster which concerns on embodiment of this invention. It is a circuit diagram of the coaster. It is typical sectional drawing which shows the use condition of the coaster.
