However, in the above-mentioned conventional lighting device, the doll merely shines, and it lacks in fun.
Therefore, it is an object of the present invention to provide a lighting device having an interestingness that has not been obtained in the past.

The present invention has been made to solve the above-described problems, and includes a motor, an operating mechanism that is operated by the motor, a base member on which the motor and the operating mechanism are arranged on the upper surface, the motor, and the A cover is attached to the base member so as to cover the operating mechanism, and an LED arranged inside the cover. The cover is formed of a soft material that is elastically deformable and transparent. A predetermined operation can be executed by the operating mechanism.

The present invention is as described above, the cover is formed of a soft material that is elastically deformable and has a light-transmitting property, and the LED is arranged inside the cover. With such a configuration, it is possible to enjoy by touching or holding the lighting device, and it is possible to make a unique impression that is soft to the eye. Further, since the operation mechanism can execute a predetermined operation, the lighting device can be more interesting.

The illumination device may be in the form of a doll, and the operating mechanism may swing the doll left and right. The swinging movement of the doll does not significantly impair the function as lighting, so that it is possible to achieve both the function as lighting and the fun of movement.

Alternatively, an electric wire connecting portion for supplying electric power may be provided on the back surface, and the electric wire connecting portion may be arranged on the swing shaft on which the actuating mechanism swings the doll. With such a configuration, since the electric wire is not pulled when the doll swings, it is possible to prevent the electric wire from being entangled and the doll from falling.

In addition, a white outer shell that covers the operating mechanism may be provided inside the cover, and the LEDs may be arranged around the outer shell. With such a configuration, the shadow of the operating mechanism is unlikely to occur when the LED is turned on. That is, since the actuating mechanism is covered with the outer shell, the rugged actuating mechanism is less likely to be shaded. In addition, since the LEDs are arranged around the outer shell, the periphery of the outer shell is uniformly illuminated, and the shadow of the outer shell itself is unlikely to occur. Moreover, since the white outer shell reflects the light of the LED, the light is diffused and the shadow is less likely to occur. Therefore, it is possible to provide a soft impression of the illumination although it has a built-in mechanical structure.

The base member 12 is of a bowl shape having an upper opening, and a motor 15 and an operating mechanism 20 described later are arranged therein (however, as will be described later, vertical movement which is a part of the operating mechanism 20). The member 26 penetrates the base member 12 and projects below the base member 12). Further, the bottom surface of the base member 12 is provided with a hole for allowing a lower portion of a vertically moving member 26, which will be described later, to project to the outside.

The main board 13 is for controlling the operation of the lighting device 10. A CPU, a ROM, a RAM and the like are mounted on the main board 13 to control driving of the motor 15 and lighting of the LEDs 13a. A plurality of LEDs 13a are mounted on the upper surface of the main board 13 as shown in FIG. The main board 13 is horizontally arranged on the base member 12. Although the LED 13a is mounted on the upper surface of the main board 13 in the present embodiment, the invention is not limited to this, and the LED 13a may be provided separately from the main board 13.

The sub-board 14 is a board for disposing the LEDs 13 a at a position apart from the main board 13. A plurality of LEDs 13a are arranged on the sub-board 14 as shown in FIG. The sub-board 14 is controlled by the main board 13, that is, the lighting of the LEDs 13 a mounted on the sub-board 14 is controlled by the main board 13. The sub-board 14 is horizontally fixed on an outer shell 29 described later.

The motor 15 serves as a power source for operating the operation mechanism 20 described later. As shown in FIG. 4B, an output gear 15a is attached to the output shaft of the motor 15, and the rotational force of the motor 15 is transmitted to the operating mechanism 20 via the output gear 15a. Has become.

The operating mechanism 20 is operated by the motor 15 to perform a predetermined operation. The actuating mechanism 20 according to the present embodiment performs an operation of swinging a doll, which is the appearance of the lighting device 10, to the left and right. As shown in FIG. 4, the operating mechanism 20 includes a gear group 21, a rotating shaft 22, a cam member 23, a cylinder 25, a vertical movement member 26, and a biasing member 27.

The gear group 21 is for transmitting the rotational force of the motor 15, and is composed of a plurality of gears that mesh with each other. The gear on the most upstream side of the gear group 21 meshes with the output gear 15a of the motor 15, and is adapted to rotate simultaneously when the motor 15 rotates.

The rotating shaft 22 is rotatably supported by the base portion 11 and is configured to rotate integrally with a gear on the downstream side of the gear group 21. The rotary shaft 22 is arranged so as to be horizontal when the base 11 is placed horizontally, and the cam members 23 are fixed to both ends thereof.

The cam member 23 is a member that is fixed to the rotating shaft 22 and rotates integrally with the rotating shaft 22. The cam member 23 is an egg-shaped disc cam having a circumferential surface whose distance from the center is not constant. The cam members 23 are attached to both ends of the rotary shaft 22 in different directions. Below the two cam members 23 at both ends, one vertical movement member 26 is arranged corresponding to each cam member 23.

The cylinder 25 is a cylindrical member for guiding the sliding movement of the vertical movement member 26. Two of the cylinders 25 are arranged corresponding to the two vertically moving members 26. The vertical movement member 26 is supported by the cylinder 25 so as to be vertically slidable.

The vertical movement member 26 has an upper surface in contact with the peripheral surface of the cam member 23, and is adapted to move up and down following the rotation of the cam member 23. The vertical movement member 26 is constantly urged upward by the urging member 27, whereby the upper surface of the vertical movement member 26 is pressed against the peripheral surface (lower end portion) of the cam member 23. Two vertical moving members 26 are provided on the left and right corresponding to the cam member 23, and the two vertical moving members 26 are alternately moved up and down. That is, since the peripheral surfaces of the two cam members 23 are arranged so as to project in mutually opposite directions, when one of the vertical movement members 26 reaches the top dead center, the other vertical movement member 26 becomes the bottom dead center. It is configured to come to.

The gear group 21 and the cam member 23 described above are arranged above the main board 13 as shown in FIG. The vertical movement member 26 vertically penetrates the main board 13 and the base member 12. A ground contact portion 26 a is provided at the lower end of the vertical movement member 26 that penetrates the base member 12. The grounding portion 26a is designed to ground when the lighting device 10 is placed on the ground. When the up-and-down moving member 26 moves upward, as shown in FIG. 5, the grounding portion 26a pushes the ground to lift the lighting device 10. Then, the left and right vertical movement members 26 alternately push the ground, so that the lighting device 10 swings left and right.

The outer shell 29 is a member that covers the upper surface of the actuating mechanism 20 inside a cover 30 described later, and is a dome-shaped white member as shown in FIG. The outer shell body 29 according to the present embodiment covers all the portions protruding above the main substrate 13. The outer shell 29 is fixed to the base portion 11 (main board 13 in the present embodiment) so as not to cover the LEDs 13 a mounted on the main board 13. As a result, the LEDs 13a are arranged around the outer shell 29.

The cover 30 is a member attached to the base member 12 so as to cover the motor 15 and the operating mechanism 20 from the outer side of the outer shell body 29. The base member 12 is formed of a flexible material that is elastically deformable and has a light-transmitting property (for example, a synthetic resin such as a silicone resin). The cover 30 has a shape in which the opening is expanded so as to completely cover the outer shell body 29, and by attaching the cover 30 to the base member 12, a doll form as shown in FIG. 1 is obtained. The opening of the cover 30 and the opening of the base member 12 are formed to have the same size, and the cover 30 can be attached to the base member 12 by joining the two openings via the intermediate member 31. In the present embodiment, the cover 30 is fixed to the upper surface of the intermediate member 31 with screws or the like, and the base member 12 is fixed to the lower surface of the intermediate member 31 with screws or the like.

By mounting the cover 30 in this manner, the LEDs 13a are provided inside the cover 30. The LEDs 13a are arranged around the outer shell body 29 and on the upper surface of the outer shell body 29, and emit light upward.

The operation of the lighting device 10 is controlled by the main board 13 described above. The main board 13 is mainly composed of a CPU, and the CPU reads various programs stored in the ROM to control various input devices and output devices.

As the input device connected to the main board 13, as shown in FIG. 6, a main switch 41, a vibration sensor 42, and a sound sensor 43 are provided. Further, as an output device connected to the main board 13, as shown in FIG. 6, an LED 13a, a motor 15, and a speaker 46 are provided. Note that the input/output device is not limited to these, and may include other input devices.

The main switch 41 is for turning on/off the main power supply of the lighting device 10. The main switch 41 is a push button switch that alternately switches on and off of the main power source each time the main switch 41 is pressed. When the main switch 41 is pressed to turn on the main power supply, electric power is supplied to the main board 13 and the lighting device 10 can be operated. When the main switch 41 is pressed to turn off the main power supply, the power supply to the main board 13 is cut off and the lighting device 10 cannot operate. Although not particularly shown, the main switch 41 may be arranged inside the base member 12 so that the main switch 41 can be pressed from the outside of the base member 12. Since the base member 12 is formed of a flexible material, even when the base member 12 is pressed from the outside, the base member 12 is deformed and the main switch 41 can be pressed. According to this structure, since the switch is not exposed to the outside, the appearance as a doll is not impaired and a soft impression can be maintained.

The vibration sensor 42 is for detecting the vibration applied to the lighting device 10. The vibration sensor 42 detects, for example, a vibration of the head of a doll constituting the lighting device 10 that is tapped, and outputs a signal to the main board 13. The main board 13 performs various operations based on the signal output from the vibration sensor 42.

The sound sensor 43 is for detecting a sound generated around the lighting device 10. The vibration sensor 42 detects, for example, that a voice is uttered toward the lighting device 10, and outputs a signal to the main board 13. The main board 13 performs various operations based on the signal output from the sound sensor 43.
Various modes are conceivable as the operation performed when the main board 13 receives a signal from the vibration sensor 42 or the sound sensor 43.

For example, the brightness of the LED 13a may be switched each time the lighting device 10 is tapped to adjust the brightness. Specifically, each time the vibration sensor 42 detects a vibration, the brightness of the LED 13a may be cycled and switched in the order of “dark”→“medium”→“bright”→“off”. .. Note that "dark" is the darkest state, "medium" is the state of intermediate brightness, "bright" is the brightest state, and "off" is the off state.

In addition, the lighting mode (mode) of the LED 13a may be switched each time the lighting device 10 is tapped. Specifically, every time the vibration sensor 42 detects a vibration, the vibration sensor 42 circulates and switches in the order of “always-on mode”→“step change mode”→“stepless change mode”→“flashing mode”. May be. The "always-on mode" is a mode in which the LED 13a is always lit, the "step change mode" is a mode in which the brightness of the LED 13a is switched at regular intervals (for example, 2 seconds), and the "stepless change mode" is the LED 13a. Is a mode in which the brightness of the variable changes continuously (a mode in which the brightness is as if breathing), and the "blinking mode" is a mode in which the LED 13a blinks.

Alternatively, the actuating mechanism 20 may be actuated by talking to the lighting device 10 to perform a predetermined operation. Specifically, when the sound sensor 43 detects a sound, the main board 13 may rotate the motor 15 to operate the actuating mechanism 20 so that the lighting device 10 swings left and right.
Further, in accordance with the above-described operation, the speaker 46 may output sound.

The lighting device 10 according to the present embodiment is operated by an external power source, and has a wire connection portion 32 for supplying power on the back surface. A power cable connected to a household power source can be connected to the electric wire connecting portion 32 (the power cable may be always connected to the electric wire connecting portion 32, or the electric wire connecting portion 32 may be connected to the electric wire connecting portion 32). It may be removable). As shown in FIG. 5, the wire connecting portion 32 is arranged on a swing shaft on which the operating mechanism 20 swings the doll. For this reason, the position of the electric wire connecting portion 32 does not change greatly when the doll swings. With such a configuration, since the electric wire is not pulled when the doll swings, it is possible to prevent the electric wire from being entangled and the doll from falling.

Although the lighting device 10 according to the present embodiment is operated by an external power source, the present invention is not limited to this. The lighting device 10 may be operated by a built-in battery.

As described above, according to the present embodiment, the cover 30 is formed of a soft material that is elastically deformable and translucent, and the LED 13a is arranged inside the cover 30. Therefore, the lighting device 10 can be enjoyed by touching or holding it, and a unique impression that is soft to the eye can be obtained. Further, since the operation mechanism 20 can execute a predetermined operation, the lighting device 10 can be made even more interesting.

Further, the illumination device 10 is in the form of a doll, and the operating mechanism 20 swings the doll to the left and right. Since the swinging movement of the doll does not significantly impair the function as lighting, it is possible to achieve both the function as lighting and the fun of movement.

Further, a white outer shell body 29 that covers the operating mechanism 20 is provided inside the cover 30, and the LEDs 13 a are arranged around the outer shell body 29. Therefore, when the LED 13a is turned on, a shadow of the operating mechanism 20 is unlikely to occur. That is, since the actuating mechanism 20 is covered with the outer shell 29, a rugged shadow of the actuating mechanism 20 is unlikely to occur. Further, since the LEDs 13a are arranged around the outer shell body 29, the outer shell body 29 is uniformly illuminated, and the outer shell body 29 itself is less likely to be shaded. In addition, since the white outer shell 29 reflects the light of the LED 13a, the light is diffused and the shadow is unlikely to occur. Therefore, it is possible to provide a soft impression of the illumination although it has a built-in mechanical structure.

It is also easy to produce lighting for another animal or character simply by changing the shape of the cover 30. Therefore, since variations can be developed without changing the internal structure, manufacturing cost and inventory can be suppressed.
