[0009] The following embodiments will be described in detail with reference to the accompanying drawings. The following embodiments do not limit the scope of the claimed invention, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined arbitrarily. Identical or similar components are designated by the same reference numerals, and redundant descriptions will be omitted. In each figure, the up, down, left, and right directions relative to the paper surface will be used in the description of the present embodiment as the up, down, left, and right directions of components (or parts) in the present embodiment.
[0010] First, a circuit diagram of the light-emitting circuit that constitutes the light-emitting performance unit corresponding to this embodiment is shown in Figure 1. The light-emitting circuit can be constructed by arranging light-emitting elements such as LEDs of multiple colors on the wiring of a flexible printed circuit board (FPC). By arranging the light-emitting elements on the flexible printed circuit board in any part of a model or doll toy (hereinafter collectively referred to as a model), it is possible to light up a specific part of the model.
[0011] The circuit diagram shown in Figure 1 is a simplified illustration of the light-emitting circuit. The number of light-emitting elements is limited for illustrative purposes only, but a larger number of light-emitting elements can be arranged on the flexible printed circuit board.
[0012] 1, the light-emitting circuit 10 is configured to include a power supply 100, a current direction control circuit 110, a control unit 120, and a light-emitting unit 130. The power supply 100 supplies power for operating the light-emitting circuit 10. The current direction control circuit 110 is a switching circuit that switches the direction of current flowing through the light-emitting unit 130 between a first direction and a second direction opposite to the first direction, and operates in response to a control signal from the control unit 120. The control unit 120 supplies a control signal for controlling the operation of the current direction control circuit 110. The control unit 120 can be configured with a microcomputer, and switches the control signal supplied to the current direction control circuit 110 so that the direction of current flow switches between the first direction and the second direction at regular time intervals, for example.
[0013] The light emitting unit 130 is composed of two LEDs of different colors, with a first LED of a pair whose forward direction is a first direction and a second LED of a pair whose forward direction is a second direction, arranged in parallel. In other words, in the light emitting unit 130, the first LED and the second LED are connected in parallel with their polarities reversed. The first LED and the second LED have different light emission colors; for example, if the first LED is red, the second LED can be green.
[0014] The color combinations are not limited to those described above, and any color combination can be used. Also, the colors may be combined differently depending on the body part. For example, the arms and legs of the model may be a combination of red and green, and the torso and head may be a combination of red and blue. Also, some of the light-emitting body units 130 may be a combination of LEDs of the same color. In this case, the light emission color will not change in some body parts. For example, the light emission color may be maintained constant in the head of the model.
[0015] Furthermore, a plurality of light emitting units 130 are connected in series, so that one current direction control circuit 110 can control the light emission of the light emitting units 130 for the entire model.
[0016] The input unit 140 is, for example, an operation input unit such as a switch or button provided on the model, and the control unit 120 may switch the light emission mode of the light emitter unit 130 according to the input from the input unit 140.
[0017] 2 is a diagram showing an example of the configuration of a flexible printed circuit board, which is a component of a light-emitting performance unit corresponding to this embodiment. Wiring 201 runs through the flexible printed circuit board 200, and the wiring 201 is covered with a base film and a coverlay. A light-emitting unit 130 is installed at an arbitrary position on the wiring 201. In the example shown in FIG. 2, the wiring 201 as a whole forms a single wire, and a current direction control circuit 110 is connected to a positive terminal 202 and a negative terminal 203, so that the direction of the current flowing through the wiring 201 can be switched between a first direction and a second direction.
[0018] The light-emitting unit 130 is disposed on the front surface side of the flexible printed circuit board 200, and wiring 201 is connected to the LED of the light-emitting unit 130. For example, as shown in the area surrounded by the dotted line, the anode of the red LED and the cathode of the green LED are connected to the positive electrode side of the wiring 201, and the cathode of the red LED and the anode of the green LED are connected to the negative electrode side.
[0019] The flexible printed circuit board 200 is provided with engagement holes 204 for fixing to parts of the model, and the position of the flexible printed circuit board 200 can be fixed by connecting parts through the engagement holes 204. In addition, the flexible printed circuit board 200 can be bent as desired, so it can be attached by bending or flexing it to fit the shape of parts of a toy doll or model.
[0020] 2, the flexible printed circuit board 200 is divided into limbs, shoulders and arms, and torso and waist, as shown by the dashed lines. The flexible printed circuit board 200 connects the torso and waist with the shoulders and arms, and also connects the torso and waist with the limbs (legs). As a result, the flexible printed circuit board 200 is arranged from the torso and waist across the arms via the shoulders, and from the torso and waist across the limbs.
[0021] The flexible printed circuit board 200 is disposed to penetrate or pass through the interior of parts that constitute joints, such as the neck, shoulders, elbows, waist, and knees. Therefore, it is desirable for the width of the flexible printed circuit board 200 to be as narrow as possible, and it is necessary to reduce the number of wires. In this embodiment, the number of wires on the flexible printed circuit board 200 can be reduced to two, allowing the flexible printed circuit board 200 to be configured with a minimum number of wires. As an example, the width of the wire portion of the flexible printed circuit board is, for example, 4 mm at its narrowest point. However, the narrowest width of the wire portion varies depending on the size of the model or doll toy, and may be wider than 4 mm or narrower than 4 mm. However, it is desirable for the width of each wire to be 1 mm and for the width between each wire to be 0.3 to 0.5 mm to suppress noise.
[0022] Next, with reference to Fig. 3, the light emission control of the light emitter unit 130 by the control unit 120 will be described. The control unit 120 can perform PWM (Pulse Width Modulation) control of the voltage supplied to the light emitter unit 130 via a current direction control circuit. Fig. 3 shows an example of control, with the vertical axis of the graph indicating the brightness of the LEDs as the ratio (unit: %) of the voltage pulse that is on per unit time in terms of the duty ratio. For both the red LED and the green LED, the duty ratio is increased from 0% to 90% over the first approximately 3 seconds, thereby increasing the brightness from the off state.
[0023] After that, when the duty ratio reaches 90%, it is dropped to 50% over the course of about 3 seconds, reducing the brightness. After that, it cycles from 50% to 90% four times in cycles of about 6 seconds, and the brightness is increased or decreased accordingly. At the end of the performance, it drops from 50% to 0% in the final 3 seconds, gradually reducing the brightness and turning off the lights. The red and green LEDs are lit alternately, and the above control is repeated. The interval between switching between the red and green LEDs can be about 10 seconds, for example, but it can also be shorter or longer.
[0024] The above control method is merely an example, and other methods may be used to control the duty ratio and the lighting time. Alternatively, the red LED or the green LED may be switched on and off depending on an operation input from the input unit 140. Alternatively, the input unit 140 may be provided with a plurality of buttons, and the light emitter unit 130 may be caused to emit light with different duty ratios or lighting times depending on the type of button operated. Alternatively, the switch of the input unit 140 may be located, for example, at a joint, and may be turned on by moving the joint. For example, the switch may be turned on when the arm located at the arm joint is raised.
[0025] The model may also be configured to be manually or automatically transformable from a first state to a second state, with the light-emitting body unit 130 hidden in the first state and the light-emitting body unit 130 exposed in the second state. In this case, in the first state, some or all of the parts covering the light-emitting body unit 130 may be made of a light-blocking material. The light-blocking material may be configured, for example, by using molded parts in a light-absorbing color or by attaching a reflective sticker.
[0026] In this embodiment, the flexible printed circuit board 200 is arranged inside the model, specifically across the torso and arms, and passing through joints (for example, elbow joints and knee joints). This allows the light-emitting unit 130 arranged on the flexible printed circuit board 200 to be arranged at a predetermined position on the model. Specific examples of arrangement will be described below with reference to FIGS. 4 to 6.
[0027] FIG. 4 shows an example in which the flexible printed circuit board is placed on the torso and waist of a model. Part 401 of the flexible printed circuit board is placed inside clear part 402, and light emitted from the LEDs on both ends passes through clear part 402 and is emitted to the outside. Clear part 402 is a transparent ABS resin member of a predetermined color, which allows light to pass through. Part 403 is placed on top of clear part 402, and part 403 is made of polystyrene, which does not allow light to pass through. However, materials other than polystyrene (thermoplastic resins such as polyethylene and ABS, thermosetting resins, metals, etc.) can be used to form such opaque parts. Therefore, light emitted from the LEDs placed on part 401 is emitted downward in the figure. Wiring portion 404 of the flexible printed circuit board extends through an opening in part 405 to other parts of the model. In this way, the wiring of flexible printed circuit board 200 passes through the parts of the model and is placed within the model (e.g., limbs).
[0028] Part 406 is a connector for connecting flexible printed circuit board 200 to external devices and power supply parts. It can be used to connect current direction control circuit 110, power supply 100, control unit 120, input unit 140, and the like shown in FIG. 1 . In this embodiment, current direction control circuit 110, power supply 100, control unit 120, and input unit 140 are arranged as a battery box within a base on which the model is installed and are connected to connectors via predetermined wiring. However, this embodiment is merely an example, and the current direction control circuit 110, power supply 100, control unit 120, and input unit 140 may all be mounted inside the model. Alternatively, at least some of them, such as only the current direction control circuit 110, the current direction control circuit 110, the control unit 120, and the input unit 140, may be mounted, and the remaining parts may be mounted within the installation base.
[0029] Next, Figure 5 shows an example of the configuration of the model's legs. Part 501, on which LEDs from a flexible printed circuit board are arranged, is placed inside surface-emitting part 502. The surface-emitting part is made of GP (high-impact PS) and has a milky white color. While the above-mentioned clear part 402 is made of a see-through transparent color, the surface-emitting part is intentionally made milky white like frosted glass, or semi-transparent to prevent light from escaping and diffuse the light so that the entire light-emitting surface shines evenly.
[0030] A light-shielding part 503 that does not transmit light is arranged on the outside of the surface-emitting part 502, and is configured in combination with other parts so that the position of the light-shielding part 503 can be shifted so that the surface-emitting part 502 is partially exposed from a state in which the surface-emitting part 502 is hidden by the light-shielding part 503. The mechanism for shifting the position of the light-shielding part 503 is a common mechanism, so a description thereof will be omitted. As a result, light generated by lighting the LED can be seen through the gap in the light-shielding part 503, via the surface-emitting part 502.
[0031] Although the above describes a case where light from an LED is directly received by a surface-emitting part, the light may also be diffused by the surface-emitting part via a clear part, as shown in the exemplary cross-sectional view of Fig. 6. In Fig. 6, light emitted from an LED 601 is transmitted to and diffused by a surface-emitting part 605 via clear parts 602 and 603. Because the outside of the clear part is covered by a light-shielding part 604 that does not transmit light, the light is not diffused in the left-right direction but is transmitted in the direction of part 605. By using a clear part in this way, the direction and range of light diffusion can be adjusted depending on the size and thickness of the clear part, and also by combining it with a light-shielding part.
[0032] As described above, according to this embodiment, it is possible to alternately or selectively light up multiple LEDs of different colors by controlling the direction of current flowing through the wiring. In the illustrated embodiment, when current flows in a first direction, the red LED emits light, and when current flows in a second direction opposite to the first direction, the green LED emits light.
[0033] In this embodiment, the number of wirings can be minimized by connecting LEDs of different luminous colors in parallel in opposite directions, which also minimizes the width of the flexible printed circuit board and allows LEDs to be placed anywhere inside the model parts, allowing for light effects.
[0034] In addition, in this embodiment, by combining a light-emitting body (LED) that serves as the light source, a transparent part that transmits light, and a surface-emitting part that diffuses light, it is possible to transmit and diffuse light from the light source to any position on the model.
[0035] The invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention.
