(2) Details (2.1) Circuit composition The circuit configuration of the load control device 1 will be described with reference to FIG. 5.

The load control device 1 of the present embodiment is used, for example, to control the on/off of the load 200 of the lighting load.

The main body portion 2 includes a semiconductor switch 61, a light receiving portion 62, an operation detecting portion 63, a light emitting portion 64, a main body side control portion 65, and connection terminals 661 and 662. The main body part 2 of this embodiment includes: a switch main body 4 (fixed part), which is fixed to the construction surface; and a handle 5 (movable part), which is mounted on the switch main body 4 in a state that can be operated in response to user operations (see figure) 1～Figure 3). The semiconductor switch 61, the light receiving unit 62, the operation detecting unit 63, the light emitting unit 64, the main body side control unit 65, and the connection terminals 661 and 662 are housed in the switch main body 4.

Between the connection terminal 661 and the connection terminal 662, for example, an AC power supply 300 such as a commercial power supply and a load 200 such as a lighting load are connected in series.

The semiconductor switch 61 includes, for example, two switching elements 611 and 612 composed of an enhanced n-channel MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor; metal oxide semiconductor field effect transistor). Among the switching elements 611 and 612, the gates and the sources are connected to each other, the drain of the switching element 611 is connected to the connection terminal 661, and the drain of the switching element 612 is connected to the connection terminal 662.

The light receiving unit 62 includes a light receiving element 621 such as a photodiode that receives infrared rays (see FIGS. 1, 7A, and 7B). The light receiving unit 62 receives a control signal transmitted by the transmitter 3 using an optical signal (wireless signal) such as infrared rays. That is, the light receiving unit 62 of this embodiment performs wireless communication with the transmitter 3 using light as a medium.

The operation detecting unit 63 includes, for example, a push button switch that performs a momentary operation. The switch body 4 is provided with a T-shaped movable rod 44 (refer to FIG. 1) at a position corresponding to the protrusion 52 on the back of the handle 5 (refer to FIG. 3). One end of the movable rod 44 is movable in the front-rear direction, and the push button switch provided in the operation detection unit 63 is arranged on the back side of the movable rod 44. When the handle 5 is pushed by the user, the protrusion 52 of the handle 5 pushes the movable rod 44 backward, and the back of the movable rod 44 is used to push the button switch, so the contact state of the button switch changes. For example, if the contact state of the button switch is disconnected when the handle 5 is not pushed, then when the user pushes the handle 5 and pushes the movable rod 44 with the protrusion 52 of the handle 5, the button switch The contact state changes from the open state to the on state. Thereby, the operation detecting unit 63 can detect the operation of the handle 5 performed by the user, and output an operation signal corresponding to the operation of the handle 5 to the main body side control unit 65.

The light emitting section 64 includes, for example, a light emitting diode that emits green light. The front surface of the switch body 4 is provided with a display portion 47. The display unit 47 is composed of a light-transmitting lens that outputs the light emitted by the light-emitting unit 64 to the outside. The display portion 47 is located on the front surface of the switch body 4 in front of the light-emitting portion 64 housed inside the switch body 4, and the light emitted by the light-emitting portion 64 is output to the outside of the switch body 4 via the display portion 47.

The main body-side control unit 65 is configured using, for example, a microcomputer having a processor and a memory. That is, the main body side control unit 65 is realized by a computer system with a processor and a memory. Furthermore, the processor executes a suitable program, so that the computer system functions as the main body side control unit 65. Programs can be pre-recorded in memory, or provided via telecommunication lines such as the Internet or stored in non-temporary recording media such as memory cards.

The main body-side control unit 65 controls the on/off of the semiconductor switch 61 in response to the control signal received by the light receiving unit 62 or the operation signal input from the operation detecting unit 63 to turn on or off the load 200. The main body side control unit 65 can perform phase control by controlling the on/off of the semiconductor switch 61 to dim the load 200.

In addition, the main body-side control unit 65 controls the light-emitting unit 64 to turn on/off, thereby controlling the display content of the light-emitting unit 64 (display unit 47). For example, the main body control unit 65 turns on the light emitting portion 64 when the load 200 is turned off, and turns off the light emitting portion 64 when the load 200 is turned on. Since the light emitting part 64 is turned on when the load 200 is extinguished, the user can also grasp the position of the load control device 1 by the light of the light emitting part 64 (display part 47) when the surrounding is dark. In addition, the main body-side control unit 65 can also blink the light-emitting unit 64 when, for example, a timer operation (an action to light the load 200 for a fixed time) is performed, and the user can use the blinking of the light-emitting unit 64 (display unit 47) The operating state of the load control device 1 is grasped by the state.

The transmitter 3 includes a transmitter-side light-emitting unit 71, an operation acceptance unit 72, and a transmitter-side control unit 73.

The transmitter-side light-emitting unit 71 includes a light-emitting element such as a light-emitting diode that emits infrared light. The transmitter-side light-emitting section 71 emits light (outputs) an optical signal (wireless signal) such as infrared rays, and thereby transmits a control signal composed of the optical signal to the main body 2. That is, the transmitter-side light-emitting unit 71 of this embodiment performs wireless communication with the main body 2 using light as a medium.

The operation accepting unit 72 accepts operations performed by the user. The operation accepting unit 72 includes plural (for example, five) switches. The rear surface of the transmitter 3 is provided with five operating parts 331 (refer to FIG. 3) corresponding to the five switches and turning on the corresponding switches. The five operation parts 331 are, for example, a light-on/off switch key button, a light dimming key button, a light dimming key button, a dimming light key button, a timer light key button, and the like. The dimming button is a button that is operated in order to brighten the brightness when the load 200 is lit. The dimming button is a button that is operated to darken the brightness when the load 200 is lit. The dimming and lighting button is a button that is operated in order to lighten the load 200 with a preset dimming level. The timer lighting button is a button operated in order to perform a timer lighting action in which the load 200 is turned on for a fixed time and then turned off.

The transmitter-side control unit 73 is configured by, for example, a microcomputer having a processor and a memory. That is, the transmitter-side control unit 73 is implemented by a computer system with a processor and a memory. Furthermore, the processor executes an appropriate program, so that the computer system functions as the transmitter-side control unit 73. The program can be pre-recorded in the memory, and can also be provided via telecommunication lines such as the Internet, or recorded on a non-temporary recording medium such as a memory card.

The transmitter-side control unit 73, when the operation accepting unit 72 accepts the operation of the operation unit 331 performed by the user, sends a control signal corresponding to the operation content from the transmitter-side light emitting unit 71 to transmit it as a wireless signal. That is, the transmitter 3 has an operation part 331 provided on the rear surface of the transmitter 3, and the transmitter-side light-emitting part 71 emits light in response to the operation input of the operation part 331, thereby using the light signal to transmit control signals. Therefore, the operation unit 331 can be operated, and the light-emitting unit 71 on the transmitter side sends a signal corresponding to the operation input of the operation unit 331 to the light receiving unit 62.

(2.2) Structure Next, the structure and operation of each part of the load control device 1 will be described.

(2.2.1) Main body The main body 2 includes a switch main body 4 (fixed portion), including a light receiving portion 62, and a handle 5 (movable portion), and is mounted on the switch main body in a state that can be operated in response to a user's operation.

The switch body 4 includes a box-shaped container 41. The body 41 has a body 42 on the rear side and a cover 43 on the front side. The body 42 and the cover 43 are respectively formed of synthetic resin molded products. The body 41 is formed by combining the body 42 and the cover 43.

In order for the cover 43 to be detachably mounted to the mounting frame 8, a pair of mounting claws 45 are provided on the upper and lower sides of the left side, and a pair of mounting claws 45 are provided at the center in the vertical direction of the right side. , The aforementioned installation frame is used when the embedded wiring appliance is fixed to the construction surface. Thereby, by inserting the mounting claw 45 into the mounting hole 81 of the mounting frame 8, the switch body 4 can be mounted to the mounting frame 8, and the mounting frame 8 can be used to fix the switch body 4 to a construction surface 100 such as a wall surface ( Refer to Figure 4). Furthermore, a plate 9 is mounted on the front surface of the mounting frame 8, and the front surface of the load control device 1 (for example, the front surface of the handle 5 or the transmitter 3) is exposed from the opening 91 of the plate 9.

The front surface of the cover 43 is provided with the above-mentioned movable rod 44 at a portion on the right side of the center portion in the vertical direction. The front surface of the cover 43 is provided with a penetrating portion on the right side of the movable rod 44, and a display portion 47 is arranged in the penetrating portion. The display portion 47 is a light-transmitting lens formed of a transparent synthetic resin (for example, acrylic resin). The shape of the front surface of the display portion 47 is an ellipse that is long in the vertical direction. In addition, the display part 47 only needs to have translucency, and may be a translucent member or a dyed translucent member. In addition, the display part 47 is not limited to a synthetic resin product, and may be formed using glass or the like.

The front surface of the cover 43 is provided at the left end of the central part in the vertical direction with a shaft part 46 that supports the handle 5 in a rotatable state. The upper and lower parts of the front surface of the cover 43 are integrated with the cover 43 and provided with spring pieces 48 for pressing the handle 5 forward.

The front surface of the cover 43 is provided with a through hole 49 on the lower side of the shaft portion 46. The through hole 49 penetrates the front wall of the cover 43 in the front-rear direction. Inside the body 41, the light receiving element 621 of the light receiving portion 62 is arranged so as to face the through hole 49. Furthermore, the front surface of the cover 43 is provided with a cylindrical rib 491 that surrounds the light receiving element 621 of the light receiving section 62 at the edge of the through hole 49. The rib 491, in the cover 43 (fixed portion), is provided on a plane intersecting the incident direction D1 (see FIG. 7A) of the light signal incident on the light receiving section 62, and is specifically provided on a plane intersecting the incident direction D1 ( Front-to-back direction) a plane (front surface) that intersects in an orthogonal manner. In this embodiment, the through hole 49 is a round hole, and the rib 491 is cylindrical. The front surface of the cover 43 is provided with a cylindrical rib 491. Therefore, compared with the case without the rib 491, the leakage distance between the outside of the cover 43 and the light receiving element 621 becomes longer, which has an improved insulation advantage.

The handle 5 includes a handle body 50 and a light receiving cover 54.

The handle body 50 is a synthetic resin molded product, and the front view shape of the handle body 50 is rectangular. The back of the left side of the handle body 50 is provided with a bearing 51 (refer to FIG. 3) that supports the shaft 46 in a rotatable state. The back surface of the handle body 50 is provided with a protrusion 52 at a portion facing the movable rod 44.

When the handle body 50 is mounted to the body 41, the handle body 50 (that is, the handle 5) can rotate around the shaft 46. When the user pushes the end portion of the handle body 50 on the opposite side (right side) from the side supported by the shaft portion 46, the handle body 50 rotates around the shaft portion 46. When the protrusion 52 of the handle body 50 pushes the movable rod 44 due to the rotation of the handle body 50, the on/off of the button switch built in the body 41 changes. After that, when the user's hand moves away from the handle body 50 and the force of pushing the handle body 50 disappears, the handle body 50 receives the elastic force of the spring piece 48 and moves forward. Thereby, the movable rod 44 returns to the original position, and the on/off of the button switch built in the body 41 changes.

At the left end of the front surface of the handle body 50, a base-shaped mounting portion 53 protruding forward is integrally provided with the handle body 50. The mounting portion 53 is provided with a through hole 532 (see FIG. 1) that penetrates the mounting portion 53 in the front-rear direction at a location corresponding to the through hole 49 of the cover 43. Since at least a part of the rib 491 provided in the switch body 4 is inserted into the through hole 532, the possibility of interference between the rib 491 and the mounting portion 53 is reduced.

The light receiving cover 54 is formed of synthetic resin having translucency for infrared light. The light receiving cover 54 has a strip shape elongated in the vertical direction, and is attached to the front surface side of the placing portion 53. The light-receiving cover 54 is mounted on the front side of the mounting portion 53 so that the through hole 532 is covered by the light-receiving cover 54. The light-receiving cover 54 has a lens 541 (refer to FIG. 6) at a location on the side of the placing portion 53. The lens 541 is provided in a predetermined range covering a portion on the side of the mounting portion 53 of the light receiving cover 54 and a portion corresponding to the through hole 532. The lens 541 has a function of collecting light incident on the light receiving cover 54 from the front to the light receiving element 621 of the light receiving portion 62. In addition, on the right side of the light receiving cover 54, a lens portion 542 is provided at a position corresponding to the lens 541 and a light receiving element 621 that guides light incident from the lateral direction to the light receiving portion 62. Therefore, the light signal (control signal) transmitted from the transmitter 3 is received by the light receiving unit 62 via the light receiving cover 54. As described above, the light receiving portion 62 is covered by the light receiving cover 54 and therefore the light receiving portion 62 can be made inconspicuous when viewed from the outside. In addition, protrusions 59 are provided on the upper and lower portions of the right side of the light receiving cover 54 respectively.

The color of the light receiving cover 54 is the same color as the color of the transmitter body 30 of the transmitter 3, and is also the same color as the color of the handle body 50. Here, "the same color" is a color recognized as the same color or the same hue based on the color table of the Japanese Industrial Standards "JIS Z8102 Color Name of Object Color". In this embodiment, the color of the light receiving cover 54, the handle body 50, and the transmitter body 30 of the transmitter 3 is white, for example, but beige, silver, gray, dark brown, etc. may also be used. The colors of the light-receiving cover 54, the handle body 50, and the transmitter body 30 of the transmitter 3 can be set to the same color to achieve a unified color matching.

In this embodiment, the placement portion 53 of the light-receiving cover 54 is arranged at a part of the opposing part 530 (see FIG. 1) facing the lens 541 on the back of the light-receiving cover 54, that is, it is not connected to the rib of the switch body 4 A light-shielding portion 531 is provided at a portion where the portion 491 interferes. The light shielding part 531 is integrally provided with the handle 5 (specifically, the handle body 50). The light shielding portion 531 is provided with the above-mentioned through hole 532 into which the rib 491 of the switch body 4 is inserted. In other words, the light shielding portion 531 has a through hole 532 (hole) into which at least a part of the rib 491 is inserted. In addition, the handle body 50 has a protruding part 533 that protrudes toward the light receiving cover 54 around the light shielding portion 531 (upper and lower of the light shielding portion 531 in this embodiment) among the facing portions 530 facing the light receiving cover 54. 534. The light-shielding portion 531 has a lower light transmittance than the space in the hole of the through hole 532 that is not provided with the light-shielding portion 531 in the facing portion 530.

Here, the opposing part 530 of the mounting part 53 facing the lens 541 is inserted by the rib 491 that surrounds the light receiving part 62. Therefore, when considering dimensional accuracy or interference during assembly, it is better to Holes are opened in the entire facing portion 530. When the opposing part 530 is not provided with the light shielding part 531 and the opposing part 530 has all the holes, the part of the hole becomes dark, and there is a difference in brightness between the surface of the protruding parts 533 and 534. Therefore, in the case of the entire system hole of the opposing part 530, on the surface of the light-receiving cover 54, there is a difference in brightness between the parts corresponding to the protruding parts 533 and 534 and the part corresponding to the opposing part 530, which corresponds to the opposite There is a possibility that the part 530 will look dim. In the case of the entire system hole of the opposing part 530, in order to make the part corresponding to the opposing part 530 look dark, the entire light receiving cover 54 must be made a darker color than the handle body 50. In contrast, in the present embodiment, the opposing portion 530 has a light shielding portion 531 formed at a portion other than the through hole 532 into which the rib 491 is inserted. Therefore, compared with the case of the entire system of holes in the opposing portion 530 , Can reduce the uneven brightness on the surface of the light receiving cover 54. Thereby, even when the light-receiving cover 54 is fixed to the handle body 50, unevenness in brightness can be prevented from appearing on the surface of the light-receiving cover 54.

Furthermore, in this embodiment, the size of the rib 491 and the through hole 532 is set so that there is a gap between the rib 491 and the inner surface of the through hole 532. Therefore, as shown in FIG. 7A, the rib 491 and the handle body 50 does not interfere. Furthermore, as shown in FIG. 7B, when the handle 5 is rotated by pushing the right end of the handle 5, the possibility of interference between the rib 491 and the inner surface of the through hole 532 can also be reduced.

Moreover, in this embodiment, the mounting part 53 is provided with the protrusion parts 533 and 534 which protrude forward. Therefore, in the front-rear direction, the distance between the surface of the light receiving cover 54 and the surface (front surface) of the facing portion 530 of the mounting portion 53 can be longer than the surface (front surface) of the light receiving cover 54 and the protruding portions 533, The distance between the surface (front surface) of 534. Thereby, a space for arranging the lens 541 can be ensured between the surface of the light receiving cover 54 and the surface of the facing portion 530 of the placing portion 53.

In this embodiment, as shown in FIG. 7A, in the incident direction D1 of the light-receiving element 621 of the light-receiving portion 62, the tip of the rib 491 is located at the same position as the front surface 531a of the light-shielding portion 531, or The front end 492 of the rib 491 is positioned on the rear side than the front surface 531 a of the light shielding portion 531. Here, in the incident direction D1, the front end 492 of the rib 491 is located on the rear side than the front surface 531a of the light shielding portion 531, which means that the front end 492 of the rib 491 is located closer to the light receiving side than the front surface 531a of the light shielding portion 531. Location of element 621. That is, it means that the distance from the light receiving element 621 to the front end 492 of the rib 491 (third distance) is shorter than the distance from the light receiving element 621 to the front surface 531a of the light shielding portion 531 (fourth distance). Thereby, when the handle 5 is rotated by pushing the right end of the handle 5, the possibility of interference between the rib 491 and the light receiving cover 54 can also be reduced.

On the right side of the front surface of the handle 5, a through hole 56 that penetrates the handle 5 in the front-rear direction is provided at a portion facing the display portion 47 of the body 41. A translucent lens 57 is mounted on the back of the handle 5 (refer to FIG. 3). The translucent lens 57 is made of a transparent synthetic resin (for example, acrylic resin, etc.) molded product. The translucent lens 57 has an elliptical protrusion 571 whose front view shape is long in the vertical direction. The translucent lens 57 is fixed to the back surface of the handle 5 with the protrusion 571 inserted into the through hole 56. Thereby, when the handle 5 is mounted on the body 41, the light emitted by the display portion 47 is irradiated to the front side through the light-transmitting lens 57.

In addition, in this embodiment, the movable part, that is, the handle 5, is fixed at one end (left end) side in a certain direction (the short side direction of the handle 5 in this embodiment, and the direction parallel to the left and right direction). The switch body 4 is supported to be rotatable. Furthermore, the handle 5 has a light-transmitting lens 57 at the other end (right end) in the above direction. Thereby, the light of the display portion 47 is output through the light-transmitting lens 57 located at the end portion opposite to the end portion supported to be rotatable in the handle 5. Therefore, in a state where the transmitter 3 is removed from the handle 5, the user can judge the end of the handle 5 to be pushed and operated based on the light output through the transparent lens 57.

Furthermore, the translucent lens 57 is not limited to a transparent translucent member, and may be a translucent translucent member, or a dyed translucent member. In addition, the translucent lens 57 is not limited to a lens made of synthetic resin, and may be formed of glass or the like.

Also, on the back of the right side of the handle 5, an iron piece attracted by the magnetic force of a magnet built into the transmitter 3 is attached. Since the transmitter 3 has a magnet, it can be used to mount the transmitter 3 to a part formed of a ferromagnetic body such as iron. Furthermore, in the present embodiment, the handle 5 is equipped with an attraction member made of iron sheet, but the attraction member is not limited to iron, and may be formed of ferromagnetic metals such as iron or alloys thereof.

(2.2.2) Transmitter Next, the structure of the transmitter 3 will be described based on FIGS. 1 and 3.

The transmitter 3 includes a transmitter body 30 that is a synthetic resin molded product. The transmitter 3 can be attached to and detached from the handle 5 which is a movable part. The handle 5 can be used to hold the transmitter 3, and the size of the front surface of the load control device 1 can be reduced compared to the case where the transmitter 3 is held by parts other than the handle 5.

The transmitter body 30 is formed in a flat rectangular parallelepiped shape. The shape and size of the front surface of the transmitter body 30 are almost the same as those of the front surface of the handle 5 from which the mounting portion 53 is removed. Inside the transmitter body 30 are housed: a printed circuit board with circuits such as a transmitter-side light-emitting unit 71, an operation accepting unit 72, and a transmitter-side control unit 73; and a power source, namely a battery such as a button battery. The upper side surface of the transmitter body 30 is provided with a through hole 303 for exposing the light-emitting diode included in the transmitter-side light-emitting portion 71.

A film plate 33 is attached to the rear of the transmitter body 30. The film plate 33 is formed of a transparent synthetic resin into a plate shape and has flexibility. In the film plate 33, the light-transmitting area 332 corresponding to the protrusion 571 of the light-transmitting lens 57 provided on the handle 5 is transparent. In addition, parts of the film sheet 33 other than the light-transmitting area 332 are white.

The surface of the film plate 33 is provided with five operation parts 331 each projecting in a dome shape. The thin film plate 33 is formed with circular movable contacts by applying conductive ink to the back sides of the five operation portions 331 respectively. On the other hand, the printed wiring board housed inside the transmitter body 30 has a pair of fixed contacts formed by printing carbon paste, for example, at a location corresponding to each of the five operation portions 331. Here, a pair of fixed contacts and movable contacts constitute a switch.

When the user pushes the operating portion 331 to make the movable contact formed on the back side of the operating portion 331 contact a pair of fixed contacts, the pair of fixed contacts are electrically connected via the movable contact, and therefore the switch is turned on. On the other hand, when the operating portion 331 is not pushed, the pair of fixed contacts are electrically disconnected, and the switch is turned off. The operation accepting unit 72 of the transmitter 3 monitors the on/off states of the five switches, and when the switches are turned on, outputs an operation signal to the transmitter-side control unit 73. When the transmitter-side control unit 73 receives an operation signal from the operation acceptance unit 72, it sends a control signal in response to the user's operation from the transmitter-side light-emitting unit 71 to the switch main body 4.

In addition, the front surface of the transmitter body 30 is mounted with a decorative board 31 formed of a transparent synthetic resin (for example, acrylic resin, etc.) by bonding, ultrasonic welding, or the like. In the transmitter body 30, at a portion corresponding to the protrusion 571 of the handle 5, a through hole for penetrating the transmitter body 30 in the front-rear direction is provided. The rear surface of the decorative board 31 is integrally provided with a lens portion inserted into the through hole 303. The front surface of the decorative board 31 is provided with a protruding portion 311 protruding forward at a portion corresponding to the lens portion. Here, the lens portion and the protruding portion 311 constitute a light guide portion 35 that guides the light of the display portion 47 to the front side of the transmitter 3. The light guide 35 guides light from the rear surface side of the transmitter 3 to the front surface side, and can output the light incident from the rear surface side of the transmitter 3 from the front surface side. The decorative board 31 is manufactured using, for example, a two-color molding technique. For example, the lens portion is first molded, and the plate-shaped portion is molded on one end side of the lens portion, whereby the decorative board 31 can be integrally formed.

Inside the transmitter body 30, a magnet is housed in a position corresponding to the iron piece attached to the handle 5. The magnet is, for example, a rare earth magnet such as a neodymium magnet or a cobalt magnet.

In addition, the upper and lower parts of the left side of the transmitter body 30 are provided with grooves 302 (refer to FIG. 3), which are inserted by the protrusions 59 of the light receiving cover 54 provided on the handle 5.

The transmitter-side control unit 73 causes the transmitter-side light-emitting unit 71 to send a control signal corresponding to the operation signal input from the operation acceptance unit 72. When the light receiving unit 62 receives the control signal sent from the transmitter 3, the body-side control unit 65 controls the on/off of the semiconductor switch 61 in response to the control signal received by the light receiving unit 62, so that the load 200 is turned on or off. Here, the main body-side control unit 65 turns on the light emitting unit 64 when the load 200 is extinguished, and uses the light emitted by the light emitting unit 64 to light up the display unit 47 to display the installation position of the load control device 1. In addition, the main body-side control unit 65 blinks the light-emitting unit 64 during the execution of the timer operation, and uses the light of the light-emitting unit 64 to blink the display unit 47 to display the operating state of the load control device 1. Furthermore, when the transmitter 3 is detached from the handle 5, the light emitted by the display unit 47 is guided to the front of the handle 5 through the light-transmitting lens 57 of the handle 5. Therefore, the user can confirm the light emission of the display portion 47 and the display of the display portion 47 through the protrusion 571 of the transparent lens 57 of the handle 5.

In this embodiment, the main body 2 fixed to the construction surface is detachably provided with a transmitter 3, so the user can move the transmitter 3 removed from the main body 2 to a desired place for use.
