In addition, the medium for transmitting wireless signals may also be other mediums such as radio waves, and its purpose is not limited to infrared rays.

FIG. 2 is a block diagram showing a switch S. As shown in FIG. The switch S is provided with a load control unit 2 having a switching element (for example, a triac) that opens and closes a power supply path from the power source AC to the lighting load L, and the control circuit unit composed of a microcomputer 1 to switch and control the switching elements of the load control unit 2. In addition, the switch S includes: a wireless signal receiving part 3 having a light receiving element such as a photodiode or a phototransistor, and receiving a wireless signal using infrared rays as a medium; an amplifying circuit 4 for amplifying the received signal received by the wireless signal receiving part 3; Light-emitting elements such as diodes, and the display part 5 that performs the position display described later or the display (control state) of the validity/invalidity of the control based on the transmitter W1; has an intermittent switch that is pressed and operated by the operating handle 20, and in When the intermittent switch is turned on, an operation signal is sent to the switch input unit 6 of the control circuit unit 1 . That is, every time the operation handle 20 is pushed and an operation signal is sent from the switch input unit 6 , the control circuit unit 1 switches the switching element of the load control unit 2 to switch the lighting charge L on and off. In addition, the switch S is provided with a power supply circuit unit 7 for supplying operating power to the control circuit unit 1 and the like. When the load control unit 2 connects the power supply path from the power supply AC to the lighting load L, the power supply circuit unit 7 supplies power from the power supply AC to generate operating power, and at the same time, charges a capacitor not shown in the figure, and the load control unit 2 cuts off the power supply from the power source AC. When the power supply AC supplies power to the lighting load L, the electric charge charged in the capacitor is used to generate an operating power supply. Therefore, the switch S of the present embodiment can be connected to the power source AC and the lighting load L in series with two lines. However, since such a power supply circuit unit 7 is known in the art (for example, refer to Japanese Patent Laid-Open No. 2000-357443), illustration and description of the detailed structure and operation are omitted.

Here, the switch S of the present embodiment is configured as a delay switch. When the lighting load L is turned on, if the operation handle 20 is pressed to transmit an operation signal from the switch input unit 6, the control circuit unit 1 will start from the time when the operation signal is received.

Turn off the position display lamp during the period of lighting the lighting load L, and know the position of the switch S by lighting the position display lamp during the period of turning off the lighting load L. On the other hand, the control state display lamp is turned on when the control of the lighting load L by the transmitter W1 in the control circuit unit 1 is valid, and is turned off when the control of the lighting load L by the transmitter W1 is invalid.

FIG. 3 is a perspective view of the switch S. As shown in FIG. The body 10 of the switch S is composed of a rectangular box-shaped synthetic resin molded product, formed into two module sizes of a wide handle-shaped combined switch (refer to JIS C 8304), and installed on the installation frame 100 to be embedded in the wall. Here, the installation frame 100 can be installed by connecting three one-module-sized bodies along the width direction. In the illustrated example, it has the switch S of this embodiment, one-module-sized body 110 and an operating handle 111, and is connected to the・Install the wide handle-shaped switch S' that cuts off other loads and connects it. That is, since the switch S of this embodiment can be installed in parallel with the switch S' for turning on and off other loads using one mounting frame 100, space saving can be achieved. However, as shown in FIG. 4, the body 10 can also be formed into a module size. At this time, it can be connected with two switches S, S' having a body 110 of a module size and an operating handle 111 and installed on the mounting frame 100. . In addition, since this mounting frame 100 is a well-known mounting frame standardized in Japanese Industrial Standards and the like, illustration and description of details are omitted.

A printed circuit board on which electronic components constituting each part shown in FIG. 2 , terminals for connecting electric wires, and the like are housed in the body 10 . On the front of the body 10, a pair of shafts 11, 11 that are freely rotatably pivotally supported on the left end face of the central part in the up-down direction protrude, and are provided at the right end of the central part in the up-down direction to enable the intermittent switch. The circular hole 12 exposed by the button. In addition, two window holes 13a, 13b corresponding to the two light-emitting elements of the display unit 5 and windows corresponding to the light-receiving elements of the wireless signal receiving unit 3 are arranged in the vertical direction near the shaft portion 11 on the front of the body 10. hole 13c. Further, in the lower part of the front of the body 10, a narrow rectangular slot 14a and other slots 14b shorter than the slot 14a are provided, and the variable resistor for adjusting the delay time that the operation switch input unit 6 has is The operating handle 15a of the sliding switch that the switch input unit 6 has is slidably inserted into a long hole 14a in the left and right directions. Insert it into the other long hole 14b.

The operating handle 20 is formed of a synthetic resin material into a substantially rectangular shape in plan view, and a bearing (not shown) rotatably supported by the shafts 11, 11 is provided inside the left end in a front view. That is, the operating handle 20 is mounted on the front of the body 10 so as to be freely rotatable in the front-rear direction with the left end as a fulcrum by installing a bearing portion on the shaft portions 11, 11, and the right end surface is brought close to the body when pressing from the front. When the front side of 10 is used, the operation protrusion (not shown) protrudingly arranged on the back side operates the button of the intermittent switch exposed from the circular hole 12 .

In addition, three holes (not shown) corresponding to the three window holes 13a, 13b, and 13c are perforated at the left end of the operating handle 20, and a strip-shaped light-receiving window is installed in the form of blocking these three holes. Cover 21. The light-receiving cover 21 is made of a synthetic resin molded product that is translucent to infrared rays and has light-shielding properties to visible light, and is embedded in a position corresponding to the upper and lower window holes 13a, 13b to emit light from the position display lamp and the control status display lamp. The light guide members 21 a and 21 b for forward irradiation of light (visible light) allow the light when the position display lamp and the control state display lamp are lit to be seen without being blocked by the light receiving cover 21 .

Here, on the rear surface of the operating handle 20, a protrusion 22 protruding rearward is provided at the upper portion in the vertical direction, at the right end when viewed from the front. The protruding portion 22 is inserted into the insertion hole 16 provided on the upper right end when viewed from the front of the body 10 when the operating handle 20 is mounted on the front of the body 10 to operate a detection switch housed in the body 10 (Fig. not shown). The detection switch is constituted by, for example, a micro switch, and an operation signal (detection signal) is sent from the switch input unit 6 to the control circuit unit 1 when the protrusion 22 is operated. During the period when the detection signal is received, the control of the load control unit 2 corresponding to the received signal received by the wireless signal receiving unit 3 is enabled by the control circuit unit 1, and if the detection signal is not received, the control of the load control unit 2 corresponding to the received signal received by the wireless signal receiving unit 3 is enabled. The control of the load control unit 2 of the received signal received by the wireless signal receiving unit 3 becomes invalid. That is, the operating handle 20 has two types with the protruding portion 22 and without the protruding portion. In the case of combining with the transmitter W1 to form a load control system, the operating handle 20 with the protruding portion 22 can be mounted on the machine body 10 to be used. The control of the lighting load L based on the wireless signal is effective. In the case of using the switch S alone without combining with the transmitter W1, the operating handle 20 without the protrusion 22 can be installed on the body 10 to enable the lighting based on the wireless signal. The control of the load L becomes invalid. In addition, the operating handle 20 without the protrusion 22 does not need the light guide member 21a corresponding to the control state display lamp. In the state where the operating handle 20 is installed, the control state cannot be seen because it is hidden by the light receiving cover 21. Since the light is displayed, it can be easily judged whether or not the control of the lighting load L by the transmitter W1 is effective.

FIG. 5 shows a block diagram of the transmitter W1. The transmitter W1 is equipped with a sensor that detects the presence or absence of a person in the detection area by detecting infrared rays radiated from the human body by using a pyroelectric element, and a sensor that detects the surrounding brightness by a photoelectric conversion element or a solar cell, And send the surrounding brightness detected by the brightness sensor and the sensor part 31 whether there is a person detected by the human sensor. The brightness sent from the sensor unit 31 and the detection result of the human body are input to the control circuit unit 30 constituted by a microcomputer. In the control circuit unit 30, when a human body is detected by the sensor unit 31, the lighting load L point is generated. Control signal for lighting. In addition, the control signal generated by the control circuit unit 30 includes: a signal in which the brightness detected by the brightness sensor does not reach the threshold value (hereinafter referred to as "first control signal") and a signal in which the brightness detected by the brightness sensor is above the threshold value (hereinafter referred to as "first control signal"). Referred to as "second control signal") two. Then, the first and second control signals generated by the control circuit unit 30 are amplified by the amplifier circuit 32 and sent to the wireless signal transmission unit 33 . And, the wireless signal sending part 33 drives the light-emitting diode (not shown in the figure) according to the first and second control signals of the control circuit part 30, and sends the wireless signal (first or second) using the infrared rays generated by the light-emitting diode as a medium. control signal). In addition, the transmitter W1 is provided with the switch circuit part 34 having the button switch SW1 for forcibly turning on or off the lighting load L regardless of the detection of the presence or absence of a person based on the sensor part 31. The circuit unit 34 sends out an operation signal, obviously causing the control circuit unit 30 to generate a control signal for turning on or off the lighting charge L (hereinafter referred to as "third control signal"). Further, the switch circuit section 34 has a setting switch (variable resistor) for setting a threshold value for the luminance sensor so that the control circuit section 30 sets the threshold value based on a setting signal sent from the switch circuit section 34 . In addition, the transmitter W1 is provided with a power supply unit 35 that uses a battery as a power supply to supply operating power to each part.

FIG. 6 shows an external view of the transmitter W1. The transmitter W1 has a case 40 made of a synthetic resin body 40a and a cover 40b, and a printed circuit board (not shown) on which electronic components constituting each part shown in FIG. 5 are installed in the case 40. . The main body 40a has a rectangular plate shape, and is mounted on the wall by erecting pins 41 inserted into the four corners from the front. The cover 40b has a substantially rectangular shape in planar view, and covers the front of the main body 40a. In the lower part of the cover body 40b, the lens 42 for the human sensor that gathers infrared rays to the sensor part 31 is provided, and in the upper part of the cover body 40b, the infrared light emitted by the light-emitting diode LD for wireless signal transmission that the wireless signal transmission part 33 has is provided. The infrared transmission part 43. In addition, an operation portion 44 for operating a button of the push button switch SW1 and an external light transmission portion 45 for irradiating external light to the brightness sensor are arranged in a central portion of the cover body 40b. In addition, instead of using the pressing pin 41, as shown in FIG. 7, a double-sided tape 46 may be adhered to the back surface of the case 40 to stick to the wall.

Next, the operation of this embodiment will be described. When the operating handle 20 is pressed and operated from the state where the lighting load L is turned on (forced lighting) after the operating handle 20 is pressed, the control circuit unit 1 counts the set delay time T1 (delay operation). When the counting of the time T1 (time-out) ends or the operation handle 20 is pressed again during the counting of the delay time T1, the load control unit 2 is controlled to turn off the lighting load L (forced to turn off). In addition, the control circuit unit 1 controls the display unit 5 to turn off the position display lamp in the forcibly turned on state, blink the position display lamp during counting of the delay time, and turn on the position display lamp in the forcibly turned off state.

On the other hand, in the transmitter W1, for example, when the lighting load L is turned off and the ambient brightness does not reach the threshold value, if the sensor unit 31 detects that there is a person in the detection area, the control circuit unit 30 generates a first control signal On the other hand, a wireless signal (first control signal) is transmitted from the wireless signal transmission unit 33 . In the control circuit part 1 of the switch S that has received the first control signal, if the switching element of the load control part 2 is turned off, that is, the lighting load L is turned off, then the switching element of the load control part 2 is turned on. While the lighting load is turned on, the count of the operation holding time T2 is set in advance, and when the counting of the operation holding time T2 is completed, the load control part 2 (cutting off the switching element) is controlled to turn off the lighting load L. In addition, if the sensor unit 31 detects the presence of a person again during the counting of the operation holding time T2, since the lighting load L is turned on and the surrounding brightness is equal to or greater than the threshold value, the control circuit unit 30 of the transmitter generates a second control signal and A wireless signal (second control signal) is transmitted from the wireless signal transmission unit 33 . In the control circuit unit 1 of the switch S that received the second control signal, when the switching element of the load control unit 2 is turned on, that is, the lighting load L is turned on, the pre-trigger operation keeps counting the time T2. However, if the switching element of the load control unit 2 is turned off when receiving the second control signal, that is, the lighting load L is turned off, and the control circuit unit 1 still turns off the lighting load L because the surrounding brightness is considered to be above the threshold value. Control by the load control unit 2 is not performed. Here, since the operation holding time T2 and the delay time T1 are shared by the control circuit part 1 of the switch S, it is not necessary to provide a timer for counting the operation holding time T2 on the transmitter W1, and the structure of the transmitter W1 can be simplified. In addition, when the control circuit unit 1 is equipped with the operating handle 20 having the protrusion 22 , the control display unit 5 is controlled to turn on the control state display lamp to indicate that the control by the wireless signal (wireless control) is effective.

FIG. 8 shows a state transition diagram of the control circuit unit 1 when the operation handle 20 without the protrusion 22 is attached to the body 10 . If the operating handle 20 is pressed and operated from the state where the lighting charge L is lit, the control circuit portion 1 counts the set delay time T1 (delay operation), and if the count of the delay time T1 ends (time is up), or When the operating handle 20 is pressed again during the count of the delay time T1, the load control unit 2 is controlled to turn off the lighting load L. In addition, when the operating handle 20 is pressed from the state where the lighting load L is turned off, the control circuit unit 1 controls the load control unit 2 to turn on the lighting load L (see FIG. 9 ). Moreover, the control circuit unit 1 controls the display unit 5 to turn off the position display lamp in the lighting state of the lighting load L, blink the position display lamp during the counting of the delay time, and display the position display in the lighting state of the lighting load L. The lights come on. However, when the operating handle 20 without the protrusion 22 is attached to the body 10, the control circuit unit 1 controls the display unit 5 to turn off the control state indicator lamp to indicate that the wireless control is disabled.

As described above, the switch S and the load control system of this embodiment can be used in combination with the transmitter W1 that detects the presence of a person in the detection area and then transmits a wireless signal, so that other switch functions can be easily added without rewiring. . However, since the transmitter W1 having the human presence sensor for detecting human presence is separated from the switch S for controlling the blinking of the lighting load L, it is easy to install the transmitter W1 at a position where an optimum detection area is obtained.

However, whether or not to disable wireless control in the control circuit part 1 of the switch S is switched by pressing the operating handle 20 instead of the presence or absence of the protrusion 22 of the operating handle 20 attached to the body 10 . For example, as shown in the state transition diagram of FIG. 10 , when the lighting load L is turned on (except for the count of the delay time) or turned off, and the operation handle 20 is continuously pressed for a longer time than usual (for example, during 2 seconds), When the control circuit unit 1 enables the wireless control, or when the lighting load L is turned on or off through the wireless control, if the operation handle 20 is pressed and operated, the control unit circuit unit 1 disables the wireless control. Or, as shown in the state transition diagram of FIG. 11 , the control circuit part 1 can also cycle switch the lighting of the lighting load L → (delay action) → extinguishing of the lighting load L → effective of the wireless control every time the operating handle 20 is pressed. →Lighting of the lighting load L.

(Embodiment 2)

As shown in FIG. 12, the load control system of this embodiment is characterized by including a transmitter W2 having a timer function (described later) in addition to the transmitter W1 equipped with a human sensor and a brightness sensor. However, since the configuration and operation of the switch S and the transmitter W1 are the same as those in the first embodiment, the same reference numerals are assigned to common components and descriptions thereof are omitted.

FIG. 13 shows a block diagram of the transmitter W2. The transmitter W2 is provided with a timer circuit section 51 for measuring the current time, and data of the current time measured by the timer circuit section 51 is input to the control circuit section 50 composed of a microcomputer. In the control circuit section 50, when the current time counted by the timer circuit section 51 coincides with a preset time (control time), a control signal for turning on or off the lighting load L is generated. Then, the control signal generated by the control circuit unit 50 is amplified by the amplifier circuit 52 and then sent to the wireless signal transmission unit 53 . Furthermore, the wireless signal transmission unit 53 drives the light emitting diode LD according to the control signal of the control circuit unit 50, and transmits a wireless signal (control signal) through the infrared rays emitted by the light emitting diode LD. In addition, the transmitter W2 is provided with: a switch circuit part 54 having setting switches 34a to 34d for setting the control time; The setting signal sent by the circuit part 54 controls the circuit part 50 to set the control time, and at the same time controls the liquid crystal circuit part 55 to display the current time and the control time on the liquid crystal display part 55a. In addition, the transmitter W2 is provided with a power supply unit 56 that uses a battery as a power supply to supply operating power to each part.

FIG. 14 shows an external view of the transmitter W2. The transmitter W2 has a case 60 made of a flat box-shaped synthetic resin molded product, and a printed circuit board (not shown) on which electronic components constituting each part shown in FIG. 13 are mounted in the case 60 . In addition, the casing 60 is installed on the wall using a push pin or a double-sided tape, similarly to the transmitter W1. An infrared ray transmission unit 61 for transmitting infrared rays emitted by a light emitting diode LD for wireless signal transmission included in the wireless signal transmission unit 53 is provided on the upper portion of the housing 60 . In addition, a liquid crystal display 55a is arranged at the center of the front surface of the casing 60, and operation buttons 62a to 62d of four operation switches (not shown) included in the operation switch circuit unit 54 are provided below it. Every time the operation button 62 a is pressed and an operation signal is input from the switch circuit unit 54 , the control circuit unit 50 switches to the current time setting mode→the control time setting mode→the normal mode. In the current time setting mode, the operation signal is input from the switch circuit part 54 by pressing the operation buttons 62b, 62c, so that the control circuit part 50 sends forward or reversely sends the current time of the timing circuit part 51, and at the same time, the liquid crystal circuit is controlled. unit 55 to update the current time display on the liquid crystal display 55a. And, if the operation button 62d is pressed and operated and an operation signal is input from the switch circuit portion 54, the control circuit portion 50 sets the time displayed on the liquid crystal display 55a at that time as the current time on the timer circuit portion 51, and Return to the normal mode from the current setting mode. In the control timing setting mode, the control timing (lighting timing) for lighting the lighting load L and the control timing (lighting timing) for turning off the lighting load L are selected by pressing and operating the operation buttons 62b and 62c. , the control circuit unit 50 sets the turn-on time and the light-off time. Here, in this embodiment, two types of timing control can be selected: "punctual" and "door-watching". In "punctual", the lighting load L is turned on and off through the lighting time and extinguishing time set each time (every day). In the "gatekeeper", the lighting load L is turned on and off at a randomly determined time every time (every day) within a range of, for example, 30 minutes before and after the set turning-on time and extinguishing time. That is, when the resident goes out for several days, if the lighting load L is turned on and off at the same time every day, it is recognized that the lighting load is automatically turned on and off, but the lighting load L is turned on and off by randomly changing every day. time, it is difficult to see through.

Next, the operation of this embodiment will be described. Furthermore, it is assumed that in the transmitter W2, the turn-on time is set to 6:00 pm, and the light-off time is set to 9:00 pm. Then, before 6:00 pm, according to the wireless signal sent from the transmitter W1, the control circuit part 1 of the switch S keeps the lighting load L only on for a time T2. When it becomes 6 pm (lighting time), the control circuit unit 50 of the transmitter W2 generates a control signal for lighting the lighting load L, and transmits a wireless signal (control signal) from the wireless signal transmission unit 53 . In the control circuit section 1 of the switch S that has received the control signal, the switching element of the load control section 2 is turned on to light the lighting load L, and at the same time, the wireless signal (the first and the first) transmitted from the transmitter W1 is not received. state of the second control signal). However, when the operating handle 20 on which the switch S is operated is pressed, the control circuit unit 1 controls the load control unit 2 to blink the lighting load L. FIG. Then, at 9:00 p.m. (turn-off time), the control circuit unit 50 of the transmitter W2 generates a control signal for turning off the lighting load L, and transmits a wireless signal (control signal) from the wireless signal transmission unit 53 . In the control circuit section 1 of the switch S that has received the control signal, the switching element of the load control section 2 is turned off to turn off the lighting load L, and at the same time, it becomes to receive the wireless signal transmitted from the transmitter W1 (first and second control signal) state. In addition, in the control circuit part 1 of the switch S, it is set not to receive the wireless signal from the transmitter W1 during the period from 0:00 am to 8:00 am by the wireless signal transmitted from the transmitter W2, thereby preventing late-night lighting. Dizziness caused by lighting load L.

Moreover, in the case of combining the existing infrared automatic switch and the timer switch, if the two switches are connected in parallel between the power supply AC and the lighting load L, since each switch can operate independently, it is impossible to prohibit the automatic switch from the infrared automatic switch. The automatic switch controls the lighting load L. In addition, if two types of switches are connected in series between the power supply AC and the lighting load L, neither switch alone can light the lighting load L. On the other hand, in this embodiment, as described above, the lighting load L can be independently controlled by the two types of transmitters W1 and W2, and the control operation of one transmitter W1 can be prohibited from the other transmitter W2.

(Embodiment 3)

As shown in FIG. 16 , the load control system of this embodiment is characterized in that it includes a transmitter W3 that transmits a wireless signal when the operating handle is pressed. However, since the configuration and operation of the switch S are the same as those of the first embodiment, the same reference numerals are assigned to the common components and descriptions thereof are omitted.

FIG. 17 shows a block diagram of the transmitter W3. The transmitter W3 is provided with a switch circuit unit 71 having a push button switch (not shown) that is pressed and operated by an operating handle. When the push switch is turned on, an operation signal is sent from the switch circuit unit 71 to the control circuit unit 70 . The control circuit unit 70 is composed of a microcomputer, and generates a control signal for turning on or off the lighting load L when receiving an operation signal from the switch circuit unit 71 . Then, the control signal generated by the control circuit unit 70 is amplified by the amplifier circuit 72 and sent to the wireless signal transmission unit 73 . In addition, the wireless signal control unit 73 drives the light-emitting diodes based on the control signal from the control circuit unit 70, and transmits wireless signals (control signals) through infrared rays emitted by the light-emitting diodes. In addition, the transmitter W3 is provided with a power supply unit 74 that uses a battery as a power supply to supply operating power to each part.

In addition, the transmitter W3 has a casing 80 made of a box-shaped synthetic resin molded product, and a printed circuit board (not shown) on which electronic components constituting each part shown in FIG. 17 are mounted in the casing 80. , an operating handle is mounted on the front of the housing 80 so as to be freely rotatable in the front-rear direction with one end side as a fulcrum. However, since the mounting structure to the housing 80 of the operating handle is the same as the mounting structure to the operating handle 20 of the body 1 of the switch S, illustration and description are omitted. In addition, the case 80 is attached to the wall using a push pin or a double-sided tape similarly to the transmitters W1 and W2.

Then, when the operating handle is pressed, the control circuit unit 70 generates a control signal and transmits a wireless signal (control signal) from the wireless signal transmitting unit 73 . In the control circuit unit 1 of the switch S that received the control signal, when the switching element of the load control unit 2 is turned off, it is turned on, and when it is turned on, the lighting load L is turned on or off by turning off. Therefore, by adding the transmitter W3 of this embodiment to the system, the functions of the 3-way switch and the 4-way switch can be added without rewiring.
