Description

Wall switch

The present invention relates to a wall switch.

Conventionally, the lighting load is turned on in response to an ON operation of the push operation unit, and the illumination load is turned off in response to an OFF operation of the push operation unit. There is an illumination control switch for dimming the light (for example, Japanese Patent Application Publication No. 2008-4520 (hereinafter referred to as “Document 1”)). This illumination control switch has a brightness setting volume for setting the dimming level in the dimming time zone.

The lighting control switch described in Document 1 turns off the lighting load after turning on the lighting load for a predetermined time at a predetermined lighting level darker than the lighting level before the turning-off operation when the push operation unit is turned off. It had a function. In this lighting control switch, the dimming level in the dimming time zone was changed using the brightness setting volume with the lighting load dimmed until a certain period of time had passed since the off operation. Even in the case, the lighting load was turned off after a certain period of time.

By the way, as a switch for lighting control, a switch having a dimming function for dimming the lighting load according to a dimming operation, and a delayed turning-off function for turning off the lighting load after a certain time since the turning-off operation is performed are provided. Conventional switches have been proposed.

And with diversification of customer needs, a switch having both dimming function and delayed turn-off function is desired.

However, when a switch with both dimming and delayed turn-off functions is used, an operator who misunderstands that the lights are turned off if the lighting load is lit at a dark dimming level in the daytime when the surroundings are bright. There is a possibility of actually performing an off operation when trying to perform an on operation. Then, when the operator who intends to perform the on operation continues to perform the dimming level setting operation, even if the dimming level setting operation is performed, the delay extinguishing function turns off the light after a predetermined time has elapsed. For this reason, there has been a problem that the dimming level setting operation that has been performed is wasted.

The present invention has been made in view of the above problems, and its object is to dimm the lighting load without turning off the delay when a dimming level setting operation is performed during the delayed turn-off. It is to provide a wall switch that can.

In order to solve the above problems, the wall switch of the present invention includes a first operation input unit (2), a second operation input unit (3), and a lighting control unit (4). The first operation input unit (2) is configured to receive a lighting operation for turning on the lighting load (100) and a turn-off operation for turning off the lighting load (100). The second operation input unit (3) is configured to accept a setting operation for setting the dimming level of the illumination load (100). The lighting control unit (4) lights the lighting load (100) when the first operation input unit (2) accepts the lighting operation, and responds to the setting operation when the second operation input unit (3) accepts the setting operation. It is configured to control the dimming level of the lighting load (100). When the first operation input unit (2) receives a turn-off operation while the lighting load (100) is turned on, the lighting control unit (4) turns on the lighting load (100) when a predetermined delay time has elapsed since the turn-off operation. Is provided with a delayed turn-off function (116) configured to turn off the light. Then, when the second operation input unit (3) receives the setting operation between the time when the light-off operation and the delay time elapse, the lighting control unit (4) invalidates the delay light-off function (116) and sets the setting operation. The lighting load (100) is dimmed and lit at a dimming level according to the above.

In the state where the wall switch of the present invention is dimming and lighting the lighting load in the daytime when the surroundings are bright, etc. There is a case where an operation for setting the dimming level is performed. According to the present invention, when the second operation input unit accepts the setting operation between the first operation input unit accepting the extinguishing operation and the delay time elapses, the lighting control unit disables the delay extinguishing function. Thus, the illumination load is lit at the dimming level set by the setting operation even after the delay time has elapsed. Therefore, the lighting load is lit as intended by the operator who has set the dimming level, so the work of setting the dimming level performed by the operator is not wasted, and illumination is performed at the dimming level intended by the operator. The load can be lit.

For example, the delayed turn-off function 116 includes a timer function. The dimming priority function 117 disables the delay light extinction function 116 when the second operation input unit 3 accepts a setting operation between the time when the light is turned off and the delay time elapses.

Hereinafter, a configuration example of the wall switch 1 will be described. The wall switch 1 includes a signal processing unit 11, a plurality of touch sensors 12, an output circuit 13, a plurality of light emitting diodes (LEDs) 14, a buzzer 15, drive circuits 16 and 17, and a power supply circuit 18. And a memory 19. The circuit board on which the circuit components constituting the circuit of FIG. 1 are mounted is housed inside the container body 20. For example, as shown in FIG. 4, the plurality of touch sensors 12 are mounted on one surface 120 a of the (first) circuit board 120 to constitute a touch sensor module. The circuit board 120 is housed inside the container body 20 so that the surface 120a of the circuit board 120 faces the back surface of the operation area 20a of the container body 20. The circuit board 120 is formed with a plurality of through holes 120b disposed in front of the plurality of light emitting diodes 14, respectively. That is, the plurality of light emitting diodes 14 are placed on another circuit board 121 (hereinafter referred to as “second circuit board”) disposed on the back surface of the circuit board 120 so as to be positioned behind the plurality of through holes 120b. It is mounted (see FIG. 2).

Specifically, the signal processing unit 11 is configured by a microcomputer, for example, and is configured to perform overall control of the wall switch 1. In the example of FIG. 1, the signal processing unit 11 includes a lighting operation input unit 111, a dimming operation input unit 112, a lighting dimming control unit 113, and the like. The lighting dimming control unit 113 includes the lighting function 114, the dimming function 115, the delayed extinguishing function 116, and the dimming priority function 117. When detecting the tap operation or the slide operation based on the output of the touch sensor 12 (touch sensor module), the signal processing unit 11 performs load control according to the detected operation content (tap operation or slide operation). In the present embodiment, the signal processing unit 11 (lighting operation input unit 111) is configured to switch on and off the lighting load 100 according to a tap operation. In addition, when the signal processing unit 11 (the dimming operation input unit 112) detects an upward slide operation, the signal processing unit 11 (the dimming operation input unit 112) sets the dimming level of the illumination load 100 to a brighter level. It is configured to set the dimming level to a darker level.

The plurality of touch sensors 12 are each configured by a capacitance type sensor, and the output of each touch sensor 12 is input to the signal processing unit 11 (the lighting operation input unit 111 and the dimming operation input unit 112). Yes. The plurality of touch sensors 12 are arranged at equal intervals on the back side of the front wall of the container body 20 so as to be arranged in one or two rows along the vertical direction. In the example of FIG. 4, the plurality of touch sensors 12 are arranged at equal intervals on both sides of the plurality of through holes 120b arranged along the direction D1. Since the container body 20 is made of a synthetic resin, when a finger touches the front surface of the container body 20, that is, the operation area 20 a for performing a tap operation or a slide operation, a touch sensor located near the back side of the part touched by the finger. The capacitance value of 12 changes, and the output of the touch sensor module changes accordingly. The plurality of touch sensors 12 are adjacent to each other such that the detection ranges of the adjacent touch sensors 12 partially overlap. In the example of FIG. 4, the plurality of touch sensors 12 are arranged from the vicinity of the end (upper end) of the first body 20 in the direction D1 to the vicinity of the end (lower end) of the second body 20 in the direction D1. Therefore, the operation can be detected in substantially the entire operation area 20a in the vertical direction. Here, the tap operation means an operation of tapping the operation area 20a with a finger, and the slide operation means an operation of tracing the operation area 20a with a finger. In the example of FIG. 4, the plurality of touch sensors 12 have a shape in which the gap between the adjacent touch sensors 12 has a triangular wave shape, but the plurality of touch sensors of the present invention is not limited to this. For example, the plurality of touch sensors of the present invention may have a shape (for example, a rectangular shape) in which a gap between adjacent touch sensors is linear.

The output circuit 13 is configured to change the voltage level of the output signal S1 in accordance with a control command from the signal processing unit 11 (lighting dimming control unit 113). The output signal S1 of the output circuit 13 is input to the lighting load 100, and the lighting load 100 is configured to control the dimming level of a light emitting diode (not shown) as a light source in accordance with the voltage level of the output signal S1. The

Each of the plurality of (for example, seven) light emitting diodes 14 is composed of, for example, RGB full color light emitting diodes. The plurality of light emitting diodes 14 are arranged at equal intervals on the back side of the front wall of the container body 20 so as to be aligned in a line along the direction D1 (vertical direction). In the present embodiment, the plurality of light emitting diodes 14 are mounted on the second circuit board 121 disposed on the back surface of the circuit board 120 so as to be positioned behind the plurality of through holes 120b of the circuit board 120, respectively. . Specifically, the circuit board 120 is disposed on the first side in the direction (front-rear direction) orthogonal to the direction D1, while the second circuit board 121 is disposed on the second side in the direction (front-rear direction). The front wall of the container body 20 is formed to a thickness that allows the light emission of the light emitting diode 14 to pass therethrough.

The drive circuit 16 is configured to turn on / off the plurality of light-emitting diodes 14 and to individually control the emission color when the light-emitting diodes 14 are turned on in accordance with an input signal from the signal processing unit 11. In other words, the signal processing unit 11 is configured to turn on / off the plurality of light emitting diodes 14 and to supply signals to the drive circuit 16 for individually controlling the emission color when the light emitting diodes 14 are turned on. Is further included.

The drive circuit 17 sounds the buzzer 15 according to the input signal from the signal processing unit 11. In other words, the signal processing unit 11 further includes a function configured to supply the drive circuit 17 with a signal for sounding the buzzer 15.

The power circuit 18 includes an AC / DC converter 18a and an LDO (Low Drop-Out) regulator 18b. The AC / DC converter 18a is configured to convert AC power supplied from a commercial AC power source into DC. The LDO regulator 18b is configured to step down the output voltage of the AC / DC converter 18a to a predetermined voltage and supply it to the signal processor 11. The configuration of the power supply circuit 18 is not limited to this embodiment, and can be changed as appropriate.

The memory 19 is composed of, for example, an electrically rewritable nonvolatile memory, and is configured to store the dimming level of the illumination load 100. For example, the memory 19 is composed of an EEPROM or the like.

Here, the signal processing unit 11 is configured to perform different load control when the tap operation is performed and when the slide operation is performed. The lighting operation input unit 111 and the dimming operation input unit 112 are performed in the following manner, respectively.

The sensor output corresponding to the capacitance value is input to the signal processing unit 11 from each of the plurality of touch sensors 12. Based on the sensor output input from each touch sensor 12, the signal processing unit 11 compares the capacitance value of each touch sensor 12 with a predetermined reference value to thereby detect each touch in the operation region 20a. It is determined whether or not a finger (human body) is touching a part corresponding to the sensor 12. Further, the arrangement of the touch sensors 12 is registered in the signal processing unit 11 in advance.

When the operator's finger touches the operation area 20a, the signal processing unit 11 detects the position of the touch sensor 12 that first detects that the finger is touched, and the touch that lastly detects that the finger is touched. Based on the position of the sensor 12, the amount of movement of the finger touching the operation area 20a is obtained. The signal processing unit 11 compares the amount of movement of the finger obtained in the above process with a predetermined threshold, and if the amount of movement of the finger is smaller than the threshold, the lighting operation input unit 111 determines that it is a tap operation. If the amount of finger movement is equal to or greater than the threshold, the light control operation input unit 112 determines that the operation is a slide operation. In addition, when the signal processing unit 11 (the dimming operation input unit 112) determines that the operator's operation is a slide operation, the position of the touch sensor 12 that first detected that the finger touched and the touch of the finger The direction of the slide operation is determined from the result of comparison with the position of the touch sensor 12 that detected the last. That is, if the position of the touch sensor 12 detected last is the second side (lower side) in the direction D1 rather than the position of the touch sensor 12 first detected that the finger touched, the signal processing unit 11 Determines that the direction of the slide operation is the second side (downward) in the direction D1. On the other hand, if the position of the touch sensor 12 detected last is higher than the position of the touch sensor 12 first detected that the finger touched, the signal processing unit 11 slides. It is determined that the direction of operation is the first side (upward) of the direction D1. Note that the above threshold value is set in advance, which is larger than a value that can be regarded as a finger not moving and smaller than an average movement amount when a slide operation is performed.

In the present embodiment, the lighting operation for turning on the lighting load 100 and the turning-off operation for turning off the lighting load 100 include an operation of tapping the operation area 20 a of the container 20. The setting operation for setting the level includes an upward or downward slide operation. And the 1st operation input part 2 which receives lighting operation and light extinction operation is a signal processing part comprised so that a touch operation may be detected based on the sensor output of the touch sensor 12 and the touch sensor 12 (touch sensor module). 11 (lighting operation input unit 111). In addition, the second operation input unit 3 that receives the setting operation includes a touch sensor 12 (touch sensor module) and a signal processing unit 11 (adjustment unit) configured to detect a slide operation based on the sensor output of the touch sensor 12. And an optical operation input unit 112). In addition, the 1st operation input part 2 and the 2nd operation input part 3 are not limited to the structure of this embodiment, Tap operation and double tap operation are performed for the 1st operation input part 2 and the 2nd operation input part 3. An operation input unit that detects an operation different from each other, such as a slide operation or a touch operation with a finger. Moreover, you may comprise the 1st operation input part 2 and the 2nd operation input part 3 with switches, such as a separate pushbutton switch.

Next, the operation of the wall switch 1 will be described. When the signal processing unit 11 (lighting operation input unit 111 and dimming operation input unit 112) detects a tap operation or a slide operation by the operator as described above, the signal processing unit 11 (lighting dimming control unit 113). ) Performs load control according to the tap operation or the slide operation, and FIG. 3 shows a state transition diagram representing the operation.

In the state where the illumination load 100 is turned off (state ST1), the signal processing unit 11 controls the drive circuit 16 to display the position by turning on only the light emitting diode 14 at the center in the vertical direction, for example, green. .

When the operator performs an operation (tap operation) to tap the operation area 20a with a finger while the lighting load 100 is turned off (event t1), the signal processing unit 11 (lighting operation input unit 111) is touched by the touch sensor 12 (sensor module). ) Detects the tap operation based on the sensor output. When detecting the tap operation, the signal processing unit 11 reads the dimming level at the previous lighting from the memory 19. The signal processing unit 11 (lighting dimming control unit 113) outputs a dimming signal S1 corresponding to the read dimming level from the output circuit 13 to the lighting load 100, and the lighting load 100 is set to the dimming level at the previous lighting time. Turn on (state ST2). In addition, the signal processing unit 11 controls the drive circuit 17 to generate a notification sound (for example, a sound of “pi”) from the buzzer 15 to notify the operator that the touch operation has been accepted. Further, the signal processing unit 11 controls the drive circuit 16 to light up n light emitting diodes 14 from the lower side (where the number n is a number corresponding to the dimming level) and turn the remaining light emitting diodes 14 to green. By lighting up, the dimming level is visually displayed.

When the lighting load 100 is dimmed (state ST2) and the operator performs a tap operation on the operation area 20a (event t2), the signal processing unit 11 (lighting operation input unit 111) is touched by the touch sensor 12. The tap operation is detected based on the sensor output. When the signal processing unit 11 (lighting dimming control unit 113) detects a tap operation during lighting, the signal processing unit 11 (lighting dimming control unit 113) starts a time delay operation for a predetermined delay time (for example, set between 3 seconds and several minutes), and delays the delay time. While the operation is performed, the lighting state of the illumination load 100 is maintained (state ST3).

Then, when the time limit operation for the delay time is completed without the operator operating the operation area 20a (event t3), the signal processing unit 11 (lighting dimming control unit 113) is connected from the output circuit 13 to the illumination load 100. An extinguishing signal is output, and the illumination load 100 is extinguished (state ST1). In addition, the signal processing unit 11 controls the drive circuit 17 to sound a notification sound (for example, a “beep” sound) from the buzzer 15 to notify that it has been switched to the off state. Further, the signal processing unit 11 controls the drive circuit 16 so that only the light emitting diode 14 at the center in the vertical direction, for example, is lit in green to notify that it has been switched to the off state.

Further, when the signal processing unit 11 performs the time limit operation of the delay time (state ST3), when the operator taps the operation area 20a to cancel the turn-off operation (event t4), signal processing is performed. The unit 11 (lighting operation input unit 111) detects a tap operation based on the sensor output of the touch sensor 12. At this time, the signal processing unit 11 (lighting dimming control unit 113) disables the time delay operation (delay extinguishing function) and continues the dimming lighting of the lighting load 100 (state ST2).

In addition, when the operator performs a slide operation of the operation area 20a in a state where the lighting load 100 is dimmed (state ST2) (event t5), the signal processing unit 11 (the dimming operation input unit 112) A slide operation and its operation direction are detected based on the sensor output of the touch sensor 12. When the operation direction of the slide operation is upward, the signal processing unit 11 (lighting dimming control unit 113) brightens the dimming level read from the memory 19 by a predetermined amount, and the changed dimming level is stored in the memory 19. Store (state ST4). When the operation direction of the slide operation is downward, the signal processing unit 11 (lighting dimming control unit 113) darkens the dimming level read from the memory 19 by a predetermined amount and stores the changed dimming level in the memory. 19 (state ST4). When the dimming level setting is changed according to the slide operation as described above, the signal processing unit 11 (lighting dimming control unit 113) outputs the dimming signal S1 corresponding to the changed dimming level as an output circuit. 13 is output to the illumination load 100 (event t7), and the illumination load 100 is turned on at the dimming level after the change (state ST2). Further, the signal processing unit 11 controls the drive circuit 16 to light up n light emitting diodes 14 (the number n is a number corresponding to the dimming level after the change) from the lower side, and the remaining light emitting diodes. The light control level is visually displayed by lighting 14 in green. The time from when the slide operation is performed until the brightness level of the lighting load 100 is changed after the dimming level setting is changed is about 0.1 to 0.5 seconds, and the response to the operation is The time is short enough for the operator not to feel the slowness.

In addition, when the operator performs a slide operation to change the light control level in the state where the light is turned off (state ST3) (event t6), the signal processing unit 11 (light control operation input unit 112) The slide operation and the operation direction are detected based on the sensor output of the touch sensor 12. When the operation direction of the slide operation is upward, the signal processing unit 11 (lighting dimming control unit 113) brightens the dimming level read from the memory 19 by a predetermined amount, and the changed dimming level is stored in the memory 19. Store (state ST4). When the operation direction of the slide operation is downward, the signal processing unit 11 (lighting dimming control unit 113) darkens the dimming level read from the memory 19 by a predetermined amount and stores the changed dimming level in the memory. 19 (state ST4). When the setting of the dimming level is changed according to the slide operation, the signal processing unit 11 (lighting dimming control unit 113) sends the dimming signal S1 corresponding to the changed dimming level from the output circuit 13 to the illumination load. 100 (event t7), and the lighting load 100 is turned on at the dimming level after the change (state ST2). Further, the signal processing unit 11 controls the drive circuit 16 to light up n light emitting diodes 14 (the number n is a number corresponding to the dimming level after the change) from the lower side, and the remaining light emitting diodes. The light control level is visually displayed by lighting 14 in green. As a result, when the dimming operation is performed and the dimming lighting is performed while waiting for the extinguishing, when another operator performs a slide operation to change the dimming level, the signal processing unit 11 (lighting dimming) The control unit 113) changes the setting of the dimming level, and turns on the illumination load 100 at the dimming level after the change. Therefore, the lighting load 100 is not automatically turned off when the delay time has elapsed since the turning-off operation, and the lighting load 100 is turned on even after the delay time has elapsed. Setting work is not wasted, and the lighting can be turned on at the changed light control level.

Configured to adjust. In addition, when the first operation input unit 2 receives a turn-off operation while the lighting load 100 is turned on, the lighting control unit 4 turns off the lighting load 100 when a predetermined delay time has elapsed since the turning-off operation. Is provided. Then, when the second operation input unit 3 accepts the setting operation from the time of the light-off operation until the delay time elapses, the lighting control unit 4 disables the delay light-off function 116, and the light control level according to the setting operation The lighting load 100 is dimmed.

As a result, when the dimming light is turned on while waiting for the light to turn off after the light-off operation, when another operator performs a setting operation for setting the light control level, the signal processing unit 11 (lighting control unit 4) 2 The setting of the light control level is changed based on the setting operation received by the operation input unit 3. And the signal processing part 11 (lighting control part 4) invalidates the delay light extinction function by light extinction operation, and is lighting the illumination load 100 with the light control level after a change. Therefore, the lighting load 100 is not automatically turned off when the delay time elapses, and the lighting load 100 continues to be lit at the dimming level after the change even after the delay time elapses.
