  FIG. 4 shows a control circuit for the lighting load La using the lighting control switch A (master unit) and the switch slave unit B (external switch) of the present embodiment, for example, the lighting control switch A at one end of the hallway. The switch slave unit B is installed at the other end of the hallway so that the lighting load La installed in the hallway can be turned on and off from two places. In addition, although the following description demonstrates the case where the illumination load La is a corridor lamp, the illumination load La is not limited to a corridor lamp, The installation place and application of the illumination load La are not ask | required.

  The switch slave unit B includes connection terminals ta and tb to which a series circuit of a commercial power supply AC and a lighting load La is connected via a triac 2 of the lighting control switch A, which will be described later, and a connection terminal Tc (signals) of the lighting control switch A. And a connection terminal tc connected to the input terminal). Here, the connection terminal ta and the connection terminal tb are electrically connected via an internal wiring. On the other hand, an operation switch SW for turning on / off the illumination load La is connected between the connection terminal ta and the connection terminal tc. The connection terminal ta is connected to the anode of a light emitting diode LD2 for position display. Between the cathode of the light emitting diode LD2 and the connection terminal tc, the diode D2 is forwardly connected via a current limiting resistor R5. It is connected.

  On the other hand, the lighting control switch A is connected via a pair of connection terminals Ta and Tb to which a series circuit of the commercial power supply AC and the lighting load La is connected via the switch slave B and the operation switch SW of the switch slave B. And a connection terminal Tc connected to one end of the commercial power supply AC. The illumination control switch A includes a control circuit 1 (lighting control unit) that is configured by, for example, a microcomputer and controls the entire internal circuit, a triac 2 (illumination control unit) connected between the connection terminals Ta and Tb, and a control circuit. 1, a clock circuit 3 for supplying a clock signal for operation, a clock circuit 4 for supplying a clock signal for timing to the control circuit 1, and a pushbutton switch 5 (pushing operation unit) for performing an on / off operation of the illumination load La A dimming time zone setting switch 6 (a dimming time zone setting unit) for setting a time zone (dimming time zone) for dimming and lighting the illumination load La, and a dimming lighting time for the lighting load La A brightness setting volume 7 (brightness setting unit) for setting brightness and a power supply circuit 8 for generating an operating power supply for the internal circuit from the commercial power supply AC input from the connection terminals Ta and Tb are provided.

  In the triac 2, the T2 terminal and the T1 terminal are connected to the connection terminals Ta and Tb, respectively, the gate G is connected to the connection terminal Tb via the resistor R1, and the gate G further includes an output port of the control circuit 1. PO1 is connected.

  The output port PO2 of the control circuit 1 is connected to the base of an npn transistor Tr1 through a resistor R2. The collector of the transistor Tr 1 is connected to the connection terminal Tc, and the emitter is connected to the low voltage side end of the power supply circuit 8. The collector of an npn transistor Tr2 is connected to the input port PI2 of the control circuit 1, and the emitter of the transistor Tr2 is connected to the low-voltage side end of the power supply circuit 8.

Then, current flows through the path of commercial power supply AC → light emitting diode LD2 → resistor R5 → diode D2 → transistor Tr1 → power supply circuit 8 → illumination load La → commercial power supply AC, and the light emitting diode LD2 is turned on. At this time, only a very small current flows through the light emitting diode LD2, and the illumination load La is not lit.

  The operation of the control circuit 1 taking in the operation signal of the operation switch SW provided in the switch slave unit B will be described below. In the period when the C2 side of the commercial power supply AC is positive, when the operation switch SW of the switch slave unit B is in the off state, the transistor Tr2 is on until the triac 2 is turned on. When the operation switch SW is on, the base current of the transistor Tr2 flows to the C1 side, and the transistor Tr2 is turned off. Therefore, the control circuit 1 can capture the contact signal of the operation switch SW provided in the switch slave unit B by monitoring the collector voltage of the transistor Tr2, that is, the voltage level of the input port PI2.

If the time of the timer section is shifted, such as when the time is not set, the control circuit 1 causes the light emitting diode LD1. Flashes rapidly to prompt the user to set the time.

  The control circuit 1 receives the set values of the dimming time zone setting switch 6 and the brightness setting volume 7 described above. The dimming time zone setting switch 6 is used to set a dimming time zone for dimming and lighting the illumination load La within one day, and is configured using a rotary switch in the present embodiment. The control circuit 1 monitors the setting input of the dimming time zone setting switch 6, and when the setting operation of the dimming time zone setting switch 6 is performed and the setting input changes, the time at that time is changed to the dimming time zone. In addition to setting the start time, the time width of the dimming time zone can be set every other hour from 4 to 8 hours, for example, depending on the setting position of the dimming time zone setting switch 6. Once the dimming time zone is set using the dimming time zone setting switch 6, the control circuit 1 registers the start time and time width of the dimming time zone in a built-in memory (not shown), and thereafter sets the dimming time zone in the built-in memory. When the light is turned on during the dimming time period, the illumination load La is dimmed.

  The brightness setting volume 7 is composed of a rotary variable resistor, and the dimming level of the illumination load La in the dimming time zone is, for example, in a range from 20% to 100% depending on the resistance value of the brightness setting volume 7. The light control level is set. Therefore, the brightness at the time of dimming lighting can be adjusted to a desired dimming level according to the type and application of the illumination load La to be used, and the usability is improved.

The rotary knobs 18 and 19 are arranged vertically in the center of the front surface of the cover 12 in the horizontal direction, and the light emitting diode LD1 is disposed at the left end of the front surface of the cover 12.

  Further, an operation handle 20 that pushes the push button of the push button switch 5 on the back surface according to the turning operation is attached to the front side of the body 10 so as to be able to rotate so as to cover substantially the entire front surface of the body 10. ing.

The bearing portion is provided with a biasing spring (not shown) for biasing the operation handle 20 in the counter-operation direction, and the operation handle 20 is biased counterclockwise in FIG. Thus, when a pressing force is applied to the right side portion of the operation handle 20, the operation handle 20 rotates about the shaft portion as a fulcrum, and a push button (not shown) provided on the rear surface of the operation handle 20 pushes the push button of the push button switch 5. Is pushed and the push button switch 5 is turned on. On the other hand, when the force to push the right side of the operation handle 20 is lost, the operation handle 20 receives the reaction force of the urging spring or the push button of the push button switch 5 and returns to the return position, and the push button switch 5 is turned off.

  The operation handle 20 is formed of a synthetic resin in a rectangular plate shape, and the horizontal dimension is substantially the same as the horizontal (short direction) dimension of the window hole 51 of the decorative plate 50, and the vertical dimension is the same. The size of the window hole 51 is approximately two-thirds of the vertical (longitudinal) dimension. A protrusion 21 protruding forward is formed at the left end of the front face of the operation handle 20, and opening windows 22a and 22b (operations) for exposing the rotary knobs 18 and 19 to the thin portion 25 on the right side of the protrusion 21, respectively. Hole). The operation handle 20 has a plurality of scales indicating the switching positions of the rotary knob 18 on the periphery of the opening window 22a, and letters and numbers (for example, “OFF”, indicating the time width and the operating state corresponding to each switching position. “4”, “5”... “8”, “continuous”) are displayed by printing or the like, a scale indicating the rotation range of the rotary knob 19 on the periphery of the opening window 22b, and dimming at both ends of the rotation range Characters indicating levels (20%, 100%) are displayed by printing or the like. Also, on the back of the operation handle 20, a method of using this switch, that is, a setting method using the rotary knobs 18 and 19 is displayed by printing or the like.

  Here, when the rotary knob 18 of the dimming time zone setting switch 6 is switched to the positions “4”, “5”, and “8”, the dimming time zone switches from the time when the rotary knob 18 is switched to 4 hours and 5 hours. ... set to 8 hours each. When the rotary knob 18 is switched to the “OFF” position, the illumination load La is always turned on or off regardless of the time zone, and when it is switched to the “continuous” position, the illumination load La is changed. The light is always turned on or off in a dimmed state regardless of the time zone. Further, by rotating the rotary knob 19 of the brightness setting volume 7 to a predetermined position, the dimming level of the illumination load La in the dimming time zone is set to a desired dimming level in the range of 20% to 100%. .

  Further, a through hole 24 is formed at a substantially central portion in the vertical direction of the projecting part 21, and a light guide member 23 formed of a synthetic resin having translucency is fitted into the through hole 24. The back surface of the light guide member 23 faces the light emitting diode LD1 exposed on the front surface of the cover 12, and the light of the light emitting diode LD1 is emitted to the front surface side of the operation handle 20 through the light guide member 23. .

  A handle cover 26 is attached to the operation handle 20 to cover the rotary knobs 18 and 19 exposed from the opening windows 22a and 22b of the thin portion 25 so as to be freely opened and closed. The handle cover 26 is formed so that the horizontal and vertical dimensions thereof are substantially the same as the horizontal and vertical dimensions of the thin portion 25, respectively. A pair of arms 27, 27 project from the upper and lower ends of the left side of the handle cover 26 so as to protrude sideways, and are provided on the upper and lower surfaces of the projecting portion 21 at the tip of each arm 27. A shaft 27a that is pivotally supported by a shaft hole (not shown) protrudes (see FIG. 3). Thus, by pivotally supporting the shaft 27a of each arm 27 in the shaft hole of the projecting portion 21, the handle cover 26 opens the opening windows 22a and 22b (that is, the rotary knobs 18 and 19), and the opening position. The closed position covering the windows 22a and 22b (the rotary knobs 18 and 19) can be freely selected and attached to the front face of the operation handle 20 so as to be rotatable. The handle cover 26 is held in a closed state by, for example, attracting an iron piece (not shown) held by the operation handle 20 by the magnetic force of the permanent magnet 28 attached to the back surface of the handle cover 26. The operation handle 20 and the handle cover 26 constitute a handle member 30.

  Here, when the handle cover 26 is opened, the rotary knob 18 of the dimming time zone setting switch 6 and the rotary knob 19 of the brightness setting volume 7 are exposed. The light level setting operation can be easily performed. On the other hand, the rotary knobs 18 and 19 are inadvertently operated by covering the rotary knobs 18 and 19 with the handle cover 26 except when the dimming time zone and the dimming level are set. Can be prevented from being changed. Further, when the handle cover 26 is closed, the rotary knobs 18 and 19 are covered with the handle cover 26, and the appearance of the illumination control switch A becomes the same as the appearance of other switches. In addition, since the entire front surface of the handle cover 26 becomes the operation surface, the operability can be improved by widening the operation surface. In this embodiment, the rotary knob 18 of the dimming time zone setting switch 6 is arranged on the upper side, and the rotary knob 19 of the brightness setting volume 7 is arranged on the lower side. However, the rotary knobs 18 and 19 are arranged as described above. For example, as shown in FIG. 8, the rotary knob 19 of the brightness setting volume 7 may be arranged on the upper side, and the rotary knob 18 of the dimming time zone setting switch 6 may be arranged on the lower side. Here, 52 in FIG. 8 is a blindfold plate used when the switches are not arranged in parallel.

  Next, the operation of the illumination control switch A will be described. This lighting control switch A is used, for example, to turn on or off the lighting load La installed in the corridor. In the circuit of FIG. 4, the lighting load La can be turned on / off from two places by using the switch slave unit B. It has become.

  The control circuit 1 takes in the operation inputs of the push button switch 5 and the operation switch SW of the switch slave unit B from the input ports PI1 and PI2, and the illumination load is applied by either the handle member 30 (that is, the push button switch 5) or the operation switch SW. When La is turned off, the control circuit 1 turns off the triac 2. Here, when the lighting load La is turned off, the power supply circuit 8 generates an operating power supply for the internal circuit by the voltage generated between both ends of the triac 2 due to the leakage current of the lighting load La. When the illumination load La is extinguished, the control circuit 1 turns on the light emitting diode LD1 and turns on the transistor Tr1 to turn on the light emitting diode LD2 of the switch slave unit B. The illumination control switch is activated by the light emission of the light emitting diodes LD1 and LD2. The installation positions of A and the switch slave unit B are displayed.

  On the other hand, when the lighting load La is turned on by either the pushbutton switch 5 or the operation switch SW, the control circuit 1 causes the gate G of the triac 2 at a predetermined phase angle every half cycle of the power supply voltage of the commercial power supply AC. The control signal is output to turn on the TRIAC 2, and the ON state is continued until the zero cross of the power supply voltage. Then, when the control circuit 1 repeats the above operation every half cycle of the power supply voltage, power is supplied to the lighting load La, and the lighting load La is turned on. Therefore, the control circuit 1 controls the phase angle at which the triac 2 is turned on, whereby the amount of power supplied to the illumination load La is controlled.

  Further, in the control circuit 1, the lighting load La is dimmed when an ON operation is performed in a preset dimming time zone, and if the current time is outside the dimming time zone, the lighting load The phase angle at which the TRIAC 2 is turned on is controlled so that La is fully lit. Note that there is a time lag necessary to charge the charging part of the power supply circuit 8 from the zero crossing of the AC power supply voltage to turning on the triac 2, and during this time the charging part is rapidly charged, An operating power supply for the internal circuit is obtained by the charging voltage. On the other hand, if the current time is the dimming time zone, the control circuit 1 causes the TRIAC 2 to turn on so that the lighting load La is dimmed at the dimming level set by the brightness setting volume 7. The lighting load La can be dimmed at a predetermined dimming level. Further, when the illumination load La is turned on, the light emitting diode LD1 is turned off and the transistor Tr1 is turned off to turn off the light emitting diode LD2 of the switch slave unit B.

  Here, the operation of the illumination control switch A will be described with reference to the time chart of FIG. In the time chart of FIG. 5, the dimming time zone is set between the time t4 and the time t7, and the ON operation is performed by either the push button switch 5 or the operation switch SW at the time t1 other than the dimming time zone. Then, the control circuit 1 controls the triac 2 to turn on the lighting load La, and when the off operation is performed at time t2, the triac 2 is controlled to control about 70 of the lighting level (100%) before the off operation. The lighting load La is turned on at a lighting level of% for a certain time (for example, a delay time of about 5 seconds), and then the lighting load La is turned off.

  In addition, when the ON operation is performed by either the push button switch 5 or the operation switch SW at time t3 before entering the dimming time zone, the control circuit 1 turns on the lighting load La, but the lighting load La is being turned on. At the start time t4 of the dimming time zone, the control circuit 1 controls the triac 2 to turn on the illumination load La at the dimming level L1 set by the brightness setting volume 7.

  When the off operation is performed with either the push button switch 5 or the operation switch SW at the time t5, the control circuit 1 controls the triac 2 so that the dimming is about 70% of the dimming level L1 before the off operation. After lighting the lighting load La at a level L2 for a certain period of time (for example, 5 seconds), the amount of power supplied to the lighting load La is gradually decreased over a predetermined fade time (for example, about 200 msec) to thereby reduce the lighting load La. Fade out (fade off).

  When the on operation is performed with either the push button switch 5 or the operation switch SW at the time t6 in the dimming time zone, the control circuit 1 controls the triac 2 to supply power to the illumination load La from the unlit state. The amount is gradually increased over a predetermined fade time (for example, about 200 milliseconds) to fade in the illumination load La and light at the dimming level L1 set by the brightness setting volume 7 (fade lighting). Then, at the end time t7 of the dimming time zone during the dimming lighting of the lighting load La, the control circuit 1 controls the triac 2 so that the lighting load La is fully lit (100% lighting). Further, in the control circuit 1, if the lighting load La is continuously lit for a predetermined forgetting-off time Tx (for example, 1 hour), it is determined that the lighting load La has been forgotten to turn off, and the forgetting-off time Tx has elapsed since the on operation (time t6) At time t8, the operation of turning off the lighting load La is performed, and it is possible to reliably prevent the lighting load La from being forgotten to be turned off. When it is determined that the lighting load is forgotten to turn off the lighting load La automatically, the control circuit 1 controls the triac 2 to set the lighting load La at a lighting level of about 70% of the lighting level before the lighting operation is performed. After lighting for a time (for example, about 10 seconds), the illumination load La is turned off at time t9. When the operation by the push button switch 5 or the operation switch SW is performed while the lighting level is lowered (from time t8 to time t9), the control circuit 1 does not turn off the illumination load La and turns on the lighting state. To continue.

  Further, another operation of the illumination control switch A will be described based on the time chart of FIG. In this case, the dimming time zone is set to the time zone from time t10 to t18, and if the ON operation is performed with either the push button switch 5 or the operation switch SW at time t11 in the dimming time zone, the control is performed. The circuit 1 controls the triac 2 to gradually increase the power supply amount to the lighting load La over a predetermined fade time to fade in the lighting load La, and to adjust the brightness set volume 7. Turn on at light level L3 (fade on).

  At time t12 when the illumination load La is lit, when the handle member 30, that is, the pushbutton switch 5 is continuously pressed for a predetermined on-operation time (for example, 3 seconds), the control circuit 1 controls the triac 2 to All the loads La are turned on.

  After that, when an off operation is performed with either the push button switch 5 or the operation switch SW at time t13, the control circuit 1 controls the triac 2 so that the lighting level (100%) before the off operation is about 70%. After lighting the lighting load La at a lighting level for a certain period of time, the power supply amount to the lighting load La is gradually decreased over a predetermined fade time at time t14 to fade out the lighting load La. In addition, when the adjustment value of the dimming level is changed using the brightness setting volume 7 during the dimming time period, and the ON operation is performed with either the push button switch 5 or the operation switch SW at the time t15 after the change, The control circuit 1 controls the triac 2 so that the amount of power supplied to the lighting load La is a predetermined fade time until the dimming level of the lighting load La reaches the dimming level L4 set by the brightness setting volume 7. The lighting load La is faded in (fade lighting). Then, at time t16 when the illumination load La is lit, when the off operation is performed by either the push button switch 5 or the operation switch SW, the control circuit 1 controls the triac 2 to control the light control level L4 before the off operation. After the lighting load La is turned on for a certain time (for example, 5 seconds) at a dimming level L5 of about 70% of the power, the amount of power supplied to the lighting load La is gradually decreased over a predetermined fade time at time t17. The lighting load La is faded out.

  As described above, in the illumination control switch A of the present embodiment, once the midnight zone is set as the dimming time zone by the dimming time zone setting switch 6, for example, the pushbutton switch 5 (handle member 30) is set in the dimming time zone. ) Or when any of the operation switches SW is turned on, the control circuit 1 as the lighting control unit controls the triac 2 as the lighting control unit, and the illumination load La is compared with the time zone other than the dimming time zone. Therefore, the lighting output of the illumination load La in the dimming time zone can be dimmed as compared with the normal time. Therefore, even if a user who wakes up in the bathroom at midnight turns on the lighting load La using the lighting control switch A, the user is prevented from feeling dazzled or completely waking up and falling asleep. In addition, the power consumption can be suppressed by reducing the power supply amount at midnight.

  Even in the dimming time zone, when the user presses the handle member 30 and continuously presses the push button switch 5 for a predetermined ON operation time, the control circuit 1 causes the illumination load based on the switch input from the push button switch 5. When La is fully lit and it is desired to fully illuminate the lighting load La even during the dimming time period, the lighting load La can be fully lit by a predetermined operation, which improves usability.

  Further, the control circuit 1 controls the triac 2 to turn on the lighting load La when the lighting load La is turned on and off during the dimming time period according to the switch operation of either the push button switch 5 or the operation switch SW. Since the lighting load La is faded in and out by gradually increasing or decreasing the amount of power supplied over a predetermined fade time, the user is dazzled by slowly changing the lighting output of the lighting load La. It is possible to further prevent feelings and awakening.

  When an incandescent lamp is used as the illumination load La, the bulb of the incandescent lamp is evaporated when the filament is heated to a high temperature and is generated when the filament is thinned and disconnected. In order to suppress the evaporation of the filament, Needs to lower the voltage applied to the illumination load La so that the filament temperature does not become high. In the lighting control switch A of the present embodiment, the lighting load La is dimmed during the dimming time period, and therefore, there is an effect equivalent to lowering the voltage applied to the lighting load La, and the temperature rise of the filament is increased. Suppressing and suppressing evaporation can extend the life of the incandescent lamp. FIG. 7 shows the load current that flows through the lighting load La when the lighting load La is lit. Since the incandescent lamp itself is cold at the beginning of lighting, a large current flows and then the filament temperature rises. The load current gradually decreases. If a large current flows into the lighting load La at the beginning of lighting, the filament that is thinned by this current may be broken. In this embodiment, the control circuit 1 controls the triac 2 in the dimming time zone. Since the lighting load La is ford-in, it is possible to prevent a large current from flowing into the lighting load La in the early stage of lighting and to extend the life of the lighting load La.

  The control circuit 1 may control the triac 2 to fade in and fade out the lighting load La when the lighting load La is turned on or off even in a time zone other than the dimming time zone. It is possible to prevent a large current from flowing into the lighting load La in the initial stage and extend the life of the lighting load La.

  In addition, the control circuit 1 is in the ON operation (that is, before the OFF operation) until a certain time (for example, a delay time of about 5 seconds) elapses after the OFF operation is performed by either the push button switch 5 or the operation switch SW. The lighting load La is lit at a dimming level darker than the lighting output (for example, about 70% of the dimming level before the turning-off operation), and after the user performs the turning-off operation, the user moves to another place. It is safe because the brightness up to can be secured. Further, since the lighting state of the lighting load La is maintained for a certain time after the off operation is performed, the user who performed the off operation may misunderstand that the push button switch 5 or the operation switch SW has failed to be turned off. However, since the control circuit 1 makes the lighting output of the lighting load La darker than before the turning-off operation, the user can be surely notified that the turning-off operation has been performed.

  In this embodiment, when a contact signal from the switch slave unit B is input via the connection terminal Tc as a signal input terminal, the control circuit 1 controls the triac 2 to switch on / off the lighting load La. Therefore, the lighting load La can be turned on / off from a plurality of places (two places in the present embodiment) such as a corridor or a staircase, but only the lighting control switch A without the switch slave unit B. The illumination load La may be turned on / off. In this case, a series circuit of the commercial power supply AC and the lighting load La may be connected between the connection terminals Ta and Tb. The transistor TR2 for detecting the switch input of the switch slave unit B, or the light emitting diode LD2 of the switch slave unit B The transistor TR1 for turning on or off is unnecessary.

  In this embodiment, the size of the container body 10 is formed in two module dimensions, but the size of the container body 10 is three module dimensions (three embedded wiring devices of unit dimensions are arranged in the short width direction). The internal space can be made larger than when two modules are used, so the power required for increasing the number of parts by adding functions and increasing the capacity of the lighting load La It is possible to easily cope with an increase in the size of the control element (triac 2).

  Further, as shown in FIGS. 10A and 10B, the handle member 30 described in the first embodiment (consisting of the operation handle 20 and the handle cover 26) is provided on the front side of the body 10. It is pivotally attached so as to cover the whole. The handle member 30 is formed so that the horizontal dimension is substantially the same as the horizontal (short direction) dimension of the window hole 51 of the decorative plate 50, and the vertical dimension is the vertical direction (longitudinal direction) of the window hole 51.

The common components are denoted by the same reference numerals and the description thereof is omitted.

  Next, the operation of this embodiment will be described. This lighting control switch A is used, for example, to control on / off of a lighting load La and a ventilation fan F installed in a toilet.

  The control circuit 1 takes in the operation input of the pushbutton switch 5 from the input port PI1, and when the illumination load La is turned off by pushing the handle member 30 (that is, the pushbutton switch 5), the control circuit 1 The triac 2 is turned off, the energization to the exciting coil 32a is stopped, and the relay contact 32b is turned off. When the illumination load La is turned off, the control circuit 1 turns on the light emitting diode LD1, and displays the installation position of the illumination control switch A by the light emission of the light emitting diode LD1. Note that the control circuit 1 may continue the ON state of the relay contact 32b until the predetermined operation holding time has elapsed from the OFF operation, and extend the operation of the ventilation fan F by the operation holding time.

  On the other hand, when the lighting load La is turned on by pushing the handle member 30 (push button switch 5), the control circuit 1 causes the triac 2 to be used at a predetermined phase angle every half cycle of the power source voltage of the commercial power source AC. The control signal is output to the gate G of the power supply, and the triac 2 is turned on, and the on state is continued until the zero cross of the power supply voltage. Then, when the control circuit 1 repeats the above operation every half cycle of the power supply voltage, power is supplied to the lighting load La, and the lighting load La is turned on. Therefore, the control circuit 1 controls the phase angle at which the triac 2 is turned on, whereby the amount of power supplied to the illumination load La is controlled. At the same time, the control circuit 1 supplies an excitation current to the excitation coil 32a to make the relay contact 32b conductive, supplies power to the ventilation fan F, and turns on the ventilation fan F. The control circuit 1 turns on the TRIAC 2 so that the lighting load La is dimmed at the dimming level set by the brightness setting volume 7 when the ON operation is performed during the preset dimming time period. The phase angle for turning on the triac 2 is controlled so that the lighting load La is fully lit when the on operation is performed outside the dimming time zone.

  Here, the operation of the illumination control switch A will be described with reference to the time chart of FIG. 11A shows the lighting state of the illumination load La, and FIG. 11B shows the operating state of the ventilation fan F. In the time chart of FIG. 11, the dimming time zone is set between the time t25 and the time t31, and when the on operation by the handle member 30 (the push button switch 5) is performed at the time t20 other than the dimming time zone, The control circuit 1 controls the phase angle of the triac 2 so that the amount of power supplied to the lighting load La is gradually increased over a predetermined fade time dT1 (for example, 0.5 seconds), and all the lights are turned on ( Fade lighting), an exciting current is supplied to the exciting coil 32a to turn on the relay contact 32b, and the ventilation fan F is turned on. Thereafter, when the turning-off operation is performed at time t21, the control circuit 1 controls the triac 2 so that the lighting load La is set at a lighting level about 50% of the lighting level (100%) before the turning-off operation for a certain time dT2 (for example, After turning on the lighting load La, the amount of power supplied to the lighting load La is gradually decreased over a predetermined fade time dT3 (for example, 3 seconds) to fade out the lighting load La (fade off). . Further, the control circuit 1 keeps the ventilation fan F on even after the off operation, and at the time t24 when the delay time dT4 (operation holding time) set by the delay time setting unit 9 has elapsed since the off operation, the excitation coil 32a. The ventilation fan F is stopped by stopping energization to turn off the relay contact 32b.

  In addition, when an ON operation is performed by the handle member 30 (push button switch 5) at time t26 after entering the dimming time zone, the control circuit 1 controls the phase angle of the triac 2 to apply to the illumination load La. By gradually increasing the power supply amount over a predetermined fade time dT1, the illumination load La is turned on at the dimming level L6 set by the brightness setting volume 7 (fade lighting), and the excitation coil 32a is excited. A current is passed to turn on the relay contact 32b, and the ventilation fan F is turned on. Thereafter, when the turning-off operation is performed at time t27, the control circuit 1 controls the triac 2 to turn on the lighting load La for a certain time dT2 at a dimming level L7 that is about 50% of the dimming level L6 before the turning-off operation. Then, the illumination load La is faded out (fade off) by gradually decreasing the power supply amount to the illumination load La over a predetermined fade time dT3. Further, the control circuit 1 keeps the ventilation fan F on even after the turning-off operation, and stops energization to the exciting coil 32a and turns off the relay contact 32b at time t30 when the delay time dT4 has elapsed since the turning-off operation. Then, the ventilation fan F is stopped.

  Further, when an ON operation is performed by the handle member 30 (push button switch 5) at time t32 after the dimming time period ends, the control circuit 1 controls the phase angle of the triac 2 to control the power to the illumination load La. The supply amount is gradually increased over the fade time dT1 to fully light (fade lighting), and an exciting current is supplied to the exciting coil 32a to turn on the relay contact 32b, and the ventilation fan F is turned on. Thereafter, when the turning-off operation is performed at time t33, the control circuit 1 controls the triac 2 to turn on the lighting load La for a certain time dT2 at a lighting level of about 50% of the lighting level (100%) before the turning-off operation. Then, the illumination load La is faded out (fade off) by gradually decreasing the power supply amount to the illumination load La over a predetermined fade time dT3. Further, the control circuit 1 keeps the ventilation fan F on after the turning-off operation, and stops energization to the exciting coil 32a and turns off the relay contact 32b at time t36 when the delay time dT4 has elapsed since the turning-off operation. Then, the ventilation fan F is stopped.

  As described above, in this embodiment, the control circuit 1 turns on and off the lighting load La and the ventilation fan F in accordance with the on / off operation of the handle member 30 (that is, the push button switch 5). In a place where both the illumination load La and the ventilation fan F are installed, both the illumination load La and the ventilation fan F can be turned on / off in conjunction with only one handle member 30 operation, and the usability is improved. There is an effect. Further, in the control circuit 1, since the operation time is extended by a predetermined delay time dT4 even after the turning-off operation by the handle member 30 (that is, the push button switch 5), in the case of the ventilation fan F installed in the toilet, the bathroom is deodorized. In the case of the ventilation fan F installed in, a delayed stop function for extending the operation time for drying can be added. Similarly to the first embodiment, when the ON operation is performed in the dimming time zone, the control circuit 1 lights the illumination load La at the dimming level set by the brightness setting volume 7, so that the dimming time If, for example, a midnight time zone is set as the band, the control circuit 1 automatically reduces the lighting output of the lighting load La when the lighting load La is turned on at midnight, so that the user feels dazzling, It is possible to prevent awakening and becoming difficult to fall asleep.
