The discharge lamp 101 is a light source that brightly illuminates the surroundings as main illumination, and the auxiliary lamp 102 is a light source that illuminates a light beam smaller than the main illumination as sub-illumination.

  The external switch SWE is, for example, a wall switch that turns on / off a household lighting fixture in a living room, and turns on / off the supply of power from the commercial power supply AC to the lighting device 9. When the external switch SWE is in the ON state, the voltage of the commercial power supply AC is supplied to the lighting device 9, and the operation of the first switch unit SW1 becomes valid.

Hereinafter, a description will be given based on the configuration of the lighting device 9 illustrated in FIG. 3.

FIG. 6 is a flowchart showing a lighting control method of lighting device 9 in the first embodiment.
As a lighting control method of the lighting device 9, input / output of electric power to / from the microcomputer 160, which is a feature of the first embodiment, will be described below with reference to FIG.

<S110: First switch-on process>
First, when the discharge lamp 101 is extinguished (when the lighting device 9 is off), when the drawstring 4 of the lighting fixture 1 is pulled, the first switch unit SW1 is turned on and energized, and the first power supply circuit 120 supplies the voltage from the rectifier circuit 110 to the microcomputer 160 as a power source.
Here, the first switch unit SW1 is turned on only while the drawstring 4 is pulled, and is turned off in a normal state where the drawstring 4 is released. That is, the first power supply circuit 120 supplies the voltage from the rectifier circuit 110 to the microcomputer 160 only while the drawstring 4 is being pulled.

<S120: Microcomputer startup process>
When the first power supply circuit 120 is energized, the microcomputer 160 starts up using the voltage from the first power supply circuit 120 as a power supply.

<S130: Second switch-on process>
The activated microcomputer 160 turns on the second switch circuit Q2. The second power supply circuit 130 supplies the voltage from the rectifier circuit 110 to the microcomputer 160 while the second switch circuit Q2 is on and energized. Further, when the second switch circuit Q2 is energized, the pulsating voltage from the rectifier circuit 110 is supplied to the discharge lamp 101 via the inverter circuit 13 and the like, and the discharge lamp 101 is lit.
Here, the second switch circuit Q2 is kept on until it is turned off by the microcomputer 160. That is, the microcomputer 160 is supplied with a voltage from the second power supply circuit 130 and operates until the second switch circuit Q2 is turned off. That is, even if the drawstring 4 is released and the first switch unit SW1 is turned off, the microcomputer 160 can operate.

<S140: First Switch Signal Detection Process>
The switch operation detection circuit 150 detects the operation of the user's pull string 4 with respect to the luminaire 1 based on the presence / absence of an input voltage by turning on / off the first switch unit SW1, and turns on / off the detected first switch unit SW1. The first switch signal indicating the duration and the number of times is output to the microcomputer 160.
Hereinafter, an operation on the lighting fixture 1 will be described as an operation of the first switch unit SW1.

<S150: Lighting control processing>
The microcomputer 160 that operates using the voltage from the second power supply circuit 130 as a power supply is based on the operation continuation time and the number of operations of the first switch unit SW1 indicated by the first switch signal from the switch operation detection circuit 150. The discharge lamp 101 is controlled to be turned on by controlling the inverter circuit 13 by a predetermined operation.
For example, the microcomputer 160 adjusts the dimming rate of the discharge lamp 101 step by step each time the first switch unit SW1 is operated for a short period of time (for example, an operation for turning it on for 1 second or less). Light control, continuous dimming control for continuously switching the dimming rate of the discharge lamp 101 while the first switch unit SW1 is continuously operated (operation for continuously turning on), the first switch When the unit SW1 performs a specific operation, auxiliary lamp control for turning on the auxiliary lamp 102 is performed.

<S160: Light-off control process>
When the microcomputer 160 receives the first switch signal indicating the operation of the first switch SW1 for turning off the discharge lamp 101 and the auxiliary lamp 102 from the switch operation detection circuit 150, the second switch circuit Q2 Turn off.
Thereby, the supply of voltage to the discharge lamp 101 is cut off and the discharge lamp 101 is turned off.
Further, the microcomputer 160 ends the operation because the voltage supply from the second power supply circuit 130 is lost.
That is, after the turn-off control process by the microcomputer 160 (S160), the standby power of the microcomputer 160 is approximately 0 W, and thus the power consumption of the lighting device 9 is approximately 0 W.

FIG. 7 is a functional configuration diagram of the microcomputer 160 according to the first embodiment.
A functional configuration of the microcomputer 160 according to the first embodiment will be described below with reference to FIG.

  In FIG. 7, the microcomputer 160 includes an input unit 16, a control determination unit 18, a timer unit 17, and a storage unit 19.

  The input unit 16 receives the first switch signal output from the switch operation detection circuit 150 and outputs the input first switch signal to the control determination unit 18.

The control discriminating unit 18 counts the number of times of the first switch signal input from the input unit 16 as the number of operations of the first switch unit SW1, and the timer unit according to the input of the first switch signal input from the input unit 16 17 is operated to measure the operation continuation time of the first switch unit SW1.
Further, the control determination unit 18 determines lighting control corresponding to the operation duration time and the number of operations of the first switch unit SW1 based on control information stored in the storage unit 19 in advance.
The control determination unit 18 controls the inverter circuit 13 based on the determined control information to control the lighting of the discharge lamp 101, and also controls the auxiliary lamp lighting circuit 170 to control the lighting of the auxiliary lamp 102.
In addition, the control determination unit 18 turns on the second switch circuit Q2 at the time of startup, and turns off the second switch circuit Q2 when the discharge lamp 101 and the auxiliary lamp 102 are turned off.
That is, the control determination unit 18 executes the second switch-on process (S130), the lighting control process (S150), and the extinguishing control process (S160) in the lighting control method (FIG. 6) of the lighting device 9.

  The timer unit 17 measures the operation continuation time of the first switch unit SW1 according to a command from the control determination unit 18.

  The storage unit 19 includes control information indicating lighting control corresponding to the operation duration and the number of operations of the first switch unit SW1, the number of operations of the first switch unit SW1 counted by the control determination unit 18, and the timer unit 17 The measured operation duration of the first switch unit SW1, the lighting state information of the discharge lamp 101 and the auxiliary lamp 102, and other information (for example, a flag) used for the lighting control process of the microcomputer 160 are stored.

  The input unit 16, the control determination unit 18, and the timer unit 17 are executed by the CPU. The storage unit 19 stores various information using a memory.

FIG. 8 is an example of a flowchart showing a lighting control method of microcomputer 160 in the first embodiment.
As an example of the lighting control method of the microcomputer 160 in the first embodiment, the brightness of the discharge lamp 101 every time the user pulls the pull string 4 of the lighting fixture 1 and turns on the first switch unit SW1 for a short time. , The discharge lamp 101 is turned off, or the auxiliary lamp 102 is turned on, and the user pulls the pull string 4 of the luminaire 1 for a predetermined time to change the ON state of the first switch unit SW1. A lighting control method for lighting or extinguishing the discharge lamp 101 after elapse of a certain time when it is continued will be described below with reference to FIG.

In the microcomputer 160, the user pulls the pull string 4 of the lighting device 1 to operate (switch on) the first switch unit SW <b> 1, and the input unit 16 moves from the switch operation detection circuit 150 to the first switch unit SW <b> 1. The operation is started by inputting the first switch signal indicating the ON state.
When the first switch signal is input when the discharge lamp 101 and the auxiliary lamp 102 are turned off, the control determination unit 18 of the microcomputer 160 turns on the second switch circuit Q2, and the microcomputer 160 uses the second switch circuit Q2. Operates with the voltage supplied from the second power supply circuit 130 as a power source.
Hereinafter, the first switch signal will be described as a signal indicating the ON state of the first switch unit SW1.

<S210: Initialization Processing A>
When the input unit 16 receives the first switch signal, the control determination unit 18 causes the timer unit 17 to initialize (T1 = 0) a timer T1 for measuring the operation duration time of the first switch unit SW1 (S211). ), The on / off timer flag D is initialized (D = 0) (S212).
Hereinafter, the operation continuation time of the first switch unit SW1 will be described as “switch-on continuation time”.

<S220: Switch-on measurement process A>
Next, the control determination unit 18 determines whether the input unit 16 continues to input the first switch signal, that is, whether the first switch unit SW1 continues to be on (S221: switch state determination process). A) If the first switch unit SW1 is in the ON state, the timer unit 17 causes the timer T1 to accumulate a specific integration time (for example, 100 milliseconds) (S222: timer T1 integration process A).
The timer unit 17 sets a time corresponding to the time required for the switch state determination process A (S221) and the timer integration process A (S222) as a specific integration time to be integrated in the timer T1.
The control determination unit 18 repeats the switch state determination process A (S221) and the timer integration process A (S222) until the first switch unit SW1 is turned off, and measures the switch-on duration time.

<S230: Switch-on duration determination process A>
When the off state of the first switch unit SW1 is detected in S221, the control determination unit 18 determines the switch-on duration by the timer T1 (S231, S232).

<S240: Lighting switching process A>
When the switch-on continuation time (timer T1) is short (for example, 1 second or less) in S231, the control determination unit 18 is based on the control information stored in the storage unit 19 and the lighting state information of the discharge lamp 101. The lighting state of the discharge lamp 101 is switched.
For example, the control information indicates a lighting order of “all light → light control → bean bulb → light off”. “All light” indicates a dimming rate of 100%, and “Dimming” indicates a dimming rate of 75%.
At this time, when the lighting state information of the discharge lamp 101 indicates “all light”, the control determination unit 18 turns on the discharge lamp 101 at a dimming rate of 75%, and when the lighting state information indicates “light control”. When the discharge lamp 101 is turned off and the auxiliary lamp 102 (bean bulb) is turned on. When the lighting state information indicates “bean bulb”, the auxiliary lamp 102 is also turned off, and when the lighting state information indicates “off”. Turns on the discharge lamp 101 at a dimming rate of 100%.
In addition, for example, the control information is “all light (100%) → light control A (80%) → light control B (60%) → light control C (40%) → bean bulb → light extinction”. The lighting order may be indicated by the light rate, and the control determination unit 18 may control the lighting of the discharge lamp 101 at a plurality of levels of light control.
Further, the control determination unit 18 updates the lighting state information of the discharge lamp 101 to the lighting state of the discharge lamp 101 after switching.
The control determining unit 18 turns off the second switch circuit Q2 when the lighting state information of the discharge lamp 101 is updated to “off”, that is, when both the discharge lamp 101 and the auxiliary lamp 102 are turned off, and the microcomputer In 160, the supply of voltage from the second power supply circuit 130 is cut off and the operation ends.

Here, the lighting device 9 performs the lighting switching process A for the on / off of the external switch SWE in the same manner as the lighting switching process A (S240) for the on / off of the first switch unit SW1. May be executed. That is, the lighting device 9 according to the first embodiment provides the user with a pullless operation for switching the lighting state of the discharge lamp 101 by the operation of the external switch SWE, not the operation of the pull string 4. For example, the lighting device 9 executes the lighting switching process A for the on / off of the external switch SWE as follows.
First, the external switch operation detection circuit 180 detects, as an external switch signal, switching of an external switch SWE (for example, a wall switch) that controls the supply of voltage from the commercial power supply AC to the lighting device 9.
Next, the external switch operation detection circuit 180 outputs the detected external switch signal to the switch operation detection circuit 150.
Next, the switch operation detection circuit 150 outputs an external switch signal to the microcomputer 160.
Next, the input unit 16 of the microcomputer 160 receives an external switch signal from the switch operation detection circuit 150, and outputs the input external switch signal to the control determination unit 18.
Next, the control determination unit 18 stores the time when the external switch signal is input from the input unit 16 as the time when the external switch SWE is switched from OFF to ON in the nonvolatile memory that retains the stored contents even when the power is turned off. To do.
Similarly, the time when the external switch SWE is switched from OFF to ON is also stored in the nonvolatile memory.
Then, the control determination unit 18 calculates the time from the time when the external switch SWE was switched from off to on the previous time to the time when the external switch SWE was switched from off to on this time, and the calculated time is short (for example, 1 second or less), the lighting state of the discharge lamp 101 is switched based on the control information and the lighting state information.
Here, the first switch signal and the external switch signal indicate different signal patterns and can be distinguished.

<S250: ON / OFF timer control processing>
In S232, when the switch-on continuation time (timer T1) is an intermediate time (for example, longer than 1 second and 2 seconds or less), the control determination unit 18 turns on the discharge lamp 101 after a predetermined time elapses, On / off timer control processing for turning off the discharge lamp 101 after the lamp is turned on is executed.
Here, an operation in which the user pulls the drawstring 4 for a moderate time to keep the first switch unit SW1 in the on state means activation of the on / off timer function.
Details of the on / off timer control process (S250) will be described later.

  If the switch-on continuation time (timer T1) is long (for example, longer than 2 seconds) in S232, the control determination unit 18 ends the lighting control process.

9 and 10 are flowcharts showing the on / off timer control process (S250) in the first embodiment.
The on / off timer control process (S250) executed by the control determination unit 18 of the microcomputer 160 in the first embodiment will be described with reference to FIGS.

  First, the pre-processing (S300) of the on / off timer control processing (S250) will be described with reference to FIG.

<S310: Initialization Process B>
First, the control discriminating unit 18 sets a value indicating execution of the lighting timer control or the extinguishing timer control in the lighting / extinguishing timer flag D (D = 1) (S311), and starts the lighting / extinguishing timer in the timer unit 17 The timer T2 to be used and the timer T3 used as the lighting timer or the extinguishing timer are initialized (T2 = 0, T3 = 0) (S312).
At this time, the user should be notified of the advance notice of the on / off timer control. For example, the lighting fixture body 2 is provided with an indicator such as an LED, and the control determination unit 18 lights the indicator, and lighting specified by a user's drawstring operation (for example, a switch-on operation of 1 second to 2 seconds) / Indicates that the timer function is working.

<S320: Switch-on detection process>
Next, the control determination unit 18 determines whether the input unit 16 newly inputs a first switch signal, that is, whether the first switch unit SW1 has shifted from the off state to the on state (S321).
When the ON state of the first switch unit SW1 is detected in S321, the control determination unit 18 initializes the timer T1 for measuring the switch-on duration time (T1 = 0) in the timer unit 17 (S322).

<S330: Switch-on measurement process B>
After initializing the timer T1 in S322, the control determination unit 18 determines whether the first switch unit SW1 continues to be on based on the first switch signal, similarly to the switch-on measurement process A (S220). Then, the timer unit 17 is made to integrate the timer T1 (S332).

<S340: Switch-on duration determination process B>
When the off state of the first switch unit SW1 is detected in S321, the control determination unit 18 determines the switch-on duration time by the timer T1 (S341, S342).

<S350: lighting switching process B>
When the switch-on continuation time (timer T1) is short (for example, 1 second or less) in S341, the control determination unit 18 switches the lighting state of the discharge lamp 101 as in the lighting switching process A (S240).
However, here, even when the discharge lamp 101 and the auxiliary lamp 102 are turned off, the control determination unit 18 does not turn off the second switch circuit Q2 in order to perform the on / off timer control.

<S360: ON / OFF timer release processing>
In S342, when the switch-on continuation time (timer T1) is long (for example, 3 seconds or more), the control determination unit 18 initializes the lighting / extinguishing timer flag D (D = 0) and cancels the lighting / extinguishing timer. Then, the lighting control process ends.
Here, during the on / off timer control, an operation in which the user pulls the drawstring 4 for a long time such as 3 seconds or longer to keep the first switch unit SW1 on is on / off. It means cancellation of the timer function.
At this time, in the same manner as when the lighting / extinguishing timer flag D is set (S311), for example, the control determining unit 18 may indicate to the user that the lighting / extinguishing timer function has been canceled by turning off the indicator.

<S370: ON / OFF timer standby processing>
The control determination unit 18 determines whether or not the timer T2 for starting the on / off timer indicates that a predetermined time X (for example, 3 seconds or more) has elapsed since the switch-on detection process (S320) (S371), and the predetermined time has elapsed. If not, the timer T2 is accumulated (S372), and the above processing (S320 to S360) is repeated for a predetermined time X.

  Next, the actual process (S400) of the on / off timer control process (S250) will be described with reference to FIG.

<S410: Timer Control Determination Process>
First, the control determination unit 18 determines whether the discharge lamp 101 (and the auxiliary lamp 102) is turned off based on the lighting state information of the discharge lamp 101 stored in the storage unit 19, and performs a lighting timer control and a lighting timer control. Which control is to be performed is determined.

<S420: Lighting timer control process>
When the discharge lamp 101 (and the auxiliary lamp 102) is turned off in S410, the control determination unit 18 determines whether or not the timer T3 used as the lighting timer indicates that a predetermined time (for example, 120 minutes or more) has elapsed (S421). When the predetermined time has not elapsed, the timer T3 is integrated (S422). When the predetermined time has elapsed, the discharge lamp 101 is turned on (for example, all-light lighting) (S423), and the lighting control process is terminated. .

<S430: Light-off timer control process>
When the discharge lamp 101 (or the auxiliary lamp 102) is lit in S410, the control determination unit 18 determines whether the timer T3 used as the extinguishing timer indicates that a predetermined time (for example, 60 minutes or more) has passed ( S431), when the predetermined time has not elapsed, integration of the timer T3 is performed (S432), and when the predetermined time has elapsed, the discharge lamp 101 (or auxiliary lamp 102) is turned off (S433) and the lighting control process is ended. To do.
The control determination unit 18 turns off the second switch circuit Q2, and the microcomputer 160 ends the operation.

  In FIG. 10, while the control determination unit 18 is waiting for the elapse of a predetermined time of the timer T3 (S420, S430), the first switch is the same as the processing in FIG. 9 (S320, S330, S340, S360). Control to cancel the lighting / extinguishing timer may be performed when the ON state of the unit SW1 is detected for a certain period of time.

FIG. 11 is an example of a flowchart showing a lighting control method of microcomputer 160 in the first embodiment.
As an example of the lighting control method different from the lighting control method shown in FIG. 8, while the user pulls the pull string 4 of the lighting fixture 1 and keeps the first switch unit SW <b> 1 on, the discharge lamp 101 is turned on. A lighting control method for continuously changing the brightness will be described below with reference to FIG.

<S510: Initialization Process D>
Similar to the initialization process A (S210), when the input unit 16 receives the first switch signal, the control determination unit 18 initializes the timer T1 for measuring the switch-on duration (T1 = 0). .

<S520: Switch-on duration determination processing D>
The control discriminating unit 18 determines the switch-on continuation time by the timer T1 (S521), and if the switch-on continuation time (timer T1) has not passed a predetermined time (for example, 1 second or more), based on the first switch signal It is determined whether the first switch unit SW1 continues to be on (S522), and when the first switch unit SW1 continues to be on, the timer unit 17 accumulates the timer T1 (for example, +100 milliseconds) ) (S523).

<S530: Continuous light control processing>
When the switch-on continuation time (timer T1) exceeds a predetermined time (for example, 1 second or more) in S521, the control determination unit 18 adjusts the current dimming rate and the dimming rate of the discharge lamp 101 stored in the storage unit 19. Based on the change direction of the light rate (up / down of the light control rate), the light control rate of the discharge lamp 101 is changed by a predetermined amount (for example, ± 5%), and the current emission stored in the storage unit 19 is changed. The dimming rate of the electric lamp 101 is updated to the dimming rate of the discharge lamp 101 after the change. Further, when the dimming rate of the discharge lamp 101 after the change reaches a predetermined upper limit value (for example, 90%) due to the increase in the dimming rate, the control determining unit 18 adjusts the dimming stored in the storage unit 19. When the change direction of the light rate is changed from “up” to “down” and the dimming rate is lowered, the dimming rate of the discharge lamp 101 after the change becomes a predetermined lower limit (for example, 50%). Changes the dimming rate change direction stored in the storage unit 19 from “down” to “up” (S531).
Then, the control determination unit 18 determines whether the first switch unit SW1 is kept on based on the first switch signal (S532), and while the first switch unit SW1 is kept on, The change of the dimming rate of the discharge lamp (S531) is repeated.

<S540: Lighting switching process D>
When the OFF state of the first switch unit SW1 is detected in S522, that is, when the switch-on duration (timer T1) is less than 1 second, the control determination unit 18 performs the same as in the lighting switching process A (S240). The lighting state of the discharge lamp 101 is switched.

In the description of the lighting control process of the microcomputer 160, the control determination unit 162 performs the following discharge lamp lighting control based on the first switch signal.
(1) When the first switch signal (an example of the first switch signal having the first specific pattern) is detected for a short time (for example, 1 second or less) when the auxiliary light 102 is turned on, the auxiliary light 102 is turned off. Control to turn off the second switch circuit Q2 and terminate the operation of the microcomputer 160.
(2) Control in which the dimming rate of the discharge lamp 101 is changed stepwise when a short-time first switch signal (an example of a first switch signal having a second specific pattern) is detected.
(3) When the first switch signal (an example of the first switch signal having the third specific pattern) for a short time when the discharge lamp 101 is turned on is detected, the discharge lamp 101 is turned off and the auxiliary lamp 102 is turned on. Control.
(4) A predetermined time (for example, 60 minutes) when a first switch signal (an example of a first switch signal having a fourth specific pattern) of a medium time (for example, 1 second to 2 seconds) is detected. Control for turning off the discharge lamp 101 or the auxiliary lamp 102 that is turned on after the elapse of (an example of the fourth predetermined time).
(5) A predetermined time (for example, 120 minutes) when a first switch signal (an example of a first switch signal having a fifth specific pattern) of a medium time (for example, not less than 1 second and not more than 2 seconds) is detected. Control for turning on the discharge lamp 101 that has been turned off after the elapse of (an example of the fifth predetermined time).

If it continues, the timer T is increased by 100 milliseconds (step 4). Here, the time increased in Step 4 is set to 100 milliseconds, but the time increased in Step 4 is appropriately set according to the time required for Step 2 to Step 3.

  When it is determined in step 2 that the switch SW is turned on for 1 second or longer, the dimming rate M and dimming change direction C stored in the storage unit 19 are read (step 5). The main routine 2 is entered.

(1) Main routine 101.
When the operation button 23 of the remote control transmitter 21 is pressed, a remote control signal is transmitted. When the remote control receiving circuit 28 in the receiving unit 27 of the lighting fixture 1 receives the remote control signal, the timer T of the timer unit is initialized (step 101). Then, it is determined whether or not the timer T is 1 second or longer. (Step 102)

  When the timer T is less than 1 second in step 102, it is determined whether or not the remote control signal reception state is continued (step 103). When the remote control signal reception state is continued, the timer T is increased by 100 ms (step 103). 104). Here, the time increased in step 104 is set to 100 ms, but the time increased in step 104 is appropriately set according to the time required for step 102 to step 103.

  When it is determined in step 102 that the remote control signal reception state time is 1 second or longer, the dimming rate M and dimming change direction C stored in the storage unit 19 are read (step 105), and the subroutine CHK is read. Migrate to

(2) Subroutine CHK.
After determining whether or not the dimming rate M read from the storage unit 19 is 70% or more at step 105 (step 31), the same operation as the subroutine CHK of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

(3) Subroutine REV.
The checker N is set to “0” (step 51), and the timer T of the timer unit 17 is initialized (step 52).

  It is determined whether the timer T is 0.2 seconds or longer (step 53), and when the timer T is 0.2 seconds or longer, the checker N is set to 1 and the process proceeds to the main routine 4 (step 54). Here, the checker N is set to 1 is an identification code for determining whether or not the operation of the continuous dimming is continued. In this embodiment, when the checker N is 1, the continuous dimming is performed. Indicates that the operation will continue.

  In step 53, when the timer T is less than 0.2 seconds, it is determined whether or not the remote control signal reception state is continued (step 155), and when the remote control signal reception state is continued, 100 ms is added to the timer T. (Step 56). Note that the time added in step 56 is the time required in step 53 and step 155, and is not limited to 100 ms.

  When it is determined in step 155 that the remote control signal reception has been interrupted, the timer T of the timer unit 17 is initialized (step 57), and when the timer T is 3 seconds or more, the process proceeds to the main routine 4. (Step 58).

  When it is determined at step 58 that the timer T is less than 3 seconds, it is determined whether a remote control signal is received (step 159). When no remote control signal is received, 100 ms is added to the timer T (step 159). 60). Note that the time added in step 60 is the time required in step 58 and step 159 as in step 57, and is not limited to 100 ms.

  When it is determined in step 159 that the switch SW is turned on, the checker N is set to 1 (step 61), and it is determined whether the dimming change direction C is UP (step 62).

  When it is determined in step 62 that the dimming change direction C is UP, the dimming change direction C is changed to DOWN, and the process returns to step 52 (step 63).

  When it is determined in step 62 that the dimming change direction C is DOWN, the dimming change direction C is changed to UP and the process returns to step 52 (step 64).

(4) Main routine
After the processing of the subroutine REV, the same operation as that of the main routine 4 of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

(5) Main routine
After the processing of the main routine 4, the same operation as that of the main routine 2 of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

(6) Subroutine CD1.
It is determined whether or not the dimming rate M is a preset upper limit dimming rate (step 7), and the same operation as the subroutine CD1 of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

(7) Subroutine CD2.
It is determined whether or not the dimming rate M is a preset lower limit dimming rate (step 13), and the same operation as the subroutine CD2 of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

(8) Main routine 103.
After the process of subroutine CD1 or subroutine CD2, it is determined whether or not the remote control signal reception state is continued (step 119). If the remote control signal reception state is continued, the process returns to step 6 and the remote control signal is not received. In this case, the dimming rate M and the dimming change direction C are stored in the storage unit 19 (step 120), and the process ends.

  In addition, it is difficult to set a desired brightness when the time to reach the lower limit dimming rate from the upper limit dimming rate (or the lower limit dimming rate to the upper limit dimming rate) is set to a short time, and when set to a long time It takes time to set the desired brightness.

  Therefore, the time required to reach the lower limit dimming rate from the upper limit dimming rate (or from the lower limit dimming rate to the upper limit dimming rate) is 10 seconds (dimming rate change rate 7.5% / sec) to 15 seconds (dimming control). It is desirable that the rate change rate is set to about 5% / second.

  In addition, this time is a case where the upper limit dimming rate is 100% and the lower limit dimming rate is 25%, and the range between the upper limit dimming rate and the lower limit dimming rate is narrow, for example, the upper limit dimming rate is 80% and the lower limit dimming rate. Depending on the range of the dimming rate between the upper limit dimming rate and the lower limit dimming rate, such as setting the time from the upper limit dimming rate to the lower limit dimming rate to about 5 to 8 seconds. To set as appropriate.

(9) Subroutine DIM.
When the remote control signal is not received in step 103, the same operation as the subroutine DIM of the fourth embodiment is performed. Therefore, the same reference numerals as those in the fourth embodiment are given and the description thereof is omitted.

  According to the present embodiment, as in the fourth embodiment, the brightness of the lamp 7 can be continuously adjusted and set to a desired brightness while the operation button 23 of the remote control transmitter 21 is on. The brightness at this time is stored in the storage unit 19 as the dimming rate M, and when the operation button 23 is turned on / off for a short time, the lighting state of the lamp 7 is switched from all light to dimming to extinguishing. Since the dimming lighting state can be set to the dimming rate M set by the user, the brightness according to the environment such as the size of the space used can be easily set.

  In addition, since the dimming change direction is switched according to the dimming rate of the lamp 7 that is lit, when the user wants to make the dimming rate close to the upper dimming rate and make the user dark, the brightness of the upper dimming rate is passed through. Can be set to a low dimming rate in a short period of time, and when the user wants to brighten the dimming rate close to the lower dimming rate, the user can shorten the dimming rate without going through the brightness of the lower dimming rate. A high dimming rate can be set in time.

  In addition, when the switch SW is continuously dimmed, the switch SW can be switched (reversed) by turning the switch SW off and on for a short time, so that the user's desired brightness can be set in a short time. Can do.

  Since the remote control signal from the remote control transmitter 21 may be difficult to receive due to the influence of infrared rays emitted from the fluorescent lamp, the same remote control signal is transmitted five times continuously from the remote control transmitter when the operation button is pressed once. The reception unit 27 reliably receives the data.

  In order to correspond to such a remote control transmitter, the operation of the continuous dimming flowchart is not performed with the remote control signal from the start of reception until the fifth time, and counting is performed as the continuous dimming signal from the sixth remote control signal. You may make it start. In addition, although the case where it counts as a signal of continuous light control from the 6th remote control signal has been described, it may be counted as a signal of continuous light control from the 3rd or 7th remote control signal. For example, since it takes time until the user starts continuous light control after operating the remote control transmitter, it is determined that the remote control signal is received from about 3 to 10 times and starts counting. Good.

  In the second to fifth embodiments, the case where the lamp 7 is a discharge lamp has been described. However, the brightness of an incandescent bulb or the like may be controlled by using the control method of the lighting device 9 as phase control. The brightness of the LED or the like may be controlled by controlling the current flowing in the load circuit by setting the control method of the lighting device 9 to constant current control.
