  Embodiments according to the present invention will be described below with reference to the drawings. In addition, the structure which attached | subjected the same code | symbol in each figure shows that it is the same structure, The description is abbreviate | omitted.

(First embodiment)
FIG. 1 is an external view showing an example of a configuration of an illumination system according to an embodiment of the present invention. FIG. 2 is a block diagram showing an example of the configuration of the illumination system shown in FIG. A lighting system 1 shown in FIG. 1 includes a lighting device 2 and a remote control device 3. The illuminating device 2 includes a substantially disc-shaped housing 4, a lighting circuit 5 that is an example of a light emitting unit, a control block 6, and a power supply circuit unit 21 that is an example of a power acquisition unit. The casing 4 is provided with a lighting circuit 5, a control block 6, and a power supply circuit unit 21. And the discharge lamp 7 which is an example of a light emitting member, and the auxiliary illumination 8 which consists of LED (Light Emitting Diode), a miniature light bulb, etc. are connectable with the lighting circuit 5 by the connection connector which is not illustrated. Instead of the discharge lamp 7, a light emitting member such as an incandescent bulb, a krypton bulb, or a halogen bulb may be used.

  The power supply circuit unit 21 is supplied with power from, for example, a commercial AC power supply connected to the outside, and supplies the power to the lighting circuit 5 to acquire the power and turn on the discharge lamp 7 and the auxiliary illumination 8. The power supply voltage for operation of the block 6 is supplied. The lighting circuit 5 is a circuit unit that supplies power to the discharge lamp 7 and the auxiliary illumination 8 to emit light or change brightness according to a dimming signal SC from the control block 6, for example, an inverter circuit. It is constituted by.

  The control block 6 includes, for example, a receiving unit 601 that is an example of a signal receiving unit that receives a communication signal transmitted from the remote control device 3 through infrared communication, for example, wireless communication. For example, a wake-up program for causing the lighting circuit 5 to perform a light emitting operation so that the user can wake up comfortably, for example, is configured using a transmission unit 602 that transmits a signal and a nonvolatile storage element such as a ROM (Read Only Memory). A program storage unit 603 that stores a plurality of lighting control programs in advance, such as a relaxation program that controls the light emission intensity so that the user can relax, and a volatile storage element such as a RAM (Random Access Memory), for example, A setting storage unit 604 that stores setting instruction information received by the receiving unit 601; for example, an RTC (Real Ti me clock) or a radio clock, a lighting control unit 606 as an example of a light emission control unit, and a voice synthesis circuit that outputs a voice signal in accordance with a control signal from the lighting control unit 606 607, a speaker 608 that emits a sound in response to a sound signal from the sound synthesis circuit 607, and a switch unit 609 that receives an operation input by the user.

  The illumination control unit 606 is configured using, for example, a CPU (Central Processing Unit), and executes a control program read from the program storage unit 603 based on setting instruction information received by the reception unit 601. It functions as a notification processing unit 610, a turn-off processing unit 611, and a lighting processing unit 612. The control unit 606 is connected to an oscillator 613 that supplies a clock signal for operating the control unit 606.

  The remote control device 3 includes an operation unit 301 configured by, for example, a push button switch, a display unit 302 configured by, for example, a liquid crystal display device, and a storage unit 303 configured by, for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory). For example, a remote control control unit 304 configured using a CPU, a remote control transmission unit 305 that transmits a control signal from the remote control control unit 304 to the lighting device 2 through infrared communication, for example, by emitting an infrared LED, and the lighting device 2 A remote control receiving unit 306 that receives a transmitted communication signal by, for example, infrared communication. The operation unit 301 includes a setting confirmation instruction button 307 and a setting cancellation instruction button 308. The setting cancellation instruction button 308 includes a plurality of, for example, two push button switches. Then, remote control control unit 304 causes setting instruction information received by operation unit 301 to be transmitted from remote control transmission unit 305 and causes display unit 302 to display information received by remote control reception unit 306.

  Further, the operation unit 301 receives a setting confirmation instruction for requesting confirmation of the setting instruction information set in the lighting device 2, and the remote controller control unit 304 sets a setting confirmation instruction signal representing the setting confirmation instruction received by the operation unit 301. Is transmitted from the remote control transmission unit 305, and the information received by the remote control reception unit 306 is displayed on the display unit 302.

  Furthermore, the operation unit 301 in the remote control device 3 further receives an operation instruction (second setting instruction) indicating that the discharge lamp 7 emits light in a fully lit state, an operation instruction for requesting the discharge lamp 7 to be turned off, and the like. The remote controller control unit 304 causes the lighting device 2 to perform an operation according to the operation instruction by transmitting a control signal (second setting signal) representing the operation instruction received by the operation unit 301 from the remote control transmission unit 305. It is like that.

  Next, operation | movement of the illumination system 1 comprised as mentioned above is demonstrated. FIG. 3 is a flowchart showing an example of the operation of the illumination system 1 shown in FIG. Moreover, FIG. 4 is explanatory drawing for demonstrating an example of operation | movement of the illumination system 1 shown in FIG.

  First, an input of a setting instruction (first setting instruction) by the user is accepted by the operation unit 301 in the remote control device 3 (step S1). Specifically, an operation input for selecting a predetermined lighting control program for causing the lighting device 2 to perform a control operation corresponding to the setting of the wake-up time and the first light emission control, for example, by the operation unit 301, for example, wake-up An operation input for selecting a program is received, and the remote controller control unit 304 stores the received wake-up time, for example, start time information indicating 7 o'clock and information indicating the wake-up program as setting instruction information. (Step S2), and a setting signal (first setting signal) containing the setting instruction information is transmitted from the remote control transmission unit 305 to the reception unit 601 (step S3).

  For example, when 7:00 is set as the wake-up time, the remote controller control unit 304 causes the lighting control unit 606 in the lighting device 2 to start the lighting control operation from 30 minutes before the wake-up time. 6:30 may be used as start time information. Further, the remote control control unit 304 has shown an example in which the start time information and the information indicating the wake-up program are accommodated in the setting signal and transmitted from the remote control transmission unit 305 at the same time. When received, a setting signal containing start time information is transmitted from the remote control transmission unit 305 to the reception unit 601, and when an operation input for selecting a wakeup program is received, a setting containing information indicating the wakeup program The signal may be transmitted from the remote control transmission unit 305 to the reception unit 601.

  In addition, it is highly possible that the user sets the next day's wake-up time using the remote control device 3 before going to bed. Therefore, it is assumed that the user performs a setting input operation using the remote control device 3 before going to bed, and the remote control unit 304 sends an instruction command to another device that is appropriate to be operated at bed time in step S3. You may make it transmit simultaneously to another apparatus. Examples of other devices that are appropriate to be operated at bedtime include electronic locks for entrance doors, entrance lights, crime prevention devices, and other home appliances.

  In this case, for example, when an input of a setting instruction by the user is received by the operation unit 301, in step S3, the remote control transmission unit 305 transfers to the reception unit 601 in accordance with a control signal from the remote control control unit 304. An instruction command for instructing “locking” for an electronic lock, “turning off” for an entrance light, “starting a security operation” for a security device, “power off” for other home appliances, etc. is transmitted. You may make it do. Thereby, since the user can perform the operation instruction with respect to the device suitable for sleeping at the same time by performing the setting input operation using the remote control device 3, the convenience is improved.

  Next, the receiving unit 601 in the lighting device 2 receives the setting signal from the remote control transmission unit 305 (step S4), and the lighting control unit 606 sets and stores the setting instruction information contained in the received setting signal. Stored in the unit 604 (step S5). Then, the notification processing unit 610 transmits the setting instruction information stored in the setting storage unit 604 from the transmission unit 602 to the remote control reception unit 306 (step S6), while the notification processing unit 610 converts the setting instruction information into voice synthesis. The content of the setting instruction information is notified by voice, for example, “The wake-up program has been set at 6:30” by the speaker 608 according to the signal output to the circuit 607 and output from the voice synthesis circuit 607. (Step S7).

  In step S7, the notification processing unit 610 controls the amount of power supplied from the lighting circuit 5 to the discharge lamp 7 to blink the discharge lamp 7 or visually recognize the dimming level of the discharge lamp 7, for example. You may make it alert | report that the setting instruction | indication information was set by changing as short as possible. When changing the dimming level of the discharge lamp 7, for example, if the current dimming level is 50% or more, the dimming level may be set near the dimming lower limit or turned off, and the current dimming level is 50% or less. If so, the dimming level may be set near the rated lighting or off.

  Further, in step S7, the notification processing unit 610 notifies the contents of the set setting instruction information, for example, the set program type and start time information, according to the number of times the discharge lamp 7 blinks or the number of changes in the dimming level. May be. Specifically, for example, when 7:00 is set as the start time information, the notification processing unit 610 may blink the discharge lamp 7 seven times or change the dimming level of the discharge lamp 7 seven times. .

  Further, the notification processing unit 610 may notify the contents of the set setting instruction information based on the number of buzzer sounds by using a buzzer instead of the voice synthesis circuit 607 and the speaker 608.

  Thereby, the user can notify that the setting instruction information is set in the lighting device 2 or the contents of the set setting instruction information by voice notification information, blinking of the discharge lamp 7, a change in dimming level, or a buzzer sound. Can be confirmed.

  On the other hand, the remote control receiving unit 306 in the remote control device 3 receives the setting instruction information from the transmission unit 602 (step S8), and the remote control control unit 304 includes the contents of the received setting instruction information, for example, the set program. The type and start time information are displayed on the display unit 302 (step S9).

  Thereby, the user can confirm the content of the setting instruction information set in the lighting device 2 by the display on the display unit 302. In step S9, the remote controller control unit 304 may add 30 minutes to the start time information, for example, information indicating 6:30, and display the wake-up time set by the user at 7 o'clock. .

  On the other hand, in step S <b> 10, the extinguishing control unit 611 controls the extinguishing of the discharge lamp 7. Specifically, as shown in FIG. 4, the turn-off process indicates that the time T1 after a predetermined time t1 has elapsed from the set time T0 when the setting signal is received by the receiving unit 601 in step S1. The clock unit 605 is referred to and detected by the unit 611. Then, the power supply from the lighting circuit 5 to the discharge lamp 7 is stopped according to the control signal from the turn-off processing unit 611, and the discharge lamp 7 is turned off at time T1.

  In this case, since it is highly likely that the user inputs a setting instruction using the remote control device 3 immediately before going to bed, the receiving unit 601 turns off the discharge lamp 7 after the time t1 has elapsed from the set time T0, thereby providing illumination. Forgetting to turn off can be reduced. The operation unit 301 in the remote control device 3 receives a setting input of the time T1 by the user, and a setting signal including information indicating the time T1 received by the operation unit 301 is received from the remote control transmission unit 305 in the illumination device 2. The discharge lamp 7 may be configured to be turned off based on the time T1 included in the setting signal transmitted to the unit 601 and received by the receiving unit 601 by the turn-off processing unit 611. Thereby, the user can set the time T1 of the discharge lamp 7 using the remote control device 3.

  In the above-described configuration in which the user sets the time T1, the remote control device 3 includes, for example, an unillustrated clock unit that counts the current time, and the remote control unit 304 sets the time T1 set by the user and the unillustrated clock unit. The difference from the current time obtained by the clock is calculated as a predetermined time t1, and a setting signal including information indicating the calculated time t1 is transmitted from the remote control transmission unit 305 to the reception unit 601 in the lighting device 2. The time t1 included in the setting signal received by the receiving unit 601 by the turn-off processing unit 611 is timed by a timer (not shown), so that the discharge lamp 7 is turned off after the time t1 has elapsed from the set time T0. Also good.

  Further, as shown in FIG. 5, the turn-off processing unit 611 turns off the discharge lamp 7 at time T <b> 1 and turns on the auxiliary illumination 8 instead, thereby dimming the illumination. Further, for example, a predetermined predetermined value is set. The auxiliary illumination 8 may be turned off after the time t2. Alternatively, as shown in FIG. 6, at time T1, the discharge lamp 7 is dimmed to illuminance 2 that is darker than illuminance 1 at the set time T0, and the discharge lamp 7 is dimmed. The discharge lamp 7 may be turned off after a predetermined time t2 has elapsed. In this case, the illuminance 2 may be configured to be settable by the user.

  Thereby, since the illumination illumination intensity of a user's sleeping edge can be made into a dimming state, the user's comfort that it cannot sleep in the dark, for example can be improved.

  In addition, as shown in FIG. 7, the dimming processing unit 611 gradually adjusts light from illuminance 1 at the set time T0 so that the discharge lamp 7 is turned off after a predetermined time t1 preset from the set time T0. The discharge lamp 7 may be dimmed and extinguished by the dimming sweep dimming. In this case, the configuration may be such that the auxiliary illumination 8 is turned on after the elapse of time t1, or the illuminance 2 is maintained without turning off the discharge lamp 7. Further, during the dimming sweep, the melody voice signal may be output from the voice synthesis circuit 607 to the speaker 608 in accordance with the control signal from the extinguishing processing unit 611, and the melody may flow from the speaker 608.

  Further, as shown in FIG. 8, the extinguishing processing unit 611 reduces the discharge lamp 7 to illuminance 2 by the dimming sweep dimming from the set time T0, and then time T2 after elapse of a preset time t2. The structure which maintains the discharge lamp 7 with the illumination intensity 2 may be sufficient. In this case, instead of maintaining the discharge lamp 7 at the illuminance 2, the auxiliary illumination 8 may be turned on.

  Thereby, since illumination intensity can be reduced gradually, a user can relax and go to bed. Further, if the user can set the times t1 and t2, the discharge lamp 7 can be dimmed and turned off at the time when the user wants to go to bed, and further, the continuous lighting of the discharge lamp 7 and the like while sleeping can be suppressed. Power consumption can be reduced. Furthermore, the melody flows during the dimming sweep period, so that the user can sleep while relaxing.

  Next, in step S11, the lighting processing unit 612 refers to the start time information stored as setting instruction information in the setting storage unit 604 and the current time obtained by the clock unit 605, and the current time is the start time information. When the start time T3 shown in FIG. 5 is reached (YES in step S11), the lighting processing unit 612 reads information indicating the wake-up program stored as setting instruction information in the setting storage unit 604, and the lighting processing unit 612 stores the program. The wake-up program stored in the unit 603 is executed (step S12).

  Then, as shown in FIGS. 4 to 8, when the wake-up program is executed by the lighting processing unit 612, the start time T 3, that is, the start time stored as setting instruction information in the setting storage unit 604 is 6 o'clock. The illuminance of the discharge lamp 7 is gradually increased from 30 minutes, and the discharge lamp 7 is fully lit at time T4, that is, 7:00, which is the wake-up time set by the user.

  Accordingly, at the start time T3, the lighting processing unit 612 starts to execute the wake-up program based on the setting instruction information stored in the setting storage unit 604 and the current time obtained by the clock unit 605. Therefore, communication from the remote control device 3 to the lighting device 2 cannot be performed, for example, when the user falls the remote control device 3 while sleeping, changes the position or orientation, or covers the futon. Also, lighting control based on the wake-up program can be started at the start time T3 indicated by the start time information stored as setting instruction information in the setting storage unit 604.

  Note that the setting storage unit 604 may be configured to store a plurality of setting instruction information. For example, as shown in FIG. 9, at time T0, after “start time T3” and “wake-up program” are set as setting instruction information by the processing of steps S1 to S5, at time T10, steps S1 to S5 and Similarly, for example, a “relaxation program” which is an illumination control program for periodically changing the light output level of the discharge lamp 7 for the purpose of relaxing the user, and a relaxation program are called “start time T11”, eg, afternoon When the start time information indicating that it starts at 3 o'clock is stored as the setting instruction information, the lighting processing unit 612 starts the “wake-up program” at the start time T3 and the “relaxation program” at the start time T11. You may do it.

  In this case, at the start time T3 and the start time T11, the lighting processing unit 612 determines the “wake-up program” based on the setting instruction information stored in the setting storage unit 604 and the current time obtained by the clock unit 605, respectively. Since the execution of the “relaxation program” can be started, even if the remote control device 3 cannot communicate with the lighting device 2 at the start time T3 and the start time T11, the setting storage unit 604 stores the setting instruction information. Lighting control based on the “wake-up program” and the “relaxation program” can be started at the times indicated by the stored start time information.

  The setting storage unit 604 is configured to store setting on / off information indicating whether the associated setting instruction information is valid or invalid in association with the setting instruction information, and the lighting processing unit 612 includes: For the setting instruction information associated with the setting on / off information indicating validity, the lighting control operation in steps S11 and S12 is performed, while for the setting instruction information associated with the setting on / off information indicating invalidity, step S11 is performed. , S12 may not be executed.

  Then, the remote control device 3 provides a setting-on instruction for validating the setting instruction information stored in the setting storage unit 604 and a setting-off instruction for invalidating the setting instruction information stored in the setting storage unit 604. The remote controller control unit 304 transmits the received setting ON instruction or setting OFF instruction from the remote controller transmission unit 305 to the reception unit 601, and the illumination control unit 606 receives the setting ON instruction from the reception unit 601. The setting on / off information of the setting instruction information stored in the setting storage unit 604 is validated when the setting is received, and the setting instruction information stored in the setting storage unit 604 is received when the receiving unit 601 receives the setting off instruction. The setting on / off information may be invalidated. The lighting control unit 606 may invalidate the setting on / off information of the setting instruction information after a lighting process based on the setting instruction information, for example, a wake-up program is executed.

  Thus, the user performs setting operation of the setting instruction information in advance, and when the user wants to actually use the function set by the user, by using the remote control device 3 to transmit the setting on instruction to the lighting device 2 in advance. Since the set operation can be performed, the convenience can be improved. For example, even when the user operates the lighting device 2 with the same setting every day, the setting is made in advance by simply transmitting a setting-on instruction to the lighting device 2 using the remote control device 3 without repeating the same setting operation every time. Since the operation can be performed by the lighting device 2, the convenience is improved.

  The setting storage unit 604 stores a plurality of setting instruction information, and stores setting on / off information indicating whether the corresponding setting instruction information is valid or invalid in association with each setting instruction information. The remote control device 3 receives an input of a setting on instruction and a setting off instruction relating to each setting instruction information stored in the setting storage unit 604, and sets the received setting on instruction or setting off instruction. The information is transmitted from the remote control transmission unit 305 to the reception unit 601 as information, and the illumination control unit 606 validates the setting on / off information received by the reception unit 601 as the setting on / off information of the corresponding setting instruction information, or It may be invalidated.

  As a result, the user can select a plurality of setting instruction information by setting on instruction and setting off instruction, so that convenience can be improved.

  In addition, the switch unit 609 accepts input of setting on / off information from the user, and the lighting control unit 606 sets the setting instruction information corresponding to the setting on instruction and the setting off instruction received by the receiving unit 601. Information may be validated or invalidated. Thus, even when the remote controller 3 cannot be transmitted to the lighting device 2 using the remote controller 3, such as when the remote controller 3 is lost or broken, the user can use the switch unit 609. Setting on / off information can be set in the setting storage unit 604.

  Further, the switch that receives the setting input of the setting on / off information is, for example, a channel setting switch (not shown) for setting a channel of infrared communication performed between the remote control transmission unit 305 and the reception unit 601, or the illumination control unit 606. A configuration may be adopted in which input of setting on / off information is accepted by a combination of these switch operations using a reset switch (not shown) that initializes the operation. For example, when the channel setting switch (not shown) and the reset switch (not shown) are turned on at the same time, or after the channel setting switch (not shown) has been turned on for a predetermined time, for example, for about 5 seconds, the reset switch is turned on. In such a case, a setting input of setting on / off information may be accepted. As a result, there is no need to provide a switch unit 609 dedicated to setting on / off information setting input, and the cost of the switch can be reduced.

  Next, with reference to the flowchart shown in FIG. 10, an operation when a setting confirmation instruction is received by the remote control unit 304 will be described. For example, when the user confirms the content of the setting instruction information set in the lighting device 2 between the setting time T0 and the start time T3 in FIG. 4, the setting confirmation instruction button is operated by the operation unit 301 in the remote control device 3. 307 is detected, a setting confirmation instruction from the user is accepted (step S21), and a setting confirmation instruction signal accommodating the setting confirmation instruction is transmitted from the remote control transmission unit 305 to the reception unit 601 (step S21). S22).

  Next, when the receiving unit 601 in the lighting device 2 receives the setting confirmation instruction signal from the remote control transmitting unit 305 (step S23), the receiving unit 601 stores the setting in the setting storage unit 604 according to the control signal from the lighting control unit 606. The setting instruction information being transmitted is transmitted from the transmission unit 602 to the remote control reception unit 306 (step S24), while the notification processing unit 610 outputs the setting instruction information to the voice synthesis circuit 607 and is output from the voice synthesis circuit 607. In response to the received signal, the speaker 608 notifies the contents of the setting instruction information by voice, for example, “Wake-up program is set at 6:30” (step S25).

  Further, when a plurality of setting instruction information is stored in the setting storage unit 604, for example, “The wake-up program is set at 6:30. The relaxation program is set at 3:00 pm”. In addition, the contents of the plurality of setting instruction information may be notified by voice. Thus, for example, even when the user has set a plurality of programs and forgets which program is set at what time, the set time of each program can be confirmed.

  Note that the notification processing unit 610 controls the amount of power supplied from the lighting circuit 5 to the discharge lamp 7 in step S25, for example, as in step S7 shown in FIG. The setting content of the setting instruction information may be notified by, for example, changing the light control level of 7 for a short period of time that can be visually recognized.

  In step S22, a current time confirmation instruction for requesting confirmation of the current time measured by the clock unit 605 is transmitted from the remote control device 3 to the lighting device 2 instead of the setting confirmation instruction. In step S25, for example, notification is made. The processing unit 610 outputs the current time information read from the clock unit 605 to the speech synthesis circuit 607, and the speaker 608 responds to the signal output from the speech synthesis circuit 607, for example, “It is now 12:30. As described above, the current time of the clock unit 605 may be notified by voice. Thereby, the user can know the current time by voice and can check the time counted by the clock unit 605, so that convenience is improved.

  Hereinafter, the operation of the remote control device 3 in steps S26 and S27 is the same as that in steps S8 and S9 shown in FIG.

  Next, with reference to the flowchart shown in FIG. 11, an operation for canceling the setting instruction set in the remote control device 3 will be described. For example, in FIG. 4, when the user cancels the setting instruction set in the lighting device 2 between the setting time T0 and the start time T3, the setting cancel instruction button 308 is set to 2 by the operation unit 301 in the remote control device 3. By detecting that both have been simultaneously pressed, a setting cancellation instruction from the user is accepted (step S31), and a setting cancellation instruction signal accommodating the setting cancellation instruction is transmitted from the remote control transmission unit 305 to the reception unit 601. (Step S32).

  In this case, if the user does not simultaneously press a plurality of, for example, both of the setting cancellation instruction buttons 308, the setting cancellation instruction is not accepted. Therefore, the user cancels the setting instruction erroneously set in the lighting device 2 due to an erroneous operation. Can be suppressed.

  Next, when the receiving unit 601 in the lighting device 2 receives the setting cancellation instruction signal from the remote control transmission unit 305 (step S33), the notification processing unit 610 stores the setting instruction information stored in the setting storage unit 604. Is output to the speech synthesis circuit 607, and the setting cancellation is performed by the speaker 608 in response to the signal output from the speech synthesis circuit 607, for example, "Are you sure you want to cancel the wake-up program?" A confirmation message is notified by voice (step S34).

  Then, in the remote control device 3, the setting release instruction from the user is accepted and the setting release instruction signal is transmitted again by the processing in steps S <b> 31 and S <b> 32. When the cancellation instruction signal is received (YES in step S35), the notification processing unit 610 outputs a control signal based on the setting instruction information stored in the setting storage unit 604 to the voice synthesis circuit 607, and the voice synthesis circuit 607. In response to the signal output from the speaker 608, a confirmation message for canceling the setting is notified by voice, for example, “The wake-up program set at 7 o'clock has been canceled” (step S36), and the lighting control unit 606 Deletes the setting instruction information stored in the setting storage unit 604. Set by the instruction is canceled (step S37).

  Accordingly, since the setting instruction content to be canceled is notified by voice, the user can confirm the setting instruction content to be canceled, and the setting is prevented from being erroneously canceled. In addition, since the setting instruction is not canceled unless the user performs the setting cancellation instruction operation twice, it is possible to prevent the setting instruction from being erroneously canceled even if the setting cancellation instruction operation is erroneously performed once. can do.

  Note that the notification processing unit 610 controls the power supply amount from the lighting circuit 5 to the discharge lamp 7 to blink the discharge lamp 7 in steps S34 and S36, as in step S7 shown in FIG. You may make it alert | report the setting content of setting instruction information by changing the light control level of the discharge lamp 7 for a short period of time which can be visually recognized. Moreover, the illumination control part 606 is good also as a structure which transfers to step S36 and cancels | releases a setting instruction | indication after step S33, without performing the process of step S34, S35.

  The remote control device 3 further includes a remote control clock unit (not shown) that measures the current time, and when an operation instruction is transmitted from the remote control device 3 to the illumination system 1, for example, a setting signal, a setting confirmation instruction signal, a setting In addition to a release instruction signal, setting on / off information, and the like, when a control signal for instructing full lighting, dimming lighting, and the like of the discharge lamp 7 is transmitted, the remote control device 3 and the remote control side clock unit (not shown) together with these instruction signals The current time information obtained in the above is transmitted, and the illumination control unit 606 may reset the current time of the clock unit 605 based on the current time information received when these instruction signals are received.

  For example, when the lighting device 2 is attached to an indoor ceiling, a commercial power supply voltage is often supplied via a wall switch attached to a wall surface of a building. When the switch is turned off, no power is supplied to the lighting device 2, so that the clock unit 605 has a battery for operating the clock unit 605 or the wall switch is turned on in order to keep the time counting. Therefore, it is necessary to provide a radio timepiece that can adjust the time of the timepiece unit 605 when the supply is started, and there is a disadvantage that the cost increases.

  However, as described above, if any operation instruction is transmitted from the remote control device 3 to the lighting system 1, the current time of the clock unit 605 is reset consciously by the user if the current time of the clock unit 605 is reset. When any remote control operation is performed without resetting the time, the current time of the clock unit 605 is reset. Therefore, a battery for operating the clock unit 605 is provided, a radio clock, etc. The time of the clock unit 605 can be adjusted without being provided, and the cost can be reduced. In addition, when the setting signal is transmitted, the start time information is transmitted and the current time information is not transmitted, and when the operation instruction excluding the setting signal is transmitted, the current time information is transmitted. Since it becomes easy to align the data length of the signal used for transmission among the operation instructions, it becomes easy to unify the communication data length of the processing target in each operation instruction. As a result, the lighting device 2 and the remote control device 3 It becomes easy to simplify the communication processing performed between the two.

  In addition, the illumination control unit 606 receives, for example, an instruction (second setting instruction) for increasing the illuminance of the discharge lamp 7 or lighting it completely from the receiving unit 601 between the setting time T0 and the start time T3. The lighting controller 606 lights the nightlight that is darker than the full lighting state, for example, turns on the auxiliary lighting 8 or dims the discharge lamp 7 with a brightness below a certain illuminance at the time of the first reception. Or when the discharge lamp 7 is controlled to be dimmed and lighted with the minimum brightness, and the same instruction as the first time is received again by the receiving unit 601, the lighting control unit 606 accepts it. For example, the discharge lamp 7 may be fully turned on according to the instruction content.

  Thereby, for example, the user is highly likely to be sleeping between the set time T0 and the start time T3, and the user operates the button 301 of the operation unit 301 incorrectly because the lighting is dark, or the user is sleeping. Even if there is a single operation, the illuminance does not exceed a certain illuminance, it is not dazzling, it is bright enough not to wake up the user, and the operation based on the operation instruction can be performed by the second operation. It is possible to suppress erroneous operations and improve convenience. Note that the illumination control unit 606 receives the first operation to execute the instruction to turn on the nightlight, and turns on the nightlight when receiving an instruction requesting that the illuminance of the discharge lamp 7 be higher than a certain illuminance. It is good also as a structure which operate | moves.

  In addition, the remote control unit 304 in the remote control device 3 displays the setting button when a setting button for inputting a setting instruction is pressed and an input operation is accepted by the operation unit 301 between the setting time T0 and the start time T3. The setting instruction information is not transmitted when the time during which the button is pressed does not reach the predetermined setting time set in advance. On the other hand, when the setting button is continuously pressed for the set time or longer, the operation unit The setting instruction information received by 301 may be transmitted from the remote control transmission unit 305 to the reception unit 601.

  Then, when the time during which the setting button for inputting the setting instruction is pressed continues for a preset setting time or longer, setting instruction information indicating the setting instruction is transmitted from the remote control device 3 to the lighting device 2, In the lighting device 2, the setting instruction information received by the receiving unit 601 by the lighting control unit 606 is newly stored in the setting storage unit 604, or is already stored based on the received setting instruction information. May be changed.

  As a result, even if the user accidentally presses the setting button, the setting instruction information is not transmitted unless the setting button is pressed for more than the set time, so that the user's erroneous operation can be reduced, and the user can feel at ease. Can be increased. In addition, the user uses the operation unit 301 to store new setting instruction information in the setting storage unit 604 between the setting time T0 and the start time T3 in which the setting instruction information is already set, or has already been stored. Since the setting instruction information can be changed, the convenience can be improved.

  The remote control device 3 further includes a remote control clock unit (not shown) that measures the current time. When a setting instruction is received by the operation unit 301, the setting signal is transmitted to the lighting device 2 as described above. When it is detected that the start time T3 indicated by the start time information stored in the storage unit 303 is reached based on the current time obtained by the remote control clock unit (not shown), the storage unit 303 stores the start time again. The set instruction information that has been set may be transmitted to the lighting device 2 to execute an illumination control program, such as a wake-up program, indicated by the set instruction information at the start time T3.

  As described above, the remote control device 3 transmits the setting instruction information to the lighting device 2 when receiving the operation input of the setting instruction, and transmits the setting instruction information to the lighting device 2 at the execution start time of the lighting control program. Thus, for example, the setting instruction information stored in the setting storage unit 604 is erased between the setting time T0 and the start time T3 due to, for example, an instantaneous power failure due to a lightning strike or the malfunction of the lighting device 2. However, the lighting processing unit 612 can start execution of the wake-up program at the start time T3, and the certainty of the lighting start operation by the lighting device 2 can be improved.

(Second Embodiment)
Next, an illumination system according to the second embodiment of the present invention will be described. FIG. 12 is a block diagram showing an example of the configuration of the illumination system 1a according to the second embodiment of the present invention. The illumination system 1a shown in FIG. 12 differs from the illumination system 1 shown in FIG. 2 in the following points. That is, in the illumination system 1a shown in FIG. 12, the illumination device 2a includes a microcontroller in which the illumination control unit 606a does not include the clock unit 605, and has a built-in timer circuit that operates based on the clock signal supplied from the oscillator 613, for example. The illumination control unit 606a includes a timer unit 614 configured using, for example, a timer circuit built in the microcontroller. In addition, the remote control device 3a includes a clock unit 309 configured in the same manner as the clock unit 605.

  Since the other configuration is the same as that of the illumination system 1 shown in FIG. 2, the description thereof is omitted, and the operation of the present embodiment will be described below. Referring to the flowchart shown in FIG. 3, remote control device 3a shown in FIG. 12 has start time information stored in storage unit 303 and current time obtained in clock unit 309 by remote control control unit 304 in step S3. Is received as a timer value, and a setting signal containing the calculated timer value, information indicating the wake-up program, and current time information indicating the current time as setting instruction information is received from the remote control transmission unit 305. Transmitted to the unit 601.

  In step S5, setting instruction information stored in the setting signal received by the receiving unit 601 by the lighting control unit 606 in the lighting device 2, that is, a timer value, information indicating the wake-up program, and current time information are obtained. Of the setting instruction information stored in the setting storage unit 604 and received in the setting signal received by the receiving unit 601, a timer value is set in the timer unit 614, and the timer unit 614 counts down the timer value. Is started.

  The remote control unit 304 transmits a setting signal containing start time information, information indicating the wake-up program, and current time information indicating the current time as setting instruction information from the remote control transmission unit 305 to the reception unit 601. The illumination controller 606 may set the difference between the start time information and the current time information stored in the setting signal received by the receiver 601 as the timer value (set time) in the timer unit 614.

  In step S7, the notification processing unit 610 calculates the start time T3 by adding the current time information stored in the setting storage unit 604 and the timer value. Based on the calculated start time T3, for example, The content of the setting instruction information is notified by voice such as “The wake-up program has been set at 6:30”. In step S11, when the timer unit 614 times up, the process proceeds to step S12.

  Other operations are the same as those in the flowchart shown in FIG. As a result, the lighting system 1a shown in FIG. 12 has the setting instruction information stored in the setting storage unit 604 and the timer unit at the start time T3, similarly to the lighting system 1 shown in FIG. Since the execution of the wake-up program can be started based on the time measured by 614, for example, when the user falls the remote control device 3a while sleeping, changes the position or orientation, covers the futon, etc. Even if communication from the remote control device 3a to the lighting device 2a is not possible, lighting control based on the wake-up program is started at the start time T3 indicated by the start time information stored as the setting instruction information in the setting storage unit 604 can do.

  As in the lighting system 1 shown in FIG. 2 described above, in the configuration in which the lighting control operation in steps S11 and S12 is performed based on the setting on / off information associated with the setting instruction information, the remote control control unit 304 includes: When transmitting the setting instruction information to the lighting device 2a, the start time information is transmitted from the remote control transmission unit 305 to the reception unit 601, and the start time information is stored in the setting storage unit 604 in step S5. When transmitting the setting on / off information from the remote control transmission unit 305 to the reception unit 601, the current time information obtained by the clock unit 309 is transmitted together with the setting on / off information. The illumination control unit 606 a is configured to receive the setting on / off information by the reception unit 601. Current time information received together with the setting on / off information and the setting storage unit 6 The difference between the start time information 4 stored set in the timer unit 614 as the timer value may be configured to start the down counting of the timer value by the timer unit 614.

  In this case, each time the setting on / off information is transmitted from the remote control unit 304, the latest current time information is transmitted, and the timer unit 614 restarts the countdown of the timer value based on the current time information. Along with the transmission of information, the timer value of the timer unit 614 is corrected based on the latest current time information, and a low-accuracy timer circuit can be used as the timer unit 614, thereby reducing costs.

(Third embodiment)
Next, an illumination system according to the third embodiment of the present invention will be described. FIG. 13 is a block diagram illustrating an example of a configuration of an illumination system 1b according to the third embodiment of the present invention. The illumination system 1b shown in FIG. 13 differs from the illumination system 1a shown in FIG. 12 in the following points. That is, in the illumination system 1b shown in FIG. 13, the illumination device 2b is configured such that the illumination control unit 606b uses a microcontroller with a built-in counter circuit, for example, and the illumination control unit 606b is replaced with the timer unit 614. For example, a counter unit 615 configured using a counter circuit built in the microcontroller is provided. The counter unit 615 is a down counter that subtracts and counts a set count value, for example. The counter unit 615 is connected to a power cycle detection unit 616 that detects so-called zero cross timing of the commercial AC power source AC. Furthermore, a power-off storage unit 617 configured by, for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory) that is a nonvolatile memory is connected to the illumination control unit 606b.

  FIG. 14 is a block diagram for explaining an example of the configuration of the power cycle detection unit 616. 14 includes a rectifier 618 that outputs a rectified voltage Va obtained by full-wave rectifying the commercial AC power supply voltage AC, and a detection signal Vb when the rectified voltage Va is equal to or lower than a predetermined reference voltage Vref. Is output to the counter unit 615 at a high level. As a result, as shown in FIG. 15, a pulse signal synchronized with the pulsating valley of the rectified voltage Va is obtained as the detection signal Vb. In other words, the detection signal Vb is a periodic pulse signal having a half period of the period in the commercial AC power supply voltage AC.

  In this case, if the commercial AC power supply voltage AC is 50 Hz, the pulse period of the detection signal Vb is 10.0 msec (milliseconds), and if it is 60 Hz, the pulse period of the detection signal Vb is 8.33 msec (milliseconds). .

  The counter unit 615 functions as a timer by counting the pulse signal of the detection signal Vb, and the counter value of the counter unit 615 corresponds to the timer value of the timer unit 614 shown in FIG. In this case, since the time corresponding to one count differs depending on whether the commercial AC power supply voltage AC is 50 Hz or 60 Hz, when the supply of the commercial AC power supply voltage AC is started, the illumination control unit 606b The frequency of the commercial AC power supply voltage AC may be determined using the detection signal Vb, and the count value of the counter unit 615 may be corrected. Further, since it is possible to detect a power failure due to a power failure or the like by detecting that the pulse of the detection signal Vb has disappeared, the power cycle detection unit 616 also serves as a power failure detection unit for detecting a power failure. Function. In this case, when a power failure detection or power recovery detection function is added to the lighting device 2b, the power cycle detection unit 616 can be used in combination as a power failure detection unit.

  Accordingly, the lighting device 2b illustrated in FIG. 13 operates in the same manner as the lighting device 2a illustrated in FIG. 12, and therefore, at the start time T3, the lighting processing unit 612 includes the setting instruction information stored in the setting storage unit 604. Based on the time measured by the counter unit 615, the execution of the wake-up program can be started. For example, the user may defeat the remote control device 3b while sleeping, change the position or orientation, or cover the futon. Even when communication from the remote control device 3b to the lighting device 2b is not possible, the lighting control based on the wake-up program at the start time T3 indicated by the start time information stored as the setting instruction information in the setting storage unit 604 Can start.

  In addition, the lighting system 1b illustrated in FIG. 13 performs a power-off recovery operation that recovers the setting instruction information when the power is shut down such as a power failure. FIG. 16 is a flowchart for explaining the power-off recovery operation by the lighting system 1b. First, when it is detected by the illumination control unit 606b that the pulse of the detection signal Vb output from the power supply cycle detection unit 616 has disappeared, a power-off is detected (YES in step S41), the illumination control unit By 606b, information indicating that the power cut has occurred is stored in the power cut storage unit 617 (step S42).

  When the power supply voltage for the operation of the control block 6b is not supplied from the power supply circuit unit 21 due to the power interruption, the setting instruction information stored in the setting storage unit 604 and the counter value set in the counter unit 615 are changed. It will not be retained and will be initialized. Then, the illumination control unit 606b cannot execute the wake-up program even when the start time T3 is reached.

  Therefore, when the power failure such as a power failure is resolved and power is restored, and the power supply voltage for operation is supplied from the power supply circuit unit 21 to the control block 6b, the power-off storage unit 617 is first read by the illumination control unit 606b. If the information indicating that the power interruption has occurred is not stored (NO in step S44), the process proceeds to step S41 to detect the power interruption again in the normal processing, and the information indicating that the power interruption has occurred is stored. If so (YES in step S44), a retransmission request signal for instructing retransmission of the setting instruction information is transmitted from transmitter 602 to remote control receiver 306 (step S45).

  On the other hand, in the remote control device 3b, the remote control reception unit 306 receives the retransmission request signal from the transmission unit 602 (step S46), and the remote control control unit 304b stores the setting instruction information stored in the storage unit 303. The (first setting signal) is transmitted from the remote control transmission unit 305 to the reception unit 601 (step S47). When the receiving unit 601 in the lighting device 2b receives the setting signal from the remote control transmitting unit 305 (YES in step S48), the setting instruction information accommodated in the received setting signal is stored in the setting storage unit 604. The count value stored and further included in the setting instruction information is set in the counter unit 615 (step S49).

  As a result, even if the power is cut off due to a power failure or the like, the operation can be continued based on the setting instruction information stored in the nonvolatile storage unit 303 in the remote control device 3b after the power recovery. The lighting control based on the wake-up program can be started at the start time T3.

  On the other hand, in step S48, for example, setting instruction information from the remote control device 3b to the lighting device 2b when the user falls the remote control device 3b while sleeping, changes the position or orientation, covers the futon, etc. When the signal is not received by the reception unit 601 (NO in step S48), the notification processing unit 610 outputs a signal for notifying an error to the speech synthesis circuit 607, and the speaker 608 according to the signal output from the speech synthesis circuit 607. Thus, for example, “the set illumination control program cannot be executed” is notified by voice that the illumination control program cannot be executed (step S50). In this case, it is good also as a structure alert | reported that an illumination control program cannot be performed by methods other than an audio | voice like step S7.

  Thereby, when the set illumination control program cannot be executed due to a power failure such as a power failure, it is possible to notify the user to that effect, so that convenience and security for the user can be improved.

(Fourth embodiment)
Next, an illumination system according to a fourth embodiment of the present invention will be described. FIG. 17 is a block diagram illustrating an example of a configuration of an illumination system 1c according to the fourth embodiment of the present invention. The illumination system 1c shown in FIG. 17 differs from the illumination systems 1, 1a, 1b described above in the following points. That is, the illumination system 1c shown in FIG. 17 does not include the transmission unit 602, and the lighting circuit 5a modulates the light emitted from the discharge lamp 7 based on the transmission signal SD from the illumination control unit 606. The transmission signal SD is superimposed on the light emitted from 7 and transmitted to the remote control device 3c.

  In the remote control device 3c, the remote control reception unit 306a, which is an example of the superimposition information acquisition unit, receives the light emitted from the discharge lamp 7, and detects the transmission signal SD superimposed on the light, thereby obtaining the transmission signal SD. Receive. In this case, the transmission signal SD is, for example, a setting signal transmitted from the lighting device 2 to the remote control device 3 in step S6 shown in FIG. 3 and step S24 shown in FIG. 10, and the remote control device from the lighting device 2b in step S45 shown in FIG. It is a retransmission request signal transmitted to the device 3b.

  FIG. 18 is a block diagram illustrating an example of the lighting circuit 5a. The lighting circuit 5a illustrated in FIG. 18 includes, for example, a filter circuit 501 that removes noise from the commercial AC power supply voltage AC, a rectifier circuit 502 that rectifies the AC voltage from which noise has been removed by the filter circuit 501, and a voltage rectified by the rectifier circuit 502. A chopper circuit 503 that converts the voltage into a DC voltage, a chopper control circuit 504 that controls the operation of the chopper circuit 503, a capacitor 505 that smoothes the output voltage of the chopper circuit 503, and transistors Q1 and Q2 connected across the capacitor 505 in series. The circuit includes a series circuit of a capacitor C1, an inductor L1, and a capacitor C2 connected between the output terminals of the transistor Q2, and a discharge lamp 7 is connected in parallel with the capacitor C2.

  A dimming / modulating unit 506 is connected to the gates of the transistors Q1 and Q2. The dimming modulation unit 506 modulates the light emitted from the discharge lamp 7 in accordance with the dimming signal SC output from the illumination control unit 606 and superimposes the dimming signal SC on the light. The illumination control unit 606 The dimming signal I / F 507 for receiving the dimming signal SC output from the light source, the oscillation circuit 508, the oscillation control circuit 509 for controlling the oscillation operation of the oscillation circuit 508, and the transmission signal SD output from the illumination control unit 606. Based on the periodic signal output from the oscillation circuit 508, based on the control signal output from the duty ratio setting circuit 510 for setting the duty ratio for turning on and off the transistors Q1 and Q2, and the control signal output from the duty ratio setting circuit 510 And a driver circuit 511 for alternately turning on and off the transistors Q1 and Q2.

  Next, the operation of the lighting circuit 5a configured as described above will be described. FIG. 19 is a signal waveform diagram for explaining the operation of the lighting circuit 5a. First, when the transmission signal SD output from the illumination control unit 606 is at a low level or when there is no signal input, the output is performed from the oscillation circuit 508 by the duty ratio setting circuit 510 as shown in FIG. A control signal with a duty of 50%, in which approximately half the period of the periodic signal is turned on, is output to the driver circuit 511, and the driver circuit 511 turns the transistors Q1 and Q2 on and off alternately so that they are turned on for the same time. . As a result, the waveform of the lamp current Ila flowing through the discharge lamp 7 becomes sinusoidal as shown in FIG. 19A and no harmonic distortion is generated. Therefore, the harmonic distortion is also generated in the light emitted from the discharge lamp 7. Not superimposed.

  On the other hand, when the transmission signal SD output from the illumination control unit 606 is at a high level, as shown in FIG. 19B, the duty ratio setting circuit 510 outputs from the oscillation circuit 508 to increase the ON ratio of the transistor Q2. The control signal in which the duty of the periodic signal is changed is output to the driver circuit 511, and the driver circuit 511 alternately turns on and off so that the on ratio of the transistor Q2 is larger than the on ratio of the transistor Q1. Then, harmonic distortion occurs in the waveform of the lamp current Ila flowing through the discharge lamp 7 as shown in FIG. 19B, and accordingly, harmonic distortion components are also superimposed on the light emitted from the discharge lamp 7.

  Thereby, the light emitted from the discharge lamp 7 is modulated, and the transmission signal SD is superimposed on the light emitted from the discharge lamp 7 and transmitted to the remote control device 3c. In the remote control device 3c, the remote control receiving unit 306a receives the frequency component of the high frequency distortion in the light emitted from the discharge lamp 7 as a signal, and the presence / absence of the frequency component of the high frequency distortion is converted into the high and low levels of the signal. Thus, the transmission signal SD is received.

  On the other hand, the dimming control of the discharge lamp 7 is performed by changing the frequency of the periodic signal output from the oscillation circuit 508 according to the dimming signal SC output from the illumination control unit 606 to turn on / off the transistors Q1 and Q2. Can be performed independently of superimposition of the transmission signal SD. The frequency dimming is performed by changing the frequency within the range of the total lighting frequency, for example, 50 kHz to about 100 kHz. However, the harmonic distortion component of the lamp current Ila has a higher frequency band, for example, 2 of the fundamental frequency. Since the frequency is about 100 to 500 kHz, which is more than doubled, the frequency for lighting the lamp and the harmonic component of the signal on which the transmission signal SD is superimposed can be distinguished by the frequency, and the on / off frequencies of the transistors Q1 and Q2 can be determined. Also in the continuous light control type discharge lamp lighting device that performs light control by changing the light intensity, the transmission signal SD can be superimposed on the light emitted from the discharge lamp 7.

  Thereby, since the transmission signal SD can be superimposed on the light emitted from the discharge lamp 7, the transmission unit 602 transmits the transmission signal from the illumination device 2 to the remote control device 3 using a directional optical signal such as an infrared LED. Since the transmission signal SD can be transmitted and received irrespective of the positional relationship between the lighting device 2c and the remote control device 3c, compared to the case of transmitting SD, transmission in the transmission signal SD from the lighting device 2c to the remote control device 3c is possible. The certainty of operation can be improved.
