The technology for connecting these home appliances 80 via the network 70 may be a known technology as disclosed in, for example, Japanese Patent Laid-Open No. 2015-46950, and is not a new matter. Therefore, further explanation is omitted here.

  The wireless communication device 200 is a so-called general-purpose communication device except a lighting control device such as the lighting controller 201. The wireless communication device 200 includes various communication devices. For example, a portable mobile terminal can be a smartphone, a mobile phone other than a smartphone, a tablet personal computer, a PDA (Personal Digital Assistant), or a laptop personal computer. It may be. Further, the present invention is not necessarily limited to a portable portable terminal, and may be a stationary communication terminal in which a wireless LAN is constructed, specifically, a desktop personal computer. The lighting controller 201 controls lighting of the lighting fixture 100 by power on / off and a dimming command value from a remote controller (not shown).

Operation of the apparatus according to the embodiment.
The control device 40 can execute “wake-up light control” and “sleeping-off control” described below. In order to execute these controls, the storage unit 43 stores in advance electronic data including a “wake-up lighting control program”, a “sleeping-off control program”, an “alarm lighting setting program”, and a “sleeping-off setting program”. Is remembered.

  The dimming control in the wake-up lighting control and the bedtime extinction control has a preset time set by the user, and the preset “start dimming rate” from the preset control start time to the preset time is “end”. It is similar in that the brightness of the light source module 27 is gradually changed until the dimming rate. However, in the alarm lighting control, the set time is "time to get up", the start dimming rate is set to the lower limit dimming rate, and the end dimming rate is set to the upper limit dimming rate to gradually increase the brightness. Control is performed. On the other hand, in the turn-off control at bedtime, the set time is "scheduled time to go to bed", the start dimming rate is the upper limit dimming rate, and the end dimming rate is the lower limit dimming rate, and the brightness gradually Dimming control is performed to lower

(Alarm light control according to the embodiment)
FIG. 2 is a time chart illustrating a processing flow in the alarm lighting control according to the embodiment. In FIG. 2, as an example, from the alarm lighting control start time t1 to the scheduled wake up time t2, a predetermined dimming rate predetermined in the range of 5% to 25% is set as a lower limit, and an upper limit ), The light control is performed to continuously increase the brightness according to the passage of time. In addition, after it becomes all the light at the scheduled wake-up time t2, the control device 40 automatically turns off the light source module 27 at time t3 when a predetermined turn-off condition (steps S112 to S116 in FIG. 4) described later is satisfied. FIG. 2 illustrates the dimming control in which the lower limit dimming level is immediately brought to the upper limit dimming level over a predetermined time immediately before being brought to the lower limit dimming level. It may be configured to hold only for a predetermined time.

(Alarm setting screen)
FIG. 3 is a diagram illustrating an example of a setting screen in the alarm light control according to the embodiment. In the present embodiment, the contents of the alarm light control can be adjusted according to the user's preference. Specifically, setting values of time and brightness can be set arbitrarily. As a result, it is possible to realize lighting control that allows each user to get up comfortably. The user uses the wireless communication device 200 such as a smartphone to launch the alarm setting screen shown in FIG. A scheduled wake-up time and the like can be set on the screen of the wireless communication device 200 via the user interface shown in FIG.

  For a plurality of setting values to be input on the setting screen, information for determining the wakeup scheduled time t2 and the alarm lighting control start time t1 (that is, how many minutes before the alarm scheduled time to start the alarm lighting control Time value, upper limit dimming rate and lower limit dimming rate, dimming pattern, automatic turn-off time, and presence or absence of home appliance cooperation. In FIG. 3, the time from the wake-up lighting control start time t1 to the scheduled wake-up time t2 is set to 5 minutes, but this is an example, and there are individual differences, so that the time can be increased or decreased. It has become. In the example shown in FIG. 3, both the upper limit dimming rate and the lower limit dimming rate are variably set in the wake-up lighting control, but the upper limit dimming rate is fixed at all lighting (that is, dimming rate = 100%). Only the lower limit dimming rate may be variably set, or vice versa. Further, a plurality of light control patterns may be stored so that the user can select. For example, three dimming patterns A, B, and C may be stored and selected by the user. As shown in FIG. 2, the light control pattern A is assumed to increase the brightness by continuous light control as a linear function from the lower limit light control rate toward the upper limit light control rate. The light control pattern B may be configured to increase brightness in a step-like manner (in a step-like light control) from the lower limit light control rate to the upper limit light control rate. The dimming pattern C increases brightness from the lower limit dimming rate at the first rate of change, and a second rate of change different from the first rate of change (may be larger or smaller than the first rate of change). The brightness may be increased to reach the upper limit dimming rate. The “automatic turn-off time” and “presence or absence of home appliance cooperation” are setting values used in the processing of steps S112 and S116 in the flowchart of FIG. 4 described later.

  The wireless communication device 200 transmits the alarm setting wireless signal including the various setting values to the control device 40. The wireless communication device 200 transmits the input setting value to the control device 40. The control device 40 receives the wireless signal from the wireless communication device 200 by the antenna 50 and the transmitting and receiving unit 46, and stores the setting value in the storage unit 43. When the current time measured by the timer 47 matches the alarm lighting control start time, the control device 40 executes the light adjustment control program in accordance with the latest set value.

  In the present embodiment, as an example, the wireless communication device 200 is used as the “input communication device” for inputting each setting value in FIG. 3, and the light-off signal in step S114 described later for the wireless communication device 200. It is also used for transmission. However, the input device for the alarm setting screen and the communication device for transmitting the turn-off signal in step S114 in FIG. 4 may be different devices. Further, the setting value input to the control device 40 via the setting screen is not limited to the case where it is performed by a wireless signal, and a wake-up setting signal and a turn-off signal are wired to the control device 40 from a wired setting device (wired controller) (not shown). You may make it transmit.

(Specific processing of alarm light control)
FIG. 4 is a flowchart for explaining a processing flow in the alarm lighting control according to the embodiment. When the arithmetic processing unit 45 of the control device 40 receives the alarm setting wireless signal via the antenna 50 and the transmission / reception unit 46, the arithmetic processing unit 45 executes the alarm lighting control program stored in advance in the storage unit 43.

  In the processing flow of FIG. 4, first, the arithmetic processing unit 45 reads a set value stored in advance in the storage unit 43 (step S100). The arithmetic processing unit 45 calculates the alarm lighting control start time t1 from the values of the scheduled wakeup time and the alarm lighting control start time included in the setting value (step S102). As an example, in FIG. 3, since the alarm lighting control start time t1 is set 5 minutes before the wakeup scheduled time t2 (6:00 in the example of FIG. 3) by the user, 5 minutes from the wakeup scheduled time t2 The time obtained by subtracting H is set to the alarm lighting control start time t1 (5:55 in the example of FIG. 3).

  Next, the arithmetic processing unit 45 detects the current time with the timer 47 in accordance with the wake-up lighting control program, and determines whether or not the current time has reached the wake-up lighting control start time t1 (step S104). Until the current time reaches the alarm lighting control start time t1, the standby state is established.

  When the current time reaches the alarm lighting control start time t1, the arithmetic processing unit 45 starts lighting at the lower limit dimming rate (step S106). Specifically, the arithmetic processing unit 45 sends a control signal to the control circuit 42 so as to light the LED 27 a at the lower limit dimming rate predetermined by the user. The control circuit 42 controls the ON time of the switching element Q2 based on the control signal, and turns on the light source module 27 with the lower limit dimming. In FIG. 3, the lower limit dimming rate is set to 5% by the user as an example. The lower limit dimming rate may be selected by the user in the range of 5 to 25% dimming rate, for example.

  After that, the arithmetic processing unit 45 increases the dimming rate as soon as the lower limit dimming rate is reached according to the alarm lighting control program (step S108). Specifically, the arithmetic processing unit 45 is configured to have a predetermined upper limit dimming rate (for example, total light, ie, 100% dimming rate) at a scheduled wake-up time after 5 minutes from the lower limit dimming time. In addition, a control signal is sent to the control circuit 42 so as to increase the dimming rate at a constant speed from the lower limit dimming operation time of the 5 minutes to the full light illumination time. The control circuit 42 controls the on time of the switching element Q2 based on the control signal, and raises the dimming rate at a fixed time from the lower limit dimming lighting time to the wakeup scheduled time of 5 minutes. Such dimming control is performed, and finally the light source module 27 is turned on at all scheduled wake-up times t2 (step S110).

  After step S110, the process proceeds to steps S112 to S116. In the embodiment, after reaching the scheduled wake-up time t2, the controller 40 turns off the light source module 27 when various light-off conditions described below are satisfied without the light source module 27 being turned off. An alarm lighting control program has been established.

  Specifically, first, after the scheduled wake-up time t2 (all light), the arithmetic processing unit 45 uses a timer 47 timer function to elapse a predetermined automatic turn-off time (for example, 5 minutes). It is determined whether or not (step S112). If the light source module 27 is still on even after the automatic turn-off time has elapsed, the possibility of forgetting to turn off is high. Therefore, the processing unit 45 sends a control signal to the control circuit 42 so as to turn off the LED 27a automatically (step S124). The control circuit 42 stops the operation of the switching element Q2 based on the control signal. In the setting screen of FIG. 3, the value of the automatic turn-off time can be changed to a value other than 5 minutes according to the user's preference.

  In addition, the arithmetic processing unit 45 determines whether or not the turn-off signal instructing turn-off of the light source module 27 is received from the wireless communication device 200 other than the illumination control device via the antenna 50 of the control device 40 Step S114). When the controller 40 receives the turn-off signal by the antenna 50, it sends a control signal to the control circuit 42 to turn off the light source module 27 as in step S112 (step S124).

  By doing this, after the user wakes up, by manually operating the wireless communication device 200, the controller 40 can be notified of the light-off signal and turned off. That is, in step S114, the turning off of the LED 27a is performed based on the manual operation, not the automatic turning off based on the passage of time. Even in such a method, when the user forgets to turn off the lighting switch SW, when operating another wireless communication device such as a smartphone, the user notifies the turn-off signal and turns off the light source module 27. It has the effect of suppressing forgetting to turn off because it can create an opportunity to The turn-off time may be set in advance in the wireless communication device 200, and the wireless communication device 200 may automatically notify the control device 40 of the turn-off signal when the turn-off time is reached.

  Further, the arithmetic processing unit 45 determines whether or not the turn-off signal emitted from the home appliance 80 has been received (step S116). As described above, the signal from the home appliance 80 is to be transmitted to the antenna 50 of the control device 40 via the network 70. In the present embodiment, a system including the home appliance 80, the network 70, and the lighting device 1 is configured such that when the home appliance 80 such as the air conditioner 81 is turned on, the home appliance 80 automatically issues a turn-off signal to the control device 40. Has been. The turn-off signal is emitted from the home appliance 80 when the home appliance 80 is powered on. The control device 40 sends a control signal to the control circuit 42 so as to turn off the light source module 27 when receiving the light-off signal from the home appliance 80 (step S124). In addition, if "a household appliance cooperation" is set to "none" on the setting screen of FIG. 3, the process of step S116 will be abbreviate | omitted.

  According to the alarm lighting control as described above, by providing the extinguishing function other than the illumination switch SW, it is possible to suppress the extinguishing failure even if there is no operation of extinguishing with the illumination switch SW, and the usability is improved. Moreover, since it can be awakened by giving a visual stimulus by illumination without generating a sound like an alarm, it is possible to avoid an adverse effect due to the sound around the adjacent room or the like. In addition, since the light adjustment rate is gradually raised from a predetermined time before the scheduled wake-up time, the awakening can be promoted with a gentle visual sense than when the full wake-up is suddenly performed at the scheduled wake-up time.

(The bedtime turn-off control according to the embodiment)
FIG. 5 is a time chart for explaining a processing flow in bedtime extinction control according to the embodiment. From the bedtime extinguishing control start time t11 to the bedtime scheduled time t12, the control is continuously performed to lower the brightness from the upper limit dimming rate (for example, total light) to the lower limit dimming rate (for example, 5%). In addition, after becoming a lower limit light control by the going-to-sleep time t12, the lower limit light control lighting is maintained, and the control apparatus 40 is a light source at the time t13 when predetermined light extinction conditions (step S112-S216 of FIG. 7) mentioned later were satisfied. The module 27 is automatically turned off from the lower limit dimming control.

(Sleep setting screen)
FIG. 6 is a diagram illustrating an example of a setting screen in bedtime extinction control according to the embodiment. Input items similar to the alarm setting screen shown in FIG. 3 are listed. As a result, for example, it is possible to make adjustments such as changing the time from the turn-off lighting control start time to the scheduled sleep time to five minutes according to the user's preference. The contents of the bedtime setting screen shown in FIG. 6 can also be modified in the same manner as described with reference to FIG. For example, in the example of FIG. 6, both the upper limit dimming rate and the lower limit dimming rate are variably set. However, the upper limit dimming rate is fixed at all lighting (that is, the dimming rate = 100%), and the lower limit dimming rate is fixed. Only the rate may be set variably or vice versa. As a result, as in the case of the alarm light control, the contents of the light-off control at bedtime can be adjusted according to the preference of the user, and light-off control can be realized such that each user can go to bed comfortably.

  In addition, for example, in a lighting fixture which allows the user to arbitrarily set the light control rate, it is also conceivable that the light control rate is set to a light control rate less than the total light at the turn-off control start time t11. As a modified example corresponding to such a case, the current dimming rate at the bedtime extinguishing control start time t11 (for example, 80% dimming) without keeping the upper limit dimming rate at the bedtime extinguishing control start time t11 constant. ) May be set to the upper limit dimming rate, and the bedtime extinction control may be started as it is.

  The wireless communication device 200 transmits a bedtime extinction setting wireless signal including a plurality of setting values input on the setting screen of FIG. The wireless communication device 200 transmits the input setting value to the control device 40. The control device 40 receives the wireless signal from the wireless communication device 200 by the antenna 50 and the transmitting and receiving unit 46, and stores the setting value in the storage unit 43. When the current time measured by the timer 47 matches the bedtime turn-off control start time, the control device 40 executes the light adjustment control program in accordance with the latest set value.

  In addition, regarding the bedtime setting screen, the same modification as in the case of the alarm light control is possible. For example, the communication method for transmitting the setting value input on the sleeping setting screen to the control device 40 is not limited to wireless, but may be wired. Further, the input device for the sleep setting screen and the communication device for transmitting the turn-off signal in step S114 in FIG. 7 may be different devices.

(Concrete processing of bedtime extinguishing control)
FIG. 7 is a flowchart for explaining a processing flow in the bedtime extinction control according to the embodiment. When the arithmetic processing unit 45 of the control device 40 receives the bedtime extinction setting radio signal from the wireless communication device 200 via the antenna 50 and the transmission / reception unit 46, the arithmetic processing unit 45 executes the bedtime extinction control program stored in advance in the storage unit 43. To do. Hereinafter, in the processing flow of FIG. 7, the description of the portions similar to the processing flow described in FIG. 4 will be simplified or omitted in order to avoid redundant description.

  According to the process flow of FIG. 7, the arithmetic processing unit 45 first reads out the set value stored in advance in the storage unit 43 (step S200), and the scheduled bedtime in FIG. 6 (23:00) included in the set value. The bedtime turn-off control start time t11 (22:55 in the example of FIG. 6) is calculated from the value (5 minutes) of the bedtime turn-off control start time (step S202), and the current time is the bedtime turn-off control It is determined whether it coincides with the start time t11 (step S204).

  When the current time measured by the timer 47 reaches the bedtime extinguishing control start time t11, the arithmetic processing unit 45 starts to reduce the dimming rate from the upper limit dimming lighting (step S206). Specifically, the arithmetic processing unit 45 is configured to turn on at the lower limit dimming rate determined by the user at the scheduled bedtime t12 after 5 minutes from the time of all light, and further from the time of all light lighting. A control signal is sent to the control circuit 42 so as to decrease the dimming rate until the light is turned on at a constant speed over the five minutes. The control circuit 42 controls the on time of the switching element Q2 based on the control signal, and performs light adjustment at a constant speed from the scheduled sleep time t12 five minutes after the upper limit light adjustment time (here, all light on time). The rate is reduced, and the light source module 27 is lighted at a predetermined lower limit dimming rate at scheduled bedtime t12.

  In the bedtime extinguishing control program according to the embodiment, as in the case of the above-described alarm lighting control program, a device for suppressing the extinguishing failure is performed. That is, after reaching the scheduled sleep time t12, the lower limit light control lighting is maintained, and the control device 40 operates the light source when at least one of the following three lighting off conditions is satisfied without turning off the light source module 27: A bedtime turn-off control program is constructed so that the module 27 is turned off from the lower limit dimming. Two of the three turn-off conditions are that the determination conditions of step S112 and step S114 are satisfied, as in the process flow of FIG. 4. Thus, after reaching the scheduled sleep time t12, the arithmetic processing unit 45 sends a control signal to the control circuit 42 so that the light source module 27 is automatically turned off after 5 minutes, as an example. Further, the light source module 27 is turned off by receiving the light-off signal from the wireless communication device 200.

  The remaining one of the three turn-off conditions is determined by cooperation with the home appliance 80, as in step S116 of FIG. Similar to step S116 in FIG. 4, the flowchart in FIG. 7 also includes step S216 related to the home appliance cooperation process. The home appliance 80 includes the network 70 and the lighting device 1 so that when the home appliance 80 such as the air conditioner 81 is turned off, the home appliance 80 automatically issues a turn-off signal to realize the bedtime turn-off control. Assume that the system is configured. It is assumed that the home appliance 80 such as the air conditioner 81 has a built-in timer function that is automatically turned off at a predetermined timer off time. When the air conditioner 81 or the like is turned off at a preset timer off time, the light source module 27 can be turned off in conjunction with the air conditioner 81 or the like.

  According to the above-described bedtime extinguishing control, by providing an extinguishing function other than the illumination switch SW, it is possible to suppress the extinguishment forgetting at bedtime even if there is no operation of extinguishing with the illumination switch SW, and usability improves. In addition, since the light control rate is gradually lowered while the light control rate is gradually lowered from a predetermined time before the scheduled sleep time, sleep can be promoted with a gentle visual stimulus than when the light is suddenly turned off at the time of sleep. Furthermore, since the lower limit light adjustment lighting is held for a predetermined time and then automatically turned off, it is possible to realize sleeping / lighting suitable for, in particular, an infant or the like rather than the case where the light is suddenly turned off.

  In the above-described embodiment, the user can adjust the details of the light adjustment control according to his / her preference by the setting screen (see FIG. 3 and FIG. 6) of alarm light control or bedtime extinguishing control. . However, such adjustment function may be eliminated so that, for example, only the scheduled wake-up time or the scheduled sleep time may be set, and other setting values such as the light control rate may be modified to be fixed values. In that case, a lighting device having the technical feature that the light source module 27 is automatically turned off when a predetermined turn-off condition is satisfied after the dimming control for the wake-up lighting control or the bedtime turn-off control, and the lighting device A lighting fixture is provided.

  In the embodiment described above, after the brightness of the light source module 27 reaches the end light control rate of the light control (it is the upper limit light control rate in alarm light control and the lower limit light control rate in bedtime extinguishing control) The light source module 27 is automatically turned off when a predetermined turning off condition is satisfied. However, you may deform | transform so that such a light extinction function may be lost. In that case, a lighting device and a luminaire provided with the same are provided with the technical feature that the user can adjust the details of the light adjustment control to his / her preference by the setting screen.

  Note that each control including the above-described alarm lighting control, bedtime extinction control, and setting screens thereof is not limited to the microcomputer, and may be mounted on an arithmetic device such as a DSP (Digital Signal Processor). The control logic necessary for each of these controls may be built in advance in an arithmetic device such as a DSP.

  Further, in the above embodiment, the various setting values of FIG. 3 and FIG. 6 set in the wireless communication device 200 are notified to one lighting fixture 100 by the wireless communication device 200, and alarm lighting control and bedtime are performed. The case where the light-off control is performed is illustrated. However, when the various settings are notified to the lighting controller 201 and the lighting controller 201 notifies the plurality of lighting fixtures 100 previously associated with the lighting controller 201 by address setting, the alarm lighting control and the time of going to bed You may comprise so that light extinction control may be performed. According to this, the same effect can be obtained for the plurality of lighting fixtures 100 as well.
