  2. Description of the Related Art Conventionally, lighting devices having a function for awakening a sleeping person are known. For example, in Patent Document 1, an awakening operation that leads a sleeper to an arousal state by continuously changing the illuminance of light in the order of low illuminance, medium illuminance, and high illuminance from a predetermined time before the set wake-up time. An illumination device for performing is disclosed.

Japanese Patent No. 3767319

  However, even at low illuminance at the start of the awakening operation that activates the awakening operation, the sleeper may feel dazzled, and there is a concern that comfortable awakening may be hindered.

  Further, during the awakening operation, the sleeper may fall asleep and perform an erroneous operation, and may send some signal. In such a case, the continuous change in illuminance is interrupted, for example, the illuminance of light suddenly changes to a high illuminance, and there is a risk of hindering comfortable awakening.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, in the first invention, a light source unit capable of changing illuminance and a control unit for turning on, turning off, and dimming the light source unit, and starting awakening operation that is a predetermined time before the set wake-up time. When the time comes, the control unit turns on the light source unit and causes the light source unit to perform an awakening operation to change the illuminance of the light source unit from low illuminance to high illuminance. A main light source capable of changing illuminance, and an auxiliary light source capable of outputting light in an illuminance range lower than the illuminance range of the main light source, and the control unit has an illuminance of the main light source at the awakening operation start time The auxiliary light source is turned on at an illuminance in a lower illuminance range, the main light source is turned on after the auxiliary light source is turned on, and the illuminance of the main light source is gradually increased over time .

In the second invention, the control unit turns on the auxiliary light source at the awakening operation start time, and gradually increases the illuminance of the auxiliary light source over time .

In a third aspect, the control unit turns off the auxiliary light source before turning on the main light source, simultaneously with turning on the main light source, or after turning on the main light source.

In a fourth aspect of the invention, the control unit discriminates the lighting state of the light source unit when the awakening operation start time is reached, and turns off the light source unit when the light source unit is lit.

  In a fifth aspect of the invention, a light source unit capable of changing illuminance and a control unit for turning on, turning off, and dimming the light source unit, and at a wake-up operation start time that is a predetermined time before the set wake-up time In this case, the control unit turns on the light source unit and causes the light source unit to perform an awakening operation for changing the illuminance of the light source unit from low illuminance to high illuminance. When the first signal is input during the awakening operation, the light source unit is shifted to the signal waiting operation, and when the second signal is not input within a preset time after shifting to the signal waiting operation, When the second signal is input within a preset time after the signal waiting operation of the light source unit is ended, the wake-up operation is restored, and the signal waiting operation is performed, the light source unit End the signal waiting operation, It is intended to perform the operation according to the signal.

  In a sixth aspect of the invention, the light source unit includes a main light source capable of changing illuminance and an auxiliary light source capable of outputting light in an illuminance range lower than the illuminance range of the main light source. Is an operation of turning on the auxiliary light source with an illuminance in an illuminance range lower than that of the main light source.

In a seventh aspect, when the control unit ends the signal waiting operation of the light source unit and returns to the awakening operation, the illuminance of the light source unit is the illuminance when the awakening operation is continued. To do.

  As effects of the present invention, the following effects can be obtained.

  In the first invention, by turning on the auxiliary light source capable of outputting light in an illuminance range lower than the illuminance range of the main light source at the start of the awakening operation, the sleeper does not feel dazzling at the start of the awakening operation, and then gradually The brighter light can encourage sleep comforters.

  In the second invention, by gradually increasing the illuminance from the start of the awakening operation to the end of the awakening operation, the sleeper can be gradually brought to awakening, and the sleeper can be urged for a comfortable awakening. I can do it.

In the third invention, the auxiliary light source is turned off before turning on the main light source, simultaneously with turning on the main light source, or after turning on the main light source.

In the fourth invention, since the light source unit is turned off when the light source unit is turned on at the awakening operation start time, the awakening operation does not start from medium illuminance.

In the fifth invention, when the first signal is input during the awakening operation, the light source unit shifts to the signal waiting operation, but the second signal is received within a preset time after shifting to the signal waiting operation. If not input, the signal waiting operation of the light source unit is terminated and the awakening operation is restored. For this reason, even if the operation is abandoned during the awakening operation and an erroneous operation is performed, and the signal waiting operation is started, the awakening operation can be restored. Accordingly, it is possible to prevent an operation that hinders a comfortable awakening such that the illuminance of the light source suddenly becomes high due to an erroneous operation during the awakening operation.
Further, when the second signal is input within a preset time after the transition to the signal waiting operation, the signal waiting operation of the light source unit is terminated and the operation according to the second signal is performed. For this reason, when it is desired to intentionally switch to another operation during the awakening operation, the awakening operation can be switched to the desired operation by inputting the second signal.

  In the sixth aspect of the invention, the signal waiting operation of the light source unit is an operation of turning on the auxiliary light source with an illuminance in an illuminance range lower than the illuminance range of the main light source. can do.

In 7th invention, when complete | finishing the signal waiting operation | movement of a light source part, and making it return to an awakening operation, the illumination intensity of a light source part is taken as the illumination intensity when the awakening operation is continued. Since the illuminance of the light source unit is determined regardless of whether the awakening operation has shifted to the signal waiting operation, the illuminance of the light source unit can be easily determined.

Next, a first embodiment of the present invention will be described.
As shown in FIG. 1, the lighting device 1 according to the present invention includes a lighting device body 10 and a remote controller 20.
The illuminating device body 10 supplies the light source unit 15 including the main light source 151 and the auxiliary light source 152, the main light source lighting device 13 for changing the amount of power supplied to the main light source 151, and the auxiliary light source 152. The auxiliary light source lighting device 14 for changing the amount of power and a load signal for adjusting the amount of power supplied to the light source unit 15 are output to the main light source lighting device 13 and the auxiliary light source lighting device 14, and the light source unit 15. Is provided with a control unit 11 for turning on / off and dimming, and a remote control receiving unit 12 for outputting a signal such as a dimming signal to the control unit 11.
The remote controller 20 transmits a remote control signal to the remote control receiver 12, and switches on and off each light source of the light source unit 15 or changes (dims) the illuminance of each light source of the light source unit. A switch or the like for setting is provided.

In the present embodiment, a fluorescent lamp is used as the main light source 151 and an LED is used as the auxiliary light source 152. However, the main light source 151 and the auxiliary light source 152 are not limited to this, and any light source may be used. For example, an incandescent lamp may be used as the auxiliary light source 152, or an LED may be used as the main light source 151. Good.
Note that the auxiliary light source 152 has an illuminance range of low illuminance that does not feel dazzling even when it is lit during sleep.

For example, if the main light source 151 is a fluorescent lamp, the main light source lighting device 13 is configured by an inverter circuit, and is connected to an AC power source (not shown), and the amount of power supplied to the main light source 151 can be varied by adjusting the transmission frequency. The main light source 151 is dimmed as follows.
Further, for example, if the auxiliary light source 152 is an LED, the auxiliary light source lighting device 14 performs dimming of the auxiliary light source 152 by changing the amount of power supplied to the auxiliary light source 152 by controlling the phase of the voltage of the AC power source.

  When the lighting device 1 is used as normal room lighting, the control unit 11 controls the main light source 151 and the auxiliary light source 152 in accordance with signals such as turn-off, lighting, and dimming transmitted from the remote controller 20. Are output to the main light source lighting device 13 and the auxiliary light source lighting device 14.

Further, when the lighting device 1 is caused to perform an awakening operation, the control unit 11 determines a predetermined time from the wake-up time set in advance by the operator based on the time measured by the timer 114 in the control unit 11. Control is performed so that the illuminance of the main light source 151 is gradually increased based on a pattern stored in the ROM 112 in advance.
The pattern (wake-up operation) in which the illuminance of the light source unit 15 gradually increases will be described in detail later.

  Various signals from the remote controller 20 received by the remote controller receiver 12 are input to the CPU 111 of the controller 11, and the CPU 111 controls the main light source lighting device 13 and the auxiliary light source lighting device 14 according to the input signals. . For example, when a signal for lighting the main light source 151 is transmitted from the remote controller 20, the CPU 111 outputs a signal to the main light source lighting device 13 to light the main light source 151. When signals such as turning on, turning off, and dimming of the main light source 151 and auxiliary light source 152 are transmitted from the remote controller 20, the CPU 111 turns on, turns off, dimming, etc. to the main light source lighting device 13 and auxiliary light source lighting device 14. The signal is output.

  When the lighting device 1 is caused to perform an awakening operation, information such as a wake-up time input by the operator operating the remote controller 20 is received as a signal from the remote controller 20 by the remote controller receiver 12, and the remote controller receiver 12 is transmitted to the control unit 11 and stored in the RAM 113 in the control unit 11. For example, when wake-up time information (for example, 7:00 am) is transmitted from the remote controller 20 by an operator's operation, the wake-up time information is stored in the RAM 113, and the CPU 111 responds to the wake-up time information with the light source unit 15 Turn on, turn off, and light control.

Next, the awakening operation (a pattern in which the illuminance of the light source unit 15 gradually increases) will be described with reference to the flowchart shown in FIG. 2 and the operation explanatory diagrams of FIGS.
In the awakening operation, the light source unit 15 is turned on from a predetermined time t1 before the wake-up time t4, and the illuminance is continuously increased in the order of low illuminance, medium illuminance, and high illuminance until the awakening operation end time t3. Is an action that leads to awakening. In the awakening operation, the illuminance at the lighting start time t2 of the main light source 151 is set to the minimum illuminance L22, and the illuminance when the illuminance of the main light source 151 is most increased is set to the maximum illuminance L23. Further, the illuminance at the lighting start time t1 of the auxiliary light source 152 during the awakening operation is set to the minimum illuminance L11, and the illuminance when the illuminance of the auxiliary light source 152 is most increased is set to L12.

  Before going to bed, the wake-up time t4 is set by the remote controller 20, and a signal for reserving an awakening operation is transmitted to the lighting device body 10 side (step S101). The remote control receiving unit 12 receives the signal, and the control unit 11 stores a predetermined time before the wake-up time t4 (30 minutes in the present embodiment) as the awakening operation start time t1. When the control unit 11 reaches the awakening operation start time t1 by the timer 114 (Yes in step S102), the control unit 11 starts the awakening operation. The interval between the awakening operation start time t1 and the wake-up time t4 can be set to a desired time.

  At the awakening operation start time t1, the control unit 11 determines whether or not the light source unit 15 is turned on. If the light source of the light source unit 15 is turned on (Yes in step S103), the light source unit 15 is turned on. Are turned off (step S104). For example, when the main light source 151 is turned on, the main light source 151 is turned off as shown in FIG. Therefore, for example, even if the main light source 151 is accidentally forgotten to be turned off at the time of going to bed, or when sleeping with the auxiliary light source 152 turned on, all the light sources are temporarily turned off when entering the awakening operation. .

  Therefore, even when the wake-up operation start time t1 is reached in a state where the main light source 151 is lit at medium illuminance, the wake-up operation does not start from medium illuminance. As shown in FIG. 3, when all the light sources 15 are turned off and the awakening operation start time t1 is reached, the awakening operation is started as it is from the state where all the light sources 15 are turned off.

  When the awakening operation is started (step S105), as shown in FIG. 3b, first, the auxiliary light source 152 is turned on (step S106), and the illuminance of the auxiliary light source 152 gradually increases as time passes. (Step S107). At this time, the illuminance of the auxiliary light source 152 is determined with respect to the elapsed time from the lighting start time t1. Thus, the awakening operation starts when the auxiliary light source 152 is turned on from the extinguished state. Note that the illuminance of the auxiliary light source 152 is a low illuminance that does not feel dazzling even when it is lit during sleep. At the lighting start time t1, the auxiliary light source 152 starts lighting at the illuminance L11 lower than the minimum illuminance L22 of the main light source 151. The maximum illuminance L12 when the illuminance is increased most immediately before the lighting of the auxiliary light source 152 is finished may be lower or higher than the minimum illuminance L22 of the main light source 151. In this embodiment, the illuminance of the auxiliary light source 152 gradually increases. However, the illuminance of the auxiliary light source 152 that is turned on from time t1 to time t2 is constant from turning on to turning off. Also good. Time t2 is a time at which the auxiliary light source 152 is switched from being turned on to turning on the main light source 151.

  Further, the lighting time of the auxiliary light source 152 may be anything that is lit until the sleeper gets used to the brightness so that the sleeper does not feel dazzling. The interval from t1 to t2 is awakening. The time is set shorter than the time from the start to the end of the operation. Although the length depends on the total time for performing the awakening operation, it is about 10 seconds to several minutes, for example, about 90 seconds, and the time until the sleeper gets used to the brightness is appropriately set. I will do it.

  Then, at time t2 when the illuminance of the auxiliary light source 152 reaches the maximum illuminance L12 (Yes in step S108), the control unit 11 turns off the auxiliary light source 152 (step S109), as shown in FIG. Subsequent to turning off, the main light source 151 is turned on as shown in FIG. 3a (step S110). The illuminance of the main light source 151 gradually increases with time (step S111). The main light source 151 is lit with the illuminance determined for the elapsed time from the lighting start time t2. In this embodiment, the main light source 151 is turned on after the auxiliary light source 152 is turned off. However, the main light source 151 is not necessarily turned on after the auxiliary light source 152 is turned off. The main light source 151 may be turned on while the light source 152 is turned on. Further, the auxiliary light source 152 may be turned off and the main light source 151 may be turned on simultaneously.

  Then, the main light source 151 gradually increases the illuminance from the minimum illuminance L22, and reaches a time t3 that is a predetermined time before the wake-up time t4 (in this embodiment, 1 minute before) (Yes in step S112). When 151 reaches the maximum illuminance L23, the illuminance of the main light source 151 is maintained at the maximum illuminance L23, and the awakening operation ends (step S113). That is, the light source unit 15 gradually increases the illuminance over 29 minutes from the wake-up operation start time t1 to 1 time before the wake-up time t4 and to the time t3 when the wake-up operation ends. From a deep sleep state to a shallow sleep state.

  Next, the second embodiment will be described. If the remote controller 20 can be turned on, turned off, and dimmed freely during the awakening operation as described above, the sleeper may fall asleep and misoperate, resulting in a sudden increase in illuminance and a comfortable sleep. May be inhibited. In the second embodiment, the illuminance is prevented from rapidly increasing due to an erroneous operation of the remote controller 20 during the awakening operation. Hereinafter, this operation will be described with reference to the flowchart shown in FIG. 5 and the operation explanatory diagrams of FIGS.

  As shown in FIG. 5, when it is detected that it is time t1 when the awakening operation is started (Yes in step S201), the awakening operation is started (step S202). At time t5 after the main light source 151 is turned on, some switches such as a switch for turning on / off the light source of the light source unit 15 and a switch for changing (dimming) the illuminance of the light source are operated by the operator. Then, a signal (information such as turning on / off the light source, changing illuminance (dimming), etc.) corresponding to the operated switch is input as a first signal to the control unit 11 via the remote control receiving unit 12 ( Step S203).

  When it is detected that the first signal is input to the control unit 11 (Yes in step S203), the control unit 11 signals the light source unit 15 regardless of the information signal of the first signal. The operation is shifted to a waiting operation (step S204).

  Here, the signal waiting operation is a certain preset operation that is performed by the light source unit 15 when the first signal is input, regardless of the information signal of the first signal. Say. That is, during the awakening operation, when any signal (first signal) is input, the light source unit 15 is temporarily shifted to a signal waiting operation, and the light source unit 15 immediately performs an operation according to the signal. I am trying not to. In the present embodiment, as shown in FIG. 6, in the signal waiting operation, the main light source 151 is turned off, and the auxiliary light source 152 is turned on with the illuminance L11 set before the start of the awakening operation. Therefore, for example, even if the all-light switch or the illuminance increase switch is pressed due to an erroneous operation by the operator, the illuminance does not increase suddenly, the illuminance decreases, and comfortable awakening is not hindered. .

  On the other hand, if it is not detected in step S203 that the first signal has been input (No in step 203) and it is detected that the time t3 when the awakening operation ends (Yes in step S210), The awakening operation is terminated (step S211), and the lighting state at the end of the awakening operation is maintained (step S212).

  Then, after the light source unit 15 is shifted to the signal waiting operation, the signal waiting operation is continued for a predetermined time h that is a preset time, that is, the time from the time t5 when the first signal is input to the time t6. When the longest time is set (90 seconds in this embodiment) and it is detected that the specified time h has elapsed (Yes in step S205), the first signal is assumed to be an erroneous operation of the remote control by the operator, etc. FIG. As shown, at time t6 after the lapse of the specified time h, the auxiliary light source 152 is turned off, the main light source 151 is turned on again, and the awakening operation is resumed (step S206).

  As shown in FIG. 6, the illuminance of the main light source 151 when returning to the wake-up operation is not the illuminance L25 at t5 when the wake-up operation has shifted to the signal waiting operation by the first signal, but the wake-up operation continues from t2 to t6. Illuminance L26 in the case of As an example of such control, for example, the control unit 11 causes the elapsed time from the lighting start time t2 of the main light source 151 to be counted, and the illuminance corresponding to the elapsed time from the lighting start time t2 of the main light source 151 is stored. When returning from the signal waiting operation to the awakening operation, the illuminance L26 corresponding to t6 is referred to, the main light source 151 is turned on with the illuminance L26, and the illuminance is gradually increased again to the high illuminance over time. In this way, the illuminance of the main light source 151 is such that the illuminance of the main light source 151 is relative to the elapsed time from the lighting start time t2 of the main light source 151 regardless of whether or not the awakening operation has shifted to the signal waiting operation. Since the illuminance is determined, the illuminance of the main light source 151 can be easily determined. Then, the illuminance of the main light source 151 can be increased toward the preset wake-up time t4, and the sleeper can be changed from a deep sleep state to a shallow sleep state regardless of an erroneous operation of the remote control by the operator. Can lead.

  On the other hand, before the specified time h elapses (No in step 205), any switch such as a switch for turning on / off the light source of the light source unit 15 or a switch for changing (dimming) the illuminance of the light source is provided. When operated by the operator, a signal corresponding to the operated switch (information such as turning on / off the light source, changing illuminance (dimming), etc.) is sent to the control unit 11 via the remote control receiving unit 12 as a second signal. (Yes in step S207). When it is detected that the second signal is input to the control unit 11 at time t7, the control unit 11 determines that it is an intentional operation of the remote controller by the operator, as shown in FIG. The operation is terminated and the awakening operation is terminated (step S208), and the light source unit 15 is controlled to follow the second signal (step S209). FIG. 7 shows an operation when the second signal for turning on the main light source 151 is input.

  Note that if the wake-up time t4 is reached without the second signal being input during the stipulated time h of the signal waiting operation, the illuminance may be switched to the maximum illuminance L23 when the wake-up time t4 is reached. It may be configured to switch to the maximum illuminance L23 after the time h has elapsed.

  Also, as shown in FIG. 8, when returning from the signal waiting operation to the awakening operation, the main light source 151 is turned on again at the time t6 with the same illuminance as the illuminance L25 at the time t5 when the first signal was input. Also good. In that case, the illuminance of the main light source 151 is gradually increased so that the maximum illuminance is reached by time t3 one minute before the wake-up time t4.

  In this way, even if a first signal, which is some signal, is input by operating the remote controller 20 during the awakening operation, the control unit 11 does not immediately perform control according to the first signal and outputs the first signal. The control according to the second signal is performed only when the second signal is input within the specified time h (during the signal waiting operation) after the receipt.

  For this reason, when the operation of the remote controller 20 is intentionally performed by the operator instead of an erroneous operation, the control according to the operation of the remote controller 20 is performed by performing the operation of the remote controller 20 again after the first operation of the remote controller 20. Can be performed. Since the auxiliary light source 152 is turned on even after the operation of the first remote controller 20 is performed, the space in which the lighting device 1 is installed does not become dark and the operator can switch the remote controller 20 or the like. Can be visually recognized.

  On the other hand, when the operation of the remote controller 20 is an operator's erroneous operation or the like, the illuminance does not increase rapidly due to the operation. Then, since the operation returns to the awakening operation again after the lapse of the specified time h (after the end of the signal waiting operation) after the erroneous operation or the like, the erroneous operation or the like is canceled. During the awakening operation, the operator is in the process of being awakened, so that an erroneous operation of the remote controller 20 is likely to occur. However, during the awakening operation, only when the next operation of the remote control 20 is continuously performed within the specified time h. In this case, it is assumed that the operation of the remote controller 20 is not an erroneous operation, and an operation according to the operation of the remote controller 20 is performed. Thereby, the operation | movement which inhibits comfortable awakening by the misoperation of the remote control 20 can be prevented.

  In this embodiment, the main light source 151 is turned off and the auxiliary light source 152 is turned on during the signal waiting operation. However, during the signal waiting operation, the lighting control may be performed so that the illuminance does not increase rapidly. For example, the illuminance of the main light source 151 that has been lit during the awakening operation may be reduced with the start of the signal waiting operation to recognize that the transition from the awakening operation to the signal waiting operation has occurred.

  In the second embodiment, the light source unit 15 includes the main light source 151 and the auxiliary light source 152, and the light source unit 15 includes the main light source 151. However, the light source unit 15 includes only the main light source 151. Also good. That is, it is possible to perform a wake-up operation by changing only the main light source 151 from low illuminance to high illuminance, and shift to a signal waiting operation when the first signal is input.
