Description

  The present invention relates to a lighting device and a control program for the lighting device, and more particularly, to a lighting device and a control program for the lighting device that can wake a sleeper.

  Conventionally, an illuminating device that operates in a preset alarm mode when a sleeping user (sleeper) wakes up and has an alarm function that prompts the user to wake up by gradually changing the illuminance of the sleeping space from the set time. Are known.

  Patent Document 1 listed below discloses an illumination device having an alarm function as described above. When receiving a control signal for increasing the light output during operation in the alarm mode, the lighting device stops the alarm mode and changes the light output based on the control signal.

  In Patent Document 2 below, when an increase button for increasing the illuminance is operated after the alarm start time in the illumination device, the alarm mode is continued and the illuminance of the illumination unit is increased until the illuminance exceeds the high illuminance. It is disclosed to maintain the illuminance and control the illuminance of the lighting unit to the illuminance of the increase pattern of the alarm mode after the time when the illuminance becomes higher than the high illuminance. In other words, the lighting device substantially suspends the wake-up mode once the increase button is operated, and then returns to the original wake-up mode again. Patent Document 2 discloses that when a reduction button for reducing the illuminance is operated, the alarm mode is stopped and the illuminance of the illumination unit is controlled to be low.

For example, there are cases where the user wants to turn on all the lights by increasing the illuminance over a certain period of time, although it is more rapid than the preset alarm mode.

  However, as described above, for example, in an illumination device as described in Patent Document 1, only one preset alarm mode is prepared. Therefore, during the execution of the wake-up mode, the user has only room to choose between continuing the wake-up mode or canceling the wake-up mode, and satisfying the above needs.

However, in the lighting device described in Patent Document 1, when a signal for changing the illuminance is input, the alarm mode is canceled and the illuminance corresponding to the signal is instantaneously switched, After that, the illuminance cannot be expected to change gradually by the alarm mode.

  Further, for example, in a lighting device as described in Patent Document 1, when a full lighting signal for making a full lighting state is input, the lighting device is instantaneously turned on and the illuminance is maximized. In this case, it becomes too bright before the user wakes up firmly, which may cause discomfort and stress to the user.

  In the setting unit 24, for example, a button group for setting time and the like is arranged. The buttons of the setting unit 24 are used, for example, for setting an alarm mode timer together with the alarm timer button 27 and the like.

  The dimming instruction section 25 is provided with a group of control signal buttons for inputting a command for outputting each of a plurality of specific control signals to the transmitter 20. The plurality of specific control signals can be used even when an alarm mode described later is executed, and are predetermined. In other words, the plurality of specific control signals are included in a predetermined control signal group.

  In the present embodiment, the control signal button group of the dimming instruction unit 25 is provided with a full lighting button 25a, an extinguishing button 25b, a dimming increase button 25c, and a dimming reduction button 25d. When the all lighting button 25a is operated, the transmitter 20 outputs a whole lighting signal for lighting all the LED modules 14. When the turn-off button 25b is operated, a turn-off signal for turning off the LED module 14 is output from the transmitter 20. When the dimming increase button 25 c is operated, a dimming increase signal for increasing the illuminance by the LED module 14 is output from the transmitter 20. When the dimming reduction button 25d is operated, a dimming reduction signal for reducing the illuminance by the LED module 14 is output from the transmitter 20. In other words, in the present embodiment, the predetermined control signal group includes four controls related to dimming of the LED module 14, that is, the full lighting signal, the extinction signal, the dimming increase signal, and the dimming reduction signal. The signal is included.

  The security light dimming button 26 is used to input a command for increasing or decreasing the light output of the safety light unit 15. When the safety light dimming button 26 is operated, a security light dimming increase signal for increasing the light output of the safety light unit 15 or a security light dimming reduction signal for reducing the light output of the safety light unit 15 is obtained.

For example, a wake-up mode timer can be set on the basis of the time set by the setting unit 24, and the wake-up mode timer can be canceled or reset. When the alarm timer button 27 is operated, for example, an alarm timer signal for switching between operating the timer at a set time or canceling the alarm mode is sent to the illumination unit 10. In the illumination unit 10, the alarm timer signal is received by the remote control receiver 11, and the operation control unit 12 performs control related to the alarm mode operation such as setting or canceling the alarm mode timer based on the alarm timer signal.

  In contrast to the buttons 25a, 25b, 25c, and 25d of the dimming instruction unit 25 for outputting control signals included in the predetermined control signal group as described above, a security light dimming button 26 and an alarm timer button 27 is to output a control signal that does not belong to a predetermined control signal group.

  When the buttons 25a, 25b, 25c, 25d, the security light dimming button 26, etc. of the dimming instruction unit 25 are operated, a control signal corresponding to the operated button as described above is sent to the illumination unit 10. In the illumination unit 10, the control signal is received by the remote control reception unit 11, and the operation control unit 12 sends an operation control signal to the LED drive circuit 13 based on the control signal. Thereby, the lighting state of the LED module 14 and the security light unit 15 is controlled based on the control signal received by the remote control receiving unit 11. When the buttons 25a, 25b, 25c, and 25d of the dimming instruction unit 25 are operated and a control signal related to dimming is output, the operation control unit 12 changes the light output of the LED module 14 according to the control signal. .

  [Explanation of alarm function]

  The lighting device 1 has an alarm function. In the alarm function, when the user who is asleep (sleeping person) gets up, the illuminance of the sleeping space is gradually changed from the set time according to a preset alarm mode, and the illuminance is increased to a predetermined illuminance. Can wake up. The wake-up function is realized by the operation control unit 12 executing a predetermined control program 12a and controlling the operation mode as the wake-up mode. That is, the operation control unit 12 controls the light output of the LED module 14 according to the wake-up mode being executed, thereby changing the illuminance by the LED module 14 and realizing the wake-up function.

  Here, in the present embodiment, the operation control unit 12 has a plurality of alarm modes as operation modes. As will be described later, the plurality of alarm modes include a standard alarm mode (an example of a first alarm mode) and second to fifth alarm modes. When performing the alarm function, the operation control unit 12 performs control using one of a plurality of alarm modes as an operation mode. When performing the alarm function, the operation control unit 12 shifts the operation mode to one of a plurality of alarm modes according to a predetermined trigger, and continues control of the alarm function.

  In each of the plurality of alarm modes, the light output of the LED module 14 to the operation controller 12 is changed so that the illuminance by the LED module 14 changes in the period until the illuminance by the LED module 14 reaches a predetermined illuminance. Control. In the first embodiment, when each of the plurality of alarm modes is executed, there is almost no period in which the increase / decrease rate of illuminance by the LED module 14 is zero, and the light output of the LED module 14 is increased / decreased almost always. . As will be described later, in each of the plurality of alarm modes, the light output of the LED module 14 is adjusted so that the increase / decrease rate of the illuminance is substantially constant and the illuminance gradually increases or decreases, that is, the illuminance gradually changes. It is something to control.

  In the following description (including descriptions of other embodiments), the LED module 14 may be referred to as a light source, and the operation control unit 12 may be simply referred to as a control unit. In addition, each of the control signals included in the predetermined control signal group (a full lighting signal, dimming increase signal, dimming reduction signal, extinguishing signal, etc.) may be collectively referred to as a specific control signal. Further, the illuminance by the LED module 14 may be simply referred to as illuminance.

  In the present embodiment, the wake-up function is started when the control unit shifts the operation mode to the standard wake-up mode among the plurality of wake-up modes when the time preset by the user or the like is reached. In a normal time when there is no special instruction from the user, the wake-up function is performed based on the standard wake-up mode and then ends.

  Here, the control unit detects when a specific control signal is input during operation in the standard wake-up mode. When the input of the specific control signal is detected during the operation in the standard wake-up mode, the operation mode is shifted. As the operation mode to be shifted to, a mode corresponding to the input specific control signal that is different from the standard alarm mode being executed is selected from among a plurality of alarm modes provided in advance. That is, when a specific control signal is input during operation in the standard wake-up mode, the control unit shifts the operation mode from the standard wake-up mode to the wake-up mode corresponding to the input specific control signal.

  FIG. 5 is a flowchart for explaining an example of the alarm function.

  As shown in FIG. 5, when the alarm function starts, in step S11, the control unit determines whether or not a set time has arrived. Until the set time comes, the operation in the previous operation mode is continued. For example, the wake-up function is started after the lighting device 1 is turned off, for example, when the user goes to bed. The operation mode until the wake-up function is started is, for example, a normal operation mode in which a control signal for turning on the lighting device 1 is received and the light output of the light source is controlled in accordance with the received control signal.

  When the set time comes in step S11, in step S12, the control unit shifts the operation mode to the standard wake-up mode. Thereby, lighting of the illumination part 10 by a wake-up function is started.

  In step S13, the control unit controls the light output of the light source so that the illuminance becomes a predetermined first illuminance. The first illuminance is illuminance in a low illuminance area as described later.

  In step S14, the control unit controls the light output of the light source in the standard wake-up mode, and changes the illuminance.

  In step S <b> 15, the control unit detects whether or not a specific control signal is input by the remote control reception unit 11 that is a detection unit.

  When the input of the specific control signal is not detected in step S15, in step S16, the control unit determines whether or not a predetermined time has elapsed since the set time has come. At this time, the control unit determines whether or not the control is performed so that the illuminance becomes the second illuminance higher than the first illuminance, instead of determining whether or not the predetermined time has elapsed. It may be.

  When the predetermined time has elapsed in step S16, in step S17, the control unit ends the standard alarm mode. Thereby, the alarm function is terminated. When the standard wake-up mode ends, the control unit shifts the operation mode to, for example, the normal operation mode as described above. When the operation mode is shifted, for example, illumination is continuously performed with the illuminance when the standard wake-up mode ends.

  Here, in step S15, when the input of the specific control signal is detected during the period until the predetermined time elapses in step S16, that is, during the operation in the standard alarm mode, the process of step S18 is performed. That is, in step S18, the control unit shifts the operation mode to the alarm mode corresponding to the specific control signal input from the standard alarm mode by the transfer program (transfer means) defined by the control program 12a.

  In step S <b> 19, the control unit performs control in the alarm mode corresponding to the input specific control signal that has been transferred. The light output of the light source is controlled so that the illuminance changes based on the shifted alarm mode. Thereafter, when the control in the shifted alarm mode ends, the process proceeds to step S17, and the alarm function ends.

  [Description of Alarm Mode and Operation Example of Lighting Device 1]

  Below, each alarm mode and operation | movement of the illuminating device 1 at the time of the execution are demonstrated.

  FIG. 6 is a graph for explaining the wake-up mode in the first embodiment of the present invention.

  FIG. 6 shows an example of the relationship between the passage of time and the illuminance when the alarm mode is executed. In FIG. 6, A1 is a period during which the standard wake-up mode is performed (corresponding to “predetermined time (step S16)” in FIG. 5), L1 is an illuminance in the low illuminance area (an example of the first illuminance, 1 (corresponding to step S13) ", L4 is the illuminance at the time of transition to the alarm mode, L11 is the illuminance in the high illuminance area (an example of the second illuminance, an example of the predetermined illuminance), and Lm is all lit L0 indicates the illuminance when the light is turned off.

  In FIG. 6, T1 indicates the start time of the standard wake-up mode (corresponding to “set time (step S11)” in FIG. 5), and T2 indicates the time when the specific control signal is input (wake-up mode transition timing). T4 is the end time of the fifth wake-up mode (light-off time), T5 is the end time of the second wake-up mode (all lighting time), T11 is the end time of the third wake-up mode (illuminance is L11) T15 indicates the end time of the standard alarm mode (time when the illuminance becomes L11), and T17 indicates the fourth alarm mode end time (time when the illuminance becomes L11).

  Assume that the lighting device 1 is set to start the alarm function when a predetermined start time T1 is reached. In this case, as shown in FIG. 6, until the start time T1 arrives, for example, the light source is turned off according to the user's operation, and the user can sleep comfortably. When the light source is in the off state at time T0 before the start time T1, the illuminance is substantially zero (L0) at least from time T0 to time T1, as shown in FIG. If an operation for turning on the light source is performed during this period, the light source is turned on.

  [Standard alarm mode]

  At time T1, the control unit shifts the operation mode to the standard wake-up mode (first wake-up mode). Thereby, control of the light output of the light source by the alarm function is started. In FIG. 6, the relationship between the time and the illuminance in the standard wake-up mode is indicated by a solid line and a broken line indicated by a symbol a.

  In the standard wake-up mode (a), when the predetermined period A1 elapses, the control unit performs control so that the illuminance reaches from the illuminance L1 in the low illuminance area to the illuminance L11 in the high illuminance area higher than that. . The period A1 is an operation period in the standard wake-up mode.

  Note that the illuminance L1 in the low illuminance region and the illuminance L11 in the high illuminance region may be set as appropriate. For example, the user may operate the transmitter 20 to set at least one of the illuminances L1 and L11 in advance.

  When the operation mode shifts to the standard wake-up mode at time T1, the light source is turned on with a very small light output, and the illuminance increases from L0 to L1 in the low illuminance region. In the first embodiment, the standard wake-up mode is started from a state where the illuminance is L1 at time T1. The illuminance monotonously increases at a substantially constant increase rate, and is set such that the illuminance reaches L11 at time T15 after the period A1 from time T1. In other words, the standard wake-up mode is an operation mode in which control is performed to change the light output of the light source so that the illuminance gradually increases from time T1 to time T15 until the illuminance reaches L11.

  Here, the control unit stores in advance a plurality of alarm modes corresponding to the type of the specific control signal. When the specific control signal output from the transmitter 20 is input to the illumination unit 10 during execution of the standard alarm mode, the control unit selects the alarm mode corresponding to the specific control signal. In other words, the wake-up mode that is the transition destination differs depending on the specific control signal input during operation in the standard wake-up mode. When the operation mode of the control unit changes, the LED module 14 is controlled to be lit in the operation mode of the alarm mode via the LED drive circuit 13.

  Next, assuming that a specific control signal is input at time T2 after a predetermined time from time T1, as shown in FIG. 6, operations performed for each type of specific control signal will be described. Note that, since the standard wake-up mode is executed from time T1 to time T2, the illuminance that was L1 at time T1 is increased to L4 at time T2.

  [Second alarm mode]

  When the full lighting signal is input, the control unit shifts the operation mode to the second alarm mode corresponding to the full lighting signal. In FIG. 6, the relationship between the time and the illuminance in the second alarm mode is indicated by a solid line indicated by a symbol b.

  The second wake-up mode (b) is an operation mode for controlling the light output of the light source so that the illuminance increases at a higher rate than the standard wake-up mode and reaches the fully lit illuminance Lm. As shown in FIG. 6, when the mode is shifted to the second wake-up mode, the speed at which the illuminance increases is higher than before (the slope of the solid line indicated by the symbol b on the graph increases). Then, after reaching the predetermined illuminance L11 substantially before time T15, the lighting state is fully turned on at time T5, and the illuminance reaches the illuminance Lm of full lighting. When the illuminance reaches Lm, the operation mode is shifted from the second alarm mode to the normal operation mode, and the alarm function is terminated. After time T5, the full lighting state is continued until an instruction from the user or the like is performed, or dimming by a timer or the like is performed.

  The second wake-up mode is effective, for example, when the user who is asleep and wakes up during the execution of the standard wake-up mode wants to wake up comfortably by quickly increasing the illuminance and making it fully lit. It is an operation mode. That is, in the second wake-up mode, it takes some time to reach the full lighting state, and the full lighting state is not instantaneously reached. Therefore, it is possible to prevent the user from feeling dazzling and uncomfortable.

  [Third alarm mode]

  When the dimming increase signal is input, the control unit shifts the operation mode to the third wake-up mode corresponding to the dimming increase signal. In FIG. 6, the relationship between the time in the third wake-up mode and the illuminance is indicated by a solid line indicated by reference sign c.

  In the third wake-up mode (c), the illuminance increases at a higher rate than the standard wake-up mode, and reaches the predetermined illuminance L11, that is, the illuminance that was scheduled to be reached in the standard wake-up mode. This is an operation mode for controlling the light output of the light source. As shown in FIG. 6, when the mode is shifted to the third alarm mode, the speed at which the illuminance increases becomes higher than before, and the illuminance reaches a predetermined illuminance L11 at time T11 considerably before time T15. When the illuminance reaches L11, the operation mode is shifted from the third alarm mode to the normal operation mode, the alarm function is terminated, and the lighting state is continued.

  Here, the increase rate of the illuminance at the time of execution of the third wake-up mode is set to be lower than the increase rate of the illuminance at the time of execution of the second wake-up mode, but is not limited thereto. . In addition, even if the illuminance increase rate is set so that the third wake-up mode ends and the illuminance at that time becomes L11 when a predetermined time has elapsed since the operation mode became the third wake-up mode. Good.

  The third wake-up mode is effective when a user who is asleep and wants to wake up comfortably by increasing the illuminance to a predetermined illuminance earlier than usual when he / she is asleep while executing the standard wake-up mode. It is. Although the speed at which the illuminance increases to a predetermined illuminance is higher than when operating in the standard alarm mode, the illuminance does not increase instantaneously. Therefore, it is possible to prevent the user from feeling uncomfortable by the alarm mode.

  [Fourth alarm mode]

  When the dimming reduction signal is input, the control unit shifts the operation mode to the fourth alarm mode corresponding to the dimming reduction signal. In FIG. 6, the relationship between the time and the illuminance in the fourth alarm mode is indicated by a solid line indicated by a symbol d.

  The fourth wake-up mode (d) is an operation mode for controlling the light output of the light source so that the illuminance increases at a lower increase rate than the standard wake-up mode and reaches a predetermined illuminance L11. As shown in FIG. 6, when shifting to the fourth alarm mode, the speed at which the illuminance rises is lower than before (the slope of the solid line indicated by the symbol d on the graph is smaller), and from time T15 The illuminance reaches a predetermined illuminance L11 at a later time T17. When the illuminance reaches L11, the operation mode is shifted from the fourth alarm mode to the normal operation mode, the alarm function is terminated, and the lighting state is maintained.

  The fourth wake-up mode is effective when, for example, the user who is asleep and wants to secure a little longer time to wake up than the original schedule when the user wakes up while executing the standard wake-up mode. It is. With a simple operation, the time to reach the predetermined illuminance L11 can be delayed while the illuminance is gradually increased.

  [Fifth alarm mode]

  When the turn-off signal is input, the control unit shifts the operation mode to the fifth alarm mode corresponding to the turn-off signal. In FIG. 6, the relationship between the time and the illuminance in the fifth alarm mode is indicated by a solid line indicated by a symbol e.

  The fifth alarm mode (e) is an operation mode for controlling the light output of the light source so that the illuminance is reduced at a predetermined reduction rate and reaches the illuminance L0 when the light is turned off. As shown in FIG. 6, when the mode is shifted to the fifth wake-up mode, the illuminance gradually decreases monotonically and at a constant reduction rate as time passes until the illuminance changes from L4 to L0 (graph). (A solid line with a negative slope indicated by the symbol e above). At time T4 after time T2, the light source is turned off and the illuminance becomes L0. When the illuminance becomes L0, the operation mode is shifted from the fifth alarm mode to the normal operation mode, and the alarm function is terminated.

  The fifth wake-up mode is a case where the user who has gone to sleep considers to stop waking up at the originally scheduled wake-up time during the execution of the standard wake-up mode, that is, when the wake-up time is not specified. This is an effective operation mode. At this time, it is not instantaneously turned off with the reception of the control signal, but is configured so as to gradually decrease the illuminance by providing an inclination until the light is turned off. The effect of encouraging the user to sleep by darkening the sleeping environment can be expected.

  As described above, in the first embodiment, the operation mode is shifted to another alarm mode based on the specific control signal transmitted during the operation in the standard alarm mode. Therefore, when the lighting device 1 is operating in the standard wake-up mode, the user operates the transmitter 20 or the like to perform a desired operation, thereby changing the illuminance in various modes and using the wake-up function. be able to. The user can shift the lighting device 1 to the desired wake-up mode according to the situation when the user wakes up (for example, the time when the user wakes up, the state of the user's mood, physical condition, etc.). Therefore, the user can wake up comfortably using the alarm function.

  In the first embodiment, each of the second to fifth alarm modes is an operation mode in which control is performed to change the light output of the light source so that the illuminance gradually changes until the illuminance reaches a predetermined illuminance. . Therefore, when the specific control signal is input, the illuminance does not change instantaneously, so that the user does not feel a sudden change in illuminance. As a result, it is possible to provide an alarm function that can be comfortably used by the user.

  [Second Embodiment]

  Since the basic configuration of the illumination device in the second embodiment is the same as that in the first embodiment, description thereof will not be repeated here. In the second embodiment, the operation of the control unit when a specific control signal is input while operating in the standard wake-up mode is different from that in the first embodiment.

  In the second embodiment, when a specific control signal is input during operation in the standard wake-up mode, the control unit determines the illuminance during execution of the wake-up mode after the transition according to the time when the specific control signal is input. Change the rate of change.

  FIG. 7 is a graph for explaining the wake-up mode in the second embodiment of the present invention.

  In FIG. 7, as a specific example of the second embodiment, a relationship between time and illuminance when a full lighting signal is input as a specific control signal is shown. The solid line indicated by reference sign b1 indicates the relationship between time and illuminance in the second alarm mode executed when the full lighting signal is input at time T2. A solid line indicated by reference sign b4 indicates the relationship between time and illuminance in the second alarm mode executed when the full lighting signal is input at time T8 after time T2.

  As shown in FIG. 7, when the full lighting signal is input at time T2, the operation mode shifts to the second alarm mode (b1) in which the inclination angle is α1 when the change in illuminance is shown in the graph. At time T5, the fully illuminated illuminance Lm is reached. α1 is an angle larger than the inclination angle of the straight line indicating the standard alarm mode (a). That is, the illuminance increase rate in the second wake-up mode (b1) shifted to time T2 is larger than the illuminance increase rate in the standard wake-up mode.

  On the other hand, when the full lighting signal is input at time T8 later than time T2, the operation mode is changed to the second wake-up mode (b4) in which the inclination angle is α2 larger than α1 when the change in illuminance is shown in the graph. The illuminance Lm is fully lit at time T12. That is, the increase rate of the illuminance in the second wake-up mode (b4) shifted to time T8 is larger than the increase rate of the illuminance in the second wake-up mode (b1) transferred to time T2.

  In this way, the rate of increase in illuminance increases as the full lighting signal is input at a later time, thereby reducing the time required to reach the full lighting illuminance Lm after the signal is input. Therefore, for example, it is particularly effective for the need to quickly increase the illuminance as the awakening time is later.

  Note that the second embodiment can also be applied to a specific control signal other than the full lighting signal. Depending on the type of the specific control signal, the tilt angle may be set to be gentler as it is input later. Further, even if the same specific control signal is used, the tilt angle may be set to be gentler as it is input at a later time if necessary. In the second embodiment, when a specific control signal is sent by the user's operation, the illuminance can be changed according to the operation timing, and the alarm function is executed in a manner that meets the user's needs. be able to.

  [Third Embodiment]

  Since the basic configuration of the illumination device in the third embodiment is the same as that in the first embodiment, the description here will not be repeated. In the third embodiment, the operation of the control unit after the specific control signal is input when operating in the standard wake-up mode is different from that in the first embodiment.

  FIG. 8 is a graph for explaining the alarm mode in the third embodiment of the present invention.

  In the third embodiment, as in the first embodiment described above, when a specific control signal is input during operation in the standard alarm mode, the operation mode is set to the alarm mode corresponding to the specific control signal. To be migrated. Here, during execution of the alarm mode corresponding to the specific control signal, the control unit performs control to change the increase / decrease rate of illuminance according to the number of times the specific control signal is input.

  As shown in FIG. 8, when the specific control signal is input at time T2 during execution of the standard wake-up mode (a), for example, the second wake-up mode (b1) is set as the wake-up mode corresponding to the specific control signal. The operation mode shifts to the third alarm mode (c1), the fourth alarm mode (d1), and the fifth alarm mode (e1). At this time, whenever the specific control signal corresponding to the alarm mode being executed is input, the control unit increases the illuminance according to the input specific control signal, that is, according to the alarm mode being executed. Increase or decrease. For example, every time a full lighting signal corresponding to the second wake-up mode is input, the illuminance change mode in the second wake-up mode is changed from the sign b1 to the sign b2 in FIG. 8 (when the second signal is input). ), The code b2 is changed to the code b3 (when the third signal is input). The operation during execution of the other alarm modes is the same as this.

  In the present embodiment, when the alarm mode in which the increase rate of illuminance is large compared with the increase rate of illuminance in the standard wake-up mode is being executed, every time a specific control signal corresponding to the wake-up mode is input The illuminance increase rate is controlled to be large. On the other hand, when a wake-up mode (including a wake-up mode in which the illuminance increase rate is negative) is being executed with a small illuminance increase rate compared to the illuminance increase rate in the standard wake-up mode, the specific corresponding to the wake-up mode Each time a control signal is input, the illuminance increase rate is controlled to decrease. More specifically, when the full lighting signal or the dimming increase signal is repeatedly input, the increase rate of the illuminance in the second alarm mode or the third alarm mode increases each time the signal is input (see FIG. As shown in FIG. 8, the slope of the straight line indicating the change in illuminance increases in the order of the symbols b1, b2, b3, or the order of the symbols c1, c2, c3. In addition, when the dimming reduction signal is repeatedly input, the increase rate of the illuminance in the fourth wake-up mode decreases each time the signal is input (as shown in FIG. 8, the signs d1, d2, and d3). In turn, the slope of the straight line indicating the change in illuminance decreases.) Further, when the turn-off signal is repeatedly input, the increase rate of the illuminance in the fifth alarm mode decreases every time the signal is input. In other words, the decrease rate of illuminance increases (as shown in FIG. 8, the slope of the straight line indicating the change in illuminance increases in the negative direction in the order of the symbols e1, e2, and e3).

  In the third embodiment, the user can change the increase / decrease rate according to the number of times of input of the specific control signal. Therefore, when each alarm mode is executed, the end time of the alarm mode can be adjusted according to the user's desire. The user can execute various alarm modes in a manner more reflecting his / her intention.

  Note that the change in the increase / decrease rate is not limited to the example shown in FIG. For example, each wake-up mode may be configured such that the illuminance increase rate increases each time a specific control signal corresponding thereto is input.

  [Fourth Embodiment]

  Since the basic configuration of the illumination device in the fourth embodiment is the same as that in the first embodiment, description thereof will not be repeated. In the fourth embodiment, the operation of the control unit when a specific control signal is input while operating in the standard wake-up mode is different from that in the first embodiment.

  FIG. 9 is a graph for explaining the alarm mode in the fourth embodiment of the present invention.

  In the fourth embodiment, when a specific control signal is input during operation in the standard wake-up mode, the illuminance is increased or decreased corresponding to the specific control signal after the illuminance at the input time of the specific control signal increases or decreases by a predetermined value. The operation mode is shifted to a wake-up mode in which the light output of the light source is controlled so as to change. Here, the increase or decrease in illuminance at a specific time is instantaneously performed in a relatively short time. The increase / decrease value of the illuminance is, for example, a value set in advance as corresponding to the input specific control signal. In addition, when the specific control signal is input during the execution of the wake-up mode thus shifted, the transition of the operation mode as described above is repeatedly performed.

  As shown in FIG. 9, after the operation of the standard wake-up mode (a) is started at time T1, a dimming increase signal that is a specific control signal is input at time T2 (first input), and the subsequent time Assume that the input is made again at T3 (second input). By performing the operation of the standard wake-up mode (a) until time T2, the illuminance at time T2 is L4.

  When the first dimming increase signal is input at time T2, the operation mode is shifted to the sixth alarm mode (c4). In the fourth embodiment, the sixth alarm mode is a predetermined increase corresponding to the dimming increase signal after the illuminance at the input time of the dimming increase signal is increased by a predetermined value (a value obtained by subtracting L4 from L6). The light output of the light source is controlled so that the illuminance changes at a rate (same as the rate of increase in the standard wake-up mode in this embodiment). That is, when the dimming increase signal is input at time T2, the light output of the light source is changed so that the illuminance increases from L4 to L6 at time T2 as a result of the operation mode being shifted. After time T2, control is performed so that the illuminance changes from L6 at the same increase rate as the increase rate in the standard alarm mode. By performing the control in the sixth alarm mode, the illuminance increases to L7 at time T3.

  When the second dimming increase signal is input at time T3 during execution of the sixth wake-up mode (c4), the operation mode is again shifted to the sixth wake-up mode (c5). In other words, when the dimming increase signal is input for the second time, the operation from the transition to the sixth alarm mode is performed again. That is, when the operation mode is shifted, the light output of the light source is changed so that the illuminance increases from L7 to L8 at time T3. The increase in illuminance at this time is the same as the increase from L4 to L6. Then, after time T3, control is performed so that the illuminance changes from L8 at the same increase rate as the increase rate in the standard alarm mode. By performing the control in the sixth alarm mode as described above, the illuminance reaches L11 which is a predetermined illuminance at time T10. When the illuminance reaches L11, the operation mode is shifted from the sixth alarm mode to the normal operation mode, the alarm function is terminated, and the lighting state is continued. If the dimming increase signal is further input before the illuminance reaches L11, the operation mode is again shifted to the sixth alarm mode.

  On the other hand, it is assumed that a dimming reduction signal that is a specific control signal is input at time T2 (first input) and then input again (second input) at time T9 thereafter.

  When the first dimming reduction signal is input at time T2, the operation mode is shifted to the seventh alarm mode (d4). In the fourth embodiment, the seventh wake-up mode has a predetermined increase corresponding to the dimming reduction signal after the illuminance at the input time of the dimming reduction signal decreases by a predetermined value (a value obtained by subtracting L2 from L4). The light output of the light source is controlled so that the illuminance changes at a rate (same as the rate of increase in the standard wake-up mode in this embodiment). That is, when the dimming reduction signal is input at time T2, the light output of the light source is changed so that the illuminance decreases from L4 to L2 at time T2 as a result of the operation mode being shifted. Then, after time T2, control is performed so that the illuminance changes from L2 at the same increase rate as that in the standard alarm mode. By performing the control in the seventh alarm mode, the illuminance is L5 at time T9.

  When the second dimming reduction signal is input at time T9 during execution of the seventh wake-up mode (d4), the operation mode is again shifted to the seventh wake-up mode (d5). In other words, when the dimming reduction signal is input for the second time, the operation from the transition to the seventh alarm mode is performed again. That is, when the operation mode is shifted, the light output of the light source is changed so that the illuminance decreases from L5 to L3 at time T9. The amount of decrease in illuminance at this time is the same as the amount of decrease from L4 to L2. Then, after time T9, control is performed so that the illuminance changes from L3 at the same increase rate as that in the standard alarm mode. By performing the control in the seventh alarm mode in this way, the illuminance reaches L11 which is a predetermined illuminance at time T19. When the illuminance reaches L11, the operation mode is shifted from the seventh alarm mode to the normal operation mode, the alarm function is terminated, and the lighting state is continued. If the dimming reduction signal is further input before the illuminance reaches L11, the operation mode is again shifted to the seventh alarm mode.

  In the fourth embodiment, when a transition is made to the alarm mode corresponding to the specific control signal, the illuminance is increased or decreased by a predetermined value when the transition is made, that is, at the input time of the specific control signal. Therefore, the end time of each operation mode, that is, the time when the illuminance reaches L11 can be adjusted earlier or later, or can be adjusted easily and quickly.

  Note that the specific control signal of the fourth embodiment is not limited to the above example, and may be another specific control signal.

  In the above description, the example in which the illuminance increases at the same increase rate as the increase rate of the standard wake-up mode when executing the wake-up mode after the transition to the operation mode is shown, but the present invention is not necessarily limited thereto. That is, the illuminance does not need to increase at the increase rate of the standard wake-up mode. For example, the illuminance may increase at an increase rate specific to each wake-up mode.

  [Fifth Embodiment]

  Since the basic configuration of the illumination device in the fifth embodiment is the same as that in the first embodiment, description thereof will not be repeated. In the fifth embodiment, the operation of the control unit in the case where a specific control signal is repeatedly input while operating in the alarm mode is different from that in the first embodiment.

  FIG. 10 is a graph for explaining the alarm mode in the fifth embodiment of the present invention.

  In the fifth embodiment, as in the first embodiment described above, when a specific control signal is input during operation in the standard wake-up mode, the operation mode is set to the wake-up mode corresponding to the specific control signal. To be migrated. Here, during execution of the alarm mode corresponding to the specific control signal, the control unit detects the input of a specific control signal different from the specific control signal being executed, and further detects the specific control signal. The operation mode is shifted to the corresponding alarm mode.

  As shown in FIG. 10, after the operation of the standard wake-up mode (a) is started at time T1, a dimming increase signal that is a specific control signal is input at time T2, and the specific control is performed at time T6 thereafter. Assume that a full lighting signal as a signal is input.

  When the dimming increase signal is input at time T2, the operation mode is shifted to the third wake-up mode (c). In the third wake-up mode, control is performed such that the illuminance increase rate is higher than the illuminance increase rate in the standard wake-up mode. When the full lighting signal is input at time T6, the operation mode is shifted to the second alarm mode (b). In the second wake-up mode, control is performed so that the illuminance increase rate is higher than the illuminance increase rate in the third wake-up mode. If no other specific control signal is input, the second wake-up mode is continuously performed according to the full lighting signal until the illuminance reaches the full lighting illuminance Lm.

  As described above, in the fifth embodiment, when a specific control signal different from the specific control signal being executed is input even after the transition from the standard alarm mode to the alarm operation mode corresponding to the specific control signal, The operation mode is changed accordingly. Accordingly, even after the transition to the wake-up mode, a preferred wake-up mode can be easily selected according to the desired change of the sleeping user.

  Note that the specific control signal, the control signal, and the like are not limited to the above example. For example, if another specific control signal is input and the alarm mode corresponding to the specific control signal is executed accordingly, Good.

  [Sixth Embodiment]

  Since the basic configuration of the illumination device in the sixth embodiment is the same as that in the first embodiment, the description thereof will not be repeated here. In the sixth embodiment, the operation of the control unit when a control signal is input while operating in the wake-up mode is different from that in the first embodiment.

  FIG. 11 is a graph for explaining the alarm mode in the sixth embodiment of the present invention.

  In the sixth embodiment, when any one of the plurality of alarm modes is executed, when a control signal other than the specific control signal, that is, a control signal not included in the preset control signal group is input, The control unit performs control to stop the operation in the alarm mode being executed. And control according to the control signal input at that time is performed by the control part.

  As illustrated in FIG. 11, for example, a case is assumed where a dimming increase signal that is a specific control signal is input at time T2 after the standard wake-up mode (a1) is started at time T1. At this time, the operation based on the standard wake-up mode (a1) is performed until time T2, and the operation mode is shifted to the third wake-up mode (c) having a higher illuminance increase rate than the standard wake-up mode at time T2. . Here, when, for example, an alarm timer signal (an example of a control signal not included in the control signal group) is input at time T7 during execution of the third alarm mode (c), the control unit The operation of the third alarm mode (c) is stopped. In the present embodiment, when the operation in the wake-up mode is stopped, lighting device 1 is in the same state as that before the wake-up mode is started, that is, the light-off state.

  When the operation in the alarm mode is stopped as described above, the control according to the alarm timer signal input at that time is performed by the control unit. In the sixth embodiment, when a wake-up timer signal is input at time T7, the operation mode is shifted again to the standard wake-up mode after being turned off once as described above. In the standard wake-up mode (a2) started at time T7, the light output of the light source is controlled so that the illuminance reaches L1 to L11 from time T7 to time T20 after the same period A2 as the period A1.

  Such an operation is an example of an operation when a wake-up timer signal is input, and even when a wake-up timer signal is input in the same manner, for example, the standard wake-up mode is not started again. For example, other operations may be performed. Control signals other than the specific control signal are not limited to the alarm timer signal, and a control operation corresponding to the signal may be performed even when other signals are input.

  For example, as examples of control signals other than the specific control signal, in addition to the alarm timer signal as described above, a safety light dimming signal (a safety light dimming increase signal or a safety light dimming reduction signal), an ON-OFF timer A signal, a predetermined time OFF timer signal, a security timer signal, and the like. That is, when the alarm timer signal is input, the alarm clock signal is turned off and the standard alarm mode is executed again. On the other hand, when the security light dimming signal is input, the wake-up mode being executed is canceled and, for example, the LED module 14 is turned off. Then, based on the safety light dimming signal, dimming control of the safety light unit 15 is executed. When an ON-OFF timer signal is input, the timer is set so that it is turned on or off at a specified time after the alarm mode being executed is canceled. When an OFF timer signal is input for a predetermined time, the timer is set so that it turns off after a predetermined time (for example, 30 minutes or 60 minutes) after the alarm mode being executed is canceled. When a security timer signal is input, the security function is started after the active alarm mode is canceled. In the crime prevention function, for example, the lighting device 1 is turned on or off with the arrival of a predetermined time so that the lighting device 1 appears to operate in response to a user operation.

  Also, when a control signal other than the specific control signal is input during execution of the standard wake-up mode, the same operation as described above may be performed.

  Thus, according to the sixth embodiment, even when the alarm mode is being executed, when a control signal other than the specific control signal is transmitted, the alarm mode being executed is canceled and the control signal is handled. Various operations desired by the user can be executed.

  [Seventh Embodiment]

  Since the basic configuration of the illumination device in the seventh embodiment is the same as that in the first embodiment, description thereof will not be repeated. In the seventh embodiment, the operation of the control unit when a specific control signal is input while operating in the standard wake-up mode is different from that in the first embodiment.

  In the seventh embodiment, during operation in the standard wake-up mode, the control unit has a predetermined illuminance (second illuminance) that is scheduled to reach in the standard wake-up mode to a predetermined lower level than that. When the third illuminance is reached, a notification sound (alarm sound) is output (transmitted) from the notification sound transmission unit 16 (output operation of the notification sound). When the control unit receives the specific control signal before the illuminance reaches the third illuminance during the operation in the standard wake-up mode, the control unit outputs the notification sound from the notification sound transmission unit 16 thereafter. Select whether or not to continue. The selection of whether or not to continue the notification sound output operation is performed according to the type of the specific control signal input at that time. Here, the notification sound output operation includes an operation of waiting to output a notification sound when the illuminance reaches a predetermined illuminance.

  FIG. 12 is a graph for explaining the alarm mode in the seventh embodiment of the present invention.

  In FIG. 12, the upper graph is a graph showing the relationship between the illuminance and the time, and three graphs showing the operation of the notification sound transmitter 16 are shown below the graph. As shown in FIG. 12, it is assumed that the standard wake-up mode (a) is started at time T1, as in the first embodiment. Here, in the standard alarm mode, the illuminance is changed from L1 to L11 (an example of the second illuminance, an example of the predetermined illuminance).

  At this time, for example, when the control signal is not input and the standard wake-up mode is continuously performed without shifting the operation mode, the illuminance is L11 as shown in the second graph from the top in FIG. The notification sound is output from time T13 when reaching lower L10 (an example of the third illuminance). The output of the notification sound is stopped, for example, at time T16 when the turn-off signal is input after the illuminance reaches L11 and the standard wake-up mode ends. At this time, the period during which the notification sound is output is a period B1 from time T13 to time T16. When the turn-off signal is input again after the output of the notification sound is stopped, the turn-off is turned off. In the case where the turn-off signal is not input, the notification sound may be stopped when a predetermined period elapses after the output of the notification sound is started. In this case, the notification sound is stopped when the turn-off signal is input within a predetermined period from when the notification sound is output or when the predetermined period has elapsed.

  Thus, in the illuminating device 1, since it will be alert | reported if it becomes the predetermined illumination intensity L10, it can wake up reliably, without oversleeping.

  Here, it is assumed that the full lighting signal, dimming increase signal, dimming reduction signal, or extinguishing signal, which is the specific control signal, is input at time T2. In the seventh embodiment, when the dimming increase signal or the dimming reduction signal is input, the control unit is executing the third alarm mode (c) or the fourth alarm mode (d). Then, the notification sound output operation is continued. On the other hand, when the full lighting signal or the extinguishing signal is input, that is, when the second alarm mode (b) or the fifth alarm mode (e) is being executed, the control unit stops the output operation of the notification sound. Let

  When a dimming increase signal or dimming reduction signal is input at time T2, the operation mode is switched to the third alarm mode (c) and the fourth alarm mode (d), respectively. At this time, the notification sound output operation is continued. That is, for example, when the fourth wake-up mode is executed, when the illuminance reaches L10 at time T14, the notification sound transmitting unit 16 notifies the user as shown in the third graph from the top in FIG. Sound is transmitted. At this time, for example, when the turn-off signal is input at time T18 after the illuminance reaches L11 and the fourth alarm mode ends, the notification sound output is stopped. That is, the period during which the notification sound is output is a period B2 from time T14 to time T18. When the turn-off signal is input again, it is turned off.

  When the full lighting signal or the extinguishing signal is input at time T2, the operation modes are switched to the second alarm mode (b) and the fifth alarm mode (e), respectively. At this time, the notification sound output operation is stopped (cancelled). That is, as shown in the fourth graph from the top in FIG. 12, when the second wake-up mode is executed, the notification sound is transmitted from the notification sound transmission unit 16 even when the illuminance reaches L10. Not. In addition, when the fifth alarm mode is executed, the illuminance decreases monotonously. Therefore, the illuminance does not reach L10 after the operation mode shifts to the fifth alarm mode. Therefore, the notification sound is not transmitted from the notification sound transmission unit 16.

  As described above, in the seventh embodiment, it is possible to urge the user to awaken by increasing the illuminance, and in addition to that, the user can be surely awakened by outputting the notification sound. Even after the transition from the standard wake-up mode to the third wake-up mode or the fourth wake-up mode, the operation of outputting the notification sound is continued, and the notification sound is output when the illuminance reaches L10. Therefore, the user can be surely awakened without sleeping. Since the output of the notification sound can be stopped by transmitting the extinguishing signal when the notification sound is output, the function of outputting the notification sound by an easy operation can be used.

  If the standard wake-up mode is shifted to the second wake-up mode or the fifth wake-up mode before the illuminance reaches the predetermined illuminance L10, the output operation of the notification sound is stopped and the notification sound is not transmitted thereafter. Therefore, the user can prevent an unnecessary notification sound from being sounded after waking up.

  The type of the specific control signal for which the notification sound output operation is continued is not limited to the above, and can be changed as appropriate.
