Japanese Examined Patent Publication No. 4-68595

    By the way, in the alarm device of the above-mentioned patent document 1, when the sleeper is sleeping in a thin state, the light of the lighting device does not effectively act on the sleeper even if the lighting device is turned on, and the sleeper sleeps. The state may be deep even immediately before the awakening device operates. In such a case, the awakening device notifies the sleeping person to wake up, and when the sleeping person suddenly becomes awakening and opens his eyes, the lighting device is lit with the above illuminance increased. There has been a problem of feeling uncomfortable due to the glare of the lighting fixture.

    The present invention has been made in view of the above points, and in an alarm device that illuminates a sleeper by illuminating the lighting means before the scheduled wake-up time and generates an alarm sound at the scheduled wake-up time, An object of the present invention is to improve the comfort of awakening of a sleeper by reducing the glare caused by the illumination means when the eye is awakened by an alarm sound and the eyes are opened.

The first aspect of the invention is a setting means (51) for setting a bedtime scheduled wake-up time (Ta) and an alarm means for generating an alarm sound at the scheduled wake-up time (Ta) set by the setting means (51) ( 30), lighting means (20) for awakening the sleeper, and lighting means (20) from a predetermined time (T1) before the alarm sound generation time (Ta) of the alarm means (30). The first control means (41) for starting and lighting the illumination means (20) at a predetermined illuminance (L1) before the alarm sound occurrence time (Ta) and the alarm sound occurrence time (Ta) of the alarm means (30) ), The second control means (42) for controlling the first control means (41) so that the illuminance of the illumination means (20) is lower than the predetermined illuminance (L1), and the alarm sound of the alarm means (30). Instead of the second control means (42) after the stop time (Ts), the illumination means (20) Degree is provided with a third control means (43) for controlling the first control means (41) to be higher than the intensity of the alarm sound generation time (Ta).

    In the first aspect of the invention, the illuminance of the illumination means (20) is made lower than the predetermined illuminance (L1) at the alarm sound generation time (Ta) of the alarm means (30). That is, the sleeper is in a lean state or the like before the alarm sound generation time (Ta), so that the illumination of the illumination means (20) may not be sufficiently activated and may not be sufficiently induced to the awake state. At that time, even if the sleeper suddenly becomes awake from a deep sleep state due to the generation of an alarm sound, the light supplied from the illumination means (20) does not feel dazzling.

Further, the alarm sound of the alarm means (30) is automatically stopped after a predetermined time has elapsed, or is stopped by a stop button (33) being pressed by a sleeper, and the alarm sound stop time (Ts) The sleeper is awake. Then, after the alarm sound stop time (Ts) when the sleeper is awakened, the illuminance of the lighting means (20) is made higher than the illuminance of the alarm sound generation time (Ta), and sleepiness occurs after the sleeper is awakened. Prevent being triggered.

    In a second aspect based on the first aspect, the second control means (42) stops the lighting means (20) from being turned on at the alarm sound generation time (Ta) of the alarm means (30). The first control means (41) is controlled.

In the second invention, to stop the lighting of the illuminating means (20) to the alarm sound generation time (Ta), you lower than illuminance easily the predetermined illuminance of the illumination means (20) (L1).

In a third aspect based on the first aspect, the illuminating means (20) is configured to generate cold or white light when lit.

In the third aspect of the invention, the cold-colored or white-colored light is light containing a lot of light having a wavelength of around 464 nm (380 nm or more and 525 nm or less), and such light causes sleepiness by stimulating the retina. It is known to suppress inducing melatonin secretion. In the fourth aspect of the invention, since the lighting means (20) generates cold or white light from a predetermined time (T1) before the alarm sound generation time (Ta), the sleeper is in a lean state or the like. even when the light of the illumination means (20) is not only fed very small quantities, the arousal state of the sleeping person that somewhat shallow.

    According to the first aspect of the invention, since the illuminance of the illumination means (20) is made lower than the predetermined illuminance (L1) at the alarm sound generation time (Ta) of the alarm means (30), Even if it is not sufficiently awakened due to a lean state etc. before the alarm sound generation time (Ta), it suddenly awakened from a deep sleep state due to the generation of an alarm sound and opened its eyes At this time, the light supplied from the illumination means (20) does not feel dazzling. This can reduce the uncomfortable feeling caused by lighting of the illumination means (20) when the sleeping person wakes up, so that the sleeping comfort of the sleeping person can be improved.

In addition, since the illuminance of the lighting means (20) is higher than the illuminance of the alarm sound generation time (Ta) after the alarm sound stop time (Ts) of the alarm means (30), Awakening can be made more comfortable without inducing sleepiness. Thereby, it is possible to prevent the sleeping person from sleeping twice after getting up.

According to the second aspect of the invention, since the lighting means (20) is turned off at the alarm sound generation time (Ta), the illuminance of the lighting means (20) is set to the predetermined illuminance (L1). Ru can be more easily reduced.

Further, according to the third aspect, it illuminating means (20) for cold colors or white light is to be generated, a sleeping person is prone state like before alarm occurrence time (Ta) Thus, even if the light supply to the sleeping person is extremely small, the awakening state of the sleeping person can be made slightly shallower. As a result, Ru can be sleeping person is to reduce more discomfort you feel when you wake by the generation of the alarm sound.

    Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

-Driving action-
The operation of the alarm device (10) will be described with reference to FIGS.

    First, before the bedtime of the sleeping person, the sleeping person or the like presses the selection button (52) of the time setting unit (51) to select the scheduled wake-up time (Ta) (for example, 7 o'clock), and the storage unit ( 53) remembers the scheduled wake-up time (Ta). On the display screen (54), the wake-up time display section (52) displays the scheduled wake-up time (Ta).

    When a predetermined time (T1) (for example, 6:30) before the alarm sound generation time (Ta), which is the scheduled wake-up time (Ta), comes to the time setting unit (51) after the sleep start of the sleeper. The notification signal at the predetermined time (T1) is output, and the notification signal at the time (T1) is input to the first control unit (41) of the illumination control unit (40). Thereby, the said 1st control part (41) applies a voltage to an illumination part (20), and makes an illumination part (20) light. The first control unit (41) gradually increases the illuminance of the illumination unit (20) by gradually increasing the applied voltage, and a predetermined time (T2) (eg, 6:00) before the alarm sound generation time (Ta). 40 minutes), the illumination unit (20) is turned on at a predetermined illuminance (L1) (for example, 500 (lx)). In this way, the illuminating unit (20) supplies the sleeping person with light having a predetermined illuminance (L1) to induce the awake state. In this embodiment, the illuminance of the lighting unit (20) is gradually increased to a predetermined illuminance (L1) to prevent the sleeper from suddenly receiving a large light stimulus and feeling uncomfortable. However, the control for lighting at the predetermined illuminance (L1) is not particularly limited, and the light may be lit at the predetermined illuminance (L1) from the time (Ta).

    When the time (Tb) immediately before the alarm sound generation time (Ta) is reached (for example, 6:59 one minute before), the time setting unit (51) outputs a notification signal of the previous time (Tb). And the notification signal of this time (Tb) is input into the 2nd control part (42) of the said illumination control part (40). Accordingly, the second control unit (42) outputs an illuminance reduction signal to the first control unit (41), and the first control unit (41) determines that the illuminance of the illumination unit (40) is the predetermined value. Control is performed so that the illuminance (L2) is lower than the illuminance (L1) (for example, 5 (lx)).

    When the scheduled wake-up time (Ta) is reached, the time setting unit (51) outputs a notification signal of the alarm sound generation time (Ta) that is the expected wake-up time (Ta), and the notification signal of the time (Ta) Is input to the sound source control unit (32) of the alarm unit (30). Accordingly, the sound source control unit (30) outputs an activation signal to the sound source unit (31) and causes the sound source unit (31) to generate an alarm sound. In this way, the bedtime is notified of the scheduled wake-up time (Ta). At this time, since the illumination unit (20) is lit at the low illuminance (L2), the sleep unit is in a lean state or the like before the alarm sound occurrence time (Ta). Even if the light is not sufficiently supplied and is not sufficiently induced to awaken, the sleeper (20) is dazzled by the light of the illumination unit (20) when he awakes and opens his eyes I don't feel it.

    When the stop button (33) is pressed due to the awakening of the sleeping person, a stop signal of the sound source unit (31) is output from the stop button (33) to the sound source control unit (32), while the third control unit ( 43), an alarm sound stop time (Ts) notification signal is output. Thereby, the sound source unit (31) stops the generation of the alarm sound, and at the same time, the third control unit (43) outputs an illuminance increase signal to the first control unit (41), and the illumination unit (20 ) Is controlled to be a predetermined high illuminance (L3) (for example, the same illuminance as L1) higher than the low illuminance (L2).

-Effect of Embodiment 1-
In this embodiment, from the predetermined time (T1) before the alarm sound generation time (Ta) of the alarm unit (30), the lighting unit (20) is turned on and the illuminance of the lighting unit (20) is set to the predetermined illuminance ( L1), and from the time (Tb) immediately before the alarm sound generation time (Ta) to the alarm stop time (Ts), the illuminance of the lighting unit (20) is set to low illuminance (L2) lower than the predetermined illuminance (L1) In addition, even if the sleeper is not sufficiently awakened due to a lean state before the alarm sound generation time (Ta), a sudden awakening from a deep sleep state due to the generation of an alarm sound When the eyes are opened, the light supplied from the illumination unit (20) does not feel dazzling. Thereby, the uncomfortable feeling at the time of awakening of a sleeping person can be reduced, and the comfort of awakening of a sleeping person can be improved.

    In addition, at the alarm sound stop time (Ts) of the alarm unit (30), the illuminance of the illumination unit (20) is higher than the low illuminance (L2) of the alarm sound occurrence time (Ta). As a result, after the sleeper awakens, the sleeper can be more comfortable without waking up the sleeper. Thereby, it is possible to prevent the sleeping person from sleeping twice after getting up.

    Furthermore, because the light emitting part (21) of the illuminating part (20) generates cold-colored or white light, the sleeper is in a lean state before the alarm sound generation time (Ta), etc. Even if the amount of light supplied to the sleeping person is extremely small, the awakening state of the sleeping person can be slightly reduced. Thereby, it is possible to further reduce discomfort when the sleeping person opens his eyes due to the generation of an alarm sound. In addition, the effect of preventing double sleep by lighting the illumination unit (20) after the alarm sound stop time (Ts) can be more reliably exhibited.

-Modification 1 of Embodiment 1-
In the first embodiment, the illuminance of the illumination unit (20) is a predetermined low illuminance (L2) lower than the predetermined illuminance (L1) from the time (Tb) immediately before the alarm sound generation time (Ta). Instead of doing so, as shown in FIG. 6, lighting of the illumination unit (20) is stopped at a time (Tb) immediately before the alarm sound generation time (Ta). That is, in this embodiment, lighting of the illumination unit (20) is stopped at the alarm sound occurrence time (Ta).

    Specifically, in the present embodiment, a lighting stop signal is output from the second control unit (42) to the first control unit (41) instead of the illuminance reduction signal of the first embodiment. Thereby, as shown in FIG. 6, lighting of the illumination part (20) stops from the time (Tb) immediately before the alarm sound generation time (Ta), and the illuminance of the illumination part (20) is from the predetermined illuminance (L1). Low 0 (ls).

    In this embodiment, since the illumination means (20) is stopped at the alarm sound occurrence time (Ta), the illuminance of the illumination unit (20) can be made lower than the predetermined illuminance (L1) with easy control. it can.

    Other configurations, operations, and effects are the same as those of the first embodiment.

<< Reference Example 1 >>
In the first reference example , the alarm sound stop time is changed from the first embodiment to a high illuminance (L3) higher than the low illuminance (L2) of the alarm sound occurrence time (Ta) at the alarm sound stop time (Ts). After (Ts), the low illuminance (L2) is maintained.

Specifically, as shown in FIG. 7, when the stop button (33) of the alarm unit (30) is pressed, after the alarm sound stop time (Ts), automatically or manually by a sleeping person or the like, 20) is turned off. That is, in the first reference example , the first control unit (41) is not controlled by the third control unit (43).

In addition, even if the modification 1 of the said Embodiment 1 and this reference example 1 are combined, and lighting after the time (Tb) immediately before alarm sound generation time (Ta), lighting of a lighting part (20) may be stopped. Good.

In the first reference example , since the control for increasing the lighting of the illumination unit (20) is not performed after the alarm sound stop time (Ts), the control is easier than in the first embodiment. Some sleepers may open the hood (4) of the bed (1) immediately after the alarm sound stop time (Ts) and exit the sleeping space (8). In such a case, the alarm sound stop time (Ts) Even if the illuminance of the lighting unit (20) is increased after that, it does not show the effect of preventing sleepiness after waking up. Whether to perform control by the third control unit (43) depending on a person who sleeps well (sleeping person who sleeps well) and a bedtime person who cannot leave the sleeping space (8) (sleeping person who sleeps poorly). May be.

    Other configurations, operations, and effects are the same as those of the first embodiment.

<< Reference Example 2 >>

It is comprised by the 2nd control means which controls a part (41).

-Driving action-
The operation of the alarm device (10) will be described with reference to FIGS.

    First, before the bedtime of a sleeping person, the time setting unit (51) sets a scheduled wake-up time (Ta) (for example, 7 o'clock).

    When a predetermined time (T1) (for example, 6:30) before the alarm sound generation time (Ta), which is the scheduled wake-up time (Ta), after the sleep start of the sleeper, the time setting unit (51) is predetermined. A notification signal at time (T1) is output, and the notification signal at time (T1) is input to the first control unit (41) of the illumination control unit (40). Accordingly, the first control unit (41) applies a voltage to the first light source unit (71) of the illumination unit (20) from the predetermined time (T1) to start lighting, and puts the sleeping person into the awake state. Induce.

    When the time (Tb) immediately before the alarm sound generation time (Ta) that is the scheduled wake-up time (Ta) (for example, 6:59 one minute before), the time setting unit (51) The notification signal at (Tb) is output, and the notification signal at the time (Tb) is input to the first control unit (41). Accordingly, the first control unit (41) stops the lighting of the first light source unit (71) and starts the lighting of the second light source unit (72) to turn on the lighting unit (20). Is switched.

    When the scheduled wake-up time (Ta) is reached, the time setting unit (52) causes the sound source control unit (32) of the alarm unit (30) to generate an alarm sound generation time (Ta) that is the scheduled wake-up time (Ta). The notification signal is output. As a result, the sound source unit (31) generates an alarm sound, and the bedtime is notified to the sleeping person. At this time, in the illumination unit (20), since the second light source unit (72) is lit, the sleeper is in a lean state until the alarm sound generation time (Ta), and the illumination unit (20) Even if the first light source part (71) is not sufficiently guided to the awake state, the light from the illumination part (20) does not feel dazzling when the sleeper awakens and opens his eyes. Will gradually feel stronger.

    When the stop button (33) is pressed due to the awakening of the sleeper, the sound source unit (31) stops the generation of the alarm sound, while the second control unit (43) sets the alarm sound stop time (Ts). A notification signal is output. Accordingly, the second control unit (43) outputs a lighting switching signal of the light source unit (71, 72) to the first control unit (41), and the first control unit (41) 71) is turned on while the second light source unit (72) is stopped.

In this reference example 2 , the applied voltage when turning on each light source unit (71, 72) is constant, but, as in the first embodiment, the first light source unit (71) is started from a predetermined time (T1). By gradually increasing the applied voltage, the sleeper may be able to reduce discomfort caused by a sudden light stimulus by the illumination unit (20). In addition, when the second light source unit (72) is lit, the applied voltage may be lower than when the first light source unit (71) is lit. Further, the second light source unit (72) may remain turned on after the alarm sound stop time (Ts).

-Effect of Reference Example 2-
In this reference example 2 , from the predetermined time (T1) before the alarm sound generation time (Ta) of the alarm unit (30), the first light source unit (71) of the illumination unit (20) is turned on to display a cold or white color. On the other hand, at the alarm sound generation time (Ta), the second light source part (72) of the illumination part (20) is turned on to generate warm color light. While the sleeper can be induced to awake before the time of occurrence (Ta), the sleeper is not sufficiently induced to awake due to being in a lean state before the alarm sound generation time (Ta) Even when the eye is opened due to the generation of an alarm sound, it is possible to reduce the dazzling light supplied from the illumination means (20) and to gradually feel the light after opening the eye to ensure that it is awakened. be able to. As a result, it is possible to improve the awakening comfort of the sleeping person.

    In addition, since the first light source unit (71) is turned on at the alarm sound stop time (Ts), it is possible to prevent sleepiness from being induced in the sleeper after the stop time (Ts). The awakening feeling of the person can be made more comfortable. Thereby, it is possible to prevent the sleeping person from sleeping twice after getting up.

    Other configurations, operations, and effects are the same as those of the first embodiment.
