  Conventionally, a storage unit that stores awakening operation time and awakening time, a discharge lamp that is a light source, and a light output from the discharge lamp that gradually increases from the stored waking operation start time to the awakening time. Japanese Patent Laid-Open No. 07-318670 (Patent Document 1) is known as an awakening device provided with a dimming control unit that performs dimming control.

The purpose of this is to synchronize the circadian rhythm, which is one of the biological rhythms, with the life cycle to make the sleeper's awakening more comfortable. At the start of the awakening operation, the illuminance by the incandescent light source is 0 lux. The present invention relates to a technique for gradually increasing the illuminance from 200 to 1000 lux to medium illuminance and then rapidly changing the illuminance to high illuminance of 1000 lux or higher.
JP 07-318670 A

  However, the wake-up device whose illuminance on the sleeping subject's face is 0 lux at the start of the wake-up operation can provide the awakening environment close to natural dawn to the sleeping person, but dimming from 0 lux is possible As a wake-up device, there is a ceiling light that combines an incandescent lamp in charge of illuminance from 0 lux to a dozen lux and a discharge lamp in charge of higher illuminance, Standlights that are in the vicinity of a sleeping person's face are commonly used, with the range being incandescent.

  Therefore, in the former, the light source cannot be configured with only a general-purpose discharge lamp, and there is a possibility that the cost and size of the entire apparatus may be increased. Moreover, in the latter, it cannot respond to the position shift by a sleeping person's turnover etc., and awakening of a sleeping person may not be made comfortable.

  Also, in the above conventional example, if the light source is configured with only a general-purpose discharge lamp, the output of the light source at the start of the awakening operation is substantially zero, that is, the lamp current of the discharge lamp at the start of the awakening operation is less than 5 milliamperes. In such a wake-up device, there is a possibility that the lighting circuit becomes complicated for stable lighting or a pulse current needs to be superimposed, resulting in an increase in cost.

  The pulse current is superimposed here because it is difficult to maintain a stable arc discharge when lighting at a lamp current of less than 5 milliamps, and there is a risk of transition to lamp extinction (glow discharge). This is to avoid arc and maintain arc discharge.

  In particular, in the case where the pulse current is superimposed, there is a possibility that the consumption of the lamp electrode is likely to proceed, and furthermore, a comfortable awakening of the sleeper may be hindered by the noise generated.

  The present invention has been made in view of the above-described background art, and the problem is that the storage unit stores the time of awakening operation and the time of awakening, the discharge lamp as a light source, and the stored time of the awakening operation. And a dimming control unit that performs dimming control so that the light output from the discharge lamp increases step by step toward awakening, and a light source can be configured with only a general-purpose discharge lamp. An object of the present invention is to provide an awakening device that can suppress an increase in cost and size of the entire device.

In order to solve the above-mentioned problem, the invention according to claim 1 of the present application is directed to a storage unit that stores awakening operation start time and awakening time, and a discharge lamp that is disposed at a predetermined distance from a sleeping person's face. And a dimming control unit that performs dimming control so that the light output from the discharge lamp increases stepwise from the start of the stored waking operation to the time of waking. The lamp current of the discharge lamp at the start of the awakening operation is 5 mA or more, and the illuminance on the face of the sleeper who is the awakening target at the start of the release awakening operation is greater than 0 lux and less than 23 lux at the start of the awakening operation In addition, there is a changing point where the increase rate of the light output from the discharge lamp changes between the start of the awakening operation and the awakening time, and the illuminance on the face of the sleeper who is the awakening target is 40 at the changing point. And a box below, is awake and wherein the at waking is 100 lux or more.

Further, the invention according to claim 2 of the present application is the wake-up device according to claim 1, wherein the flashing of the discharge lamp at the start of the wake-up operation is 20 milliseconds or less.

  Here, the flashing of the discharge lamp refers to the time from the start of lighting of the discharge lamp to the time when the flash generated at the start of lighting of the discharge lamp is extinguished and stable lighting is achieved at a set dimming level. The flash occurs due to various causes, but is caused by a voltage applied to the preheating capacitor before lighting to preheat the discharge lamp.

  According to the invention described in claim 1 of the present application, since it is greater than 0 lux at the start of the awakening operation, it is possible to configure a light source with only a general-purpose discharge lamp, and it is possible to suppress an increase in cost and an increase in size. Moreover, since it is 23 lux or less, it does not wake up at the time of awakening operation start.

Moreover , since the change point and the illuminance at the time of awakening are set lower than in the case of an incandescent lamp (250 to 1000 lux or the like), no uncomfortable feeling is felt at the time of awakening.

Furthermore , since the lamp current of the discharge lamp at the start of the awakening operation is 5 milliamperes or more, it is possible to avoid making the lighting circuit complicated for stable lighting and superimposing the pulse current, Cost increase can be suppressed.

  In particular, since it is possible to avoid superimposing a pulse current, the consumption of the lamp electrode is suppressed, and the comfortable awakening of the sleeper is not hindered by the generated noise.

According to the invention described in claim 2 of the present application, since the flash is not longer than 20 milliseconds, the user does not wake up at the start of the awakening operation.

The illuminance on the face of the sleeping person who is the awakening target is greater than 0 lux and equal to or less than 23 lux at the start of the awakening action.

  Further, there is a changing point 5 where the increase rate of the light output from the discharge lamp 4 changes from the start of the awakening operation to the awakening time. Less than lux, and more than 100 lux at awakening.

  Further, the lamp current of the discharge lamp 4 at the start of the awakening operation is 5 milliamperes or more.

  Furthermore, the flashing of the discharge lamp 4 at the start of the awakening operation is 20 milliseconds or less.

  Hereinafter, the awakening device 1 according to the present embodiment will be described in more detail.

  First, the storage unit 2 includes a box-shaped outer shell, and includes an input terminal 21 that is exposed to the room from a part of the outer shell and a storage circuit 22 that is housed inside the outer shell. Is done.

  The input terminal 21 is of a touch panel type, and can input a wake-up time that is awakening in accordance with an instruction of a displayed menu. Here, a function other than the function of inputting the wake-up time at the time of awakening, for example, an operation function for turning on / off the discharge lamp 4 may be used.

  The memory circuit 22 is a general-purpose memory and stores the wake-up time that is the input awakening time. The wake-up time that is the awakening time stored in the storage circuit 22 is digitally encoded and transmitted to the dimming signal generation circuit 32 of the dimming control unit 3 to be described later via the communication line.

  Next, the dimming control unit 3 has a box-shaped outline, and includes a timer circuit 31, a dimming signal generation circuit 32, and an oscillation circuit 33 housed inside the outline. .

  The timer circuit 31 measures the current time. The posted current time is digitally encoded and transmitted to a dimming signal generation circuit 32 described later via a communication line.

  The dimming signal generation circuit 32 includes a microcomputer, and dimming control is performed on the discharge lamp 4 in accordance with the wake-up time and the current time that have been transmitted and the stored dimming control program (details will be described later). The dimming signal is generated.

  The dimming signal is known as a so-called PWM method in which the discharge lamp 4 is dimmed and controlled with a duty ratio of the output voltage which is a rectangular wave, and the duty ratio is 0 to 5% as shown in FIG. 100% lighting, 85% to 100%, 10% lighting, and 5 to 85% change in proportion from 100% lighting to 10% lighting.

  The oscillation circuit 32 is a half-bridge inverter, and receives DC power from a power supply unit (not shown) and supplies high-frequency power corresponding to the dimming signal to the discharge lamp 4.

  Here, as described in JP-A-2001-284091, a coupling capacitor (not shown) connected between a ballast choke (not shown) for limiting the lamp current of the discharge lamp 4 and a preheating electrode (not shown). A voltage detection circuit (not shown) for detecting the voltage across the lamp, a dimming start control circuit (not shown) for controlling the dimming start of the discharge lamp 4, and the current of the discharge lamp 4 are detected so that they are constant. In addition, the oscillation circuit 32 is provided with a feedback circuit (not shown) that performs so-called feedback control, and is dimmed by a difference between a preheating period of the discharge lamp 4 and a detection signal output from the voltage detection circuit after the start of discharge. The start control circuit masks the feedback circuit from not operating during the preheating period, while the discharge lamp 4 starts massing. By releasing to dimming it is possible to be started, and suppresses the flash below 20 milliseconds.

  Next, the discharge lamp 4 is a general-purpose fluorescent lamp. In this embodiment, an FHD85EL 100-hour aging lamp (manufactured by Matsushita Electric Industrial Co., Ltd.) was used. In addition to fluorescent lamps, general-purpose discharge lamps such as high-intensity discharge lamps and electrodeless discharge lamps can be used.

  As shown in FIG. 3, the awakening device 1 of the present embodiment is installed in a bedroom provided with a bed 6 on which a sleeper sleeps, a storage unit 2 on a wall surface, a dimming control unit 3 on a ceiling, a discharge lamp 4 are each installed in the approximate center of a ceiling surface in the state installed in the lighting fixture. The lighting fixture can be provided with a general-purpose reflector or shade.

  Here, the bedroom has a square shape with a floor area of 2.7 m × 3.6 m, and the bed 6 is installed at the corner so that the long side is along the length of the bedroom. The ceiling height is 2.4 m, the height of the bed 6 is 0.4 m, and the distance between the discharge lamp 4 and the bed is approximately 2 m.

  Subsequently, the operation of the awakening device 1 of the present embodiment will be described with reference to FIG. The awakening device 1 awakens a sleeping person by dimming the discharge lamp 4 according to a dimming control program stored in the dimming control unit 3.

  Here, the dimming control program is set so that the wake-up operation starts 30 minutes before the wake-up time, which is the time of awakening. However, the discharge lamp 4 is dimmed so that it is greater than 0 lux and less than or equal to 23 lux at the start of the awakening operation.

  Thereafter, the light output at the start of the awakening operation is maintained until 10 minutes before the wake-up time, which is awakening, or the light output is gradually increased, and the sleeper who is a wake-up object 10 minutes before the wake-up time, which is the awakening time. The discharge lamp 4 is dimmed and lit so that the illuminance on the face becomes 40 lux or less at the change point 5. The increase rate of the light output from the discharge lamp 4 changes before and after 10 minutes before the wake-up time, which is awakening, and this point is indicated as a change point 5.

  Here, as long as the light output from the discharge lamp 4 increases stepwise from the start of the awakening operation toward the awakening, the light output may be constant in a part of the section.

  For example, as described above, the illuminance between the start of the awakening operation and the change point may be constant.

  The stepwise increase does not only mean a stepwise increase, but the light output from the discharge lamp 4 may gradually increase from the start of the wake-up operation to the wake-up time.

  Further, the light output is increased until the wake-up time at the time of awakening, and the discharge lamp 4 is turned on so that the illuminance on the face of the sleeper who is the wake-up target is 100 lux or more at the wake-up time at the time of awakening.

This is representative data of the evaluation of the influence on the sleeper, the evaluation of the influence on the stable lighting of the discharge lamp by the set lamp current at the start of the awakening operation, and the evaluation of the influence on the sleeper by the flashing at the start of the awakening operation.

  Here, the evaluation of the influence on the sleeper by the illuminance at the start of the awakening operation is performed by lighting the discharge lamp 4 at a dimming level of a predetermined condition from 30 minutes before the wake-up setting time, and how many minutes before the wake-up setting time in each condition I was asked to report whether I got up.

  In addition, the illuminance was measured with an illuminometer in which the face illuminance was set at the center position between both eyes of the sleeping person and the light receiving part was placed parallel to the face. The measurement was performed with the light receiving unit facing upward when the face was up when it was up, and facing right when it was facing right.

  In addition, the evaluation of the influence of the change point 5 or the illuminance at the time of waking on the sleepiness of the sleeper is performed by operating the wake-up device 1 under the conditions shown in Table 1 from 30 minutes before the set-up time to the set-up time. I was asked to self-report my mood when I woke up after the set-up time.

  Further, in the evaluation of the influence of the set lamp current at the start of the awakening operation on the stable lighting of the discharge lamp 4, it was determined whether or not the superposition of the pulse current was necessary for the stable lighting.

  Here, the lamp current was measured by a test method of electrical characteristics according to JIS C 7618-2 Annex B. As described above, the discharge lamp 4 was an FHD85EL 100-hour aging lamp (manufactured by Matsushita Electric Industrial Co., Ltd.).

  In addition, the evaluation of the influence on the sleeper by the flash at the start of the wake-up operation is performed by operating the wake-up device 1 under the conditions shown in Table 1 from 30 minutes before the wake-up set time to the wake-up set time. I was asked to report how many minutes ago I got up and how I felt when I woke up.

  Here, the flash was measured by a test method of electrical characteristics according to JIS C 7618-2 Annex B. As described above, the discharge lamp 4 was an FHD85EL 100-hour aging lamp (manufactured by Matsushita Electric Industrial Co., Ltd.).

  As measurement conditions, there was no stabilization time (to observe the flash immediately after the lamp was turned on), and the ambient temperature was 25 ± 1 ° C. and no wind.

  As a measuring instrument, a digital oscilloscope model number LC334AL (manufactured by LeCroy), a light receiver (+ amplifier) model number 70311 (+70703), and (manufactured by Thermo Oriel INSTRUMENTS) are used. 4 was converted into a voltage, and the waveform was observed with this oscilloscope.

  The observed light output exceeds the dimming level set immediately after the lamp is turned on and gradually decreases to the set dimming level, but reaches the set dimming level immediately after the lamp is turned on. The period until is defined as flush.

  As shown above, as is clear from the results of Examples 1 to 10 and Comparative Examples 1 and 5, according to the present embodiment, the general discharge lamp 4 is larger than 0 lux at the start of the awakening operation. The light source can be configured only by this, and the cost increase and the increase in size can be suppressed. Moreover, since it is 23 lux or less, it does not wake up at the time of awakening operation start.

  Further, as apparent from the results of Examples 1 to 10 and Comparative Examples 5 to 8 and the results of Examples 1 to 10 and Comparative Examples 1 to 4, the change point 5 and the illuminance at the time of awakening are incandescent. Since it was set lower than the case (250-1000 lux, etc.), there is no discomfort at awakening.

  Further, as is apparent from the results of Examples 1 to 10 and Comparative Examples 1 and 5, the lamp current of the discharge lamp at the start of the awakening operation is 5 milliamperes or more. Can be prevented from being complicated and the pulse current can be superimposed, and the cost can be suppressed.

  In particular, since it is possible to avoid superimposing a pulse current, the consumption of the lamp electrode is suppressed, and the comfortable awakening of the sleeper is not hindered by the generated noise.

  Further, as is apparent from the results of Examples 1 to 10 and Comparative Examples 9 to 10, the flash is not longer than 20 milliseconds, so that the user does not wake up at the start of the awakening operation.

  In the present embodiment, the storage unit 2 and the dimming control unit 3 are separated from each other, but they may be integrated.

  In the storage unit 2, the input terminal 21 and the storage circuit 22 may be separated from each other, and the storage circuit 22 may be integrated with the dimming control unit 3.
