(First embodiment)
As shown in FIGS. 1 to 3, the light irradiation device 1 according to the first embodiment of the present invention includes a goggle unit 2, a headphone unit 3 that is an example of a holding unit, and a goggle unit 2 and a headphone unit 3. Optical fiber cables 4 and 4 having an optical path between them. The goggle unit 2 includes irradiation units 5 and 5 that receive light emitted from one end of the optical fiber cables 4 and 4 and irradiate the subject's eyes with light while the subject M wears the goggle unit 2.

  By configuring the light irradiation device 1 in this way, the light irradiation device 1 is lightweight and small, and further, even during the execution of the optical health maintenance method, the visual field of the subject M is not hindered. Can move while the light irradiation device 1 is attached even during the implementation of the optical health maintenance method. Moreover, the goggles part 2 has the irradiation part 5 above the test subject's M eyelid, as shown in FIG. According to this, the optical health maintenance method can be implemented without the light irradiation device 1 preventing the movement of the subject M and without the irradiation unit 5 blocking the field of view of the subject M. Thereby, the freedom degree of the movement of the test subject M during implementation of the optical health maintenance method can be secured, and the stress of the test subject M can be reduced. In all matters described below, it is possible to reduce the stress of the subject M by ensuring the freedom of movement of the subject M during the implementation of the optical health maintenance method. The effect will be described.

  Further, as shown in FIG. 3, the headphone unit 3 includes light sources 6 and 6 and LEDs 7 and 7 which are LEDs (Light Emitting Diodes) that allow light to enter the other ends of the optical fiber cables 4 and 4. According to this, since the irradiation part 5 does not have the light source 6, the irradiation part 5 can be reduced in weight and size. Therefore, since the goggle part 2 having the irradiation part 5 can be reduced in weight, the subject M can obtain a comfortable feeling of wearing the goggle part 2.

  Furthermore, the headphone part 2 has the ventilation parts 8 and 8 which blow with respect to the test subject's M cheek in the state with which the test subject M was mounted | worn. Moreover, the ventilation parts 8 and 8 have the motors 9 and 9, the fans 10 and 10 rotated by the motors 9 and 9, and the heaters 11 and 11 which warm the air to blow. Further, the remote controller 12 has a switch (not shown) for switching the heaters 11, 11 to an operating state (ON state) or a non-operating state (OFF state). Further, the headphone unit 3 is provided with an air blowing hole 13 so that the wind generated by the fans 10 and 10 goes out.

  According to this, the subject M can hear his / her favorite music and sound effects (such as murmurs and wild birds) from the speaker 7 during the implementation of the optical health maintenance method. You can feel irritation by receiving cold or warm air on your cheeks. For example, in an environment where the temperature is high, the cold air is blown to the cheek of the subject M by turning off the heaters 11 and 11. If the temperature is low, warm air is blown to the cheek of the subject M by putting the heaters 11 and 11 in the operating state. According to this, the subject M can be distracted by the music and sound effect that the subject M likes during the light treatment, and can feel the stimulation of cold air or warm air on the cheek. You can avoid getting bored.

  Further, the headphone unit 3 may be provided with a scent generating means soaked with a specific scent component inside the air blowing hole 13 or the like. For example, as shown in FIG. 3, felt F or the like impregnated with a fragrance as a means for generating a scent such as a scent of an herb, cinnamon, or a fragrant tree that has an effect of relaxing the mental state of the subject M It may be provided on the inner side (between the air blowing hole 13 and the heater 11) and delivered to the nose of the subject M on the airflow generated by the air blowing unit 8. According to this, the effectiveness of the optical health maintenance method for the subject M can be enhanced by the scent in addition to the light and the wind. In addition, illustration of the felt F in FIG.3, FIG.8, FIG.9 is for making an explanation easy to understand, and does not limit felt F (namely, fragrance generating means) as an essential component.

  The battery 14 of the light irradiation device 1 is built in the remote control operation unit 12. According to this, it is possible to avoid an increase in the weight of the goggle unit 2 or the headphone unit 3 due to the weight of the battery 14. According to this, the subject M can obtain a comfortable feeling of wearing the goggle part 2 and the headphone part 3. Note that the connection between the battery 14 and the light sources 6 and 6 as the power supply destination, the speakers 7 and 7, the motors 9 and 9 of the blower units 8 and 8, and the heaters 11 and 11 is not shown.

  As shown in FIG. 3, the headphone unit 3 includes a control unit 15. Connected to the control unit 15 are light sources 6 and 6, speakers 7 and 7, motors 9 and 9 for the air blowing units 8 and 8, heaters 11 and 11, and a remote control operation unit 12. The control unit 15 is an example of a computer and includes a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), a microprocessor (microcomputer), a DSP (Digital Signal Processor), and the like. It has a memory, an I / O (Input / Output) port, and the like. The program executed by the control unit 15 can be installed in advance in the control unit 15 that is a computer by storing the program in a nonvolatile memory inside the control unit 15 in advance.

  When the control unit 15 executes the program, the function of the control means is realized, and the light sources 6 and 6 connected to the control unit 15, the speakers 7 and 7, the motors 9 and 9 of the blower units 8 and 8, and the heaters 11 and 11 Is controlled by the control unit 15. Further, the control unit 15 performs various controls based on instructions from the remote control operation unit 12. For example, the control unit 15 enters the operating state or the non-operating state according to an instruction from the remote control operation unit 12, and accordingly starts or ends the irradiation of light from the light source 6. Alternatively, the control unit 15 sends music and sound effects stored in advance in a memory (not shown) to the speakers 7 and 7 according to an instruction from the remote control operation unit 12. Or the control part 15 makes the ventilation part 8 and the heater 13 into an operation state or a non-operation state by the instruction | indication from the remote control operation part 12. FIG.

  Next, the illuminance of the light source 6 adjusted by the control unit 15 will be described with reference to FIG. As described above, the light irradiation device 1 irradiates a subject with light in order to improve biological rhythm (internal clock) abnormality such as seasonal emotional disorder, intrinsic depression, sleep / wake rhythm disorder, or jet lag. Is. Light irradiation for the light health maintenance method is started from the “0” point on the left side of FIG. 4, and the light irradiation ends at the “0” point on the right side of FIG. 4 (that is, the point reaching the horizontal axis).

  In the example of FIG. 4, the control unit 15 increases the illuminance gradually until a predetermined time t <b> 1 elapses from the start of irradiation of the irradiation units 5 and 5, and the predetermined irradiation end scheduled time set on the basis of the irradiation start time. Control is performed so that the illuminance gradually decreases before time t2, and the predetermined time t2 is set shorter than the predetermined time t1. Further, the control unit 15 determines that the predetermined time t1 has elapsed after the illuminance increase rate α% and the predetermined time t3 have elapsed from the start of irradiation of the irradiation units 5 and 5 until the predetermined time t3 shorter than the predetermined time t1 has elapsed. The increase rate of illuminance until β is controlled so that the former (α%) is smaller than the latter (β%).

  According to this, since the eye of the subject M is not yet used to the brightness at the start of irradiation, the illuminance increase rate (α%) is moderate, and then the illuminance increase rate (β%) is slightly larger. it can. Thus, at the start of irradiation, the illuminance change gentle to the eyes of the subject M can be made, but the increase rate of illuminance can be slightly increased from time t3 in order to avoid prolonging the time of the optical health maintenance method. Further, by gradually decreasing the illuminance from the time t2 toward the irradiation end scheduled time, the eye of the subject M can be gradually accustomed to normal brightness.

  Further, as shown in FIG. 5, the control unit 15 emits yellow light until a predetermined light amount is reached (for example, until time t4) among the light amounts irradiated from the start of irradiation of the irradiation unit 5 to the end of irradiation. Thereafter, white light is irradiated, and control is performed so that yellow light is irradiated again from a predetermined time before the irradiation end scheduled time (for example, time t5). According to this, the subject M becomes a pseudo one by changing the color of the yellow light and the irradiation light which are included in the sunset again from the yellow light included in the sunrise to the white light which is included in the daytime. You can experience the change of sunlight in the day. Thus, the subject M can carry out the light health maintenance method without learning an unnatural feeling due to the change in the light color in accordance with the change in the natural light color. In order to change the color of light emitted from the irradiation unit 5, for example, the light source 6 is a two-color LED and the control unit 15 is controlled to select one of the two-color emission colors. do it. Alternatively, the light source 6 may be an RGB (red, green, and blue) LED that emits light of three colors, and the control unit 15 may control the light emission of the three colors to obtain a desired light emission color.

(Second embodiment)
A light irradiation apparatus 1A according to a second embodiment of the present invention will be described with reference to FIG. The light irradiation apparatus 1A is partially different from the light irradiation apparatus 1. Hereinafter, members different from the light irradiation device 1 of the light irradiation device 1A will be mainly described, and descriptions of common members will be omitted or simplified.

  The headphone unit 3A of the light irradiation device 1A includes mirrors 16A and 16A that reflect and enter light emitted from the light sources 6A and 6A at the other ends of the optical fiber cables 4 and 4, respectively. At this time, the other ends of the optical fiber cables 4 and 4 and the light sources 6A and 6A are both arranged substantially coaxially facing the direction of the mirrors 16A and 16A. According to this, in the light irradiation apparatus 1, the other end of the optical fiber cable 4 and the light source 6 that are arranged to face each other are arranged. In the light irradiation apparatus 1A, the other end of the optical fiber cable 4 and the light source 6A are arranged. They can be arranged in a vertical row or a horizontal row and arranged toward the mirror 16A. Here, since the thickness of the mirror 16A can be very thin, the other end of the optical fiber cable 4 and the light source are arranged by aligning the other end of the optical fiber cable 4 and the light source 6A in a vertical line or a horizontal line. Compared to the light irradiation device 1 in which the light sources 6 are disposed so as to face each other, the space required for the light source 6A can be reduced. Accordingly, the headphone unit 3A of the light irradiation device 1A can be downsized as compared with the headphone unit 3 of the light irradiation device 1.

(Third embodiment)
A light irradiation apparatus 1B according to a third embodiment of the present invention will be described with reference to FIG. The light irradiation device 1B is partially different from the light irradiation device 1A. Hereinafter, members different from the light irradiation device 1A of the light irradiation device 1B will be mainly described, and descriptions of common members will be omitted or simplified.

  In the light irradiation device 1B, two light sources 6B and 6C and two mirrors 16B and 16C are arranged on the other end of one optical fiber cable 4. In FIG. 7, light sources 6C and 6C and mirrors 16C and 16C function in the same manner as the light irradiation apparatus 1A. On the other hand, in FIG. 7, the optical path formed by reflecting the light emitted from the light sources 6B and 6B to the mirrors 16B and 16B is arranged so as to pass almost the same optical path as the light sources 6C and 6C. Thereby, the light emitted from the two light sources 6B and 6C is incident on the other end of the optical fiber cable 4 in a superimposed manner. According to this, the light quantity emitted from one end of the optical fiber cable 4 and incident on the irradiation unit 5 can be increased as compared with the light irradiation apparatus 1A.

(Fourth embodiment)
A light irradiation apparatus 1C according to a fourth embodiment of the present invention will be described with reference to FIG. The light irradiation device 1 </ b> C is partially different from the light irradiation device 1. Hereinafter, members different from the light irradiation device 1 of the light irradiation device 1C will be mainly described, and descriptions of common members will be omitted or simplified.

  As illustrated in FIG. 8, the light irradiation device 1 </ b> C includes a temperature measuring unit 17 in the headphone unit 3 </ b> C. The temperature measuring unit 17 is a sensor that measures the body temperature of the subject. The temperature measuring unit 17 is preferably attached to, for example, a portion of the headphone unit 3C that comes into contact with the skin of the subject, and measures the body temperature of the subject. For example, in order to stably measure the body temperature of the subject, the temperature measuring unit 17 is preferably inserted into the ear hole of the subject. At this time, in order not to make it difficult for the subject to hear the sound of the speaker 7 due to the temperature measuring unit 17 being inserted into the ear hole, the ear hole is completely blocked by making the diameter of the temperature measuring unit 17 smaller than the diameter of the ear hole. It is preferable not to have any.

It is generally known that a subject tends to increase in body temperature as the degree of arousal is higher. Therefore, the control unit 15C of the light irradiation device 1C can perform control so as to change the scheduled irradiation end time of light based on the measurement result of the temperature measurement unit 17. For example, the control unit 15C of the light irradiating device 1C, when an increase in the body temperature of the subject is confirmed even before the scheduled irradiation end time of light based on the measurement result of the temperature measuring unit 17 is confirmed. It can be controlled to end the light irradiation. According to this, it is possible to eliminate the subject from being subjected to the optical health maintenance method for a longer time than necessary. On the contrary, the control unit 15C of the light irradiation device 1C irradiates the light when the increase in the body temperature of the subject is not confirmed even after the scheduled irradiation end time of light based on the measurement result of the temperature measurement unit 17. Can be controlled to extend. According to this, an effective optical health maintenance method can be applied to the subject.

(Fifth embodiment)
A light irradiation apparatus 1D according to a fifth embodiment of the present invention will be described with reference to FIG. The light irradiation device 1D is partially different from the light irradiation device 1. Hereinafter, members different from the light irradiation device 1 of the light irradiation device 1D will be mainly described, and descriptions of common members will be omitted or simplified.

  As illustrated in FIG. 9, the light irradiation device 1 </ b> D includes blink sensors 18 and 18 that detect the open / closed state of the eyes in the goggles 2 </ b> D. That is, the blink sensors 18 and 18 are sensors that detect whether or not the subject's eyelid is closed. The detection results of the blink sensors 18 and 18 are taken into the control unit 15D.

  When receiving the detection results of the blink sensors 18 and 18, the control unit 15 </ b> D integrates the time during which the subject's eyelids are closed from the start of light irradiation. The control unit 15D extends the irradiation end scheduled time of the integrated time spectroscopy in which the subject's eyelid is closed. According to this, the execution time of the optical health maintenance method can be set in real time when the subject is actually receiving light irradiation, so that the optical health maintenance method can be effectively implemented.

  When the subject falls asleep during the execution of the optical health maintenance method, the blink sensors 18 and 18 detect the closed eye state for a long time (for example, several minutes) longer than a predetermined time. In such a case, the control unit 15D awakens the subject by issuing an alarm. According to this, a test subject can be made to receive the optical health maintenance method correctly. Here, “to issue an alarm” may be such that the headphone unit 3 gives a stimulus to the subject M with a loud sound or a strong wind. Moreover, when the felt F which is a fragrance generating means is provided inside the air blowing hole 13, the subject M may be stimulated by the scent.

(Sixth embodiment)
A light irradiation apparatus 1E (not shown) according to a sixth embodiment of the present invention will be described with reference to FIG. The light irradiation device 1E is partially different from the light irradiation device 1D.

Further, the irradiation units 5 and 5 shown in FIG. 9 are replaced with irradiation units 5E and 5E (not shown) having variable irradiation angles. The control unit 15D is also replaced with a control unit 15E (not shown) having a different control content. In order to change the irradiation angle of the irradiating units 5E and 5E, for example, a plurality of optical fiber cables 4 and 4 are arranged, and a plurality of optical fiber cables 4 and 4 are provided in the headphone unit 3E (not shown). A plurality of light sources 6 and 6 corresponding to each of the light sources 6 and 6 are arranged, and the irradiation sections 5E and 5E are provided with a plurality of irradiation ends that are joined to one end of each of the plurality of optical fiber cables 4 and 4 and have different irradiation angles. Just do it. The control unit 15E (not shown) can change the irradiation angle of the irradiation units 5E and 5E by controlling which of the light sources 6 and 6 is turned on.

  Accordingly, the control unit 15E changes the irradiation angle of the irradiation units 5E and 5E to an angle at which light is easily irradiated to the eyeball of the subject based on the detection results of the eyeball position detection sensors 18E and 18E. According to this, even if the position of the eyeball of the subject moves, the eyeball of the subject can be efficiently irradiated with light, so that the subject can be subjected to the optical health maintenance method correctly and efficiently.
