Description

  The present invention irradiates light to the eye and the vicinity of the eye from a light source, so that the rhythm, brightness, time of the light to be irradiated, the frequency of the light to be irradiated, and the color and color of the human, The so-called “light therapy effect” (uses light therapy) that can adjust the rhythm of sleep and awakening, as well as mental stability and activation, seasonal physical condition adjustment, and fatigue recovery such as eye fatigue. The present invention relates to a wearable light irradiation apparatus capable of exhibiting light therapy (also called phototherapy or high illumination therapy).

  In recent years, many people feel sleepy during the day for various reasons. For example, for young people, the Internet has developed rapidly, resulting in lack of sleep, and late nights have caused the sleep hours to shift backwards. In addition, people who work in shifts and those who work late at night may become sleepy during work, causing mistakes and accidents. Furthermore, people who have returned from overseas travel must fight against jet lag.

  By the way, biological rhythms such as daily sleep and awakening play a very important role in human life, and when the biological rhythm collapses, various symptoms such as fatigue, reduced concentration, stress, indigestion, etc. Cause. For example, in regions with low sunshine hours, there are many people who do not feel good in the fall and winter when the daytime brightness tends to be insufficient, and in the morning when the weather is not good, they feel bad and unwell. is there.

  Such biological rhythm is deeply related to light, and light plays an important role in improving these symptoms. In particular, the biological clock, which is said to have a cycle of 25 hours a day, is set to 24 hours a day. The influence on the synchronization mechanism of the circadian clock is increasing. Therefore, for example, if you are indoors during the day or in the fall and winter, the daylight hours are short and you cannot take sunlight, so there is no distinction between day and night, the rhythm of your body is disturbed, and the above fatigue and concentration It causes various symptoms such as low blood pressure, stress and indigestion.

On the other hand, when the person is sleepy during the day and is not awake, the night may cause insomnia, and the vicious circle is repeated.
However, people who have sleepiness during the day and suffer from insomnia at night, or those who are not feeling well, can eliminate their sleepiness, eliminate insomnia, or improve their mood. To do this, light exercise or sufficient exposure to sunlight leads to a solution, but in recent years this has not been possible. Furthermore, in regions where there is little sunshine time, it is the actual situation that sunlight cannot be sufficiently taken.

  Also, for example, for those who have to perform shift work such as night shifts or quasi-night shifts such as nurses, it is necessary to wake up positively in order not to make work mistakes, but they will definitely wake up The fact is that there is no way.

  For this reason, so-called “high illumination light therapy (phototherapy)” is conventionally known as a treatment method for abnormal biological rhythm (internal clock), insomnia, arousal disorder, seasonal emotional disorder and the like.

  This high-illumination light therapy method is used for, for example, treatment of endogenous depression and senile mania, and also reduces fatigue due to night work, jet lag, and long hours under low-light illumination. It is also used to relieve stress.

  In such high illuminance light therapy, a high illuminance artificial light irradiation device with a color temperature close to that of sunlight is used, and light stimulation is required for a time period corresponding to abnormal sleep wake rhythm or awakening In this time zone, the irradiation is performed by irradiating light to the eye of the patient and the vicinity of the eye for the irradiation time according to the illuminance.

For this reason, various types of stationary light irradiation devices have been developed in order to implement high-intensity light therapy.
However, such stationary light-emitting devices for awakening require high illuminance at a certain distance, and are therefore often large-sized and are inconvenient to carry and carry. For example, they are used in a long airplane. If you need to awaken, or if you want to eliminate disturbance of biological rhythm, you can not use it anytime and anywhere, and you need to receive light while maintaining a specified distance to the irradiation device during treatment time Therefore, it is inconvenient because a free posture cannot be achieved.

Furthermore, since the irradiated light is also irradiated to the people in the vicinity, it may be annoying to the people around and may disturb the biological rhythm of the people around it.
For this reason, in Patent Document 1 (Japanese Patent Laid-Open No. 9-213101), a wearable light irradiation apparatus having a light irradiation device in the sun visor eaves portion is disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 11-188098). In Japanese Patent Application Laid-Open No. 2003-144482, a wearable light irradiation device having a headband type light irradiation device positioned in front of a human body face is disclosed as an eye mask type wearable light irradiation. Further, in Japanese Patent Application Laid-Open No. 2002-350790, a spectacle-type wearable light irradiation device has been proposed.
JP-A-9-213101 Japanese Patent Laid-Open No. 11-188098 JP 2003-144482 A JP 2002-350790 A

  However, the conventional sun visor type of Patent Document 1 and the headband type wearable light irradiation apparatus of Patent Document 2 are both heavy to wear on the head and obstruct the field of view in a wide range. Discomfort or pressure.

  In addition, the eye mask type of Patent Document 3 gives psychological anxiety to completely deprive the field of vision, cannot do other things such as reading during treatment, and also obstructs the field of vision if it is not a constant posture. Therefore, safety cannot be ensured.

On the other hand, the spectacle-type wearable light irradiation device disclosed in Patent Document 4 is not suitable for long-time use or regular use for a person unfamiliar with spectacles.
Furthermore, the conventional stationary light irradiation device is not configured to exhibit a so-called “color therapy effect” that relaxes the mood by changing the color of light.

  In view of such a current situation, the present invention is compact, lightweight, portable and convenient to carry, has no feeling of pressure even when worn for a long time, reduces physical and psychological discomfort, and is being treated. The ability to select the treatment posture and treatment location, such as being able to perform reading, etc., as well as freedom of movement and safety, as well as the appropriate illumination intensity, treatment time, etc. for treatment It aims at providing a light irradiation apparatus.
