And a sunlight transmitting member 52. Moreover, as a constituent material of the sunlight transmission part 52, various glass, various resin, etc. can be used, for example.

  The daylighting opening 50 is disposed at a position where it receives direct sunlight regardless of time and season in the roof 21 of the house 10, for example, at a position facing the south side. Is preferred.

  In the house 10, sunlight is collected into the cabin space 41 of the housing space 40 through the sunlight collection opening 50.

  The light guide 60 is arranged in a plurality of reflectors 61 to 73, that is, reflectors 61 and 62 disposed in the cabin space 41, reflectors 63 to 68 disposed in the inner wall space 45, and the underfloor space 42. The reflectors 69 to 71 are provided, and the reflectors 72 and 73 are disposed in the inner wall space 44.

  As shown in FIG. 2, the positions (arrangement) and inclination angles (postures) of the reflectors 61 to 73 are determined by the sunlight collected in the cabin space 41 of the enclosure space 40 through the sunlight extraction opening 50. Are reflected one after another by the reflecting plates 61 to 73, and are guided to the inner wall space 44, which is the cabin space 41, the inner wall space 45, the underfloor space 42, and the northern housing space 40 in the enclosure space 40. It is set so that the space 41, the inner wall space 45, the underfloor space 42 and the inner wall space 44 are irradiated.

  Further, the reflecting plate 61 reflects the sunlight that has entered the cabin space 41 through the sunlight collecting opening 50 toward the reflecting plate 62 (light guiding position), and the sunlight collecting opening. 3 is rotated (displaced) by a driving device (not shown) between the position shown in FIG. 3 (light-shielding position) in which sunlight incident on the cabin space 41 through the section 50 is reflected toward the sunlight collection opening 50. It is configured to be able to.

  When the reflecting plate 61 is located at the light guide position shown in FIG. 2, the sunlight incident from the sunlight collecting opening 50 is reflected one after another by the reflecting plates 61 to 73, and the hut space 41, the inner wall space 45, and the floor below. The light is guided to the space 42 and the inner wall space 44, and irradiated to the hut space 41, the inner wall space 45, the underfloor space 42, and the inner wall space 44.

  On the other hand, when the reflecting plate 61 is located at the light shielding position shown in FIG. 3, the sunlight incident from the sunlight collecting opening 50 is reflected toward the sunlight collecting opening 50 by the reflecting plate 61, and sunlight collecting is performed. The light is emitted (guided) from the opening 50 to the outside. That is, the sunlight is not substantially irradiated to the enclosure space 40.

  As the reflectors 61 to 73, it is preferable to use a reflector having a reflective surface with a high reflectance. Specifically, the reflectance of the reflecting surfaces of the reflectors 61 to 73 is preferably 95% or more, and more preferably 98% or more. Moreover, as a constituent material of the reflecting plates 61 to 73 (a constituent material of the reflecting surfaces of the reflecting plates 61 to 73), for example, a metal material such as aluminum or an aluminum alloy can be used.

  By using the reflecting plates 61 to 73 having a reflective surface with a high reflectance, the loss of sunlight guided by the light guide unit 60 can be suppressed, and sunlight can be guided efficiently. Can do.

  Thus, in this irradiation apparatus 1, sunlight does not reach and, for example, fungi such as fungi, bacteria, pests (insects) such as mites, spiders, cockroaches, white ants, and small animals such as rats live, adhere and breed. The shed space 41, the inner wall space 45, the underfloor space 42, and the inner wall space 44, which are easy places, can be irradiated with sunlight collected through the sunlight lighting openings 50.

  Thereby, repelling and extermination of fungi such as fungi and bacteria, pests such as mites, spiders, cockroaches and white ants, and small animals such as mice can be performed in the housing space 40 of the house 10. That is, by irradiation with sunlight, for example, adhesion and propagation of fungi such as mold and bacteria can be prevented, or the fungi can be sterilized. In addition, for example, pests such as mites, spiders, cockroaches, white ants dislike the light, and therefore, they can be repelled and exterminated by irradiation with sunlight. Similarly, for example, repelling and extermination of small animals such as mice can be performed by irradiation with sunlight.

  Further, if necessary, the reflecting plate 61 can be positioned at the light shielding position shown in FIG. 3, so that the sunlight incident through the sunlight collecting opening 50 can be shielded by the reflecting plate 61. It is possible to prevent light from being applied to the housing space 40.

  Here, in this invention, the structure of the light guide part 60 is not limited to the thing of the example of illustration, The light guide part 60 is the sunlight collected through the sunlight lighting opening part (lighting part) 50, What is necessary is just to be comprised so that at least 1 of each space which comprises the housing space 40, ie, the hut space 41, the underfloor space 42, the toilet space 43, and the inner wall spaces 44-46, may be irradiated.

  That is, in the present invention, the light guide unit 60 may be configured to irradiate substantially the entire body space 40 with sunlight collected through the sunlight collection opening 50. You may be comprised so that a part of inner space 40 may be irradiated intensively.

  When sunlight is irradiated to almost the entire housing space 40, the fungi, pests, and small animals can be repelled and exterminated in the entire housing space 40.

  Further, when sunlight is intensively applied to a part of the housing space 40, the fungi, pests, and small animals can be repelled and exterminated more reliably at that location.

Moreover, it is preferable that the light guide part 60 is comprised so that the sunlight collected via the sunlight lighting opening part 50 may be irradiated to the housing space 40 of the north side at least. The northern enclosure space 40 is a place where fungi, pests, and small animals are more likely to inhabit, adhere to, and breed than the south, east, and west enclosure spaces 40, so that the area is irradiated with sunlight. This is because a higher effect can be obtained.
Moreover, the object of repelling and extermination changes with the location which irradiates sunlight.

  In the case where the sunlight is irradiated in the hut space 41, the toilet space 43, and the inner wall spaces 44 to 46, the target of repelling and extermination is, for example, fungi such as mold, bacteria, mites, spiders, cockroaches, etc. Pests, small animals such as mice.

  On the other hand, since white ants live in a relatively low position, when the portion to be irradiated with sunlight is the underfloor space 42, the white ants are added to the above-mentioned targets for repelling and extermination.

  As shown in FIG. 1, the light irradiation device 1 further includes a window (light emitting portion) 81 that emits light (sunlight or the like) guided in the housing space 40 into the room 32 of the house 10. is doing.

The window 81 includes an opening formed at the upper corner (corner) of the inner wall portion 26 of the chamber 32, and a light-transmitting member that is fitted in the opening and has light transmission properties. Moreover, as a constituent material of the said light transmissive member, various glass, various resin, etc. can be used, for example. The window 81 may be provided with an optical component such as a diffusion plate that diffuses light.
Further, a light shielding means (not shown) that can shield the window 81 may be provided.

  As shown in FIG. 2, the window 81 can uniformly emit (irradiate) the sunlight guided by the light guide unit 60 in the housing space 40 into the chamber 32.

  As shown in FIG. 1, the light irradiation device 1 further includes a circulation device 90 that can circulate air in the housing space 40 as ventilation means for ventilating the housing space 40.

  The circulation device 90 is provided at the lower part on the left side and the lower part on the right side of the outer wall part 22 in FIG. 1, underfloor ventilation ports 91 and 92 that allow the underfloor space 42 to communicate with the outside, and the top part (center part) of the roof part And a cabin ventilation port 93 that allows the cabin space 41 to communicate with the outside. The underfloor ventilation ports 91 and 92 and the hut ventilation port 93 are configured to be opened and closed by, for example, a shutter device (not shown).

Next, the operation of the circulation device 90 will be described.
Generally, the temperature of the air in the housing space 40 of the house 10 is higher than the outside air. For this reason, as shown in FIG. 4, when the underfloor ventilation ports 91 and 92 and the hut ventilation port 93 are opened, the air in the underfloor space 42 rises, and the inner wall spaces 44, 45, 46 and the underside space 43 are moved. After that, it rises to the cabin space 41 and is discharged from the cabin ventilation port 93. On the other hand, when the air in the underfloor space 42 rises, outside air (air) flows in through the underfloor ventilation ports 91 and 92. Thus, outside air flows into the enclosure space 40 from the underfloor ventilation openings 91 and 92, flows through the enclosure space 40, and is discharged from the hut ventilation opening 93.

  Further, in the housing space 40, a temperature difference is caused by the sunlight collected through the sunlight collection opening 50. For this reason, when the underfloor ventilation ports 91 and 92 and the hut ventilation port 93 are closed, the internal air circulates (natural circulation) in the enclosure space 40 due to the temperature difference in the enclosure space 40.

  In the present invention, the ventilation means may further include an air supply device such as a fan. According to this, the housing space 40 can be ventilated more reliably.

  As shown in FIG. 1, the light irradiation device 1 further includes artificial light irradiation means including a plurality of LEDs (light emitting diodes) (artificial light sources) 100 and a driving device (not shown) that drives the LEDs 100. . Each LED 100 is installed in the housing space 40, and the artificial light irradiation means drives the LED 100 by a driving device, and supplementarily emits light (artificial light) from the LED 100 into the housing space 40. Irradiate.

  Further, the light emitted from the LED 100 is guided in the housing space 40 by the light guide unit 60 and irradiated to the housing space 40 in the same manner as the above-described sunlight.

  Thereby, the light quantity and specific wavelength of sunlight guided (irradiated) in the housing space 40 can be complemented. For example, when the sun is not emitted at night or when the weather is cloudy or rainy, the fungi, pests, and small animals can be repelled and exterminated by causing the LED 100 to emit light.

  In addition, the number and position of LED100 are not limited to what was illustrated. Further, the LED 100 may not be provided in the housing space 40.

  As described above, according to the light irradiation device 1, sunlight can be collected and the sunlight 40 can be reliably irradiated to the housing space 40.

  As a result, it is not necessary to apply an ant repellent (insect repellent) or the like in the house 10, for example, fungi such as mold, bacteria, pests such as mites, spiders, cockroaches, white ants, and small animals such as rats. And removal can be performed easily. Thereby, it is possible to live comfortably and safely in the house 10, and the durability of the house 10 can be improved.

  Moreover, since the housing space 40 becomes bright, the maintainability in the housing space 40 can be improved.

  In addition, by irradiating the housing space 40 with sunlight, the interiors of the chambers 31, 32, and 33 can be warmed through the inner wall portions 25, 26, and 27, respectively. Therefore, the rooms 31, 32, and 33 can be heated without using electric power, energy consumption can be reduced, and the house 10 can contribute to energy saving. In particular, by irradiating the entire housing space 40 with sunlight, the interiors of the chambers 31, 32, and 33 can be uniformly warmed.

  In addition, by irradiating the housing space 40 with sunlight, the interior space 40 and the inner surface of the housing 20 are warmed, whereby water vapor in the housing 20 and the like can be evaporated to prevent condensation. The housing 20 can be dried. Thereby, it is possible to improve the durability of the house 10 by preventing the decay and deterioration of the wood, the heat insulating material and the like constituting the casing 20, and to suppress the growth of fungi and pests due to moisture.

  Further, according to the light irradiation device 1, the circulation device 90 opens the underfloor ventilation ports 91 and 92 and the hut ventilation port 93, so that outside air flows into the enclosure space 40 from the underfloor ventilation ports 91 and 92, and the enclosure. Since it flows in the inner space 40 and is discharged from the hut ventilation port 93, the humidity of the housing space 40 can be reduced. Thereby, dew condensation inside the housing 20 can be prevented, the housing 20 can be dried, and the durability and durability of the house 10 can be prevented by preventing the decay and deterioration of the wood and heat insulating materials constituting the housing 20. Can be further improved, and the propagation of fungi and pests due to moisture can be further suppressed.

  In addition, since the heat generated in the enclosure space 40 can be wasted, for example, in summer, the heat generated in the enclosure space 40 when the sunlight is irradiated to the enclosure space 40 to the outside. Can be waste heat. Thereby, the temperature in chamber 31,32,33 can be lowered | hung and the comfort in chamber 31,32,33 can be improved.

  In addition, since it is possible to prevent the interior of the rooms 31, 32, 33 from becoming too hot without increasing the set temperature of the cooling or using the cooling, energy consumption can be reduced, and the house This can contribute to 10 energy savings.

  In addition, when the circulation device 90 closes the underfloor ventilation ports 91 and 92 and the hut ventilation port 93, the internal air can be naturally circulated in the enclosure space 40 due to the temperature difference of the enclosure space 40. For this reason, the temperature in the housing space 40 can be made uniform. In particular, in winter, by circulating the air heated by the sunlight irradiated to the enclosure space 40 in the enclosure space 40, the entire enclosure space 40 can be uniformly heated, and the entire house 10 is heated. There is no difference, and it can warm up uniformly.

  Moreover, according to the light irradiation apparatus 1, since the reflecting plate 61 of the light guide part 60 is comprised so that rotation between the light guide position shown in FIG. 2 and the light-shielding position shown in FIG. By rotating 61 and changing the position of the reflecting plate 61, the optical path of the light guided in the housing space 40 can be changed. Thereby, regardless of the incident angle of sunlight according to time and season, the sunlight incident through the sunlight collecting opening 50 can be surely guided in the housing space 40, and the sunlight can be reliably transmitted to the housing space 40. Can be irradiated.

  Further, by positioning the reflecting plate 61 at the light shielding position shown in FIG. 3, the sunlight incident through the sunlight collecting opening 50 is reflected by the reflecting plate 61 and externally passed through the sunlight collecting opening 50. Can be released (can be shielded from light).

  Further, by adjusting the position of the reflecting plate 61 by rotating the reflecting plate 61 between the light guide position shown in FIG. 2 and the light shielding position shown in FIG. The amount of light can be adjusted. Thereby, the temperature adjustment can be performed by adjusting the strength of the heating of the housing space 40 by sunlight, that is, the heating of the house 10.

  Moreover, according to the light irradiation apparatus 1, the light (sunlight etc.) light-guided in the housing space 40 can be radiated | emitted in the chamber 31 by the window 81, Thereby, an indoor can be illuminated. it can. Thereby, power consumption can be reduced. In addition, sunlight can be taken into a room with poor sunlight, such as a room on the north side or a room without windows, and the comfort of the house 10 can be improved.

  Moreover, according to the light irradiation apparatus 1, since the common housing | casing space 40 is utilized as a light guide path of sunlight, and a flow path of air, it can contribute to the space-saving of the house 10. FIG.

  Moreover, according to the light irradiation apparatus 1, since several LED100 is arrange | positioned in the housing space 40, the light quantity and specific wavelength which are light-guided (irradiated) in the housing space 40 are supplemented. can do.

  Thereby, in the house 10, repelling and extermination of fungi, pests, and small animals can be performed more reliably. In particular, fungi, pests, and small animals can be repelled and exterminated by causing the LED 100 to emit light even at night or when the sun does not appear, such as when the weather is cloudy or rainy.

In addition, the interiors of the rooms 31, 32, and 33 of the house 10 can be further warmed, and condensation within the housing 20 can be more reliably prevented.
