Japanese Patent Laid-Open No. 11-306819

  However, the conventional daylighting apparatus as described above has the following various problems. First, for example, in buildings such as factories, warehouses, stores, etc., the ceiling for attaching the irradiating means is not provided indoors, so that the light guiding means and the irradiating means extending indoors from the daylighting means can be supported respectively. Therefore, there is a problem that a daylighting device cannot be installed in the building as described above.

Secondly, when the outer diameter of the light guide means is relatively large (for example, about 500 to 600 mm), an intruder from the outside may enter the room through the light guide means.
Third, when the outside air temperature is relatively low, such as in winter, for example, the surface temperature of the light guiding means disposed on the attic of the building or the like is lower than the dew point temperature. When the contained warm air enters the inside of the diffusion cover member through the gap between the diffusion cover member and the fixing ring, and further this air flows inside the light guide means and touches the inner surface of the light guide means, the light guide Condensation occurs on the inner surface of the means. Also, in order to prevent rainwater from entering the inside of the dome member, the inside of the dome member is sealed from the outside, so that the temperature difference between the outside air temperature and the inside temperature of the dome member becomes relatively large, and the dome member The internal temperature of the becomes higher than the outside temperature. In such a case, when the dome member is cooled by the outside air and the surface temperature thereof falls below the dew point temperature, when warm air containing water vapor inside the dome member touches the inner surface of the dome member, dew condensation occurs on the inner surface of the dome member. appear. When dew condensation occurs in this way, dew condensation water adheres to the inner surface of the light guide means, the inner surface of the dome member, and the like, and there is a problem that mold or corrosion occurs on, for example, roof wood.

  Fourth, for example, when the light guide means is disposed on the attic of the building, the light guide means is set according to the relative positional relationship between the daylighting means and the irradiation means, the size of the space such as the attic, and the like. It is necessary to arrange the light guide means by bending it at a predetermined site, specifically, by connecting a tubular member bent in advance at a predetermined angle and a linear tubular member to each other. Bend at the site. However, the relative positional relationship between the daylighting means and the irradiating means and the size of the space such as the attic vary depending on the building where the daylighting apparatus is installed. There is a problem that it is necessary to prepare cylindrical members bent in advance at various angles, which increases the manufacturing cost of the daylighting apparatus. Further, for example, since the bending angle of the tubular member bent at an angle of 30 degrees cannot be finely adjusted to an angle of 35 degrees, the degree of freedom in arranging the light guiding means while bending is lowered, and the guiding member is reduced. There is a problem that the light means may not be properly disposed.

  Fifth, since the daylighting means is attached to the roof of the building, the light guide means provided between the daylighting means and the irradiation means is arranged in a space such as the attic of the building. In a building where the size of the space such as the attic is relatively small, there is a problem that it is not easy to perform the work of arranging the light guide means.

  Sixth, when snow falls on the roof of a building to which daylighting means are attached, for example, in an area where the amount of snow is relatively large, the dome member of the daylighting means is buried in the snow, and sunlight is absorbed by the daylighting means. There is a problem that it cannot be introduced.

  Seventh, since the light guide means is configured by connecting a plurality of cylindrical members to each other, the light guide means is configured according to the size of the space such as the attic where the light guide means is disposed. Although it is necessary to adjust the length of the light guide means appropriately by increasing / decreasing the number of cylindrical members, such adjustment work of the length of the light guide means is not easy, and therefore the arrangement of the light guide means is not easy. There is a problem that the installation work cannot be easily performed.

  Eighth, since the daylighting means and the irradiation means are installed in a one-to-one correspondence, when a plurality of irradiation means are provided indoors, a plurality of daylighting means are installed corresponding to each of the plurality of irradiation means. There is a problem that the installation cost of the daylighting apparatus increases.

  Ninth, since the light guide means is configured in a cylindrical shape, the light emitted through the other end of the light guide means has a light distribution that spreads in a solid square shape around the optical axis, For this reason, for example, when an irradiation unit configured in a longitudinal shape is connected to the other end of the light guide unit, the illuminance of light at both ends in the longitudinal direction of the irradiation unit is greater than the illuminance of light at the center in the longitudinal direction. There is a problem that the illuminance of light cannot be obtained uniformly over substantially the entire area of the irradiating means, and the interior cannot be properly illuminated.

Thus, the length of the light guide means 10 can be adjusted by appropriately setting the number of intermediate cylindrical members.

  Indoor lighting by the lighting device 2 configured as described above is performed as follows. Sunlight introduced through the dome member 18 of the daylighting means 8 is reflected by the concave surface side of the condensing reflection plate 32 mounted in the dome member 18 when the solar altitude is low, such as sunrise or sunset, and the inside of the light guide means 10. When the solar altitude is high, such as during the daytime, the light is guided to the inside of the light guide means 10 through the opening of the support 24. The light thus guided is reflected in a predetermined direction (the direction in which the irradiation means 14 is disposed) while being irregularly reflected on the inner surfaces of the upper cylindrical member 66, the plurality of intermediate cylindrical members 70a and 70b, and the lower cylindrical member 68. Then, the light is emitted from the other end of the lower end tubular member 68 and diffused and irradiated into the room through the diffusion cover member 38. Thus, the room is illuminated using sunlight.

When the outside air temperature is relatively low, such as in winter, the light guide means 10 disposed in the attic 76 of the building 4 is cooled by outside air, and the surface temperature thereof is lower than the dew point temperature. Since the dew condensation preventing seal member 60 is interposed in the gap between the fixing ring 42 and the diffusion cover member 38 as described above, warm air containing water vapor in the room passes through this gap and the light guide means 10 Intrusion into the interior is blocked, and this air does not touch the inner surface of the light guide means 10, thereby preventing the occurrence of condensation within the light guide means 10. In addition, since the dew condensation prevention tape member 28 is interposed between the opening of the dome member 18 and the opening of the support portion 24, the outside air forms a plurality of hairs 30 of the dew condensation prevention tape member 28. By entering the inside of the dome member 18 through the gap, the temperature difference between the internal temperature of the dome member 18 and the outside air temperature is reduced, and the occurrence of condensation within the dome member 18 is prevented. Since the occurrence of condensation is prevented as described above, the condensed water does not adhere to the inner surface of the dome member 18 or the inner surface of the light guide means 10, and the occurrence of mold or corrosion due to the condensed water can be prevented. It becomes possible. In addition, since insects and dust cannot pass through the gaps between the plurality of hairs 30, insects and dust from the outside may pass through the gaps between the opening of the dome member 18 and the opening of the support 24. Intrusion into the inside of the dome member 18 can be prevented.

  In the first embodiment, the dew condensation prevention tape member 28 is interposed between the opening of the dome member 18 and the opening of the support portion 24, thereby preventing the occurrence of condensation within the dome member 18.

Can be reduced, and the same effect as described above can be achieved. Further, since the tip tapered portion 80 is inclined radially outward and downward, the rain water sprayed from the lateral direction on the support main body 79 is rebounded by the tip tapered portion 80, and the rain water is a plurality of through holes. Intrusion into the interior of the dome member 18 through 84 is prevented. The outer diameters of the plurality of through holes 84 are preferably relatively small (for example, about 0.5 mm to 1 mm in diameter) so that insects, dust, and the like cannot pass through the through holes 84. Only one 84 may be provided.
