し、太陽光の利用率が悪いという欠点がちり九。FIG. 1 is a sectional view showing a conventional example of this type, in which an opening 2 provided on the roof l of a building is covered with a dome-shaped lighting part 8 made of a translucent material such as transparent or milky white. In such conventional daylighting devices, sunlight is utilized only in the area between two tree arrow lines a and b in the figure, and the lower the solar altitude, the less sunlight is introduced indoors. However, the drawback is that the utilization rate of sunlight is poor.
本発明はかかる欠点に鑑みなされたもので、その目的と
するところは、採光率を改善した採光装置を提供するに
ある。The present invention has been made in view of these drawbacks, and an object of the present invention is to provide a lighting device with improved lighting efficiency.
以「、本発明を図示の実施例に基づき説明する。Hereinafter, the present invention will be explained based on illustrated embodiments.

状に形成されＣいる。FIG. 2 is a sectional view showing an embodiment of the daylighting device according to the present invention, and FIG. 8 is a perspective view. The lighting device consists of a cylindrical part 4 and a ceiling part 5 made of a translucent material.The outer surface of the cylindrical part 4 is formed in the shape of a Fresnel lens, and sunlight (arrow line) passes through the opening 2. The refracted sunlight does not focus on one point, and if the refracted light is focused at a considerable rate, it is designed to be hollow and in the Toko state. Further, the ceiling portion 5 is formed in a dome shape.

Among sunlight d and e, sunlight c and d which would not enter the indoor space as shown by the broken line if they went straight are also refracted by the Fresnel lens of the cylindrical part 4 and introduced into the indoor space through the opening 2 as shown by the solid line. Become. Therefore, the amount of sunlight incident indoors increases by ``C%'' compared to the conventional one, and a lighting device with an improved daylighting rate can be obtained.

れる付加的効果を有する。FIG. 4 is a cross-sectional view showing a different embodiment, and the configuration different from the above embodiment is that the portion from the opening end of the cylindrical portion 4 up to a certain height (the portion indicated by reference numeral 6 in the figure) is not shaped like a Fresnel lens, This is because the cylindrical transparent part is used. The height of the cylindrical transparent portion 6 is determined by the solar altitude. for example,
Assuming that the right side of the paper in FIG. It is sufficient to extend the distance up to the point where the arrow line f intersects the cylindrical portion 4. Further, restrictions on sunset (arrow line 11) can be set in the same way. In such a case, there is an additional effect of saving labor in designing and processing the Fresnel lens.

The inner surface of the C5 sun would have been used as a reflecting mirror 7.
C is a sloping rocky part A, and sunlight from the north side is rarely used. Therefore, by making a part of the inner surface of the cylindrical part 4 the reflecting mirror 7 as described above, @5 Fig. 1c
), sunlight that would otherwise escape through the cylindrical portion 4 can be introduced indoors as shown by the arrow i in FIG.
