A space is formed between the outer hanging water segments 24, and the water return waterproof wall 11 of the vertical beam 6 of the lighting body B is fitted into the space.

Further, the height from the bottom surface of the support groove 16 of the connecting members A, A' to the lower surface of the top plate 34 of the connecting member covers D, D' is made slightly larger than the height of the vertical beam 6 of the lighting body B.

Then, from the bottom of the lighting body B, the hanging leg pieces 1
3, the gap between the lower surface of the top plate 34 of the connecting member covers D, D' and the upper end of the water return waterproof wall 11 of the lighting body B, and the lower end of the hanging water section 24 of the connecting member covers D, D' A hot air discharge path communicating with the outside is formed through a gap between the upper surface of the lighting body B and the upper surface of the lighting body B.

Further, as shown in FIG. 10, the rising portion of the side reinforcing member 30 is fitted into the adjustment mounting groove 20 provided at the bottom of the connecting wall 32 of the side connecting member cover D', forming a waterproof wall. As shown in FIG. 11, if the width of the field is shorter than the standard due to the site or house structure, the adjustment installation groove 20 can be moved toward the intermediate connecting member for installation (minus adjustment installation).

As shown in Figure 12, if the field width is longer than the standard due to the site or house structure,
The (+) and (-) adjustment mounting grooves 20 can be moved toward the side connection member to be mounted (plus adjustment mounting).

In addition, as the support base in the present invention, in addition to the roof decking board, the roof base of a building or a vertical wall can be used, and it can be used as a power source for general homes, schools, hospitals, concentrated fisheries facilities, lighthouses, etc. It is something that can be done.

Effects of the Invention As described above, according to the present invention, the connecting member connects two side walls provided at an interval with a connecting wall, and the lower part of the side wall extends laterally to form a drainage groove and a support groove. Therefore, by attaching this connecting member directly on the support base, its both side walls are firmly held by the support base and the connecting wall and will not be deformed. When the body is held, since the support groove is formed at the bottom of the side wall, the distance between the supporting base and the lighting body becomes smaller than when the support groove is formed at the middle of the side wall, and there is no waste underneath the lighting body. No large space is created, and the connecting member itself can have a very simple structure.

Furthermore, since a solar cell is used as the solar energy collector, there is no need for a heat insulating structure to prevent heat dissipation, and the solar energy collector can be simplified and lightened.

Furthermore, rainwater that has entered through the support part of the daylighting element can be quickly discharged outside from the eaves through the support groove and drainage ditch, passes from the bottom of the daylighting body between the side surface of the connection member and the vertical beam of the daylighting body, and then further flows through the connection member. Since a hot air exhaust path is formed that passes below the hanging water section of the cover and communicates with the outside, hot air that is unnecessary for the solar cells in the solar energy collection device can be exhausted to the outside, increasing the efficiency of the solar cells. This makes it possible to secure a suitable living space even in the summer.
