The lighting groove 3 is arranged by arranging a plurality of vertical frames according to the width of the lighting groove 3 and arranging a plurality of horizontal frames according to the height of the lighting groove 3 so as to straddle these vertical frames. It may be formed.
The depth of the stepped portion 4 is shallower than about half of the thickness of the panel body 2, and the length from the surface 5 b of the translucent member 5 to the locking surface 50 a of the locking portion 50 with the stepped portion 4 is substantially equal. It is formed as follows.
In addition, although FIG.1 (b), FIG.4 etc. show the example in which the step digging part 4 was formed in the core material 21 which comprises the vertical frame of the panel body 2, the step digging part 4 is the core material which comprises a horizontal frame. 21. In this case, the locking portion 50 of the translucent member 5 is provided so as to correspond to the position of the stepped portion 4.
In FIG. 4B, the depth of the stepped portion 4 is indicated by 4a, and in FIG. 4C, the length from the surface 5b of the translucent member 5 to the locking surface 50a of the locking portion 50 is 5a. Is shown. Therefore, it is desirable that 4a = 5a. According to this configuration, it is possible to provide the daylighting panel 1 in which the surface 5b of the translucent member 5 and the surface 20a of the panel body 2 are flush with each other.

Next, the translucent member 5 will be described with reference to FIGS. In addition, in FIG. 2, although the hatching of the translucent member 5 is not attached | subjected for description, sectional drawing is shown.
The engaging portions 50 formed on both side surfaces of the translucent member 5 only need to be engaged with the stepped moat 4, and here, the engaging portions formed in a protruding shape in the inner surface direction of the stepped moat 4. 50 is shown.
Further, it is desirable that the side surface of the translucent member 5 provided with the locking portion 50 is formed with an inclined surface 51 that reflects light incident from the surface 5b side of the translucent member 5. The inclined surface 51 is formed so as to be gradually narrowed from the surface 5 b side of the translucent member 5 toward the locking portion 50.

The translucent member 5 is disposed so that the above-described surface 5b is flush with the surface of the panel body 2 so that light enters and exits the inside and outside of the daylighting panel 1. At this time, the light-transmitting member 5 faces the surface 5b. The locking portion 50 is disposed at the position, that is, the inner side of the daylighting panel 1.
Further, the translucent member 5 includes a side surface portion 52 that is fitted in a state in contact with the inner side surface of the stepped moat portion 4 from the surface end portion of the translucent member 5, and more preferably, as shown in the drawing, It is good also as what was provided with a pair of protrusion part 53 formed so that it might be inserted in the state contact | abutted along the inner surface of the lighting groove | channel 3. FIG.
The pair of projecting portions 53 are formed in accordance with the groove width of the daylighting groove 3, and in the case of being provided with this, the fitting force of the translucent member 5 to the stepped portion 4 can be further strengthened.
