  Moreover, although the illumination part 3 which has the light source 6 is inserted in the through-hole 21a of the wall material 10 for construction, you may insert the other electric appliance connected to the 2nd terminal part 23b in the through-hole 21a. For example, an electrical appliance such as an outlet or a lighting rosette can be inserted into the through hole 21a.

  The present invention can be used for building wall materials such as ceiling walls and partition walls.
