Claims

[Scope of utility model registration request]

A duct-shaped light guide path has a lighting entrance located outdoors at one end and is bifurcated in the middle and has a lighting exit at each branch. Each base end is supported on the rotation axis, and each rotates between an angle that closes a part of the exit of the common path portion of the light guide path and an angle that opens the exit and reflects light toward each of the branch paths. A daylighting device equipped with a pair of variable reflectors.
