PROBLEM TO BE SOLVED: To provide a luminaire having maximum lighting efficiency with minimum power consumption and energy cost, as well as maximum reflected light output for increasing the service life of lighting facilities while reducing the greenhouse effect level of an lighting space. SOLUTION: The luminaire 20 with a light reflecting structure includes a casing 30 having at least one opening type storage space 31 for emitting a light beam to the outside, a plurality of paired sockets 40 whose lamps 60 are connected to the casing 30 and which are symmetrically installed on the both-end longitudinal sides of the storage space 31, and a reflecting member 50 having a curved face to which a composite light reflecting specular film is pasted, and located in the storage space 31 to substantially cover at least part of the surface of the storage space 31. In accordance with a law of reflection, the contour of the curved face of the reflecting member 50 is determined to optimize the transmission amount of primary reflected light reflected by the reflecting member 50 to be 90% or more of the transmission amount of naked light of the lamps 60.
