PROBLEM TO BE SOLVED: To improve efficiency of a luminaire and eliminate the mounting directiveness. SOLUTION: This luminaire is composed of having a main reflecting mirror 1 provided with a paraboloid of revolution shaped reflecting surface part 1a formed so as to open to its front face side and to extend from a base part side to the front face side and two lamps 2 which are two light emitting tubes 2a roughly parallel to the axial direction of the reflecting face part 1a of the main reflecting mirror 1 and so arranged as to extend from the base part side to the reflecting face side 1a side inside the main reflecting mirror 1. In this case, an auxiliary reflecting mirror 5 is provided composed of a rotation curve face formed into its roughly cylindrical shape in which one end is narrow and is positioned on the base part side in a roughly equal distance from the two lamps and the other end side is wide and is positioned on the base part side of the reflecting face part 1a, on the side face side which is on the base part side of the main reflecting mirror 1 and is separated in the vertical direction on a face including the two lamp 2, and formed by revolving a curve so as to extend to the outside from the base part side to the front face side. |
