PROBLEM TO BE SOLVED: To provide a luminaire for indirect lighting, by which the light from light sources can be radiated efficiently on a surface to be irradiated, and which can correspond to various shapes of ceiling surfaces. SOLUTION: A tilted plan 1d is formed on the upper surface of an apparatus body 1a, by forming both edges of the upper surface of the apparatus body 1a, which are parallel to light sources 1b, as they have different heights from the upper surface of a plane 4a. And the light sources 1b and lamp sockets 1c, from which an electric power is supplied to the light sources 1b, are installed on the tilted plane 1d, as they become parallel mutually. The luminaire 1 is arranged on the plane 4a of a shelf 4 installed near the lower position of a ceiling surface 2 and hidden from the lower part in a room by an erected part 4b. |
