PURPOSE:To prevent unevenness in the distribution of light and generation of shadow when a lamp is lighted by molding from non-translucent material a socket arm which feeds electricity to annular lamps and which holds the lamps, and molding a holding arm from translucent material. CONSTITUTION:In an annular-lamp holder 21 which is mounted to the lighting fitting main body 1 in such a manner that it is mechanically and electrically attachable/detachable therefrom, a socket arm 24 which holds lamp sockets 27, 30 by connecting them to respective lamp pins located at the mouth portions of lamps is formed from a non-translucent material the surface of which has a light diffusion property. A holding arm 25 which holds lamps by means of its holding portions 32, 33 is formed from translucent material. When lamps are lighted incident light is diffused at the surface of the arm 23 but it is not cut off at that of the arm 25 so that unevenness in the distribution of light and shadow are prevented. Moreover, exchange work of lamps is readily carried out since the holder 21 can be detached from the main body 1 without detaching a lamp therefrom. |
