PROBLEM TO BE SOLVED: To obtain a partial illumination capable of adjusting an illumination angle from a socket for an interior down light without interior work. SOLUTION: A female side base part 6 provided with a socket part including a pair of terminal points 6a and 6b for spirally fitting a base part 4a of an electric bulb 4 and a male side base part 5 provided with a base part 8 including a pair of terminal parts for spirally fitting a lamp socket 3 are connected by means of a flexible connecting arm 7. A pair of the terminal points 6a and 6b of the socket part with which the female side base part 6 is provided and a pair of the terminal points of the base part 8 with which said male side base part 5 is provided are made electrically conductive at a pair of conductors 11a and 11b provided along the connecting arm 7. Turning on/off is made possible by means of operation of an interior side power switch, and an illumination angle and an position can be arbitrarily adjusted by adjusting the connecting arm. |
