A lamp device with an embedded ballast is provided to decrease an implementation cost of the lamp device by arranging sockets with embedded ballasts in parallel to each other. A ballast is implemented on a socket. Socket sets corresponding to the sockets are arranged in parallel to each other. Lamps(500) are connected to each other. Plural socket sets(100) are arranged to correspond to a ballast(20) containing socket. An electric line from normal sockets is connected to an output terminal(24) of the ballast in the lamp device. An input terminal(22) of the ballast is connected to the electric line. The lamps are connected to each other. |
