Abstract: PROBLEM TO BE SOLVED: To provide an electric shock prevention fluorescent lamp capable of making a user safely perform mounting work by the same procedure as a conventional fluorescent lamp.SOLUTION: The electric shock prevention fluorescent lamp includes a body and two bases. The body has a light-emitting module. Each base has a first connection terminal, a first safety switch, an elastic conductive unit, and a second connection terminal, and the bases are respectively arranged on both sides of the body. When the electric shock prevention fluorescent lamp is mounted, the safety switch can deform the corresponding elastic conductive unit if either of the safety switch receives a pressure force, and the elastic conductive unit and the corresponding second connection terminal are electrically connected. Thus, the first connection terminal and the second connection terminal are conducted each other. When the pressure force applied to the safety switch is opened, the deformed elastic conductive unit pushes the safety switch in a direction opposite to the pressure force, and the first connection terminal and the second connection terminal become in a disconnected state.
