PURPOSE:To connect a luminous tube with a trigger terminal by means of a contraction-deformable electric connecting spring member instead of a lead wire, by providing the electric connecting spring member, whose one end is pressure-contacted with the NESA-coated section of the luminous tube and the other end is pressure-contacted with a stationary member, and installing the trigger terminal to the static member. CONSTITUTION:A coil-spring-like electric connecting spring member 3 having an outside diameter which is smaller than the inside diameter of a cylindrical projecting section 5c is inserted into the section 5c and the front end of the spring member 3 is pressure-contacted with the NESA-coated section on the outer peripheral surface of a luminous tube 2 in a reflector 1. The rear end of the spring member 3 is pressure-contacted with a conductive piece 8 fixed to the inner end face (namely, the front face of a vertical section 5B) of the cylindrical projecting section 5c. The conductive piece 8 is extended to the outside beyond the projecting section 5c from the inside of the projecting section 5c through a notch 5f and connected with a trigger terminal. Therefore, a trigger voltage is impressed across the luminous tube 2 from the trigger terminal through the conductive piece 8 and connecting spring member 3.
