Abstract

PURPOSE:To reduce man-hour of wiring work by combining starting condenser with a lamp socket in a single body. CONSTITUTION:A fluorescent lamp 12 is starting-lighted by LC resonance between a condenser 20 and a stabilizer 17 which is connected to both terminals of a filament 18 on the side when it is started, thereafter, discharge-lighting is carried out between both filaments 18. When the tool is assembled, as the condenser 20 is contained inside the lamp socket 15 on one side, wires 31, 32 connect between the lamp socket 15 on one side and the stabilizer 17, and wires 33, 34 connect between the stabilizer 17 and the lamp socket on the other side. therefore, connection between the condenser 20 and the lamp socket 15 on one side is not required, and the man-hour of wiring work is reduced.
