In general, in the case of a luminaire used to illuminate a room, light is generated by charging a gas or fluorescent material inside an incandescent lamp or a glass tube that generates light by generating resistance from a filament with a lamp, and then discharging the charged fluorescent material. Use a fluorescent lamp to generate.

In addition, the lamp may be divided into a method of connecting the electrodes by forming a terminal at the end and inserting it into the socket, and a method of forming the terminal in a spiral shape and inserting it by rotation. Among the above methods, a polarizing (PL) lamp, a three-wavelength lamp or a fluorescent lamp which forms a terminal at the end of the bulb and inserts it into the socket is generally widely used.

However, in the case of such fluorescent lamps, the light emitted by the discharge in the low-pressure mercury vapor causes a phenomenon in which the voltage required for the discharge falls when a current flows, thus causing a discharge by applying a constant voltage. At this time, if the current is excessively increased, there is a possibility that the lamp may be destroyed, and in order to supply the current stably, the ballasts are used in series.
