Description

Ballast for Fluorescent Lamps {Ballast}

The present invention relates to a ballast for fluorescent lamps. More specifically, the present invention relates to a ballast for fluorescent lamps, in which a socket including a connection pin is formed on one side of the ballast, and a socket including a connection groove is formed on one side of the luminaire connected to the ballast to couple the ballast to the luminaire. .

Fluorescent lamps are a type of discharge tube that require a high voltage at the initial stage of lighting to emit electrons necessary for discharging, and have a negative resistance characteristic that the voltage applied to the fluorescent lamp decreases when the current flowing through the fluorescent lamp increases after discharge. have. Therefore, a light source that converts electrical energy into light energy using a discharge phenomenon, including a fluorescent lamp, requires a lighting circuit, ie, a ballast, that lights up a lamp due to such negative resistance characteristics. The ballast supplies the lamp with a high voltage necessary to turn on the lamp at the beginning of the lamp, and after the lamp is turned on, it controls the amount of current supplied to the lamp so that the lamp maintains a constant brightness. These ballasts have a direct impact on the lifetime and efficiency of fluorescent lamps.

On the other hand, ballasts used in fluorescent lamps include magnetic ballasts and electronic ballasts. Magnetic ballasts have a low manufacturing cost but are composed of an iron core and a coil, which is heavy and consumes a lot of power. The electronic ballast has a high manufacturing cost, but is composed of semiconductor devices, which is light and consumes less power. In particular, the electronic ballast employs an inverter circuit oscillating at a high frequency, thereby greatly reducing flicker that frequently occurs in the magnetic ballast. Due to these characteristics, electronic ballasts are becoming more common than magnetic ballasts in recent years.
