What Are The Electric Ballasts Function

Fluorescent lamps have a variety of uses, from office lighting to home lighting. The typical fluorescent lamp contains a mercury vapor discharge tube and two electrodes. When the lamp is turned on, current flows through the electrodes, heating them. The heated electrodes cause the mercury vapor in the tube to emit ultraviolet light that strikes phosphor coating on the inside walls of the glass tube. This causes a blue-green glow called fluorescence which produces visible light that exits through a clear glass cover at one end of each tube. In order to increase efficiency, modern fluorescent lamps use an electric ballast that controls current flow through coils within its housing (see diagram).

Electrical Ballast Function

The electric ballast function is used to control the current flow in fluorescent lamps. The electric ballast is a device that converts the AC power from the mains supply into DC current for the fluorescent lamp, and also helps stabilize its operation by providing a constant voltage. The function of an electronic ballast is to provide stable starting, running and operating conditions for fluorescent lamps. An electronic ballast (or electrical ballast) is a device that controls the starting voltage and the operating currents of lighting devices. It does this through the principle of electrical gas discharge. An electronic ballast will convert power frequency to a very high frequency to initialize the gas discharge process in Fluorescent Lamps by controlling the voltage across the lamp and current through the lamp.

Characteristics Of The Electrical Ballast

  • The characteristics of the electric ballast are very stable, high efficiency and long life.
  • The power supply to the lamp is stable and steady, which can ensure that the burning position of lamps is consistent and reliable.
  • Due to its low power consumption, it saves energy and reduces operating costs for users by 50%.

In addition, the electric ballast function can be used for general fluorescent lamps and high-power mercury vapor lamps. It is widely used in supermarkets, offices, schools and other places. At the same time, electronic ballasts usually have the function of a starter, so they can save money for a separate starter. Electronic ballasts can also have more functions, such as improving or eliminating the flickering phenomenon of fluorescent lamps by increasing the current frequency or current waveform (such as a square wave). It can also make fluorescent lamps use DC power through the power inversion process.

When Used For The Lamp Switch

The ballast is a switch for the lamp. When it is used, it can be considered as a switch for the lamp. The function of this ballast is to control the current and voltage of an electric circuit. This is done by converting the alternating current of electricity into direct current. This is important because it allows the lamp to work efficiently and effectively. The ballast has a variety of applications in different industries. It is used in fluorescent lights, high-intensity discharge lamps and other kinds of lamps. The ballast also helps to regulate the amount of current flowing through the lamp and makes sure that it stays within safe limits.

Important For The Fluorescent Lamps

Electric ballasts are used to control the current flow in fluorescent lamps. They can be used as a switch for the lamp, or they may act as an electronic device that converts alternating current (AC) electricity into direct current (DC).

As a result of this conversion process, they produce an electromagnetic field around them when they are turned on. This field is strong enough to induce an electric current within any nearby conductive materials such as metal tubes and wires inside your fluorescent light fixture; it also helps regulate how much voltage gets sent through those materials so that your lights don’t overheat or burn out too quickly.


Electronic Ballast is a kind of ballast, which uses electronic technology to drive the electric light source to produce the required lighting. Corresponding to it is the inductive ballast. More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and people can even integrate electronic ballasts with lamps. In summary, the electric ballast is an important component used to control the current flow in fluorescent lamps.
