An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.

Ballast is dense material used as a weight to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank.

2024年8月26日 · The purpose of a ballast is to control the current flow to your lamp. When you flip the switch, electricity flows through the ballast to the lamp. The ballast restricts the voltage to a safe level, so the gas inside the discharge lamps (like fluorescent or …

The meaning of BALLAST is a heavy substance (such as rocks or water) placed in such a way as to improve stability and control (as of the draft of a ship or the buoyancy of a balloon or submarine). How to use ballast in a sentence.

2025年3月4日 · It is a device that regulates the current flowing to the lamps in a lighting system. Keep reading ti more about. What's On This Page? What is a Ballast? A ballast is simply the functional part of a fluorescent or HID light source. It controls, regulates and stabilizes the light output of the fluorescent lamp.

2019年9月12日 · There are two lamp families that work with a ballast: fluorescent and HID. And there are two types of ballasts in each family: magnetic and electronic. Magnetic ballasts are the older ballast technology. For the fluorescent family, both T12 linear fluorescents and two-pin CFLs use magnetic ballasts.

2012年2月24日 · What is Electronic Ballast? An electronic ballast, also known as an electrical ballast, regulates the initial voltage and current flowing through lighting devices to ensure stable operation. It does this through the principle of electrical gas discharge.

A ballast is an electrical device that regulates the current flow to a lamp, ensuring optimal performance and longevity. Its primary purpose is to provide the necessary starting voltage to ignite the lamp and then to limit the current to a safe level during operation, preventing damage to both the lamp and the ballast itself.

2019年12月6日 · To put it simply, a ballast is the functional heart of a fluorescent or HID light source. Just as a heart regulates blood flow to your body, a ballast ensures that a lamp stays lit by managing the distribution of energy throughout the fixture. Hearts work to distribute blood via channels, or arteries, in the body to keep a body active and alive.

Ballast is a device used in electrical circuits to stabilize current and voltage for certain types of lights. It is most commonly associated with fluorescent and HID (high-intensity discharge) lamps. By regulating the current that flows through the lamp, …
