Electrical ballast - Wikipedia
An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases.
Electronic Ballast: Working Principle & Circuit Diagram - Electrical4U
2024年5月9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.

2019年9月12日 · Electronic ballasts can put out multiple frequencies of electricity without altering the input voltage. This eliminates any flickering and buzzing. The process for swapping out …
Fluorescent Light Ballasts - Electrical 101
Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp (s). Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts.
What is a Ballast? Everything You Need to Know - LEDVANCE US
2023年3月14日 · A ballast is a device used with a lamp to obtain the circuit conditions required to start and operate, and it interacts with the lighting fixture itself to control, regulate factors such as voltage, current, and waveform, and ultimately stabilize the light output of the lamp.
Ballasts Selection Guide: Types, Features, Applications - GlobalSpec
Ballasts are power supplies or transformers for fluorescent lamps, light sources that consist of a glass tube filled with argon, neon, or other inert gas. When ballasts supply electrical current, the resulting arc emits ultraviolet (UV) radiation that excites the phosphors inside the lamp wall, causing them to radiate visible light.
111. What Exactly Is a Ballast and Why Does It Matter?
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 …
