Electronic ballast (Electrical ballast), a type of ballast, refers to an electronic device that uses electronic technology to drive an electric light source to produce the desired illumination. Corresponding to this is an inductive ballast (or ballast). Modern fluorescent lamps are increasingly using electronic ballasts, which are light and compact, and can even integrate electronic ballasts with lamps. At the same time, electronic ballasts can usually have a starter function, so it can save Go to a separate starter. The electronic ballast can also have more functions, such as improving or eliminating the flickering of the fluorescent lamp by increasing the current frequency or current waveform (such as becoming a square wave), or using the DC power supply by the power inverter process.
