How to distinguish the four leads of the fluorescent lamp electronic ballast line. Is there a pick up the
The fluorescent-lamp electronic ballast line is divided into two groups of four leads, each of which is connected to two lines in one end of the fluorescent lamp.
The fluorescent-lamp electronic ballast line is divided into two groups of four leads, each of which is connected to two lines in one end of the fluorescent lamp.
Fluorescent lamp electronic ballast for the four pillars that lead the horizontally, the left two "1 and 2" as a group, two on the right of a set of 3 and 4, corresponding to the two wires at the ends of the tube. If you have a lamp, you can pick up the left group or the right group. After that, the two lines will pick up. Same as the fluorescent lamp. At the beginning of the opening, "1 and 2" switch to "3 and 4", 1, 4 connect the fire line, the zero line, the filament series electricity, preheat. Then, the "1 and 2", "3 and 4" series of disconnection, produce high pressure, puncture the "panning" gas in the lamp tube, the light is bright. Again, the two filament keep a certain current, the lamp is stable and bright. These movements are performed by electronic ballast
Electronic ballast is a kind of ballast, which converts the ac power supply to high frequency ac power, which can be used to drive the electric light source and make it into the luminous state. With the advantages of energy saving and the elimination of light tube frequency, the increasingly mature electronic ballast is gradually replacing the traditional inductance rectifier.
