How does the lamp line connect
The one that used to be in the early part of the world, which requires the regenerator to cooperate with the light, is an inductance ballast, and the fluorescent tube now needs to glow without the regenerator. The ballast that doesn't need a regenerator is an electronic ballast. Ask to sell tubes of the owner, they all know and electronic ballast inductance ballasts, now basically eliminated inductance ballasts, everybody understand the electronic ballast is enough. If it is an old lamp, it will meet the inductive ballast. The lamp tube has two feet on each side, and the left and right sides are four feet
If it is converted by fluorescent lamp tube into LED lamp tube, want to remove the regenerator and the ballast. The two wires connected to A1 and A2 have been turned into a thread, and the two wires connecting B1 and B2 are also twisted into one line and are connected to the two ends of 220V respectively.
Briefly said, fluorescent lamp need to shine at the beginning of the start to a transient high pressure, the pressure is greater than 220 v, ballast can produce the instantaneous high pressure, help the fluorescent lamp. Before the lamp to shine, in addition to need ballast, also need a starter starter (scientific name:), like many tubes above the starter without this now,
If the lamp is ordinary lamp, that is the kind of tubes, tube wall coated with phosphor is need ballast, if it is a led lamp, does not need ballast, later I'll detail
