Abstract

The invention discloses an energy-saving type fluorescent lamp, the structure of which includes that the two sides of a casing pipe are respectively connected with a casing pipe seat, locators and a power connector; the casing pipe seat is sheathed on the casing pipe of a fluorescent tube and a third PCB is installed on the casing pipe seat; the casing pipe seat is clamped and connected with the locator and the cable contact of the third PCB is installed between the casing pipe seat and the locator. A second PCB is connected between the locator at one side and the power connector while a first PCB is connected between the locator at the other side and the power connector. The PCBs are connected with power terminals of the fluorescent tube in the casing pipe and four connecting lines in the fluorescent tube. A ballast circuit of the energy-saving type fluorescent lamp of the invention is installed outside the casing pipe and convenient for disassembly and replacement. When in replacement, the fluorescent tube in the casing pipe is not required to be assembled so as to be convenient for disassembly and reduce maintenance cost; furthermore, the main components of the energy-saving type fluorescent lamp can be recycled.
