Description

technical field [0001] The invention belongs to the field of electronics, in particular to an energy-saving conversion head for an inductive fluorescent lamp. Background technique [0002] Electronic ballasts for ordinary T5 fluorescent lamps have some problems, such as blackheads on the lamp tube, low power factor, large current harmonic content, and substandard crest factor. There is also a problem in matching the electronic ballast with the T5 fluorescent lamp. The main reason for the scrapping of the lamp is that the output circuit inductive reactance and capacitive reactance do not match, causing circuit resonance. The emitting material on the pole is oxidized or depleted and can no longer emit electrons, causing the cathode coil to break and cannot emit light. [0003] The existing T8 inductive fluorescent lamp is transformed into an electronic ballast for a T5 fluorescent lamp. Its circuit is the same as that of an ordinary T5 fluorescent lamp. The original T8 induc...
