NON FLICKERING FLUORESCENT LAMP

摘要

In a fluorescent lamp, it is known to have a fluorescent tube connected in series with an induction coil (choke), plus ignition device. This circuit is connected to a source of alternating voltage. The fluorescent tube produces light, which flickers with twice the frequency of power lines. For 60 Hz supply voltage this gives 120 Hz flicker (full ON and full OFF). Flickering is straining for the human eyes and for rotary/oscillatory movements produces stroboscopic effects, which may be deceiving and dangerous. In this invention, the fluorescent tube gets DC (direct current) constant voltage from work capacitor via induction coil. Work capacitor gets voltage from rectifier. The rectifier gets AC (alternative current) alternative voltage from power lines via capacior in series. That capacitor in series limits the power drawn by the fluorescent tube. The lamp produces steady light.
