Abstract

The invention discloses a novel dual-end single-pole circuit of an electronic ballast for a fluorescent lamp. The novel dual-end single-pole circuit comprises a common mode inductor, a full-bridge rectification circuit, a filtering and shaping circuit, an oscillation circuit, an open circuit protection circuit and a lamp tube protection circuit, wherein an input end of the common mode inductor is connected with a fuse wire and an inductor L4 and is connected with an L pole of an alternating current 220v; the other end of the common mode inductor is connected with an N pole of the alternating current 220V. According to the novel dual-end single-pole circuit of the electronic ballast for the fluorescent lamp, protection circuits are completely designed for the circuit; the novel dual-end single-pole circuit has the functions of open circuit protection, overcurrent protection and overheat protection. A single-pole high-efficiency electronic ballast for the fluorescent lamp has the advantages of being high in efficiency, long in service life and soft in light ray, being environment-friendly and energy-saving and protecting an eye, and the like.

Description

technical field [0001] The invention relates to the technical field of electronic ballasts, in particular to a novel electronic ballast circuit for double-ended unipolar fluorescent lamps. Background technique [0002] Fluorescent lamp is the most widely used lighting source at present, but its starting current is large, the temperature at both ends of the lamp tube is high, it is easy to make both ends of the lamp tube black, and the filament at either end of the lamp tube is blown, which will cause the report fee of the lamp . In recent years, various electronic ballasts for fluorescent lamps have been launched on the Chinese market. There is no major breakthrough in its principle and structure. There are local strong light that hurts the eyes, insufficient illumination in the space, long time from the beginning of lighting to normal lighting, short service life, and no obvious energy-saving effect. The shortcomings of the previous technology are mainly that the output ...
