Abstract

The invention is applicable to the field of fluorescent lamps, and provides an electronic ballast and a fluorescent lamp device. The electronic ballast comprises an EMI circuit, an APFC circuit and an oscillating circuit which are connected in sequence, and also comprises a controlling circuit, an output voltage regulating circuit and a protection circuit; before a fluorescent lamp is turned on, the controlling circuit controls the filament of the fluorescent lamp to be preheated; after the preheating, the controlling circuit controls the fluorescent lamp to be turned on; when the fluorescent lamp works normally, the controlling circuit regulates the operating current of the fluorescent lamp to realize light regulating control. The electronic ballast adopts the controlling circuit to control the preheating time, the preheating frequency and the turn-on time of the filament of the fluorescent lamp, prolongs the service life of the fluorescent lamp, and improves the lumen maintain; in addition, the electronic ballast can also perform light regulation control, improves the energy utilization rate, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the field of fluorescent lamps, in particular to an electronic ballast and a fluorescent lamp device. Background technique [0002] Fluorescent lamps driven by electronic ballasts are widely used due to their high luminous efficiency, energy saving and environmental protection; however, the existing fluorescent lamps generally use cold start, because the filament impedance of fluorescent lamps is extremely low, so the instantaneous current generated is very large , has a great impact on the life of electronic ballasts and fluorescent lamp tubes, and at the same time has a low luminous flux maintenance rate. [0003] Fluorescent lamps in the prior art also have a preheating design, but lack of intelligent control of the preheating time and preheating current, which will also reduce the service life of the fluorescent lamp tube. Contents of the invention [0004] The purpose of the embodiments of the present invention is to pr...
