Problems solved by technology

[0003] For this reason, people invented electronic ballasts, but in actual use, electronic ballasts have a short service life, and some even have regular strobes and large harmonic content. Although they save electricity compared with magnetic ballasts, the magnitude of power saving Not big, so it is necessary to improve the existing fluorescent lamp lighting

Abstract

The present invention relates to illuminating lamps. Concretely speaking, the invention is an energy saving device for lighting. This device comprises energy saver, lighting tube and inductive rectifier. The output circuit of the energy saver is connected to the lighting tube. The input end of the energy saver is connected to power source, or an inductive rectifier is connected between the input end of the energy saver and the live wire of the power source; the energy saver comprises EMC circuit, bridge rectifier circuit, filter circuit, trigger circuit and output circuit that are connected one by one. The connection between the filter circuit and the output circuit has an abnormal protection circuit. The output circuit is also connected to the high frequency output sub-circuit in the switch converter circuit. This device may obviously raise the illuminating brightness of the lighting tube and maximally increase the luminous efficiency or luminous flux of the lighting tube by above 50%, while lower power consumption by 50%-70% and reduce the harmonic content in circuits.

Description

technical field [0001] The invention relates to an illuminating lamp, in particular to an illuminating energy-saving device. Background technique [0002] After the invention of fluorescent tubes, the use of magnetic ballasts and white light tubes for lighting has occupied a considerable period of time in the field of lighting, so that in people's daily life and work, most of the places where fluorescent tubes are used for lighting are used The way the magnetic ballast is matched with the lamp tube. The lamp tube of this lighting system has low luminous efficiency, high power consumption, and low power factor. Especially when the circuit voltage is low, it is easy to produce stroboscopic flicker visible to the naked eye, which greatly harms people's eyes. [0003] For this reason, people invented electronic ballasts, but in actual use, electronic ballasts have a short service life, and some even have regular strobes and large harmonic content. Although they save electricity...
