Abstract
The invention relates to an electronic ballast of an efficient energy-saving fluorescent lamp in an electric lighting device. The electronic ballast comprises a boosted circuit and a rectifying drive circuit, wherein three capacitors are added to the boosted circuit; and a lamp tube glows slowly with the charge and saturation process of the capacitors, pulse current does not exist and the preheating time is sufficient, thereby doubling the service life of the lamp tube. In the rectifying drive circuit, four diodes are connected with two ends of the lamp tube end to end; and the diodes are rectified to obtain a higher direct current voltage. The electronic ballast has the advantages of simple structure, fewer components, low cost, light weight, low glowing voltage, high startup speed, no flashing, noise or interference, low power consumption, long service life and the like.
Description
Technical field
The present invention relates to a kind of fluorescent lamp ballast, especially a kind of energy-efficient electric ballast.
Background technology
Be mainly used at present the electric ballast of fluorescent lamp on the market, exist the inductance type ballast AC noise big in long-term use, it is uncomfortable to allow the user listen, and also disturbs the normal use of other household electrical appliances easily; On the other hand, though comparing incandescent lamp, fluorescent lamp has advantages such as luminous efficiency height, power saving, but frequent flicker is arranged when fluorescent lamp is turned on light, and the long-time flicker of fluorescent tube damages easily, and it is narrow to adapt to voltage range, incompatibility rural area, the place that outlying mountain area's voltage is low, and incompatibility network transformer backguy place far away excessively, voltage is too low can not normally to be started, and toggle speed is slow, power factor is low, power consumption is big, also has electronic circuit complexity, problem that cost is high in addition.
Summary of the invention
The purpose of this invention is to provide that a kind of circuit is simple, components and parts are few, opening speed is fast, flicker free, energy-saving effect is obvious, a kind of energy-efficient electronic ballast for fluorescent lamp that the fluorescent tube filament can also use after having lacked as usual.
The object of the present invention is achieved like this: be made up of booster circuit and rectification drive circuit.Booster circuit is by two capacitor C
