Abstract

A long-life self-ballasted energy-saving fluorescent lamp belongs to the illuminating electric device field, comprising a double U-shaped lamp tube, a plastic component fixing the lamp tube, a lamp holder on the lower end and an electronic circuit plate arranged inside the plastic component, wherein a ballast circuit on the electronic circuit plate is provided with three inductive coupling coils according to the fixing turns ratio, and the inductive coupling coils and an output capacitance compose a resonance voltage amplitude with the fluorescent lamp tube; and the layout direction and the position of each inductive coupling coil on the circuit plate are regulated in the best coupling condition. Since the resonance loop formed by the self-ballasted circuit on the electronic circuit plate inside is more adapted to the voltage parameter of the fluorescent lamp tube and at the same time the layout of the elements on the electronic circuit plate is regulated in the condition of the smallest electromagnetic interference signal, the fluorescent lamp tube avoids the instant flickering when started and apparently increases the operating life and the stability.

Description

Long-life is from the ballast energy-saving fluorescent lamp

Technical field

The utility model belongs to power for illumination tool field, specially refers to a kind of long-life from the ballast energy-saving fluorescent lamp.

Background technology

The various power saving fluorescent lamps of Xiao Shouing are very general in the market, has plenty of external ballast, have plenty of and packed in the fluorescent tube from ballast, but most power saving fluorescent lamps can not obtain user's satisfaction on useful life, when the moment of opening switch, most fluorescent tubes will flash stable light of one or two time ability, so flashing repeatedly, have more than is needed lamp tube end that how long will make turns black gradually, come to an end useful life, the fluorescent tube that has is under instantaneous impact of flashing, can make open filament very soon, end-of-life, the design people by for many years to the manufacturing of electricity-saving lamp research, innovation research from the element optimal placement scheme of the optimal circuit scheme of ballast and the circuit board that adopted, make the optimum Match state of their acquisitions and U-shaped fluorescent tube parameter, make circuit electromagnetic interference to external world drop to bottom line, bigger raising lamp luminescence efficient and brought up to 8000 hours the average life of fluorescent tube, than the similar electricity-saving lamp of selling on the market tangible progressive has been arranged.

Summary of the invention

The utility model technical issues that need to address are, at existing in the ballast energy-saving fluorescent lamp, ballast circuit element and parameter thereof are selected not match with U-shaped fluorescent tube parameter, starting moment generation build-up of luminance flashes, cause critical defects such as the life-span is very brief, and redesign a kind of can with the suitable ballast circuit of U-shaped fluorescent tube parameter and the layout of element, overcome flashing when starting, significantly improve the useful life of electricity-saving lamp, saves energy.The purpose of this utility model, realize by the following technical solutions, a kind of long-life is from the ballast energy-saving fluorescent lamp, the plastic that comprises a dual U-shaped fluorescent tube, fixed lamp tube, the lamp holder of lower end and device is characterized in that at the electronic circuit board of plastic inside, on the described electronic circuit board in the ballast circuit, be provided with three by the fixing inductance-coupled coil of turn ratio, the resonant tank that they and output capacitance constitute has the resonance potential amplitude that is complementary with fluorescent tube; Layout direction, the position of adjusting each inductance-coupled coil on the wiring board are the Best Coupling state.Described Best Coupling state is meant that the direction position of adjusting each inductance-coupled coil makes its peripheral detected electromagnetic interference signal for minimum; Described fixedly three inductance-coupled coils of turn ratio of pressing, their ratio is followed successively by L1: L2: L3 is 4: 4: 10; They and output capacitance constitute resonant tank, because output capacitance changes present 3300P into by original 2200P, the voltage amplitude that the new resonant tank that constitutes produces behind its resonance more can be complementary with the startup amplitude that fluorescent tube needs, therefore improved ballast circuit will make fluorescent light avoid flashing of instantaneity, realize the effect of stable starter.The beneficial effects of the utility model are, because the resonant tank of forming from ballast circuit on the internal electron wiring board more adapts to the voltage parameter of fluorescent tube, component placement is adjusted to and is detected electromagnetic interference signal minimum state in the indication on the electronic circuit board simultaneously, therefore fluorescent tube has been avoided instantaneous and has been flashed when starting, and has significantly increased useful life and stability.
