Abstract

The utility model relates to an energy-saving type fluorescent lamp bracket. A ballast lamp holder is formed by connecting an electronic ballast with the lamp holder into integration directly on the basis of the existing lamp bracket, an induction ballast, a lamp cap, and a starter. The lamp bracket has the advantages of structural change, small volume, light weight, convenient installation and debugging, and capability of causing the starter of a luminous tube to work under the condition of below a normal voltage.

Description

The energy-saving fluorescent lamp frame

The utility model relates to a kind of fluorescence lamp bracket, specifically a kind of energy-saving fluorescent lamp frame, and it extensively adapts to 15 watts, 20 watts, 30 watts, 40 watts fluorescent tube supporting, and can make tube starting work when supply voltage is lower than normal value.

At present, traditional complete fluorescent lamp is made up of iron inductance ballast, starter, lamp socket, bracing frame.Fluorescent tube is when the beginning starter, need a higher starting voltage, its starting voltage is that the self-induction high voltage that the inductance of dependence ballast produces when the electric current that flows through it changes is suddenly realized, but when supply voltage is low, the starting voltage of its generation satisfies the fluorescent tube needs with regard to difficulty, can produce noise and stroboscopic phenomenon in addition when work, power consumption is big; The package unit complex structure, volume is big, weight is big, should not install.Along with the appearance of electric ballast, replaced original iron inductance ballast and starter, but this body structure of lamp bracket does not become.

It is one that the purpose of this utility model provides a kind of high-efficiency electronic ballast and a lamp socket in order to overcome weak point of the prior art, little, in light weight, the easy installation of volume, and can be lower than under the situation of normal voltage, make the energy-saving fluorescent lamp frame of tube starting work.

Task of the present utility model is finished like this: become on a rectangle metal or the plastic plate, a lamp socket directly links to each other with electric ballast and constitutes Amperite lampholder, Amperite lampholder is made up of an electric ballast and two elastic sheet metals, be installed in the rectangular plastic magazine, respectively there are several louvres the both sides of the long face of rectangular plastic magazine, and being fixed on an end of rectangle lamp bracket base plate, the other end is fixed with a common lamp socket.This energy-saving fluorescent lamp frame is to substitute original Inductive ballast and starter by high-efficiency electronic ballast, with being integral of lamp socket.L in the described high-efficiency electronic ballast is a magnet ring inductance, and the high-frequency oscillation voltage that prevents ballast is provided with the influence of supply line.Diode D ₁～D ₄Form bridge rectifier, with filter capacitor C ₁Be oscillating circuit, 300 volts of DC voltages are provided.R ₁, R ₂Initial start resistance for oscillator; R ₃, R ₄Be the base stage current-limiting resistance; Triode BG ₁, BG ₂Form the oscillator main body with feedback transformer; Feedback transformer is by coil L ₁, L ₂, L ₃Form with magnet ring.D ₅, D ₆Be used for stablizing the clean input voltage of triode, guarantee that the oscillating current of triode is stable.L ₄, C ₅Be the series resonance element, the decision frequency of oscillation, and by C ₅For fluorescent tube provides operating voltage, filament 1～2, filament 3～4 are four leading foots of two filaments.C ₃, C ₄, C ₅Be partiting dc capacitor, C ₂For the triode protecting component can reduce simultaneously the high frequency radiation of circuit, prevent interference to other electric capacity.80 volts of the starting voltages of this high-efficiency electronic ballast, 100～270 volts of the voltage scope of applications, environment temperature accommodation-20 ° C is to+50 ° of C; Starting speed＜1S; Power factor 0.91; 15 watts, 20 watts, 30 watts, 40 watts of power.

The utility model has been compared following remarkable advantage with prior art: the first, owing to adopt above scheme, when supply voltage only was 80 volts, circuit just can provide enough starting voltages to fluorescent tube, makes fluorescent tube light work.The second, because of circuit working at the HF switch state, own loss is little, can improve the luminous efficiency of fluorescent tube, has energy-conserving action, and luminous stable, noiselessness, does not have and dodges frequently fast starting in one second kind, prolonging lamp tube service life.Three, owing to save starter and part annex, with electric ballast and being integral of lamp socket, overall structure is simplified, and can make the novel lamp frame carried type various, and is luxurious attractive in appearance, easy for installation.

Below in conjunction with accompanying drawing the utility model and operation principle are described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Serial number name among the figure;

(1) lamp bracket base plate, (2) Amperite lampholder, (3) louvre, (4) common lamp socket.Shown in accompanying drawing 1,2, this energy-saving fluorescent lamp frame can be according to the length of fluorescent tube, the length of lamp bracket is set, during use, fluorescent tube is contained in the Amperite lampholder (2) and common lamp socket (3) lining at lamp bracket two ends, open power supply, through 220 volts of supply voltages of electric ballast through rectification, after the filtering in capacitor C ₁300 volts of DC voltages of last generation are to by triode BG ₁, BG ₂The push-pull oscillator circuit of forming for core provides operating voltage.At first by 300 volts of voltages through resistance R ₁, R ₂Be BG ₂Provide starting of oscillation voltage and conducting work forms 300 volts of voltages through C ₄, filament 1-2, C ₅, filament 3-4, L ₄, L ₃, BG ₂The series loop of forming is to capacitor C ₅Charging is subsequently because feedback transformer L ₁, L ₂, L ₃The coupling effect, make BG ₂By, BG ₁The beginning conducting.Form capacitor C ₅Through filament 1-2, C ₄, BG ₁, L ₃, L ₄, filament 3-4 discharge, series resonant circuit produces free oscillation, frequency of oscillation is by inductance L ₄, capacitor C ₅Decision, light tube electric voltage is taken from C ₅Two ends.According to voltage parameter, frequency of oscillation is 40KHz, and 1500V can be provided _PPStarting voltage, after the lamp works, inductance L ₄Be used for stablizing the operating current of fluorescent tube.
