Description

Multi-source fluorescent lamp energy saving switch

The utility model relates to a kind of switch for fluorescent lamp.Particularly electric ballast and switch for fluorescent lamp are combined, in electric ballast, increased the switch for fluorescent lamp of Light modulating device and coupling capacitance.

For a long time, the switch of fluorescent lamp and ballast are divided into two parts, and it is inconvenient that people often feel in use, installation process.At fluorescent lamp with to aspect the utilizing of useless fluorescent tube, people are constantly research and development always also, but does not find a kind of by effective, the good method being convenient to promote that everybody generally acknowledges so far.Chinese patent 91218921.5 discloses a kind of " energy-conservation accent press polish type fluorescent lamp ballast ", this ballast is the purpose that the method that line voltage utilizes autotransformer that supply voltage is reduced is reached light modulation, the method just exists with regard to very low area at line voltage itself and is difficult for build-up of luminance, the unconspicuous shortcoming of light modulation, and adopt autotransformer need consume a large amount of copper materials, its volume is big, heat is also big, the energy that consumes from coupling transformer itself is also bigger, therefore exists cost height, complex structure, the unconspicuous disadvantage of economize on electricity.Chinese patent 91225896.9 discloses a kind of " fluorescent lamp dimming energy-saving ballast ", and this ballast is to utilize the direct voltage multiplying rectifier of civil power, reaches the purpose of light modulation by the mode of serial connection decompression capacitor in circuit.The withstand voltage of this circuit requirement decompression capacitor must be enough big, and it is compared with traditional ballast and has just saved a starter, and it exists line voltage itself is difficult for build-up of luminance with regard to very low area shortcoming equally.Also there is the shortcoming that can not utilize again useless fluorescent tube in aforementioned binomial patent except that above-mentioned defective.

The purpose of this utility model provides a kind of fluorescent lamp energy-saving switch of multiple light courcess, and it not only is combined as a whole switch for fluorescent lamp and electric ballast, and the energy light modulation, and can utilize useless fluorescent tube again.

The purpose of this utility model is achieved in that switch for fluorescent lamp that contains electric ballast of design, and two buttons are installed on switch housing: make mains switch for one, the work of control ballast: make dimmer switch for one, the control lighting tube brightness.In the circuit of electronic ballast of forming by anti-jamming circuit, current rectifying and wave filtering circuit, oscillation inverter circuit, starter ballast circuit, increase light adjusting circuit and coupling capacitance.Light adjusting circuit is by inductance coil L ₁And L ₂, K switch ₂Form.L wherein ₁With L ₂Series connection, K ₂With L ₂In parallel.Coupling capacitance is by C ₈Form.Light adjusting circuit and coupling capacitance are connected in the circuit of starter ballast, and light adjusting circuit is connected with an end of fluorescent tube, and coupling capacitance is in parallel with the other end of fluorescent tube.When turning on the power switch, electric ballast is started working, and civil power behind anti-jamming circuit, is obtained direct voltage by current rectifying and wave filtering circuit.The oscillation inverter circuit converts this direct voltage to high frequency voltage, and this voltage makes normal starter of fluorescent lamp and steady operation behind the circuit of starter ballast.When opening dimmer switch, i.e. K ₂The luminous flux that closure, fluorescent lamp are sent is equivalent to the fluorescent lamp luminosity of 40W, and this moment, the light of lamp strengthened; When closing dimmer switch, i.e. K ₂Disconnect, the luminous flux that fluorescent lamp sends is equivalent to the fluorescent lamp brightness of 20W, and this moment, the light of lamp weakened.Because the existence of coupling capacitance, the open filament of fluorescent lamp one end only needs that fluorescent tube is changed a direction and installs, and just can continue to use, and its illuminance is the same with new fluorescent tube.

The utility model collection starter, ballast, capacitor and switch one reach the light modulation effect by increase light adjusting circuit in circuit; Increase coupling capacitive circuit is realized the utilization again to useless fluorescent tube in circuit.

Adopt such scheme, not only simple in structure, easy to use, cost is low, is not subjected to the influence of line voltage, and the low-voltage starter performance is good, and economize on electricity is significantly, no stroboscopic, and light modulation is obviously strong and weak, and fluorescent tube prolongs useful life.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a shape assumption diagram of the present utility model;

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

Fig. 1 and Fig. 2 also are embodiment of the present utility model.

In the multiple light courcess fluorescent lamp energy-saving that Fig. 1 describes is opened, a shell 1 is arranged, two switches are arranged on shell 1.One is mains switch 2, and another is a dimmer switch 3.One electric ballast is arranged in shell 1.Fig. 2 has described the operation principle of electric ballast.In Fig. 2, ballast circuit is made up of anti-jamming circuit, current rectifying and wave filtering circuit, high frequency, oscillating circuit, starter ballast circuit, light adjusting circuit and coupling capacitance.Wherein anti-jamming circuit is by transformer B ₁And capacitor C ₁Form; Current rectifying and wave filtering circuit is by D ₁, D ₂, D ₃, D ₄, C ₂Form; The oscillation inverter circuit is by Q ₁, Q ₂, R ₂, R ₃, R ₄, R ₅, C ₄, C ₅, B ₂Form; The starter ballast circuit is by L ₁, L ₂, C ₉, C ₁₀Form; Light adjusting circuit is by L ₁, L ₂, K ₂Form; Coupling capacitance is by C ₈Form.L in light adjusting circuit ₁With L ₂Series connection, K ₂With L ₂In parallel.Light adjusting circuit and coupling capacitance series connection back are in the circuit of starter ballast, and light adjusting circuit is connected coupling circuit C with an end of fluorescent tube ₈In parallel with the other end of fluorescent tube.

When pressing mains switch 2, make switch 2 be in " ON " state, electric ballast is started working, with civil power behind anti-jamming circuit, by D ₁～D ₄Rectification, C ₂Filtering forms the direct voltage of about 300V.High-frequency oscillating circuits converts this direct voltage the high frequency voltage of the about 30KHz of frequency to, and this voltage is through L ₁, L ₂, C ₉, C ¹⁰Behind the starter ballast, make normal starter of fluorescent lamp and work.When the needs light modulation, dimmer switch 3 is pulled to " by force " position, the K in the light adjusting circuit ₂Be closed L ₂The luminous flux that short circuit, fluorescent lamp are sent is equivalent to the brightness of 40W, and this moment, light was strong.Dimmer switch 3 is pulled to " weak " position, the K in the light adjusting circuit ₂Be disconnected L ₂Devote oneself to work, the luminous flux that fluorescent lamp sends is equivalent to the brightness of 20W, at this moment dark lighting.When pressing mains switch 2, make switching tube be in " OFF " state, electric ballast quits work.

In the fluorescent lamp use, if a pin of filament opens circuit, fluorescent lamp can be changed a direction again in the place in circuit, useless fluorescent tube is at coupling capacitance C ₈Effect under, normal starter can continue to use, and its illuminance is with newly fluorescent tube is the same.

The utility model can directly be fixed on the wall, also can embed in the body of wall to install.
