Description

The fluorescent tube starting device

The utility model relates to a kind of ballast that opens bright fluorescent tube, especially can open the ballast of a bright disconnected end filament florescent lamp pipe.

Traditional fluorescent lamp tube is compared with bulb, with its luminous efficiency height, energy-conservation characteristics and extensive use, and gradually replaces bulb then.But the manufacture process requirement and the cost of fluorescent tube are higher, and in use, and usually an end filament is had no progeny and just can not be used and abandon, and has reduced the useful life of fluorescent tube widely, causes great waste.Therefore, research and development fluorescent tube one end filament is had no progeny and still can be opened bright luminous ballast significant meaning is arranged.More than and the fluorescent tube of a disconnected end filament described below be the not fluorescent tube of gas leakage.At present, Chang Yong fluorescent tube ballast has three kinds: inductance type ballast, electronic ballast and capacitance boost formula ballast.Capacitance boost formula ballast wherein has the Qi Liang advantage of filament breaking fluorescent tube, supplying with lamp tube current because of this ballast mainly gives by electric capacity, magnitude of current deficiency, so, exist the substandard brightness of brightness of the bright fluorescent tube that opens, and the fluorescent tube two ends that make easily blackouts, the fluorescent tube fast weak point that wears out, therefore, people seldom use it.

The purpose of this utility model provides a kind of fluorescent tube starting device, and it combines with existing fluorescent tube ballast, should be able to open the bright end fluorescent tube of filament breaking, and can reach normal brightness, the life-span that prolonging lamp tube is used.

The utility model comprises two inputs that connect ballast output, two outputs that connect a disconnected end filament florescent lamp pipe, and the bridge rectifier that constitutes by diode, described two inputs are connected with the input of bridge rectifier, it is characterized in that: between described two input one ends and described bridge rectifier two outputs, each also is connected to electric capacity and resistance; The corresponding diode that respectively is serially connected with between described bridge rectifier output and described two outputs; Between described two input other ends and described two outputs, also each and be connected to electric capacity and resistance.

The fluorescent tube starting device of said structure, the alternating current that ballast is defeated by carries out rectification by bridge rectifier, and directly flows to the fluorescent tube of a disconnected end filament, and the electric current abundance provides the enough energy for making fluorescent tube can send standard light.Simultaneously, but all be provided with the electric capacity of booster tension, the voltage max of positive and negative half-wave gathered into folds to reach 900 volts high pressure, be added in the two ends of fluorescent tube, be enough to the noble gas body in the breakdown fluorescent lamp pipe, open bright fluorescent tube at input and output side; Fluorescent tube opens bright back by former ballast step-down and to keep issue of bidding documents quasi-optical.Like this,, can continue to use a disconnected end filament and gastight fluorescent tube, prolong its useful life, thereby achieve the goal with ballast.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be circuit theory diagrams of the present utility model.

Shown in Figure 2, be that the utility model cooperates the wiring schematic diagram that opens bright glimmering fluorescent tube with inductance type ballast.

Shown in Figure 3, be that the utility model cooperates the winding diagram that opens bright fluorescent tube with electronic ballast.

In Fig. 1 as can be known, input A with by diode D ₁～D ₄Input, the diode D of the bridge rectifier that constitutes ₁And D ₂Intersection point connect; One output of input A and bridge rectifier, diode D ₁And D ₃Intersection point between, and be connected to capacitor C ₁And resistance R ₁And with another output, the diode D of bridge rectifier ₂And D ₄Interface point between, and be connected to capacitor C ₂And resistance R ₂Diode D ₅Negative pole meet diode D ₁And D ₃Interface point, its positive pole meets output D.Diode D ₆Positive pole meet diode D ₂And D ₄Interface point, its negative pole meets output C.Between input B and the output D, and be connected to capacitor C ₃And resistance R ₃And between the output C, and be connected to capacitor C ₄And resistance R ₄Each electric capacity in the circuit mainly works the effect of boosting, and each resistance is the discharge resistance of corresponding capacitance, and each diode is rectifying tube.The output that the input A of circuit, B connect ballast, output C, D connect the two end electrodes of fluorescent tube.The operation principle of this circuit is: when ballast is defeated by the positive half cycle of alternating current, and diode D ₂, D ₃, D ₅And D ₆Conducting, alternating voltage are given and are held C ₁And C ₄Charging, charging voltage is the maximum of alternating voltage; When the negative half period of alternating current, diode D ₁, D ₄, D ₅And D ₆Conducting, and give capacitor C ₂, C ₃Charging, charging voltage also is the maximum of alternating voltage, like this, each capacitor C ₁～C ₄Voltage stack up, obtain about 900 volts high pressure at output C, D, add the disconnected fluorescent tube two ends of filament at one end, enough puncture inert gas wherein, this fluorescent tube of Qi Liang.And the electric current of this circuit is to export after fluorescent tube directly is defeated by in rectification from ballast, so, there are enough electric currents to make fluorescent tube send standard light.Described standard light, be ballast under standard state, open bright standard state, promptly intact fluorescent tube, the normal brightness that is sent.Certainly, this standard should be a national standard.

Among Fig. 2, inductance type ballast 1 is combined into a new ballast by the lead connection with this fluorescent tube starting device 2, open bright fluorescent tube 3, and reach by a change over switch K and to use the disconnected fluorescent tube of filament and the purpose of same fluorescent tube of an end filament.Ballast 1 is generally inductance type town or electric ballast, when being inductance type ballast, then uses starter 4; When being electric ballast, then remove starter 4, mode of connection such as Fig. 3.Among Fig. 2, when open bright fluorescent tube 3 was standard pipe, K switch was connected output terminals A, B and the fluorescent tube 3 two ends pins of Inductive ballast 1, is the wiring of standard.If an end filament of fluorescent tube 3 has broken, opened not bright fluorescent tube 1 by Inductive ballast 1 separately, at this moment, K switch is dialled output terminals A, B from ballast 1, and meet output C, the D of starting device 2, be the input of the output termination starting device 2 of ballast 1, the output termination fluorescent tube 3 of starting device 2, starter 4 is inoperative.Like this, by starting device 2, it is bright that the fluorescent tube 3 of an end filament is opened, fluorescent tube 3 open bright after, ballast 1 plays the step-down effect, fluorescent tube 3 keeps sending standard light.

In Fig. 3, electronic ballast 5 connects by lead and this starting device 2 also is combined into a new ballast, opens bright fluorescent tube 3.General electric ballast 5 all has two inputs and four outputs, works as K switch ₁And K ₂During contact shown in solid line, for opening the wiring of bright standard fluorescent tube, promptly electric ballast 5 opens bright standard fluorescent tube 3 separately.When the disconnected end filament of fluorescent tube 3, ballast 5 can not open separately when bright, with K switch ₁And K ₂When stirring contact shown in dotted line, fill device 5 by electronics and cooperate the fluorescent tube 3 that opens a bright disconnected end filament with starting device 2.Resistance R ₆, R ₇With the output of ballast 5 and connect, make ballast 5 that stable vibration output be arranged respectively, open bright fluorescent tube 3 for starting device 2 power supplies.In like manner, fluorescent tube 3 open bright after, ballast 5 plays the step-down effect, fluorescent tube 3 still can send standard light.
