Abstract

The utility model relates to an instantaneous electronic ballast which can provide an instantaneous starting lamp tube. The utility model comprises that a rectification circuit is connected between a radio frequency interference filter circuit and a frequency generating circuit. The frequency generating circuit can generate about 24KHz trigger signal to drive a switching circuit which is connected with the output end of the frequency generating circuit. The switching circuit can cause the direct current voltage to be switched to the 24KHz frequency signal, and the high voltage signal is output by the filter circuit which is connected to the output end of the switching circuit to light the lamp tube. The utility model is characterized in that the lamp tube can be started instantly, and no starter does not need.

Description

110 volts and 220 volts of Momentary electronic ballasts

The utility model is a kind of Momentary electronic ballast of lighting fluorescent tube.The ballast of ripe usefulness needs by starter when lighting a lamp, and just can make fluorescent tube bright fully after dodging several times, and scintillation is arranged, and makes end user's eyes for a long time under this environment, is easy to fatigue, and the electric energy of Xiao Haoing is also more in addition, causes energy waste.

In view of this, in order to solve the aforementioned problems in the prior, the applicant is according to the experience and the hammer away of accumulation for many years, provide a kind of, 110 volts and 220 volts of Momentary electronic ballasts, it does not need starter and does not need the scintillation time of several seconds when lighting a lamp, and can one opens promptly bright, saves energy.

The ballast that the utility model provides is to realize like this, a kind of Momentary electronic ballast that the transient starting fluorescent tube can be provided of the present utility model, comprise: a rectification circuit is connected between a radio frequency interference filter circuit and the frequency generating circuit, this frequency generating circuit produces the triggering signal about 24KHZ, be connected the commutation circuit of frequency generating circuit output with driving, this commutation circuit switches to direct voltage the frequency signal of 24KHZ, by the filter circuit that is connected to the commutation circuit output this high-voltage signal is exported, to light fluorescent tube.

The purpose of this utility model, characteristics and advantage will be described in detail as follows in conjunction with the embodiments with reference to the accompanying drawings:

Brief Description Of Drawings:

Fig. 1 is a 110V Momentary electronic ballast block diagram of the present utility model;

Fig. 2 is a 220V high power Momentary electronic ballast block diagram of the present utility model;

Fig. 3 is a 110V Momentary electronic ballast structure chart of the present utility model;

Fig. 4 is a 220V high power Momentary electronic ballast structure chart of the present utility model.

Please refer to Fig. 1, it is a ballast block diagram of the present utility model, its left is that the voltage of general chamber electricity (110V) input is through radio frequency interference (RFI) filter circuit (11), surging is removed after full-wave rectifier (12), being rectified into direct voltage supply commutation circuit (13) thereafter uses, provide basic pulse triggering signal source to drive aforesaid commutation circuit (13) in addition and by frequency generating circuit (14), direct voltage is switched to the frequency signal of 24KHZ, produce high pressure by output filter circuit (15) again and light fluorescent tube.

Please refer to Fig. 2, it is a 220V high power Momentary electronic ballast block diagram of the present utility model, and is wherein most of identical with 110V Momentary electronic ballast structure, only partly uses bridge rectifier instead at rectifier, and all the other structures are just the same.

Please refer to Fig. 3, it is a 110V Momentary electronic ballast structure chart of the present utility model, wherein by radio frequency interference (RFI) filter circuit (11) and full-wave rectifier (12), frequency generating circuit (14), commutation circuit (13) and output filter circuit (15) constitute, and at last the high-voltage signal that produces are delivered to fluorescent tube partial circuit (16) and light fluorescent tube.

Radio frequency interference (RFI) filter circuit (11) is made up of C1 and L1, to remove radio frequency interference and the surging in the AC power, utilize full-wave rectifying circuit (12) again, it is that direct voltage is supplied with and given frequency generating circuit (14) and commutation circuit (13) by will the fluctuate voltage commutation of (ripple) of D1, D2 and C2, C3; Be provided through D3 or DIAC by R1 and C4 the triggering opportunity of frequency generating circuit (14), and utilize L2, C5, L3, C6 produces the triggering signal about 24KHZ, promote the Q1 of commutation circuit (13) and Q2 to improve its power factor (PF) and efficient, at last via the L5 in the filter circuit (15), L6 choking-winding to fluorescent tube.

Please refer to Fig. 4 its for the structure chart of 220V high power Momentary electronic ballast of the present utility model, its structure is most of identical with 110V Momentary electronic ballast, rectifying part only, adopt bridge rectifier, to strengthen its fail safe, in addition, be provided through D5 or DIAC by R1 and C4 the triggering opportunity of frequency generating circuit (14).

The ballast that the utility model provides is traditional for high because of switching frequency, so do not have scintillation in using; Therefore efficient is high and highly stable, and it does not need starter, so do not maintain the trouble of changing starter, in the epoch of current environmental protection, makes the utility model have more meaning.Quite convenient with existing light fixture this device that changes the outfit in addition, do not need wiring, so easy construction, the utility model adopts plastic shell waterproof, leakproof, easy to use and power saving.

By as can be known aforementioned, the device that the utility model provides has positive effect in practicality, and not only assembling is easy, and power saving, stablizes and does not glimmer, and meets environmental protection requirement.
