Description
Affiliated technical field:
The utility model relates to a kind of ballast, relates in particular to a kind of energy-saving fluorescent lamp ballast.
Background technology:
The fluorescent lamp tube ballast of Shi Yonging generally adopts electric ballast in the market, has high frequency and pollutes, and have harmonic problem, thereby fluorescent tube is shorter useful life.
Summary of the invention:
The purpose of this utility model is to provide a kind of and lights fast and do not have harmonic problem, anti-interference strong energy-saving fluorescent lamp ballast.
The purpose of this utility model is achieved in that described energy-saving fluorescent lamp ballast, comprises filament one end of inductance coil and fluorescent tube, the filament other end of fluorescent tube, and its design feature is gone into filament one end of fluorescent tube for outer interchange power supply one termination; The outer interchange power supply other end is connected with inductance coil behind the loop via resistance and electric capacity composition, inserts the filament other end of fluorescent tube again; One controllable silicon two ends are connected on respectively on filament one end and the filament other end of fluorescent tube; Second electric capacity be connected on respectively between filament one end and the filament other end of fluorescent tube after second resistance is connected in series; Be connected on respectively between filament one end and the filament other end of fluorescent tube after diode and the 3rd resistance serial connection, the 3rd resistance also connects the 3rd electric capacity; Between the node of the silicon controlled control utmost point and second electric capacity and second resistance, be connected with trigger tube.
The utlity model has following characteristics: 1) ballast is lighted with the 50Hz frequency, and no harmonic problem is anti-interference strong; 2) have the low-voltage starter function, need not jump the bubble starter; 3) have filament pre-heating starter and two kinds of forms of non-filament pre-heating starter fluorescent tube; 4) at the bottom of the cost, circuit is simple, and is safe and reliable, long service life; 5) gathered the advantage of electric ballast and Inductive ballast.
Description of drawings:
Fig. 1 is a circuit diagram of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples structure of the present utility model and operation principle and the course of work are elaborated:
As shown in Figure 1, the utility model comprises the filament one end A of inductance coil L and fluorescent tube, the other end B of fluorescent tube, and its design feature is gone into the filament one end A of fluorescent tube for outer interchange power supply one termination; The outer interchange power supply other end is connected with inductance coil L behind the loop via resistance R 1 and capacitor C 1 composition, inserts the filament other end B of fluorescent tube again; One controllable silicon VS two ends are connected on respectively on the filament one end A and other end B of fluorescent tube; Second capacitor C 2 be connected on respectively between the filament one end A and filament other end B of fluorescent tube after second resistance R 2 is connected in series; Be connected on respectively between the filament one end A and filament other end B of fluorescent tube after diode VD2 and the 3rd resistance R 3 serial connections, the 3rd resistance R 3 also connects the 3rd capacitor C 3; Between the node of the control utmost point of controllable silicon VS and second capacitor C 2 and second resistance R 2, be connected with trigger tube VD1.
Power supply adopts 220 volts of alternating currents, operation principle: when the power supply positive half cycle current gives capacitor C 1 charging, behind the inductance L ballast, charge diode VD2 conducting, capacitor C 2 chargings to capacitor C 3, because it is little that resistance R 2 resistances flow through electric current greatly, when the both end voltage rising of capacitor C 2 charging back, make trigger tube VD1 conducting, because of trigger tube and the SCR control utmost point join, at this moment controllable silicon VS conducting, electric current flow back into power supply by controllable silicon.
When power supply is negative half period, not conducting of diode VD2, capacitor C 2 does not have electric current to pass through, and trigger tube VD1 does not work, and the controllable silicon VS control utmost point does not have electric current, and controllable silicon VS is turn-offed rapidly; At this moment because capacitor C 1 is connected with inductance L, and lamp tube ends A, B produce high pressure lights fluorescent tube, and resistance R 1 and R3 play the capacitor discharge effect, fluorescent tube is lighted the back and is provided normal operating current of fluorescent tube and voltage by capacitor C 1 and inductance L series circuit.
