Abstract

The utility model relates to a self-starting energy-saving ballast for a daylight lamp, which is composed of an iron core, a duplex winding and a capacitor. Because traditional ballasts can only start daylight lamps when the traditional ballasts are matched with starters, common faults of incapability of lighting the daylight lamp due to the starter failure exists in the traditional ballasts. The utility model utilizes the equivalent reactance of a duplex winding reactor and the resonance function of the capacitor C to enable the daylight lamp to automatically start without adding starters in that the coupled relation can generate stable and enough starting high voltage on both ends of the daylight lamp tube when the voltage is within 150V-240V. The starting high voltage is lower than the instant ballistic high voltage of the original starter and the operating current is smaller. The utility model can effectively protect the lamp tube and prolong service life.

Description

Self-starting energy-saving ballast

The utility model relate to a kind of produce and life in illuminating fluorescent lamp automatic starting formula Energy-saving ballast.

Common fluorescent lamp must be furnished with ballast and starter can use, and has obvious disadvantages such as low-voltage, low temperature are difficult for starter, starter is fragile need change, and oneself power consumption is big, and power factor (PF) is low.

The purpose of this utility model is to overcome above-mentioned disadvantage, designs a kind of market town stream and starter function in the automatic starting formula Energy-saving ballast of one.

Fig. 1 is a structure division profile of the present utility model.1, shell (connecting firm banking); 2, iron core; 3, double wrap line group; 4, plastic stent; 5, electric capacity; 6, draw 4 at the end of a thread, on plastic stent, be wound with two groups of enameled wire loops respectively, one group of coil two termination lead-out wire head, another group coil one termination is drawn the end of a thread, connect behind the one end polyphone electric capacity and draw the end of a thread, iron core contains coil from upper and lower insertion respectively, and shell surrounds (connecting base) and forms the utility model integral body.

Fig. 2 is a schematic circuit of the present utility model.

Fig. 2 dotted line is outward a fluorescent lamp, is automatic starting formula Energy-saving ballast schematic diagram in the dotted line: coil n ₁Phase-connecting wire after the right-hand member serial connection K switch; Left end meets fluorescent lamp the left-hand side pin, coil n ₂Lead-out wire behind the right-hand member series capacitance C is connected with the right-hand member lamp pin, another pin connecting to neutral line; Coil n ₂Left end connects another pin of the fluorescent tube the left-hand side.Become a complete automatic starting formula Energy-saving ballast schematic diagram like this.

Advantage of the present utility model is as follows:

1, has the automatic starting function, thereby do not need to add starter in addition, eliminated former starter for fluorescent inefficacy and caused the fault that to light.

2, can disposable glow starting fluorescent lamp during supply voltage lower (more than the 150V).

Can keep fluorescent tube not extinguish when 3, voltage low (more than the 100V) is kept in work.

4, the starter high pressure is suitable, be lower than former starter moment impact high pressure, and operating current is little, thereby can effectively protects fluorescent tube, prolonging lamp tube useful life.

5, little from wasted work, than the daylight lamp energy-saving of former use inductance type ballast more than 10%.

6, power factor (PF) height is little to big mains supply influence.

7, the fluorescent tube luminous flux is higher than general electric ballast.

8, stable and reliable for performance, not fragile.

Operation principle of the present utility model is as follows:

After connecting K switch, coil n ₁, n ₂Form double winding ballast reactor B.Its main winding n ₁Be serially connected with between power supply and the fluorescent tube, be used for chokes; And pair winding n ₂With the two ends that are connected to fluorescent tube SL after capacitor C is connected in series.It has utilized the equivalent reactance of double winding reactor and the resonance effect of capacitor C dexterously, by coupled relation, during to 240V, all can produce stable and enough starter high pressure at the fluorescent tube two ends at voltage 150V, make the automatic starter of fluorescent lamp.After fluorescent lamp is lighted,, reduced the electric current of drawing from electrical network because the capacitor loop electric current has significantly reduced electric current in the choke by the mutual inductance effect, improved power factor (PF), but can increase the electric current in the fluorescent tube, improve the brightness of fluorescent tube, have remarkable energy saving effect.

Enforcement of the present utility model is as follows: coil n with enamelled wire on plastic stent 4 ₁, n ₂

Silicon steel sheet is respectively from being seated into iron core 2 up and down, shell on the cover (connecting base) 1.Behind the paint-dipping drying, coil n ₁Two ends are welded respectively and are drawn the end of a thread 6 ₃, 6 ₄Coil n ₂One end serial connection electric capacity connects lead-out wire 6 later on ₂One end welding lead-out wire 6 ₁, the utility model.Base is fastened on the daylight lamp housing, draws the end of a thread, connect fluorescent tube SL K switch and phase line H as Fig. 2, zero line L can use.
