Abstract

The utility model relates to a novel power-saving ballast which comprises a starter and a switch for the stater, belonging to an illuminating device of fluorescent lamps. The power-saving ballast is composed of a circuit board which is provided with electric elements, a box and an inductive ballast, and a switch can be also arranged; the circuit of the power-saving ballast is provided with full-wave double voltage and introduces ac ingredient by capacitance; the lowest starting voltage is above 135V, the power conversation can be 10% to 30%, and the cost can be half of a high-frequency ballast. The utility model generates no electromagnetic pollution and noise, and is in particular suitable for the areas where the power is insufficient.

Description

Power saving ballast

The novel energy-conserving ballast belongs to the electric lighting that is used for fluorescent lamp.

The problem that common Inductive ballast exists low-voltage not start.For head it off, developed high frequency ballast in recent years, but its life-span is short, the cost height, and cause the electromagnetism public hazards.Recently Shanxi related factory has produced a kind of multifunctional electronic switch, and the electric capacity half-wave multiplication of voltage that is actually belt switch starts, and the ballast of resistance ballast compares with common Inductive ballast, and brightness only reaches about 70 percent, and electric current is twice.

The purpose of this utility model is to develop such ballast, and its starting resistor is minimum to be reached below the 135V, economize on electricity, and cost is lower than high frequency ballast, and the life-span is long.

The purpose of this utility model is achieved in that designs the all-wave capacitance voltage multiplier circuit to reduce electric current, introduce Alternating Component to drive away the static of light modulation inside pipe wall by little electric capacity, thereby the reduction starting resistor replaces the resistance ballast with Inductive ballast, thereby improves power factor (PF) and economize on electricity.

Test shows, its lowest starting voltage is 120-135V and use common Inductive ballast than more electricity saving 10 to 30, and brightness is basic identical, the no higher-order of oscillation, noiseless.

Below accompanying drawing is elaborated.

Fig. 1, Fig. 2 are the novel energy-conserving ballast circuits.Use integrated full-bridge element or 4 diode D in the circuit ₁To D ₄Compose in parallel full-bridge again by consistent per 2 series connection of polarity, per 2 triode series connection place are for exchanging arm A-A, B-B, and place in parallel is output arm C-C, D-D, 2 capacitor C ₁, C ₂(0.47 to 3.3 microfarad) by B-B(by shown in Figure 1) or B-B connect capacitor C ₅After promptly on B '-B ' (by shown in Figure 2) is connected the formation full-wave voltage multiplier circuit respectively with C-C, D-D; C-C, D-D connect diode D respectively ₅(polarity and D ₁Consistent) to E-E and diode D ₆(polarity and D ₁Consistent) to F-F, capacitor C ₃, C ₄(0.1 to 1 microfarad) connects E-E and A-A and F-F and B-B(D respectively ₅, D ₆, C ₃, C ₄Can omit, but the repeated priming poor performance), D ₅, D ₆Be to prevent C ₃, C ₄Respectively with C ₁, C ₂Short circuit, and C ₃, C ₄Can introduce a small amount of Alternating Component and drive away the static that starts of being unfavorable for that the back of turning off the light gathers on the fluorescent lamp tube wall, can also overcome full direct current simultaneously because electrophoretic action makes half of special bright, the half of black intrinsic defect of fluorescent tube; By exchanging arm A-A connects 1 to 10 microfarad to power input A '-A ' capacitor C ₅(by shown in Figure 1) or by exchanging arm B-B to C ₁, C ₂Mid point meets C ₃(by shown in Figure 2), it plays metering function; These two kinds of circuit are exactly starter circuit, to be " starter " in its box of packing into, one output line connects the light modulation pin again during use, and another output line F-F is the pin (2 pin short circuits of preferably every end) that F '-F ' connects the other end again after meeting Inductive ballast Z; Transfer to former starter, A '-A ', B '-B ' connects power supply and just can use; It is exactly " starting switch " that A '-A ' or B '-B ' connects that K switch packs in the box with start-up circuit, and using method is identical with starter, just many switches; It is " novel energy-conserving ballast " that the arbitrary output line F-F of starter meets Inductive ballast Z, and using method is identical with starter, but does not connect Inductive ballast in addition.In addition, between power line A '-A ' and B '-B ', between output line E-E and the F-F or all can and connect the discharge resistance of 100K-10M on the electric capacity.

Fig. 3 is that the side of Energy-saving ballast is cutd open structure chart.(1) be start-up circuit and Inductive ballast, (2) are the novel energy-conserving ballast boxes.

Fig. 1 circuital current is little, and Fig. 2 circuit cost is low, and performance is identical.
