Abstract

The utility model relates to a low voltage electronic starter, composed of a relay, a diode, a capacity, a resistance, etc. The utility model is characterized in that a diode D1 with a positive half wave current conveyance but a negative half wave closed, and a capacitor C1 are connected with both ends of the starter, and the starter is connected with a ballast to form a resonance circuit. Therefore, the utility model has the advantages of more low starting voltage, more stable starting performance, simpler structure, more low cost of products, etc., is directly capable of replacing the original starter to use and is an ideal product.

Description

The Low-voltage Electronic starter

The utility model relates to a kind of starter for fluorescent, especially a kind of Low-voltage Electronic starter.

The starter for fluorescent of Shi Yonging all is could normally to use under the situation of voltage 220V usually in the market.And China influences the startup of starter for fluorescent because power tense causes many regional brownouts, and this has just required the low-voltage starter device.It is " electronic starter for fluorescent lamp " of ZL91227267.8 and " the all-round electronic starter of fluorescent lamp " that the patent No. is ZL93213896.9 that Patent Office of the People's Republic of China discloses the patent No., existing starter for fluorescent has been done improvement, starting voltage is corresponding lower, corresponding prolongation in the useful life of fluorescent tube; But weak points such as these two kinds of starters exist complex structure, start the reliability instability, starting voltage is also higher.

The purpose of this utility model will provide a kind of Low-voltage Electronic starter exactly, and its starting resistor is lower, structure is simpler, cost is cheaper, the fluorescent start performance is more stable, can directly replace existing starter to use, greatly prolonging lamp tube useful life.

Technical solution of the present utility model is such; it is by relay; the anti-pressure protection diode D2 of relay, the compositions such as contact protection capacitor C 3, diode D1, capacitor C 1, C2 and resistance R of relay; at M, the N two ends diode D2 of starter contact, capacitor C 2 is connected in parallel and join with the normal-closed end (2.-5.) of relay after resistance R is connected again, also be provided with at M, the N two ends of starter contact simultaneously have only the positive half wave electric current by the diode D1 that bear half-wave and is cut off and capacitor C 1 for being connected in parallel and connecting with formation resonance electrical equipment with ballast.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model Low-voltage Electronic starter structural representation.

Fig. 2 is the utility model Low-voltage Electronic igniter circuitry schematic diagram.

As shown in Figure 1, when power supply during by ballast 4, filament of fluorescent lamp 3, the M that enters starter contact 2, N two ends, supply voltage directly is not added in M, the N two ends of starter contact 2 before fluorescent lamp starts, and resistance R is to capacitor C 2 chargings.When being charged to certain voltage, 2.-4. relay 1 Chang Kaiduan disconnects again.Be higher than the 130-150 volt at supply voltage and disconnect in a flash,, produce a high-voltage pulse, be enough to make lamp tube starting because the existence of capacitor C 1 and diode D1 makes ballast 4 inductance and capacitor C 1 resonance.Behind the lamp tube starting, the voltage that is added in lamp tube ends is lower, and because of effect relay 1 no enough electric current adhesives of resistance R, fluorescent lamp just is in illuminating state always like this.Capacitor C 3 is the contact protection element of relay 1, and diode D2 is the anti-pressure protection element of relay 1.

The utility model is owing to M, the parallel connection of N two ends of starter contact 2 in circuit inserted diode D1 and C1, when relay 1 Chang Kaiduan ((2)-(4)) adhesive, M, N two ends have only all electric currents that just struggles against to pass through, at this moment ballast 4 and capacitor C 1 storage power all, ought brightly open in a flash, the coil of ballast 4 and capacitor C 1 produce resonance and form a high-voltage pulse.So greatly reduce the starting resistor of starter for fluorescent.Make abundance warm-up time of starter, fluorescent lamp can a build-up of luminance, has strengthened the stability that starts, and this is prolonging lamp tube useful life greatly also.

The utility model is only used six electronic components commonly used, makes it simple in structure, product cheap.The design of employing two-wire system is superior to the four-wire system electronic starter that uses in the market, and can directly replace former starter to use, and is a kind of desirable renewal product.
