Abstract

The utility model relates to an energy-saving high-effect ballast for fluorescent lamp, comprising a casing, iron cores which are installed in the casing, windings, a capacitor and a resistor. The front ends of primary windings L < 1 >, L < 1 > ' which are wound on the iron cores t, t' are respectively connected with an input end; the terminals are respectively connected with the connection end in parallel of a rc and the front end of secondary windings L < 2 >, L < 2 > '; the ends of secondary windings L < 2 >, L < 2 > ' are respectively connected with the two ends of a fluorescent lamp tube; the energy-saving high-effect ballast for fluorescent lamp can be used for synchronously starting a fluorescent lamp with a power supply switch. The utility model has the advantages that circuit is simple and cost is low; When voltage is low and voltage fluctuation is strong, the fluorescent lamp can not go out after started owing to the voltage fluctuation; electrical energy is saved 30%; universality performance is strong; flickering phenomenon does not happen; the two iron cores can be respectively installed and can also be installed together; matching and installation is flexible and convenient.

Description

Energy-saving high-effect ballast for fluorescent lamp

The utility model relates to a kind of ballast, the efficient energy-saving fluorescent lamp ballast.

Existing commercially available and commonly used ballast.Must could glow starting fluorescent lamp, and the starter life-span is short by starter, in short-circuit condition, just quicken exhausting of filament cathode emitting material and make fluorescent tube shorten (being fluorescent lamp Guan Erduan blackout) useful life when damaging.Fluorescent lamp can extinguish during voltage fluctuation, and starter also can't glow starting fluorescent lamp during to certain value when voltage is low, and versatility is poor, and the fluorescent lamp of different capacity will dispose corresponding ballast.The value of fluorescent tube is low, just can't glow starting fluorescent lamp as end filament open circuit, and power factor is low, and a 8W fluorescent lamp has only 0.36.Electric ballast exists also that the fluorescent tube value is low, easily blackout and anti-load capacity are poor for fluorescent tube two ends, and how fragile electronic original part is, the drawback that the complex process cost is high.

The patent No. 882145126 " the quick starting characteristic ballast of low pressure " though can solve above-mentioned various drawbacks, also exists stroboscopic slowly, can't use in the corner with the fluorescent lamp of this ballast and locate, and is not easy to install.

The purpose of this utility model is to provide a kind of efficient energy-saving fluorescent lamp ballast, and its cost simple in structure is low, highly versatile, stable performance, without starter just can with the synchronous glow starting fluorescent lamp of mains switch, economize on electricity 30% can be matched in various occasions and use no stroboscopic phenomenon.

The utility model is achieved in that by housing and the iron core, winding, electric capacity, the resistance that are installed in the housing to be formed, the elementary winding L on iron core T, the T ' ₁, L ₁' head end connect input respectively, terminal parallel connected end and the secondary winding L that meets RC respectively ₂, L ₂' head end, secondary winding L ₂, L ₂' end connect the two ends of fluorescent tube respectively.

Accompanying drawing: structural representation of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

C is a polarity free capacitor 2-6 microfarad/400 volts, and R is 1/8 watt 220 kilo-ohms, L ₁, L ₂Parameter and L ₁', L ₂' parameter is identical, during operate as normal, and L ₁And L ₂Total voltage at 110 volts, L ₁, L ₁' elementary winding voltage lies prostrate L at 20-30 ₂, L ₂' secondary winding voltage lies prostrate at 60-90.

When circuit is connected mains supply, by L ₁, C, L ₁' constitute ac circuit, at L ₁, L ₁Produce voltage on the ' winding, simultaneously at L ₂, L ₂Also produce voltage on the ' winding and on the electric capacity, three voltage superpositions become a high pressure, and instantaneous high pressure is just lighted fluorescent tube, and the fluorescent tube after lighting is low resistive state.Electric current divides L ₁→ RC → L ₁', L ₁→ L ₂→ fluorescent lamp → L ₂' → L ₁', L ₂→ fluorescent lamp → L ₂Three loop works of ' → RC, when supply voltage descends and during fluctuation, inductance and electric capacity are just made corresponding compensation, and resistance R is connected in parallel on electric capacity two ends and just can prevents the voltage fluctuation of electric capacity two ends and optical flare slowly occur.

The utility model compared with prior art, without starter just can with the synchronous build-up of luminance fluorescent lamp of power switch, and can be in the time of 160 volts just can normal glow starting fluorescent lamp, still do not extinguish saves energy 30% about 80 volts. Highly versatile, 4-12 watt, but the ballast of the 15-40 watt of two kinds of specifications various special-shaped fluorescent-lamp tube in the various power brackets of adapted just, anti-load capacity is strong, and circuit is simple, and cost is low. As long as fluorescent tube possesses electronics and the ion that produces sufficient amount, even the filament of an end or two ends is all opened a way, also can as usual use, prolonged the service life of fluorescent lamp. Stable performance in low-voltage, when voltage pulsation is big, can not extinguished because of voltage pulsation behind the daylight lamp glow starting. Now along with the raising of living standards of the people, family all is particular about beautiful decoration and fluorescent lamp is installed on four jiaos of wall, and original ballast volume is not easy to more greatly paste the angle installation, existing two to be wound with its volume of iron core T, T ' of winding little, symmetry is contained in two sides of daylight lamp holder respectively, be convenient to the supporting various occasions uses that are installed in, also two iron cores can be bolted together becomes whole a use, flexible and convenient to use.
