Description

Energy-saving electronic ballast

The utility model relates to a kind of electric ballast technical field that starts fluorescent lamp.

What traditional fluorescent lamp ballast adopted is the coil type ballast of copper core, silicon steel chip, the ballast of this structure in use be unable to do without starter, and starter very easily burns out, and causes ballast to work, this in addition ballast also has complex structure, consume material is many, cost height, product heaviness, start-up time is long, consume electric power is many, and fluorescent tube is short useful life, and the fluorescent tube that burns out can not recover a series of defectives such as use.

The purpose of this utility model is a kind of novel electron ballast that overcomes above-mentioned defective of design.This electric ballast has simple in structure, and consumptive material is few, and is in light weight, do not need starter just can start, and cost is low, and start-up time is short, little power consumption, and fluorescent tube long service life, the fluorescent tube that burns out also can recover many advantages such as use.

Energy-saving electronic ballast of the present utility model is made up of housing, ballast circuit, power supply wiring, fluorescent tube wiring four parts.Ballast circuit is fixed in the housing, and the power supply wiring and the fluorescent tube wiring of drawing through ballast circuit extend to outside the housing in housing.Ballast circuit is to be parallel with two circuits between two power supply wirings, is parallel with two capacitor C1, C2 and a resistance R 1 on the circuit earlier, after be in series with a diode D2; Be parallel with two capacitor C3, C4 and a diode D1 on another circuit earlier, after be in series with a resistance R 2, C1, C2 in parallel, R1 draw a fluorescent tube wiring between the D2 circuit of series connection, draw another fluorescent tube wiring at C3, C4, the D1 of parallel connection between the R2 circuit of series connection.Diode D1, D2 in the ballasting circuit mainly plays burning voltage, restriction electric current, and capacitor C1, C2, C3, C4 mainly play voltage stabilizing, discharge high pressure.Burn out the electric elements in the ballast circuit in order to prevent mains voltage variations, in the circuit of power supply wiring, be provided with line protector.During use, will draw two fluorescent tube wiring and link to each other (as shown in Figure 2) with the filament at fluorescent tube two ends from ballast circuit, power supply wiring links to each other with power supply.The connection of this electric ballast is different fully with traditional connection, when power connection, ballast circuit just produces high pressure and puts fluorescent lamp on the filament at fluorescent tube two ends, both having made is that filament is burnt out, adopts this energy-saving electronic ballast still can make this fluorescent tube recover to use.

This novel electronic ballast has following advantage: (1) economize on electricity, the power factor of traditional ballast inductive load is low, the electric current of transmission line is increased and the pressure drop increase, again owing to iron core in the coil produces eddy current, thereby bring the very big loss of electric energy, the utility model has then overcome above-mentioned defective, has energy-conservation function; (2) but can make useless fluorescent tube resume combustion the useful life of prolonging lamp tube.Because traditional coil ballast in use will produce the induced voltage that is several times as much as normal voltage, filament is under so high voltge surge, its useful life only about 2000 hours then, as long as then its loop open circuit is blown in the somewhere of filament, this fluorescent tube just can not use and become useless pipe.And the closed-loop path is adopted in wiring of the present utility model, and no matter burn at which place of filament, and whole loop is closed, in use still can be luminous, so this electric ballast can obviously prolong the useful life of its fluorescent tube; (3) start soon, volume is little, and is in light weight, advantages such as raw material province.Traditional fluorescent start time needs 5-15 second, and only be 1 second the start-up time of fluorescent tube behind this novel electronic ballast and adopt.Weight and volume only is about 1/10～2/10 of traditional ballast, can save raw material significantly.

Accompanying drawing 1 is the ballast circuit schematic diagram of the utility model energy-saving electronic ballast.

Accompanying drawing 2 is the syndeton schematic diagram of energy-saving electronic ballast and fluorescent tube.

Fig. 1, Fig. 2 can be used as embodiment schematic diagram of the present utility model.1 line protector; 2 power supply wirings; 3 fluorescent tube wiring; 4 housings; 5 ballast circuits.Line protector (1) is 1 peace fuse, and C1 and C3 are 400V92.9,1.5 μ F ± 10%; C2 and C4 are 250MEF, 1-J2.2J; R1 and R2 are 820K Ω; D1 and D2 are IN4007.
