Abstract
The utility model discloses a capacitive ballast for fluorescent lamps. The utility model is composed of a ballast circuit which is in series connection with a fluorescent lamp, and a starting circuit which is in parallel connection with the fluorescent lamp. The utility model is characterized in that the functions of current limiting and the ballasting are acted by the capacitance, and thus, the inductance in the ballast can be designed into very small. Therefore, the utility model has the advantages that the weight can be lightened, the working circuit can be made stable, and the phenomenon of damage is not easy to happen.
Description
The utility model belongs to the circuit arrangement that is used for discharge lamp igniting or control, especially relates to the condenser type fluorescent lamp ballast.
Fluorescent lamp ballast production is existing historical for many years, the great majority fluorescent lamp ballast of usefulness on the market generally are to adopt bigger coil to produce the effect that inductance reaches current limliting and ballast, make that the voltage that is added on the fluorescent lamp can be too not high behind the fluorescent lamp of start-up point, and the startup stage can produce bigger high-frequency current and make fluorescent lamp light, the shortcoming of this ballast is that volume is big, energy consumption is big, the voltage narrow application range.Though some new fluorescent lamp ballasts are also arranged on the market, most complex circuit, cost height at present.
The purpose of this utility model is: by a kind of condenser type fluorescent lamp ballast of being made up of electric capacity, inductance is provided, make the ballast operating voltage range enlarge, volume reduces, and energy consumption reduces.
Technical scheme that the utility model adopts is: the condenser type fluorescent lamp ballast is formed by the ballasting circuit that is connected in series with fluorescent lamp and with the start-up circuit that fluorescent lamp is connected in parallel.
Advantage of the present utility model is: 1. play current limliting, ballast effect owing to be connected with electric capacity in circuit, can normally use in the time of therefore can making suitable voltage range increase between 160～240V.2. owing to be connected with electric capacity in the circuit, make operating circuit stable, fluorescent lamp increase in useful life and not fragile.3. because adopted electric capacity to play metering function, so the inductance coil volume can reduce a lot, so the utility model volume is little, energy consumption is low, and is in light weight, easy for installation.
Be specific embodiment of the utility model below:
Accompanying drawing 1 is the utility model work block diagram
Accompanying drawing 2 is the utility model circuit theory diagrams
Shown in Figure 2 as Fig. 1, electric power outputting current arrives fluorescent lamp by ballasting circuit, because fluorescent lamp is connected in parallel to start-up circuit, under the effect of start-up circuit, ballasting circuit produces high-frequency current and lights fluorescent lamp, and start-up circuit is in off position subsequently, and the fluorescent lamp conducting.Ballasting circuit is by capacitor C in foregoing circuit
1, inductance L
1, resistance R
1The series connection back links to each other with an end of fluorescent lamp, and the other end of fluorescent lamp and resistance R
2Link to each other and to be formed; And start-up circuit is by capacitor C
2In parallel with relay J, back one terminating resistor R in parallel
3, the D point of another termination rectification circuit, and the C point in another termination rectification circuit of resistance R 3,2 of the A of rectification circuit, B link to each other with the two ends of fluorescent lamp respectively, the contact J of relay J
1-1The two ends of two ends connection fluorescent lamp are formed.
Its operation principle is: behind the power supply input current, and capacitor C
1Play metering function, inductance L
1, resistance R
1, R
2Play the ballast effect, electric current is by rectification circuit, through resistance R then
3Back and capacitor C
2Be connected with relay J, make capacitor C
2Charging, and make relay contact J
1-1Adhesive, in this case, filament of fluorescent lamp begins heating, and this moment is because J
1-1So the short circuit of adhesive start-up circuit is capacitor C
2Begin discharge, but therefore holding contact J still
1-1Adhesive a period of time, treat capacitor C
2Behind the discharge off, J
1-1The contact is decontroled, at this moment inductance L
1Electric current is undergone mutation, and produces self-induced e.m.f, promptly produces high-frequency current the fluorescent lamp conducting is lighted.Because so fluorescent lamp conducting start-up circuit is in off position substantially.
When fluorescent lamp was used 20W, the parameter of ballast was as follows: capacitor C in the foregoing circuit
1=6uF, capacitor C
2=3300uF, inductance L
1=0.08H, resistance R
1=18 Ω, resistance R
2=10 Ω, resistance R
3=2K Ω, diode D
1, D
2, D
3, D
4=2CZ1, relay is selected JZC-22F for use.
When fluorescent lamp was used 30W, the parameter of ballast was as follows:
Capacitor C
1=7uF capacitor C
2=3300uF
Inductance L
1=0.09H resistance R
1=20 Ω, resistance R 2=12 Ω, resistance R 3=2K Ω
