Abstract
The utility model relates to a power saving voltage regulating and light-regulating fluorescent lamp ballast, which applies semiconductor components which are arranged in a circuit arrangement which can start and control an electric discharge lamp. The utility model is composed of an auto-coupling voltage regulator, a commutation filtering circuit, a high frequency oscillating circuit, a high frequency filter, etc. The purposes of energy conservation, starting at a low voltage, and regulation of the light can be realized by utility model; a starting device can be omitted; the utility model has the advantages of no stroboflash and noiseless, and luminescence efficiency can be improved more than 10%.
Description
The utility model relates to a kind of circuit arrangement of using semiconductor device in discharge lamp igniting or control.
High-frequency electronic ballast now has been applied to fluorescent lamp.Chinese patent GG87217123, CN2061756U, CN2053010U, CN2058548U, CN2067058U etc. all provide a kind of interference little, circuit efficiency and the higher electronic ballast for fluoresent lamp of stability, mainly formed, but can not be realized light modulation by current rectifying and wave filtering circuit, start-up circuit, high-frequency oscillating circuits.
The CNGG87204691 patent application proposes a kind of dimming energy-saving durable fluorescent lamp device, mainly is made up of voltage controller power source, rectifying device, direct current voltage reulation, chokes startup etc., and fluorescent lamp is under the direct current situation works.
The purpose of this utility model be to provide a kind of can light modulation, make the situation of fluorescent lamp operation again in the high-frequency current excitation, needn't use starter, no stroboscopic, muting ballast.
The utility model mainly is made up of automatic coupling voltage regulator, current rectifying and wave filtering circuit, high-frequency oscillating circuits and high-frequency filter circuit etc.
The automatic coupling voltage regulator dividing potential drop can adopt continuous voltage regulating or stepping regulator, i.e. slidingtype or how tapped.
High-frequency oscillating circuits adopts inductive feedback formula oscillator.
The utility model since utilize automatic coupling voltage regulator the pressure regulation effect, change the high frequency pumping electric current, thereby reach energy-conservation and the purpose of adjusting illuminance.In addition, utilize high-frequency current activating fluorescent pipe can obtain low voltage starting, (civil power 80V input can start), needn't use starter, no stroboscopic, noiseless, improve luminous efficiency more than 10%, the loss of circuit itself reaches the purpose of energy saving much smaller than inductance type ballast.Simultaneously, this installation weight is light, and is easy for installation.
Accompanying drawing is a circuit diagram of the present utility model.
Embodiment: as shown in the figure, the automatic coupling voltage regulator T that is located at the current rectifying and wave filtering circuit input is the stepping pressure-adjusting type.The 50Hz electric main through the T dividing potential drop after D
1～D
4Rectification and capacitor C
1Produce the above direct current of 80V after the filtering, pass through BG again
1,
2The inductive feedback formula high-frequency oscillating circuits of forming is transformed into 25～30(KHz) high-frequency current activating fluorescent fluorescent tube H starter and operate as normal, can add the high frequency filter circuit.
