Description
The utility model relates to a kind of application semiconductor device in discharge lamp igniting or control and in order to obtain required output, is used to control the circuit arrangement of reactor.
High-frequency electronic ballast now has been applied to fluorescent lamp.Chinese patent GG 87217123, CN 2061766U, CN 2053010U, CN 2058548U, CN 2067058U 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.
No. 87204691 patent applications of CN GG propose a kind of dimming energy-saving durable fluorescent lamp device, mainly are 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.
No. 88202953 patent applications of CNGG disclose a kind of fluorescence lamp electronic dimmer, it is made up of controller and ballast two parts, controller is by high-frequency filter circuit, current rectifying and wave filtering circuit, DC control supply, control circuit, turnable pulse width frequency converter and decide pulsewidth frequency converter etc. and form, fluorescent lamp is carried out brightness regulation and control, and its structure is comparatively complicated.
The purpose of this utility model is to provide a kind of needn't use starter, can low voltage starting, and no stroboscopic, noiseless, and the energy-conservation magnetic control light adjusting type fluorescent lamp ballast that can regulate illumination.
The utility model mainly comprises current rectifying and wave filtering circuit, high-frequency oscillating circuits and magnetic saturation type dimmer etc.
Can adopt full-wave rectifying circuit and inductive feedback formula high-frequency generator.
The magnetic saturation type dimmer can utilize externally-applied magnetic field (permanent-magnetic field or electromagnetic field) to control the magnetic saturation time of this driver transformer, reaches the control to frequency of oscillation, and then the size of control high-frequency current, makes the illumination of fluorescent tube reach adjustable purpose.Can adopt permanent magnet or electromagnet by the additional magnetic field generation device of driver transformer in the practicality.Usually adopt permanent magnet to be advisable.Regulate the distance of permanent magnet and driver transformer, can realize the purpose of above-mentioned adjusting brightness of fluorescent lamp.
The utility model not only has all advantages of general electric ballast, low-voltage starter, and civil power 80V input can start, needn't use starter, noiseless, no stroboscopic, and, owing to utilize the magnetic saturation time of externally-applied magnetic field device control driver transformer, reach control, realize the purpose of light modulation frequency of oscillation, simple in structure, regulate easyly, power savings is obvious.
Accompanying drawing is a circuit diagram of the present utility model.
