Abstract
The utility model relates to a stepless light-adjusting electronic ballasting device of an energy-saving lamp, which belongs to the field of electronic ballasting of the energy-saving lamp. Compared with the traditional daylight lamp ballasting, energy-saving lamp ballasting has the advantages of energy saving, glow starting, etc., but the existing energy-saving lamp can not adjust light and even can not continuously adjust the light. The utility model utilizes the characteristic that a high-frequency current is sensitive to the change of the inductance quantity of an inductance coil, the output end is connected in series with a magnetic core coil to change the inductance quantity of the coil so as to achieve the purpose of light adjustment; besides, the inductance quantity of a feedback coil of the base of a triode can be changed so as to achieve the purpose of light adjustment.
Description
Technical field the utility model belongs to energy-saving lamp electronic ballast field.
The more traditional fluorescent lamp ballast of background technology electricity-saving lamp ballast has many advantages at aspects such as economize on electricity build-ups of luminance, but electricity-saving lamp still can not light modulation at present, more can not continuous light tuning.The utility model utilizes high-frequency current that the inductance coil inductance value is changed responsive this characteristic, seals in a magnetic core coil at output, changes winding inductance quantity, reaches the light modulation purpose; Also can reach the light modulation purpose by changing transistor base feedback coil inductance value.
The summary of the invention the purpose of this utility model just provides a kind of electricity-saving lamp stepless dimming electronic ballast device.The signal of the utility model circuit theory as shown in Figure 1.T1a T1b T1c is that pulse transformer is the base stage feedback coil, and L2 is a choking-winding, and L3 is a dimmer, and LT is a dc coil.Behind output L2, be connected in series the adjustable coil L3 of a magnetic core again, regulate magnetic core and coil relative position, change its inductance value, thereby change the output current size, reach the light modulation purpose.
Among description of drawings Fig. 1, the transistor base feedback coil also is the magnetic core adjustable coil, changes magnetic core and coil relative position, changes its inductance value, thereby has changed the size of base stage feedback current, reaches the light modulation purpose.When the L3 coil design was fixed coil, the externally-applied magnetic field of available permanent magnet changed the inductance value of L3, reaches the light modulation purpose.
Embodiment base stage feedback coil also can be designed to fixed coil, close with permanent magnet equally or leave mode, thereby change base stage feedback current size and reach the light modulation purpose, in base stage feedback fixed coil, add around one-level dc coil LT and regulate the variable resistor resistance, change size of current among the dc coil LT, thereby change base stage feedback coil inductance value, reach the light modulation purpose.
The utility model compared with prior art has following advantage:
1, can realize stepless dimming, and the dimming scope broad, adjustable range can reach 3-35 watt.
2, dimming mode is various and convenient.With the 35W electricity-saving lamp is example, and among Fig. 1, L3 coil or base stage feedback coil can the medium wave bar magnet be magnetic core, and it is comparatively convenient to regulate inductance.Among Fig. 1, the power supply of the added dc coil LT of base stage feedback line, available electric capacity are supplied with after with civil power step-down and bridge rectifier; Dc coil is many around several circles, can correspondingly reduce the capacitance of decompression capacitor, minimal power consumption.
Claims (3)
1, the utility model is that a kind of higher-order of oscillation principle of using produces high-frequency and high-voltage to start the luminous electricity-saving lamp stepless dimming electronic ballast device of electricity-saving lamp, it is characterized in that: it can be that inductance value can be made continually varying coil, i.e. dimmer do relative displacement with coil that this ballast higher-order of oscillation output choke place is connected in series a magnetic core again.
2, electricity-saving lamp stepless dimming electronic ballast device according to claim 1, it is characterized in that: this dimmer can be designed to the fixed coil that magnetic core and coil are not done relative displacement, and with a permanent magnet gradually near or leave this coil so that winding inductance quantity is done to change continuously.
3, electricity-saving lamp stepless dimming electronic ballast device according to claim 1 is characterized in that: can add on the base stage feedback coil around one-level direct current coil again, regulate the size of current of this direct current coil and change this winding inductance quantity.
